 AB    OBJECTIVE: To further investigate the capacity of Li to influence the
       hematopoietic toxicity of AZT. METHODS: Normal mice (C57BL/6) received
       dose-escalation AZT (0.1 and 2.5 mg/ml, i.p.) respectively for
       four-weeks with added Li2CO3 (1 mM). Li was stopped followed by a
       continuous 4-week period of AZT. Mice were evaluated on a weekly basis
       for their hematological toxicity by measurement of peripheral blood
       indices and progenitor cells from marrow and spleen for the eight-week
       study period. RESULTS: AZT induced dose-dependent toxicity that was
       measured by reduced indices and progenitor cells from marrow and spleen;
       however, in the AZT groups receiving Li, toxicity was reduced
       significantly (P value < 0.05) not only during the course of combined
       AZT and Li, but more importantly, the ability of Li to influence AZT
       toxicity carried over in the groups that had previously received Li and
       now had received only AZT compared to AZT controls.
       DISCUSSION/CONCLUSIONS: Use of Li provides an effective treatment to
       minimize AZT toxicity with lasting effects.
