[Hemosorption in systemic vasculitis].

The present work summarises the experience gained with the use of extracorporeal hemoperfusion in 45 patients suffering from rheumatic diseases. During hemoperfusion, there was a decrease in the initially activated LDH, CPK, AST, ALT and AP. The reduction of the content of phospholipids and cholesterol in plasma and red blood cells is assessed as an adverse effect of hemoperfusion, since the content of phospholipids and cholesterol was under normal before hemoperfusion. The changes indicated point to the necessity of administering antioxidants and exogenous phospholipids.

[Activity of oxidative enzymes of the tricarboxylic acid cycle in rat myocardium in hypokinesia].

An experimental study in rats demonstrated that limited motor activity resulted in a drop of mitochondrial tricarboxylic dehydrogenase activity. Early dates of hypokinesia are characterized by a decrease in specific activity of dehydrogenases, and on days 45 and 60 the changes are due to smaller levels of mitochondrial fraction protein. The activity of cytoplasmic NADP-MDH and NAD-MDH undergoes changes by day 60 of immobilization, and that of NADP-ICDH by day 7 only. Hypokinesia disrupts the ratio between mitochondrial and cytoplasmic dehydrogenases. A twenty-five-day-long recovery period is not sufficient for the normalization of oxidative processes in the tricarboxylic acids cycle.

[Activity of oxidative enzymes of the tricarboxylic acid cycle in the liver of rats during hypokinesia].

The activity of oxidative enzymes of the Krebs cycle was examined in white rats during hypokinesia. On hypokinesia day 7 the cytosol activity of NAD-dependent isocitrate dehydrogenase (ICDH) increased and that of malic-enzyme decreased. On hypokinesia days 30 and 45 the activity of succinate dehydrogenase (SDH) and alpha-ketoglutarate dehydrogenase (alpha-KGDH) decreased, that of cytoplasmatic malate dehydrogenases (MDH) slightly increased, and that of NADP ICDH declined. On hypokinesia day 60 the total activity of mitochondrial dehydrogenases reduced due to a low protein content of the mitochondrial fraction, whereas the specific activity either remained unchanged (ICDH, NAD MDH, alpha-KGDH) or increased (SDH, NADP MDH). On recovery day 25 only the activity of mitochondrial NAD-dependent malate and isocitrate dehydrogenases returned to normal.

[Oxidative enzyme activity of the tricarboxylic acid cycle in rat skeletal muscles in hypokinesia].

The study of 165 rats exposed to 60-day hypokinesia demonstrated a decrease in the quantity of mitochondrial protein and a decline in the activity of mitochondrial forms of NADP-isocitrate dehydrogenase (NADP-ICDH) and NAD-malate dehydrogenase (NAD-MDH), as well as NAD-ICDH, succinate dehydrogenase (SDH) and alpha-ketoglutarate dehydrogenase (alpha-KGDH). The maximum decline in the protein content was seen on day 60, and in the enzyme activity on day 7. As the hypokinetic exposure continued, the activity of mitochondrial NAD-MDH and NADP-ICDH slightly increased. The NADP-MDH activity decreased only at later stages of hypokinesia. The changes in cytoplasmic NAD-MDH, NADP-ICDH and NADP-MDH were less expressed. On day 25 of the recovery period the activity of NAD-ICDH and NADP-ICDH was significantly higher than in the controls, that of mitochondrial NAD-MDH returned to the normal, and the activity of SDH and alpha-KGDH remained noticeably lowered.
