Antioxidant defense potential of rabbit renal tissues after ESWL: protective effects of antioxidant vitamins.

Antioxidant defense potential, malondialdehyde (MDA) levels, and relative hydroxyl radical (OH.) concentrations were measured in order to establish the effects of extracorporeal shock wave lithotripsy (ESWL) on free radical production and antioxidant defense potential of the rabbit kidney tissues. Electron microscopic examination was also performed to observe ultrastructural changes.

Impaired antioxidant defence in guinea pig heart tissues treated with halothane.

Purpose: To investigate the effects of halothane and halothane plus vitamin E treatment on myocardial free radical metabolism in guinea pigs.

Methods: Four groups of seven animals were studied: control, halothane, halothane plus vitamin E and vitamin E groups. In the halothane group, halothane 1.

Halothane hepatotoxicity and hepatic free radical metabolism in guinea pigs; the effects of vitamin E.

Purpose: The aim of this study was to investigate the relation between halothane hepatotoxicity and hepatic free radical metabolism and to establish a possible protective role of vitamin E against halothane hepatotoxicity.

Methods: Twenty-eight guinea pigs were used in the experiments. Halothane (1.
