Abstract
1) When rabbits are fixed on animal board, their body temperature falls to a fixed level and shivering sets in. The fall of body temperature traces a fixed course and the critical body temperature for shivering shows little variation whenever the animals are non-anesthetized and in good condition.
2) When anesthetized rabbits are fixed, the fall of body temperature increases and the critical body temperature for shivering becomes lower in proportion to the amount of narcotics, Room temperature ranging from 5°C to 20°C did not have any marked effect on these phenomena in both anesthetized and non-anesthetized rabbits.
3) At onset of shivering, the following correlation formula consists between the blood pressure and the body temperature;
(P-a)ΔBT=b
Both “a” and “b” are constants, “P” representing the value of blood pressure, “ΔBT” expressing the value of falling degree below the normal body temperature.
