Abstract

Inhibitors, of trypsin, plasmin, alpha-chymotrypsin and granulocyte elastase were demonstrated in salivary gland extracts from two species of leeches. Haementeria ghilianii and Haementeria officinalis. Preliminary fractionation of salivary gland extracts from Haementeria ghilianii allowed separation of protease inhibitors from hementin a fibrinogenolytic blood anticoagulant. It was found that the anticoagulant activity resided only in hementin-containing fractions and did not parallel protease inhibitory activity.

Trypsin, plasmin, alpha-chymotrypsin and granulocyte elastase inhibitors demonstrated in Haementeria ghilianii and H.

Por qué esto importa para la hirudoterapia

This study demonstrated the presence of trypsin, plasmin, alpha-chymotrypsin, and granulocyte elastase inhibitors in salivary gland extracts from two Haementeria leech species (H. ghilianii and H. officinalis), and separated these protease inhibitors from hementin, a fibrinogenolytic anticoagulant. It is directly relevant to ASH's domain because it characterizes additional bioactive components of the leech secretome beyond the well-known anticoagulants, potentially informing understanding of how leech saliva modulates wound healing and inflammation. However, the work is preclinical biochemical characterization using salivary gland extracts only; there are no in-vivo, clinical, or hirudotherapy data, and no functional therapeutic claims are made.
