| Outline of Final Research Achievements |
Although both lesions had lymphoplasmacyte infiltrated lesion, lung lesions of IgG4-related disease was characterized by active fibrosis with eosinophilic infiltration within lymphatic stroma itself with obstructive vasculitis, whereas lung lesion of idiopathic multicentric Castleman's disease was marked lymphoplasmacyte proliferating lesions mainly in the alveolar area adjacent to lymphatic stroma and sometimes conspicuous cyst formation. These clinicopathological features may help differentiate them and influence their prognoses.
RA lung model in D1CC mice is very similar to RA lung in humans with inflammatory cells infiltration and alveolitis as lymphangiitic distribution and would be valuable model for investing general pathophysiology of chronic interstitial pneumonias in humans. H2 treatment protected the lung damage with reduction of the increased levels of serum SP-D, CT image density as well as histological changes, thus would be valuable for protection against RA induced lung.
