To investigate the effects of carbachol injection in intestine on plasma levels of tumor necrosis factor-alpha(TNF-alpha), interleukin-10 (IL-10) and cortisol in rats during gut ischemia/reperfusion.
Wistar rats were anaesthetized with soluble pentobarbitone, and subjected to superior mesenteric artery occlusion (SMAO) for 60 minutes, followed by reperfusion for 60 minutes. Animals were divided into three groups, pretreated group (carbachol injection in intestine at 30 minutes after SMAO; 0.1 mg/kg), treated group (carbachol injection at 30 minutes from onset of reperfusion), and controls (saline injection). Plasma TNF-alpha, IL-10 and cortisol levels were determined at 1.0, 2.5 and 6.0 hours after SMAO.
The plasma levels of TNF-alpha significantly decreased in pretreated and treated groups than those in controls after carbachol injection (both P<0.01). However, the levels of IL-10 and cortisol didn't show significant differences among three groups.
The RESULTS suggest that carbachol can reduce the proinflammatory cytokine release and have a less inhibitory effect on the anti-inflammatory cytokine. It is indicated that carbachol play a potential role in alleviating systemic inflammatory response during splanchnic ischemia/reperfusion injury.
