Abstract

The protective effects of the leaf powder of Picralima nitida in male rats were evaluated to establish its haematopoietic potential. To achieve this, albino rats (n = 30), weighing 120 - 160g were grouped into 5, labelled A to E. Groups C and D were intraperitoneally induced for anaemia with 0.1mg/kg body weight (b.wt) of phenyl hydrazine for 7 day. Groups A and B and C and D orally received 200 and 400 mg/kg b.wt of Picralima nitida leaf extract respectively for 14 days. Group E served as the control. Blood sample (5.0ml) was collected from each rat on days 8 and 15 and dispensed into ethylene diamine tetra acetic acid containers for haemogram using haematology auto analyser. The result showed that on day 8, Picralima nitida leaf extract produced a significant (P<0.05) increase in haemoglobin (Hb) and haematocrit (Hct) when compared with the control. On day 15, Picralima nitida leaf extract produced a significant (P<0.05) increase in the red blood cell (RBC), Hb and Hct when compared with the experimental control. The results indicate time-dependent haematopoiesis.

摘要

为了评估 Picralima nitida 叶粉对雄性大鼠的保护作用，以确定其造血潜能。为此，将 30 只体重为 120-160g 的白化大鼠(n=30)分为 5 组，分别标记为 A 至 E。第 C 组和第 D 组通过腹腔注射 0.1mg/kg 体重的苯肼诱导贫血，共 7 天。第 A 组和第 B 组及第 C 组和第 D 组分别口服 200 和 400mg/kg 体重的 Picralima nitida 叶提取物，共 14 天。第 E 组作为对照。第 8 天和第 15 天，从每组大鼠采集 5.0ml 血样，并置于乙二胺四乙酸容器中，使用血液自动分析仪进行血常规检查。结果表明，与对照组相比，Picralima nitida 叶提取物在第 8 天显著增加了血红蛋白(Hb)和血细胞比容(Hct)(P<0.05)。第 15 天，与实验对照组相比，Picralima nitida 叶提取物显著增加了红细胞(RBC)、Hb 和 Hct(P<0.05)。结果表明，这是一种时间依赖性的造血作用。
