Effect of dietotherapy on the magnesium content of the blood serum of ischemic heart disease patients

Examination of patients with chronic coronary heart disease who suffered myocardial infarction has shown that most of them had a high blood serum content of magnesium. The magnesium content was lowered in 25% of the examined and was maximal in serum of the patients under 40 years. A positive correlation of the magnesium content to the serum content of beta-cholesterol and a negative one to the content of pre-beta-cholesterol and triglycerides were noted. After dietetic management a tendency was observed toward a 24% decrease in the magnesium content in obese patients and a 20% decrease in patients with normal body weight. Both groups demonstrated a reduction (but within normal) in the high magnesium content and a moderate elevation of the initially lowered content. The measurement of the magnesium content in blood serum cannot be regarded as an informative enough test for revealing the role of magnesium in the pathogenesis of coronary heart disease.

The erythrocyte lipids of the peripheral blood and myocardial dystrophy in patients with iron-deficiency anemia

Lipids of peripheral blood red cells (total lipids and phospholipids, triglycerides, free fatty acids, cholesterol, cholesterol ethers, lysophospholipids, sphingomyelins, phosphatidylserins, phosphatidylethanolamines, phosphatidylcholines, cardiolipins, phosphatid acids) were assessed in correlation with wave T height on resting ECG. It is shown that iron deficiency anemia patients develop shifts in red blood cell lipid composition contributing to the onset of myocardiodystrophy. The correction of the lipid composition defects is an additional factor decreasing dystrophic processes in the myocardium.     

Heat transfer in inverted annular mode of steam-water flow

A modified version of Hammouda’s model for heat transfer in the inverted annular flow mode region is proposed, central to which is the use of temperature factor in calculating the Nusselt number and a new approximation of the influence coefficient θ. As a result, good agreement with experimental data for steam-water flow is obtained. Criteria for selecting the length integration step in computation codes are suggested.     

Importance of the qualitative composition of dietary proteins in the dietotherapy of ischemic heart disease patients

The effects of two isocaloric antiatherosclerotic diets (containing 120 g protein) differing in the amino acid composition of protein sources introduced were studied and compared in patients with coronary heart disease. Conventional protein sources were used in the first diet, whereas in the second diet, 15% of protein (by weight) was replaced by soybean protein isolate. A study was also made of the effect of dietetic management on lipid metabolism in blood serum. Hemocoagulation, capillary permeability, the kallikrein-kinin system, and immune responsiveness. An increase in the hypolipidemic effect of the diet was noted together with a decrease in the activity of the kallikrein-kinin system, capillary permeability, and body autosensitization upon introduction into the diet of soybean protein isolate. The increase of the protein quota as well as that attained by means of introducing in the diet of soybean protein isolate reduces the therapeutic effect of the diet on hemostasis.     

Effect of diet therapy on indices of the activity of the plasma kallikrein-kinin system of young and middle-aged ischemic heart disease patients

Young and middle-aged patients with coronary heart disease manifested an increase in the activity of kallikrein and BAEE-esterase together with a reduction in the levels of prekallikrein and alpha 2-macroglobulin. The maximal shifts were seen in young patients and in patients who sustained myocardial infarction less than a year before examination. High kallikrein level was associated with hypertriglyceridemia and disordered fibrinolytic activity. Dietetics promoted the normalization of the disordered parameters, particularly in patients whose diet included soybean.
