Plasma corticosterone levels in the male iguanid lizard Sceloporus cyanogenys under various physiological conditions

Variations in peripheral plasma corticosterone levels in male iguanid lizards, Sceloporus cyanogenys, were investigated under varying physiological conditions. Control baseline levels of the steroid in plasma were significantly decreased by hypophysectomy, adrenalectomy, hypothalamic lesions, and cyanoketone, an inhibitor of Δ5-3β hydroxysteroid dehydrogenase. Levels were increased following treatment with mammalian ACTH in both intact and hypophysectomized […]
