“…Presumably, overall augmenting swamping of the pericytic space inevitably impedes transudation and promotes the formation of a volumic mechanism of arterial hypertension [7]. Oxygen and metabolite insuffi ciency in the regulatory regions (for example, in the hypothalamus and kidneys) augmenting during this process can stimulate the mechanisms of circulatory perfusion and stabilize arterial hypertension.…”

In patients with essential hypertension, inhibition of glucose utilization in tissues was detected similar to that in diabetics. High levels of glycated compounds were found in cerebral, cardiac, and renal tissues of patients dead from coronary heart disease complicated and not complicated from diabetes mellitus and essential hypertension compared to victims dead from traumas. Experimental studies on rabbits and rats showed that the content of glycoconjugates in tissues did not increase in short-term (exogenous or stress-associated) hyperglycemia, while accumulation of glycoconjugates in pericapillary, pericytic, and cellular structures in long-term hyperglycemia caused deformation of tissue ultrastructure. These disorders can impede capillary transudation, initiate and stabilize arterial hypertension, and lead to multiple organ failure.

“…As was shown for ethylene epoxida tion catalysts, the parameters of the crystal structure (dispersion) of supported silver and a support can change the optimum amount of a promoter [9][10][11][12][13]. In view of this, we shall discuss questions of the optimum promotion of a 1,3 butadiene epoxidation silver cata lyst with consideration for the possible effect of cesium on the dispersion of silver in the synthesis of catalysts and their further thermal treatment.…”

Using the well known patent methods, we have synthesized 1,3 butadiene epoxidation α Al 2 O 3 supported catalysts containing 15 wt % of Ag and 250-1500 ppm of Cs (Johnson Matthey, H16P07). The physicochemical properties of samples are systematically studied by varying the dispersion of supported silver, the amount of an introduced promoter, and its distribution over the surface of a catalyst. Catalytic tests of samples show that the optimum amount of a promoter depends directly on the surface of a catalyst. With opti mum promotion, the steady state activity of catalysts is determined by the dispersion of supported silver. In the course of catalytic tests, it is established that the shape of kinetic curves is governed by the excess or lack of Cs in a catalyst, thus providing a method for optimizing the concentration of the promoter. An analysis of the energy dispersion spectra (EDS) is applied for the first time to study the distribution of Cs over the surface of promoted catalysts. It is shown that thermal treatment favors the uniform distribution of a promoter over the surface of a catalyst and shortens the time required to attain its steady state activity in catalytic tests. In our work, the steady state productivity of catalysts reaches 0.5 g of 3,4 epoxy 1 butene per gram of the cat alyst per hour, thus exceeding the claimed patent values.
