Abstract
目的:从胃黏膜表面pH值、组织病理学变化及胃黏膜酶组化角度研究并探讨慢性胃炎肝胃气滞、脾胃气虚及脾胃湿热3种证型演变规律及证的物质基础.方法:60例慢性胃炎3种证型患者胃镜下取胃黏膜活检组织,用精密试纸检测胃黏膜表面pH值,冰冻切片酶组化法显示琥珀酸脱氢酶(SDH)、乳酸脱氢酶(LDH)及碱性磷酸酶(ALP)酶活性,石蜡切片HE及AB-PAS染色光镜观察胃黏膜组织病理学变化及黏液分泌状态.结果:3种证型胃窦黏膜表面pH值分别为:肝胃气滞(5.65±0.24)、脾胃湿热(5.43±0.05)、脾胃气虚(5.49±0.06),差异无统计学意义;胃窦黏膜SDH(-)及弱(+)面积从多至少排序为:脾胃气虚、脾胃湿热、肝胃气滞;肠化部位SDH酶活性相对较强,萎缩部位则较弱或呈(-);3种证型均未见LDH完全(-)病例,脾胃气虚及脾胃湿热证亦未见LDH弱(+)病例,肝胃气滞证仅见2例弱(+);肠化部位LDH活性强于或近似于非肠化区;脾胃气虚证ALP(-)及(+)面积明显多于脾胃湿热和肝胃气滞证,中强(+)面积明显少于肝胃气滞证和脾胃湿热证.结论:胃黏膜酶的分布及其活性变化是慢性胃炎辨证及证型演变的物质基础.
