title: [Regional blood flow distribution in waking rats under elevated external temperature].
abstract: The heart output (HO) was estimated by means of the 133 Xe clearance in the rat tail, the rat being placed either in a narrow hole or a spacious box. In the hole, the HO rose from 24 to 36 ml/(min.100 g), in the box the HO portions of skeletal muscles and bones were by 3.8 and 2.0 times lower; in the hole, their reduction was insignificant; the lung radioactivity rose from 4 to 20% (the hole) and to 42% (the box) which suggests a considerable increase in the blood flow through arterial-venous anastomoses.
