RESUMO

The efficiency of magnetic laser therapy was evaluated in patients with essential hypertension (stages I and II). The role of angiotensinogen, angiotensin-converting enzyme, type II bradykinin receptor, and endothelial nitrogen oxide synthetase gene polymorphism in the realization of hypotensive effect of magnetic laser therapy was evaluated. The hypotensive effect of magnetic laser therapy depends on the polymorphism of the studied genes and is maximum in patients with MM polymorphism of angiotensinogen gene and DD polymorphism of angiotensin-converting enzyme gene. Additive interaction between angiotensin-converting enzyme and angiotensinogen genes in the formation of hemodynamic effects of magnetic laser therapy was detected.

RESUMO

We investigated the role of gene polymorphisms in angiotensin-converting enzyme (ACE), angiotensinogen, endothelial NO (eNO) synthase, and bradykinin receptor B2 in determining the cardiovascular system structure and function in hypertension and "athletic heart" syndrome. Using a PCR-based method, 114 hypertensive patients and 94 athletes were genotyped for I/D polymorphism of ACE, M235T angiotensinogen (ANG), Glu298 Asp endothelial synthase (eNOS), and type 2 receptor for bradykinin (BDKR2). Echocardiography and a 24 hour blood pressure monitoring being performed. The (+)-allel of BDKR2 gene was associated with the left ventricular hypertrophy and greater wall thickness in athletes and hypertensive subjects. The hypertensive patients, that were homozygous for Glu298 allele of eNOS, demonstrated a lower level of diastolic blood pressure than did those with Glu298 Asp and Asp298 Asp genotypes. At the same time, the ACE and AND gene polymorphisms displayed no association with the cardiac structure and function.

RESUMO

The authors studied the effect of alpha-tocopherol acetate and nicotinamide on lipid peroxidation and antioxidant enzyme defense (AED) in red cell membranes of 61 patients with new-onset insulin-dependent diabetes mellitus. Lipid peroxidation products were found in excessive quantities, whereas enzymes of the cell antioxidant defense were on the decrease. Combination of tocopherol with nicotinamide as adjuvants to conventional insulin therapy promoted normalization of lipid peroxidation and AED, improving beta-cell function. It is believed justified to introduce antioxidant treatment early in the disease onset to prevent toxic damage to beta-cells and vascular endothelium induced by lipid peroxidation products.
