title: [The role of the oscillation of the tail vessels in unanesthetized rats in regulating the blood flow during heat exposure].
abstract: Studies of the changes in the rat tail blood vessels in heating shows a considerable increase in slow oscillation frequency, apart from the rheographic index elevation. The hyperthermic effect became considerably lesser in elimination of these oscillations with ganglio- or adrenoblocking agents. The mechanism of hyperemia in heating associated with modulation of mechanic contractions of vascular smooth muscles, are discussed.
