Effect of stress stimuli on glycogen level in the rat uterus

Effect of prolonged exercise, acute cold exposure, and 24-h fasting on the glycogen level in the uterus of rats spayed and than treated with peanut oil or estradiol was investigated. It has been found that exercise increases significantly though transitorily the glycogen level in the uterus of the oil-treated group. Cold exposure resulted in significant reduction of the uterine glycogen level only in the oil-treated group. Fasting did not change the glycogen level in the uterus in the both groups. Five hours of swimming and fasting decreased significantly the blood glucose level.
