ABSTRACT
Objective To investigate the protective effect of pinacidil on the intestinal mucosa of scalded rats and the mechanism. Methods A total of 24 healthy SD rats were randomly divided into normal control group, burn group, and pinacidil treated group. Rats in burn group and pinacidil treated group were inflicted with 30% TBSA Ⅲ degree burn and resuscitated intraperitoneally with Ringer's solution immediately after burn. Pinacidil was injected intraperitoneally into rats in pinacidil treated group at the dose of 2 mg/kg. Mitochondrial respiratory function intestinal mucosa and levels of reactive oxygen species (ROS), maleic dialdehyde (MDA), and superoxide dismutase (SOD) in plasma were determined at 6 h after burn. Results Mitochondrial respiratory function control rate (RCR), ST3, and SOD levels in pinacidil treated group were evidently higher than those in the burn group. However, ST4, MDA, and ROS levels in pinacidil treated group were significantly lower than those in the burn group, but ST4 was not significantly different from that in the normal control. Conclusion Pinacidil can attenuate the damage of intestinal mucosa in scalded rats.
