RESUMO

Vitamin status and bone strength have been estimated in 91 pregnant women (29.3 ± 4.6 years old) from Moscow by non-invasive methods. Sufficiency with vitamins C, B2, B6 has been evaluated by morning urinary excretion of ascorbic acid, riboflavin and 4-piridoxic acid determined by visual titration and fluorimetric methods. The rate of bone resorption has been measured by the ratio of urinary calcium and creatinine, determined by complexometric titration and spectrophotometrically. The study of the bone strength has been conducted using an ultrasonic densitometer (the speed of the ultrasonic waves along the cortical layer). The lack of vitamin C was found in 20.4% .of the women surveyed, vitamin B2--in 27.4%. Vitamin B6 deficiency was detected most frequently (90%). Excretion of vitamins B2 and B6 in women in the third trimester of pregnancy was lower as compared with the women in the first and second trimester. In 53.3% of the women surveyed an increase in urinary excretion of calcium per creatinine has been observed. Excretion of group B vitamins (especially vitamin B6, 1.75 fold, p < 0.05) in women taking vitamin supplements was higher compared to non-taking vitamins that indicates the better sufficiency of the organism with these vitamins. Among women who took vitamin complexes, inadequate supply with water-soluble vitamins C, B2 and B6 was detected less frequently (the difference was significant for vitamin B2) than among women who did not intake vitamin complexes (in 11.9, 27.7 and 42.4% vs 16.1, 54.8 and 48.8 %). The rate of bone resorption (Ca/creatinine) in women taking vitamins was smaller (0.19 ± 0.09 vs 0.24 ± 0.14, p > 0.05). Ca/creatinine ratio was within normal range in 40% of women who intake vitamins, while in women not taking vitamins--only in 22.2%; this value exceeded the upper limit of norm in the rest. The strength of bone was broken in women in the second and third trimester of pregnancy, having worse supply of vitamins. The percentage of agreement of the results of osteopenia diagnosis assessment (ultrasound densitometry and urinary Ca/creatinine) was 42.2%. Thus, the conclusion has been confirmed that the evaluation of the status of bone is possible only basing on the results of determination of several parameters.

RESUMO

Supporting of bone health is one of the main approaches to provide health in pregnant women considering intensive calcium and other mineral mobilization from mass bone that is necessary forforming fetus bone. This mobilization may lead to decrease of bone mineral density and development of osteopenia and osteoporosis. The important factors of development of bone impairment in pregnancy are nutrition and particular deficient consumption of protein, Ca, vitamin D. The possible role of reduced intake of pregnant women other nutrients remains unexplored. The aim of the research was estimating the prevalence of bone mineral density decrease in regard to the particular course of pregnancy and studying possible effects of key nutrients on bone mineral density in pregnant women. 131 women at different stages of pregnancy were involved in the survey. The bone density assessment was conducted using Bone Densitometer Omnisense 7000. As a criterion for bone density decrease in women used a Z-score, which was considered as normal to -1.0, as reduced from -1.0 to -2,0, and as significantly reduced when Z-score was less than -2,0. Analysis of the actual nutrition was performed by a 24-hour recording of 58 pregnant women. Normal bone mineral density was detected in 54 women or 41% of the total number of women surveyed. In 51 (39%) pregnant women reduced bone mineral density was discovered, and in 26 (20%) patients--significantly reduced bone density. There was a considerable deviation in pregnant patients' diet from the nutrition guidelines, which include, in particular, the high content of fat and saturated fatty acid, reduced intake of some micronutrients such as calcium, zinc, folic acid, ß-carotene, vitamins A, B1, E. However, differences in the actual consumption of nutrients in women with varying bone mineral density have been identified only in case of consumption of fat and energy value of diets, also Mn and I. So, it may be suggested that the differences in bone mineral density between women in our study are caused by genetic polymorphism, which leads to differences in the actual demand for nutrients, sufficient for prevention of bone decrease, in individuals.

RESUMO

In a consultative and diagnostic center "Healthy Nutrition" of Institute of Nutrition the nutritional status of 3500 patients (mean age 48.4 ± 0.3 years) liv- ing in the Moscow region, using a system Nutritest IP-3, including genomic analysis has been examined. In the analysis of dietary intake by an average review, increased energy intake due to excess intake of the total (44.2% energy) and saturated fat (13.6%) has been shown. 30.0% of patients were overweight and 34.1% were obese. Osteopenia was detected in 31.0% of men and 25.0% women, osteoporosis--20.9% and 30.3%, respectively. Analysis of the results of biochemical studies revealed increased cholesterol in 68.7% of patients, LDL cholesterol--at 63.9%, triglycerides-- at 22.5%, glucose--at 29.4%. The frequency of the occurrence of risk alleles of genes associated with the development of obesity and type 2 diabetes mellitus was: 47.8%--for the polymorphism rs9939609 (FTO gene), 8.3%--for polymorphism rs4994 (gene ADRB3), 60.2%--for the polymorphism rs659366 (gene UCP2), 36.6%--for the rs5219 polymorphism in the gene of ATP-dependent potassium channel.

RESUMO

Overweight appear one of the serious problem in European region WHO today. Obesity is polyetiological disease and result of different factors. The aim of the current studies was investigation of connection between consumption confectionary, fast food stuffs and soft drinks and body-mass index (BMI). At the beginning, was inspection of 434 schoolchildren 7-18 age old. As a result, was determined, that confectionary, fast food stuffs and soft drinks mach more popular, than ever stuffs. At the same time, was determined, that mean significance BMI was reliable above for children, who used confectionary, fast food stuffs and soft drinks frequently.

RESUMO

Hypophysectomy in rats is accompanied by a significant rise in PNPase activity in ribosomal fractions of the liver. Injection of growth hormone into operated animals produces inhibition of PNPase activity. The linear dependence "dose-response" was recorded with the use of a dosage range of 5 to 100 micrograms/animal. The action of growth hormone was most pronounced 18 hours following its single injection.
