Abstract
PURPOSE This study aimed to assess the efficacy of traditional Chinese medicine (TCM) in septic patients treated with ulinastatin. METHODS PubMed, EmBase, and the Cochrane library were searched up to January 2021 to identify randomized controlled trials. The weight mean difference (WMD) and relative risk (RR) with 95% confidence intervals were used with the random-effects model. RESULTS Twenty-three randomized controlled trials with 1903 septic patients were included. TCM significantly reduced the APACHE II score (WMD: -5.18; P < .001), interleukin-6 (WMD: -63.00; P < .001), tumor necrosis factor-α (WMD: -8.86; P < .001), c-reactive protein (WMD: -9.47; P < .001), mechanical ventilation duration (WMD: -3.98; P < .001), intensive care unit stay (WMD: -4.18; P < .001), procalcitonin (WMD: -0.53; P < .001), lipopolysaccharide (WMD: -9.69; P < .001), B-type natriuretic peptide (WMD: -159.87; P < .001), creatine kinase isoenzyme MB (WMD: -45.67; P < .001), cardiac troponin I (WMD: -0.66; P < .001), and all-cause mortality risk (RR: 0.55; P < .001). CONCLUSIONS TCM lowers inflammation levels and reduces the risk of all-cause mortality for septic patients.

Abstract
The aim of this research is to observe the effect of insulin pump combined with Ulinastatin on the levels of procalcitonin (PCT), triglycerides (TG), pentraxin-3(PTX-3), and C-X3-C motif chemokine ligand 1 (CX3CL1) in patients with diabetic ketoacidosis and pancreatitis.A total of 72 patients with diabetic ketoacidosis and pancreatitis who were admitted to our hospital from February 2016 to February 2020 were selected as the research subjects. They were divided into study groups (36 cases, given insulin pump combined Ulinastatin treatment) and control group (36 cases, given insulin pump treatment). Statistics of changes in blood amylase (AMS), blood glucose, blood ketones, glycosylated hemoglobin (HbA1c), PCT, TG, PTX-3, and chemokine CX3CL in pancreatic tissue before and after treatment.After treatment, the clinical efficacy of the study group was significantly higher than that of the control group (94.44% vs 75.00%), the difference was significant (P < .05). After treatment, the clinical symptoms (abdominal distension, abdominal pain, body temperature, blood sugar, HbA1c and blood amylase) in the study group were significantly less time-to-normal than in the control group, and the difference was significant (P < .05). After treatment, the AMS, blood sugar, HbA1c, and blood ketones of the 2 groups were all lower than before treatment, and the study group's AMS, blood sugar, HbA1c, and blood ketones were all lower In the control group, the difference was significant (P < .05). After treatment, the 2 groups of PCT, TG, PTX-3, and CX3CL were all lower than before treatment, among which the study group PCT, TG, PTX-3, and CX3CL1 were lower than the control group, the difference was significant (P < .05). After treatment, the total adverse reaction rate of the 2 groups was not significantly different (P > .05), but the total adverse reaction rate of the study group was lower than that of the control group.The combination of insulin pump and ulinastatin in the treatment of patients with diabetic ketoacidosis complicated with acute pancreatitis has a effect, which can shorten the recovery time of clinical symptoms, reduce the levels of PCT, TG, PTX-3, and CX3CL1, and has fewer adverse reactions. It is worthy of clinical application.

Abstract
This retrospective study aimed to investigate the efficacy and safety of existing approach of ulinastatin for the treatment of severe sepsis (SS).A total of 130 eligible patients with SS were included in this study. We divided them into an intervention group (n = 65) and a control group (n = 65). Patients in both groups received conventional therapy. In addition, patients in the intervention group received ulinastatin for 7 days. Outcomes were measured by Acute Physiology and Chronic Health Evaluation II (APACHE II), Multiple Organ Failure (MOF), Glasgow Coma Scale (GCS), CD3, CD4, CD8, CD4/CD8, and adverse events. We assessed all outcomes before and after treatment.After treatment, patients in the intervention group showed better improvement in APACHE II (P < .01), MOF (P < .01), GCS (P < .01), CD3 (P = .03), CD4 (P = .03), and CD4/CD8 (P < .01), than those of patients in the control group. There are similar safety profiles between both groups.This study suggests that ulinastatin may be beneficial for SS. Future studies are still needed to warrant the results of this study.

Abstract
Hepatic encephalopathy (HE) is a devastating neuropsychiatric presentation of the advanced hepatic insufficiency. It is associated with high morbidity and mortality. Aquaporin-4 (AQP4), the principal astrocyte water channel, is primarily involved in brain edema development. Ulinastatin (ULI) is a potent protease inhibitor, extracted from fresh human urine. We hypothesized that ULI could be neuroprotective in acute HE through molecular targeting of brain AQP4, which is known to be upregulated in HE. To induce acute liver failure (ALF), the rats were acutely intoxicated with thioacetamide (TAA). Animals were randomized into HE- and ULI-treated HE groups, with control normal group. Total bilirubin, albumin, serum aminotransferases, and serum/brain ammonia/proinflammatory cytokines, blood-brain barrier (BBB) integrity/tight junction proteins, brain water content, and neurological scores were assessed. Additionally, brain AQP4 and α-Syntrophin mRNA expression and protein levels were evaluated by quantitative real-time PCR and enzyme-linked immunosorbent assay, respectively. Brain and liver tissues were stripped and processed for further microscopic and histological analyses. ULI exerted potent dual neuro/hepato protective potential, improved neurological score, animals' survival, ameliorated brain edema, probably via anti-inflammatory activity, preserved BBB integrity, down-regulated AQP4 expression, and membrane polarization by decreased α-syntrophin level, with rescued brain bioenergetics. ULI could be tooled as a possible therapeutic option in HE in ALF.Graphical abstract The possible ULI mediated protection in TAA-induced HE rat model.

Abstract
BACKGROUND Sepsis is the leading cause of death in critically ill patients. Ulinastatin (UTI), a protease inhibitor, and rhubarb, used as a traditional Chinese medication, are proved to be effective in treating sepsis, but the effect of the combination therapy of these two drugs on sepsis remains unclear. This study aimed to investigate the effect of the combination treatment of UTI and rhubarb on sepsis patients. METHODS A total of 75 septic patients were randomly divided into control group, UTI group, Rhubarb group, and UTI plus Rhubarb group. Clinical data and score of Acute Physiology and Chronic Health Evaluation II (APACHE II) were collected; lymphocyte subtypes in the peripheral blood were analyzed before and after the 5-day treatment in the Intensive Care Unit. RESULTS All the therapeutic interventions (UTI alone, rhubarb alone, or UTI plus rhubarb) significantly reduced the levels of C-Reactive protein, white blood cell density, lactic acid, and APACH II scores, and elevated the levels of CD4/CD8, but only UTI plus rhubarb treatment obviously decreased the level of procalcitonin. CONCLUSION This study suggested that the combination of UTI and rhubarb may be a promising therapeutic scheme to ameliorate sepsis.

Abstract
In vivo studies show the benefits of the trypsin inhibitor isolated from tamarind (Tamarindusindica L.) (TTI) seeds in satiety and obesity. In the present study, TTI nanoencapsulation (ECW) was performed to potentialize the effect of TTI and allow a controlled release in the stomach. The impact on glycemia, insulin, and lipid profile was evaluated in Wistar rats overfed with a high glycemic index diet (HGLI). Characterization of the nanoparticles and in vitro stability in simulated gastrointestinal conditions, monitored by antitrypsin activity and HPLC, was performed. ECW and empty nanoparticles (CW) were administered by gavage, using 12.5 and 10.0 mg/kg, respectively. Both nanoformulations presented a spherical shape and smooth surface, with an average diameter of 117.4 nm (24.1) for ECW and 123.9 nm (11.3) for CW. ECW maintained the antitrypsin activity (95.5%) in the gastric phase, while TTI was completely hydrolyzed. In Wistar rats, the nanoformulations significantly reduced glycemia and HOMA IR, and ECW increased HDL-c compared to CW (p < 0.05).Pancreas histopathology of animals treated with ECW suggested an onset of tissue repair. Thenanoencapsulation provided TTI protection, gradual release in the desired condition, and improvement of biochemical parameters related to carbohydrate metabolism disorders,without compromising insulinemia.

Abstract
BACKGROUND Severe acute pancreatitis (SAP) is a severe form of inflammatory disease with a high mortality rate. Ulinastatin, as a urinary trypsin inhibitor (UTI), is a glycoprotein playing a critical role in SAP. Consequently, we identified the hypothesis that both matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) gene polymorphisms might promote the efficacy of ulinastatin in SAP. METHODS A total of 235 patients with SAP were treated by intravenous drip of ulinastatin for the duration of 10 days. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was performed for testing the distribution of genotypes and alleles frequency of MMP-2 and MMP-9 gene polymorphisms, and analyzing association of MMP-2 rs243865, MMP-2 rs2285053, MMP-9 rs3918242, or MMP-9 rs17576 with efficacy of ulinastatin in patients with SAP. Shesis software was adopted for analyzing single genotypes of MMP-2 and MMP-9 gene polymorphisms site A Generalized Multifactor Dimensionality Reduction (GMDR) model and a logistic regression analysis were used for analyzing effect of MMP-2 and MMP-9 gene polymorphisms on the efficacy of ulinastatin in treating patients with SAP. RESULTS CC genotype of MMP-2 gene rs243865 C>T was observed to have a better positive effect in promoting the efficacy of ulinastatin in comparison with CT and TT genotypes. Haplotype CCTG, CCTA, CTTG, and CTTA were combined by MMP-2 and MMP-9 gene polymorphisms which have the ability to increase the efficacy of ulinastatin in treating patients with SAP. MMP-2 gene rs243865 C>T site polymorphism was served as a favorable factor while the MMP-9 gene rs3918242 C>T site polymorphism was noticed as an unfavorable factor for the efficacy of ulinastatin in treating patients with SAP. CONCLUSION The key findings clearly demonstrated that both the MMP-2 rs243865 and MMP-9 rs3918242 gene polymorphisms served as biological indicators for the efficacy of ulinastatin in treating patients with SAP.

Abstract
INTRODUCTION Acute respiratory distress syndrome (ARDS) is challenging in the intensive care unit (ICU). Although pharmacotherapy for ARDS has gained increasing attention, most trials have yielded negative results. Patients with ARDS have usually been recruited as subjects; the inflammatory reaction has already expanded into a cascade at this point, and its severity is sufficient to damage the lung parenchyma. This raises the question of whether early treatment can prevent ARDS and the associated lung injury. We hypothesise that ARDS is preventable in high-risk patients by administration of ulinastatin as an anti-inflammatory drug before ARDS onset, and we are performing a study to test ulinastatin, a protease inhibitor, versus treatment-as-usual in a group of patients at increased risk for ARDS. METHODS AND ANALYSIS This report presents the protocol for a multicentre, randomised, conventional treatment-controlled, parallel group study to prevent the development of ARDS using ulinastatin in high-risk patients. The study population will comprise patients at risk of ARDS in the ICU (≥18 years of age and Lung Injury Prediction Score of >4); patients with confirmed ARDS and some other conditions (immunodeficiency, use of some drugs, etc.) will be excluded. The enrolled patients will be randomly allocated to an ulinastatin group (ulinastatin will be intravenously administered every 8 hours for a total of 600 000 U/day for five consecutive days) or control group. The efficacy of ulinastatin in preventing ARDS development will be evaluated by the incidence rate of ARDS as the primary outcome; the secondary outcomes include the severity of ARDS, clinical outcome, extrapulmonary organ function and adverse events incurred by ulinastatin. Based on the results of preliminary studies and presuming the incidence of ARDS will decrease by 9% in high-risk patients, 880 patients are needed to obtain statistical power of 80%. ETHICS AND DISSEMINATION This study has been approved by the Peking University Third Hospital Medical Science Research Ethics Committee. The findings will be published in peer-reviewed journals and presented at national and international conferences. TRIAL REGISTRATION NUMBER NCT03089957; Pre-results.

Abstract
BACKGROUND Sepsis is a clinically critical disease. However, it is still controversial whether the combined use of traditional Chinese medicine Xuebijing injections (XBJI) and western medicine can enhance curative efficacy and ensure safety compared with western medicine alone. Thus, this research consisted of a systematic review of the curative efficacy and safety of traditional Chinese medicine XBJI combined with ulinastatin for treating sepsis in the Chinese population. METHODS A total of 8 databases were retrieved: 4 foreign databases, namely, PubMed, The Cochrane Library, Embase, and Web of Science; and 4 Chinese databases, namely, Sino Med, China National Knowledge Infrastructure (CNKI), VIP, and Wangfang Data. The time span of retrieval began from the establishment of each database and ended on August 1, 2017. Published randomized controlled trials about the combined use of traditional Chinese medicine XBJI and western medicine were included, regardless of language. Stata12.0 software was used for statistical analysis. RESULTS Finally, 16 papers involving 1335 cases were included. The result of meta-analysis showed that compared with the single use of ulinastatin, traditional Chinese medicine XBJI combined with ulinastatin could reduce the time of mechanical ventilation, shorten the length of intensive care unit (ICU) stay, improve the 28-day survival rate, and decrease the occurrence rate of multiple organ dysfunction syndrome, case fatality rate, procalcitonin (PCT) content, APACKEII score, tumor necrosis factor (TNF)-α level, and interleukin (IL)-6 level. CONCLUSION On the basis of the common basic therapeutic regimen, the combined use of traditional Chinese medicine XBJI and ulinastatin was compared with the use of ulinastatin alone for treating sepsis in the Chinese population. It was found that the number of adverse events of combination therapy is not significantly increased, and its clinical safety is well within the permitted range. However, considering the limitations of this conclusion due to the low-quality articles included in the present research, it is necessary to conduct high-quality randomized controlled trials.

Abstract
BACKGROUND The potential benefits and possible risks associated with Xuebijing when combined with ulinastatin for sepsis treatment are not fully understood. METHODS Databases, such as PubMed, Web of Science, CNKI, WanFang and VIP, were searched to collect randomized, controlled trials. Studies were screened, data were extracted, and the methodological quality was assessed by two reviewers independently. A meta-analysis was carried out with Stata 11.0 software. RESULTS A total of 16 studies involving 1192 participants were enrolled for meta-analysis based on the inclusion and exclusion criteria. The results showed that compared with the group using routine therapies and the group using a single administration of either ulinastatin or Xuebijing, the trial group using Xuebijing combined with ulinastatin was significantly superior in the following aspects: mortality (RR = 0. 54,95% CI (0. 41, 0. 70, P = .000), 7 d APACHE II (SMD = -1.21, 95%CI (-1.62, -0.80), P = .000), duration of mechanical ventilation (SMD = -1.21, 95%CI (-1.62, -0.80), P = .000), average length of time in the intensive care unit (SMD = -1.21, 95%CI (-1.62, -0.80), P = .000), incidence of multiple organ dysfunction syndromes (RR = 0. 54, 95% CI (0.41, 0. 70, P = .000), interleukin-6 (SMD = -1.36,95%CI (-2.46, -0.27), P = .000), lipopolysaccharide (SMD = -9.92, 95%CI (-11.7, -7.90), P = .006), and procalcitonin (SMD = -0.30, 95%CI (-0.34, -0.26), P = .012). CONCLUSIONS Our results found that Xuebijing when combined with ulinastatin was superior to both routine therapies and the single administration of either ulinastatin or Xuebijing. This finding provides a new therapeutic option for the treatment of sepsis.

Abstract
Postoperative pancreatic fistula (POPF) is one of the most common major complications after pancreaticoduodenectomy (PD). Ulinastatin is an intrinsic trypsin inhibitor and mainly used to treat acute pancreatitis, chronic recurrent pancreatitis, and acute circulatory failure. The study aims to investigate the efficacy of ulinastatin on pancreatic fistula and other complications after PD. This prospective, randomized, double-blind, placebo-controlled trial was conducted in West China Hospital of Sichuan University from December 2012 to December 2014. A total of 106 consecutive patients undergoing PD were randomly assigned to receive ulinastatin or placebo during and after the surgery for 5 days. Baseline clinical characteristics and outcomes of patients were recorded and analyzed. Ninety-two patients including 42 in the ulinastatin group and 50 in the placebo group were available for outcome assessment. The POPF rates were comparable between ulinastatin group (43%) and placebo group (26%), whereas the severe pancreatic fistula rate (grade B + C) was significantly less in ulinastatin group than that in placebo group (7% vs 24%, P = 0.045). For patients with small pancreatic duct diameter (≤3 mm), ulinastatin could significantly reduce the risk of POPF (P = 0.022). Ulinastatin had protective effects for patients undergoing PD on the prevention of severe postoperative pancreatic fistula.

Abstract
Total ginsenosides synergize with ulinastatin (UTI) against septic acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). We randomly divided 80 cases of severe sepsis-induced ALI and ARDS into a UTI group and a ginsenosides (GS)+UTI group. Continuous electrocardiac monitoring of pulse, respiratory rate, blood pressure, and heart rate; invasive hemodynamic monitoring; ventilator-assisted breathing and circulation support; and anti-infection as well as UTI treatment were given in the UTI group with GS treatment added for 7 consecutive days in the GS+UTI group. The indicators of pulmonary vascular permeability, pulmonary circulation, blood gases, and hemodynamics as well as APACHE II and ALI scores were detected on days 1, 3, and 7. The ALI score in the GS+UTI group was significantly decreased (P < 0.05) compared with that of the UTI group, and the indicators of pulmonary capillary permeability such as pulmonary vascular permeability index, extravascular lung water index, and oxygenation index, in the GS+UTI group improved significantly more than that of the UTI group. The indicators of hemodynamics and pulmonary circulation such as cardiac index, intrathoracic blood volume index, and central venous pressure improved significantly (P < 0.05), and the APACHE II score in the GS+UTI group was lower than that of the UTI group. GS can effectively collaborate with UTI against ALI and/or ARDS.

Abstract
Purpose Ulinastatin, a serine protease inhibitor, inhibits several pro-inflammatory proteases and decreases inflammatory cytokine levels and mortality in experimental sepsis. We studied the effect of ulinastatin on 28-day all-cause mortality in a double-blind trial in patients with severe sepsis in seven Indian hospitals. Methods Patients with sepsis were randomized within 48 h of onset of one or more organ failures to receive intravenous administration of ulinastatin (200,000 IU) or placebo 12 hourly for 5 days. Results Of 122 randomized subjects, 114 completed the study (55 receiving ulinastatin, 59 receiving placebo). At baseline, the mean APACHE II score was 13.4 (SD = 4.4), 48 (42 %) patients were receiving mechanical ventilation, 58 (51 %) were on vasopressors, and 35 % had multiple organ failure. In the modified intention-to-treat analysis (patients receiving six or more doses of study drugs), 28-day all-cause mortality was 7.3 % with ulinastatin (4 deaths) versus 20.3 % (12 deaths) with placebo (p = 0.045). On multivariate analysis too, treatment with ulinastatin (odds ratio 0.26, 95 % CI 0.07–0.95; p = 0.042) independently decreased 28-day all-cause mortality. However, the mortality difference did not reach statistical significance in the intention-to-treat analysis [10.2 % (6/59 deaths) with ulinastatin versus 20.6 % (13/63 deaths) in the placebo group; p = 0.11]. The ulinastatin group had lower incidence of new-onset organ failure (10 vs. 26 patients, p = 0.003), more ventilator-free days (mean ± SD 19.4 ± 10.6 days vs. 10.2 ± 12.5 days, p = 0.019), and shorter hospital stay (11.8 ± 7.1 days vs. 24.2 ± 7.2 days, p < 0.001). Conclusions In this pilot study, intravenous administration of ulinastatin reduced mortality in patients with severe sepsis in the modified intention-to-treat analysis, but not in the intention-to-treat analysis.

Abstract
OBJECTIVE To investigate the effects of Ulinastatin with different doses on pulmonary protection after cardiopulmonary bypass (CPB). METHODS Ninety patients after CPB were brought into this study and divided into low doses Ulinastatin group (L group, n=30, 5 000 U/kg), high doses Ulinastatin group (H group, n=30, 20 000 U/kg) and control group (C group, n= 30), respectively. When the patients were transferred into ICU after CPB, Ulinastatin was given intravenously to those in L and H group, while saline was given in C group. Blood samples were harvested at the time before the treatments (T0) and 12 hours (T1), 24 hours (T2) after the treatments, for the measurements of arterial pressure of oxygen (PaO2), arterial pressure of carbon monoxide (PaCO2),difference of alveoli-arterial oxygen pressure (PO(2A), oxygenation index (Ol),and tumor necrosis factor-alpha (TNF-alpha) level. Pulmonary dynamic compliance (Cd), plat pressure (Pplat) and peak pressure (Ppeak) were determined at the time of To and wean (Tw). The durations of ventilation and intubation were recorded. RESULTS At T0, the levels of PaO2, PaCO2, PO2A-a, OI and TNF-alpha in each group showed no significantly difference (P> 0. 05). At T1 and T2, the patients in H group had higher levels of PO2, PO2A-a. and OI, lower level of TNF-alpha, shorter duration of ventilation and intubation than the patients in other two groups(P<0. 05). The parameters in L group were better than those in C group, but the differences were not stastically significant (P>0. 05). There was no significantly difference in the levels of Cd, Pplat, and Ppeak at T0 and Tw between any two groups (P>0. 05). The intubation and ventilation time in H group were shorter than that in L and C group (P<0. 05). CONCLUSION The application of Ulinastatin could achieve pulmonary protective effect after CPB, and it seems the effect could be better with high dose (20 000 U/kg) of Ulinastatin.

Abstract
BACKGROUND AND AIMS Endoprotease activation is a key step in acute pancreatitis and early inhibition of these enzymes may protect from organ damage. In vivo models commonly used to evaluate protease inhibitors require animal sacrifice and therefore limit the assessment of dynamic processes. Here, we established a non-invasive fluorescence imaging-based biomarker assay to assess real-time protease inhibition and disease progression in a preclinical model of experimental pancreatitis. METHODS Edema development and trypsin activation were imaged in a rat caerulein-injection pancreatitis model. A fluorescent "smart" probe, selectively activated by trypsin, was synthesized by labeling with Cy5.5 of a pegylated poly-L-lysine copolymer. Following injection of the probe, trypsin activation was monitored in the presence or absence of inhibitors by in vivo and ex vivo imaging. RESULTS We established the trypsin-selectivity of the fluorescent probe in vitro using a panel of endopeptidases and specific inhibitor. In vivo, the probe accumulated in the liver and a region attributed to the pancreas by necropsy. A dose dependent decrease of total pancreatic fluorescence signal occurred upon administration of known trypsin inhibitors. The fluorescence-based method was a better predictor of trypsin inhibition than pancreatic to body weight ratio. CONCLUSIONS We established a fluorescence imaging assay to access trypsin inhibition in real-time in vivo. This method is more sensitive and dynamic than classic tissue sample readouts and could be applied to preclinically optimize trypsin inhibitors towards intrapancreatic target inhibition.

Abstract
Trypsin inhibitors (TIs) have various nutritional effects. However, a detailed mechanism for their effects, especially on the gene expression patterns in various tissues, remains unknown. Here, we used transcriptome techniques and gene ontology (GO) analysis to examine the effects of squid TI (sqTI), a biochemically stable peptide, on diabetic Goto-Kakizaki rats after feeding for 10 weeks. We demonstrated that downregulation of SREBP1c in the liver via duodenal/pancreatic hormones suppresses the blood cholesterol level. Consistently, in GO analysis, the term "cholesterol biosynthetic process" was enriched among downregulated genes. No hypoglycemic or insulinotropic effects were observed, in contrast to the results from our previous studies (single stimulation with the same dose of TI), which can be partly ascribed to the inactive responses of the duodenum and pancreas in this condition.

Abstract
To investigate the effects of oral administration of a trypsin inhibitor (TI), normal Wistar rats were fed a TI derived from squid (Todarodes pacificus) for 10 weeks and gene expression profiles in the duodenum, pancreas, liver, and muscle were then analyzed using DNA microarrays. Although no significant changes could be observed in growth, food intake, tissue weight, or blood tests among the tissues tested, the duodenum showed the most remarkable changes in the global gene expression profile. Significant up-regulation of mRNAs encoding gastrin, gastrokine, cholecystokinin and somatostatin in the duodenum was validated by qPCR analysis. In gene ontology (GO) analysis of the up-regulated differentially expressed genes (DEGs), GO terms related to keratinization and innate mucosal defense were enriched (p < 0.001) in the category of biological processes in addition to assumable terms such as regulation of secretion and response to nutrients, vesicle-mediated transport, and so forth. In the same analysis, calcium ion binding was listed at the deepest hierarchy in the category of molecular function. These results indicate that the duodenum responds to TI treatment by a wider range of physiological processes than previously assumed such as keratinocyte differentiation and innate mucosal defense, in which calcium plays a crucial role.

Abstract
OBJECTIVE To investigate the effect of intraluminal administration of ulinastatin (a protease inhibitor) in the intestine on intestinal inflammation in rats with hemorrhagic shock. METHODS Twenty-eight Wistar rats were randomized into control group (A), intestinal saline perfusion group (B), ulinastatin intestinal perfusion group (C), and intravenous ulinastatin injection group (D) (n=7). The mean arterial blood pressure (MAP) and survival time of the rats were recorded. The changes in human polymorphonuclear cell (PMN) CD11b expression were detected by flow cytometry. The leukocyte count was recorded at different time points after the treatment, and the pathology of the intestinal mucosa was observed comparatively. RESULTS Groups C and D showed significantly slower reduction of the MAP than groups A and B after hemorrhagic shock (P<0.05). The survival time of the rats was the longest in group C (P<0.05). CD11b expression increased gradually during hemorrhagic shock in all the groups, but the expression level was the lowest in group C (P<0.05). Hemorrhagic shock caused a reduction in leukocyte counts, which remained the highest in group C (P<0.05). Group C also showed the least intestinal pathology among the 4 groups. CONCLUSION Intestinal perfusion of ulinastatin can lower the reduction rate of MAP, attenuate plasma activation and intestinal inflammation, and prolong the survival of rats with hemorrhagic shock. These results indicate an important role of protease in intestinal inflammation during hemorrhagic shock.

Abstract
We describe a case of congenital meconium peritonitis with progressive fetal ascites and polyhydramnios. Fetal ascites could be only partially reduced on paracentesis at 29 weeks' gestation, and it subsequently increased. Urinary trypsin inhibitor (UTI), a physiological anti-inflammatory substance, was administered into the fetal abdominal cavity at a second paracentesis performed at 35 weeks' gestation. There was a significant amount of fetal ascites remaining 1 day after the second paracentesis, but this completely resolved within 5 days. A healthy infant was delivered vaginally and no surgical intervention was required. The case suggests that UTI can reduce meconium-induced chemical peritonitis and thereby facilitate intrauterine remission of fetal ascites.

Abstract
We reviewed the benefits and harms of augmentation therapy with alpha-1 antitrypsin in patients with alpha-1 antitrypsin deficiency and lung disease. We searched for randomised trials comparing augmentation therapy with placebo or no treatment in PubMed and ClinicalTrials (7 January 2010). Two trials were included with a total of 140 patients. The trials ran for two to three years. Mortality data were not reported. There was no information on harms in the first trial; in the second trial, serious adverse events were reported in ten of 38 patients in the drug group and in 18 of 39 patients in the placebo group. Annual number of exacerbations and quality of life were reported in the second trial and were similar in the two groups. The meta-analyses showed that forced expiratory volume in one second deteriorated a little more in the drug group than in the placebo group (difference -20 ml per year; 95% confidence interval -41 to 1; p = 0.06). For carbon monoxide diffusion, the difference was -0.06 mmol/min./kPa per year (95% confidence interval -0.17 to 0.05; p = 0.31). Lung density measured by computed tomography deteriorated a little less in the drug group than in the placebo group (difference 1.14 g/l; 95% confidence interval 0.14 to 2.14; p = 0.03) over the total course of the trials. Augmentation therapy with alpha-1 antitrypsin cannot be recommended in view of the lack of evidence of clinical benefit and the cost of treatment.

Abstract
BACKGROUND We sought to study the effect of a combination therapy comprised of hyperbaric oxygen (HBO) and ulinastatin on the plasma levels of endotoxin, soluble CD14 (sCD14), endotoxin neutralizing capacity (ENC) and cytokines in acute necrotizing pancreatitis (ANP) in rats. METHODS We randomly allocated 90 Sprague-Dawley rats into 6 groups: group 1 (ordinary control), group 2 (sham operation), group 3 (ANP), group 4 (ANP with HBO), group 5 (ANP with ulinastatin) and group 6 (ANP with HBO and ulinastatin). We induced ANP by retrograde injection of 3.5% sodium taurocholate (2.5 mL/kg) via the pancreatic duct. Five minutes after induction, animals in groups 5 and 6 were infused with ulinastatin (20 000 U/kg) via the portal vein. Thirty minutes after induction, animals in groups 4 and 6 received HBO therapy. We collected samples 3, 6 and 10 hours after induction of ANP. RESULTS We found that the plasma level of endotoxin in group 3 was significantly higher than in group 4 (3, 6 h, both p < 0.001), group 5 (3 h, p < 0.001; 6 h, p = 0.014) and group 6 (both p < 0.001). The level of plasma sCD14 in group 3 was significantly higher than in group 4 (3, 6 h, both p < 0.001), group 5 (3, 6 h, both p = 0.001) and group 6 (3 h, p < 0.001; 6 h, p = 0.001). The plasma endotoxin and sCD14 levels in group 6 were significantly lower than in groups 4 and 5. The plasma ENC level in group 6 was significantly higher than in groups 3, 4 and 5 (p < 0.001). The ENC level in groups 4 and 5 were higher than in group 3, but there was no significant difference. The plasma level of tumour necrosis factor-alpha (TNF-alpha) and IL-6 in group 6 were significantly lower than in groups 3, 4 and 5 (p < 0.001). The TNF-alpha and IL-6 levels in groups 4 and 5 were lower than in group 3, but there was no significant difference. CONCLUSION The use of an early combination therapy of HBO and ulinastatin was more effective than either therapy alone in the treatment of ANP.

Abstract
Ulinastatin, a trypsin inhibitor, is useful as a first-line or a second-line treatment regimen including alternative therapy for IVIG-resistant or IVIG nonresponder Kawasaki disease (KD) patients. Mechanisms involving protections against tissue organs and endthelial cell and anti-inflammatory effects by ulinastatin, are dependent on the inhibition of PMN-derived elastase, tumor necrosis factor alpha (TNFalpha), and other proinflammatory cytokines/interleukins(IL-1, IL-6, IL-8). Ulinastatin also suppresses the activation of PMN cells, macrophages, and platelets. Although almost no statistical data related to the definitive effect in acute stage of KD, ulinastatin have shown possible effects, but not always, in a part of KD patients. The indications of clinical use include shock and pancreatitis. Off-label uses of ulinastatin have been reported in hematological, hepatic, renal, OB/Gy diseases and cardiovascular diseases including vasculitis syndromes. The efficacy of ulinastatin in aKD remained to be investigated.

Abstract
A trypsin inhibitor was isolated from Cassia obtusifolia by ammonium sulfate precipitation, Sepharose 4B-trypsin affinity and Sephadex G-75 chromatography. The inhibitor consisted of a single polypeptide chain with a molecular mass of 19, 812.55 Da. It was stable from pH 2 to 12 for 24 h, whereas it was unstable either above 70 degrees C for 10 min or under reduced conditions. The inhibitor, which inhibited trypsin activity with an apparent Ki of 0.3 microM, had one reactive site involving a lysine residue. The native inhibitor was resistant to pepsin digestion, whereas the heated inhibitor produced 40% degree of susceptibility. The disulfide linkage and lysine residue were important in maintaining its conformation. Partial amino acid sequence of the purified protein showed a high degree of homology with various members of the Kunitz inhibitor family. Moreover, the inhibitor showed significant inhibitory activity against trypsin-like proteases present in the larval midgut on Pieris rapae and could suppress the growth of larvae.

Abstract
OBJECTIVES Proteases have been shown to play a role in the pathogenesis of otitis media. Inhibition of these proteases can improve treatment outcomes in certain conditions. The goal of this study was to determine if intratympanic administration of a single dose of the protease inhibitor, recombinant alpha 1-antitrypsin (rAAT), can facilitate resolution of acute otitis media (AOM) in the chinchilla. METHODS AND MEASURES Pneumococcus was injected into both middle ears of 12 chinchillas. After 3 to 4 days, middle ears were cultured, systemic antibiotics were initiated, and rAAT or its vehicle was administered into the middle ears of all animals. Serial tympanic membrane (TM) scoring, tympanometry, and auditory-evoked brain stem response testing were performed. Animals were sacrificed at varying timepoints and temporal bones studied for objective measures of OM. RESULTS Although not reaching statistical significance, there was a trend to more rapid resolution of AOM in rAAT-treated ears. Tympanometry, auditory thresholds, and quantitative histologic parameters did not differ between rAAT and vehicle treated ears. CONCLUSIONS A single dose of intratympanic rAAT likely does not facilitate the resolution of antibiotic-treated pneumococcal AOM in the chinchilla model. Serial administration of this protease inhibitor may be necessary to see a significant treatment effect.

Abstract
Present investigation was aimed at developing an oral insulin delivery system based on hydroxypropyl beta cyclodextrin-insulin (HPbetaCD-I) complex encapsulated polymethacrylic acid-chitosan-polyether (polyethylene glycol-polypropylene glycol copolymer) (PMCP) nanoparticles. Nanoparticles were prepared by the free radical polymerization of methacrylic acid in presence of chitosan and polyether in a solvent/surfactant free medium. Dynamic light scattering (DLS) experiment was conducted with particles dispersed in phosphate buffer (pH 7.4) and size distribution curve was observed in the range of 500-800 nm. HPbetaCD was used to prepare non-covalent inclusion complex with insulin and complex was analyzed by Fourier transform infrared (FTIR) and fluorescence spectroscopic studies. HPbetaCD complexed insulin was encapsulated into PMCP nanoparticles by diffusion filling method and their in vitro release profile was evaluated at acidic/alkaline pH. PMCP nanoparticles displayed good insulin encapsulation efficiency and release profile was largely dependent on the pH of the medium. Enzyme linked immunosorbent assay (ELISA) study demonstrated that insulin encapsulated inside the particles was biologically active. Trypsin inhibitory effect of PMCP nanoparticles was evaluated using N-alpha-benzoyl-L-arginine ethyl ester (BAEE) and casein as substrates. Mucoadhesive studies of PMCP nanoparticles were conducted using freshly excised rat intestinal mucosa and the particles were found fairly adhesive. From the preliminary studies, cyclodextrin complexed insulin encapsulated mucoadhesive nanoparticles appear to be a good candidate for oral insulin delivery.

Abstract
BACKGROUND beta-Tryptase is a multifunctional mast cell serine protease released during mast cell degranulation and tryptase/trypsin inhibitors are a novel potential therapeutic approach for allergic inflammatory diseases. OBJECTIVES This study was performed to assess the effects of RWJ-58643 on nasal symptoms, eosinophil influx, and cytokine and chemokine release following nasal allergen challenge (NAC). METHODS Male patients with grass pollen allergic rhinitis (n=16) out of season received single doses of RWJ-58643 (100, 300, 600 microg) or matched placebo given 30 min before NAC in a double-blind, randomized crossover design. A single dose of 200 microg budesonide was studied in an open-label extension phase. NAC was performed with Timothy grass pollen (ALK) via a nasal device, and nasal lavage was performed at times 0 (pre-drug, pre-allergen), 0.5 (30 min post-drug, pre-NAC) 1.5, 2.5, 4.5, 6.5, 8.5, and 24 h after drug administration. Nasal lavage mediators were analysed using a sensitive multiplexed bead immunoassay system. RESULTS Low-dose RWJ-58643 (100 microg) and budesonide (200 microg) significantly reduced symptoms, eosinophils and levels of IL-5 following NAC. However, higher doses of RWJ-58643 (300 and 600 microg) caused a late eosinophilia and preceding increases in IL-5 compared with placebo. CONCLUSIONS This study suggests that combined beta-tryptase and trypsin inhibition has therapeutic potential in allergic inflammation, however, this property is dose responsive and higher doses are ineffective and may cause eosinophilia.

Abstract
STUDY OBJECTIVE Abdominal aortic aneurysmectomy (AAAectomy) results in a general ischemia-reperfusion syndrome accompanied by an acute rise in pulmonary artery pressure (PAP). We examined whether ulinastatin, a urinary trypsin inhibitor, prevents ischemia-reperfusion injury and increase in PAP after aortic unclamping (XU) during AAAectomy. DESIGN Prospective study. SETTING Public, university-affiliated hospital. PATIENTS Sixteen patients (11 males and 5 females) scheduled for AAAectomy. INTERVENTIONS AND MEASUREMENTS The patients received 300000 IU of ulinastatin intravenously before XU (n = 8) or no additional treatment (n = 8) (control). Heart rate, central venous pressure, PAP, pulmonary arterial wedge pressure, arterial pressure, mixed venous oxygen saturation (Sv(O2)), and cardiac output were monitored. Arterial and mixed venous blood samples were analyzed for pH, Pa(CO2), Pa(O2), hemoglobin, and oxygen saturation, and the physiological shunt function (Qs/Qt) were calculated. Plasma concentrations of malondialdehyde, myeloperoxidase, granulocyte elastase, alpha1-antitrypsine, and thromboxane B2 and the stable hydrolysis products of thromboxane A2 were measured. Measurements were conducted before aortic crossclamping (XC) (baseline) and at 10, 30, and 60 minutes after XU. MAIN RESULTS A significant increase in PAP was observed 10 minutes after XU in the control group but not in the ulinastatin group. At 60 minutes after XU, Qs/Qt values had increased in the control group but had decreased in the ulinastatin group. There were no significant changes in malondialdehyde, thromboxane B2, granulocyte elastase, and alpha1-antitrypsine levels after XU in either group. A significant decrease in the plasma level of myeloperoxidase after XU was found in both groups. CONCLUSIONS The present study demonstrated that ulinastatin prevents increase in PAP and shunting after XU during AAAectomy.

Abstract
Alpha(1)-antitrypsin deficiency, a relatively frequent mutation in the population, is associated with the development of panlobular emphysema and liver cirrhosis. The deficiency is in rare cases associated with the development of panniculitis, and very differentiated clinical courses have been reported in the literature. We report a case of panniculitis in a patient with alpha(1)-antitrypsin deficiency and describe briefly the pathophysiology of the disease and current treatment possibilities.

Abstract
BACKGROUND AND AIM An oral trypsin inhibitor, camostat (CM), has a beneficial effect on chronic pancreatitis, but its mechanism is not yet fully understood. Recently, pancreatic stellate cells (PSC) have been reported to play an essential role in pancreatic fibrosis. An experimental model of pancreatic fibrosis induced by a superoxide dismutase (SOD) inhibitor (diethyldithiocarbamate [DDC]) was developed in rats. Thus, the effect of an oral trypsin inhibitor on pancreatic fibrosis and PSC was investigated. METHODS Pancreatic fibrosis was induced in rats using DDC (DDC rats). DDC + CM rats were administered DDC, and subsequently were fed a diet containing CM. Immunohistochemistry of the pancreas was performed with monoclonal anti-alpha-smooth muscle actin (alpha-SMA) antibody and anti-desmin antibody. RESULTS The DDC rats showed a significant increase in alpha-SMA-positive cells or desmin-positive cells compared with control rats. These significant increases in the fibrotic area improved after treatment with CM. The level of prolyl hydroxylase in the pancreas, which significantly increased as a result of DDC, decreased after treatment with CM. CONCLUSION Camostat has a beneficial effect on pancreatic fibrosis induced by the administration of a SOD inhibitor, which inhibits the proliferation and activation of PSC.

Abstract
BACKGROUND The acute respiratory distress syndrome (ARDS) is often caused by fat tissue embolism. One of the most common animal models of ARDS is produced by direct administration of oleic acid (OA). Activated leukocytes are critically involved in the pathological mechanism in this model. Human urinary trypsin inhibitor (UTI) is known to inhibit production of tumor necrosis factor (TNF)-alpha, which potently stimulates leukocyte activation. The purpose of this study was to clarify whether UTI improves OA-induced lung injury in rats by inhibiting activated leukocytes via TNF-alpha production. MATERIALS AND METHODS Rats were subjected to a single intravenous administration of OA into the pedicle vein. Acute lung injury was evaluated by arterial blood gases and histological changes in lungs. Pulmonary vascular permeability, accumulation of neutrophils, and the levels of TNF-alpha in lung tissues were also examined. Rats were divided into four experimental groups: a sham operated, OA, OA + UTI, and OA + nitrogen mustard (NM)-induced leukocytopenia group. UTI was intravenously administered 30 min before OA administration. Leukocytopenia was induced by the administration of NM. RESULTS UTI significantly improved the OA-induced histological changes for 4 h after OA administration. The OA-induced reduction of PaO2, the increase of pulmonary vascular permeability, and the levels of MPO activity and TNF-alpha in lung tissues were significantly improved in rats administrated UTI. The effects in the leukocytopenia group were similar to those in the UTI-administered group. CONCLUSION Leukocytes play a critical role in the development of OA-induced lung injury. It was suggested that UTI contributed to the reduction in the OA-induced lung injury by inhibiting TNF-alpha and thereby suppressing leukocyte.

Abstract
OBJECTIVE This study was to develop a suitable model for the investigation for food allergy. METHODS BALB/c mice were dosed by intraperitoneally with Ovalbumin, Beef serum albumin, Trypsin inhibitor and Potato acid phosphatase respectively (0.25ml 20mg/mnl) on day 0 and again on day 7. Control group was dosed with PBS. Sera form individual animals were analysed for specific IgE and Passive cutaneous anaphylaxis tests. Additionally, the level of histamine in plasma were detected. RESULTS The high titres of specific IgE (1: 32) could be provoked in test groups compared with control group. In addition, the level of histamine in plasma of test groups was higher than that in the control group. But there was no statistical significance between group food allergen and group Potato acid phosphatase. CONCLUSION Although allergic action of BALB/c mice could be provoked, the situation of the allergic action of BALB/c mice to the proteins was very different with the human being. The BALB/c mice could not be a suitable model for the investigation for food allergy.

Abstract
AIMS To assess the hypothesis that an additional intravenous gammaglobulin (IVGG) infusion, if administered early, may prevent coronary artery lesions (CAL) in patients with Kawasaki disease (KD) who do not respond to initial IVGG therapy. METHODS Forty four KD patients (17 with CAL and 27 without CAL), treated with additional IVGG because of persistent or recrudescent fever after initial IVGG therapy, were studied. Main outcome measures were the presence of CAL by echocardiography and the number of febrile days before and after start of additional IVGG infusion (pre- and post-additional IVGG). RESULTS In univariate analyses, risk factors for CAL were the number of febrile days pre-additional IVGG, the number of febrile days post-additional IVGG, the number of days that initial IVGG was divided over, the white blood cell count pre- and post-additional IVGG, and the C reactive protein concentration pre-additional IVGG. In a multivariate analysis, the only independent risk factor was the number of febrile days pre-additional IVGG (> or =10 days; odds ratio 7.86; 95% CI 1.44 to 42.8; p = 0.02). CONCLUSIONS Among KD patients with persistent or recrudescent fever after initial IVGG therapy, administration of additional IVGG before the first 10 febrile days was associated with a decreased prevalence of CAL, when compared with the prevalence in those who were retreated later. An additional IVGG infusion, if administered early, may prevent CAL in initial IVGG non-responders.

Abstract
Forty-eight Holstein bull calves were assigned to a 2 x 2 x 2 factorial arrangement in a completely randomized block design. Main effects were colostrum versus a serum-derived colostrum supplement, 0 versus 1 g of trypsin inhibitor added at the initial 2 feedings, and milk replacer containing 0 or 50% CP from whole egg. Calves were bled at 0, 6, 12, 18, and 24 h after birth for determination of serum immunoglobulin (Ig). G. Serum IgG concentrations were lower in calves consuming the colostrum supplement compared with calves consuming colostrum. Apparent efficiency of absorption of IgG was similar. Trypsin inhibitor did not affect IgG concentrations or absorption of IgG. Calves were fed either milk replacer for 28 to 35 d (preweaning phase) and weaned when they consumed 0.7 kg of starter grain for 2 consecutive days. The postweaning phase was from weaning to d 56. Feeding colostrum supplement resulted in higher fecal scores postweaning (1.90 vs. 1.58) and overall (1.85 vs. 1.65) and fewer days medicated preweaning (5.1 vs. 2.2 d) and postweaning (3.9 vs. 1.9 d) and overall (9.0 vs. 4.2 d). Calves were treated for upper respiratory tract infections and diarrhea. Dry matter intake and weaning age were not affected by treatment. Postweaning (1.69 vs. 1.2 kg) and overall (1.22 vs. 1.0 kg), calves that received colostrum and egg milk replacer consumed more dry matter and starter. Postweaning, calves fed colostrum and egg milk replacer had similar or greater body weight and gains compared with calves fed colostrum and milk protein milk replacer. Preweaning, feed efficiency was greater for calves fed colostrum (0.44 vs. 0.34), trypsin inhibitor (0.42 vs. 0.36), and milk protein milk replacer (0.48 vs. 0.30) compared with calves fed colostrum supplement, no trypsin inhibitor, and egg milk replacer, respectively. Trypsin inhibitor increased feed efficiency postweaning. Calves fed trypsin inhibitor and milk protein milk replacer were more efficient preweaning and overall than calves fed trypsin inhibitor and egg milk replacer. Results indicate that the blood derived colostrum supplement did not provide as much IgG as colostrum (4.55 g/L vs. 14.6 g/L, respectively), that feeding 1.0 g of trypsin inhibitor did not enhance serum IgG concentrations, and that the egg milk replacer-fed calves fed colostrum performed nearly as well as calves fed colostrum and the milk protein milk replacer.

Abstract
BACKGROUND Snail medic (Medicago scutellata L.) seeds exhibit a significantly higher content of a trypsin inhibitor than other Medicago species. This inhibitor belongs to the Bowman-Birk family of serine protease inhibitors (BBI) and exhibits a good sequence homology with the BBI from soybean, while presenting some differences. It has been suggested that BBIs have antitumoral and radio-protective activity. MATERIALS AND METHODS In order to assess whether the inhibitor from Medicago scutellata (MsTI) seeds show similar properties to those of BBI from soybean with respect to potentiation of cisplatin-induced cytotoxicity, we evaluated the effects of MsTI on cisplatin-induced cell killing in MCF7 human breast carcinoma cells and HeLa human cervical carcinoma cells. RESULTS The 24-hour treatment of MsTI in the cell culture medium decreased the clonogenic survival of MCF7 and HeLa cells in a dose-dependent manner and enhanced cisplatin-induced cytotoxicity. The presence of MsTI during the entire incubation period reduced the D37 of cisplatin by 40% in both the cell lines. CONCLUSION MsTI could be an useful agent for the potentiation of cisplatin-mediated cancer treatment.

Abstract
Low-dose aprotinin inhibits hyperfibrinolysis in cardiac surgery. However, excessive postoperative bleeding and increased fibrinolysis may occur despite low dose-aprotinin administration. We investigated (i) whether fibrinolytic activity significantly rises under low-dose aprotinin administration, and (ii) whether this is associated with excessive postoperative bleeding (> or = 1000 ml/24 h). In a prospective single-blind trial, 120 consecutive patients were randomized to receive 280 mg aprotinin or no aprotinin before skin incision. D-dimer levels increased significantly to the end of surgery, reaching higher levels in the control group. The risk for excessive bleeding was lower in the aprotinin group (12 versus 37%, = 0.001). Fifteen minutes after heparin reversal, patients were at risk for excessive bleeding, when enhanced fibrinolysis was documented (aprotinin group, D-dimer > or = 1.0 micro g/ml, odds ratio = 9.1, = 0.047; control group, D-dimer > or = 3.0 micro g/ml, odds ratio = 4.6, = 0.014). Ninety-seven per cent of the aprotinin group and 81% of control group patients had no excessive bleeding when the D-dimer plasma level was below these values. We conclude that (i) fibrinolytic activity significantly rises under low-dose aprotinin administration, and (ii) plasma D-dimer levels at end of surgery may help to identify patients who are unlikely to develop excessive postoperative bleeding.

Abstract
OBJECTIVE To study the interaction of antifungal drugs in topical therapy. MATERIALS AND METHODS Local therapy of Candida vaginitis with drugs alone and in combination was examined in a murine model. Zeamatin, a natural plant-derived antifungal protein, was tested alone and in combination with an azole, clotrimazole or nikkomycin Z, a chitin synthase inhibitor. RESULTS Whereas alone, zeamatin was ineffective, nikkomycin Z was effective only when dosed multiple times per day, and clotrimazole efficacy was variable when administered in experimental vehicles (unlike the complex and undefined commercial preparation), zeamatin enhanced the efficacy of either of the other two drugs when they were given in combination. CONCLUSION Drug interactions between novel drugs with unique mechanisms of action should be explored further, and may lead to more potent regimens.

Abstract
BACKGROUND More effective therapy is needed for the treatment of Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). The clinical efficacy of intravenous ulinastatin therapy was investigated in 3 Japanese pediatric patients with SJS or TEN. METHODS Ulinastatin was given to 1 pediatric SJS patient and 2 pediatric TEN patients within 7 days (patient 1; SJS), 6 days (patient 2; TEN), or 4 days (patient 3; TEN) after the onset of the skin rash. Ulinastatin was administered intravenously at a dose of 7,500 U/kg/day (maximum dose: 300,000 U/day). No corticosteroids were given. After the skin lesions resolved, the ulinastatin dose was reduced to between 2,500 and 5,000 U/kg/day as maintenance therapy and then the drug was withdrawn. RESULTS Erythema, fatigue, and fever improved within 12-36 h of starting the ulinastatin infusion, and the skin lesions resolved completely after 4-7 days of ulinastatin therapy. None of the patients had cutaneous or ocular sequelae. No patient developed secondary infection or relapse and ulinastatin therapy caused no side effects. CONCLUSION Ulinastatin dramatically reduced the febrile period with no adverse effects and was very safe in this study. Ulinastatin appears to be a useful and effective therapy for controlling SJS and TEN without sequelae.

Abstract
Newly synthesised starch-g-poly(acrylic acid) copolymers and starch/poly(acrylic acid) mixtures were evaluated for their in vitro inhibition potency towards the proteolytic enzyme trypsin. Their Ca2+ and Zn2+ binding capacity was measured. Carbopol 934P was used as reference polymer. Starch-g-poly(acrylic acid) copolymers were prepared by chemical grafting and 60Co irradiation, the starch/poly(acrylic acid) mixtures by freeze-drying. The influence of preparation method, the ratio starch:acrylic acid, the neutralisation degree and for the freeze-dried polymers the influence of heat treatment after freeze-drying was investigated. All freeze-dried polymers showed a higher inhibition factor (IF) than the chemically grafted and 60Co irradiated starches, which all showed significantly lower IF than Carbopol 934P. The heat treated freeze-dried polymer Amioca/poly(acrylic acid) (1:1) showed a significantly higher IF than the reference polymer (Mann-Whitney test, p<0.05). The Ca2+ and Zn2+ binding capacity of all chemically grafted starches was much lower than for Carbopol 934P. Only the 60Co irradiated starches and freeze-dried polymers with ratio 1:3 approached the binding capacity of the reference polymer. The freeze-dried polymers showed the highest proteolytic enzyme inhibition potency. Freeze-drying and 60Co irradiation could result in the highest ion binding capacity. This combination of proteolytic enzyme inhibition activity and ion binding capacity makes these polymers hopeful excipients for successful oral peptide delivery.

Abstract
Severe alcoholic hepatitis (SAH) is not simply a disease of the liver, but it also causes infection and multiple organ failure, and therefore carries an extremely poor prognosis. We report the successful treatment of two patients with SAH. Case 1: The patient was a 55-year-old man. He was a heavy drinker whose alcohol intake had increased for some 3 years to 1.8 L sake a day. Slight clouding of consciousness, fever, and jaundice were evident on his admission to our hospital. Laboratory data showed leukocytosis with a predominance of polymorphonuclear leukocytes, and a decline in coagulability. He tested negative for various hepatitis virus markers. With the diagnosis of SAH made, steroid pulse therapy and bilirubin adsorption therapy were administered. The jaundice improved and the interleukin-8 (IL-8) level decreased. Continuous intravenous infusion of urinastarine (Miraclid) normalized the granulocyte elastase level. Improvement was also seen in coagulability, ascites, icterus and consciousness. Case 2: The patient was a 49-year-old man. He was a heavy drinker whose alcohol intake had increased for 1 month. Fever, jaundice, ascites, and mild disturbance of consciousness were evident at the time of admission. Examination on admission diagnosed SAH. Bilirubin adsorption and continuous intravenous infusion of urinastarine were initiated. As a result, circulating IL-8 level was decreased and coagulability was improved. Therapy for granulocytic hyperelastasemia and hypercytokinemia supervening on SAH is a new effective approach on improvement in the disease.

Abstract
We examined whether the lung injury produced in rats by intraperitoneal injection of the superantigen, staphylococcal enterotoxin B (SEB), could be inhibited by intravenous preadministration of human urinary trypsin inhibitor (UTI), which exhibits multipotent inhibitory effects on serine proteinases such as plasmin, chymotrypsin, or human leukocyte elastase or cathepsin G, since preliminary experiments showed the ability of UTI to bind lipopolysaccharides and bacterial toxins. For ligand blotting analysis, four kinds of toxins were run on a slab gel and the binding of UTI to the toxins was visualized by immunoblotting. Lung tissue from 26 rats was used for immunohistochemistry using a mouse antirat CD 45 mAb and an antirat macrophage mAb. Lung tissue from 31 rats was used for measurement of myeloperoxidase activity before and after intraperitoneal injection of SEB, after infusion of PBS, UTI, PBS-SEB or UTI-SEB combination. Ten of the 26 rats described above were used for electron microscopy. Rat sera were used for measurement of TNF-alpha. Statistical analysis was performed using the Mann-Whitney U-test. Intraperitoneal injection of SEB caused an increase in the number of punctate areas of haemorrhage on the surface of the lung with time, and histological examination revealed lung injuries with different extents, vasculitis where inflammatory cells were concentrated, and infiltration of numbers of eosinophils into the alveolar septa. However, preadministration of UTI for rats markedly attenuated lung injury and vasculitis induced by intraperitoneal injection of SEB. This revealed, from a marked reduction in the number of inflammatory cells and the extent of injury, a marked inhibition of serum TNF-alpha production and reduction of myeloperoxidase content of rat lungs compared to controls. UTI may have defensive effects to infection by suppressing the early responses of stimulated cells to activated stimulus such as SEB as well as the release of stimulant-mediated cytokines via trapping of bacterial toxins.

Abstract
AIM The objective of this study was to examine the effects of perioperative administration of ulinastatin, or urinary trypsin inhibitor (UTI), on inflammatory cytokines and acute-phase proteins induced by inflammatory cytokines in patients who had undergone hepatic resection. METHOD Twenty patients admitted to the hospital for hepatic resection were equally randomized to one of two groups: the UTI group, those who were administered perioperative UTI, and the control group. RESULTS The UTI group had no adverse effects from using UTI. Production of serum interleukin-6 (IL-6) tended to be attenuated in the UTI group when compared with the control group. Moreover, the UTI group had significantly decreased positive acute-phase C-reactive protein (p < 0.05) and significantly increased negative acute-phase protein prealbumin and retinol-binding protein (p < 0.05). Serum IL-6 levels significantly correlated with serum C-reactive protein levels on postoperative day 1 (r = 0.70, p < 0.01). CONCLUSION These results suggest that perioperative administration of UTI might deserve further assessment for use in modulating acute-phase responses without adverse effects in patients who have undergone hepatic resection.

Abstract
A new approach to overcome the degradation of insulin by proteolytic enzymes and its targeting to the blood through the digestive apparatus was developed. The approach is based on the immobilization of insulin into the polymeric hydrogel which is modified by ovomucoid--glycoprotein, inhibitor of proteolytic enzymes. Oral administration of this system to rabbits and rats, (in contrast to the hydrogels modified by proteolytic enzymes inhibitors without polysaccharide part), statistically significantly lowered blood glucose level.

Abstract
Two children with influenza A-related encephalopathy were treated with a combination of mild hypothermia (deep body temperature of the forehead: 35 degrees C) and anticytokine agents (high-dose methylprednisolone and ulinastatin), while receiving amantadine. One of the cases exhibited acute necrotizing encephalopathy on computed tomography (CT). Although no severe complications occurred, correctable hypokalemia and hyperglycemia occurred in both cases. Both patients recovered without any neurological sequelae. Our therapeutic protocol appears to be effective for managing influenza A-related encephalopathy.

Abstract
OBJECTIVE A systemic inflammatory response after open-heart surgery using cardiopulmonary bypass may be responsible for postoperative organ dysfunction. Ulinastatin, a protease inhibitor, plays an important role in host defense under periods of stress. METHODS We studied the efficacy of ulinastatin on changes in acute-phase reactive substances during and after open-heart surgery. Patients undergoing open-heart surgery were divided into an ulinastatin group (Group U) and a control group (Group C). In Group U, we introduced 600,000 units of ulinastatin into a priming solution for cardiopulmonary bypass, 300,000 units into a cardiopulmonary bypass circuit at the removal of aortic cross-clamping, and 300,000 units a day for 5 days following surgery. RESULTS Immediately after cardiopulmonary bypass, alpha 1-antitrypsin levels decreased significantly in both groups, and increased significantly on the second day after surgery. Ulinastatin levels decreased after cardiopulmonary bypass in Group C. Significantly high levels of ulinastatin were obtained in Group U. Interleukin-6, interleukin-8, and polymorphonuclear elastase were markedly induced, and high levels of plasma concentration continued for several days after surgery. At all sample points, these concentrations in Group U tended to be lower than those in Group C. A significantly positive correlation was seen between the maximum levels of interleukin-8 and polymorphonuclear elastase, but these cytokine and polymorphonuclear elastase levels did not correlate with parameters such as the duration of anesthesia, surgery, cardiopulmonary bypass, or aortic cross-clamping. CONCLUSIONS Our study suggests that high-dose ulinastatin administration to maintain a sufficient concentration of circulating protease inhibitors may suppress overinduction of cytokines and polymorphonuclear elastase in open-heart surgery.

Abstract
BACKGROUND The physiologic significance of milk-borne hormones and growth factors for internal organs of suckling animals is poorly understood. In this study the significance of milk-borne insulin was evaluated, as well as its combination with trypsin inhibitor, and its role in the development of pancreatic digestive capacity at the time of weaning was investigated. METHODS Experiments were performed using insulin-deficient milk formula (standard formula), insulin (20 ng/ml) formula, or insulin with trypsin inhibitor (1 U/ml) formula by a rat artificial-rearing technique. RESULTS In 17-day-old rats administered standard formula, the plasma insulin level was as low as that in 14-day-old rats. When insulin-trypsin inhibitor formula was administered to rat pups, the plasma insulin level was significantly higher than those in rats given standard or insulin formula. In rats artificially reared on standard formula, the usual developmental increases in pancreatic amylase activity and plasma insulin concentration at the beginning of weaning did not occur. Insulin formula elevated the pups' plasma insulin concentration and amylase activity at the onset of weaning but not to the levels observed in mother-reared rats. In rats reared on insulin-trypsin inhibitor formula, the developmental increases in the plasma insulin concentration and amylase activity observed in mother-reared rats were induced. CONCLUSIONS The present study demonstrates the necessity of milk-borne insulin for the development of pancreatic amylase during the weaning period.
