title: [Superoxide dismutase activity in the broncho-alveolar lavage fluid in late asthmatic response model in guinea pigs].
abstract: In order to investigate the mechanism of the late asthmatic responses (LAR), LAR model in guinea pigs was made by inhalation of a large quantity of egg albumin antigen. Serial changes of inflammatory cells and superoxide dismutase activities in broncho-alveolar lavage fluids obtained from these animals were observed. In this model, increase in inflammatory cells, such as neutrophils, was observed in the broncho-alveolar lavage fluid during the late asthmatic responses of the attack and superoxide dismutase activity increased in the broncho-alveolar lavage fluid in parallel with the increase in inflammatory cells. These results suggest that change in superoxide dismutase activity in the broncho-alveolar lavage fluid may be involved in the onset of the late asthmatic responses.
