Morphology, histology, and immunohistochemistry of the adrenocortical and adrenomedullary homologs (adrenal glands) of the following developing and adult teleosts were examined: Salmoniformes-Oncorhynchus mykiss (rainbow trout), Salmo trutta fario (brown trout), Coregonus lavaretus (white fish); Cyprinodontiformes-Gambusia affinis (mosquito fish).(More)
Organotypic cultures were made of right female gonads of chick embryos of 8 days, on medium containing follicle-stimulating hormone, luteinizing hormone or prolactin (PRL), and of left ovaries of the same age on the medium containing PRL. Results indicate that the explants cultured on PRL resemble most closely the normal ovaries in vivo. It is suggested(More)
The adrenal gland in Rana esculenta complex, as in other advanced anurans, is not yet in its definitive position at the end of the metamorphosis and reaches it subsequently, before sexual maturity. The displacement takes place by various means, among which active cellular movements prevail. These are demonstrated by the presence of acetylcholinesterase(More)
Adrenal glands of three species of Euproctus (E. asper, E. montanus and E. platycephalus) were compared. Differences were observed as regards: (1) the distribution of the adrenal tissue, which is more sparse in E. asper than in the other two species; (2) the amount and size of the adrenal islets: in E. asper, they are numerous and small, in E.(More)
