Abstract
AIMS The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation. METHODS AND RESULTS Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (in-hospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, pre-hospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin. CONCLUSION The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality.

Abstract
BACKGROUND Pancreatic cystic lesions (PCLs) are common in clinical practice. The accurate classification and diagnosis of these lesions are crucial to avoid unnecessary treatment of benign lesions and missed opportunities for early treatment of potentially malignant lesions.
AIM To evaluate the role of cyst fluid analysis of different tumor markers such as cancer antigens [e.g., cancer antigen (CA)19-9, CA72-4], carcinoembryonic antigen (CEA), serine protease inhibitor Kazal-type 1 (SPINK1), interleukin 1 beta (IL1-β), vascular endothelial growth factor A (VEGF-A), and prostaglandin E2 (PGE2)], amylase, and mucin stain in diagnosing pancreatic cysts and differentiating malignant from benign lesions.
METHODS This study included 76 patients diagnosed with PCLs using different imaging modalities. All patients underwent endoscopic ultrasound (EUS) and EUS-fine needle aspiration (EUS-FNA) for characterization and sampling of different PCLs.
RESULTS The mean age of studied patients was 47.4 ± 11.4 years, with a slight female predominance (59.2%). Mucin stain showed high statistical significance in predicting malignancy with a sensitivity of 87.1% and specificity of 95.56%. It also showed a positive predictive value and negative predictive value of 93.1% and 91.49%, respectively (P < 0.001). We found that positive mucin stain, cyst fluid glucose, SPINK1, amylase, and CEA levels had high statistical significance (P < 0.0001). In contrast, IL-1β, CA 72-4, VEGF-A, VEGFR2, and PGE2 did not show any statistical significance. Univariate regression analysis for prediction of malignancy in PCLs showed a statistically significant positive correlation with mural nodules, lymph nodes, cyst diameter, mucin stain, and cyst fluid CEA. Meanwhile, logistic multivariable regression analysis proved that mural nodules, mucin stain, and SPINK1 were independent predictors of malignancy in cystic pancreatic lesions.
CONCLUSION EUS examination of cyst morphology with cytopathological analysis and cyst fluid analysis could improve the differentiation between malignant and benign pancreatic cysts. Also, CEA, glucose, and SPINK1 could be used as promising markers to predict malignant pancreatic cysts.

Abstract
AIM To assess the value of the ratio of signal intensities at high and low b-values (b800/b0 ratio) during diffusion-weighted imaging (DWI) for gallbladder cancer diagnosis. MATERIALS AND METHODS All patients presenting with suspicious gallbladder lesions between January 2011 and December 2016 who underwent DWI and histopathological diagnoses of the lesions were assessed. RESULTS Thirty-two patients (24 men, eight women) were identified. Eighteen patients had benign gallbladder lesions while 14 had malignant lesions. The mean apparent diffusion coefficient (ADC) value was 1.62 (±0.57)×10-3 mm2/s for benign cases and 1.27 (±0.39)×10-3 mm2/s for malignant cases; this difference was not significant (p=0.0773). The mean b800/b0 ratio was 0.31 (±0.19) for benign cases and 0.48 (±0.13) for malignant cases; this difference was significant (p=0.007). The ROC curve for b800/b0 had an AUC of 0.782 (95% confidence interval [CI]: 0.616-0.947) with a sensitivity and specificity of 85.7% and 72.2%, respectively, at a cut-off point of 0.33. CONCLUSION The b800/b0 ratio can help differentiate benign and malignant gallbladder lesions and may be more reliable than ADC values in quantitative DWI assessments.

Abstract
BACKGROUND/AIM Recently, endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) has emerged using a self-expandable metallic stent (SEMS). The aim of the study was to evaluate the long-term outcomes of this procedure. In addition, the efficacy and safety of EUS-GBD with SEMS were assessed. PATIENTS AND METHODS Thirteen consecutive patients who underwent EUS-GBD for acute cholecystitis between February 2014 and September 2016 were included in this retrospective study. EUS-GBD was performed under the guidance of EUS and fluoroscopy, through puncturing the gallbladder with a needle, inserting a guidewire, dilating the puncture hole, and placing a SEMS. RESULTS The rates of technical success, functional success, and adverse events were 100%, 92.3% and 7.7%, respectively. The median procedure time was 26.9 min (range 19-42 min). The median follow-up time was 240 days (range 14-945 days) and during this follow-up period recurrence of cholecystitis was observed in one patient (7.7%). CONCLUSION EUS-GBD with a SEMS is a possible alternative treatment for acute cholecystitis in high surgical risk patients. Long-term outcomes after EUS-GBD were promising.

Abstract
Platelets are considered to have important functions in inflammatory processes and as actors in the innate immunity. Several studies have shown associations between cardiovascular disease and periodontitis, where the oral anaerobic pathogen Porphyromonas gingivalis has a prominent role in modulating the immune response. Porphyromonas gingivalis has been found in atherosclerotic plaques, indicating spreading of the pathogen via the circulation, with an ability to interact with and activate platelets via e.g. Toll-like receptors (TLR) and protease-activated receptors. We aimed to evaluate how the cysteine proteases, gingipains, of P. gingivalis affect platelets in terms of activation and chemokine secretion, and to further investigate the mechanisms of platelet-bacteria interaction. This study shows that primary features of platelet activation, i.e. changes in intracellular free calcium and aggregation, are affected by P. gingivalis and that arg-gingipains are of great importance for the ability of the bacterium to activate platelets. The P. gingivalis induced a release of the chemokine RANTES, however, to a much lower extent compared with the TLR2/1-agonist Pam3 CSK4 , which evoked a time-dependent release of the chemokine. Interestingly, the TLR2/1-evoked response was abolished by a following addition of viable P. gingivalis wild-types and gingipain mutants, showing that both Rgp and Kgp cleave the secreted chemokine. We also demonstrate that Pam3 CSK4 -stimulated platelets release migration inhibitory factor and plasminogen activator inhibitor-1, and that also these responses were antagonized by P. gingivalis. These results supports immune-modulatory activities of P. gingivalis and further clarify platelets as active players in innate immunity and in sensing bacterial infections, and as target cells in inflammatory reactions induced by P. gingivalis infection.

Abstract
BACKGROUND Data are scarce on ocular complications in Egyptian patients with chronic hepatitis C treated with pegylated interferon and ribavirin therapy. The aim of this study was to investigate the development of retinal lesions induced by interferon therapy for chronic hepatitis C. METHODS We prospectively analyzed 84 patients with chronic hepatitis C (total 168 eyes), who underwent combination pegylated interferon and ribavirin therapy for 48 weeks. Visual acuity, color vision, and visual field were measured, and a fundus assessment was made at baseline, at 12, 24, and 48 weeks post the commencement of treatment, and at follow-up, 1 month after treatment. Past medical and ocular histories, visual symptoms, and the results of a full ophthalmologic assessment were recorded for each patient. RESULTS Twenty-two patients (26%) developed retinopathy. Retinal hemorrhage was observed in eight patients. Four patients complained of visual disturbance. Retinopathy disappeared in 16 patients (73%) despite the continuation of combination therapy. However, retinopathy persisted in six patients with retinal hemorrhage and three of them stopped treatment. A comparison of the clinical backgrounds between the patients with and without retinopathy showed no significant differences with regard to gender, HCV RNA level, white blood cell count, platelet count, hemoglobin level, or fibrosis score. However patients with retinopathy were of older age, had a higher prevalence of hypertension and diabetes mellitus, and more often did not respond to therapy. Multiple logistic regression analysis revealed that hypertension and diabetes were factors predicting retinopathy. CONCLUSION Retinopathy associated with interferon α-2a and ribavirin combination therapy tends to develop in patients of older age with hypertension and diabetes.

Abstract
INTRODUCTION Vascular complications (VC) after liver transplantation (OLT) are one of the most feared problems that frequently result in graft and patient loss. Herein we have reported our experience with VC after either deceased donor liver transplantation (DDLT) or living donor liver transplantation (LDLT). PATIENTS AND METHODS Between April 2001 and September 2009, we performed 224 OLT: 155 DDLT and 69 LDLT. The overall male/female ratio was 136/88 and the adult/pediatric ratio was 208/16. We retrospectively identified and analyzed vascular complications in both groups. RESULTS In the DDLT group, 11/155 recipients (7%) suffered vascular complications; hepatic artery thrombosis (HAT; n=5; 3.2%), portal vein thrombosis occurred (n=4; 2.6%); hepatic vein stenosis (n=1; 0.6%), and severe postoperative bleeding due to a slipped splenic artery ligature (n=1, 0.6%). In the DDLT group, 4/11 (36.4%) patients died as a direct result of the vascular complications. In the LDLT group, 9/69 recipients (13%) suffered vascular complications: HAT (n=3; 4.3%), portal vein problems (n=5; 7.2%), and hepatic vein stenosis (n=1; 1.5%). Among LDLT, 3/9 (33.3%) patients died as a direct result of the vascular complications. In both groups vascular complications were associated with poorer patient and graft survival. CONCLUSIONS In our experience, the incidence of vascular complications was significantly higher among the LDLT group compared with the DDLT group. Vascular complications were associated with poorer graft and patient survival rates in both groups.

Abstract
Long waiting list times in liver transplant programs in Saudi Arabia and unavailability of deceased donor transplantation in Egypt have led several patients to seek transplantation in China. All patients who received transplants in China and followed in three centers from January 2003-January 2007 were included. All patients' charts were reviewed. Mortality and morbidity were compared to those transplanted in King Faisal Specialist Hospital & Research Centre (KFSH&RC) during the same period. Seventy-four adult patients were included (46 Saudi nationals; 28 Egyptians). One-year and 3-year cumulative patient survival rates were 83% and 62%, respectively compared to 92% and 84% in KFSH&RC. One-year and 3-year cumulative graft survival rates were 81% and 59%, respectively compared to 90% and 84% in KFSH&RC. Compared to KFSH&RC, the incidence of complications was significantly higher especially biliary complications, sepsis, metastasis and acquired HBV infection posttransplant. Requirements of postoperative interventions and hospital admissions were also significantly greater. Our data show high mortality and morbidity rates in Saudi and Egyptian patients receiving transplants in China. This could be related to more liberal selection criteria, use of donation after cardiac death (DCD) donors or possibly more limited posttransplant care.

Abstract
OBJECTIVE To report our experience with dermatological complications after both deceased donor liver transplantation (DDLT) and living-donor liver transplantation (LDLT). PATIENTS AND METHODS Between April 2001 and November 2006, a total of 116 liver transplantation (LT) procedures were performed (73 DDLTs and 43 LDLTs) in 112 patients (4 re-transplants). Posttransplant dermatological problems were recorded. RESULTS Among 112 OLT recipients, 14 patients (12.5%) experienced dermatologic problems: epidermolysis bullosa acquisita in one patient, which was self-limiting; graft-versus-host-disease in one patient treated with high-dose steroids; Kaposi sarcoma in one patient treated with surgical excision and conversion to sirolimus-based immunosuppression; drug-induced cutaneous vasculitis with deep thigh ulcer formation treated by drug discontinuation and surgical excision of the ulcer; herpes zoster in one patient treated with intravenous antiviral therapy; herpes simplex in two patients treated with local antiviral cream; cyclosporine-induced gingival hyperplasia treated with conversion to FK506; cyclosporine-induced hypertrichosis treated with conversion to FK506; steroid-induced skin hyperpigmentation in one patient treated with steroid withdrawal; hypomagnesemia-induced hair loss treated with daily oral magnesium supplement; pressure-induced alopecia areata in two patients that was self-limiting; and finally, one patient with a pressure-induced heel ulcer that was treated conservatively. In 8 of 14 patients (57%) who suffered from dermatologic problems, the complication was primarily related to immunosuppressive drugs. CONCLUSIONS In our experience, dermatologic complications following LT are not uncommon and usually related to immunosuppressive therapy. Most complications could be prevented by optimizing immunosuppression. The majority of complications were easily managed by simple adjustment of immunosuppression.

Abstract
OBJECTIVE To present our experience with deceased donor liver transplantation (DDLT) and living-donor liver transplantation (LDLT) for autoimmune hepatitis (AIH). PATIENTS AND METHOD Between April 2001 and November 2006, a total of 116 LT procedures were performed (73 DDLTs and 43 LDLTs) in 112 patients (4 retransplants). Of the 112 recipients, 16 patients (14.3%) were transplanted for AIH (15 DDLTs and 1 LDLT). All recipients received FK506- and steroid-based immunosuppressive regimens. RESULTS The male/female ratio was 3/13, median age was 22 years (range, 15 to 35), and the median MELD score was 25 (range, 11 to 40). Arterial reconstruction was needed in four DDLTs due to severe steroid-induced angiopathy. After a median follow-up period of 530 days (range, 11 to 2016), the overall patient and graft survival rates were 93.8%. Only one patient died following LDLT due to primary graft nonfunction. Histopathologic recurrence was seen in three patients (18.7%) and was successfully treated by optimizing immunosuppression. Markedly elevated serum CA19-9 levels (median, 1069; range, 217 to 2855) was seen in four patients (28%), malignancy was ruled out and all patients normalized serum CA19-9 levels within the first 3 months posttransplant. Steroids withdrawal failed in all recipients and was always accompanied with almost immediate elevation of liver enzymes. CONCLUSIONS In our experience, LT for AIH shows excellent long-term outcomes, patients are usually young women who present with acute deterioration and high MELD scores, and usually require long-term steroids to prevent rejection and disease recurrence. Some patients have markedly high CA19-9 in absence of malignancy. Some patients also have severe steroid-induced hepatic artery angiopathy necessitating arterial reconstruction during the transplant surgery.

Abstract
OBJECTIVES To objectively evaluate outcomes after living donor hepatectomy. PATIENTS AND METHOD Between November 2002 and August 2006, a total of 44 procedures were performed (35 right, eight left, and one aborted after surgical incision). The Clavien classification was used to record surgical complications as follows: grade I, alterations from the ideal postoperative course not requiring specialized pharmacological or surgical treatment; grade II, complications requiring specialized pharmacological treatment, blood transfusion, or total parental nutrition; grade III-a, complications requiring invasive intervention without general anesthesia; Grade III-b, requires general anesthesia; Grade IV-a, single organ dysfunction; Grade IV-b, multiorgan dysfunction; grade V, death; The suffix "d" indicated disability. In this study, grades I and II complications were considered minor, while grades III and V and any lasting disability, serious complications. RESULTS Male/female ratio was 34/10; median age was 25 years (range, 18 to 42); median hospital stay was 6 days (range, 4 to 14); and only two donors required intraoperative blood transfusion. After a median follow-up of 529 days (range, 8 to 1354), a total of 28 morbidities were encountered in 17 donors (38.6%), including nine donors (20.4%) who had serious complications. Among the 28 donor morbidities, 18 were grade I complications; three were grade III-a complications; five were grade III-b complications; and two were grade IV-a complications. No death was encountered in our experience. CONCLUSIONS In our experience, donor hepatectomy was not an entirely safe procedure; therefore, extreme care should always be given by the transplant teams to living donors to avoid any distressing morbidity or even, the less likely but more catastrophic, mortality.

Abstract
INTRODUCTION Heme-Oxygenase-1 catalyzes hemoglobin into bilirubin, iron, and carbon monoxide, a well known vasodilator. Heme-Oxygenase-1 expression and carbon monoxide production as measured by blood carboxyhemoglobin levels, increase in end stage liver disease patients. We hypothesized that there may be a correlation between carboxyhemoglobin level and early graft function in patients undergoing liver transplant surgeries. METHODS In a descriptive retrospective study, 39 patients who underwent liver transplantation between the year 2005 and 2006 at KFSH&RC, are included in the study. All patients received general anesthesia with isoflurane in 50% oxygen and air. Levels of oxyhemoglobin, carboxyhemoglobin and methemoglobin concentration in percentage were recorded at preoperative time, anhepatic phase, end of surgery, ICU admission and 24 hr after surgery. The level of lactic acid, prothrombin time (PT), partial thrombin time (PTT), serum total bilirubin and ammonia were also recorded at ICU admission and 24 hr after surgery. The numbers of blood units transfused were recorded. RESULTS 39 patients were included in the study with 13/39 for living donor liver transplant (LDLT) compared to 26/39 patients scheduled for deceased donor liver transplant (DDLT). The mean age was 35.9 +/- 16.9 years while the mean body weight was 60.3 +/- 20.9 Kg. Female to male ratio was 21/18. The median packed red blood cell (PRBC) units was 4 (Rang 0-40). There was a significant increase in carboxyhemoglobin level during the anhepatic phase, end of surgery and on ICU admission compared with preoperative value (p<0.005). However, there was insignificant changes in methemoglobin level and significant decrease in oxyhemoglobin levels throughout the study period compared to the preoperative value (p<0.005). The changes in carboxyhemoglobin level on ICU admission and 24 hrs postoperatively were positively correlated with the changes in serum total bilirubin and prothrombin time (R = 0.35, 0.382, 0.325 and 0.31) respectively p<0.05) but not with the changes in serum lactic acid. The same strong correlation was found when analysing LDLT and DDLT patients separately between carboxyhemoglobin concentration and PT and total bilirubin while still the correlation with lactic acid was weak. There was no correlation between average perioperative carboxyhemoglobin concentration during different timing of measurements and average units of transfused blood (R = -0.02) p>0.05. CONCLUSION The changes in carboxyhemoglobin level significantly correlate with the Changes in graft functions particularly prothrombin time and serum total bilirubin and may be used as an early, rapid and simple test for early evaluation of graft function.

Abstract
BACKGROUND Accurate estimation of graft volume is crucial to avoid small-for-size syndrome following adult-to-adult living donor liver transplantation AALDLT). Herein, we combined radiological and mathematical approaches for preoperative assessment of right graft volume. METHODS The right graft volume was preoperatively estimated in 31 live donors using two methods: first, the radiological graft volume (RGV) by computed tomography (CT) volumetry and second, a calculated graft volume (CGV) obtained by multiplying the standard liver volume by the percentage of the right graft volume (given by CT). Both methods were compared to the actual graft volume (AGV) measured during surgery. The graft recipient weight ratio (GRWR) was also calculated using all three volumes (RGV, CGV, and AGV). Lin's concordance correlation coefficient (CCC) was used to assess the agreement between AGV and both RGV and CGV. This was repeated using the GRWR measurements. RESULTS The mean percentage of right graft volume was 62.4% (range, 55%-68%; SD +/- 3.27%). The CCC between AGV and RGV versus CGV was 0.38 and 0.66, respectively. The CCC between GRWR using AGV and RGV versus CGV was 0.63 and 0.88, respectively (P < .05). According to the Landis and Kock benchmark, the CGV correlated better with AGV when compared to RGV. The better correlation became even more apparent when applied to GRWR. CONCLUSION In our experience, CGV showed a better correlation with AGV compared with the RGV. Using CGV in conjunction with RGV may be of value for a more accurate estimation of right graft volume for AALDLT.

Abstract
INTRODUCTION Organ shortage remains the main limiting factor for expanding liver transplantation (LT) in Saudi Arabia. Therefore, living donor liver transplantation (LDLT) was recently undertaken by our team at King Faisal Specialist Hospital and Research Center (KFSH&RC), in an effort to meet the increasing demand for LT in Saudi Arabia. OBJECTIVE Analysis of donors assessed for LDLT at KFSH&RC. METHODS Between September 2002 and May 2003, 39 potential donors were assessed for LDLT. First- or second-degree relationship to the recipient was an essential precondition. Assessment included biochemical testing, radiological studies (computed tomography: magnetic resonance angiography, magnetic resonance cholangiography), and thorough psychosocial analysis. Liver biopsy and hepatic angiogram was performed in some but not all donors. RESULTS Male:female ratio was 28:11. Median age was 27 (18 to 34). Of 39 potential donors, only three underwent LDLT. The remaining 36 were rejected for different reasons including: psychosocial in 8 (20.5%), fatty liver in 7 (17.9%), recipient issues in 6 (15.4%), refusal after initial approval in 3 (7.7%), unfavorable anatomy in 2 (5.1%), inadequate liver volume in 2 (5.1%), abnormal liver functions in 2 (5.1%), hepatitis C virus in 2 (5.1%), liver pathology in 1 (2.6%), and other medical concerns in remaining 3 donors (7.7%). CONCLUSION In Saudi Arabia, donor availability as well as recipient characteristics may limit the value of LDLT in overcoming organ shortage. Therefore, efforts should be directed to improve the number and quality of available cadaveric organs. Until then, LDLT may be the only way forward to save patients from dying on the waiting list.

Abstract
Organ transplantation has been widely accepted as a solution for end-stage organ failure. The limitation has been organ shortage. The intensivist plays a major role in the different stages of the donation process. This study investigated the knowledge and attitude toward organ donation and transplantation amongst intensivists in the major hospitals of Riyadh. The study was conducted in June 2002. Twenty-two intensivists in the intensive care units (ICUs)of 4 hospitals in Riyadh participated in the study. A questionnaire was distributed concerning knowledge and attitude on donation and transplantation. The information was tabulated and analyzed. Only 50% appreciated the high success rate of modern organ transplantation. One fourth did not know of the role of the Saudi Center for Organ Transplantation (SCOT). Most of the intensivists knew the Islamic view on transplantation. Many would be willing to allow donation from a deceased relative. However, only 13% carry donation cards. Most participants believed that the organ shortage was mainly due to family refusal to donate. Intensivists need to have better insight into the obstacles to donation that can be solved at the level of the hospital and the ICUs. Moreover, the communication gap between ICUs and SCOT needs to be bridged to optimize the use of all potential donors.

Abstract
INTRODUCTION Postoperative alopecia areata (PAA) following surgery has been reported, especially after certain gynecologic and cardiac procedures; however, no cases have been reported after liver transplant (LT). Localized pressure associated with prolonged anesthesia is usually blamed. Herein we report a few cases of PAA encountered especially in relation to LT procedures. OBJECTIVE To report our PAA cases, identifying possible contributing risk factors. METHODS Between April 2001 and May 2003 the data on eight PAA cases were analyzed for age, sex, type of surgery, duration of anesthesia, type of head support, periods of hypotension, and psychiatric comorbidity. RESULTS Median age of affected patients was 27 years (10 to 44) and the male/female ratio 3/5. The type of surgery included: two LT recipients, two LT donors, three cardiac valve replacements, and one coronary bypass surgery. Median anesthesia time was 6 hours (3 to 12). Sponge or jelly donut was used for head support with frequent change of its position as per protocol. There were no significant periods of hypotension. Surprisingly, almost all patients had a documented psychiatric comorbidity, mainly anxiety, adjustment/adaptation, or mood disorders. CONCLUSIONS PAA is a rare complication following certain surgeries including both donor and recipient LT procedures. Although pressure-induced ischemia is the most likely etiological factor, we believe that psychiatric comorbidity plays a major role in its development. Therefore, preoperative thorough psychiatric counseling in addition to frequent intraoperative head repositioning will help to avoid this minor but distressing postoperative complication.

Abstract
A modified hydrophobic and organophilic pillared clay (CTAC-TiH-montm) was prepared by exchanging some Ti polymeric cations into the interlamellar space of one Algerian montmorillonite (montm) and then by co-adsorption of some surfactant molecules such as cetyltrimethylammonium chloride (CTAC). These new materials were used in adsorption of an anionic textile dye: Sulfacid brilliant pink (SAP). According to adsorption isotherms, the organic modification of Ti-montmorillonite clay by CTAC surfactant increases the amount of textile dye fixed to more than 1000 mg g(-1). The adsorption experiments showed that a ratio of 3 mmol of CTAC per g of clay and an acidic medium (pH = 4) were the optimal parameters necessary to obtain good adsorption uptake and colourless treated solutions. A comparative study proved the high adsorption capacity of the synthesised adsorbents; they can thus be considered as powerful competitors to activated carbon in the treatment of aqueous textile plants and industry effluents.

Abstract
The first part of this work considers the preparing of the adsorbent type Montm-FeOH-CTAC. After purification of two types Algerian bentonites (Maghnia and Mostaghanem) and preparation of cationic polyhydroxy ferric solution, we have optimized following parameters: CTAC/Montm.-FeOH = 7 mmol.g-1 and pH = 3.4, in order to obtain the adsorbent with maximum uptake of PCP. The study of the different experimental equilibrium isotherms showed clearly the high efficiency of these new adsorbents toward PCP, with significant quantities adsorbed especially onto Maghnia samples in acidic environment. Using two mathematical models Langmuir and Freundlich was found to be the Freundlich the best fitted. A comparative study of PCP adsorption onto the two modified clays and an activated carbon in the same conditions has been done.

Abstract
BACKGROUND/AIMS Cholyl-lysyl-fluorescein is a fluorescent analogue of the natural bile acid, cholyl glycine. In vivo and in vitro studies showed that this analogue has many biological characteristics similar to cholyl glycine. In this study we analysed cholyl-lysyl-fluorescein plasma clearance in six healthy volunteers as a potential quantitative liver function test. METHODS The compound in water for injection was administered as an i.v. bolus in the dose of 0.02 mg/kg b.w. RESULTS The plasma elimination curve showed rapid, intermediate and slow phases of clearance. Half-life (T1/2 time) for the first (t1/2 1st phase), second (t1/2 2nd phase) and third (t1/2 3rd phase) phases of elimination was 1.7+/-0.9 min, 6.7+/-1.6 min and 68+/-17 min, respectively. Ninety-minute plasma retention (% dose/l plasma) was 2.2%. Cholyl-lysyl-fluorescein volume of distribution and residual fluorescence after 60 min were similar to the data obtained by others for natural or radiolabelled bile acids. In five out of six healthy volunteers a 25-fold higher dose of cholyl-lysyl-fluorescein (0.5 mg/kg b.w.) was injected to estimate the safety margins of the compound. This dose was eliminated at a disappearance rate similar to that of the dose of 0.02 mg/kg b.w. and did not cause any adverse reactions. Serum liver tests measured before and after injection did not change significantly. CONCLUSIONS This study showed that cholyl-lysyl-fluorescein clearance is similar to the clearance of endogenous natural bile acids and may potentially offer a new, dynamic test of liver function.

Abstract
8 different leukosis antigen preparations for immunodiffusion from 6 European countries were examined regarding their suitability for immunoblotting. Emphasis was made on demonstration of immunoreactions at 51 kDa beside reactions at 24 kDa. The whole protein content of the different preparations varied very much. gp 51 could be detected only by monoclonal antibodies at a molecular weight of 53 kDa, in one preparation at 26 kDa. With sera from field or with the European reference serum E4 none or only weak reactions could be observed at these molecular weights. All antigen preparations contained bovine IgG that is divided in L- and H-chains by SDS-electrophoresis under reducing conditions. These single chains reacted also with anti-bovine-IgG-biotin conjugate und disturbed the detection of the leukosis specific reactions. The bovine IgG could be removed by a Protein-G-column. One of all tested leukosis antigens, which are prepared for immunodiffusion, was suitable for immunoblotting. This antigen preparation contained only few bovine IgG and had strong reactions at 24 kDa. A special antigen preparation for detection of other reliable immunoreactions in the immunoblot has to be developed.

Abstract
Portal venous blood for rinsing out the University of Wisconsin solution (UWs) has the advantages of being a physiological fluid, removing acidotic mesenteric venous blood and perhaps resulting in more stable haemodynamic parameters during reperfusion. A group of 209 consecutive adult OLTs carried out between July 1993 and February 1995 were studied prospectively. The UWs was flushed out with 500 ml portal blood in 95 OLTs (group 1) and with 1.0 L 0.5% dextrose at 37 degrees C in 114 OLTs (group 2). The median day 1 and peak day 1-5 AST levels were significantly elevated in the 5% dextrose group: median 755 (118-11090) vs. 546 (121-6150) IU/I (P = 0.007, Wilcoxon); and median 1095 (159-11090) vs. 744 (157-7870) IU/l (p = 0.008, Wilcoxon), respectively. A median of 5 (0-27) units of blood were transfused in group 1 compared to 4 (0-54) units in group 2 (n.s.). There was no difference in peak bilirubin, lowest day 1-5 PT levels, primary nonfunction, median ITU stay, total inpatient stay and 1-month graft survival between the two groups (89% vs. 88%). Pre-reperfusion blood flush may be associated with less hepatocellular damage, without significant additional blood usage.

Abstract
We investigated the influence of some proteolytic enzymes being present in the digestive canal (pepsin, trypsin, chymotrypsin) on the digestion of porcine FSH-samples by electrophoresis. Trypsin and Chymotrypsin digested the 18-kDa-protein much faster than pepsin, whereas a 67-kDa-protein was much faster digested by Pepsin than by Trypsin or Chymotrypsin. The overall proteolytic effect of Chymotrypsin is small compared with Pepsin and Trypsin. A subsequent digestion with Pepsin, Trypsin and Chymotrypsin led to a complete proteolysis of all proteins being present in the sample.

Abstract
A method for detection of antibodies against the enzootic bovine leukemia virus in single serum and milk samples, as well as in pooled milk samples, is described. After the electrophoretical separation of the antigen proteins with SDS-PAGE, a transfer onto an immobilizing membrane is done, followed by immunodetection based on the reaction of the leukemia virus antibodies with antigen proteins. The antibody-antigen complex is visualized by a second, biotinylated antibody and peroxidase-avidin. This system is developed for verification of ELISA-results in surveillance of official admitted herds free of leukosis. The threshold for positive samples is tested by the European reference serum E-4, Copenhagen, the dilution 1:25,000 is recognized as positive. The detected antigen-antibody reactions are determined by scanning and comparison with the MW-markers.

Abstract
A new method for the fast, reliable and reproducible submicrogram quantitation of proteins separated by different electrophoretic techniques is presented. The method is based on a modified sensitive staining technique using Coomassie Brilliant Blue G-250 in colloidal solution combined with an optimized elution procedure of the bound dye in a 3% w/v solution of sodium dodecyl sulfate followed by photometric determination of dye concentration in the eluate. In addition a new method is provided for background correction, even suitable for gels showing strong background staining. The staining procedure allows the detection of 20 ng depending on the nature of the protein and the separation technique used. Quantitation is linear at least in the range from 50 ng to 10 micrograms and highly reproducible even under non-optimized conditions. The presented method can be applied to sodium dodecyl sulfate-electrophoresis, isoelectric focusing and two-dimensional electrophoresis.

Abstract
A simple and rapid method for the quantitation of proteins separated either by sodium dodecyl sulfate-electrophoresis or by isoelectric focusing in slab gels is presented. The method is based on the solubility of polyacrylamide gels crosslinked with N, N'-1, 2-dihydroxyethylenebisacrylamide (DHEBA) in periodic acid. After electrophoretic separation proteins are stained with Coomassie brilliant blue G-250. DHEBA gels show considerable swelling during the staining and destaining process but can be shrunk to their normal size in a 10% (w/v) solution of ammonium sulfate. Stained bands are cut from the gel and solubilized in periodic acid. During dissolution the dye decolorizes. Protein concentration in the solution is determined by a modified Coomassie dye-binding assay. Quantitation is linear in the range of 100 ng to 5 micrograms and not disturbed by dissolved gel. Separations in N, N'-1, 2-dihydroxyethylenebisacrylamide-crosslinked gels show qualities similar to those in normal crosslinked gels.

Abstract
2-Chloro-1-methylpyridinium iodide is a coupling reagent for peptide synthesis. By its use different peptides were synthesized with protected di- and trifunctional amino acids. While urethan-protected amino acids react free of racemization, the fragment condensation needs N-Hydroxysuccinimide, as shown by the Young test.
