Effect of volatile anesthetics on protein synthesis and secretion by rat hepatocyte suspensions.
The effect of volatile anesthetics on protein synthesis and secretion by isolated rat hepatocytes in suspension was investigated. Halothane and enflurane inhibited protein synthesis in a dose-dependent manner. Diethyl ether had little effect on protein synthesis while isoflurane caused a mild inhibition. This effect was more pronounced in hepatocytes from phenobarbital treated male rats when compared to hepatocytes from control rats. Protein synthesis in hepatocytes from phenobarbital treated female rats was inhibited similar to that seen with control male rat hepatocytes. Isoflurane, enflurane, and halothane also caused a dose-dependent inhibition of protein secretion, while diethyl ether was only mildly inhibitory. From these studies it appears that inhibition of protein synthesis and secretion might be an early and sensitive indicator of cellular injury by volatile anesthetics.
