Streptococcic Meningitis

Effects of immunopotentiating agents on alveolar macrophage properties

“…This apparent influx of lung macrophages continued during the first week of life and stopped by 4 weeks after birth, a time at which the total AM number was identical to that of adults. During the same early period of life, a progressive maturation of rabbit AM was described, including morphological differentiation [9] and increased production of superoxide [10]. Similar results were obtained in the porcine species in which AM gradually appear during the first week of life [6].…”

“…Several experiments indicate that AM population appears just before or shortly after birth: by lung washing at sequential times during animal development, the total number of rabbit AM recovered was found to increase markedly before birth [9]. This apparent influx of lung macrophages continued during the first week of life and stopped by 4 weeks after birth, a time at which the total AM number was identical to that of adults.…”
