[Protein fractions and their enzyme activity in the rat myocardium in a Kosmos-936 biosatellite experiment].
The effect of artificial gravity on protein fractions and their enzyme activity in the myocardium of rats flown on board Cosmos-936 was studied. In weightless rats the content of sarcoplasmic proteins increased at R + O and that of T fraction proteins decreased at R + 25. In centrifuged rats such changes were not seen. In centrifuged rats the enzyme activity of sarcoplasmic proteins did not alter. In weightless rats ATPase activity of myosin decreased significantly, and in centrifuged rats it remained almost unchanged.
