The function of secretory antibodies is to prevent or limit the entrance of pathogens into the internal milieu of the body. The mucosal immune system may be stimulated by orally applied immunomodulators. Oral immunization circumvents the stringent criteria for injectable vaccines and large populations can be immunized simultaneously. Oral immunization may improve the chances in eliminating severe respiratory diseases, venereal diseases and infectious diarrhoea. In this overview the results of 144 international publications are discussed critically.

There is no comprehensive theory for the various reasons for dyspnea. It is proposed to regard the disproportion between "input" and "output" as the common cause of the various forms. This disproportion may be located between psychological drive and neural response or between neural excitation and muscular response or between muscular activity and ventilatory effect. Thus insufficient perfusion of respiratory muscles--as in cardiac failure--may cause dyspnea. Arterial oxygen pressure as the criterion of sufficient ventilation is misleading in anemia and CO-poisoning, so that there is no dyspnea despite of insufficient O2-transport.

Simulated samples of sputa respectively negative sputa artificially contaminated with mycobacteria were sent to mycobacteriological laboratories in CSFR and the former GDR for the purpose of conducting an external quality control of the process employed in bacteriological examination. The average percentage of positive results corresponding with the reference material came to 75.7% in CSFR and 92.0% in former GDR. Methodological differences influencing the results of external laboratory control in both countries are discussed. Systematic external controls are recommended as an invaluable aid for improvement of the bacteriological demonstration of mycobacterial infections.

The premature rabbit neonate of the 27th day of gestation is a useful model for testing intratracheally applied surfactant preparations. Immediately after application of an effective surfactant the thorax lung compliance--as the decisive measure--rises significantly. We could exclude effects of the applied fluid per se. The most reliable result about the efficiency of a surfactant preparation is given by the cumulative dose response relationship. In a semilogarithmic system there is a linear relationship between the surfactant dose (25-200 mg phospholipids per kg b.w.) and the thorax-lung-compliance.

The aim of a one year study was to ascertain whether air pollution measured as NO2-concentration has an measurable influence on the health of infants in Switzerland. Measurements of NO2-concentration were carried out by means of passive collectors in ambient air, living room and at the child itself. The results of 1225 children printed to a significant coherence between respiratory symptoms per day and child and the NO2 load of ambient air as an guide pollutant. Even in consideration of other childish, familiar and environmental factors the coherence remains. Although no causal relation thereby proved this factor supports the observation of parents and physicians that children more often fall ill of respiratory diseases in polluted air being in accordance with similar investigations abroad.

755 patients were treated because of tuberculosis from 1984-1989. The treatment was standardized according to the recommendations. INH and RMP were used in over 95% as in the hospital as in the ambulatory phase. During the period of 6 yrs. the use of SM was markedly reduced (21.8%) while the use of PZA increased from 14.6% to 55.0%. At least four drugs were used in 22.5%. In 36.2% mycobacteria were found only before starting treatment. After four weeks treatment further 45.1% were negative. Adverse reactions were registered in 9.3%. Concomitant diseases rendering the treatment were observed in 24.7%. Ten patients died because of tuberculosis. Until now only 3 patients had relapses. Controlled treatment is valuable and therefore recommended.
