[Approaches to the treatment of hypertension].

The article criticizes a standard approach to essential hypertension treatment based for the most part on b-adrenoblokers, calcium channel blockers and angiotensin-converting enzyme inhibitors. The author proposed an individual approach to managing hypertension based on Lang neurogenic theory with taking into consideration different types of hypertensive attacks.

[Combined use of anaprilin and thiamine in the treatment of ischemic heart disease].

In 60 patients with stable functional class II exertional angina with hyperkinetic type of circulation, baseline hemodynamics was studied following a 2-week treatment. A negatively chrono- and inotrophic effect was observed with taking anaprilin in a dose of 160 mg per day and a dose of 80 mg per day combined with 2 ml of 5 per cent solution of thiamine-chloride in injections. No effect was elicited with an 80 mg/d anaprilin without thiamine.

[Use of ascorbic acid for raising clinical response to long-acting nitrates].

The data of clinic observation and ECG-monitoring show that ascorbic acid significantly increases antianginal vasodilatory effects of nitroglycerine thus preventing from development of ischemic miocardial reaction in response to complamin injection. Incubation under anaerobe conditions of ascorbic acid solution with NO-donors (sodium nitrate, nitroglycerine) or with the blood of ischemic patients who had been treated for a long time with long-acting nitrovasodilators, results in liberation in Varburg vasculium of gas bubbles identified as nitrogen oxide according to hemoglobin nitrosylation. Activation of endogen NO-donors with ascorbic acid and taking antilogs of antianginal effects of exogenous nitroglycerine makes it possible to substantially increase the efficiency of nitratotherapy and nitratoprophylaxis of angina pectoris.

Reduction of nitrite by glycosylated amino acids and glycosylated albumin.

Glycosylated amino acids and glycosylated human serum albumin reduce nitrite to nitric oxide under anaerobic conditions. The amount of nitric oxide produced was recorded by generation of nitrosoHb from deoxyHb. Without preincubation after the addition of sodium nitrite, glucose or a mixture of glucose with amino acid or serum albumin did not cause spectrophotometrically detectible transformation of deoxyHb into nitrosoHb.

Reduction of methemoglobin and ferricytochrome c by glycosylated amino acids and albumin.

The fraction of Amadori products gradually decreased during heavy glycosylation of amino acids and human serum albumin while the amount of a colored product with the maximum fluorescence at 420 nm decreased. The addition of the produced ketoamines of amino acids to the solution of native albumin quenched its own fluorescence due to generation of a Schiff base with amino groups of the protein. Carbonyl-containing Amadori products obtained during the early steps of glycosylation were less potent electron donors than amino acids more heavily modified by the carbohydrate.

[Is oxythiamine an antivitamin?].

The review deals with biological and medical aspects of oxythiamine biochemistry with special reference to the facts which contradict the traditional antivitamin conception. Alternatives to the coenzyme mechanism in interpreting the metabolic effects of this vitamin B1 derivative are discussed.

[Functional activity of the adrenal glands and the hormone-protein interactions in patients with hypertension with a complicated course].

Patients with essential hypertension and hypertension complicated by coronary heart disease showed adrenal glucocorticoid activation along with reduced transcortin binding capacity (TBC). The addition of circulatory insufficiency (stage I and IIB) resulted in a decrease of the functional adrenal reserve and further diminution of TBC due to a reduction of protein binding sites concentration, and sometimes (stage IIB) also a decrease in the protein affinity of steroids. A correlation between TBC and plasma protein level was found.

[Effect of the B-group vitamin complex on the blood content of saturated and unsaturated fatty acids in patients with ischemic heart disease and hypertension].

Gas-liquid chromatography was used to study the blood content of saturated and unsaturated fatty acids, under the influence of the functionally-associated vitamin-B complex, in 45 patients with coronary heart disease and essential hypertension. The vitamins were given daily in the following doses: thiamine diphosphate 50 mg, riboflavine 40 mg, calcium pantothenate 200 mg, nicotinic acid 200 mg and lipoic acid 50 mg. Favourable shifts leading to positive clinical effects were recorded in the fatty acid metabolism after 10-day taking the vitamin-B complex: the content of unsaturated (linoleic and arachidonic) fatty acids increased while that of saturated (stearic and palmitic) fatty acids decreased.

[Effect of lipoic acid, biotin and pyridoxine on blood content of saturated and unsaturated fatty acids in ischemic heart disease and hypertension].

Gas liquid chromatography was used to examine the effect of treatment on the blood content of saturated and unsaturated fatty acids in 75 patients with coronary heart disease and essential hypertension. There were three groups of patients. The first group (30 subjects) received lipoic acid, whereas the second one (30 subjects) were given biotin nd pyridoxine.
