THE IN VITRO ACTION OF HYDROCORTISONE ON LEUCOCYTE MIGRATION

Hydrocortisone inhibits the ameboid migration of human leucocytes when added in vitro. The dose-response curve for the reaction between this steroid and leucocytes can be best expressed by a logarithmic plot of the steroid concentrations. Tetrahydrocortisone and desoxycorticosterone had no effect on in vitro leucotyte migration.
