Abstract

Plasmodium parasite causes malaria and affects the biochemical, physiological, and histoarchitecture of the hepatocytes and blood. The resultant effect leads to alterations in the metabolic activities of the liver, erythrocytes, as well as the buffer system. Therefore, we investigated the antiplasmodial activity, histomorphological studies of the hepatocytes and alterations in biochemical parameters in infected mice administered with the herbal formulation of aqueous extracts of stem bark and leaves. The plant coarse leaves (250.71 g) and stem bark (509.34 g) were weighed to obtain their ratios, macerated in boiled distilled water (5 L) for 72 h, filtered, and concentrated to obtain the various extracts whereas LD calculation gave 5500.19 mg/kg. The extracts were administered to eleven groups of mice at a dosage of 300 mg/kg whereas artesunate and ACT served as the positive control drugs; the antiplasmodial profiling, biochemical, and histological evaluations followed standard protocols. The schizonticidal activity of the extracts were remarkable; moreover, the histological section of the liver (negative control) had increased deposition of hemozoin, sinusoidal congestions, activation of kupffer cells, and portal tract inflammations; however, the other treatment groups in the study drastically reduced inflammation. The biochemical parameters' results revealed metabolic acidosis mitigation; hypocholesterolemia induction; enhanced hyperproteinemia, as well as hypoglycemia mitigation. The antiplasmodial therapeutic response, and biochemical derangements reversal corroborated with improved hepatocytes histoarchitecture of mice highlights the plant's pharmacological efficacy.

摘要

疟原虫会引发疟疾,并影响肝细胞和血液的生化、生理及组织架构。其最终影响会导致肝脏、红细胞以及缓冲系统的代谢活动发生改变。因此,我们研究了用茎皮和树叶水提取物的草药配方处理的感染小鼠的抗疟活性、肝细胞组织形态学研究以及生化参数的变化。称取植物粗叶(250.71克)和茎皮(509.34克)以获得它们的比例,在煮沸的蒸馏水(5升)中浸泡72小时,过滤并浓缩以获得各种提取物,而半数致死量计算得出为5500.19毫克/千克。以300毫克/千克的剂量将提取物给予11组小鼠,而青蒿琥酯和蒿甲醚作为阳性对照药物;抗疟分析、生化和组织学评估遵循标准方案。提取物的裂殖体杀灭活性显著;此外,肝脏组织切片(阴性对照)出现疟色素沉积增加、窦状充血、库普弗细胞活化和门管炎症;然而,研究中的其他治疗组炎症大幅减轻。生化参数结果显示代谢性酸中毒减轻;诱导低胆固醇血症;高蛋白血症增强以及低血糖减轻。抗疟治疗反应和生化紊乱的逆转与小鼠肝细胞组织架构的改善相一致,突出了该植物的药理功效。
