Biotolerance Study of the Hydroalcoholic Extract of Terminalia mantaly H. Perrier on Rat Renal Activity

Terminalia mantaly H. Perrier is one of the plants of the Combretaceae family that is widely used in traditional African medicine for its antibacterial, antifungal, and especially in the treatment of malaria. In this study, we evaluated the effect of the hydroalcoholic extract of Terminalia mantaly (HAETM) on the tissue and kidney biochemical markers of rats. Forty (40) rats were randomly divided into 4 groups, assigning 10 animals within each group (5 males and 5 females per group). Animals in group 1 received distilled water and were used as the control group;on the other hand, groups 2, 3, 4 received by gavage a volume of the extract corresponding to 1 ml/100g body weight at 150 mg/kg, 300 mg/kg, 600 mg/kg, respectively. The hydroalcoholic extract was administered at the same time daily for 28 days, and blood was collected once a week to evaluate renal biochemical parameters;the kidney tissues were used to perform the histopathological study. The creatinine rate increased significantly (p Terminalia mantaly should be globally well tolerated by the body when used in doses ranging from 150 to 600 mg/kg of the body weight in animals (for this study, rats). However, further in-depth studies would be needed to get a more thorough and complete picture of the safety profile of the extract.

桂东常见几种绿化树种大苗育苗平衡施肥研究

研究高密度(行间距0.5m×0.5m)种植下,杜英(Elaeocarpus decipiens Hemsl)、秋枫(Bischofla javanica)、小叶榄仁(Terminalia mantaly)、蓝花楹(Jacaranda mimosifoia)、海红豆(Adenantherpavonina Linn.)和盆架子(Alstonia scholaris)6个树种绿化大苗圃地土壤理化性质变化规律,探索适合各树种绿化大苗育苗的施肥配方,为绿化苗圃科学施肥提供理论依据。结果表明:(1)各树种在梧州市生长表现良好,年均胸径生长量均高于1cm,除海红豆外,其它树种树高年均生长量均高于1m。(2)6个树种对不同矿质元素需求比例不同。(3)6个树种育苗林地土壤物理性质差别大,其中,盆架子和秋枫林地土壤偏紧,蓝花楹林地土壤紧实,对于盆架子、秋枫与蓝花楹圃地,应加强松土或多施有机肥。
