Abstract
The influence of metabolic substrates (glucose, fructose, lactate, pyruvate) on the spontaneous motility of uterine strips isolated from estrus or spayed rats was explored. The effects of substrate omission on tissue glycogen and triglycerides in both hormonal conditions were also studied. The results indicate an important role of glycolysis for rat uterine motility. It would appear also that the better contractile performance of strips from ovariectomized animals might be related to their capacity to metabolize readily triglyceride energy stores.
