Histopathological studies on experimentally induced pulmonary adenomatosis in guinea-pig lungs. 1975

C Torikata, and H Takeuchi, and H Yamaguchi, and K Kageyama

The main purpose of our experimental series was to induce, in experimental animals, diffuse pulmonary fibrosis resembling that in human lungs. In the lungs of guinea-pigs injected with a soluble immune complex and continuously exposed to a 40-60 per cent oxygen-rich atmosphere, diffuse pulmonary fibrosis occurred in many cases in the course of 2 to 3 months after the injection. After the 100th experimental day, multiple foci of pulmonary adenomatosis occurred. The morphology was similar to that of Jaagsiekte. Electron microscopic observations revealed that these hyperplastic cells originated from type II pneumoncytes.

UI	MeSH Term	Description	Entries
D006965	Hyperplasia	An increase in the number of cells in a tissue or organ without tumor formation. It differs from HYPERTROPHY, which is an increase in bulk without an increase in the number of cells.	Hyperplasias
D007106	Immune Sera	Serum that contains antibodies. It is obtained from an animal that has been immunized either by ANTIGEN injection or infection with microorganisms containing the antigen.	Antisera,Immune Serums,Sera, Immune,Serums, Immune

D010100	Oxygen	An element with atomic symbol O, atomic number 8, and atomic weight [15.99903; 15.99977]. It is the most abundant element on earth and essential for respiration.	Dioxygen,Oxygen-16,Oxygen 16
D011650	Pulmonary Alveoli	Small polyhedral outpouchings along the walls of the alveolar sacs, alveolar ducts and terminal bronchioles through the walls of which gas exchange between alveolar air and pulmonary capillary blood takes place.	Alveoli, Pulmonary,Alveolus, Pulmonary,Pulmonary Alveolus
D011658	Pulmonary Fibrosis	A process in which normal lung tissues are progressively replaced by FIBROBLASTS and COLLAGEN causing an irreversible loss of the ability to transfer oxygen into the bloodstream via PULMONARY ALVEOLI. Patients show progressive DYSPNEA finally resulting in death.

D002282	Adenocarcinoma, Bronchiolo-Alveolar	A carcinoma derived from epithelium of terminal bronchioles, in which the neoplastic tissue extends along the alveolar walls and grows in small masses within the alveoli. Involvement may be uniformly diffuse and massive, or nodular, or lobular. The neoplastic cells are cuboidal or columnar and form papillary structures. Mucin may be demonstrated in some of the cells and in the material in the alveoli, which also includes denuded cells. Metastases in regional lymph nodes, and in even more distant sites, are known to occur, but are infrequent.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
