[Agammaglobulinemia and secretory IgA (author's transl)].

After serum IgA has been intravenously administered, it appears immediately in secretions, sputum, and urine. At about the same time, a mechanism is employed which leads to the concentration of IgA in the sputum. In urine, 7sIgA and SC were separately eliminated; a linkage with 11sIgA did not occur. Similar relationships are probably present in the sputum, but exact proof could not be provided. By administrating immunoglobulin concentrates which contain IgA in 7s-serum form, the IgA concentration in external secretions can be raised; replacing the physiological 11s-IgA however, is not possible. The extent to which 7sIgA can take over the function of 11sIgA in these secretions has not yet been clarified. In this connection, the use of local 11sIgA inhalation therapy rather than ultrasound atomazation seems to be well founded theoretically and also promising. Whether such therapy can be carried out practically and is successful remains to be seen.

[Determination of L-cystine aminopeptidase (serum oxytocinase, EC 3.4.1.2) during normal pregnancy].

It is given a method to the determination of cystine aminopeptidase activity in the serum in pregnancies. A time of few minutes is necessary for one determination. The determination is performed with a spectralphotometer or with the Reaction Rate Analyzer (LKB 8600) in using the chromogen substance 1-cystine-bis p-nitroanilide. This substance is solved in dimethylformamide. The normaly range of the 8th to the 41 th week of pregnancy is determinated in a number of 453. In twins the values were higher. The cystine aminopeptidase is nearly specifically in pregnancies and is produced in the plazenta. It is a statement of cellulary activity in the plazenta.

[Head endoprostheses in femoral neck fractures].

By clinical, radiographic and scintigraphic means we attempted to examine, whether the implantation of a simple head-endoprosthesis after fractures of the femoral neck still has to be considered as an appropriate operating method or whether on principle, primary endoprosthesis should be used. The results prove that in suitable cases and with correct technique the head-endoprosthesis still has justification, especially as the "protrusio acetabuli", known only as complication of pure head-endoprosthesis, is mostly avoidable. Reference to the choice of cases, operating conditions and appropriate methods of examination are given.
