title: Effect of cigarette smoke exposure on maturation of the antibody response in spleens of newborn mice.
abstract: Balb/c mice were exposed to smoke from Kentucky Reference IRI cigarettes within 24 hr after birth on a Prototype Mark II Walton Horizontal Smoke Exposure Machine for various periods of time up to 10 wk of age. There was no difference in the magnitude of the splenic plaque-forming cells (PFC) response in smoke-exposed and untreated control animals immunized with sheep red blood cells (SRBC) on sequential days up to day 9 postpartum. However, beginning at day 10 and for each subsequent time period assayed thereafter, there was a statistically significant reduction in the number of splenic PFC observed in the smoke-exposed animals. On day 10, the PFC response of smoke-exposed mice was reduced by 33%, on day 14, there was a 60% reduction, whereas animals exposed to smoke from 4-10 wk showed a 90% reduction of the splenic PFC response.
