title: The effect of megestrol acetate on interleukin-1 activity.
abstract: The current study investigates the effect of megestrol acetate, a synthetic progestin, on the activity of interleukin-1. Murine thymocytes were suspended in vitro and stimulated with varying concentrations of interleukin-1. [3H]Thymidine uptake was observed as an index of thymocyte proliferation. A dose-dependent increase in [3H]thymidine uptake was observed with increasing concentrations of interleukin-1. When megestrol acetate was added to the solution, a marked suppressive effect was observed. Higher doses of megestrol acetate had a greater suppressive effect on thymocyte proliferation. Additional investigation is required to further delineate the potential systemic effects of megestrol acetate.
