[IMPACT OF PLACENTA EXTRACT ON REGENERATION OF SKIN AFTER COLD TRAUMA].

In experiment on animals, in which the cold trauma was simulated, the systemic inflammatory reactions indices­level of С­reactive protein, аctive products of thiobarbituric acid the blood serum, erythrocyte sedimentation rate (ESR), leukocyte blood formula (LBF) while injection of placenta extract ­ were studied. C­reactive protein level lowering in 1.3 times on the 14­th day of experiment, reduction of ESR in 1.6 times on the 7­th and 14­th day, LBF normalization on the 7­th day, lowering of the аctive products of thiobarbituric acid level in 1.3 times on the 7, 9­th and 14­th day of observation were noted. On the 21­st day all the indices came back to norm.

[Lipid peroxidation in liver tissue of newborn and adult pigs under various cooling conditions]. / Intensivnost' peroksidnogo okisleniya lipidov v pecheni novorozhdennykh i polovozrelykh svinel pri razlichnykh ucloviiakh okhlazhdeniia

The paper is devoted to the investigation of the lipid peroxidation level according to measurements of the accumulation level of malon dialdehyde in fragments of the liver tissue of newborn and adult pigs, depending on the cooling rate and cryoprotectants used. The conclusion has been made on the basis of the data obtained. That the lipid peroxidation level in the liver tissue fragments is decreased with the increase of cooling rates. That is activated the least of all with the use of average cooling rate (100 degrees C/min) with dimethylsulphoxide (DMSO) as cryoprotectant in concentrations of 10, 20% and rapid cooling rate (80,000 degrees C/min) with polyethylenglycol-1500 (PEG-1500) and DMSO in analogous concentrations. These cryopreservation data have shown the lowest of the lipid peroxidation level in the liver tissue fragments when comparing one with native tissue (before freezing).
