10.22376/ijpbs.2019.10.1.p1-12 Volume 3 Issue 4 2012(October - December) Medicines play an important role in human health cure. The plant kingdom constitutes a source of new chemical compounds which may important owing to their potential use in medicine and other applications. The present study investigates the hematopoietic activity of lessThan i greaterThan Beta vulgaris lessThan /i greaterThan in experimental rat models treated with various concentrations of the methanolic extract of the root of lessThan i greaterThan Beta vulgaris. lessThan /i greaterThan  Rats were divided into four groups of five each and the groups were as follows: Group 1- Control group; Group 2- Rats were received 100 mg/kg b.w. lessThan i greaterThan Beta vulgaris lessThan /i greaterThan methanolic lessThan i greaterThan lessThan /i greaterThan extract orally for sixteen days; Group 3- Rats were received 200 mg/kg lessThan i greaterThan Beta vulgaris lessThan /i greaterThan methanolic lessThan i greaterThan lessThan /i greaterThan extract orally for sixteen days; Group 4- Rats were received 400mg/kg lessThan i greaterThan Beta vulgaris lessThan /i greaterThan methanolic lessThan i greaterThan lessThan /i greaterThan extract orally for sixteen days. All the groups were given lessThan i greaterThan Beta vulgaris lessThan /i greaterThan extract for sixteen days at 24 hour interval. From the Phytochemical studies it was proved that powdered root of lessThan i greaterThan Beta vulgaris lessThan /i greaterThan contains alkaloids, flavonoids, phenols etc., In this study rats treated with methanolic root extract of lessThan i greaterThan Beta vulgaris lessThan /i greaterThan recorded significant increase s in Packed Cell Volume (PCV), Hemoglobin concentration, Red Blood Cell counts (RBCs), and Total lymphocyte count .The other parameters such as MCV, MCH, MCHC also showed a dose dependent fashion.
