title: [Effect of vanadium compounds on the enzymic activity in sarcolemma of developing muscles].
abstract: Sodium metavanadate (10(-4)-10(-6) M) stimulates the activity of adenylate cyclase and decreases the activity of Na+, K+-ATRase and 5'-nucleotidase in the sarcolemma fraction of chicken skeletal muscles at the embryonal and postembryonal developmental stages. Under conditions of a combined action of vanadate and guanylic nucleotides on the adenylate cyclase activity their effects are found to be potentiated. Epinephrine in vitro removes an inhibitory influence of vanadate on Na+, K+-ATPase from the third week of twe embryonal period. The restoring effect of epinephrine is blocked by propranol--a beta-adrenoblocker.
