Hypoglycemia Per Se Stimulates Sympathetic Neural as Well as Adrenomedullary Activity, but, Unlike the Adrenomedullary Response, the Forearm Sympathetic Neural Resposne Is Not Reduced After Recent Hypoglycemia

摘要

We tested the hypotheses that 1) hypoglycemia per se stimulates the sympathetic neural as well as the adrenomedullary component of the sympathochromaf- fin system, and 2) sympathetic neural responses to hypo- glycemia, like adrenomedullary responses, are reduced after recent hypoglycemia. To tis end, we studied 10 healthy young adults on 2 consecutive days on two sep- arate occasions, on one occasion with euglycemia (5.0 mmol/) and on the other occasion with hypoglycemia (2.8 mmol/l) from 1000 to 1200 and 1400 to 1600 on day 1 of each occasion.
