文题释义:
肝硬化:是由于一种或多种病因长期或反复作用于肝脏,通过炎症途径诱导肝细胞大量坏死、再生,细胞外基质过度沉积,最终导致纤维间隔形成和假小叶形成,门静脉高压和肝功能降低的终末期肝病,其中一部分会进展成为肝癌。
四氯化碳加乙醇复合法:是实验诱导慢性肝损伤乃至肝硬化的较为常见的一种复合因素方法。四氯化碳是诱导肝硬化的使用最为广泛的毒素之一,而乙醇又是人类酒精性肝硬化的重要致病因素,这两种因素联合在一起的复合方法既可以加速四氯化碳致肝硬化的进程,又可以模拟人类酒精性肝硬化模型,是一种制备肝硬化动物模型的有效方法。
摘要
背景:
建立稳定、可靠、易操作又高效的肝硬化动物模型是进行肝硬化防治研究的前提条件。
目的:探寻一种理想的CCl4诱导大鼠肝硬化模型的造模方法。
方法:将Wistar大鼠随机分为正常对照组(n=8)、模型A组(n=21)及模型B组(n=21),正常对照组左右腹部皮下交替注射橄榄油,每4 d一次;模型A组用传统型方法,左右腹部皮下交替注射3 mL/kg 50%CCl4橄榄油溶液,每4 d一次,以10%乙醇溶液(以二锅头白酒、蒸馏水配制)为其惟一饮用水;模型B组用改良的CCl4加乙醇复合法诱导大鼠肝硬化模型,左右腹部皮下交替注射50% CCl4橄榄油溶液,最初4次及最末3次剂量为5 mL/kg,其余为3 mL/kg,每4 d一次,以乙醇溶液(以二锅头白酒、蒸馏水配制)为其惟一饮用水,乙醇浓度从5%逐渐过渡为10%。造模时间9周。
结果与结论:与正常对照组相比,模型A、B组大鼠体质量增加缓慢,与模型A组相比,模型B组体质量波动较小。模型A、B两组丙氨酸氨基转移酶和天门冬氨酸氨基转移酶均明显高于正常对照组,模型B组丙氨酸氨基转移酶水平高于模型A组,而模型A、B两组天门冬氨酸氨基转移酶水平差异无显著性意义。模型B组与正常对照组存活率差异无显著性意义,且模型B组比模型A组假小叶形成率高。提示用改良的CCl4加乙醇复合法造模的大鼠肝硬化模型死亡率低且成模率高。

Abstract:

BACKGROUND: Establishing a stable, reliable, easily handling and highly efficient animal model of liver cirrhosis is the prerequisite for the study on the prevention and treatment of the disease.
OBJECTIVE: To establish and evaluate an ideal means to induce liver cirrhosis in rats by carbon tetrachloride (CCl4).
METHODS: Wistar rats were randomly allotted into control group (n=8), group A (n=21) and group B (n=21). Olive oil was injected subcutaneously into both sides of the abdomen of control rats every 4 days; in the group A, 50% CCl4 in olive oil was injected subcutaneously into the abdomen with a dosage of 3 mL/kg every 4 days, and a 10% ethanol solution (Erguotou liquor and distilled water) constituted the only liquid drank; in the group B, 50% CCl4 in olive oil was injected subcutaneously into the abdomen every four days, the first four and final three doses were 5 mL/kg, and the other doses were 3 mL/kg, and a gradually transition from 5% to 10% ethanol solution (Erguotou liquor and distilled water), constituted the only liquid drank. The modeling time was 9 weeks.
RESULTS AND CONCLUSION: There was a slower increase in the rat body mass in the groups A and B compared with the control group, especially in the group B. The serum levels of alanine aminotransferase and aspartate aminotransferase in the groups A and B were significantly higher than those in the control group. The level of alanine aminotransferase in the group B was significantly higher than that in the group A, but there was no significant difference in the aspartate aminotransferase level between the groups A and B. The cirrhosis with pseudolobules rate and success rate in the group B were higher than those in the group A. There was no significant difference in survival rate between group B and control group. That is to say, the improved method of inducing cirrhotic model in rats by CCl4 combined with ethanol shows a high rate of success and a low rate of mortality.
