ABSTRACT The effects of ethanol leaf-extract of Albizia ferruginea on haematological indices were investigated in albino rats using standard methods. Twenty four albino rats were randomly placed into four experimental groups (A, B, C and D) after seven days of acclimatization with six rats in each group. Animals in groups A, B, C and D were administered the ethanol leaf-extract of Albizia ferruginea at the doses of 0, 200, 400 and 600 mg/kg body weight respectively twice daily for fourteen days through oral intubation. The results showed that haemoglobin (Hb) level, Packed Cell Volume (PCV), red blood cell (RBC) count and white blood cell (WBC) count increased significantly (p<0.05) and dose-dependently. The results suggest that the ethanol leaf-extract of Albizia ferruginea could be effective in the management of anaemia. Key words: Albizia ferruginea, leaf-extract, haematological indices, albino rats. INTRODUCTION Plants of various origins have been Albizia ferruginea is a perennial tree exploited effectively over many with about 45m high and 3m girth. The generations for therapeutic purposes [1] leaves are bipinnate with pinnae and have long been the principal tools exceeding sometimes seven pairs. It is a of traditional medicinal system as species of plant in the Fabaceae family, medicinal plants are part of human found in Angola, Benin, Cameroon, society to combat diseases since Republic of Congo, Nigeria, Senegal, civilization evolved [2].

MATERIALS AND METHODS month of February while the adult male Materials albino rats were gotten from the animal house of Department of Veterinary The fresh leaves of Albizia ferruginea Medicine, University of Nigeria, Nsukka. were collected from Umuezeoka, Ezza North L.G.A. of Ebonyi State in the METHODS Exactly 300g of the powdered sample Extraction of Plant Material was soaked in 1200l of ethanol and allowed to stand for 48 hours. It was The leaves of the plant were rinsed in then filtered using a muslin cloth and tap water and dried. The dried leaves concentrated by evaporation to dryness were ground using a milling machine. using rotary evaporator 75 IDOSR JOURNAL OF SCIENCE AND TECHNOLOGY 3(1): 74-81, 2018. www.idosr.org Ukpabi et al . Administration of the Extract Collection of Blood Samples The experimental animals were placed The blood samples were collected into four (4) groups (A, B, C and D) of six through the femoral vein.

DISCUSSION AND CONCLUSION The ethanol leaf-extract of Albizia elevation in haemoglobin, PCV, WBC and ferruginea significantly (p<0.05) and RBC in rats administered with ethanol dose-dependently increased the leaf-extract of Moringa oleifera.
