[Recovery processes in rabbit spleen after hydrocortisone administration].

The effect of hydrocortisone on the rabbit spleen and the recovery processes after the cessation of the hormone injection was studied. A decrease of the absorption function of RES, and spleen atrophy, expressed in a decrease of the organ weight and size followed prolonged hydrocortisons use. Most of the spleen nodes were reduced to an irregular accumulation of lymphocytes. The pyroninophilic cells disappeared in the white pulp. Cessation of the hormone effect was followed by an improvement in the general condition of the animal; the development of the spleen atrophic processes was suspended, the spleen nodes were restored with an increase of pyroninophilic cell count in them. The use of a stimulant under these conditions accelerated the recovery of the animal weight, as well as that of the atrophic spleen, with a normalization of the organ structure.
