Change in Tail Skin Temperature during Exposure to Various Ambient Temperatures in Chronic Spinal Rats

Abstracts: Change in tail skin temperature during exposure to various ambient temper-atures was studied in chronic spinal rats. Lower end of the cervical cord (C-8) was transected by aspiration under pentobarbital anesthesia, and then the rats were reared in heart rate (HR) and ambient temperature (Ta) were recorded simultaneously in three groups Chronic spinal rats were exposed to sequential and reciprocal change of Ta ranging from dT, or excess temperature of the tail skin (dT=Ttail-Ta). Mean regression coefficient by conduction, convection and radiation depends on dT, heat loss from the tail may be progressively reduced with an increase of days after spinalization
