A NOTE ON NITROGEN RETENTION FOLLOWING REPEATED INJECTIONS OF NEPHROTOXIC AGENTS.
It is possible by means of repeated injections of uranium nitrate to produce in the cat a subacute or chronic nephritis which can progress to a fatal termination and show in its course increasing accumulation of non-protein nitrogen in the blood. This nephritis differs only slightly from the spontaneous chronic nephritis of the species. Repeated doses of diphtheria toxin produce a subacute form of nephritis with only temporary or slight retention, but nevertheless anatomically a well defined nephritis. The spontaneous nephritis studied resembles more closely that produced by uranium nitrate than that produced by diphtheria toxin both histologically and from the standpoint of blood analysis.
