Abstract
The convulsion of the rabbit was induced by an injection of convulsion's toxin, and the intestinal movements were observed through the abdominal window. The results were as follows.
1. The intestinal movements in vivo were completely stopped at the time when the convulsion occurred, and the blood vessels of the intestine schowed severe anemia.
2. In the case of the splanchnicectomized rabbit the intestinal movement was promoted after the convulsion, but there was no promotion of intestinal movement in the vagotomized one.
3. There was no significant difference in the dosage which induced the convulsion both in the normal rabbit and the autonomic neurectomized one.
4. It seems that the intestinal movement is controlled by the autonomic nerves and that the variation of the intestinal circulation has a great effect upon it.
