Effects of Proanthocyanidins on Intestinal Motility Disturbance Following Intestinal Ischemia/Reperfusion.

Purpose: To investigate the potential protective effects of Proanthocyanidins(PAs) on intestinal motility disturbance following intestinal ischemia/reperfusion (I/R).

Materials And Methods: Male rats were divided into four groups: Sham, I/R, I/R+PA100 and I/R+PA200. Sham group underwent laparotomy without ligation, the others were subjected to intestinal ischemia for 1 h and reperfusion 4 h.

Comparison of different methods of intestinal obstruction in a rat model.

Aim: To investigate different methods of creating incomplete intestinal obstruction in a rat model and to compare their electrophysiologic, morphologic and histologic characteristics.

Methods: Rat ileum was partially obstructed by the respective application of: braided silk (penetrated the mesentery and surrounded intestine); half ligation (penetrated directly and ligated 1/2 cross-section of the intestine); wide pipe (6 mm in width, surrounded the intestine); narrow pipe (2 mm in width, surrounded the intestine). A control was also included (no obstruction).
