Abstract

We studied the effect of dosed normobaric hypoxia during 28 days on functional state and physiological regeneration of liverparenchyma. After completion of experiments in 3 and 9-month old rats we observed an increase in the amount of hepa-tocytes per unit of tissue area, with hypertrophied nucleus and decreased cytoplasmic area. IGF-I gene expression in 9-month old animals was increased. Thus, our study suggests that normobaric hypoxia stimulates physiological regeneration of liver parenchyma in young and adult rats.
