Adrenal Medulla Autografts
In 1959, experiments were begun to provide a more physiological and permanent pacemaker for chronic heart block by placing an autotransplant of either adrenal medulla or thyroid gland into the ventricular myocardium of dogs with complete heart block. The original concept was that the small area of myocardium surrounding the endocrine transplant would be stimulated by relatively high local conce...
متن کاملAvian adrenal medulla: cytomorphology and function
The purpose of this review is to explore the world literature on the avian adrenal medulla from the last 20 years. Unlike the mammalian adrenal medulla, the adrenal gland in birds has chromaffin cells mixed with cortical cells. Studies have investigated the ultrastructure (both transmission and scanning electron microscopy), biochemistry, and physiology (particularly interactions with other end...
متن کاملStereology of human fetal adrenal medulla.
Stereological studies were performed on 27 pairs of adrenal glands of human fetuses (9-38 weeks of intra-uterine development). Medullary chromaffin cells were identified by immunostaining for chromogranin-A. The volume of adrenal medulla, average cell volume, and the number of chromaffin cells were calculated. The volume of adrenal medulla increased slowly up to the 20th week and afterwards it ...
متن کاملIntracerebral adrenal medulla grafts: a review.
This review summarizes basic and clinical research on intracerebral adrenal medulla grafts, emphasizing potential applications to Parkinson's disease. Properties of intraventricular and intraparenchymal grafts are described, and cell survival and functional effects are compared. It is clear that adrenal medulla allografts survive poorly in the parenchyma of the corpus striatum and better in the...
متن کاملIsolation and characterization of the trisialogangliosides from bovine adrenal medulla.
Trisialogangliosides were isolated from bovine adrenal medulla by DEAE-Sephadex A-25 and Iatrobeads column chromatography. Their structures were elucidated by sugar analysis, neuraminidase digestion, and permethylation studies. The complete structures of trisialogangliosides, A to D, were identified as follows. A: GT1b, IV3NeuAc, II3 (NeuAc)2-GgOse4Cer. B: GT1b(NeuAc/NeuAc-NeuGc-); IV3NeuAc, II...
