• Authors: K.H. Kilburn, A.R. Dowell
• Published: Archives of Internal Medicine, Volume 127 No5. May 1971.

In plain English

This article was a short introduction by the authors to a journal symposium on pollution and lung biochemistry, published in Archives of Internal Medicine in May 1971. It was not a study and reported no new data, subjects or measurements. The authors described emphysema and pulmonary fibrosis as chronic lung diseases that were increasing in prevalence. They noted that a quarter of the symposium papers concerned the lung's connective tissue. They suggested that the morphometric methods used by Gil might detect changes in alveolar connective tissue more sensitively than the amino acid analyses proposed by Pickrell and Shafer. Asbestos appeared only once, in a passing statement that particles of silica, asbestos and beryllium stimulate fibrosis in human and animal lungs. No asbestos fiber type was named and no asbestos research was described. The authors wrote that a model for the growth of connective tissue would be useful. A closing passage began by saying that something was impossible concerning human alveolar disease, judged from the present efforts, but most of its wording could not be read in the scan.

We wrote this plain-English summary from the full article with the help of AI, and a second AI model checked each sentence against the article. It is not the authors' wording; the abstract and the article are their own account.

What the study did and found

• Design: Introduction to a journal symposium (commentary); no original research
• Who was studied: None; no people, animals or samples were studied
• Exposure: No exposure was studied. Asbestos was mentioned once, together with silica and beryllium, as particles that stimulate lung fibrosis. No fiber type was named.
• Main results:
  • No study findings. The authors wrote that emphysema and pulmonary fibrosis are chronic lung diseases increasing in prevalence.
  • The authors noted that a quarter of the papers in the symposium concerned connective tissue.
  • The authors suggested that the morphometric methods used by Gil may be more sensitive for changes in alveolar connective tissue than the biochemical amino acid analyses proposed by Pickrell and Shafer.
  • The authors stated, as background, that particles of silica, asbestos and beryllium stimulate fibrosis in human and animal lungs.
  • The authors referred to symposium work by Stephens et al reporting changes in collagen after nitrogen dioxide exposure that resemble the changes of aging.
• The authors' conclusion: The authors wrote that a model for proliferation of connective tissue, as useful as the papain model for loss of tissue, would be useful. A closing passage says something was impossible concerning human alveolar disease, judged from the present efforts. Its exact wording is mostly illegible in the scan.
