The influence of intravenous injections of Ukrain (1mg/kg) on the oxygen tension (р0₂) in muscle, the oxygen saturation rate and oxygen utilization rate as well as on the respiration and oxidative phosphorylation indices of the liver mitochondria in mice with melanoma B-16 was studied by polarographic method. Ukrain was shown to improve the oxygen delivery to the muscular tissue and to decrease a destructive effect of the malignant process on liver bioenergetics. The respiration rate of mitochondria during phosphorylation of exogenous ADP and the respiratory control coefficient were higher in the treated mice as compared to the untreated tumor-bearing animals. The drug significantly inhibited the growth of the primary tumor and its metastasis in lungs.

Key Words: Ukrain, oxygen tension, mitochondria respiration, metastasis.
