title: Production of myocardial lesions in a graded fashion by noninvasive technique in albino rats.
abstract: Systematic study of producing graded lesions of myocardium with the use of Isoproterenol (IPT) reveals that mild to severe degree of infarction can be induced by administering the compound for one to four consecutive days in the dose of 85 mg/kg body weight in rats. These findings differ slightly from those of Rona et al. where they have not attempted to produce the lesions in a graded fashion. The experimental period can be reduced to two days by using high dose (170 mg/kg), but such procedure increases significantly the mortality in these animals and lesions are not produced in graded fashion.
