Jacqueline M. Davis,Casey T. DeRoo,Melville P. Ulmerexcitation-contraction (E-C) coupling in skeletal muscle (Weber, Herz & Reiss, 1964; Portzehl, Caldwell & Rüegg, 1964; J?bsis & O’Connor, 1966; Hellam & Podolsky, 1969). These changes in intracellular calcium can now be monitored during the contraction of a single muscle fibre by a photometric metho

Bianca Salmaso,Alberto Moretti,Jessica Gaskiness of hormone release may be no less critical. Thus the synaptic release of acetylcholine and noradrenaline is calcium dependent (Harvey & MacIntosh, 1940; del Castillo & Stark, 1952; Hukovi? & Muscholl, 1962; Kirpekar & Misu, 1967); but so, too, is the release of many hormones (Table 1).

M. W. Bautz,Andrew D. Holland,D. H. Lumbolleagues have published since 1961 (Douglas, 1968). However, three major questions concerning the calcium-dependent secretion of catecholamines remain unanswered. These are, first, how is calcium entry into chromaffin cells regulated; second, what is the nature of the process activated by calcium;

J. W. den Herder,Marco Feroci,Norbert Meidingernge or intracellular distribution of many ions including calcium. In the case of the steroid hormones, cortisol and vitamin D, there is considerable . evidence that prior treatment of animals with either of these hormones leads to changes in transcellular transport of calcium (Schacter, 1970; Harris

Sebastian Dieboldich selectively bind this ion. One of the best known compounds of this type is ethylene-diamine-tetra-acetic acid (EDTA) which binds calcium about 100 times more effectively than it binds magnesium. In recent years, however, EDTA has been superseded in many studies involving calcium by ethylene-glyc
