Overview

Excerpt from Catarrhal Diseases of the Nasal and Respiratory Organs The literal meaning of the word catarrh is to flow down. But the significance of the term in medicine is much broader than this. The inflammatory attack upon the mucous membranes, which ushers in a catarrh, usually arrests, in the first place, the moist secretion uniformly found in a healthy condition of these membranes. Inspection also shows that the membrane becomes tumid, and its color is much redder than natural, and its sensibility under goes a perceptible change. The structure of mucous membranes is such that expansion occurs freely, hence the sense of pain is less than in tissues not as elastic; but we have the sensations of pressure, heat and itching. The first result of a catarrhal attack, as we have said, is a dryness of the mucous mem branes, still there may be much difficulty in breathing; a stuffed-up feeling, and a sense of something obstructing is felt which is the effect of the thickening of the membranes. In consequence of this thickening the sense of smell is dulled and perhaps entirely lost. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
