- Abstract: The effects of intramuscular or intracerebroventricular injection of penta-gastrin(PG) on the action potential amplitude (APA) of the myocardial cells and the heart rate(HR) were studied. The results were as follows:1 ) Injection of 10?g/10?l of PG into one of the lateral ventricles of the ratfailed to produce any effect on APA or HR. When the dosage of PG was doubled(20?g/10?l), then HR could be slowed down significantly (P
