متن کاملReaction of mineral dusts with primary lung fibroblast cultures.
The complex metabolism of rabbit lung fibroblast cultures maintained over 24 days in vitro and their interaction with the fibrogenic group of asbestos minerals is reviewed. The differential effects of nine dusts given as a single dose to 3-day-old fibroblast cultures which were then analyzed for DNA, protein and cell mat hydroxyproline after 3 weeks are discussed. A comparison is made of the ab...
