Abstract
The generalized Shwartzman reaction, or Shwartzman-like conditions, were induced in a variety of experimental mammalian species by systemic injections of disintegrated cells of Gram negative bacteria, live Salmonella cholerae-suis or Liquoid. A comparative study of the renal lesions showed that the initial step in the development of bilateral cortical necrosis is stagnation and disintegration of red cells in glomerular capillaries. The glomerular “microthrombi” consist mainly of erythrocytic debris, which frequently has staining properties akin to those of fibrin; even wide-spread glomerular “thrombosis” is not accompanied by obvious destruction of renal parenchyma. A second step is necrotic mural lesions in afferent arteries, with ensuing thrombosis. These vascular lesions lead to the formation of individual infarcts which fuse to form total bilateral cortical necrosis in fulminant cases of the generalized Shwartzman reaction.
