[Various features of peroxidase in human saliva].

Optimal conditions are determined for isolation and purification of peroxidase (EC 1.11.1.

[Activity of the proteolytic system in patients with breast cancer].

Proteinase inhibitor activity in patients with stage IIb, III and IV breast cancer was shown to be higher than in healthy donors and cases with stage I-IIa disease. The proteinase activity/inhibitor activity ratio in breast carcinoma tissue appeared higher than in benign tumors and normal tissue. Tumor proteinase activity was in reverse correlation with degree of cell differentiation.

[Effect of trypsin and kallikrein (andecalin) on the activity of proteolytic enzymes and their inhibitors in acute experimental pancreatitis].

Intramuscular administration of trypsin and kallikrein (andecaline) into rats contributed to more favourable development of acute traumatic pancreatitis. Trypsin and andecaline prevented the activation of proteinases in blood serum and pancreas and promoted an increase in content of trypsin inhibitor in blood serum. The proteinases efficiency appears to depend on elevation of general resistance of the organism to the trauma.
