Effects of toxaphene on hepatic enzyme induction and circulating steroid levels in the rat.
نویسنده
چکیده
Rats were given a single dose of toxaphene (120 mg/kg, equivalent to 1/2 LD50) and sacrificed at 1, 5, and 15 days. Liver weight and hepatic microsomal enzyme activity were increased at day 5 and 15. The level of plasma testosterone was significantly decreased at day 15. In a second experiment rats were given 2.4 mg/kg daily and sacrificed at 1, 3 and 6 months. Liver weight and microsomal enzyme activity were significantly increased over controls; enzyme activity was, however, decreasing by the end of the experiment. Plasma testosterone levels were not affected. It is concluded that enhanced hepatic enzyme induction causes only a transient drop in circulating testosterone levels followed by a return to normal values.

Incubation of rat hepatocytes with epinephrine inhibited alanine aminotransferase (ALT) (80%) and aspartate aminotransferase (AST) (53%) activities with no effect on lactate dehydrogenase (LDH) activity. Injection of epinephrine caused a progressive increase with time in hepatic LDH activity, being 52% at 24 h. Preinjection with propranolol eliminated the hormone effect and caused further ...

The objective of this study was to contribute to investigate the efficacy of letrozole, a potent non-steroidal aromatase inhibitor, on serum sex steroid levels and oocyte growth in rainbow trout females. Serum steroid levels were measured using an indirect enzyme-linked immunosorbent assay (ELISA) before and 22 days after an initial injection with 1, 2.5 mg kg-1 and subsequent weekly injection ...
متن کاملTrans-chalcone enhances insulin sensitivity through the miR-34a/SIRT1 pathway
Objective(s): Trans-chalcone as the parent member of the chalcone series reduces circulating levels of insulin and glucose. However, the cellular mechanism of these effects is poorly understood. Sirtuin 1 (SIRT1) as a direct target of miR-34a controls homeostasis of glucose, and also improves insulin sensitivity. Therefore, the present study for the first time investigated the influence of tran...
