Adrenergic Activation of Melatonin Secretion in Ovine Pineal Explants in Short-Term Superfusion Culture Occurs via Protein Synthesis Independent and Dependent Phenomena

Experiment I. Effect of different concentrations of NE on melatonin secretion from the ovine pineal explants. The ovine pineal glands ( ) were divided into four explants, which were randomly assigned to the control and experimental groups. The explants were incubated between 361 and 720 min of the experiment in the medium containing group I, 0.1 μM NE; group II, 1 μM NE; and group III, 10 μM NE. The explants from group IV (control) were not treated with NE. The mean melatonin secretion between 301 min and 360 min of the experiment was taken as 100%. The data presented are means. The values significantly different between groups were signed with different letters. Red bar is period of incubation in the medium with NE.
