Abstract

|
|
Previous studies on the effect of the visible lights on the organism have shown the possible influences on the nervous system.
It was reported that the illumination of blue beam increased the sympathetic tone and thst of red beam increased the parasympathetic tone. The pharmacological actions of the sympathomimetics were also known to be altered by various visible lights. But their modes and mechanisms of actions on the nervous system have not been clarified and is obscure.
To elucidate the precise mechanism of action of the visible lights on the nervous system, present study was made to observe the survival time of the mole living in the dark environment, under the illumination of the various visible lights and influences of several drugs.
The results are summerized as follows:
1. The illumination of the natural sun light caused the survival time of the mole to be shortened and visible monochromatic beams (red, blue and green) even more markedly shortened the survival time.
No significant difference was noted depending on the wave length of the chromatic beam.
2. The shortened survival time caused by the visible monochromatic lights was prolonged by strychnine but not affected by morphine.
3, The survival time under the illumination of the visible monochromatic lights was prolonged by acetylcholine and physostigmine.
4. The shortened survival time under the illumination of the monochromatic visible lights was not affected by adrenaline but prolonged by priscoline.
It is suggested that the shortened survival time of the mole by the illumination of the visible lights can be prolonged by the stimulation of central and parasympathetic nervous system and blocking of the sympathetic nervous system.
