title: [The effect of hydrocortisone and 6-methylprednisolone on the cytoplasmic membrane of rat thymocytes in an vitro system].
abstract: Hydrocortisone and 6-methylprednisolone increase the binding constant of anilinenaphthalene-sulphonate  (ANS) with the cytoplasmatic thymocytes membrane following a 2--3 hour long incubation in vitro. Over the same period these compounds stimulate the liberation of potassium ions  from the thymocytes. A supravital staining of the thymocytes with Trypan blue did not change during the whole time of the hormones action. The effect of the hydrocortisone and 6-methylprednisolone action on the ANS binding constant and potassium release depende upon the duration of incubation and concentration of the steriod in the medium. Hydrocortisone produces a greater influence than does 6-methylprednisolone.
