[Intolerance to cow's milk].

The authors report results of allergological history, of passive haemagglutination reaction, lymphocytes blast transformation and leucocytes migration inhibition tests in 100 patients suffering from affections involving the gastro-intestinal tract. Control investigations were carried out in 20 practically healthy individuals. From these results the authors conclude that the data of the allergological history and clinical symptoms of the cow milk intolerance are determined, above all, by the immuno-allergic mechanisms, this being confirmed by the results of the "in vitro" methods characterizing the humoral and cellular types of the immunological reactivity.
