摘要
The present experiment employed the immunohistochemical technique and morphological observation to investigate the expression and distribution of C3, C4, IgG, IgE and 5-HT in portal hypertensive pigs with pathological change of gastric mucosa and gastric parietal vessels. The wall of gastric mucosal microvessels in portal hypertensive pigs had a positive or strong positive reaction of C3,C4, IgG, IgE and 5-HT with obvious injury of gastric mucosa normal pigs imparted negative or feeble positive reaction, suggesting that during portal hypertension, the gastric mucosal micr0-vessels has deposit of immunocomplexes resulting in the injury of the micro-vessels. It might be a factor inv01ved in the pathogenesis of the gastric mucosal lesion during portal hypertension with cirrhosis.
