Effect of beta adrenoceptor stimulants on melanophore Index in frogs
YP Srivastava, BP Jaju
The effect of beta-adrenoceptor agonists and antagonists was studied on melanophore index in hypophysectomized and pinealectomized frogs. Isoprenaline and salbutamol produced dose dependent increase in melanophore index.The effect was significantly blocked by propranolol and practolol. Thus the beta agonists increase melanophore index by a direct action on melanophores. However, in the present study it has not been possible to differentiate melanophore beta adrenoceptors into beta-one or beta-two.
