[Evidence of urinary glomerular basement membrane (GBM) antigens excretion in 3 rodents (rat, mouse, and guinea-pig) (author's transl)].

Immunodiffusion technique, with rabbits antibodies against rat glomerular basement membrane (GBM), permits to evidence the presence of GBM antigens into normal urines of 3 rodents (rat, mouse, and guinea-pig). These results confirm the earlier works in human and rabbit urines and show the antigenic communauty existing between the 3 rodents GBM, since we can evidence antigens of 3 different mammals with the same antibody. The origin and the nature of this patterns and the signification of this presence into mammalian urines are discussed.

[Rapid and simultaneous screening and quantitation of antitetanus and anti-HBs antibodies using Laurell's method].

Every transfusion Center which must hunt out anti-tetanus and anti-HBs antibodies to obtain specific corresponding immunoglobulins, is submitted to rapidity, precision and low cost necessity. In order to satisfy these obligations, the authors describe a simple and rapid method, allowing use of the same serum, through a single stage, and simultaneously, screening and quantitation of anti-tetanus antibodies (according to Laurells' method) and of fractionation suitable anti-HBs antibodies (through electro immunodiffusion). Technical conditions exposed in this paper allow direct quantitation of anti-tetanus antibodies from 1 to 30-40 IU; dilutions can be made for upper titers. False negative reactions due to zone effect, as observed in EID and passive haemagglutination do not occur while using this method. Its routine use contributes to the increase of the percentage of fractionation suitable plasmas, without overloading the screening laboratory's tash.

[Excretion in rat urine of substances derived from the basal glomerular membrane].

We have prepared in rabbits antibodies against rat GBM, with GBM prepared from isolated glomeruli issued from rat renal cortex. It is shown with immunodiffusion technique the excretion of basement membrane-like fragments into the normal rat urine. This result confirms the earlier works studying the human and rabbit urines. The origin and the nature of this patterns, the signification of this presence into the mammalian urines are discussed.
