The effects of various horse serum fractions in producing cardiovascular and renal lesions in rabbits

The induction of rheumatic-like cardiac lesions in rabbits by repeated focal infections with group A streptococci; comparison with the cardiac lesions of serum disease

Cardiac lesions like those characteristic of rheumatic fever in man have been induced in a small portion of rabbits that were subjected to successive focal infections with group A streptococci of several serological types. Fresh myocardial interstitial granulomata so induced bear striking resemblance to Aschoff bodies, the histologic hallmarks of human active rheumatic fever; and the fresh and healed lesions found in the cardiac valves, endocardia, epicardia, blood vessels, and aortae of some of these rabbits are homologous with those characteristic of rheumatic fever in man. These experimental myocardial and vascular lesions and those of human rheumatic fever differ in several important respects from the lesions of experimental and human serum disease.

Experimental globulin glomerulonephritis in rabbits; morphological and functional changes

Diffuse glomerulonephritis was induced in unilaterally nephrectomized albino rabbits by giving them two massive intravenous injections of purified bovine serum gamma globulin. Morphologically, these renal lesions were similar to those of human acute and subacute glomenilonephritis. Globulin nephritis in rabbits also closely resembles experimental nephritis induced by injection of other foreign proteins. The course of this experimental disease was characterized by abrupt onset of proteinuria, hematuria, elevation of serum globulin, and reduction of albumin. Uremia developed in some animals. The manifestations of nephritis during life coincided with the development of demonstrable antibodies to the injected globulin. In view of the similarities between experimental globulin nephritis in rabbits and human nephritis, together with common features with other experimental nephritis, it is suggested that all may have a common pathogenetic mechanism. It is concluded that quantitative antibody response may be of greater importance in the pathogenesis of nephritis than antigen specificity.
