Daily Variations in Tissue Mitoses, Blood Eosinophils and Rectal Temperatures of Rats

Abstract
Characteristics of 24-hr. rhythms in rectal temp., in number of eosinophils, and in number of mitoses are descr. for male Line 3-Black rats. At the times of the daily high in rectal temp. and of the daily low in number of eosinophils, mitoses were also at a low in several different tissues: in the epidermis of the ear lobe as well as in the retromolar epithelium and in the connective tissue of the periodontal membrane.
