The paper was to investigate the character of malonic dialdehyde content shifts in the vitreous body under the effect of potassium fenosane, oxipyridinchlorhydrate (OPChH), superoxidedismutase, sodium diethylditiokarbamat (DDTK), forming complex with copper under the experimental hemorrhage. Decrease in LPO speed shown after potassium fenosane administration was considerable under retrobulbar administration. More pronounced inhibition of LPO reaction under the hemorrhage was noted in combination of antioxidants with superoxidedysmutase.
