Abstract
PURPOSE Rapamycin reduces hepatic fibrosis by inhibiting hepatic stellate cell activation. The present study investigated whether rapamycin treatment could modify the degree of fibrosis, cellular apoptosis and oxidative stress (OS) in an experimental model of CP. METHODS Fifty-five male, Sprague-Dawley rats weighing 200-400g were randomized into four groups. CP was induced by intraductal trinitrobenzene sulfonic acid (TNBS) infusion in group A (n = 15) and group B (n = 15). Group C (n = 15) received intraductal TNBS and was killed for histologic confirmation at four weeks. Group D (n = 10) received intraductal saline instead of TNBS. Group A and group D received oral rapamycin (2 mg/kg/d) for two weeks after CP was induced while group B received oral tap water instead of rapamycin. Blood and pancreatic tissue specimens were collected and oxidative stress parameters, fibrosis and cellular apoptosis were determined. RESULTS Tissue and blood malondialdehyde (MDA) levels were significantly lower in rapamycin treated group compared to controls (p < 0.001). Superoxide dismutase (SOD) and glutathion peroxidase (GSH-Px) activities were also significantly higher in the active treatment group (p < 0.001 for both). Tissue and blood MDA, SOD, GSH-Px measurements was similar in rapamycin group and pancreatic cannulation group (p > 0.05). Histopathologic fibrosis scores were similar in rapamycin and control groups. Apoptotic cell counts tended to be lower in rapamycin treated animals. CONCLUSIONS Administration of rapamycin alleviated OS and, in part, prevented apoptotic cell death in experimental CP, but did not reduce fibrosis.

Abstract
Burkitt lymphoma predominantly involving the pancreas is very rare. There is no specific clinical, laboratory, or radiological sign of the disease. Thus, the diagnosis, especially of focal involvement, is usually difficult. We here report ultrasonography, computed tomography and magnetic resonance imaging findings of primary pancreatic Burkitt lymphoma in a case with unusual radiological presentation.

Abstract
AIM: To search the organelle based changes in hepatocytes after taurine treatment in experimental liver fibrosis induced by CCl4 administration.
METHODS: Thirty rats were divided into two groups. Group 1 (n = 15) was injected with CCl4 plus taurine and Group 2 (n = 15) with CCl4 plus saline for 12 wk. At the end of 12th wk, mitochondria, rough and smooth endoplasmic reticulum, and nuclei of hepatocytes were evaluated using a scoring system. The results were compared with histopathological findings, as well.
RESULTS: Taurine treatment reduced fibrosis scores significantly as compared to placebo. Organelle injury scores decreased significantly with taurine treatment. Ultrastructural and histopathological scores in both groups were in strong correlation (r = 0.931 for CCl4 plus taurine and r = 0.899 for CCl4 plus saline group).
CONCLUSION: Organelle based transmission electron microscopy findings can reflect successfully histological results as well as tissue healing in hepatocytes from hepatotoxin-induced liver fibrosis.

Abstract
AIM To investigate the individual and combined effects of allopurinol and hyperbaric oxygen (HBO) therapy on biochemical and histopathological changes, oxidative stress, and bacterial translocation (BT) in the experimental rat acute pancreatitis (AP). METHODS Eighty-five Sprague-Dawley rats were included in the study. Fifteen of the eighty-five rats were used as controls (sham, Group I). AP was induced via intraductal taurocholate infusion in the remaining seventy rats. Rats that survived to induction of acute necrotizing pancreatitis were randomized into four groups. Group II received saline, Group III allopurinol, Group IV allopurinol plus HBO and Group V HBO alone. Serum amylase levels, oxidative stress parameters, BT and histopathologic scores were determined. RESULTS Serum amylase levels were lower in Groups III, IV and V compared to Group II (974 +/- 110, 384 +/- 40, 851 +/- 56, and 1664 +/- 234 U/L, respectively, P < 0.05, for all). Combining the two treatment options revealed significantly lower median [25-75 percentiles] histopathological scores when compared to individual administrations (13 [12.5-15] in allopurinol group, 9.5 [7-11.75] in HBO group, and 6 [4.5-7.5] in combined group, P < 0.01). Oxidative stress markers were significantly better in all treatment groups compared to the controls. Bacterial translocation into the pancreas and mesenteric lymph nodes was lower in Groups III, IV and V compared to Group II (54%, 23%, 50% vs 100% for translocation to pancreas, and 62%, 46%, 58% vs 100% for translocation to mesenteric lymph nodes, respectively, P < 0.05 for all). CONCLUSION The present study confirms the benefit of HBO and allopurinol treatment when administered separately in experimental rat AP. Combination of these treatment options appears to prevent progression of pancreatic injury parameters more effectively.

Abstract
AIM: To examine the ultrastructural changes after ursodeoxycholic acid (UDCA) treatment in hepatocytes from experimentally induced fibrotic livers.
METHODS: Liver fibrosis was induced in male Sprague-Dawley rats with CCl4 for 12 wk, and the rats were divided into two groups. Group I was treated with saline and group II with UDCA (25 mg/kg per day) for 4 wk. All the rats were killed at wk 16. Mitochondria, nuclei, rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER) of hepatocytes were evaluated according to a scoring system.
RESULTS: Mitochondria, nuclei, RER and SER injury scores in group II were significantly lower than those in groupI(P < 0.001).
CONCLUSION: UDCA alleviates hepatocyte organelle injury in CCl4-induced liver fibrosis.

Abstract
BACKGROUND Vascular risk factors are blamed as being involved in the pathogenesis of cognitive dysfunction in the elderly. Alzheimer's disease or vascular-type dementia could be part of a metabolic syndrome. The aim of this study was to evaluate whether there is any relation between insulin resistance and cognitive status of the elderly regarding normal, mild cognitive impairment (MCI), Alzheimer's disease (AD), vascular dementia (VaD) and mixed dementia. METHODS 267 elderly patients admitted to an outpatient geriatrics clinic were evaluated medically and cognitively in this study. The patients were diagnosed using ARDRA and DSM-IV criteria for AD; NINDS-AIREN and DSM-IV criteria for VaD; and Petersen criteria for MCI. Insulin resistance was calculated using both the homeostasis model assessment (HOMA) and quantitative insulin sensitivity check index (QUICKI) formulas. RESULTS The mean values of HOMA and QUICKI scores were 2.79 (SD+/-3.56) and 0.346 (SD+/-0.036) for the normal group, 2.81 (SD+/-3.06) and 0.354 (SD+/-0.047) for AD group, 2.20 (SD+/-1.82) and 0.360 (SD+/-0.048) for VaD group, 2.87 (SD+/-1.81) and 0.339 (SD+/-0.038) for mixed dementia group, 2.79 (SD+/-2.81) and 0,349 (SD+/-0.042) for MCI group, respectively. There were no statistically significant differences between HOMA and QUICKI scores of all the groups. CONCLUSION This is the first study of the possible relation between insulin resistance and cognitive function in people categorized according to five forms of cognitive status. Unfortunately the results do not allow generalizations. Further prospective cohort studies that follow a normal cognitive group and MCI patients with and without insulin resistance are necessary.

Abstract
AIM: To investigate the antifibrotic effects of peginterferon-alpha 2b and taurine on oxidative stress markers and hepatocellular apoptosis.
METHODS: Sixty rats with CCl4-induced liver fibrosis were divided into 4 groups (n = 15). Group 1 was left for spontaneous recovery (SR). Groups 2-4 received peginterferon-alpha 2b, taurine, and their combination, respectively, for four weeks. Histological fibrosis scores, histomorphometric analysis, tissue hydroxyproline, tissue MDA, GPx and SOD activities were determined. Activated stellate cells and hepatocellular apoptosis were also evaluated.
RESULTS: The degree of fibrosis decreased in all treatment groups compared to spontaneous recovery group. Taurine alone and in combination with peginterferon-alpha 2b reduced oxidative stress markers, but peginterferon-alpha 2b alone did not. Apoptotic hepatocytes and activated stellate cells were higher in groups 2-4 than in group 1. Combined taurine and peginterferon-alpha 2b further reduced fibrosis and increased activated stellate cell apoptosis, but could not improve oxidative stress more than taurine alone.
CONCLUSION: Peginterferon-alpha 2b exerts anti-fibrotic effects on rat liver fibrosis. It seems ineffective against oxidative stress in vivo. Peginterferon-alpha 2b in combination with taurine seems to be an antifibrotic strategy.

Abstract
OBJECTIVES Based on the results of recent studies that reported depleted antioxidant capacity in patients with chronic pancreatitis (CP), prevention of free radical production has gained importance in antifibrotic treatment strategies in CP. The aim of this study was to investigate the effects of taurine on oxidative capacity and fibrosis in experimental chronic rat pancreatic fibrosis. METHODS CP was induced in male Sprague-Dawley rats by intraductal trinitrobenzene sulfonic acid (TNBS) dissolved in ethanol. Taurine was given intraperitoneally at a concentration of 1000 mg/kg. The treatment groups were as follows: group 1, TNBS plus normal saline (NS); group 2, TNBS plus taurine; group 3, ethanol plus NS; and group 4, NS plus NS. Each group contained 15 animals. Treatment was started after established CP. After 4 weeks of treatment, markers of oxidative stress and the degree of pancreatic fibrosis were determined. RESULTS The amount of weight loss was significantly lower in the taurine-treated group with CP (P < 0.002). Tissue malondialdehyde levels increased and superoxide dismutase and glutathione peroxidase activities decreased significantly after treatment as well (P < 0.001). Histopathologic scores were also lower in taurine-treated animals with CP (P < 0.005). CONCLUSIONS Taurine treatment improved the degree of oxidative stress and fibrosis in rat CP. Antioxidant treatment might be considered a novel option to alleviate the fibrotic process in CP.

Abstract
INTRODUCTION Acute pancreatitis is a local inflammatory process that leads to a systemic inflammatory response in the majority of cases. Bacterial contamination has been estimated to occur in 30-40% of patients with necrotizing pancreatitis. Development of pancreatic necrosis depends mainly on the degree of inflammation and on the microvascular circulation of the pancreatic tissue. Activated protein C (APC) is known to inhibit coagulation and inflammation, and to promote fibrinolysis in patients with severe sepsis. We investigated the effects of APC on histopathology, bacterial translocation, and systemic inflammation in experimental acute necrotizing pancreatitis. MATERIALS AND METHOD Forty-five male Sprague-Dawley rats were studied. Rats were randomly allocated to three groups. Acute pancreatitis was induced in group II (positive control; n = 15) and group III (treatment; n = 15) rats by retrograde injection of taurocholate into the common biliopancreatic duct. Group I rats (sham; n = 15) received an injection of normal saline into the common biliopancreatic duct to mimic a pressure effect. Group III rats were treated with intravenous APC 6 hours after induction of pancreatitis. Pancreatic tissue and blood samples were obtained from all animals for histopathological examination and assessment of amylase, tumor necrosis factor-alpha, and IL-6 levels in serum. Bacterial translocation to pancreas and mesenteric lymph nodes was measured. RESULTS Acute pancreatitis developed in all groups apart from group I (sham), as indicated by microscopic parenchymal necrosis, fat necrosis and abundant turbid peritoneal fluid. Histopathological pancreatitis scores in the APC-treated group were lower than in positive controls (10.31 +/- 0.47 versus 14.00 +/- 0.52; P < 0.001). Bacterial translocation to mesenteric lymph nodes and to pancreas in the APC-treated group was significantly decreased compared with controls (P < 0.02 and P < 0.007, respectively). Serum amylase, tumor necrosis factor-alpha, and IL-6 levels were also significantly decreased in comparison with positive controls (P < 0.001, P < 0.04 and P < 0.001, respectively). CONCLUSION APC improved the severity of pancreatic tissue histology, superinfection rates and serum markers of inflammation during the course of acute necrotizing pancreatitis.

Abstract
Oxidative stress is important in pathogenesis of liver fibrosis, which is the result of deposition of excessive ECM proteins produced by activated hepatic stellate cells (HSCs). Reducing reactive oxygen species (ROS) production decreases collagen accumulation in liver. We investigated the benefits of antioxidant therapy in liver fibrosis and its association with HSC apoptosis. Forty-five male Spraque-Dawley rats were subdivided into three groups. Group I was treated with CCl(4) plus taurine, Group II with CCl(4) plus saline, and Group III with saline for 12 weeks. Erythrocyte and liver malondialdehyde (MDA) levels, superoxide dismutase (SOD) activities, Glutathione peroxidase (GSHpx) activities, and serum and liver TIMP-1 and MMP-13 levels were measured. Histopathological examinations were performed. Activated and total HSCs were quantified immunohistochemically. Apoptotic HSCs were detected by terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) staining. Taurine decreased histopathological injury scores and oxidative stress parameters significantly. The number of activated HSCs was significantly higher in taurine untreated group ( [Formula: see text] ). Serum and tissue MMP-13 levels were significantly higher and TIMP-1 levels were significantly lower in taurine-treated group ( [Formula: see text] and [Formula: see text], respectively). The number of apoptotic activated hepatic stellate cells was significantly higher with taurine treatment ( [Formula: see text] ). Preventing the production of reactive oxygen species is effective in inhibiting fibrogenesis in experimental rat model. Inhibitory activity of this agent on HSCs' activation, apoptosis, and further fibrogenic events should be clearly identified.

Abstract
The aim of this study is to assess the relationship between the carotid wall intima media thickness (IMT) and atheroma plaques due to atherosclerosis and platelet aggregation among elderly. The first stage of the study was performed by analyzing platelet aggregation in a total of 28 elderly patients divided into two groups. The first group consisted of 14 cases with carotid atheroma plaque (Patient group I) and the second group of patients were without carotid atheroma plaque (Control group I). At the second stage of the study, the cases were regrouped according to the carotid IMT. Patients with IMT above 1 mm (Patient group II, n=10) and under 1 mm (Control group II, n=14) were compared regarding platelet aggregation. Platelet aggregation was induced in the platelet-rich plasma using 5 micro M ADP, 0.2 mg/ml collagen and 1.2 mg/ml ristocetin. Between patients with and without atheroma, no difference was noted in terms of platelet aggregation. Between platelet aggregation results of patients with intimal thickness above and under 1 mm, no significant difference was also noted. Between elderly cases with or without atherosclerosis, there was no difference with respect to platelet aggregation. Platelet aggregation measurements cannot be used as a marker of atherosclerosis in elderly population.

Abstract
INTRODUCTION Recent data from the experimental clinical studies suggest that antibiotics having good penetration to pancreas may reduce mortality by preventing pancreatic infection, which is the most important prognostic factor in acute pancreatitis (AP). Deferoxamine is an active free oxygen radical scavenger, which has been shown to have a protective role in development of acute pancreatitis. AIM To determine the effects of combination of deferoxamine and meropenem in acute necrotizing pancreatitis. METHODOLOGY One hundred male Sprague-Dawley rats were randomly divided into 5 groups. All rats underwent laparotomy with cannulation of biliopancreatic duct. Group 1 received intraductal saline injection. Acute necrotizing pancreatitis was induced in group 2, 3, 4, and 5 by intraductal injection of 3% taurocholate. Group 1 (sham operated) and group 2 were injected with saline of 0.3 mL/kg intraperitoneally (i.p). Group 3 was injected with meropenem 60 mg/kg/d i.p, group 4 with deferoxamine 80 mg/kg/d s.c and group 5 with combination of these 2 agents at the same doses. While meropenem was started 2 hours later, all treatments were started immediately after the induction of pancreatitis. All rats were killed at the 48th hour of the treatment and blood and tissue samples were collected for amylase determinations, pathologic examinations, and culture. RESULTS There was no difference in serum amylase levels between AP induced groups (P > 0.05). Pancreatic histology scores were significantly low in rats treated with deferoxamine (group 4), and combination regimen (group 5) (P < 0.001). Meropenem significantly reduced the incidence of pancreatic infection. Although combination of deferoxamine with meropenem showed better effects than meropenem alone in terms of pancreatic infection, the difference did not reach to statistical significance. CONCLUSIONS Meropenem treatment reduces secondary pancreatic infections in acute pancreatitis. Treatment with deferoxamine and meropenem combination may be more beneficial than single therapies in reducing the severity of pancreatitis. Further studies investigating the effects of this combination on survival are needed.

Abstract
BACKGROUND Secondary infection of the inflamed pancreas is the principal cause of death after severe acute pancreatitis (AP). Although patients are not always managed early in the course of AP in clinical practice, prophylactic antibiotics that were used in experimental studies in rats were always initiated early after induction of pancreatitis. The effectiveness of antibiotics initiated later is unknown. AIM The aim of this study was to compare the effectiveness of ciprofloxacin and meropenem initiated early versus later in the course of acute necrotizing pancreatitis (ANP) in rats. METHODS 100 Sprague-Dawley rats were studied. ANP was induced in rats by intraductal injection of 3% taurocholate. Rats were divided randomly into five groups: group I rats received normal saline as a placebo, group II and IV rats received three times daily meropenem 60 mg/kg i.p. at 2 and 24 h, respectively and group III and V rats received twice daily ciprofloxacin 50 mg/kg i.p. at 2 and 24 h, respectively, after induction. At 96 h, all rats were killed for quantitative bacteriologic study. A point-scoring system of histological features was used to evaluate the severity of pancreatitis. RESULTS Meropenem and ciprofloxacin initiated 2 h after induction of pancreatitis significantly reduced the prevalence of pancreatic infection (p < 0.001 and p < 0.04, respectively) as compared to controls. Neither of the antibiotics initiated later during the course of AP caused a significant decrease in pancreatic infection in rats (p > 0.05). Although the rats treated early infected less frequently than the rats treated later, the comparison reached statistical significance only in the meropenem group (p < 0.02). CONCLUSION Early antibiotic treatment reduces pancreatic infection more efficiently than late antibiotic treatment in ANP in rats.

Abstract
INTRODUCTION Translocation of bacteria from the gut is one of the most important factors in the development of septic complications and mortality in acute pancreatitis. AIMS To investigate whether S-methylisothiourea (SMT), taurine (TAU), and meropenem (MER) could effect bacterial translocation and the course of acute necrotizing pancreatitis. METHODOLOGY Seventy male Sprague-Dawley rats were studied. Rats were randomly allocated into seven groups. Acute pancreatitis was induced in group II (MER), group III (TAU), group IV (TAU + MER), group V (TAU + SMT), group VI (TAU + MER + SMT), and group VII (positive control) by retrograde injection of taurocholate into the common biliopancreatic duct. Group I rats (sham) received normal saline infusion into the common biliopancreatic duct as negative control. Rats were treated with drug combinations intraperitoneally for 48 hours after induction of pancreatitis. At the 48th hour of induction, all animals were killed, and specimens were collected. RESULTS Bacterial translocation to peritoneum and pancreas in groups treated with MER were lower than in the other groups. Pancreatic tissue GSHpx and SOD levels were higher in all groups in comparison with levels in group VII. Pancreatic tissue MDA levels were also lower in all treatment groups except group II. The most favorable results were obtained in group VI (TAU + MER + SMT). Also, the lowest pathologic score between the groups in which acute pancreatitis developed was obtained in group VI. CONCLUSIONS Addition of TAU and SMT to the treatment protocol for acute pancreatitis seems to improve the pathologic score and oxidative stress parameters. Also, antibiotherapy with MER decreases the risk of bacterial translocation.

Abstract
PCR is a rapid, sensitive and accurate method for the specific detection of Helicobacter pylori from gastric biopsy specimens. In our study, 104 gastric tissue specimens from symptomatic adult patients were examined by staining, culture, PCR and nested PCR methods for detection of H. pylori. According to our results, positivity was achieved in 24% (25/104) with Giemsa staining, 34% (36/104) with histopathology, 36% (38/104) with PCR and 41% (43/104) with nested PCR respectively, whereas H. pylori was isolated in only 33% (35/104) of the cultures on the biopsy specimens. Both the sensitivity and the positive predictive value of the nested PCR method were 100%, and both the specificity and negative predictive value were 98%. As a conclusion, our results suggest the nested PCR as a highly valuable method in the detection of H. pylori with a reasonably high sensitivity and specificity.

Abstract
INTRODUCTION Recent data from experimental and clinical studies suggest that the antibiotics showing good penetration into the pancreas may reduce mortality by preventing pancreatic infection, which is the most important prognostic factor in acute pancreatitis. AIM To determine and compare pancreatic tissue concentrations of meropenem and cefepime at different stages of acute necrotizing pancreatitis in an animal model that has been shown to closely mimic severe human pancreatitis. METHODOLOGY Acute necrotizing pancreatitis was induced in rats by a standardized intraductal infusion of glycodeoxycholic acid and intravenous cerulein. Six hours (n = 30) and 48 hours (n = 30) after induction of pancreatitis, the rats were randomized to receive an intravenous 20 mg/kg injection of either meropenem or cefepime. Blood and the head of the pancreas were collected for determining antibiotic concentrations by high-performance liquid chromatography. RESULTS Meropenem concentrations in the pancreas at 6 hours of acute pancreatitis increased significantly and decreased at 48 hours of the disease, but were still higher than that in controls. Concentrations of cefepime in necrotic pancreatic tissue were significantly low either during the initial or later phase, but lower in latter, in which the necrosis was more evident. Tissue/serum concentration ratios of meropenem were significantly higher than those of cefepime. However, tissue concentrations of both antibiotics are much higher than the minimum inhibitory concentration values for the common microorganisms involved in pancreatic infections. CONCLUSION Although both antibiotics penetrate into the necrotic tissue in sufficient therapeutic concentrations, penetration of meropenem is much better than cefepime. However, good tissue penetration may not solely indicate efficacy of that antibiotic. Therefore, further experimental and clinical studies are needed to determine the therapeutic and prognostic efficacy of these agents.

Abstract
BACKGROUND There has been considerable interest in gall bladder motility in recent years. We compared the effects of cholecystokinin (CCK) and erythromycin on bile chemistry and gallstone formation in aged guinea pigs. METHODS Two groups of guinea pigs (1-mo and 3-y old; n=40 each) were studied. Each group was divided into four subgroups of 10 animals each; one subgroup received lithogenic diet, one each received CCK or erythromycin daily in addition to lithogenic diet for 4 weeks, and one received normal diet. After 4 weeks, the presence of gallstones or sludge was recorded and bile composition including concentrations of bile acid, cholesterol, lecithin and protein concentrations was studied. RESULTS No gallstones were observed in the 1-mo-old animals. In the 3-year-old animals, 9 of 10 guinea pigs on lithogenic diet and 4 of 10 in each treatment subgroup and the normal diet subgroup developed gallstones. CCK and erythromycin had similar effects on bile chemistry and stone formation. CONCLUSIONS Aging increases the formation of gallstones in guinea pigs. Erythromycin is as effective as CCK in reducing gallstone formation by improving gall bladder motility.

Abstract
INTRODUCTION Translocation of bacteria from the gut into pancreatic necrosis is an important factor in the development of septic complications and mortality in acute pancreatitis. S-methylisothiourea (SMT) is an inducible nitric oxide synthase inhibitor that has been shown to decrease bacteria] translocation in sepsis and thermal injury. AIM To investigate whether SMT could affect bacterial translocation in acute necrotizing pancreatitis. METHODOLOGY Forty-five Sprague-Dawley rats were studied. Acute pancreatitis was induced in Group I and Group II by injection of taurocholate and trypsin into the common biliopancreatic duct. Group III underwent laparotomy with the manipulation (but not cannulation) of the pancreas and received saline injection. Group I rats received normal saline as a placebo, and Group II rats received SMT after surgery for 2 days. At 48 hours, blood was drawn for serum amylase determinations. Bacterial translocation to mesenteric lymph nodes and distant sites (pancreas, liver, and peritoneum) were examined. A point scoring system of histologic features was used to evaluate the severity of pancreatitis. RESULTS Plasma amylase levels and pancreatic histologic score were significantly reduced in Group II rats given SMT compared with those in Group I rats given saline (p < 0.01, p < 0.05, respectively). All Group I rats had bacterial translocation to mesenteric lymph nodes compared with 7 of 12 rats in Group II (p < 0.05). There was no difference in bacterial translocation to distant organs between the two groups, although rates tended to be lower in Group II compared with Group I (p > 0.05). Bacterial counts in the pancreas were significantly reduced in Group II rats compared with those in Group I rats (p < 0.05). CONCLUSION Treatment with SMT appears to have ameliorated the course of acute pancreatitis; however, mortality was not affected.

Abstract
The suprarenal glands are normally located at the superomedial aspect of the kidneys. Accessory cortical masses are seen in approximately half of the newborn but usually disappear later. Several cases with accessory cortical tissues located near the main suprarenal glands have been reported but their usual locations have been rarely described. Here we report a case with accessory cortical tissue located on the right in the retrocrural space with compression symptoms. Such a lesion may be confused with lymphadenopathy radiologically.

Abstract
BACKGROUND Non-alcoholic steatohepatitis is a chronic liver disease that is capable of progressing to end-stage liver disease, but generally has a benign course. Obesity, non-insulin-dependent diabetes mellitus and hyperlipidaemia are the most common associations of the disease. AIMS To investigate the insulin resistance in patients with non-alcoholic steatohepatitis who have no other causes of insulin resistance such as obesity, diabetes mellitus, and hyperlipidaemia. PATIENTS Thirteen patients (7 male, 6 female) with non-alcoholic steatohepatitis and 12 (6 male, 6 female) healthy volunteers. METHODS All patients and healthy volunteers were submitted to biochemical tests and hyperinsulinaemic euglycaemic insulin clamp technique. RESULTS Basal insulin levels and C-peptide levels were significantly higher in non-alcoholic steatohepatitis group than in controls (p<0.001 and p<0.001, respectively). Hyperinsulinaemic euglycaemic insulin clamp technique revealed lower glucose utilization in the non-alcoholic steatohepatitis group and the difference was statistically significant (p<0.001). CONCLUSIONS Our study revealed marked hyperinsulinaemia and insulin resistance in patients with non-alcoholic steatohepatitis. Hyperinsulinaemia and insulin resistance may contribute to pathogenesis of nonalcoholic steatohepatitis.

Abstract
OBJECTIVE It has been suggested that the oral cavity and dental plaque might be a reservoir for Helicobacter pylori (Hp). In this study, our aims were to detect the prevalence of Hp colonization in dental plaque and tongue scrapings of patients with chronic gastritis and to investigate the effect of systemic treatment upon this colonization and eradication of Hp from gastric mucosa. METHOD AND MATERIALS Eighty-one patients (49 men, 32 women) were included in the study. Dental plaque and tongue scraping specimens were obtained and assessed with Campylobacter-like organism (CLO) test, prior to endoscopic examination. By endoscopy, 2 antral and 1 corpus biopsy samples were taken for histologic examination, and 1 antral biopsy sample was taken for CLO test examination. RESULTS Chronic gastritis was diagnosed in 63 (77.7%) of 81 patients. Dental plaque samples of 64 (79%) patients and tongue scraping samples of 48 (59.2%) patients were urease positive. Of the 63 patients with chronic gastritis, dental plaque and tongue scrapings were urease positive in 52 (83%) and 37 (59%) patients, respectively. After 14 days of triple drug therapy (omeprazole, clarithromycin, and amoxicillin), Hp was eradicated from the gastric mucosa of almost all of the patients, whereas no changes were detected in dental plaque and tongue scrapings by CLO test examination. CONCLUSION Helicobacter pylori colonization, which seemed to be high in dental plaque and on the tongue, might play an important role in the pathogenesis of the reinfection process. In order to eradicate Hp from both the oral cavity and the gastric mucosa, studies should be performed to assess the effects of plaque control procedures in addition to present treatment modalities.

Abstract
BACKGROUND Most malignancies with peritoneal infiltration, especially ovarian cancers and chronic liver diseases associated with ascites give rise to high serum CA-125 levels. Tuberculous peritonitis is another cause for high serum CA-125 levels. AIM To investigate the relation between serum CA-125 level and response to treatment in tuberculous peritonitis patients. PATIENTS Ten patients with tuberculous peritonitis were enrolled in the study. METHOD Definite diagnosis of tuberculous peritonitis was made by acid-fast smears, specific culture, and polymerase chain reaction. Serum CA-125 levels were measured before and at the fourth month of treatment. RESULTS Before antituberculous treatment, serum CA-125 levels of all patients were very high (mean+/-SD: 475. 80+/-106. 19 U/ml) and comparable with those of patients with ovarian cancers. At the end of the fourth month of treatment, serum CA-125 levels in all patients decreased to within normal limits (<35 U/ml)(20.80:+/-5.18 U/ml) in parallel with the clinical improvement. The differences in CA125 levels before and after treatment were statistically significant (p<0.001). CONCLUSIONS Results of our study suggest that serum CA-125 levels in patients with tuberculous peritonitis are as high as ovarian cancers associated with peritoneal infiltration. By the end of the fourth month of antituberculous therapy, serum CA-125 levels have returned to normal. We, therefore, suggest that serum CA-125 can be used to evaluate the efficacy of therapy in tuberculous peritonitis.

Abstract
A 20-year-old male, with no history of chronic liver disease, presented with fulminant hepatic failure. The cause was not established until post mortem when it was found that he had a primary hepatocellular carcinoma in a non-cirrhotic liver. To our knowledge, this is the third report of hepatocellular carcinoma presenting in this manner. Although rare, primary malignancies of the liver should be considered in the differential diagnosis of fulminant hepatic failure, especially when other more common causes are excluded.
