摘要目的 探讨保肝药物还原型谷胱甘肽联合甘草酸二铵对腹部开放伤后海水浸泡实验犬肝功能损伤的治疗作用.方法 致腹部开放伤后的24只犬随机分为对照组(海水浸泡1.5 h后打捞出水,单纯观察),普通治疗组(经海水浸泡后打捞出水,给予一般急救及补液处理)和保肝药物治疗组(经海水浸泡后打捞出水,给予一般急救及补液处理,同时给予保肝药物治疗),每组8只.于致伤前及致伤后定时取血测定总胆红素(TB)、血清丙氨酸转氨酶(ALT)、天冬氨酸转氨酶(AST)、乳酸脱氢酶(LDH)、凝血酶原时间(PT)、内毒素、肿瘤坏死因子-α(TNF-α)、白介素-6(IL-6),同时对肝组织进行病理检查.结果 对照组血清TB、ALT、AST和LDH明显升高,并且生存时间小于24 h.普通治疗组血清TB、ALT、AST和LDH也有明显升高,但生存时间均超过24 h.还原型谷胱甘肽联合甘草酸二铵能在伤后12～24 h内较明显减轻肝脏受损的程度.结论 还原型谷胱甘肽联合甘草酸二铵对外伤后海水浸泡导致的肝功能损伤的防治效果良好,可作为该类肝损害的首选防治方法.

abstractsObjective To investigate effect of reduced glutathione and diammonium glycyrrhizinate on the treatment of hepatic damage in experimental dogs following open abdominal injuries coupled with seawater immersion. Methods Twenty-four dogs with open abdominal injuries were randomly divided into 3 groups: the control group (given with simple observation after 1.5 h seawater immersion); the routine treatment group (given routine care and fluid transfusion after 1.5 h seawater immersion) ; the hepatic treatment group (given routine are, fluid transfusion and hepatic treatment as well, after 1.5 h seawater immersion). Each group consisted of 8 dogs. Blood samples were taken at different time points to measure total bilirubin (TB), alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), prothromin time (PT), endotoxin, tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6), and pathological examination was also made at the same time. Results For the control group, contents of TB, ALT, AST and LDH increased significantly and survival time was less than 24 hours. Contents of TB, ALT, AST and LDH of the routine treatment group also increased significantly, but survival time of all the experimental animals was mere than 24 hours. Reduced glutathione and diammonium glycyrrhizinate could reduce the extent of lesion quite significantly 12～24 hours following open abdominal injuries. Conclusions Reduced glutathione and diammonium glycyrrhizinate seemed to have good effects on the treatment and prevention against hepatic damage induced by trauma coupled with seawater immersion. It could be used as a primary means for the treatment of such kind of hepatic damage.
