[The network organization of medical research in the US Armed Forces].

The current article is dedicated to the network mode of medical scientific research organization in the US Armed Forces exploring the Armed Forces Institute of Regenerative Medicine as an example. The following features of the institute are examined: the structure, definition of scientific research goals and tasks, financing, management, areas of research, the next generation of the institute. In conclusion some characteristic features of network scientific research establishment and required legal conditions are determined.

[Military postgraduate courses at the Military Medical Academy: history, current state and prospects].

Training of scientific and scientific-pedagogical staff is one of the most important tasks of any high school. The problem of staff training arose in the Kirov Military Medical (Medical Surgical) Academy before its official foundation. In 1741 first scholars were sent abroad for the preparation of theses. The scholars were supposed to return to the hospital schools for teaching activity. Since 1802 scholars have defended their theses in the Academy. In 1858 special medical institute, the prototype of the Institute for postgraduate military studies was established. Many outstanding scientists studied in the Academy and brought name of the Academy into repute. At the present time, the Institute of postgraduate military studies (postgraduate) of the Kirov Military Medical Academy continues to train scientific staff. The Institute of postgraduate military studies remains one of the most successful institutes in Russia.

[Endothelial dysfunction on initial stages of arterial hypertension among men of young age and it's connection with vascular risk factors].

Frequency of display endothelial dysfunction, arising on the initial stages of development arterial hypertension is investigated, depending on vascular risk factors. The main group was made by 86 men with arterial hypertension I-II stage, group of the control--practically healthy 50 men. Vasomotor endothelial function defined on a degree of vasodilatation a humeral artery in reply to reactive hyperemia. Damage signs of endothelial monolayer estimated by quantity of free circulating endothelial blue blood cells. It is established, that the simultaneous combination of functional or structural vascular infringements among persons with normal blood pressure was registered in 3 times less often in comparison to patients with an arterial hypertension (p<0,01). At the main group at a simultaneous combination inadequate vasodilatation and endotheliaemia occurrence risk factors in 1,5 times is higher, than at their isolated display (p>0,05).

Analytical Application of Silica Gel Modified with Didecylaminoethyl-beta-Tridecylammonium Iodide.

Sorption of a high molecular weight quaternary ammonium salt, didecylaminoethyl-beta-tridecylammonium iodide (DDATD) on different types of sorbents was investigated. The nature of reagent adsorption on silica gel was examined by spectroscopic and computer methods. The sorption of anionic metal complexes of cobalt, copper, zinc and manganese on silica gel modified with DDATD was studied. The possibility of recovery of cobalt and copper thiocyanate complexes and their further atomic absorption determination is shown. Modified sorbent was applied to cobalt chemiluminescence and determined in natural water and a nickel preparation (detection limit, 2 mug/l.).
