　RELAXATION WITH PHOSPHOENOLPYRUVATE
　Rabbit psoas fibers kept initially at 0℃ in 50％ glycerol for two days and extracted further in 20％ glycerol at 20℃ for 4〜8 hours, develop maximal isometric tension on addition of 4 mM adenosinetriphosphate（ATP），and no appreciable spontaneous relaxation follows．According to recent work from this laboratory（1, 2），however, immediate relaxation of these fibers can be obtained if mM phosphoenolpyruvate（PEP）is added．
