A scanning electron microscopic study of crescentic Masugi nephritis in the rabbit.
Crescentic glomerulonephritis was induced in the rabbit with two intravenous injections of goat nephrotoxic serum (NTS). Prominent proliferative glomerulonephritis, characterized by intracapillary as well as extracapillary emigration of monocytes and fibrin deposition, developed 7 days after the first injection. The changes rapidly progressed to crescent formation. In order to observe alterations of the glomerular basement membrane (GBM) related to crescent formation, unfixed, isolated glomeruli were treated with Triton X-100. The GBM thus denuded was shown to have a number of microperforations, which subsequently became much larger holes or fissures. It is suggested that monocytes and fibrin deposits may play a role in the induction of the GBM change.
