Fluctuation of Blood Melatonin Concentrations With Age: Result of Changes in Pineal Melatonin Secretion, Body Growth, and Aging
Abstract
Melatonin in the systemic circulation of rats fluctuates with age, and the causes for such changes were investigated. Male rats (aged 7 days, 16 days, 18 days, 20 days, 30 days, 48 days, 60 days, and greater than 17 months) were adapted under a lighting regime of 12L:12D for at least 7 days. Pineals and blood samples from the trunk or confluens sinuum were collected in the dark period. Melatonin in tissues was extracted, identified, and …
