BACKGROUND Carnitine loss through dialysis membranes is shown to be related to the lack of carnitine in long-term haemodialysis patients. It has been previously reported that haemodialysis patients might have benefited from carnitine supplementation. METHODS A total of 21 chronic haemodialysis patients maintaining carnitine supplementation and 21 controls(More)
SUMMARY : Reactive oxygen metabolites (ROMs) contribute to tissue injury in inflammatory bowel disease. The aim of this study is to examine the role of ROMs in the tissue injury in ulcerative colitis (UC). The study group consisted of 27 patients with UC (14 active, 13 quiescent) and a control group of 10 patients with various anal diseases. We measured the(More)
In the present study, we assessed oxidative stress in patients with dilated cardiomyopathy of ischemic or idiopathic etiology. For this reason we measured whole blood reduced glutathione, erythrocyte superoxide dismutase, susceptibility of erythrocyte membranes and erythrocytes to peroxidation, and SH content of erythrocyte membranes in 12 patients (8 men(More)
It is a well-known fact that laparoscopic procedures performed with carbon dioxide insufflation impair myocardial function. In this study, we aimed to determine the safety limitations of various intra-abdominal pressure values during abdominal insufflation with carbon dioxide. Of the 24 mongrel dogs, 6 were assigned to one of four different pressure groups(More)
The molecular mechanisms of migraine have not been fully clarified yet. Increased nitrosative and oxidative stress may be associated with migraine attacks. Platelets may play an important role in migraine patients and they can reflect the lability of tissues to nitrosative/oxidative stress. In the present study, we aimed to determine the levels of(More)
Clinical chemists frequently encounter hemolyzed samples. Our study examines the effects of hemolysis on the results of 25 common biochemical tests. We collected 60 15-mL blood samples from inpatients and outpatients and mechanically hemolyzed 10 mL of the samples in a two-step procedure. We classified serum from these samples as being nonhemolyzed,(More)
BACKGROUND Cardiovascular diseases are important factors in mortality and morbidity of dialysis patients. Cardiovascular risk assessment is important in order to arrange the treatment strategies. The aim of the study was to investigate the relationship between carotid atherosclerosis and various CVD risk factors in dialysis patients. METHODS 22 HD and 54(More)
BACKGROUND Peritonitis is an important complication in continuous ambulatory peritoneal dialysis (CAPD) patients. Procalcitonin (PCT) has recently been identified as an inflammation marker and recommended as a new potential marker in CAPD peritonitis. We aimed to study a card test for PCT and compare the results with the conventional markers such as(More)
BACKGROUND Increased nitric oxide (NO) production may result in further brain damage via nitric oxide synthase uncoupling in patients with acute ischaemic stroke by increasing free radical formation and oxidative stress. In this connection, we measured nitrite and nitrate (NO metabolites), ischaemia-modified albumin (IMA) and thiobarbituric acid-reactive(More)
