Effect of cardiac sympathectomy, reserpine, and environmental temperatures on the catecholamine levels in the chicken heart

Abstract

Cardiac catecholamine levels were spectrofluorometrically determined in adult male chickens following two treatments: (1) denervation of the cardioaccelerator nerves or (2) reserpine administration after acclimatization of the birds to low, intermediate, or high ambient temperatures. Marked depletion of cardiac catecholamines (80 to 90%) was found 2 weeks after denervation and 24 h after injection of reserpine. Acclimatization did not alter the response to reserpine.

“…Citrus peel extract, which represents roughly one half of the fruit mass, is a rich source of bioactive compounds including natural antioxidants such as phenolic acids and flavonoids 13 . The most investigations on Citrus reticulate varieties were deal with their essential oil analysis but it had been reported, Hesperidin is the most important flavonoid which found in Citrus reticulate peel extract has a wide range of pharmacological properties 14 .…”

“…/G/m'* ly norepinephrine which is bound normally to sympathetic nerve terminals (12). The nature of the binding of the 5HT in the avian heart is not known, but apparently it is a loose one, because perfusion of the isolated heart washes out all 5HT in a short time, but not tightly bound norepinephrine (9, 10).…”
