THE EFFECTS OF GANGLIONIC AND ADRENERGIC BLOCKADE ON THE CIRCULATION OF THE YOUNG CHIMPANZEE

The role of the autonomic nervous system in circulatory control in young chimpanzees was evaluated through the use of selected autonomic blocking agents. Ganglionic blockade resulted in decreases in cardiac output, heart rate and arterial pressure. Beta adrenergic blockade resulted in similar decrea...

Zusammenfassung:	The role of the autonomic nervous system in circulatory control in young chimpanzees was evaluated through the use of selected autonomic blocking agents. Ganglionic blockade resulted in decreases in cardiac output, heart rate and arterial pressure. Beta adrenergic blockade resulted in similar decreases in cardiac output and heart rate, while arterial pressure was unchanged. Alpha adrenergic blockge caused a decrease in arterial pressure and peripheral resistance. Heart rate rose and cardiac output showed no consistent change following alpha adrenergic blockade. (Author)
