title: Pulmonary fibrosis of low calcium diet fed guinea pigs induced by the administration of a soluble immune complex.
abstract: Feeding animals a low calcium diet leads to lymphangiectasis of peribronchial lymphatic vessels, sometimes followed by overflow of lymphatic fluid into the surrounding tissue. Adding a soluble immune complex (SIC) to the diet, the peculiar diffuse interstitial pneumonia and finally pulmonary fibrosis were noted. Small honey-combed structures and sometimes histologic accommodation of epithelial lining cells were observed. Sometimes accumulation of leucocytes within honey-combed structures was seen.
