16, 50 Hz exposure to isolated pineal glands of Djungarian hamsters and analysis of melatonin level |
Details |
|
Isolated pineal glands of Djungarian hamsters (Phodopus sungorus) were exposed to magnetic fields (16.67 or 50 Hz at 86 microTesla)for 8 hr. In each experiment, 12 exposed and 12 sham-exposed pineal glands were placed individually in glass chambers which were surrounded by identical coils. After 3.25 hours of adaptation, melatonin production was stimulated by isoproterenol (10-7 M) for 30 min. Eluted fractions were collected, and melatonin concentrations were measured by radioimmunoassay. Statistical analyses for each frequency showed significant suppressive effects at 162/3 Hz (P<0.01) and 50 Hz (P<0.001). It is concluded that the suppressive effects of magnetic fields on the synthesis of melatonin are a result of primary mechanisms at the level of the pineal gland. |
