[Humoral immune response to the retinal S-antigen in premature infants and its role in the development and course of retinopathy of prematurity].

The humoral immune response to the retinal S-antigen was studied in premature babies with active and cicatricle stages of retinopathy of the premature (RP) and in the controls (102 serum test). The presence of antibodies to the S-antigen of classes IgG and IgM was established by the enzyme multiplied analysis and by an authors' developed test-system. A definite specific humoral response to the S-antigen correlated with the nature of the course and prognosis of the disease was found in 71% of cases.

[Netilmicin in the complex therapy of pneumonia in newborns].

Clinical efficacy of netilmicin was evaluated at 22 newborns (body weight from 1000 to 3600 g, delivery on pregnancy period from 28 to 41 weeks) with pneumonia caused by artificial pulmonary ventilation. Pneumonia was moderate at 13 patients and severe at 9 patients. Microorganisms isolated from tracheobronchial aspirates were mainly (in 19 cases of 22) susceptible to netilmicin.

[The efficacy of the eubiotic bifacide when used in the combined antibacterial therapy of newborn infants with infectious-inflammatory diseases].

The efficacies of bifacid and bifidumbacterin were studied comparatively in the correction of intestinal biocenosis in 60 newborns with infectious inflammatory diseases and intestine disfunction treated with massive doses of antibacterial drugs. The study showed that the use of bifidumbacterin was accompanied by significant disturbances in the biocenosis and by development of the intestinal syndrome. The protective action of the drug was observed after a short-term use only of one antibiotic and when the course of the bifidum therapy was continued after discontinuation of the treatment with antibacterial drugs.
