ABSTRACT
Adrenergic and cholinergic receptors have been studied in isolated skin melanophores of a catfish Clarias batrachus. Catecholamines induced a strong aggregatory effect on the melanophores. Melanosome aggregation induced by adrenaline and noradrenaline was partially blocked by alpha adrenergic receptor blockers and a beta receptor blocker. Cholinomimetic drugs aroused a significant dispersion of melanophroes. Atropine effectively blocked the dispersal, responses of melanophores to acetylcholine and carbachol, while, hexamethonium blocked the nocotine induced dispersal responses of the melanophores.
