[Phospholipids of the subcellular fractions of brain and liver tissues in rats in total oxygen starvation of the body].

The rate of phospholipid turnover in brain subcellular fractions differ from that in the liver tissue. Hypoxia of medium severity (pressure chamber 240 mm Hg) influences neither the content nor the turnover rate of phospholipids in liver subcellular fractions. Meanwhile in brain subcellular fractions, it results in a decreased phospholipid turnover rate. Severe hypoxia (less than 200 mm Hg) leads only to the suppression of the phospholipid turnover rate in the liver, whereas in the brain, it results in the decline of the phospholipid turnover rate as well as in the reduction of phospholipid content. Thus, the well-known concept of the higher brain sensitivity to oxygen deficiency as compared to the liver is exemplified by phospholipid turnover in subcellular fractions.
