The temporal variation in the nephrotoxicity of low doses of isepamicin was studied in male Sprague-Dawley rats treated with a single daily intraperitoneal injection of saline (NaCl, 0.9%) or isepamicin (80 mg/kg of body weight) at either 0800, 1400, 2000, or 0200 h for 4 and 10 days. On day 10, the cellular regeneration (incorporation of [3H] thymidine(More)
The present study was designed to determine the temporal changes in tobramycin nephrotoxicity during the dark and the light periods of the day and to look for the mechanisms of such changes. Female Sprague-Dawley rats (9 to 11 weeks old) were housed in a 14-h-light-10-h-dark cycle (lights on 0600 to 2000 h). A bolus of tobramycin (60 mg/kg of body weight)(More)
The effects of short-term food deprivation on the serum and renal distribution and nephrotoxicity of tobramycin were studied in female Sprague-Dawley rats maintained on a 14-h light/10-h dark cycle (light on: 06:00). For the distribution study, a single injection of tobramycin (40 mg/kg, i.p.) was administered at 14:00 or 02:00 to normally fed animals or to(More)
The circadian and the circannual variations of the nephrotoxicity of tobramycin were studied in female Sprague-Dawley rats. Animals were maintained on a light-dark period of 14/10 hrs (light on: 06h00 to 20h00). They were injected once daily for 4 and 10 days with saline or tobramycin at a dose of 40 mg/kg/day i.p. at either 08h00, 14h00, 20h00 and 02h00,(More)
The lipopeptidic antibiotic daptomycin is reported to reduce experimental tobramycin nephrotoxicity (D. Beauchamp, M. Pellerin, P. Gourde, M. Pettigrew and M. G. Bergeron, Antimicrob. Agents Chemother. 34:139-147, 1990; C. A. Wood, H. C. Finkbeiner, S. J. Kohlhepp, P. W. Kohnen, and D. C. Gilbert, Antimicrob. Agents Chemother. 33:1280-1285, 1989). In an(More)
OBJECTIVE To study the expressions of Th1 and Th2 type cytokines in patients with esophageal squamous cell carcinoma and the influence of operation on such expressions. METHOD Enzyme-linked immunosorbent assay (ELISA) was used to detect Th1 (IL-2 and INF-gamma) and Th2 type cytokines (IL-4, IL-6 and IL-10) in cultured peripheral blood mononuclear cells(More)
Novel N(4)-hydroxy- and 5-methyl-modified beta-L-deoxycytidine analogues were synthesized and evaluated as anti-hepatitis B virus (HBV) agents. Their in vitro efficiencies were investigated in HepG2.2.15 cells stably transfected with HBV. beta-L-2',3'-Didehydro-2',3'-dideoxy-N(4)-hydroxycytidine (beta-L-Hyd4C) was most effective in reducing secreted HBV DNA(More)
