[Effect of middle molecular weight peptides, isolated from blood of intact dogs and those with burns, on proteolysis in mouse tissue].

The median molecular-weight peptides (MMP), detected in blood of patients with burns and in that of experimental animals with burns, were shown to affect various systems in vivo. The MMP from the blood of intact dogs and of the animals with burns exhibited the modifying effect on proteolysis within acid and neutral pH ranges in liver and brain tissues of mouse. The MMP appears to be involved in the regulation of proteolysis both in normal state and in burns.
