Abstract
The results of surgical treatment of 137 patients, suffering obturation jaundice of non-tumoral etiology, were analyzed. In all the patients the cause of obturation jaundice was choledocholithiasis. Roncoleukin was infused intravenously additionally in a complex of therapy. A degree of hepatic dysfunction was determined, taking into account the cholestasis markers. In 23 patients purulent cholangitis have occurred on background of obturation jaundice. Concentration of cytokins TNF-α, IFN-γ, IL-1, IL-2, IL-4, IL-6, IL-10 in sera were determined, using immunoassay analysis. The cytokins dysbalance severity preoperatively and dynamics of its changes have depended upon the hepatic dysbalance degree and presence of purulent cholangitis; a dysbalance is deeper, when the hepatic dysfunction is higher. Application of pathogenetically substantiated purposeful cytokinotherapy, including roncoleukin, have promoted the cytokins dysbalance elimination and improvement of the patients treatment results.

Abstract
The article analyzed the results of surgical treatment of 137 patients with obstructive jaundice of benign genesis. An immune status was studied in serum in dynamics before surgery. The rates of CD3, CD4, CD8, CD19, Ig A, M, G were determined on the first, third, seventh and fourteenth days after operation. The levels of TNFα, IFNγ, IL-2, IL-6, IL-4, IL-10 were investigated in serum and at the same time TNFα, IL-4, IL-6 were noted in the bile duct and IL-6 - in urine. Obstructive jaundice of cholelithiс genesis is characterized by disbalance of immune and cytokine status. The depth of disbalance depends on the degree of hepatic dysfunction and presence of purulent cholangitis. The directed cytokine therapy by ronkoleykin influenced positively on elimination of disbalance in immune and cytokine status and this therapy improved results of surgery in postoperative period.

Abstract
Immunoglobulin G4 related disease (IgG4-RD) has been recognized since early 2000s as an entity comprising a set of inflammatory diseases with common histopathological features. The disease may affect almost all organs and tissues, and often occurs in a subacute fashion in males over 50 years as a mass or diffuse enlargement of affected organs. The histopathological appearance is characterized by a lymphoplasmacytic infiltration with predominantly IgG4-positive plasma cells and progressive fibrosis. Its clinical and radiological features can make the distinction with a malignancy difficult. The disease responds well to systemic glucocorticoids however with a high rate of recurrence after treatment discontinuation.

Abstract
AIM: To observe the protective effect of glucagon-like peptide-2 (GLP-2) on the intestinal barrier of rats with obstructive jaundice and determine the possible mechanisms of action involved in the protective effect.
METHODS: Thirty-six Sprague-Dawley rats were randomly divided into a sham operation group, an obstructive jaundice group, and a GLP-2 group; each group consisted of 12 rats. The GLP-2 group was treated with GLP-2 after the day of surgery, whereas the other two groups were treated with the same concentration of normal saline. Alanine aminotransferase (ALT), total bilirubin, and endotoxin levels were recorded at 1, 3, 7, 10 and 14 d. Furthermore, on the 14th day, body weight, the wet weight of the small intestine, pathological changes of the small intestine and the immunoglobulin A (IgA) expressed by plasma cells located in the small intestinal lamina propria were recorded for each group.
RESULTS: In the rat model, jaundice was obvious, and the rats’ activity decreased 4-6 d post bile duct ligation. Compared with the sham operation group, the obstructive jaundice group displayed increased yellow staining of abdominal visceral serosa, decreased small intestine wet weight, thinning of the intestinal muscle layer and villi, villous atrophy, uneven height, fusion, partial villous epithelial cell shedding, substantial inflammatory cell infiltration and significantly reduced IgA expression. However, no significant gross changes were noted between the GLP-2 and sham groups. With time, the levels of ALT, endotoxin and bilirubin in the GLP-2 group were significantly increased compared with the sham group (P < 0.01). The increasing levels of the aforementioned markers were more significant in the obstructive jaundice group than in the GLP-2 group (P < 0.01).
CONCLUSION: GLP-2 reduces intestinal mucosal injuries in obstructive jaundice rats, which might be attributed to increased intestinal IgA and reduced bilirubin and endotoxin.

Abstract
Obstructive jaundice (OJ) increases the risk of liver injury and sepsis, leading to increased mortality. Cholestatic liver injury is associated with a downregulation of hepcidin expression levels. In fact, hepcidin has an important antimicrobial effect, especially against Escherichia coli. It is unknown whether supplementing recombinant hepcidin is effective in alleviating cholestasis-induced liver injury and mortality in mice with superimposed sepsis. A mouse model of cholestasis was developed using extrahepatic bile duct ligation for 3 days. In addition, sepsis due to E. coli 0111:B4 lipopolysaccharide (LPS) was induced in the model. The serum levels of total bilirubin, AST, ALT, and LDH and the mRNA levels of IL-1β, TNF-α, and MCP-1 in the liver were significantly higher in the OJ mice receiving LPS than in the sham-operated mice receiving LPS. Compared to the OJ mice receiving LPS, the hepcidin-pretreated OJ mice receiving LPS showed a significant decrease in the above mentioned parameters, as well as a reversal in the downregulation of LC3B-II and upregulation of cleaved caspase-3; this, in turn, led to significantly decreased lethality in 24h. In conclusion, these results indicate that hepcidin pretreatment significantly reduced hepatic proinflammatory cytokine expression and liver injury, leading to reduced early lethality in OJ mice receiving LPS. Enhanced autophagy and reduced apoptosis may account for the protective effects of hepcidin.

Abstract
Autoimmune pancreatitis (ALP) represents a distinct form of chronic pancreatitis initially described in Japan but now reported worldwide. AIP often presents with obstructive jaundice/pancreatic mass as well as pancreatic exocrine and endocrine insufficiency. Histologically, it is characterised by a lymphoplasmacytic infiltrate with fibrosis. The disease responds readily to steroids in 70-80% of cases. Given the absence of unified diagnostic criteria, the diagnosis of AIP proves difficult. In particular, distinguishing ALP from pancreatic or biliary cancer remains a challenging task. In order to avoid unnecessary resections for an otherwise benign and easily treatable condition, it is urgent to refine diagnostic criteria and to reach an international consensus.

Abstract
The authors have studied indices of the humoral immunity with mechanical jaundice of nonneoplastic genesis. Disorders of immune status of patients with bilious ways obturation, which were characterized by concentration increase IgG in 1,6 times, IgA--in 1,3 times and IgM--in 1,7 times of the level of circulating immune complexes--in 1,6 times and decrease in fractional index and fractional number in 2 and 1,7 times accordingly. The study has shown principle efficiency of enterosorption in patients with mechanical jaundice in restoration of indices of the humoral immunity. It was seen more considerably with application of chitin-contained active substance, mycotin. It has allowed improving functional ability of the liver, especially its synthesizing function and hydroxylation processes in hepatic cells.

Abstract
BACKGROUND Ringer's ethyl pyruvate solution (REPS) has been shown to ameliorate liver injury in a murine model of extrahepatic cholestasis. The goal of the present investigation was to gain additional information about whether infusing REPS instead of Ringer's lactate solution (RLS) after inducing obstructive jaundice would be beneficial to intestinal barrier function, inflammatory response, and oxidative stress. METHODS Male Sprague Dawley rats were divided into three groups: Group Sham (n=6), sham-treated controls; Group RLS (n=9), common bile duct ligation (CBDL) plus RLS; and Group REPS (n=9), CBDL plus REPS. On 14 d after BDL, the rats were sacrificed and intestinal permeability was analyzed. Ileal IL-6 and TNF-alpha levels, malondialdehyde (MDA), glutathione (GSH), myeloperoxidase (MPO), and NF-kappaB activity were determined. Histologic examination and apoptosis of ileum were also examined. RESULTS Relative to sham-treated controls, CBDL in RLS-treated rats were associated with increased intestinal permeability to FITC-labeled dextran (4.51+/-0.85 versus 0.44+/-0.18, P<0.01), histopathologic damage and apoptosis (68.4+/-13.4 versus 6.7+/-1.9 pre-1000 villi cells, P<0.01). IL-6 and TNF-alpha level, MDA, MPO, and NF-kappaB activity in ileal tissues were also promoted, along with decreased GSH levels. Treatment with REPS significantly decreased intestinal permeability (3.37+/-0.71, P<0.01) and apoptosis (42.8+/-14.3 pre-1000 villi cells, P<0.01). Other changes were also significantly attenuated by treatment with REPS after CBDL. CONCLUSIONS The present study demonstrates that administration of REPS, but not RLS, maintains intestinal barrier function and reduces intestinal oxidative damage, inflammatory response, and apoptosis in cholestatic rats. This effect of ethyl pyruvate may be useful for preventing intestinal injury in patients with biliary obstruction.

Abstract
The aim of the article was the evaluation of the efficiency of decompression of biliary tracts and determination of optimal period of external draining. The biochemical rates of functional state of liver, dynamic of factors of humeral nonspecific defense in blood serum and bile, in 197 patients with obstructive jaundice were investigated. Concurrently, the dynamic of nonspecific defense reaction changes in infected hepatic bile, changes of amylase, pH, and bile hypertensia were studied. The obtained data are used to determine optimal period of external draining of biliary tracts. The investigation showed that early decompression of biliary tracts allows fast restore of the liver function. Restoration of natural resistance and their positive dynamic depends on the period of performance of external draining; to a lesser degree it depends on the method of performance.

Abstract
OBJECTIVE Surgery in patients with malignant obstructive jaundice is associated with increased risks for postoperative septic complications. The aim of this study was to investigate the inflammatory and the local cellular immune response in patients accepted for surgery because of tumours in the hepatic-pancreatic-biliary (HPB) tract. MATERIAL AND METHODS Patients with obstructive jaundice (group HPB(+)) were compared with those without (HPB(-)). Patients undergoing surgery for benign abdominal disorders served as controls. Obstructive jaundice was present in 18 out of 33 HPB patients. Preoperatively, blood was analysed for bacteria, endotoxins and cytokines (TNF-alpha, IL-6 and IL-10). At operation, mesenteric lymph nodes (MLNs) were excised for bacterial cultures using standard microbiological techniques, and immunohistochemistry, using antibodies CD4 and CD8 (mainly staining T lymphocytes), CD68 (macrophages), and anti-caspase-3 (to determine the rate of apoptosis). RESULTS Bacterial translocation was not demonstrated in any of the patients. Increased preoperative concentrations of endotoxins were found in group HPB(+). The number of macrophages and the rate of apoptosis in MLNs were increased in jaundiced patients, while the number of T lymphocytes was decreased. CONCLUSIONS Malignant obstructive jaundice causes increased blood concentrations of endotoxins and cytokines, an increased number of macrophages in MLNs, a higher rate of apoptosis in MLNs, but a decreased number of T lymphocytes in MLNs. The lymphocyte depletion is probably due to the increased rate of apoptosis, and might reduce the ability of jaundiced patients to eradicate infection.

Abstract
To investigate the association between chronic cholestatic jaundice, systemic immunity, and various infectious complications in patients with biliary atresia (BA), we performed a survey of the systemic immune function in 30 children with BA. Patients were divided into a jaundice group (total serum bilirubin > or = 2 mg/dL for >6 mo) and control group (total serum bilirubin <2 mg/dL for >6 mo) with comparable age. Patients were tested for serum immunoglobulin and complement levels, mitogen response, interleukin (IL)-4, IL-5, and interferon-gamma production after phytohemagglutinin (PHA) stimulation, blood cell and lymphocyte subpopulation counts, phagocytic function, and leukocyte adhesion complex. They were then followed prospectively for 6 mo, and severe infectious complications requiring hospitalization were recorded. Compared with jaundice-free patients, T-lymphocyte proliferation function, determined by PHA mitogen test was significantly lower (p = 0.02) in BA patients with chronic cholestatic jaundice after a Kasai operation. During the study period, patients with chronic cholestatic jaundice had a higher risk of severe infectious complications than their jaundice-free counterparts (risk ratio = 5.87; p = 0.001). In conclusion, BA patients with chronic cholestatic jaundice are associated with impairment of T-lymphocyte proliferation and increased incidence of severe infectious complications.

Abstract
BACKGROUND Transforming growth factor (TGF) beta is a potent inhibitor of hepatocyte DNA synthesis and liver regeneration. TGF-beta(1) expression progressively increases in obstructive jaundice. We investigated the effect of TGF-beta(1) blockage on liver regeneration in rats induced with obstructive jaundice. MATERIALS AND METHODS Male Wistar-albino rats were divided into three groups: sham, control, and study groups. In the study and control groups, the common bile duct was ligated and divided, and 7 days later a partial hepatectomy was performed. In the study group, anti-TGF-beta(1) monoclonal antibody (10-microg single dose) was administered immediately after the 70% hepatectomy. In the control group, those rats in which obstructive jaundice was induced received normal saline after the 70% hepatectomy, and nonjaundiced rats received anti-TGF-beta(1) monoclonal antibody after the 70% hepatectomy. Rats were sacrificed after 48 or 72 h. Relative liver weight, AST, ALT, total and conjugated bilirubin, and TGF-beta(1) levels were measured. The mitotic index and proliferating cell nuclear antigen (PCNA) labeling index were evaluated as histopathologic parameters. RESULTS At 72 h, the TGF-beta(1) level in the study group was similar to that in the sham group, whereas TGF-beta(1) in the study group was significantly lower than that of the jaundiced control group at 48 or 72 h (P < 0.001). The relative liver weight, mitotic index, and PCNA labeling index were significantly higher in the study group than in the jaundiced control group at 48 and 72 h (P < 0.001). The AST, ALT, and TGF-beta(1) levels were significantly higher in the jaundiced control group compared to the study group after 48 and 72 h, whereas these values were significantly lower in the nonjaundiced control group (P < 0.001). CONCLUSIONS In obstructive jaundiced rats, TGF-beta(1) blockage with anti-TGF-beta(1) monoclonal antibody after liver resection improved liver regeneration both morphologically and functionally.

Abstract
Obstructive jaundice is associated with immunologic derangements and hepatic inflammation and fibrosis. Because dendritic cells (DCs) play a major role in immune regulation, we hypothesized that the immunosuppression associated with jaundice may result from the functional impairment of liver DCs. We found that bile duct ligation (BDL) in mice expanded the myeloid subtype of liver DCs from 20 to 80% of total DCs and increased their absolute number by >15-fold. Liver myeloid DCs following BDL, but not sham laparotomy, had increased Ag uptake in vivo, high IL-6 secretion in response to LPS, and enhanced ability to activate T cells. The effects of BDL were specific to liver DCs, as spleen DCs were not affected. Expansion of liver myeloid DCs depended on Gr-1(+) cells, and we implicated monocyte chemotactic protein-1 as a potential mediator. Thus, obstructive jaundice selectively expands liver myeloid DCs that are highly functional and unlikely to be involved with impaired host immune responses.

Abstract
BACKGROUND Sclerosing pancreatitis is an autoimmune condition characterized by periductal lymphocytic infiltration on histology, and elevated serum auto-antibodies and IgG4. Bile duct involvement is often associated with sclerosing pancreatitis but it is rarely the dominant feature. CASE REPORT We report a patient with dominant biliary stricture and obstructive jaundice associated with IgG4 negative autoimmune pancreatitis. Due to uncertainties regarding the preoperative diagnosis, the patient underwent bilio-enteric bypass with an intraoperative pancreatic and bile duct biopsy. Post operatively, due to disease recurrence, the patient was started on steroids with consequent remission of the disease. CONCLUSION Sclerosing pancreatitis may sometimes present with biliary stricture due to bile duct involvement due to the inflammatory process. The condition is often recognized after surgical exploration for a suspected malignancy. Preoperative diagnosis permits treatment with steroids and endoscopic biliary decompression, and avoids unnecessary surgery.

Abstract
OBJECTIVES Autoimmune pancreatitis (AIP) is a unique clinical entity that has been recently proposed, and it is frequently associated with bile duct stricture. The aim of this study was to investigate the pathophysiology of the biliary tract involvement in patients with AIP. METHODS We evaluated the clinicopathologic findings in 16 patients with AIP. Surgical resection was performed in 7 of the patients because of suspicion of a pancreatic tumor; 8 of the other patients were treated with oral prednisolone (PSL) therapy, and the remaining patient was observed clinically and not treated. The pancreas, bile duct, and gallbladder in the surgical cases were examined histologically and immunohistochemically. We also assessed the clinical manifestations and diagnostic imaging findings before and after oral PSL therapy in the 8 patients treated with PSL. RESULTS Stricture of the extrahepatic bile duct was detected in 88% (14/16) of the patients. Thickening of the bile duct wall was detected in 94% (15/16), and thickening of the gallbladder wall was observed in 56% (9/16). Histologically, the bile duct and gallbladder wall were characterized by diffuse lymphoplasmacytic infiltration and marked interstitial fibrosis. Immunohistochemically, the diffusely infiltrating cells consisted of predominantly CD8- or CD4-positive T lymphocytes and IgG4-positive plasma cells. These findings were the same as in the inflammatory process that was observed in the pancreas. After oral PSL therapy, the pancreatic enlargement and irregular narrowing of the main pancreatic duct improved to almost their normal size in all 8 patients; however, stricture of the extrahepatic bile duct persisted in 4 of the patients (57%, 4/7) in whom it was detected before PSL therapy. CONCLUSIONS Based on the pathophysiologic and histologic findings and the response to PSL therapy, the biliary involvement in AIP developed by the same mechanism as the pancreatitis. CD8- and CD4-positive lymphocytes and IgG4-positive plasma cells may play an important role in the pathogenesis of AIP.

Abstract
BACKGROUND AND AIMS Increased numbers and enhanced functions of peripheral neutrophils have been observed in obstructive jaundice. However, the effects of obstructive jaundice on the bone marrow, that is neutrophil production and acquisition of neutrophil chemotactic activity, have been poorly understood. In the present study, differentials of bone marrow cells and chemotactic activity of bone marrow neutrophils were evaluated in bile duct-obstructed rats. METHODS Male Wistar rats underwent either bile duct obstruction for 10 days or bile duct obstruction for 4 days followed by 6 days' internal biliary drainage. Differentials of peripheral blood and bone marrow cells were sequentially determined. Chemotactic activity of peripheral and bone marrow neutrophils was evaluated with a modified Boyden method using interleukin-8 (recombinant rat Gro-beta) as a chemoattractant. RESULTS Numbers of peripheral neutrophils significantly increased after bile duct obstruction. Significant increases in the myeloid/erythroid (M/E) ratio of bone marrow cells were observed after bile duct obstruction. The neutrophil proliferative pool (promyelocytes and myelocytes) increased initially, followed by an increased neutrophil storage pool (metamyelocytes, bands, and segmented neutrophils). The M/E ratio as well as the neutrophil proliferative and storage pools normalized after internal biliary drainage. Chemotactic activity was enhanced in both peripheral and bone marrow neutrophils after bile duct obstruction, and enhanced chemotaxis was alleviated with internal biliary drainage. CONCLUSION The present results strongly suggest the principal role of the bone marrow in increasing the number of neutrophils and their chemotactic activity during obstructive jaundice.

Abstract
BACKGROUND Although the effect of preoperative biliary drainage in patients with obstructive jaundice is controversial, bacterial or endotoxin translocation is one of the main postoperative problem in jaundiced patients. Failure in gut barrier functions causes bacterial translocation; homing and distribution of T lymphocytes in the intestinal lamina propria are important for gut mucosal immune defense. This study was performed to examine whether bile regulates the numbers of T lymphocyte subsets or the expression of mucosal addressin cell adhesion molecule-1 (MAdCAM-1) in experimental jaundice in rats with and without external and internal biliary drainage. METHODS Four groups of Wistar rats were used: those that received a sham operation (SHAM), common bile duct ligation (CBDL), CBDL followed by external drainage (ED), and CBDL followed by internal drainage (ID). Numbers of CD4(+) and CD8(+) T lymphocytes and MAdCAM-1-positive cells in the lamina propria were counted immunohistochemically in the specimens of jejunum and ileum of each group. Bacterial translocation was examined by culturing from the mesenteric lymph node complex isolated from rats in each group. RESULTS A significant decrease in numbers of CD4(+) and CD8(+) T lymphocytes and MAdCAM-1-positive cells in the lamina propria was seen in obstructive jaundice, although numbers of peripheral blood lymphocytes increased in comparison with the sham-operated control. The numbers of CD4(+) and CD8(+) T lymphocytes and MAdCAM-1 expression in the lamina propria did not recover to a normal level after external drainage, but did so after internal drainage. Frequencies of bacterial translocation were high in the CBDL and ED group. In contrast, bacterial translocation was not present in any animals in the SHAM group and was at a low percentage in the ID group. CONCLUSIONS Changes in the number of T lymphocytes and MAdCAM-1 expression are associated with the presence of bile in the gastrointestinal tract and are inversely correlated with the frequency of bacterial translocation induced by CBD ligation. MAdCAM-1 expression maintained by the presence of bile may regulate T-lymphocyte homing to the lamina propria in obstructive jaundice.

Abstract
BACKGROUND/PURPOSE The effects of preoperative biliary drainage for obstructive jaundiced patients are controversial. Although experimental studies have proven the benefit of internal biliary drainage (ID) over external biliary drainage (ED), ID has several clinical problems, such as clogging or tube replacement. The aim of this study was to determine whether there were any differences in T-cell function, liver function, and histology, between rats in ID and ED groups in short-term experiments. METHODS Following bile duct ligation (BDL) for 14 days, rats in the ED and ID groups had 7 days of ED and 7 days of ID, respectively. Normal rats were used as negative controls (control group). For positive controls, we used a group with BDL and no drainage (BDL group). Serum bilirubin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) were measured, splenic T-cell proliferation was assayed to check cellular immunity, and liver histology was examined. RESULTS Recovery of bilirubin and ALT was similar in the ED and ID groups. Recovery of AST was worse in the ID group than in the ED group, but the difference was not statistically significant. Levels of ALP in the BDL and ID groups were significantly higher than those in the control and ED groups. Rats in the BDL group showed a significant decrease in T-cell function compared to the control group. The ED group showed better recovery of T-cell function than the ID group in the 7 days after relief of obstructive jaundice. The livers in the ID group demonstrated histologically moderate interface hepatitis with periportal inflammation and lymphocyte infiltration, which strongly suggested incomplete tube obstruction, but those in the ED group showed minimal change. CONCLUSIONS ED is superior to ID concerning the recovery of cellular immunity and liver inflammation in the short-term after relief from biliary obstruction in this model. As the patency of the tube is well maintained in ED compared to ID, patency of the tube is essential to obtain good recovery of cellular immunity, irrespective of the drainage method.

Abstract
The aim of this study was to investigate the relationship between the obstructive jaundice-induced cellular immune suppression and endotoxin challenge with respect to the levels of tumor necrosis factor (TNF), interleukin-10 (IL-10), and interleukin-2 (IL-2). Rats underwent either bile duct ligation or sham operation. At 21 days, all rats were challenged either with lipopolysaccharide (LPS) or saline. In the sham-operated group LPS injection significantly increased TNF levels at 90 min. The common bile duct ligated group showed a significant increase in TNF levels compared with all other groups, including the sham-operated, LPS-injected group, at 90 min. At 180 min following LPS challenge, TNF levels decreased, and there was no difference between any of the LPS-challenged groups at 180 min and any of the saline groups at either 90 or 180 min. In the sham-operated group, LPS injection significantly increased IL-10 levels at both 90 and 180 min. In the bile duct ligated group, LPS injection significantly increased IL-10 levels compared with saline injection at both 90 and 180 min. On the other hand, bile duct ligated animals had significantly less increase in IL-10 levels following LPS challenge at 90 min but not at 180 min. In common bile duct ligated rats, LPS challenge induced a significantly greater increase in IL-2 levels compared with all other groups. In conclusion, in the presence of obstructive jaundice, endotoxemia primes a more vigorous inflammatory response despite cellular immune depression.

Abstract
PURPOSE Bacterial translocation leading to sepsis is increased by obstructive jaundice(OJ). Antithrombin III (ATIII) mediates the promotion of prostaglandin release, an inhibitor of leucocyte activation and downregulator of many proinflammatory cytokines. We investigated the effect of ATIII on histopatology and villus morphology of small intestine. MATERIAL AND METHODS We designed an experimental study with 40 rats who were divided into four groups. The first one (control, n = 10) received saline, the second (n = 10) included normal rats who received ATIII, the third group (n = 10) was rats with OJ (ligation of common bile duct), and the fourth group included OJ rats receiving AT-III. AT-III (100 UI/kg intraperitoneally) was started at the third day following bile duct ligation and repeated for 5 days. At the 8 day, rats were scarified and ileum was analysed. Histopathological assessments were performed, using a grading scheme ranging from 0 to 10 (Chui et al). RESULTS Median histological score was found to be 2 in group 1, 1.71 in group 2, 5.43 in group 3 and 2.71 in group 4. The difference between group 3 and 4 was statistically significant. Mucosal thicknesses and villus lengths were found significantly lower in OJ group. Mucosal thicknesses and villus lengths were significantly preserved in jaundiced + AT-III group. CONCLUSION ATIII demonstrated a salutary effect on the histopathological changes caused by the OJ and prevented the adverse effects on histopathological and morphological parameters in ileal mucosa.

Abstract
Recently, T cells were classified into two categories: intrathymic T cells (ITCs; thymus-derived T cells) and extrathymic T cells (ETCs). ETC, localized in the liver and intestinal intraepithelium (IE), play an important immunologic role in the suppressed condition of T-cell development in the thymus. Given the fact that complications of surgery in patients with obstructive jaundice are often related to immunosuppression in the gut-liver circulation, we attempted to investigate the changes in the proportion of ETCs in mice with obstructive jaundice. Three mice models were prepared ( n = 10 per group): sham group with simple laparotomy; ligation group with common bile duct ligation; deoxycholic acid (DCA) group with an oral intake of DCA as a model of the presence of bile salts in the gut lumen. In each model, total mononuclear cells (MNCs), ITCs in the thymus, and ETCs in the liver and IE were counted using monoclonal antibodies in conjunction with a two-color immunofluorescence test by flow cytometry. In the ligation group the number of MNCs was reduced in the thymus and IE, and only those in the IE recovered after oral intake of DCA. A decrease of ITCs in the thymus and the increase in ETCs in the liver and IE occurred simultaneously during the early phase of biliary obstruction. At day 7 after biliary obstruction, ETCs in the livers of the DCA and ligation groups decreased to nearly the level in the sham group. However, on day 7 the ETCs in the IE remained significantly higher in the DCA group than in the ligation group. These results suggested that ETCs can act in place of ITCs at an early phase of obstructive jaundice, and the presence of bile in the gut lumen may be associated with the consumption of ETCs in the IE, a reaction that may bring about improved immunoreactivity.

Abstract
OBJECTS To explore the roles of the protein kinase C (PKC) signal pathway in immunologic evaluation of patients with obstructive jaundice. METHODS PKC from cytosolic and membrane fractions of peripheral blood lymphocytes (PBL) was isolated and purified, then its activities were determined by radioactive isotope gamma-32P-ATP-catalyzing assay. RESULTS Total PKC activities in PBL in patients with obstructive jaundice were significantly (r = 0.64, P < 0.01) increased as compared to those in normal subjects. Moreover, the membrane PKC activities and their percentages of the total PKC activities were higher in the patients with obstructive jaundice than in normal subjects (r = 0.63, P < 0.05). The total PKC activities in PBL were significantly correlated with the levels of soluble IL-2 receptor (sIL-2R) (r = 0.67, P < 0.01) and the degree of jaundice (T-BIL) (r = 0.58, P < 0.01) in serum. CONCLUSIONS The activities of the PKC signal pathway is related to the degree of T-BIL. PKC may be implicated in the activation of T-lymphocytes in patients with obstructive jaundice. It is suggested that the role of the PKC signal pathway may be important in the immune regulation and the assessment of pathosis in patients with obstructive jaundice.
