treatments of melatonin on the cisplatin-induced lipid peroxidation, LDH release and plasma creatinine were determined in rabbit renal cortical cells. The level of malondialdehyde (MDA) was assayed as an index of lipid peroxidation and the level of LDH release as an indicator of cellular damage. In in vitro studies, cisplatin increased the levels of MDA and LDH release in a concentration-and time-dependent manner. Melatonin inhibited the cisplatin-induced lipid peroxidation and LDH release in a...

In the rabbit renal artery, acetylcholine (ACh, 1 nM∼10μM) induced endothelium-dependent relaxation of arterial rings precontracted with norepinephrine (NE, 1μM) in a dose-dependent manner. NG-nitro- L-arginine (L-NAME, 0.1 mM), an inhibitor of NO synthase, or ODQ (1μM), a soluble guanylate cyclase inhibitor, partially inhibited the ACh-induced endothelium-dependent relaxation. The ACh-induced relaxation was abolished in the presence of 25 mM KCl and L-NAME. The cytochrome P450 inhibitors,...

for 24-h did not alter 1-h water intake in 24-h water-deprived rats, but prevented the increase in overnight water intake after 24-h water-deprivation. Six-day i.c.v. treatment of AS-ODN did not alter either the basal plasma renin concentration or renal cortical levels of renin and renin mRNA. The present results suggest that endogenous brain Ang II plays an important role in thirst and water intake through AT1 receptors, but further studies are required to elucidate its regulatory role in renal...

of renal cortical endocytotic vesicles (endosomes). The endosomal acidification was assessed by measuring the pH gradient-dependent fluorescence change, using acridine orange or FITC-dextran as a probe. In renal endosomes isolated from Cd-intoxicated rats, the Vmax of ATP-driven fluorescence quenching (H⁢-ATPase dependent intravesicular acidification) was significantly attenuated with no substantial changes in the apparent Km, indicating that the capacity of acidification was reduced. When...

renal tubular brush-border membranes (BBM) to free cadmium (Cd) causes a reduction in phosphate (Pi) transport capacity. Biochemical mechanism of this reduction was investigated in the present study. Renal proximal tubular brush-border membrane vesicles (BBMV) were isolated from rabbit kidney outer cortex by Mg precipitation method. Vesicles were exposed to 50∼200 μM CdCl2 for 30 min, then the phosphate transporter activity was determined. The range of Cd concentration employed in this study...

muscle (VSM) cells is altered in renal hypertension. Two-kidney, one clip (2K1C) and deoxycorticosterone acetate (DOCA)-salt hypertension were made in Sprague-Dawley rats. Rats without clipping the renal artery or implanting DOCA were used as control for 2K1C and DOCA-salt hypertension, respectively. Four weeks after clipping, systolic blood pressure was significantly higher in 2K1C rats than in control (192⁑24 and 119⁑4 mmHg, respectively, n=16 each). DOCA-salt rats also showed a...

This study was undertaken to examine the effect of ethanol on Na⁢-dependent transport systems (glucose, phosphate, and dicarboxylate) in renal brush-border membrane vesicles (BBMV). Ethanol inhibited Na⁢- dependent uptakes of glucose, phosphate, and succinate in a dose-dependent manner, but not the uptakes of Na⁢-independent. The H⁢/TEA antiport was reduced by 8% ethanol. Kinetic analysis showed that ethanol caused a decrease in Vmax of three transport systems, leaving Km...

The present study was designed to assess the roles of PLA2 activation and arachidonic acid (AA) metabolites in hypoxia-induced renal cell injury. Hypoxia increased LDH release in a dose-dependent manner in rabbit renal cortical slices, and this increase was significant after 20-min hypoxia. The hypoxia-induced LDH release was prevented by amino acids, glycine and alanine, and extracellular acidosis (pH 6.0). Buffering intracellular Ca2⁢ by a chelator, but not omission of Ca2⁢ in the...

ANG II (10⁣9 M)-induced inhibition of Na⁢ uptake was blocked by losartan (10⁣8 M, AT1 antagonist), but not by PD123319 (10⁣8 M, AT2 antagonist) (P＜0.05). ANG II-induced inhibition of Na⁢ uptake was also completely abolished by neomycin (10⁣4 M, PLC inhibitor), W-7 (10⁣4 M, calmodulin antagonist), and AACOCF3 (10⁣6 M, PLA2 inhibitor) (P＜0.05)....

The present study was undertaken to examine the role of phospholipase A2 (PLA2) in oxidant-induced inhibition of phosphate transport in primary cultured rabbit renal proximal tubule cells. Uptakes of phosphate and glucose were dose-dependently inhibited by an oxidant t-butylhydroperoxide (tBHP), and the significant inhibition appeared at 0.025 mM of tBHP, whereas tBHP-induced alterations in lipid peroxidation and cell viability were seen at 0.5 mM. tBHP stimulated arachidonic acid (AA) release...
