The pharmacology of chymotrypsin administered by inhalation.

The ability of chymotrypsin to reach the limits of the bronchial tree has been studied in cats receiving the enzyme by inhalation as a very fine powder. For this purpose derivatives of chymotrypsin were used which had been labelled with a fluorescent molecule or with [(131)I]. Quantitative measurements of the absorption and distribution of inhaled chymotrypsin- [(131)I] revealed a rapid removal of radioactivity from the lungs over the first 24 hr. and corresponding excretion of labelled inorganic iodide in the urine. High levels of activity were not attained in the blood or thyroid. Subcutaneous administration of labelled enzyme led to more rapid accumulation of radioactivity in the blood and thyroid. Consideration of these and other results leads to the conclusion that, while some enzyme ascends the respiratory tract by ciliary movement of mucus, a substantial part is absorbed into the lungs and the [(131)I] subsequently detached from it.The changes in tidal air accompanying inhalation of labelled trypsin and chymotrypsin were followed in anaesthetized cats. Trypsin brings about a decrease in tidal air in distinctly lower doses than does chymotrypsin. Prior administration of mepyramine had an antagonistic effect, and it is suggested that the change in tidal air is essentially the result of bronchial spasm.

Local effects and mechanism of absorption of iron preparations administered intramuscularly.

An attempt has been made to correlate factors involved in the absorption of iron-polysaccharide complexes administered intramuscularly. Different complexes varied greatly in degree of retention in muscle and in diffusibility in agar; these two characteristics were not closely related. The local changes in the muscle produced by the iron complexes consisted of an acute inflammatory reaction at the site of injection, with degenerative changes. Subsequent regeneration was rapid and complete. The major proportion of the absorption occurred during the initial 72 hr. and appeared to be mediated partly by the inflammatory reaction evoked, with enhancement of lymphatic transport of the iron complex. Rapid fixation by tissue macrophages impeded absorption and, with some complexes, this factor may make much of the injection inaccessible.
