Experiment V. Effect of NE on N-acetylserotonin (a) and melatonin (b) release from the ovine pineal explants treated with transcription and translation inhibitors. The ovine pineal glands ( ) were divided into three explants, which were randomly assigned to the experimental groups. The explants were incubated in the medium containing group I, 0.5% DMSO from 301 min to 360 min and 10 μM NE + 0.5% DMSO from 361 min to 720 min of the experiment; group II, 10 μM ACT D from 301 min to 360 min and 10 μM NE + 10 μM ACT D from 361 min to 720 min of the experiment; and group III, 100 μM CLX from 301 min to 360 min and 10 μM NE + 100 μM CLX from 361 min to 720 min of the experiment. The data presented are means. The values significantly different ( ) between groups were signed with different letters. Black line is the level of NE in the culture medium. Blue bar is period of incubation in the medium with inhibitors; red bar is period of incubation in the medium with NE.
