Occupational dermatitis from soldering flux.
The aim of this study was to determine the specific agent responsible for eczema on the forearms of 2 electronic assemblers who cleaned out a flux-spraying unit once a week. Soldering flux can be a source of skin irritation as well as allergy. Patch test with dried flux residue (as is) and rosin in dilution series of 20%, 10%, and 1% in olive oil was performed. Readings were taken on day 2 and ...

copper as a material for electric cables. A previous survey of respiratory complaints after the use of this particular flux had failed to show any objective change in lung function, and the present cases are the first to be reported. Both subjects have been investigated by means of serial spirometry, peak flow rates, and body plethysmography following inhalation of small amounts of flux fumes; ...

متن کاملStudies on Enzyme Action
The hydrolyzing actions of various preparations of the adult eel were studied on ten esters in the usual way. The results are presented in the form of curves for the relative actions and in a table for the absolute actions obtained in one complete experiment. The separation of the enzyme material in some cases into an active portion and a co-enzyme, the mixture showing greater actions on some e...
متن کاملStudies on Ferment Action
1. Erythrocytes have definite lipoidal constituents and lipoidal combinations peculiar to the species. 2. Certain lipoids and lipoidal combinations act as specific antigens. 3. The increase in serum lipase which occurs upon immunization of animals to foreign red cells is, at least in part, specific. 4. This specific lipase plays, no doubt, an important part in specific serum hemolyses.
