Beta-adrenoceptor stimulants and mesovarian leiomyomas in the rat

The experiment reported here shows that mesovarian leiomyomas may be induced in rats by the administration of 2 chemically distinct adrenergic stimulants, salbutamol or terbutaline. That the induction of these benign tumours is a function of adrenergic stimulation is shown by the fact that the concurrent administration of the adrenergic blocker propranolol prevented their development.
