Abstract:
Objective To investigate the effects of breviscapine injection on intestinal injury induced by intestine ischemia-reperfusion(IIR). Methods 48 males SD rats with 8-week old were randomly divided into 4 groups:Sham,intestine ischemia-reperfusion(IIR),EB+IIR,TP+IIR. Breviscapine injection 20 mg/(kg·d) was given intraperitoneally in EB + IIR group. TPCA-1(12 mg/kg)was given intravenously 30 min before surgery in TP+IIR group. Rats were subjected to superior mesenteric artery occlusion consisting of 45 min of ischemia and 6 h of reperfusion;sham laparotomy served as controls. Intestine pathology was assayed by H&E staining. Con-centrations of TNF-α,IL-1β,and IL-6 in intestinal mucosa were determined by ELISA. The protein expressions of IκB-α,NF-κB ,ICAM-1of intestine tissue were assayed by western blot. Results IIR induced serious intesti-nal injury ,evidenced as poor intestine pathology ,elevation of TNF-α,IL-1β,and IL-6 levels in intestinal mu- cosa,accompanied with IκB-α/NF-κB/ICAM-1 pathway activation. However,breviscapine injection pretreatment could inhibit IκB-α/NF-κB/ICAM-1 pathway activation,leading to reduction of TNF-α,IL-1β,and IL-6 concen-trations in lung,finally attenuate ALI induced by IIR. Conclusion Breviscapine injection pretreatment could atten-uate inflammation in intestine after IIR injury via inhibiting IκB-α/NF-κB/ICAM-1signaling pathway.
