[Fibrinolysis, immune reactivity and the structure of the blood serum albumin in obstructive lung diseases combined with atherosclerosis].

Fibrinolytic system, immune reactivity and isoelectric focusing of serum albumin were examined in 94 patients exhibiting combination of obstructive lung disease (chronic obstructive bronchitis and bronchial asthma) with atherosclerosis. Plasminogen activator showed discrete activity, the discreteness being less in respiratory distress of the I degree but higher in the distress of the II and III degree. Relative number of E-RFC and monocytes expressing receptors to IgM and IgG Fc-fragment decreased. Percentage of EAC-RFC rose. Serum albumin fractions changed pH range due to modification of albumin molecules resultant from forming complexes with fibrinogen degradation products. Concentration of the latter under conditions of respiratory distress induced by obstructive lung diseases associated with atherosclerosis substantially exceeded the standard levels.
