Effect of Xiaokuiling prescription on the expression of HSP₇₂, HSP B in gastric mucosa of patients with helicobacter pylori-associated duodenal ulcer

Abstract

In order to investigate the mechanism of Xiaokuiling prescription (XKL) in the treatment of Helicobacter pylori (HP)-associated duodenal ulcer (DU) and the pathophysiologic role of heat shock proteins (HSPs) in the healing of ulcer, the expression of HSP₇₂ and HSP B in gastric mucosa was detected by using SABC immunohistochemistry method and processed by micro-image analysis system. The method of Western blotting was used to measure the contents of HSP₇₂ and HSP B in the tissue emulsion of gastric mucosa. The results were as follows: (1) HSP₇₂ expression of the gastric mucosa in the treated group was obviously increased as compared with that in the control group (P<0. 05); (2) HSP B expression of the gastric mucosa in the treated group was significantly decreased as compared with that in the control group (P<0. 01). It was suggested that the increased expression of HSP₇₂ and the elimination of HP might be related to the mechanism of action of XKL. HSPs might play an pathological and physiological role in the process of healing of gastric ulcer.
