ABSTRACT
To investigate the effect and mechanism of NK-1 Tachykinin receptor (NK-IR) antagonist on hypoxia induced hepatic injury, we established the hypoxic rat model. 30 male SD rats (weighing 240-300g) were randomly divided into 3 groups, control group, and experimental groups including the hypoxia group and the NK-1R antagonist group. The rats of experimental groups underwent hypoxia, among them the NK-1R antagonist group were those with interference of NK-1R antagonist by intraperitoneal injection. Hepatic injury was evaluated by pathological staining, hepatic function detection and hepatocellular apoptosis determination. Results showed hypoxia-induced hepatic injury in rats was established successfully. Edema,ballooning degeneration and spotty necrosis were found in livers in the experimental groups, among which the pathological injury in the hypoxia group was worse than that in the NK-1R antagonist group. Moreover,GGT and the rate of hepatocellular apoptosis in the NK-1R antagonist group were obviously lower than that in the hypoxia group (P<0.05). But no significant difference were found in ALT,AST and ALP between groups (P>0.05). These data indicate that Substance P possibly participate in the process of hypoxia-induced hepatic injury, and NK-1R antagonist could reduce hypoxia-induced hepatic injury.
