Changes in nitric oxide (NO) levels were determined in ischaemic acute renal failure in streptozotocin-induced diabetes mellitus rats. Two weeks after streptozotocin administration and immediately after right nephrectomy, the left renal artery was occluded for 60 min. Similar procedures were carried out in non-diabetic rats. The nitrite (NO2) + nitrate(More)
In the present prospective study we examined the long-term effect of intravenous supplementation with ferric saccharate (IV Fe) in the treatment of the anemia of chronic dialysis patients. All patients, 64 on chronic hemodialysis (HD) and 9 on chronic ambulatory peritoneal dialysis (CAPD), were treated intravenously with this preparation in a dose of 100 mg(More)
A prospective study among unselected patients hospitalized in an internal medicine ward showed that 46 patients, 6.9% of total admissions, had serum concentrations of sodium less than 132 mEq/l. In 28.3% of hyponatremic patients (n = 13), the cause was the syndrome of inappropriate antidiuretic hormone secretion; 21.7% of the cases (n = 10) developed(More)
AIM To evaluate the efficacy and mechanism of action of NCB 02, a standardized Curcumin preparation, against 2, 4 dinitrochlorobenzene (DNCB) induced ulcerative colitis in rats. METHODS Ulcerative colitis was induced in male rats by sensitizing with topical application of DNCB in acetone for 14 d and intra-colonol challenge with DNCB on day 15. A separate(More)
BACKGROUND Rats with chronic renal failure have a low nitric oxide (NO) production and a diminished NO excretion. The supplementation of L-arginine has an inhibitory effect on the progression of renal insufficiency. METHODS The present study was designed to determine whether chronic renal failure patients have a low NO production. Plasma and urine nitrate(More)
BACKGROUND Most dialysis patients develop pruritus, for which current treatment is unsatisfactory. Endogenous opioids may be involved in this pruritus. We studied the effect of the opioid antagonist naltrexone on the pruritus of haemodialysis patients. METHODS Naltrexone 50 mg per day by mouth was given to 15 haemodialysis patients with severe resistant(More)
Iron deficiency may develop in hemodialysis patients, especially when erythropoietin is given. The role of iron deficiency in the anemia of predialysis chronic renal failure (CRF), however, is much less clear. We have intravenously (IV) administered iron as ferric saccharate in a total dose of 200 mg elemental iron monthly for 5 months to 33 CRF patients(More)
EDRF results from the metabolism of L-arginine. N-omega-nitro-L-arginine is a nitric oxide synthase inhibitor (L-arginine competitive inhibitor). Acute renal failure was induced by i.m glycerol (50%) 5 ml/kg bw. L-arginine: 3 mg/kg bw/min for 60 min before and 60 min after glycerol administration. L-arginine inhibitor (150 micrograms/kg bw/min for 120 min).(More)
Sclerosing peritonitis (SP) has come to be recognized as a serious complication of peritoneal dialysis (PD). However, diagnosis is often established at a late stage of the disease and at laparotomy. The use of computerized tomography (CT) of the abdomen in 2 patients, clinically suspected of suffering from SP, revealed loculated ascites, adherent bowel(More)
This study was undertaken to examine the possible role of endothelium-derived relaxing factor (EDRF), identified as nitric oxide (NO), in the pathogenesis of radiocontrast-induced acute renal failure in rats. Normal and salt-depleted rats were monitored for 60 min or 24 h after radiocontrast administration. The administration of L-arginine to normal rats(More)
