ABSTRACT
This study sought to explore the effects of He-Ne laser irradiation on the gastric mucosa of experimental chronic atrophic gastritis (CAG) in rat. Fifty-two male adult Wistar rats were randomly divided into five groups including normal control group, model group and three different doses He-Ne laser groups. The CAG model in rats was made by administering (per gastrogavage) a compositus liquor, including 2% sodium salicylate and 30% alcohol, for 8 weeks to stimulate the rat's gastric mucosa, combined with irregular fasting and compulsive sporting as pathogenic factors. He-Ne laser therapy was used at different doses of He-Ne laser, once a day for twenty days, then the morphological changes and the expression of cyclinD1 were observed. Compared with untreated group, the gastric mucosa of 3.36J x cm(-2) He-Ne laser group was significantly thicker (P < 0.01), the inflammatory cells of gastric mucosa were decreased (P < 0.05), the morphology, structure and volume of the cells were restored or nearly normal and the expressions of cyclinD1 were higher (P < 0.05). In a word, small dose He-Ne laser (3.36 J x cm(-2)) has a good adjuvant therapeutic effect on rat's CAG.
