[Experimental study of azathioprine in nephrotoxic nephritis in rats].

In tests conducted with 165 mongrel sexually mature and immature rats it is shown that azathioprine used in nephrotoxic nephritic improves the general condition, reduces the edema of subcutaneous cellular tissues, as well as the intensity of proteinuria and helps retaining its selective type, lessens the degree of hypo- and dpsproteinemia and, especially, of hyper-beta-lipoproteinemia; in the kidneys the pathomorphological changes characteristic of nephritis become less marked. Azathioprine does not influence the process of acido-and ammoniogeness in the tubuloar system of the nephron, nor does it modify diuresis. The effect of azathioprine is most spectacular in the acive phase of developing nephritis. In rattlings with nephritis theaction af azathioprine in regard to a number of factors (proteins, beta-lipoproteids, gamma-globulins of the blood) is somewhat stronger than in the sexually mature rats.
