ABSTRACT
Background:
Although the hamster model of elastase induced emphysema is well characterized, the rat model has received less attention.Aim:
To evaluate the effect of a single intratracheal elastase dose on lung pathological changes of Sprague-Dawley rats. Material andmethods:
Rats were injected with a single intratracheal elastase dose of 28 U/100 g body weight or saline and studied 7, 15, 30 and 365 days after injection.Results:
Forty percent of rats died in the first 48 hours after injection, six were sacrificed at 7 days, 6 at 15 days, 7 at 30 days and 12 at 365 days. Progressive centroacinar emphysema was found from day 7 after elastase, with a persistent inflammatory reaction in the vicinity of emphysematous areas.Conclusions:
Present findings differ from the panacinar emphysema described in the hamster using a similar elastase dose
