| 内容記述 | The effect of caffeine on the osmotically treated sartorius muscle of the bullfrog was studied. Muscles soaked in distilled water rapidly gained up to 190% of their initial weight and then reached a stationary state. Electrical stimulation of the hypotonically treated muscles at 40 Hz suppressed the weight increase, while stimulation at 10 or 20 Hz did not. Electrical stimulation of the muscle soaked in Ringer's solution also resulted in a weight gain up to 100%. Caffeine solutions of 10,15 and 20 mM induced weight increase, while a 40 mM caffeine solution resulted in a small weight loss. These results indicate that water movement through the muscle cell membrane is influenced by the excitation and tensions produced by caffeine contracture. | |||||||||
