Abstract
The new sulphonylurea CS 476 does not potentiate the effect of insulin on plasma glucose levels in diabetic dogs in which an oral glucose load does not cause insulin release. In normal dogs propranolol 0.3 mg/kg intravenously inhibites the insulin release and the hypoglycaemia due to CS 476 suggesting involvement of beta-adrenergic receptors in its action on the pancreas. Pretreatment of dogs with phentolamine leads to an augmentation of the insulin response to CS 476.
