[Mucoviscidosis (cystic fibrosis), a disease of an unclear structure until recently]

Cystic fibrosis (mucoviscidosis) is described in a review article. The cause of this common lethal hereditary disease of white people is hitherto unknown. The early dead of patients with cystic fibrosis, a genetic paradoxon, a lot of hypotheses and very high demands in treatment should challenge more scientists for research. There are added some short notes about the authors work in history of cystic fibrosis.
