Abstract
The formation of a fibrin film at the sites of cuts and wounds is a complex biochemical process that involves fibrinogen and thrombin as the main components, as well as other enzymes and proteins. Dynamic surface properties of adsorption films obtained from the solution, which contains factors VIII, XIIIa, von Willebrand factor and fibronectin, differ from the fibrinogen adsorption films and fibrin films obtained from a solution containing only fibrinogen and thrombin. Their dynamic surface elasticities exceed the corresponding values for fibrinogen (80 and 55 mN/m, respectively); however, they appear to be lower than value for fibrin prepared from pure components (115 mN/m). The surface pressures achieved for the adsorption films obtained from hemostatic glue (27 mN/m) exceed those for both aforementioned systems (14 mN/m). As follows from the Brewster angle microscopy and scanning electron microscopy data, significant changes in the morphology of the resulting films are responsible for the observed effect.
期刊介绍：
Colloid Journal (Kolloidnyi Zhurnal) is the only journal in Russia that publishes the results of research in the area of chemical science dealing with the disperse state of matter and surface phenomena in disperse systems. The journal covers experimental and theoretical works on a great variety of colloid and surface phenomena: the structure and properties of interfaces; adsorption phenomena and structure of adsorption layers of surfactants; capillary phenomena; wetting films; wetting and spreading; and detergency. The formation of colloid systems, their molecular-kinetic and optical properties, surface forces, interaction of colloidal particles, stabilization, and criteria of stability loss of different disperse systems (lyosols and aerosols, suspensions, emulsions, foams, and micellar systems) are also topics of the journal. Colloid Journal also includes the phenomena of electro- and diffusiophoresis, electro- and thermoosmosis, and capillary and reverse osmosis, i.e., phenomena dealing with the existence of diffusion layers of molecules and ions in the vicinity of the interface.
