Abstract
Primary or metastatic hepatic malignancies are common. Partial hepatectomy (PH) is the primary treatment for both benign and malignant hepatic neoplasms; it also is used for living donor liver transplantation. The regenerative potential of the liver after PH is 70-80% in humans. We investigated the protective and therapeutic effects of agomelatine (AGM) on rat liver regeneration following PH. We used 32 rats distributed equally into four groups: group 1, sham control; group 2, PH group; group 3, administered 20 mg/kg AGM orally once/day for 7 days following PH; group 4, administered 20 mg/kg AGM orally once/day 3 days before and 7 days following PH for 10 days. Liver samples were analyzed for antioxidants and free radicals. Tissue samples were processed and stained with hematoxylin and eosin to assess histopathological status and stained immunohistochemically for Ki-67. We found that PH reduced antioxidant enzymes and increased tissue reactive oxygen species, whereas AGM treatment had the opposite effect on these parameters. Our biochemical and histopathological findings were consistent. PH caused sinusoid congestion and dilation. Intensity of Ki-67 immunostaining of hepatocytes was increased in group 2, whereas these were reduced in group 4. Intensity of Ki-67 immunostaining of hepatocytes was increased in group 2, whereas it was reduced in the group 4 compared to group 1. We found that AGM was hepatoprotective following PH due to its antioxidant and free radical scavenger properties.

Abstract
OBJECTIVE We aimed to present our experience with the management of 17 patients with ascites who underwent diagnostic laparoscopy or laparotomy, and histologic confirmation of wet ascitic type of peritoneal tuberculosis (TB). PATIENTS AND METHODS Between January 2008 and March 2019, 17 patients whose ascites were investigated by a gastroenterologist and who were thought to have non-cirrhotic ascites were referred to our Surgery clinic for peritoneal biopsy. The clinical, biochemical, radiological, microbiological, and histopathological data of the patients who underwent diagnostic laparoscopy or laparotomy were analyzed retrospectively. Histopathological examination of peritoneal tissue samples in hematoxylin-eosin-stained preparations revealed necrotizing granulomatous inflammation with caseous necrosis and Langhans type giant cells. Ehrlich-Ziehl-Neelsen (EZN) staining was studied with the suspicion of TB. Acid-fast bacilli (AFB) were detected in EZN stained slide. Histopathological findings were also considered. RESULTS Seventeen patients aged 18 to 64 years were included in this study. The most common symptoms were ascites and abdominal distention, weight loss, night sweats, fever and diarrhea. Radiological examination revealed peritoneal thickening, ascites, omental cacking, and diffuse lymphadenopathy. Histopathologically, necrotizing granulomatous peritonitis consistent with peritoneal TB were detected. While direct laparoscopy was preferred in sixteen patients, laparotomy was preferred in the remaining one due to previous surgical procedures. However, seven were converted to open laparotomy. CONCLUSIONS Diagnosis of abdominal TB requires high index of suspicion, and the treatment should be prompt to reduce the morbidity and mortality associated with delay in treatment.

Abstract
BACKGROUND AND AIM Biliary complications are an important cause of mortality and morbidity after living donor liver transplantation (LDLT). We present our endoscopic treatment results after LDLT as a single center with high volume. METHODS Patients who underwent endoscopic retrograde cholangiopancreatography (ERCP) after LDLT between 2005 and 2015 were included. Clinical data included patient demographics, ERCP indications (stricture or leak), and treatment outcomes, including need for percutaneous and surgical interventions. RESULTS ERCP was performed in 446 (39.2%) patients with duct-to-duct anastomosis of 1136 LDLT patients. The most common biliary complication was stricture ± stone (70.6%, 315/446). Stricture and leak occurred in 60 (13.4%) patients. Only biliary leak was found in 40 (8.9%) patients. Our endoscopic treatment success rate in patients with biliary stricture after LDLT was 65.1%. Overall endoscopic success rates in our patients were 55.0% in patients with both leak and stricture, and only leak. In all, our percutaneous transhepatic biliary interventions (PTBI) and ERCP success rate was 90.6% in patients with biliary complications after LDLT. CONCLUSIONS Endoscopic treatments are highly effective for biliary complications after LDLT. Effective use of percutaneous interventions in collaboration with endoscopic treatments significantly reduces the need for surgical treatment.

Abstract
OBJECTIVE Increased nitric oxide (NO) production in cirrhotic patients causes splanchnic vasodilation, leading to the development of the hyperdynamic circulatory syndrome. One factor that influences plasma NO concentration is eNOS gene polymorphism; consequently, the aim of this study was to investigate whether the eNOS gene G894T and T-786C polymorphisms play any role in the development of ascites in such patients. PATIENTS AND METHODS Three groups were created: 70 cirrhotic patients with ascites, 69 cirrhotic participants without ascites (stable cirrhosis), and 60 healthy controls. Polymorphisms were determined using polymerase chain reaction (PCR) and melting curve analysis. The plasma nitrite (NO marker) level was measured by deploying the spectrophotometric Griess reaction. RESULTS Plasma nitrite levels in the cirrhosis with ascites and stable cirrhosis groups were significantly higher than in the controls (p < 0.0001). The frequency of GG, GT, and TT genotypes for the eNOS G894T polymorphism in the cirrhosis with ascites group was 55.7%, 38.6%, and 5.7% respectively, while in the stable cirrhosis group these figures were 60.9%, 36.2%, and 2.9%. In the controls, the distribution was 63.3%, 33.3%, and 3.3%, respectively. The frequency of TT, TC, and CC genotypes for the eNOS-786C polymorphism in the first group was 52.9%, 34.2%, and 12.9% respectively; in the second group, this was 46.4%, 42%, and 11.6%, and in the controls, 48.3%, 46.7%, and 5%. There were no significant differences in genotype and allele distributions of the eNOS-786C and eNOS G894T polymorphisms among the groups. CONCLUSIONS Plasma nitrite concentration is enhanced in cirrhotic patients, and there is no relationship between the G894T and eNOS-786C polymorphisms and the development of ascites.

Abstract
Free iron leads to the formation of pro-oxidant reactive oxygen species (ROS). Humic acids (HAs) enhance permeability of cellular wall and act as a chelator through electron transferring. This study was designed to test chelator effect of HA on iron as well as its anti-oxidant effect against the iron-induced hepatotoxicity and cardiotoxicity. The rats used were randomly divided into four groups (n = 8/group): group I (the control group); group II (the HA group), humic acid (562 mg/kg) was given over 10 days by oral gavage; group III (the iron group), iron III hydroxide polymaltose (250 mg/kg) was given over 10 days by intraperitoneal route; and group IV (the HA plus iron group), received the iron (similar to group II) plus humic acid (similar to those in groups II and III) group. Blood and two tissue samples both from liver and heart were obtained for biochemical and histopathological evaluations. Iron deposition, the iron-induced hepatotoxicity, and cardiotoxicity were demonstrated by histopathological and biochemical manner. However, no significant differences were observed in the serum biochemical values and the histopathological results among the iron and the HA plus iron groups in the liver tissue but not in the heart tissue. The protective effects of humic acid against iron-induced cardiotoxicity were shown but not against hepatotoxicity in our study.

Abstract
Background and study aim: The aim of the present study was to investigate the effects of Lycium barbarum (LB) on bacterial translocation (BT) frequency in thioacetamide (TAA)-induced liver injury in rats. Materials and methods: Group 1 was the control. In group 2 (TAA), rats received TAA daily for 3 days. In group 3 (TAA+LB), Lycium barbarum was administered orally 25 mg/kg for 21 days prior to the first TAA injection. In group 4 (LB), rats received only Lycium barbarum. Results: In our study, Lycium barbarum treatment did not attenuate liver damage. Lycium barbarum treatment decreased ileal E. coli counts and intestinal damage but it did not alter BT frequency. Conclusions: In conclusion, the effects of Lycium barbarum on BT may be related to ongoing severe liver damage in this model.

Abstract
BACKGROUND AND AIMS Percutaneous endoscopic gastrostomy (PEG) is insertion of a tube to stomach through abdominal wall for provision of nutrition in patients who couldn't be fed by oral route. In the present study, it was aimed to evaluate PEG procedures performed in our facility regarding indication, complication and effectiveness and to determine whether these characteristics have a relationship with advancing age. MATERIAL AND METHODS In this descriptive study, we reviewed clinical and endoscopic records of 300 patients who underwent PEG procedure between May 2009 and December 2011. The patients were divided into 2 groups(group 1 > 75, group 2 < 75 years). All patients were retrospectively reviewed regarding demographic data, indications, biochemical parameters (Hemoglobin, total protein and albumin) at baseline and 3 months after procedure, complications and mortality. RESULTS The most common indication for PEG was neurological (67.3%). Wound infection (6.0%) was most common early complication while tube occlusion (4.7%) was most common late complication. No significant difference was detected between groups regarding morbidity and mortality (p < 0.05). It was seen that there were significant improvement in all biochemical parameters (p < 0.001). The most significant improvement was observed in total protein values (p < 0.05). However, no significant difference was detected in individual parameters (p > 0.05). CONCLUSIONS PEG should be preferred at early period in patients who couldn't be fed by oral route for prolonged time as it is a minimally invasive, simple, inexpensive, highly effective, physiologic and safe. PEG was found to have no relationship with advancing age regarding indications, morbidity, mortality rate and effectiveness.

Abstract
BACKGROUND AND STUDY AIMS Oxidative stress plays an important role in development of intestinal injury after abdomino-pelvic radiation therapy. Teucrium polium (TP) is a medicinal plant which has antioxidant and anti-inflammatory properties. The aim of this study was to investigate the effect of TP on radiation-induced intestinal oxidative damage in rats. MATERIALS AND METHODS Group 1 (n = 8), the control group; Group 2 (n = 8), the RAD (radiation) group in which each rat received a single whole-body 800 cGy radiation performed with a LINAC ; Group 3 (n = 8), the RAD + TP group in which rats were exposed to radiation as in Group 2, followed by intragastric administration of 0.5 g/kg/daily TP extract for 7 consecutive days; and Group 4 (n = 8), the TP group, rats received only intragastric TP for 7 days. RESULTS Radiation led to intestinal damage, which was accompanied by an increase in intestinal thiobarbituric-acid-reactive substances (TBARS) and myeloperoxidase (MPO) levels, and a decrease in reduced glutathione (GSH) levels. Although TP significantly decreased intestinal MPO levels and inflammation scores, it neither reverted intestinal TBARS and GSH levels nor ameliorated other histological parameters of the disease. CONCLUSIONS Our results suggest that TP reduces inflammation but does not ameliorate the increased oxidative stress conditions in radiation-induced intestinal damage in rats.
