Abstract

Experimental liver injury was provoked in test rats with and without spleen intraperitoneally with allyl alcohol injections. The rats without spleen were used for tests 2 months after the splenectomy. Traumatized rats received further intraperitoneal injections of Hepasor, a protoberberine alkaloid mixture from Enantia chlorantha (Annonaceae). Biochemical assays from blood plasma, serum alanine transferase, serum alkaline phosphatase, serum creatinine, serum hydroxyproline and serum calcium were done and the total amount of blood obtained by decapitation was measured. Liver and kidney samples for histological processing were taken. The biochemical results obtained show significant changes in serum hydroxyproline which increases cumulatively due to traumatization, Hepasor treatment and splenectomy. In case of spenectomy, the absolute volume of circulating blood enhanced under Hepasor treatment. The histological findings in the liver sections show that a 2-week Hepasor therapy of the 2-week pretraumatized rats greatly furthers the healing process during prolonged traumatization. The preventive effect of Hepasor was seen as a diminished occurrence of Kupffer cells, improved cell architecture and promoted mitotic activity. The sedative effect of Hepasor was pivotally evaluated, when massive intra- and extracellular damages were provoked with allyl alcohol in splenectomized rats. This indicate the high regeneration potency of Hepasor on experimentally provoked liver dysplasia.

摘要

通过腹腔注射烯丙醇,在有脾和无脾的实验大鼠中诱发实验性肝损伤。无脾大鼠在脾切除术后2个月用于测试。创伤大鼠接受进一步腹腔注射Hepasor,一种从绿花番荔枝(番荔枝科)提取的原小檗碱生物碱混合物。进行了血浆生化分析,检测血清丙氨酸转氨酶、血清碱性磷酸酶、血清肌酐、血清羟脯氨酸和血清钙,并测量断头获取的血液总量。采集肝脏和肾脏样本进行组织学处理。获得的生化结果显示,血清羟脯氨酸有显著变化,由于创伤、Hepasor治疗和脾切除术,其累积增加。在脾切除的情况下,Hepasor治疗可增加循环血液的绝对量。肝脏切片的组织学结果表明,对预先创伤2周的大鼠进行为期2周的Hepasor治疗,在长期创伤期间可极大地促进愈合过程。Hepasor的预防作用表现为库普弗细胞的发生率降低、细胞结构改善和有丝分裂活性增强。当在脾切除大鼠中用烯丙醇引发大量细胞内和细胞外损伤时,对Hepasor的镇静作用进行了重点评估。这表明Hepasor对实验性诱发的肝脏发育异常具有很高的再生潜能。
