This study aimed to investigate the effect of dietary sunflower meal (SFM) and multi-enzyme levels on performance, carcass traits, intestinal histomorphology and pancreatic enzyme production in quails. Three hundred and twenty, 1-day-old quail chicks were divided into 8 groups with 4 replicates consisting of 10 birds each in the group. The experiment was randomized design consisting of a 4 × 2 factorial arrangement, with four levels of SFM (0%, 10%, 15%, or 20%) and two levels of multi-enzyme (0.

A total of 800 day-old broiler chicks were assigned to four test diets to assess the efficacy of phytase, fermented from , and boron, as boric acid, on the growth performance and mineral profile in chickens. The dietary treatments included the basal diet and the basal diet supplemented with boron (20 mg/kg), phytase (500 phytase units/kg diet), or a combination of boron and phytase. The following parameters were measured: growth performance indices, serum biochemicals, ash and the mineral profile of the tibia, breast muscle, liver and excreta.

Background: Acute pancreatitis is the major complication of endoscopic retrograde cholangiopancreatography (ERCP) procedure and there are some reports showing cytokine changes in ERCP-induced pancreatits.

Goals: To investigate the association between early changes (within 24 hours) in the serum interleukin (IL)-2, IL-4, tumor necrosis factor (TNF)alpha, and IL-6 levels and the development of post-ERCP pancreatitis.

Study: Forty five consecutive patients who underwent therapeutic ERCP and 10 patients with acute pancreatitis without ERCP were enrolled to the study.

Background And Study Aims: Caustic ingestion caused by swallowing a detergent can produce a progressive and devastating injury in the esophagus and stomach. One of the most important outcomes of the corrosive oesophagitis is the stricture formation, which is resistant to treatment. The aim of this study was firstly to determine the relation between agent, inflammation and stricture, and secondly investigate the efficiency of dilation in patients having esophageal stricture due to corrosive oesophagitis.

McArdle's disease, or myophosphorylase deficiency, is one of the most common muscle glycogenoses and typically presents in childhood or adolescence with exercise intolerance, myalgia, myoglobinuria, and cramps in the exercising muscle. We report the case of a 21-year-old male patient with liver enzyme elevation who had a history of weakness, exercise intolerance, and muscle cramps since childhood. His sister (a three-year- old) suffered from similar symptoms.

Background: Since it was described in 1980, percutaneous endoscopic gastrostomy (PEG) has been a widely used method for insertion of a gastrostomy tube in patients who are unable to swallow or maintain adequate nutrition. The aim of the present paper was to determine the complications of PEG insertion and to study pre- and post-procedural nutritional status.

Methods: During the period of March 1999-September 2004, placement of PEG tube was performed in 85 patients (22 women and 63 men).

Familial Mediterranean fever (FMF) is a recessively inherited inflammatory disorder, characterized by recurrent attacks of fever and polyserositis. It has been considered that miscellaneous cytokines take part in the pathogenesis of the disease. The aim of this study was to investigate serum levels of soluble interleukin-2 receptor (sIL-2R), interleukin-6 (IL-6), and interleukin-10 (IL-10) in patients with FMF.

Background And Aims: Leptin, a recently discovered protein, acts as a hormonal feedback signal in regulating adipose tissue mass via hypothalamic mechanisms. Inflammatory bowel disease is often associated with anorexia and weight loss. The aim of the present study was to investigate serum leptin levels during the time course of the acute phase of ulcerative colitis (UC) and to evaluate whether leptin leads to anorexia and bodyweight loss in these patients.

Some difficulties have been encountered in treating pregnant patients with choledocholithiasis because of the probable harmful effect of scopic irradiation on fetus when endoscopic retrograde cholangiopancreatography (ERCP) is necessary. In this paper, we present such a patient, in whom endoscopic stone extraction without scopic examination was successfully carried out in the guidance of magnetic resonance cholangiopancreatography (MRCP) before the ERCP procedure.

Objectives: In this study we aimed to determine the levels of Glutathione peroxidase (GSH-Px) and Malondialdehyde (MDA) in patients with inflammatory bowel disease (IBD) to investigate their contribution to tissue injury in inflammatory bowel disease.

Design And Methods: Forty-seven GSH-Px patients (35 with ulcerative colitis and 12 with Crohn's disease) and 30 healthy controls were included in the study. Their plasma and MDA levels were compared using nonparametric statistical methods.
