The current study was carried out to assess in vitro and in vivo effects of seed methanolic extract on to develop an alternative source of treatment. The in vitro ovicidal effect of seed extract on immature eggs has provided evidence of inhibitory activity on the vitality and hatchability of eggs. This inhibitory activity was concentration-dependent and also correlated strongly with the exposure time. In the in vivo trial, the oral administration of experimentally infected rabbits with doses of 150 mg/kg BW prepared extract per day for 3 consecutive days on the 63rd day post infection confirmed potent fasciolicide activity of the extract. A gradual decrease in fecal egg count (FEC) was detected from the 1st day post treatment until reaching 100% FEC reduction by the 7th day post treatment. No flukes could be found at post mortem examinations. Significant increments of serum total protein, globulin, the activities of ALT and AST, total cholesterol, triglycerides and urea were recorded during the period of infection, which were improved by treatment. Remarkable histopathological alterations were observed in the infected liver and gallbladder tissues which decreased clearly in the treated rabbits. This study proposes that the used extract has promising and potent fasciolicide activity.
本研究旨在评估种子甲醇提取物的体外和体内效应,以开发一种替代治疗来源。种子提取物对未成熟虫卵的体外杀卵作用为其对虫卵活力和孵化率的抑制活性提供了证据。这种抑制活性呈浓度依赖性,且与暴露时间也密切相关。在体内试验中,在感染后第63天,对实验感染的兔子连续3天每天口服150 mg/kg体重的制备提取物,证实该提取物具有强大的杀片形吸虫活性。从治疗后第1天开始检测到粪便虫卵计数(FEC)逐渐下降,到治疗后第7天FEC下降达到100%。尸检未发现吸虫。在感染期间,血清总蛋白、球蛋白、谷丙转氨酶(ALT)和谷草转氨酶(AST)活性、总胆固醇、甘油三酯和尿素显著升高,治疗后有所改善。在感染的肝脏和胆囊组织中观察到明显的组织病理学改变,在治疗的兔子中明显减轻。本研究表明,所用提取物具有良好且强大的杀片形吸虫活性。
