Abstract:
The effect of plasma middle molecule substances (MMS) on the Ca2+-ATPase activity in human erythrocyte membranes was studied. The results showed that the Ca2+-ATPase activity was significantly inhibited when the membrane preparation was incubated with MMS at 37℃. The longer the period of time for incubation, the lower the Ca2+-ATPase activity. The activity of Ca2+-ATPase could be significantly inhibited by plasma MMS of both normal person and burn patient. The inhibitory rate (%) of Ca2+-ATPase activity was elevated markedly when MMS concentration was increased (P
