摘要 为探讨血清溶菌酶,补体活性与急性胰腺炎病变程度的关系,本实验以30只健康成年犬为动物模型,采用自身胆汁以不同压力和持续时间灌注犬胰管,观察由此所造成的急性胰腺炎在严重程度上有何不同。结果显示:水肿性与坏死性组于灌注后24h起血清溶菌酶与对照比较明显升高(P<0.01),坏死性组总补体活性与对照和水肿性比较则明显下降(P<0.01),提示血清溶菌酶,补体活性在急性胰腺炎的发病机理中具有一定的作用。

Abstract This study was to observe the relationship of serum lysozyme and complement activities with severify of acute pancreatitis.30 healthy adult dogs were used as experimental animals.The severity of acute pancreatits caused by autobile perfusing pancreatic duct of dog with different pressure and time was studied.The results showed that serum lysozyme of edematous group and necrotic group raised at 24 hour after perfusion compared with conrtol group(P<0.01),but the complement activity in necrotic group was lower than that in conrtol group and edematous group(P<0.01).It is suggessted that serum lysozyme and complement avtivities play a significant role in the pathogenesis of acute pancreatitis.

急性胰腺炎是外科常见急腹症之一,在临床上一般将病情重,出现多器官功能受损的急性胰腺炎称急性重症胰腺炎,在病理上又将胰腺炎及周围组织出血和坏死又称急性坏死性胰腺炎,以区别普通型胰腺炎即急性水肿性胰腺炎。目前,急性重症胰腺炎尚没有一种可靠,有效的治疗方法,因此死亡率较高。近年来,大量临床资料证实急性重症胰腺炎是由急性水肿性胰腺炎加重恶化所致,经临床观察,胆源性因素在急性胰腺炎病因中占有重要地位,胆汁逆流进入胰管的压力和持续时间是决定急性胰腺炎病变程度的始动因子,即压力越大,时间越长而导致的急性胰腺炎病情越重。为了证实这种假说,本研究利用犬大体动物模型,以不同压力和持续时间将犬自身胆汁灌注胰管后诱发不同程度的急性胰腺炎,同时观察血清溶菌酶,补体活性的变化,探讨它们与急性胰腺炎病变程度的关系。
材料和方法
1 标本来源:
实验动物为本地健康成年杂种犬,雌雄不限(由成都军区总医院实验动物中心提供),共30只,体重9.5~14.3kg(11.7±3.1kg)。
2 动物分组:
实验前一周动物置相同条件下统一饲养,将30只犬随机分成五组,每组6只,一组为对照组,二组在4.0kPa压力下持续灌注犬自身胆汁入胰管2h,三组在4.0kPa下灌注6h,四组在8.0kPa压力下持续灌注犬自身胆汁入胰管2h,五组在8.0kPa下灌注6h。
