Abstract:
This study was designed to investigate the relationship between the hepatotoxicity of Halothane and altered hepatic calcium homeostasis in enzyme-induced hypoxic rats by means of Ca2+ cytochemistry location and EDX microanalysis combined with micropathological stereology of liver and ultrastructural analysis by computer. The results showed that more calcium precipitated the cytoplasm and mitochondria of liver following Halothane exposure than the controls. Based on the experiments, this alteration appeared to be contributed to the accelerated uptake of Ca2+ by the hepatocytes and lessened to pump out the decreased loaded Ca2+ on the other hand. The release of the reserved Ca2+ was increased by Halothane as compared with controls. These results suggest that a loss of regulation of cellular Ca2+ levels plays an important role in the mechanism of hepatotoxicity by Halothane exposure.
