[Interrelations of organ systems].

The main features of interrelations between different organ systems are described and their possible role in therapeutic aims discussed. In the question on the connection of immunoallergic phenomena and vegetative nervous system the authors' standpoint on their mutual interrelation is stressed. The most important characters of the immunoallergic organ system are studied and its correlations with the female hormonal factors interpreted; further therapeutic trials in this aspect seem to be justified.

[Classification of immunodeficiency].

The immunodeficiency, at present an important complex of research, can be classified in 4 main groups. Primary forms can be separated from secondary ones, a third group of interactional type from a fourth one of compensatory character. We suggest a new classification based on a common point of view, which avoids terms as "common variable immunodeficiency" and allows corrections by the results of further research.
