[Nutrition and nutritional status in infants and children of early years of life in Russian Federation].

The study of the nutrition and the nutritional status children of the first year age and children earliest age were conducted on nationally representative surveys (2500 children, 2-24 months) the Institute of Nutrition, Russian Academy of Medical Sciences with the Institute of Sociology Russian of Academy of Sciences, Gerber Product Company and Nestle Company in 2006. The level the frequency of breast feeding had among children 1 m.--80%, 2-4 m.--70%, 4-6 m.--60%. The lowest body mass Z-scores were registered 0.5-5.0% among of children, the tendency of obesity increase in the age were registered from 1.6 to 13% of children. Calculations of chemical composition and energy value of actual nutrition have show according to the values requirements.

[Dietary intake of antioxidant vitamins in Russian population].

Aim of present study was the getting data on dietary intake of antioxidant vitamins in Russian population in 1995-2002. The consumption of food was estimated by 24-hour recall methodology in course of Russian Longitudinal monitoring surveys of economics and health. Mean intake of vitamin A is less than recommended level and 25th procentile is near to zero. Mean and median of vitamin E intake are equal of recommended level. Dietary intake of vitamin A per 1000 kcal is maximal in group of children 0-6 year old and in adults aged 30-60 y. Nutrient density of daly diet in relation to antioxidant vitamins has maximal level in old group of population 60+ and minimal level in 6-18 year old children.

[Limiting the allowable concentration of zearalenone in processed grain products]. / O predel'no dopustimykh kontsentratsiiakh zearalenona v produktakh pererabotki zerna.

The distribution zearalenon (ZL) in products of processing of contaminated wheat, barley and maize grains was is investigated. Results of the data analysis on the investigation of an actual nutrition of the population in Russia is presented; the share of products of processing of contaminated wheat, barley and maize grains as part of the total ration was determined Varied values of Maximum Acceptable Concentration (MAC) of ZL based on the obtained results are offered: 1 mg/kg--for wheat, barley and maize grains; 0.2 mg/kg--for main products of grain processing, viz flour and groats. The application of these MAC-values for ZL ensures the conformity between the ones for raw materials and for products of processing of raw materials, as well as the limitation of the maximum possible ZL--intake within the bounds of Acceptable Daily Intake (ADI) for a man.

[Diet in low-income families: adult working population]. / Pitanie v bednykh sem'iakh: vzrosloe trudosposobnoe naselenie.

The epidemiological research of the nutrition and health status of the low-income people was held in five regions of the Russian Federation. The analyze of the nutrients, energy, micronutrients and of the main groups of foods consumption in the families with the different level of income was executed. The estimation of the nutrition status was made with using body mass index. The results of this work showed the need of the development of nutrition support in social service and using the medical criteria for this support in low-income people.

[Nutrition of pregnant women in Moscow and Ekaterinburg: requirements of basic nutrients]. / Pitanie beremennykh zhenshchin v Moskve i Ekaterinburge: potreblenie osnovnykh pishchevykh veshestv.

Nutrient and energy intake was studied in 892 pregnant women during III trimester of pregnancy. Daily total protein intake was 65-66 g and animal protein made up 60% of total protein intake. Total fat consumption was 80-81 g, carbohydrates intake was 240-250 g. Total energy intake in Ekaterinburg's and Moscow's pregnant made up 2031 and 1978 kcal respectively. Body mass gain from I to III trimesters have formed about 9 kg or 0.41 kg per week. Body mass index (BMI) averaged 25,1 and 25,7 in Ekaterinburg's and Moscow's pregnant on day of survey. About 2,5% of women had BMI lower than 19,8. The results were compared with data of developed countries and conclusion was made about sufficient energy and macronutrient intakes, but fat intake was moderately high and formed 33-35% of total energy. The usefulness of Russian RDA are discussed for evaluation of results of dietary surveys.

[Chromatographic method of determining membrane epoxide hydrolase activity]. / Khromatograficheskii metod opredeleniia aktivnosti membrannoi époksidgidrolazy.

A new method for determination of the activity of epoxide hydrolase (EC 3.3.2.3), an enzyme of the 2nd phase of the system of drug metabolism, in rat liver microsomes was developed. 9,10-Epoxy-9,10-dihydrophenanthrene was used as a substrate. The quantitative determination of 9,10-dioxy-9,10-dihydrophenanthrene was performed according to the method of the internal standard by HPLC in aqueous a cetonitrile on octylsilica gel with fluorescent detection. 1-Naphthol was used as the internal standard. The method is simple and requires no preliminary extraction of the sample and preparation of the derivatives. It is highly sensitive and rapid: the time of the chromatographic analysis is not more than 3 minutes. The error does not exceed 5 per cent.
