AI Article Synopsis
- This study aimed to investigate how zinc might protect against liver damage caused by halothane, an anesthetic, in male Sprague-Dawley rats.
- Three groups of rats were tested: one with halothane only, one with halothane plus zinc, and a control group receiving normal diet and water.
- Results showed that the rats receiving zinc had lower liver damage markers and reduced liver toxicity compared to those that only received halothane.
Article Abstract
Background And Objective: This study was designed to determine the protective effects of zinc on halothane induced hepatotoxicity.
Methods: Forty-five male Sprague-Dawley rats were divided into three groups. The halothane group received normal drinking water and diet; the zinc-halothane group received 227 mg L(-1) zinc sulphate in the drinking water and diet for 2 weeks; and the control group received normal diet and water. At the end of 2 weeks, rats were housed in an anaesthesia box and 1 MAC (minimum alveolar concentration)halothane was administered at 6 L min(-1) in room air for 2 h. This was repeated 48 h later. After the rats were sacrificed, we measured alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, gammaglutamyl transpeptidase, glutathione-S-transferase, serum electrolytes and bilirubin in samples. The degree of liver toxicity was assessed by light microscopic examination.
Results: We demonstrated a reduction of alanine aminotransferase, aspartate amino transferase, glutathione-S-transferase levels and a reduction in liver damage in the zinc-halothane group.
Conclusion: The study concludes that zinc has the potential to alleviate the toxic effects of halothane in rat liver.
