Abstract: | The effect of high hydrostatic pressure (100-1400 at) on frog skeletal muscle was studied. Superthreshold pressures (above 600 at) accompanied by muscle contracture results in the intensification of sorption of both basic (neutral red) and acid (phenol red) dyes, and in the growth of the number of oxidated forms of respiratory metabolic components--flavoproteins and pyridine nucleotides under study. Subthreshold pressures reduce the tinctorial ability of muscles and decrease oxidative processes caused by the maintenance of muscle in small volume of the Ringer solution. |
