Recently it is reported that in the muscular contraction the contractile protein complex actomyosin (AM) and adenosine tri-phosphate (ATP) as a source of high energy play important role 1,2,3,5). However, most of these investigations are restricted to the skelet muscle and there are only a few reports on the involuntary muscle 7,8,9,10). As for the onset of labour or premature interruption of pregnancy there have been offered not a few hypotheses, which cannot, however, explain the complicated mechanism or cause either. In the present paper the difficult problem of the uterine muscular contraction was tried to approach from the activity of actomyosin ATPase in the different phases of gestation of the rat.

ENZYMOLOGICAL STUDIES ON THE CONTRACTION OF THE PREGNANT UTERINE MUSCULATURE

-ON THE INFLUENCES OF ANORGANIC SUBSTANCES UPON ACTOMYSIN ADENOSIN-TRIPHOSPHATASE (AM-ATPase)-

In the previous report the authors prepared a kind of raw AM-ATPase out of uterine muscle of the rat during pregnancy and parturition and confirmed a remarkable increase of AM-ATPase activity in the latter l). The present paper describes the influences of various anorganic substances on the activity of the raw enzyme prepared from pregnant uterus of the rat.

ENZYMOLOGICAL STUDIES ON THE CONTRACTION OF THE PREGNANT UTERINE MUSCULATURE

-ON THE INFLUENCE OF PLACENTAL EXTRACT ON ACTOMYOSIN-ATPase-

With purpose of investigating constraction of the pregnant uterus from enzymological stand point the authors l,2) confirmed that the activity of actomyosin ATPase prepared from rat’s pregnant uterus was significantly elevated during contraction, and that the enzyme was activated by Mg and Ca ions and inhibited by Fe and Cu ions. In the present experiment the same enzyme activity was observed under influences of anorganic ions derivd from the placental tissue.

In the previous reports l,2) of the authors the influences of anorganic ions and placental substances of the rat and woman on actomyosin ATPase of the rat were investigated. As for the ions, Ca, Mg and Mn activated, and Fe and Cu inhibited the actomyosin ATPase of the rat’s pregnant uterus. In the present paper the actomyosin ATPase was prepared from the human pregnant uterus and examined under action of anorganic ions.
