摘要: Somatostatin, insulin and glucagon were localized in the principal islets of anglerfish (Lophius americanus) channel catfish (Ictalurus punctata) by means unlabeled antibody-peroxidase-antiperoxidase immunocytochemical method. Both species showed a similar ratio positive cells 9:6:4 (insulin:somatostatin:glucagon), but interrelations three cell types differed between species. The large number somatostatin-positive may be indicative an important role for this hormone teleost physiology. appear to good source tissue further work on somatostatin.
