摘要：

When fibers of a smooth invertebrate muscle (Anterior byssus retractor muscle of Mytilus edulis) were perfused with a solution of calcium, oxalate and ATP, electron opaque calcium oxalate was accumulated in vesicles subjacent to the sarcolemn. Salyrgan, an inhibitor of the extra ATPase, which is related to calcium uptake, blocks the calcium oxalate storage. This suggests a function of these vesicles similar to that of sarcoplasmic reticulum in vertebrate striated muscle, which consists in regulating the contraction relaxation cycle by varying the calcium concentration in the sarcoplasm. © 1969 Springer-Verlag.
