[Effect of staphylococcal peptidoglycan on the activity of Ca2+-ATP-ase from the sarcoplasmic reticulum in the early stages of ionizing radiation effect].

It is established that peptidoglycan of Staphylococcus aureus possess superficial activity and can render influence on the functional activity of biomembranes. It tends to increase Ca(2+)-ATP-ase activity in the sarcoplasmic reticulum membranes, but no changes have been observed in case of the enzyme solubilization. The effect of peptidoglycan was more expressed, if it was used in the early period of acute radiation injury (1 and 24 h) in a dose of 0.21 Cl/kg for samples with irradiation-induced decrease of Ca(2+)-ATP-ase activity.
