Effect of n-hexane leaf extract of Ipomoea batatas L. on myeloid–erythroid cells in albino rats. (1) showed the control rat bone marrow composed of A—megakaryocyte, B—bone, C—myelo-erythroid cells, and D—fat vacuoles, (2) phenylhydrazine alone showed moderately decreased A—marrow, B—fat ratio and C—bone trabecula, (3) at 5 mg/kg of ferrous (iii) hydroxide, the results showed normal A—marrow, B—fat ratio, (4) at 125 mg/kg n-hexane leaf extract, our results showed moderately increased A—marrow, and B—fat ratio (5) at 250 mg/kg n-hexane leaf extract, the result found a moderately increased A—marrow and B—fat ratio (6) at 500 mg/kg n-hexane leaf extract, the result observed a moderately increased A—marrow and B—fat ratio, using haematoxylin–eosin dye with X 40 magnification
