Examination of patients of traumatologic department showed that patients elder than 60 years old accompanying cardiovascular diseases exposed to expressed depressive changes requiring medicamental correction.
A blood test can provide important information about the functional state of the antioxidant system. Malfunction of this system increases the concentration of free radicals and can cause oxidative stress. A difficulty in assessing oxidative stress is the lack of a universal method for determining the antioxidant activity (AOA) of blood components, because of their different nature.The objects of investigation were sera of 30 male patients with a diagnosis of alcohol dependence syndrome and healthy donors. Comparative investigation of total antioxidant activity (TAA) of human serum blood was carried out by voltammetric (VA), amperometric (AM) and chemiluminescent (HL) methods.All applied methods revealed that serum TAA of the patients with alcoholism is lower than TAA of healthy donors (control group); according to amperometric method the average value of serum TAA was 850 ±210 nA × s, and 660 ±150 nA × s for healthy donors and alcoholics respectively (p < 0.05). Similar trend was revealed by chemiluminescence and voltammetry methods. The results confirm that thiol compounds make a significant contribution to the antioxidant activity of serum. The average thiol concentrations were 0.94 ±0.34 mmol/l and 1.21 ±0.36 mmol/l (p < 0.05) for alcoholics and healthy donors respectively. Decreasing thiol concentration in blood of alcoholics leads to depletion of antioxidant systems of blood. However, the differences between the results of AM, VA and HL methods were significant, because they reflected different aspects of antioxidant activity.For objective assessment of antioxidant activity of biological objects, we suggest using methods based on different model systems.
Early combined prenatal screening for frequent chromosomal abnormalities and congenital disorders was organized in the Russian Federation in 2010 on the initiative of the Ministry of Health and Social Development and with the support of the Government of the Russian Federation in accordance with FMF guidelines. The first results achieved in the implementation of the activities of new screening model, and the evaluation of key indicators and the general condition of the early prenatal screening in the regions and the federal districts of Russia are presented.
