Abstract


Used animales were male albino-rats, (130~150 Grams body weight). They were fed by the definite condition and divided into 2 groups. one group was exposured to the direct sunlight for an hour and the other group was stayed in the dark room for an. hour. and in the caurse of time passing, each of them were investigated to the appearances of the tissue mast cells of skin and every organ of the rats.
The results as follows:
1. In the group which exposured to the direct sunlight for an hour the number of the mast cells of the skin and every organ was gradually decreased in the caurse of time passing and it reached it´s lowest number at 12 hours after taking sunlight and then the number of mast cells was gradually recovered and increased it´s number and. one week later the number of mast cells was reached at it´s normal condition.
2. In the group which stayed in the dark room for an hour the number of the mast cells of the skin and every organ was gradually increased and showed it´s highest number at 12 hours after staying in the darkroom and then the number of the mast cells were gradually decreased in the caurse of time passing and one week later it reached at it´s normal condition.
3. In the above two experimental studies, in the cases of the decreasing number of the tissue mast cells, the percentage of the normal type of mast cells showed the decreasing value, on the contrary the percentage of the diffuse type of tissue mast cells were increased.
In the cases of the increasing number of the tissue mast cells the percentage of the normal type of tissue mast cells were increased, but the percentage of the diffuse type of mast cells were decreased,
4. According to the above results the appearances of the number of mast cells of the skin and the every organ of the rats were showed the relative sharp definite changes individually by the sunlight and the darkness.
