Antioxidant activity of blood plasma of low-hill and middle-hill southern Altai aborigines

Antioxidant activity of blood plasma in Altai aborigines

“…To test the hypothesis on the effect of climatic and geographic factors on the AOA of blood plasma, the analysis of AOA of blood plasma in other low hill and middle hill Altai ethnic groups was performed. Along with southern Altaians (Altai Kizhy, Telengits) living in the low hill and middle hill regions [8], Gorny Altai aborigines include aboriginal Russian and Kazakh populations. Notably, Kazakhs live mainly in the middle hill region (1900 m above sea level), and Russians live in the low hill region (< 800 m above sea level).…”

“…Differences in the AOA of blood plasma between low hill and middle hill southern Altaians (Altai Kizhy) were described in [8]. To test the hypothesis on the effect of climatic and geographic factors on the AOA of blood plasma, the analysis of AOA of blood plasma in other low hill and middle hill Altai ethnic groups was performed.…”

“…It is natural to suppose that there are dif ferences in the AO system of body protection between some ethnic groups living under different climatic and geographic conditions. It was found that the AOA of blood plasma in low hill and middle hill southern Altai aborigines depended on climatic conditions and age [8]. However, there are very few data on the depen dence of AOA of blood plasma on the sex and type of diet.…”

“…Antioxi dant substances or antioxidants (AOs) contribute greatly to the above reactions, causing a wide range of physiological effects. They control the level of free rad ical oxidation reactions, prevent the accumulation of toxic oxidation products, are involved in various types of metabolism, can change the activity of other regulating systems, and protect the structural ele ments of cells [2].…”

“…According to the literature data, the antioxidant activity (AOA) of blood plasma depends on the health condition, stress level, type of diet [1,[3][4][5][6], age [6,7], climatic and geographic living conditions [8,9], and other factors. It is natural to suppose that there are dif ferences in the AO system of body protection between some ethnic groups living under different climatic and geographic conditions.…”
