[The effect of splenectomy, produced chemically by means of ethylpalmitate, on the formation of heteroagglutinins in the rat].

The formation of heteroagglutinins against human O-erythrocytes was pursued in Wistar rats splenectomized "chemically" by means of intravenous injections of ethyl palmitite. Contrary to some data in literature the initial inhibition in the formation of antibodies was replaced by a significant titre increase ranging from the 8th to the 14th day following immunization. The tween 20 contained in the emulsion of ethyl palmitic did not influence the formation of heteroagglutinins. The examinations show that a possible use of palmitic ethyl for immunosuppression is questionable.
