  • Abstract
  • Look Inside

The effects of anticonvulsants on cellular im-munity were examined in murine models. Fresh splenocytes were obtained from mice which had been intraperitoneally given 1 mg of phenytoin, 2 mg of phenobarbital, or 20 mg of valproate for 28 days. The serum concentration of phenytoin, phe-nobarbital and valproate in these animals were 10-20 μg/ml, 30-40 μg/ml and 50-70μg/ml, respec-tively. The proliferative response of splenocytes to mitogens was assessed by 3H-thymidine incor-poration. The cytotoxic activities of cells such as natural killer (NK) cells, cytotoxic T lymphocytes (CTL), and lymphokine-activated killer (LAK) cells were estimated by a 4 hr-51Cr release assay. Phenytoin suppressed lymphocyte proliferation, NK activity, and CTL activity, but never LAK activity. Phenobarbital suppressed proliferative response to rIL-2 and CTL activity, but did not suppress NK activity nor LAK activity. In turn sodium pyruvate never suppressed any activity on cellular immunity.
