[Stereomorphological relationship between colonic adenomas and peri-adenomatous mucosa in scanning electron microscopy. Histogenetic correlations].

Using scanning electron microscopy (SEM), then light microscopy, the authors have studied 25 colonic adenomas, 5 specimens of peri-adenomatous mucosa and 9 specimens of normal colonic mucosa. Comparison between SEM features and histological characteristics has shown that each of the three histological entities had an specific surface architecture. Comparative analysis of the different aspects observed at SEM has shown a close architectural relationship between the adenomas and the adjacent mucosa, and suggests the hypothesis that adenomatous polyps are formed by invagination of the surface epithelium which has a well-known capacity of proliferation.

Modifications of collagens in the course of inflammatory tracheal stenoses.

A comparison was made between the biochemical and histological properties of collagens contained in samples of normal tracheas obtained at autopsy or of stenosed tracheas obtained during surgery. The amounts of total collagen solubilized by pepsin was increased seven times in the pathological samples, and the proportion of cartilage type II collagen decreased by about one half, being replaced by type I collagen, whose ratio was increased five times. Microscopic studies confirmed that cartilage underwent a degenerative process and was progressively infiltrated by fibrils of interstitial collagen.
