title: Effect of AC II, an herbal formulation in cyclophosphamide-induced immunosuppression in BALB/c mice--Implication in HIV treatment.
abstract: Effect of AC II, herbal drug formulation in reducing immunosuppression caused by administration of cyclophosphamide was studied. Mice were injected cyclophosphamide (CTX) 50 mg/kg b.wt. for 14 days with or without the drug and total WBC, bone marrow cellularity and alpha-esterase positive cells were determined. On day 15, total WBC count in cyclophosphamide treated mice was 1500 +/- 420 cells/mm3, while in AC II-treated mice it was 7658 +/- 376 cells/mm3. On day 16, administration of cyclophosphamide reduced bone marrow cellularity to 3.42 +/- 0.38 x 10(6) cells/femur from the normal value of 13.83 +/- 0.96 x 10(6) cells/femur. In AC II treated group bone marrow cellularity was increased to 8.05 +/- 0.7 x 10(6) cells/femur. The number of alpha-esterase positive cells was found to be reduced to 177 +/- 25 cells per 4000 cells in CTX treated groups. But in AC II-treated group the number of alpha-esterase positive cells were raised to 843 +/- 86 cells per 4000 cells, which was closer to that of normal (710 +/- 49 cells per 4000 cells). Results indicate the usefulness of AC II to combat immunosuppression induced by chemical and biological agents.
