Summary
The effects of metopirone and aldactone on the histology of the pars distalis of the pituitary, the interrenal gland and the interstitial tissue of the testis were studied in male common frogs. Activation of the interrenal tissue by these substances was paralleled by a stimulation of one of the tinctorial cell types in the distal lobe namely the basophils 3 and of caudal chromophobic cells. Simultaneously a regression of the interstitium testis was observed. It is suggested that either the basophils 3 or the caudal chromophobic cells have a corticotropic function.
