Summary A quantitative restriction of food intake for 7 days reduced the amplitude of spontaneous miniature endplate potentials by about 1/3 in rats aged 30 days but not in rats aged 110 days.I would like to thank Dr D. V. Roberts for encouragement and advice and the Medical Research Council and the Muscular Dystrophy Group of Great Britain for financial support. 相似文献

Summary A.T.P. has no influence upon the solubility of the myosins, but it hastens the dissociation of the myosin complexes inside of the myofibrils.The decrease in solubility of the myosins in stimulated muscles cannot be explained by a lack of A.T.P., for the addition of A.T.P. (0.3%) to the extract does not change the amount of myosin which goes into solution. 相似文献

3 experimentally distinct transverse relaxation components of the water in frog sciatic nerve are obtained by Carr-Purcell-Meiboom-Gill technique. The relative weights of these components: approximately 29%; approximately 50%; approximately 21% fit well with water compartments in this tissue as revealed by previous methods. 相似文献
