[Side effects of antibacterial therapy with respect to hydrolysis and absorption of sugars in newborns].

Hydrolysis and absorption of sugars in the intestine were studied in 268 newborns at the background of antibacterial therapy of pneumonia and acute respiratory infections. It was shown that penicillins and cephalosporins induced impairment of lactose and sucrose hydrolysis followed by the development of persisting dyspepsia. The antibiotics also promoted the development of the syndrome of the malabsorption of monosugars.

[The biological effect of low-level radiation doses on the morphological composition of the peripheral blood in children].

Examination of 339 children at the age of 2 to 12 years, living in the caesium contaminated region (from 2 to 5 Ci/km2) has revealed that total radioactivity of their urine is, on the average, twice as high as that of children living in "pure" regions. Quantitative and qualitative changes were observed in the erythroid series, neutrophilic leukocytes, eosinophils and B-lymphocytes of the peripheral blood of children subjected to long-term low-level irradiation. It should be noted that the character and direction of these changes were a function of the children's age and the level of total radioactivity of their urine.

[Anthropometric indices of newborns and hormone levels in various periods of ontogenesis].

The relationships between anthropometric indices and the hormonal status in ontogenesis were investigated in newborns (137 girls and 151 boys aged 1.5-15); the venous blood levels of cortisol, corticosterone, testosterone, estriol, estradiol, progesterone, triiodothyronine, thyroxin, thyroxin-binding globulin, insulin and somatotropic hormone were determined by radioimmunoassay. At the time of investigation all the infants were practically healthy.
