[Effect of peptide immunomodulators on microlymphodynamics].

Study of changes of some microlymphocirculatory parameters on the mesentery of anesthesized female albino rats in application of immunomodulators in 3-4 concentrations showed the following. Lympholin and gordox caused no changes of the studied parameters (tonic activity, rate and amplitude of rhythmic phase activity, rate of lymph flow). With gradual increase of concentration, Tactivin caused a greater constriction of the lymph vessels with a reduction of the amplitude of contractions.

[Methodological approaches to a statistical analysis of the data from a population survey of children in a study of the causes of obesity].

To elaborate unified criteria for the physical development evaluation in children, a comparison was made of two populations of children in the Estonian SSR: with normal and excessive body mass (EBM). The investigation was conducted by the cohort type, the children were divided into groups according to their age, sex, residence and nationality. To study the influence of the above factors on the distribution of Quetelet's index (the basic parameters of EBM) in the population of children in the Estonian SSR, a criterion was used, characterizing variations of the populations with respect to each of the factors with due regard for the rest factors.

[Characteristics of the actual nutrition of Estonian and Finnish children].

The initial stage of the joint Soviet-Finnish scientific investigations of the risk factors of obesity in children is presented in the paper. The investigations were conducted by the Nutrition Department of the Institute of Nutrition of the Academy of Medical Sciences of the USSR, in the Estonian SSR, and the Helsinki University in Finland. The authors have analyzed daily intake of varying food products by children aged from 1 to 15 years, as well as daily average-energy consumption with food ration as a whole and separately at the expense of protein, fatty and carbohydrate components of food rations of these children.
