摘要(Abstract):
目的 探讨丹参注射液对严重腹腔感染状态下大鼠胃粘膜血流量(GMBF)和胃粘膜内pH值(pHi)的影响。方法 将大鼠随机分为对照组、感染组和丹参组;感染组、丹参组大鼠造成肠结扎穿孔致腹腔严重感染模型;丹参组给予丹参注射液。测定穿孔前和穿孔后3、6、12、24、48h各时相大鼠GMBF及pHi。结果 与对照组比较,感染组GMBF在穿孔后3h明显降低,12h降至最低,24h开始回升,48h仍低于对照组;丹参组GMBF在6、12、24h高于感染组,pHi于穿孔后3h即有下降,6h明显低于对照组,12h下降至最低,24h有所恢复,但低于对照组;丹参组pHi在12、24、48h高于感染组。结论 严重腹腔感染状态下GMBF及pHi降低可能是引起胃粘膜屏障受损的主要原因。早期应用丹参注射液对有效预防应激性溃疡的发生有重要临床意义。
