Melatonin modifies carbohydrate and lipid utilization in exercised rats, maintaining glycemia and reducing plasma and liver lactate and plasma β-hydroxybutrate. This study was undertaken to determine whether effects on fuel metabolism were related to changes in nitric oxide(NO) production or growth hormone(GH) secretion. Male Sprague-Dawley rats received melatonin i. p. at a dose of 0.5 mg/kg body weight 30 min before being exercised to exhaustion on a treadmill at a speed of 24 m/min and a 12% slope. Melatonin ameliorated the decrease in plasma glucose and the increase in plasma urea, free fatty acid, β-hydroxybutrate, and nitrite induced by exercise. Melatonin-treated exercised rats had significantly elevated liver glycogen content and hepatic tissue showed a lowered expression of both inducible and constitutive NO synthase(iNOS and cNOS). Administration of the NO inhibitor NG-nitro-L-arginine(L-NAME) to exercised rats caused a significant reduction in plasma nitrite, but liver glycogen and biochemical parameters in blood did not significantly differ from untreated exercised animals, indicating the absence of a direct association between melatonin effects on fuel metabolism and NO levels. Although results of treatment with pyridostigmine, a cholinergic agonist drug that stimulates GH release, partially differed from that of melatonin, modulation of GH secretion could play a role in the metabolic actions of the hormone because effects of melatonin on exercised rats were almost completely blocked by simultaneous administration of L-NAME.
