Hematological effects of radiant heat-induced whole body hyperthermia on dogs.

Abstract

The effects on hematological parameters of radiant heat-induced whole body hyperthermia (WBH) at 40.5 degrees C and 41.8 degrees C were determined in 6 normal dogs. Complete blood counts determined prior to WBH, immediately post WBH plateau, and at 1, 2, 7, and 14 days posttreatment did not change significantly following WBH at 40.5 degrees C or 41.8 degrees C. Similarly, no significant changes were detected in platelet counts measured following 40.5 degrees C WBH. In contrast, platelet counts 11 days following 41.8 degrees C WBH increased significantly (P < 0.05) consistent with the hypothesis of induction of putative WBH-induced platelet stimulating factors.
