[Diagnosis of cutaneous graft-versus-host disease: pathomorphological aspects].

Objective: To study the differential diagnostic value of histological and immunohistochemical signs in skin biopsy specimens in graft-versus-host disease (GVHD).

Material And Methods: Hematoxylin- and eosin-stained skin biopsy specimens from 50 patients with GVHD and 10 patients with toxicoderma were examined; immunohistochemical reactions using antibodies against CD3, CD20, CD4, CD8, FOXP3, CD56, CD1a, and CD68 were performed. The significance of differences between the groups was estimated using the chi2 and Mann-Whitney tests.

[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.

[Oxidative and hydrolytic deterioration of palm oil and fat products based on it under various conditions of storage and transportation].

Studies have been conducted on the effect of storage conditions for refined deodorized palm oil on the quality and safety: in containers made of ferrous metals (mild steel) at unregulated temperature, in sealed plastic bags at the temperature -20 degrees C in stainless steel under stratification of nitrogen at the temperature of 40+/-1 degrees C. The choice of the objects of study determined by the normative documents of the Russian Federation governing the transportation and storage of vegetable oils and fat products based on them. All samples of palm oil with peroxide value of 1,0 to 1,5 meq O2/kg indicated the presence of a weak foreign taste, is not peculiar impersonalfat, the samples with peroxide value above 1,5 meq O2/kg were observed pronounced off-flavors and odors characteristic of stale oil.

[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.

[Influence of different iron compounds on lipid complex of vitamin fortified wheat flour under storage].

Influence of different iron compounds at combined vitamin fortification on hygienic and biochemical properties of freshly grounded first-class wheat flour under storage was studied. It proved, that more intensive oxidative and hydrolytic processes take place in the lipid complex of the flour, fortified with ferrous sulfate heptahydrate.
