In patients with end-stage renal disease (ESRD), the 25-hydroxyvitamin D3 (25(OH)D3) level is known to be lower compared to that of the normal population. In the present study, we evaluated the influences of dialysis methods on the serum 25(OH)D3 level in patients with ESRD who are treated with hemodialysis and peritoneal dialysis. Thirty-nine peritoneal(More)
AIMS The aim of this experimental study was to evaluate the effects of Ginkgo biloba (EGb 761) on ischemia-reperfusion (I-R) injury in the rat bladder. METHODS A bladder I-R injury was induced by abdominal aorta occlusion by ischemia for 30 min, followed by 45 min reperfusion in rats. The rats were divided into four groups of 7 rats each; the control,(More)
Septic shock has a high mortality rate due to the hypotension and circulatory disorder that occurs during its pathogenesis. Recently, humoral factors such as cytokines and nitric oxide became important in the complex pathophysiology of septic shock because there is a close relationship between the determined levels of these humoral factors and the responses(More)
The fruit of Physalis peruviana L. (PPL) has been traditionally used as antispasmodic, diuretic, antiseptic, sedative, and analgesic all over the world. We aimed to perform qualitative content analysis of the fruits of PPL and to clarify the in vitro genotoxicity and in vivo acute and subchronic toxicity of the fruit. Lyophilized fruit juice does not induce(More)
The purpose of this study was to measure the effects of electromagnetic waves (EMW) at 900 MHz. EMW were produced by a signal generator and were administered to mice via an antenna. The frequency of the waves was tested by a spectrum analyser and a frequency-meter. The emitted power was 0.25 mW. A total of 117 mice (59 prepubertal and 58 adult) was used.(More)
It is known that digoxin, which is a liposoluble cardiac glycoside, is well absorbed from intestine. In the present study, the absorption rates of digoxin from rat duodenum and the proximal and terminal parts of small intestine were determined in vitro. The isolated everted duodenum and intestinal sacs were put into oxygenated Tyrode solution at 37 degrees(More)
The present study aimed to compare the effect of gender difference on hemodynamic consequences in the development of monocrotaline (MCT)-induced pulmonary hypertension in rat. The effect of antioxidant enzyme systems on the development of pulmonary hypertension mediated by the phytotoxin MCT and the effect of gender on these antioxidant systems were also(More)
In this study, 6-[(4-arylidene-2-phenyl-5-oxoimidazolin-1-yl)phenyl]-4,5-dihydro-3(2H)-pyridazinone and 4-[(4-arylidene-2-phenyl-5-oxoimidazolin-1-yl)phenyl]-1(2H)-phthalazinone derivatives were synthesized by reacting 6-(4-aminophenyl)-4,5-dihydro-3(2H)-pyridazinone or 4-(4-aminophenyl)-1(2H)-phthalazinone compound with different(More)
BACKGROUND & OBJECTIVES Several studies have shown the possible analgesic effects of gabapentin, widely used as an antiepileptic. Thus, clinical studies have been carried out especially for neuropathic syndroms. This study was undertaken to investigate experimentally whether gabapentin has analgesic effects in mice and rats. METHODS The mice were divided(More)
BACKGROUND/AIM Posttransplant steroid doses have been reduced with the use of new and potent immunosuppressive agents. However, posttransplant osteoporosis is still a serious problem. Our aim in this study was to investigate the effect of low-dose cholecalciferol and calcium supplementation on bone loss after transplantation in renal transplant patients. (More)
