Effects of Isoproterenol
نویسندگان
چکیده
Isoproterenol produced an increase in pulmonary blood volume and pulmonary blood flow without a significant change in pulmonary vascular pressures in 14 patients with obstructive lung disease, six of whom had cor pulmonale. These findings are consistent with a vasodilating effect on the pulmonary vasculature. Evidence is presented that muscular pulmonary arteries constricted by hypoxia were affected by the drug. There is little to suggest that the compliance of the elastic arteries was altered by isoproterenol.

Effects of histidine and vitamin C on isoproterenol-induced acute myocardial infarction in rats
In the present study, we investigated the effects of histidine and vitamin C (alone or in combination) treatments against isoproterenol (a β-adrenergic receptor agonist)-induced acute myocardial infarction in rats. We used propranolol (a β-adrenergic receptor blocker) to compare the results. Rats were given intraperitoneal injections of histidine (40 mg kg-1) and vitamin C (40 mg kg<...
