MECHANISM OF BRONCHOCONSTRICTION DURING INHALATION OF SULFUR DIOXIDE.
Inhalation of SO2 (4–6 ppm) for 10 min decreased airway conductance (increased airway resistance) in seven healthy subjects. Subcutaneous injection of atropine prevented this effect. In anesthetize...
Inhalation toxicities of some aldehydes.
The anatomical basis of the straub phenomenon.
TLDR
It was concluded that the phenomenon described by Straub (1911) was produced mainly by the action of the sacro-coccygeus dorsalis muscle, and that it was also necessary that the lumbo-sacral cord with its peripheral nervous outflow should be intact and that these functioning units should have an adequate circulation.
MICRO-METHOD FOR INTRAVENOUS INJECTION AND BLOOD SAMPLING.
Abstract The described methods have been found to be valuable in investigations into the body distribution and fate of pharmacological sub-stances and are herein reported for the beqefit of other
Kerosene smoke and atmospheric pollutants.
Mechanism of bronchoconstriction
TLDR
Rapidity of response and subsequent reversal suggests that changes in smooth muscle tone cause bronchoconstriction, as lower airway constriction occurred with upper airway exposure, and SO/sub 2/ acts like other stimuli producing bronchpresence.
Health Aspects of Bioaerosols
Bioaerosols have been defined as colloidal suspensions in air of liquid droplets or solid particles, containing, or having attached to them, one or more living organisms. These organisms include
Assessment of the Phagocytic Activity of the Macrophage System
TLDR
A technique for assessment of the phagocytic activity of the macrophage (reticulo-endothelial) system involving the introduction of a known quantity of particulate carbon into the circulation and the recording of its disappearance over a period of time is reported.
