The state of the receptors of the hindlimb in dogs during the development of a collateral circulation and of radiation sickness

Abstract

The authors studied the effect of irradiation (450 r) on the condition of the receptors of the posterior limb of the dog in which a collateral circulation developed after resection of the femoral artery. The change of the afferent impulsation in the operated limb was shown by: a) Thelability of the reflexes observed durin the first 4–6 days of development of collaterals in radiation sickness: b) the increase of the reflexes corresponding to the further development of the collateral circulation, and, c) depression of the reflexes beginning with the 11th–12th day from the onset of acute radiation sickness with the continuation of the process of development of collaterals.
