Bronchial secretions from 207 children suffering from various pulmonary diseases and from 15 healthy controls were tested concentration of IgA, IgG, lactoferrin and lysozyme. The results obtained suggest that in many cases of chronic lung diseases in children the levels of lactoferrin and immunoglobulins, especially secretory IgA, are very low. In severe infections (cystic fibrosis, bronchiectases) significant increase of IgG concentration was observed.

The concentration of immunoglobulins, lactoferrin and lysozyme we compared in bronchial secretions obtained from children with various chronic lung diseases. The IgG, lactoferrin and lysozyme, but not secretory IgA, concentrations were shown to be increased during chronic inflammatory response.

The condition of tonsils was investigated and the levels of serum IgG, IgA, IgM and lysozyme were measured in 305 ten-year-old children from three localities of the Central-Bohemian Region. The tonsils were not enlarged in 30.8% of children, in 26.2% they were enlarged, in 35.5% furrowed and in 7.5% of children tonsillectomy had been carried out. Mean levels of IgA were significantly higher in two localities in children with enlarged tonsils, insignificantly lower in children with furrowed tonsils and lowest in tonsilectomized children. The difference in the distribution of IgM levels were significant between girls with enlarged furrowed tonsils. The levels of lysozyme were not correlated with the finding in the tonsils, but a significant difference was found in the groups with enlarged tonsils between the three locailties under observation and in the groups with furrowed tonsils between two localities. The importance of the findings observed is discussed from the point of view of a possible influence of air pollution in two of the three localities under study.

Tear lysozyme and gamma A globulin (IgA) concentrations were determined during a 24 hour period using a simple quantitative method. Tear lysozyme was significantly elevated between the 9 and 12 AM periods, and reduced during the sleep periods from midnight to 3 AM. Tear IgA concentrations showed individual variability, but no discernible diurnal rhythm.

The content of secretory IgA (sIgA,) lysozyme and albumin was studied in the saliva of 40 health-service employees of different ages without evident signs of disease. The levels of lysozyme decrease significantly with the advancing age whereas those of sIgA and albumin do not decrease up to the age of 55. The levels of lysozyme and sIgA show a significant mutual correlation.

The effect of gentamicin sulphate and its combination will prodigiozan on antibody formation in experiments and the levels of the immunobiologic reactivity of patients with purulent inflammatory processes was studied with a purpose of developing rational schemes of antibiotic therapy of infectious diseases. A decrease in the titers of the antibodies to Aeromonas and the number of antibody-forming cells in the spleen was noted on repeated administration of gentamicin to albino mice in a dose of 20 mg/kg. This was prevented by the use of prodigiozan in a dose of 500 micrograms/kg once every 4 days. The use of gentamicin in patients with purulent inflammatory diseases in doses of 40 or 80 mg twice a day for 7--10 days had no significant effect on the titers of IgA, IgG, IgM, lysozyme blood serum levels, serum bactericidal activity and absorption activity of the peripheral blood neutrophils. Still, it induced a marked suppression of the neutrophil digestive capacity as compared to the initial levels, especially on administration of gentamicin in a dose of 40 mg twice a day. An increase in the level of IgM and no suppression of the neutrophil digestive capacity were noted after completion of the therapy in the patients treated with gentamicin administered in a dose of 40 mg twice a day and prodigiozan administered in a dose of 50 micrograms once every 4 days. It is recommended to use prodigiozan in combinaed therapy with gentamicin for correction of the changes in the specific and nonspecific protective forces of the host.

Immunoglobulins IgA and IgG levels and Lysozyme-activity were examined in the vaginal fluid of 70 pregnant women and 30 non-pregnant women where microbiological examinations did not detect any pathological microorganisms. To confirm the local character of immune factors produced in the female genital tract, these factors were also examined in the sera. An increase of class A immunoglobulins was noted in the vaginal fluid and examined sera. IgA/IgG ratio as well as statistical calculations confirmed the local origin of antibodies within the classes. The lysozyme activity was 10 times greater in the vaginal fluid than in the sera. Both factors are relatively simple to determine and in women with recurrent inflammatory conditions of the vaginal tract can be used as indicators of the local immunity state.

74 patients with untreated cervical cancer (FIGO II and III) were skintested with a battery of recall antigens, and also sensitised and challenged with DNCB. A significant reduction of reaction to Tuberkulin, Varidase and also to DNCB was found in patients with stage III in comparison to healthy females of the same age group. Significant changes in immunoglobulin levels, increase of IgA and decrease of IgG were observed in the cancer patients. Serum lysozyme values were the same as in the control group.

The relative clearances of albumin, transferrin, haptoglobin, IgG, IgA, and IgM and the relative excretion of immunoglobin free lambda- and kappa light chains, lysozyme, and beta2-microglobulin were measured in 24 patients who had recently received renal transplants. Eleven out of 13 acute rejection episodes were predicted 1 to 5 days before the clinical diagnosis was made, and in 2 patients the clinical diagnosis of rejection and the prediction were made simultaneously. Successful antirejection therapy was followed by a decrease in protein excretion; in irreversible rejection episodes protein excretion continued to increase in spite of antirejection therapy. It is recommended that the relative clearances of IgG and haptoglobin be measured daily in patients recently treated by renal transplantation.

Middle ear effusions from 100 patients (ages 6 months to 10 years) with serous otitis media were examined. The IgA, IgG, and lysozyme were demonstrated at a higher level in the effusions than the corresponding sera, indicating local production. The mucoid type contained higher level of immunoglobulins and lysozyme compared to serous type effusions. Bacteria were found in 77 percent of the effusions by means of a smear, and 52 percent yielded positive bacterial culture. The incidence of positive culture in effusions of the patients less than 6 years of age was 60 percent, while the group older than 6 years old was 32%, and the group over 8 was only 22 percent. Bacterial recovery rate was inversely related to the dramatic increase with age of IgA and IgG and lysozyme levels in effusions.
