Abstract
The results of studies of alimentary correction of the efficiency of gas exchange in the lungs by the example of students and teachers of an engineering university with daily use of foods with known bio-correcting properties: 3.5 g of wheat germ oil (WGO), 50 g of wheat germ meal cake (WGMC), are presented 6.5 g of concentrated tissue fish oil (CTFO) and their combinations with the biomass of the consortium of lacto- and bifidobacteria (10 g). The efficiency of gas exchange processes was evaluated based on the analysis of the respiratory coefficient, the concentration of carbon dioxide (CO2) and oxygen (O2) in the exhaled gas mixture was determined using a TESTO-310 gas analyzer, an MDG-1201 capnograph, the values of which were recorded before and after daily use of the studied products during 30 days. The experimental group consisted of volunteers – teachers and university students aged 16 to 65 years, divided into 3 age groups: 16-24, 25-44 and 45-65 years old. It was established that the most effective antihypoxic drug is WGMC, in all age groups, the increase in average RR values amounted to 0.041 units, and 4.8% relative to the initial values. When using WGO, the change in RC was 0.032, an increase compared to baseline – 3.7%. In the 1st, 2nd and 3rd age groups, the average change in RC was: 0,031, 0,036 and 0,043 units, relative to the initial indicators, the increase was 3.5, 4.2 and 5.0%, respectively. It is proved that the combination of the studied biocorrector with the active forms of probiotic microorganisms provides a more active antihypoxic effect for all the studied products in all age groups. The effectiveness of the WGO was increased, the increase in RC was 0.049 units, for CTFO – 0.024 units. The growth of RC relative to the initial values was 5.7 and 2.9%, respectively. The synergism of the action of biocorrectors in combination with probiotics, by age groups amounted to – 0.035, 0.033 and 0.038 units, which is 4.1, 3.8 and 4.5% relative to the initial indicators.
Highlights
The ecology of the modern world, especially megacities, leads to an increase in the oxygen demand of our body, the deficiency of which is not covered during the day
Assessment of the respiratory coefficient values in all age groups showed that the most effective antihypoxic drug is wheat germ meal cake (WGMC), the increase in the average RC values for all age groups amounted to 0.041 units
Based on the analysis of the results of experimental studies, it was found that the studied biocorrector wheat germ oil (WGO) and WGMC can be attributed to nutritional factors of biocorrective action, providing increased efficiency of lung gas exchange in age groups from 18 to 65 years
Summary
The ecology of the modern world, especially megacities, leads to an increase in the oxygen demand of our body, the deficiency of which is not covered during the day. Long stay in rooms with a large number of people, a sedentary lifestyle, high mental and nervous stress are significant factors that influence the manifestation of hypoxia that occurs in the body with inadequate supply of oxygen to tissues and organs or in violation of oxygen utilization. One of the functions of breathing is gas exchange in the alveoli of the lungs, which ensures diffusion of molecular oxygen and carbon dioxide adequate metabolic demand for the concentration of these gases in arterial blood. An indicator of gas exchange efficiency is the respiratory coefficient (RC), calculated as the ratio of the amount of carbon dioxide (CO2) extracted from the lungs to the oxygen (O2) consumed over the same period of time, which shows which substances are predominantly oxidized [1, 2]. RC is 0.81, fat is 0.7, carbohydrate is 1.0, and with mixed nutrition, 0.82
