[Nutrition value of tropical and subtropical fruits].

The article is devoted to the study of the chemical composition of tropical and subtropical fruit (avocado, papaya and mango), which are now in great numbers are on the appeared on the Russian market. Due to use technology tropical and subtropical fruits can be implemented in almost all areas and regions of the country. Relatively low cost makes these products quite popular among the people.

[Composition and content of biologically active substances in rose hips].

The paper studies the chemical composition of the powders obtained from the pulp with the skins and seeds of fruits of wild rose hips. Research results have shown that the main fraction of the powder is dietary fiber, powder of seeds of insoluble fiber in 1,6 and 2,3 higher than in the powder of the fruit with a thin skin and pulp, respectively. The greatest amount of carbohydrates and protein found in powders and pulp of the fruit with a thin skin, and lipids predominate in the powder from the seeds.

[Comparative evaluation of zinc organic and inorganic form bioavailability in vivo].

Bioavailability of zinc complex with enzymatic hydrolysate of milk protein (EHMP) was studied in Wistar rats. Body mass, zinc content in os femoris and serum alkaline phosphatase activity were similar in rats receiving Zn-EHMP and zinc sulphate and were significantly higher than in animals fed with basal semi synthetic zinc-deficient diet. Apparent absorption of both Zn sources in rat's intestine was high (more than 70%) probably due to absence of plant dietary fiber in applied diet.

[The homeostatic changes of mineral and trace elements during of year at rheumatoid arthritis].

Dietetic therapy on a basis of specially developed variant anti-inflammatory, hypoallergic, hyposodium diets 10 PA, applied in Clinic of Institute of Nutrition Russian Academy of Medical Science for treatment of patients rheumatoid an arthritis, has yielded the positive clinical results comparable to efficiency of medicinal therapy. Two-year-old researches have allowed to receive representative enough (756 element-definition) a material on macro- and to microelement structure of plasma of blood of patients and its seasonal dynamics determined by interaction two neurohumoral systems. For two elements--K and Zn, changes of concentration in whey of blood during one year it was revealed not, but for others five investigated elements--Na, Ca, Mg, Cu and Fe, curves with appreciable maxima and minima of contents which did not coincide with similar dependences for healthy people and about earlier investigated pathologies of other genesis were observed.

[The season changes of mineral and trace elements contents in blood patients with ulcer pathology gastric and intestinal duodenal].

There are two concepts of homeostasis microelements: a traditional one, considering homeostasis as a constancy of internal media of alive organisms, and an alternative, examining the change of structure of these media in time as a consequence of change of external factors. In the first concept the deviation of concentration of a microelement from norm in whey of blood is considered a diagnostic attribute of microelementose (deficiency or surplus). In the second concept, on the contrary, it is supposed, that such deviations can have the adaptive character assisting to an organism in struggle against illness.
