[Metabolic enzymes in human nasal mucus under physiological and pathophysiological conditions of the mucous membrane (author's transl)].

In the human nasal mucus several enzymes of the intermediary metabolism are present. Due to secreted albumin the enzyme-levels are determined in different diseases of the upper respiratory tract. It is possible to differentiate viral rhinitis from bacterial or allergic or atrophic rhinitis by a significant increase of the activities of GOT, LDH and CPK.
