The purpose of this study was to observe the antitumor effect and toxic and side effect of lithium carbonate (Li 2CO 3) on cyclophosphamide (CP). All mice were inoculated tumors(hepatocarcinoma H 22 or sarcoma S 180 )according to the standard method. Li 2CO 3 20 or 40 mg/(kg.d) was administered for 10 days. CP(90 or 180 mg/kg) was administered once by ip. It was shown that combinated application of Li 2CO 3 and CP significantly enhanced the inhibition rates of tumors (H 22 , S 180 ) in mice, and remarkably increased the number of white blood cell (WBC) of the tumor bearing mice (H 22 , S 180 ), and remarkably decreased the frequency of micronucleus (MNF) of bone marrow polychromatic erythrocyte (PCE) of the tumor bearing mice. These results indicated that Li 2CO 3 could enhance significantly the effects of CP to inhibite tumor in mice, and remarkably reduce the toxic and side responses of decreasing WBC and increasing MNF caused by CP.
