摘要：

The products of the plasma clot destruction by the low-frequency ultrasound (US) were analyzed using the combination of SDS gel-electrophoresis, gel filtration chromatography and scanning electron microscopy. It was found that US (27 kHz) did not cause activation of the plasmin system or covalent bonds cleavage in the fibrin molecules. At US intensities less than 21.6 W/cm2 there was extraction of blood serum proteins, which are located in the pores of the fibrin network. The increase in intensity of ultrasonic action resulted in protofibril dissociation, which was accompanied by further release into the solution of the blood serum proteins, located inside fibrin fibers. After US cavitation protein extracted from the plasma clot underwent aggregation. Interaction between free protofibrils resulted in formation of insoluble fibrin particles. © Pleiades Publishing, Ltd. 2009.
