Abstract/OtherAbstract:
The purpose of this study was to determine the viability of the hamster pineal gland in organ culture and to test the effect of norepinephrine (NE) on [3H]serotonin derivatives. In this study, elevated levels of melatonin (7-fold, p less than .05), 5- hydroxytrytophol (5-fold, p less than .001), 5-methoxytryptophol (1.78-fold, p less than .05), and depressed levels of 5-hydroxyindoleacetic acid (3.8-fold, p less than .02) and methoxyindoleacetic acid (1.78-fold, p less than .05) were detected in the glands following the addition of NE to the medium. In a separate experiment, melatonin concentration in the media was also periodically measured by radioimmunoassay to determine the viability of the organ culture over a four-day period. The melatonin level on day 2 (2321 +/- 106 pg/gland) was significantly higher (p less than 0.01) than on day 3 (1542 +/- 86 pg/gland) or day 4 (805 +/- 39 pg/gland). The results of these experiments verify the viability of the hamster pineal organ culture and show that the gland responds to NE in vitro.
