The effect of glucagon on the glycosaminoglycan content of canine arteries.
Hypophysectomized young beagles were treated for 21 days with pharmacological doses of glucagon, administered intramuscularly in two daily injections of 0.5 mg each. Hyaluronic acid, heparan, dermatan and isomeric chondroitin sulphates were determined in aorta, carotid, iliac, renal, mesenteric and coronary arteries. In comparison with age-matched hypophysectomized controls, glucagon-treated dogs showed a reduction in the heparan sulphate concentration in their carotid arteries and thoracic aorta. These results indicate that glucagon has a very limited effect on arterial glycosaminoglycan content.
