Abstract:
AIM To study the effects of rh bFGF on healing quality of chronic gastric ulcer in rats. METHODS Ulcer model induced by acetic acid was established. Rats were treated with rh bFGF ig until ulcer healing and then continually treated for 10 days(30 total treatment days). The effects of rh bFGF on healing quality of chronic gastric ulcer was evaluated not only from gastric mucoal barrier tissue structure but also from gastric mucus barrier. RESULTS rh bFGF( 5 000 ～ 10 000 AU?kg -1 ) increased the thickness of regenerated gastric mucosa, lowed its abnormity degree and made its align state near to normal. rh bFGF( 2 500 ～ 10 000 AU?kg -1 ) increased collagen and capillary density in scar tissue, added mucus quantity, mucopolysaccharide layer's thickness and PGE 2 content on the surface of regenerated gastric mucosa. CONCLUSION rh bFGF has effects of promoting gastric mucosal barrier to mature, increasing the function of gastric mucus barrier and increasing the quality of ulcer healing.
