[The composition of the red blood and iron metabolism in the native population of the Republic of Sakha].

A field study in the Sakha Republic has been performed to characterize iron deficiency conditions in native population. Yakuts and Evens were examined for clinical, physiological, biochemical picture of the red blood cells and iron metabolism. European standards by total and fetal hemoglobin, reticulocytes, plasma iron metabolism in the native population were surpassed.

[The morphofunctional properties of the blood cells and iron metabolism in the native inhabitants of the Taimyr Autonomous Okrug].

The peripheral blood was studied in Dolgans, Nganasans and Nenetses, the native population living in Taimyr peninsula. The composition of their blood is really different from the European norm. In Aboriginals of Taimyr the activity of erythropoietin in blood plasma, the concentration of reticulocytes, the circulation in peripheral bed of diskocytes with one and many diverticula, the content of fetal hemoglobin are raised more than two times.

[The effect of alpha/beta and gamma interferon preparations on the functional activity of macrophages in experimental staphylococcal infections].

The preparations of alpha/beta- and gamma-interferons have been shown to stimulate the functional activity characteristics of mouse macrophages (phagocytosis, spreading, contacts with lymphocytes, bactericidal properties) obtained from the peritoneal exudate of intact animals and those infected with staphylococci. The immunomodulating action of gamma-interferon is more pronounced than that of the preparation of alpha/beta-interferon.
