title: Monthly changes in the effect of BCG on the migration of polymorphonuclear leucocytes.
abstract: Monthly changes in the migration of polymorphonuclear leucocytes (PMN) produced by subcutaneous implantation of BCG-impregnated rayone-made disks was examined over a period of 15 months. In experiments carried out at 90h00, the highest PMN count of 40.2 +/- 8.4 PMN/10,000 micrometers2 10,000 micrometers2 was obtained in April. Mechanisms that could explain the circannual variation are suggested.
