[The blood supply and oxygen balance of the different tissues of the extremities following experimental sympathectomy].

The experiments in dogs suggested an essential difference in terms of the rearrangement of regional blood circulation in the skin and muscles of the extremity after experimental sympathectomy. Ganglionectomy induced a reduction of general peripheral arterial resistance on the operated side, an increase in the skin tissue blood flow and its oxygenation rate, a deceleration of the process of biological oxidation reducing the capability of muscles to use blood oxygen and cutting down the maximum of oxidase cytochrome (a3) activity. There was no essential change in the regional acid-alkaline balance. The above changes were due to a disturbance of the neurotrophic sympathetic effect on tissues.
