(family: ), has been harnessed and utilized for treatment of several ailments. However, there is the paucity of available data on nephrotoxicity associated with this herb. Here, we investigated the phytochemical profile and toxicological effect of on Wistar Rats.
Twenty rats (weight range: 75-100 g) were assigned into five study groups, viz; (a) control (without treatment) (b) treatment group 1, orally administered with 50 mg/kg (c) treatment group 2, orally administered with 100 mg/kg (d) treatment group 3, orally administered with 250 mg/kg, and (e) treatment group 4, orally administered with 300 mg/kg of respectively for 28 days of four rats per group. The rats were made unconscious by using oral administration of chloroform. Cardiac punctures were made, and blood samples collected into 10 ml labeled plain container, allowed to clot and spun to harvest serum for determination of sodium, potassium, chloride, bicarbonate, urea and creatinine using colorimetric, back-titrimetric, Urease-Berthelot and Jaffe's reaction methods respectively. Kidneys of rats were harvested, weighed and immediately fixed in 10% neutral buffered formalin for histological analysis.
Mean serum sodium (p = 0.049), potassium (p = 0.007), and urea (p < 0.001) levels were significantly higher among the treatment groups compared to controls. Histopathological findings of kidney sections revealed mild glomerular infiltration in treatment groups 2-4. Additionally, sclerosis was observed in groups 3-4. Phytochemical analysis of revealed presence of alkaloids, flavonoids, saponins, tannins, terpenoids, steroids and reducing sugars.
From the findings in this study, leaf extract causes significant damage to the kidneys of Wistar rats at higher doses. Of which, the damages were dose-dependent in direct proportionality manner. To better determine the safe dosage and ideal duration of consumption, there is the need for further studies on
(科属: ),已被用于治疗多种疾病。然而,关于这种草药相关肾毒性的可用数据很少。在此,我们研究了 对Wistar大鼠的植物化学特征和毒理学作用。
将20只大鼠(体重范围:75 - 100克)分为五个研究组,即:(a)对照组(未治疗)(b)治疗组1,口服50毫克/千克 (c)治疗组2,口服100毫克/千克 (d)治疗组3,口服250毫克/千克 ,以及(e)治疗组4,口服300毫克/千克 ,每组4只大鼠,持续28天。通过口服氯仿使大鼠失去意识。进行心脏穿刺,将血液样本收集到10毫升标记的普通容器中,使其凝固并离心以获取血清,分别使用比色法、返滴定法、脲酶 - 伯特洛法和杰氏反应法测定钠、钾、氯、碳酸氢盐、尿素和肌酐。收获大鼠的肾脏,称重并立即固定在10%中性缓冲福尔马林中进行组织学分析。
与对照组相比,治疗组的平均血清钠(p = 0.049)、钾(p = 0.007)和尿素(p < 0.001)水平显著更高。肾脏切片的组织病理学检查结果显示,治疗组2 - 4有轻度肾小球浸润。此外,在第3 - 4组中观察到硬化。对 的植物化学分析显示存在生物碱、黄酮类、皂苷、单宁、萜类、类固醇和还原糖。
根据本研究的结果, 叶提取物在高剂量时会对Wistar大鼠的肾脏造成显著损害。其中,损害呈剂量依赖性的正比关系。为了更好地确定安全剂量和理想的食用时长,有必要对 进行进一步研究
