title: The sympathetic neuro-melanophore transmission in a fresh-water Indian major carp, Labeo rohita (Ham.).
abstract: Adrenaline was effective in aggregating the melanosomes both in innervated as well as denervated melanophores. Isotonic KCl could induce pigment aggregation only in innervated melanophores. Adrenaline- and K+-induced pigment aggregation response in these melanophores was blocked by phentolamine: propranolol failed to do so. It is suggested that the chromatic nerves in the fish, Labeo rohita are adrenergic and via post-synaptic alpha-adrenoceptors, control the melanosome aggregation.
