Studies on Gastro-intestinal Movement in High Temperture and Humidity Chapter I. The Passage Time of Food through Stomach and Intestines of the Young Rabbits under Hot and Humid Environment

Young rabbits were reared in the environment with the wet temperature ranging from 23 to 30°C and with the humidity of 80 to 90 per cent for 47 days, and then the passage time of food through their stomach and intestines was examined by roentgenologic method. The following results were obtained 1. Under hot and humid environment the prolongation of the pyloric passage was found in 3 of 6 cases. 2. Under these conditions the passage time of food through the stomach and intestines was remarkably prolonged as compared with of control animals.
