“…In addition, these mitochondria frequently contained crystalloids. Similar mitochondrial crystalloids have been reported in the inactivated interrenal cells in Rana temporaria three weeks after hypophysectomy (PEHLEMANN and HANKE, 1968), in Pleurodeles waltlii Michah two months after hypophysectomy (PIcHERAL, 1970), and in Rana catesbeiana (VARMA, 1977) administered with Metopirone, an adrenocortical inhibitor.…”

“…However, their proliferation under the influence of ACTH signifies that the lysosomal system in this species is activated in terms of steroidogenesis, either for facilitating abundant supply of substrates utilized for steroid synthesis (Elfont et al, 19791, or for disposal of excessive enzymic proteins leading to a functional modulation of the hypersecretory cortical cell. ACTH-evoked proliferation of lysosomes has been previously observed in amphibian and rat adrenals (Szab6 et al, 1967;Pehlemann and Hanke, 1968;Berchtold, 1970), and it is believed that lysosomes play a role in mobilization of lipid from their storage form (Szabb et al, 1967 …”

Distribution and structure of the adrenocortical homologue in the garpike

The microanatomy of the yellow corpuscles (adrenocortical homologue, AH) in the holostean fish, Lepisosteus spp. was studied by serial sectioning, steroid histochemistry, and electron microscopy. The modification of this tissue to short-term ACTH treatment was also observed. The distribution of the AH within the renal tissue of the garpike phylogenetically represents a more advanced condition than that seen in its closest holostean relative, the bowfin, and appears to approximate that in teleosts. The homology of this tissue of vertebrate adrenocortical tissue was established by the positive identification of the enzyme, gamma 5-3 beta-hydroxysteroid dehydrogenase, and by the ultrastructural features of the cells before and after ACTH administration. The AH cells possess fine structural features characteristic of steroidogenic cells, namely, polymorphic mitochondria with tubular cristae, abundant tubules of smooth endoplasmic reticulum, a prominent Golgi complex, and lipid droplets. Other interesting features include the presence of annulate lamellae and a variety of dense bodies. Digitonin perfusion results in the deposition of presumed, cholesterol-digitonide crystalline spicules on the surface microplicae of the cells and as dense accumulations in association with smooth endoplasmic reticulum. ACTH administration results in swelling of mitochondria, a loss of their cristae, and a smooth decrease in electron density of their matrices. Alterations also occur in the smooth and rough endoplasmic reticulum, and large osmiophilic inclusions of irregular profile appear. Some of the ACTH-induced modifications are similar to those observed in the adrenocortical cells of other vertebrate groups following comparable stimulation.

The administration of mammalian corticotrophin to larvae and adult sea lamprey, Petromyzon marinus L., results in changes in fine structure of cells within presumptive interrenal tissue located in the opisthonephric kidneys. Compared to controls, stimulated cells show increases in the volume of smooth endoplasmic reticulum, mitochondria, and the Gulgi apparatus with an accompanying decrease in numbers of lipid droplets. In addition, the plasma membrane near a perivascular space is commonly highly folded. Mitochondria are often of unusual configuration and possess "puffs" and the cristae are more tubular than in controls. The enlarged Golgi apparatus is accompanied by large numbers of coated vesicles.The morphological features of corticotrophin-stimulated presumptive interrenal cells of lampreys closely resemble the appearance of adrenocortical cells of mammals and the interrenal cells of other vertebrates after similar stimulation. These results suggest that these cells in lampreys and adrenocortical cells are likely homologs.
