title: Comparative study of immunomodulating activity of Indian medicinal plants, lithium carbonate and glucan.
abstract: The protective effects of Asparagus racemosus (AR) and Tinospora cordifolia (TC) against myelosuppression induced by single doses of cyclophosphamide (CP) have been previously reported. Presented here are the results of a comparative study between AR, TC, glucan and lithium carbonate against the myelosuppressive effects of single and multiple doses of cyclophosphamide in mice. Cyclophosphamide was administered as a single dose 200 mg/kg subcutaneously to one group of mice, while a second group received 3 doses of 30 mg/kg intraperitoneally. Both groups received AR, TC and lithium orally for 15 days before CP. Glucan was administered intravenously in 3 doses, before cyclophosphamide in the first group and together with cyclophosphamide in the second group. In both groups peripheral and differential WBC counts were done before and after drug treatment and serially after cyclophosphamide injection. All four drugs produced leucocytosis with neutrophilia. When compared to control group, all 4 drugs prevented, to varying degrees, leucopenia produced by cyclophosphamide. We conclude, therefore, that both indigenous plants, AR and TC, are potent immunostimulants, with effects comparable to lithium and glucan. They need further evaluation in patients receiving cytotoxic drugs.
