| Research Abstract |
Halothane, isoflurane and sevoflurane attenuated ischemia-reperfusion injury in the perfused liver of fasted rats, suggesting a possible involvement of ischemic preconditioning.
In the rat liver slice incubation, isoflurane attenuated apoptosis induced by hypoxic challenge. Suppression of apoptosis is predominant in the hepatocyte.
Direct effect of isoflurane on K-ATP channel was studied in isolated pancreatic β cells using whole cell patch clamp method. Isoflurane suppressed K-ATP channel in a dose-dependent manner. Repeated treatment of isoflurane enhanced the suppression of K-ATP channel.
