Urinary angiotensinogen level is increased in renal transplant recipients with masked hypertension and is correlated with left ventricular mass index and albuminuria in these patients.

Activation of the local renin-angiotensin system (RAS) is an independent risk factor for the development of proteinuria and left ventricular hypertrophy (LVH) more commonly seen in masked hypertensives. It has been reported that urinary angiotensinogen (UAGT) level provides a specific index of the intrarenal RAS status. The aim of this study was to evaluate the association between UAGT and left ventricular mass index (LVMI) and urinary albumin-creatinine ratio (UACR) in renal transplant recipients (RTRs) with masked hypertension (HT).

Modified back wall first artery anastomosis technique in living donor liver transplantation.

Background/objectives: Back wall technique is usually used for hepatic artery anastomosis in living donor liver-transplantation. In this technique, two stitches are placed in the two corners of the artery wall initially and the microclamp on the artery is rotated to place the sutures to the back wall first. In some cases, the microclamp cannot be rotated because of insufficient length of the graft or recipient artery.

An uncommon cause of pneumobilia: blunt abdominal trauma.

Pneumobilia is described as occurrence of free air in the gallbladder or biliary tree. There are a number of causes of pneumobilia, including surgically created biliary enteric fistula, instrumentation of the bile duct on endoscopic retrograde cholangiopancreatography, emphysematous cholecystitis, and pyogenic cholangitis. Pneumobilia has also occurred following blunt abdominal trauma, but to date, no more than five cases of such injury have been reported in the literature.

A case series of 46 appendectomies during pregnancy.

Objective: Among appendicitis patients pregnant ones occupy only a small proportion. Still there are difficulties in the diagnosis and management of the acute appendicitis in pregnant population. We tried to find answers to these difficulties with our acute appendicitis cases in pregnant patients.

Protective effects of Nigella sativa on intestinal ischemia-reperfusion injury in rats.

Background: In previous studies, it has been demonstrated that Nigella Sativa (NS) has protective effects against ischemia reperfusion injury on various organs. However, its protective effects on intestinal tissue against ischemia reperfusion injury are unclear. We aimed to determine whether NS prevents intestinal ischemia-reperfusion injury in rats.

Protective effects of Nigella sativa against ischemia-reperfusion injury of kidneys.

Background: Ischemia-reperfusion, commonly seen in the fields of trauma surgery and renal transplantation, is a major cause of acute kidney injury and is associated with significant morbidity and mortality. The protective effects of Nigella sativa against ischemia-perfusion damage to various organs have been previously documented. However, its protective effects on kidney tissue against ischemia-reperfusion injury are unclear.

[Mortality factors in flame and scalds burns: our experience in 816 patients].

Background: Our aim was to evaluate the effective factors on mortality in flame and scald burns in the Diyarbakir region.

Methods: The data of 816 patients who applied to the Dicle University Emergency Department between January 2001 and May 2005 with flame and scald burns were investigated retrospectively. The patients were separated into two groups as alive or deceased.

Purified micronized flavonoid fraction ameliorates the injury of spleen and ileum secondary to hepatic ischemia-reperfusion in rats.

Background: Flavonoids have been subjected to considerable investigations due to their antioxidant and anti-inflammatory properties. Yet the effects of flavonoids on the ileum and spleen against hepatic ischemia-reperfusion injury have so far not been addressed.

Aims: We aimed to investigate whether micronized purified flavonoid fraction (MPFF) protects the ileum and spleen against hepatic ischemia-reperfusion injury.

The efficacy of laparoscopic surgery in patients with peritonitis.

Background: Laparoscopy is an essential part of our armamentarium in certain conditions and has been recently begun to be used on acute abdominal peritonitis effectively and frequently by surgeons. But, there is still a debate on laparoscopic management of surgical emergencies. The aim of the current study is to evaluate the safety and efficiency of laparoscopy and its role in patients with acute abdominal emergencies retrospectively.

Nigella sativa relieves the deleterious effects of ischemia reperfusion injury on liver.

Aim: To determine whether Nigella sativa prevents hepatic ischemia-reperfusion injury to the liver.

Methods: Thirty rats were divided into three groups as sham (Group 1), control (Group 2), and Nigella sativa (NS) treatment group (Group 3). All rats underwent hepatic ischemia for 45 min followed by 60 min period of reperfusion.

Transabdominal approach in the surgical management of Morgagni hernia.

Purpose: Morgagni hernias are uncommon diaphragmatic hernias that are generally asymptomatic, and so far only limited data have been reported. The objective of this retrospective study was to evaluate the outcome of patients presenting with a complicated Morgagni hernia and who undergo a transabdominal repair.

Methods: Between September 1999 and October 2005, 11 patients with Morgagni hernia were operated on in our department.

Role of matrix metalloproteinase-7 in colorectal adenomas.

Matrix metalloproteinases (MMPs) degregade and remodel the extracellular matrix. They are known to be overexpressed as normal mucosa progresses to adenomas and carcinomas. In our prospective study we measured the overexpression of MMP-7 immunohistochemically in various types of colonic adenomas.

The effect of aminoguanidine against cholestatic liver injury in rats.

We investigated the protective role of aminoguanidine (AG) in rat liver injury induced by chronic biliary obstruction. Secondary biliary cirrhosis was induced by bile duct ligation for 14 days. Swiss albino rats were divided into three groups: Common bile duct ligated (CBDL) rats; Group A, CBDL rats treated with AG as Group B and simple laparotomy group known as the Sham group; Group C.

Protective effect of resveratrol against oxidative stress in cholestasis.

Background: We investigated the protective role of resveratrol in rat liver injuries induced by chronic biliary obstruction.

Materials And Methods: Secondary biliary cirrhosis was induced by bile duct ligation for 28 days. Swiss albino rats were divided into the three following groups: group 1: sham (n = 7); group 2: bile duct ligation (n = 7); group 3: bile duct ligation plus resveratrol (n = 7).

Protective effect of resveratrol against renal oxidative stress in cholestasis.

Background/aims: This experimental study was designed to evaluate histological changes of the kidney and renal tissue levels of malondialdehyde (MDA), reduced glutathione (GSH), and nitric oxide (NO) and the effect of resveratrol on these metabolites after bile duct ligation in rats.

Methods: Secondary biliary cirrhosis was induced by bile duct ligation for 28 days. Swiss albino rats were divided into three groups.

Protective effect of melatonin against oxidative stress on adhesion formation in the rat cecum and uterine horn model.

This experimental study was designed to evaluate the degree of adhesion formation and peritoneal tissue levels of malondialdehyde (MDA), reduced glutathione (GSH) and nitric oxide (NO) and the effect of melatonin on these metabolites in a postoperative intraperitoneal adhesion formation model in rats. Thirty adult female Wistar albino rats were subjected to standardized lesions by cecal and uterine horn abrasion and were randomly divided into three groups. Control rats were treated with 5% ethanol.
