International journal of tissue reactions, 1991•europepmc.orgThis study was performed to determine whether temporal variations could exist in
polymorphonuclear neutrophil (PMN) migration induced by LPS or BCG in mice. LPS-and
BCG-impregnated cell traps were implanted at 6 different times of the day and removed after
480 min. The PMN number per square unit (mm2) was counted and the results were
expressed as means+/-SE in 8-10 mice. The results showed that nycthemeral variations
occurred in both LPS-and BCG-induced PMN migration. Between 5.00 and 9.00 ha …

This study was performed to determine whether temporal variations could exist in polymorphonuclear neutrophil (PMN) migration induced by LPS or BCG in mice. LPS-and BCG-impregnated cell traps were implanted at 6 different times of the day and removed after 480 min. The PMN number per square unit (mm2) was counted and the results were expressed as means+/-SE in 8-10 mice. The results showed that nycthemeral variations occurred in both LPS-and BCG-induced PMN migration. Between 5.00 and 9.00 ha maximum value of 4210+/-270 and 1920+/-486 PMN/mm2 were obtained with BCG and LPS respectively; at 17.00 ha minimum value of 1300+/-270 with BCG and 396+/-127 PMN/mm2 with LPS were observed. There was no significant nycthemeral variation in saline-induced PMN migration.
