Abstract/OtherAbstract:
The aim of the study was to investigate CRF- and neurophysin-immunoreactive neurocytes in hypothalamo-pituitary system of the hamster. CRF-immunoreactive nerve fibers were observed mainly in the outer layer of the median eminence and pituitary stalk and also in the neurohypophysis. On the contrary, neither intermediate lobe nor anterior pituitary contained CRF-immunoassayable substance. The pattern of distribution of neurophysin-immunoreactive fibres was different from CRF-immunoreactive fibres as far as a median eminence, pituitary stalk and neurohypophysis are concerned. Between the tannocytes of the III ventricle and nervous fibres forming the internal layer of the median eminence a CRF- and neurophysin-immunoreactive perikaryons of neurocytes were found. Results of the study suggest regulatory function of CRF-immunoreactive neurons of the hamster hypothalamo-pituitary system in controlling of ACTH secretion. Moreover, the distribution of CRF-immunoreactive substances in hamster hypothalamo-pituitary system shows some peculiarities if compared with other rodents.
