[Mechanism of potentiation of contraction in glycerol-treated muscles].
The glycerol was shown to lead to a considerable though transient increase in the contractile amplitude of the m. sartorius. Prolonged incubation of the muscle in the Ringer and Ca-free solutions in presence of glycerol led to a decrease in the response following potentiation. The potentiation due to glycerol seems to be caused by Ca2+ release which, in its turn, is due to the glycerol effect on membranes of SR and T-systems.
