Ultrastructure of adrenal medulla of the prenatal rat.
The ultrastructure of the adrenal medulla in adult laboratory animals has been described in a number of reports (Lever, 1955; Sjostrand & Wetzstein, 1956; Wetzstein, 1957; de Robertis & vaz Ferreira, 1957; Eranko & Hanninen, 1960; Yates, 1963,1964a, b, c; Coupland, 1965 a, b; Elfvin, 1965 a, b). Since the introduction of the glutaraldehyde fixation technique, it has been possible to distinguish...
متن کاملLong-term survival of autologous adrenal medulla grafts in the great omentum of the rat.
The omentum, a rich source for trophic and angiogenic factors, was explored as a potential intermediate transplant site to facilitate long-term survival of chromaffin tissue. Autologous rat adrenal medullas were grafted into omental pockets. All grafts became densely vascularized. The grafted chromaffin tissue exhibited strong immunoreactivities for tyrosine hydroxylase, synaptophysin and chrom...
متن کاملMaturation and long-term hypoxia alters Ca2+-induced Ca2+ release in sheep cerebrovascular sympathetic neurons.
The contribution of sympathetic nerves arising from the superior cervical ganglia (SCG) toward the growth and function of cerebral blood vessels is pertinent throughout maturation as well as in response to cardiovascular stress imposed by high-altitude long-term hypoxia (LTH). The function of SCG sympathetic neurons is dependent on intracellular Ca2+ concentration ([Ca2+]i) signaling, which is ...
متن کاملScopical Studies of the Prenatal Adrenal Medulla in Spontaneously Hypertensive Rat
graphical grain count per labeled cell on the 20th day of gestation didn't differ from that on the 22nd day of gestation. These results indicate that the generation time of the adrenal medullary cell in SHR became more longer on successive day of gestation. However, there was no significant difference of the histology and histoautoradiography between SHR and control. Ultrastructurally, most of ...
متن کاملAsthma Pregnancy Alters Postnatal Development of Chromaffin Cells in the Rat Adrenal Medulla
BACKGROUND Adrenal neuroendocrine plays an important role in asthma. The activity of the sympathoadrenal system could be altered by early life events. The effects of maternal asthma during pregnancy on the adrenal medulla of offspring remain unknown. METHODOLOGY/PRINCIPAL FINDINGS This study aims to explore the influence of maternal asthma during pregnancy on the development and function of a...
