抄録 <p>The in vivo effects of human placental extract (1-4 ml/kg) on hepatic lipid peroxidation, blood and liver glutathione (GSH) levels and several enzymes associated with the antioxidant defence mechanism; i.e., catalase, glutathione peroxidase, glutathione reductase and glutathione S-transferase, together with some blood biochemical responses were investigated in rats. At an optimal dose level (4 ml/kg), a single acute intraperitoneal administration of the extract caused a significant enhancement (49.9%; p &#60; 0.001) of lipid peroxidation with a decline in GSH level both in blood (45.1%; p &#60; 0.001) and liver (61.0%; p &#60; 0.001) in comparison to control animals. Activities of catalase, glutathione peroxidase and glutathione reductase were inhibited in a dose-responsive way by the treatment with the extract which also increased the activity of glutathione S-transferase in a dose-dependent manner. The extract was found to be hepatotoxic in terms of elevation of serum glutamate oxaloacetate transaminase, serum glutamate pyruvate transaminase, serum lactate dehydrogenase and blood methemoglobin concentration. Results of this study suggest the adverse consequences of the administration of the extract due to its substantial ability to alter normal cellular processes.</p>
