Abstract/OtherAbstract:
1. The effect of glutathione (GSH) depletion on rabbit renal medullary homogenate 6-ketoPGF1 alpha and TxB2 synthesizing capability was investigated. 2. GSH depletion in vivo with diethyl maleate (DEM) produced higher (P less than 0.05) 6-ketoPGF1 alpha and TxB2 renal medullary levels compared to controls. Homogenization and incubation lowered (P less than 0.05) GSH such that there were no differences in GSH between treatments after 5 min of incubation. By 30 min, GSH was lower (P less than 0.05) and 6-ketoPGF1 alpha higher (P less than 0.05) in homogenates from controls in comparison to those from DEM-treated rabbits. 3. The results indicate GSH depletion increased 6-ketoPGF1 alpha levels in rabbit renal medulla in vivo but subsequent GSH catabolism prevented assessing the effect of this GSH depletion on prostanoid synthesizing capability.
