[Oxygen consumption and RQ-values in rats anesthesized with urethane and pentobarbital during continuous infusion of noradrenaline with and without glucose load].

For demonstration of the calorigenic effects of catecholamines on narcotized rats, ethylurethane and pentobarbital proved to be equally suitable as narcotics. Under urethane, narcotized rats showed no disorders of either glucose resorption or glucose utilization. With excessive oral supply, glucose becomes the preferential substrate in the energy metabolism of these animals.
