Age features of lipid peroxidation and antioxidant protection processes in girls and women tofalar ethnic groups

Abstract

Research objective: studying lipid peroxidation and antioxidant protection processes in girls and women of 3 age groups living in Tofalariya (ethnic tofalars). Spectrophotometric, fluorometric and statistic methods (Student’s parametrical criterion and Fisher's coefficient) were used. It was determined that decrease of lipid peroxidation and antioxidant protection processes activity takes place in puberty period. We marked increase concentration of lipid peroxidation products and retinol. The elder age period is characterized by the raised intensity of peroxidation processes.

Sperm Quality and Oxidative-Antioxidant Profile in Men Living in Different Regions of Siberia

“…The decrease in the indicators of spermatogenesis in men, demonstrated by studies in recent years, could be caused both by the increasing impact on the human body of damaging factors found in the environment, at work and in everyday life, and by the lack of vitamins and microelements in the diet of modern men. (1,7,8,10) According to a comprehensive assessment of nutrition in a number of regions of the world, there has been a sharp (2-3 times) decrease in the amount of food consumed by humans. (12) A decrease in the volume of food also reduces the amount of intake of necessary nutrients-minerals, vitamins, amino acids.…”

“…Geographic and ethnic variability of the norm and pathology play an important role. (1)(2)(3) The results of many years of fundamental and clinical research indicate that differences exist in the most important physiological constants of the body in the functioning of the reactions of the neuro-immune-endocrine system to the impact of inadequate exogenous and endogenous factors, as well as in the morphological characteristics and adaptive shifts in various environmental conditions. (4)(5)(6)(7)(8) Male subfertility, deviations from the norm in sperm counts, and infertility are very common phenomena at the present time.…”

“…E-mail: nakurashova@ yandex.ru as contemporaries, indicate that the lack of vitamins and microelements is one of the reasons for the progressive decline in spermatogenesis indicators. (1,8,10) At all times, nutrition and the ability to reproduce offspring have been closely interrelated. It is known that due to changes in the habitat, and to the nature of nutrition and lifestyle in a modern person, there is a lack of vitamins and microelements (or a violation of their metabolism), which is largely responsible for disorders of the reproductive system.…”
