The protective effects of Mentha piperita (Linn) extract against radiation induced hematopoietic damage in bone marrow of Swiss albino mice have been studied. Mice were given either double distilled water or leaf extract of M. piperita orally (1 g/kg b.wt./day) once a day for three consecutive days, and after 30 min of treatments on the third day were exposed to 8 Gy gamma radiation. Mice were autopsied at 12, 24, 48 hrs and 5, 10 and 20 days post-irradiation to evaluate the percentage of bone marrow cells, frequency of micronuclei and erythropoietin level in serum. An exposure to gamma radiation resulted in a significant decline in the number of bone marrow cells such as leucoblasts, myelocytes, metamyelocytes, band/stab forms, polymorphs, pronormoblasts and normoblasts, lymphocytes, and megakaryocytes. Pretreatment with leaf extract of M. piperita followed by radiation exposure resulted in significant increases in the numbers of leucoblasts, myelocytes, metamyelocytes, band/stab forms, polymorphs, pronormoblasts and normoblasts, lymphocytes, and megakaryocytes in bone marrow as compared to the control group. Pretreatment with leaf extract of M. piperita followed by radiation exposure also resulted in significant decreases in micronucleus frequencies in bone marrow of Swiss albino mice. A significant increase in erythropoietin level was observed at all the studied intervals in leaf extract of M. piperita pretreated irradiated animals as compared to control animals (radiation alone). The results of the present investigation suggest the protective effects of leaf extract of M. piperita against radiation induced hematopoietic damage in bone marrow may be attributed to the maintenance of EPO level in Swiss albino mice.
