Oxidant/antioxidant balance has been suggested as an important factor for initiation and progression of cancer. In order to determine whether the degree of oxidative DNA damage and antioxidant enzyme activities in plasma obtained from patients with gastric and colon cancer who undergo resection can be used as a useful prognostic predictor, plasma level of(More)
The purpose of this study was to examine the effects of sildenafil citrate on normal and ischemic colon anastomosis in the rat model by measuring the levels of blood and colonic tissues nitric oxide, thiobarbituric acid reactive substrates (as a marker of lipid peroxidation), and glutathione (as an antioxidant). Normal (group 1 and 3) and ischemic(More)
Glutamine (Gln), which is the most abundant free amino acid in the circulation, and also a primary fuel for rapidly dividing cells, was used to determine its effects on incisional healing. The effect of Gln-enriched feeding was investigated using tensile strength measurement, which reflects the quality and speed of regeneration, and by the measurement of(More)
Diethylstilbestrol (DES) analyses were carried out on muscle, liver, kidney and faeces samples of 20 control and 20 experimental broilers to which 5 mg DES/day had been given orally for a period of 7 days. The treated samples were analysed using the Radioimmunoassay method. The removal time of DES from the tissues was determined. Five days following the(More)
