Abstract

An attempt was made recently to compare and to contrast the changes in the leukocyte counts in patients with bronchopneumonia and with suppuration. It was noted that in the cases of bronchopneumonia the monocytes in the circulating blood increased in the early stages of the disease to a point definitely above normal, and that later the number1 again became normal.

The object of the present work was to determine whether similar changes occurred in patients with lobar pneumonia and, by comparing the changing blood picture with the clinical course of the disease, to determine whether any deductions could be drawn regarding the function of these cells.

Daily total leukocyte counts were performed on the patients, the blood being obtained by pricking the lobe of the ear. Cover-glass films of the blood were made at the same time and stained. The differential blood count was performed under the oil immersion lens.
