Abstract
Variations in the counts of circulating basophile leucocytes in 225 subjects were studied. The results obtained are as follows: 1) The counts (per mm3) show a gradual rise with growth, from infancy to adolescence, and maintain a fair constancy in adults. 2) No significant sex difference was found in the peripheral basophile counts. 3) A definite diurnal variation in the counts exists, which is lowest in the morning and highest in the evening. 4) The counts are altered in different phases of the menstrual cycle. 5) Pregnant women show lower counts than nonpregnant women. 6) Surgical trauma and a single electroconvulsive shock lowers the counts significantly but variations are not significant after meals and physical exercise. 7) Smokers have slightly higher counts than non-smokers. 8) A course of irradiation therapy lowers the counts significantly in patients with inoperable neoplastic diseases. 9) Counts show insignificant variation with alteration of blood glucose level. The results mentioned above are discussed.
