| 内容記述 | To establish the intracellular Ca translocation during the contraction-relaxation cycle in the swimbladder muscle (SBM) of a scorpionfish (Sebastiscus marmoratus) , a cytochemical study using a pyroantimonate (PA) method was performed. In the resting state, PA precipitates cytochemically indicating the presence of Ca were found only in the terminal cisternae (TC) of the sarcoplasmic reticulum (SR). On the other hand, during caffeine-induced contractures, the number of PA precipitates remarkably decreased in the TC, and they appeared newly in the myoplasm, distributed diffusely around myofibrils. During the recovery period, after the onset of relaxation from the caffeine-induced contracture, PA precipitates disappeared in the myoplasm, and were newly found in fenestrated collars (FC) and longitudinal tubules (LT) of the SR. Later, in the fully relaxed fibers after tetanus, PA precipitates were again found mainly at the TC. These results supported our previous view that Ca2+ released from the TC during contraction is first taken up mainly by the FC and the LT during the relaxation, and then gradually returns to the TC by passing through the SR lumen. | |||||
