Abstract : A search was made for a hematological parameter that might indicate when acclimatization to cold occurred in mice. The formed elements of mouse peripheral blood tested were total white blood cells and the absolute numbers of polymorphonuclear leucocytes, monocytes, lymphocytes, stress lymphocytes and eosinophils. In addition the hematocrit, body weights, and adrenal gland weights were measured. No consistent changes between 21 and 2CC<< <C caged mice were observed with respect to the total WBC, PMN, stress lymphocytes, lymphocytes and monocytes. The eosinophils of the cold stressed animals were consistently lower than the 21C caged mice. The body weights of the cold exposed animals showed initial decreases but this was compensated and weight gain proceeded normally after five days post-exposure. The adrenal glands showed maximally increased weights at 24 hours post-exposure. The results of the experiment were unrewarding with respect to finding a parameter for cold acclimatization. (Author)
