We selected 9 PD patients, 10 HD patients, and 9 control subjects for the study. In those patients, we determined levels of serum lipids, hs-CRP, Hcy, vitamin B12, folic acid, and leptin. Patients on PD had a significantly elevated hs-CRP concentration (3.14 +/- 0.79 mg/L) and ratio of total cholesterol (TC) to high density lipoprotein (HDL) cholesterol (4.71 +/- 0.40), and their cardiovascular risk was found to be three times that of control subjects. In HD patients, the elevation of hs-CRP was more profound (5.66 +/- 1.30), but their TC:HDL ratio fell within the normal range (3.18 +/- 0.13). However, a cardiovascular risk assessment of...

Gentamicin (GM), a commonly used antibiotic exhibits a toxic effect on renal proximal tubules. Prevention of its nephrotoxicity is important. Therefore, we investigated whether heme oxygenase (HO)-1 induction influenced kidney and vascular function in GM-administered rats. GM (100 mg/kg/day; ip) was given to rats alone or together with hemin (20 mg/kg/alternate days; ip.) for 14 days. Plasma and kidney L-arginine, asymmetric dimethylarginine (ADMA) and symmetric dimethylarginine (SDMA) as well as kidney 4-hydroxynonenal (HNE) levels and myeloperoxidase (MPO) activity were measured. Histopathologic examinations of kidney and relaxation and contraction responses of aorta were also examined. GM increased serum SDMA, urea nitrogen (BUN), and creatinine levels and caused histopathologic alterations in kidney. GM elevated HO-1 protein...
