We have investigated the influence of cortisol on the beta-adrenoreceptor population of rainbow trout [Oncorhynchus mykiss (Walbaum)] erythrocytes and determined what impact it has on the adrenergic responsiveness of erythrocytes in vitro to exogenous catecholamines. To do so, the erythrocyte beta-adrenoreceptors were characterized in fish with chronically elevated plasma cortisol levels (118 +...

Am J Physiol Regulatory Integrative Comp Physiol 278: R956–R963, 2000.— The rate of hepatic glucose production (Ra glucose) of rainbow trout (Oncorhynchus mykiss) was measured in vivo by continuous infusion of [6-3H]glucose and in vitro on isola...
