[The role of the thrombocytic cationic protein (beta-lysin) in anti-infectious protection].

The biological activity of beta-lysin, cationite protein of thrombocytic origin with bactericidal activity, isolated from human blood serum was studied. The mechanisms of its bactericidal action was determined: the inhibition of bacterial catalase and peroxidase. The study revealed that the activity of beta-lysin in anti-infectious protection was due to both its direct bactericidal action and the enhancement the phagocytic reaction of the body by the stimulation of phagocytes and the opsonization of the pathogen.

[Characteristics of the functional systems regulating the growth and differentiation of the bony skeleton of healthy children and adolescents].

A study was made of the hypophysis, thyroid, adrenals and an x-ray appearance of hand bones in children of normal and accelerated physical development. Groups of children that were homogenous by chronological age, turned out heterogenous by morphofunctional parameters. Accelerated processes of morphological and age-sex differentiation of the body in children and adolescents with accelerated growth and development were indicative of the functional tension of the hypothalamo-hypophyseal system and gonadal, thyroid and adrenal activation.

[Aspartate, alanine, glutamate, malate glucose-6-phosphate dehydrogenases in Candida albicans].

Multiple molecular forms of aspartate, alanine, glutamate, malate and glucose-6-phosphate dehydrogenases were studied in the course of Candida albicans growth using electrophoresis in polyacrylamide gel. The isozyme spectrum and the activity of dehydrogenases were found to depend on the cultural age and the cofactor being used (NAD or NADP). The protein-antigenic spectrum and the composition of multiple molecular forms of dehydrogenases were compared in C.

[Androgenic function of the adrenal glands in children with acceleration of the growth and development].

A study was made of the urinary excretion of neutral 17-ketosteroids (sum total and individual fractions) in 65 accelerated children, aged from 7 to 16 years. The information on the excretion of androgenic compounds pointed to an earlier and increased functional activity of the adrenal cortex and gonads in children with acceleration of the growth and development.
