[Quantitative fluorometric determination of gamma globulin and fibrin in the aortic wall of rabbits with experimental atherosclerosis].

By means of the fluometric method in 76 rabbits at definite stages of the development of experimental atherosclerosis in the aorta an increased amount of gamma-globulin and fibrin was established. An increase in the level of gamma-globulin was accompanied by fixation of beta1C-fraction of complement, which is characteristic of deposit of an immune complex. The most pronounced concentration of gamma-globulin was noted in areas of lysis and fragmentation of elastic fibres.
