Effects of sinoaortic denervation on glucose utilization in the subfornical organ and pituitary neural lobe during administration of angiotensin II.
Angiotensin II infused intravenously into sinoaortic-denervated rats induced drinking and increased glucose utilization in the subfornical organ and pituitary neural lobe in amounts not different from those observed in sham-operated animals. We suggest that inputs from baroreceptors have a negligible influence on glucose metabolism in the subfornical organ during infusion of angiotensin II.
