Abstract: A combination aerosol container carrier and deceleration chamber carries an aerosol container interiorly of the deceleration chamber and by pulling out and, pivoting the aerosol container in its case, is changed to a dispensing configuration in such a manner that essential parts are not apt to be dropped and incorrect assembly is avoided even when the user is under stress or adverse environmental conditions. The dispenser provides for unitary doses of inhalable medicament, with uniform doses and very convenient administration.

Abstract: The susceptability of microorganisms to various antibiotics is determined by propagating microorganisms in the presence of different concentrations of the antibiotic in a plurality of test cells or chambers axially aligned on one element of a cylinder of plastic which cylinder has a concentric protective sleeve with apertures to match the test cups and indexing and orienting means to keep the sleeve and cylinder aligned. A series of concentrations of a particular antibiotic are prepackaged and stored dry in the test cells of a particular cylinder with various antibiotics in various cylinders which may be positioned in a storage rack for convenience in inoculation and incubation.

Abstract: Asthma is effectively treated by inhalation of powder dispensed from an aerosol suspension of powdered N,N-diethyl-4-methyl-1-piperazinecarboxamide pamoate, which is dispersed as a fine powder, essentially below 10 microns in particle size, which gives an improved ratio of absorption in the lungs as compared to systemic absorption.
