Evans, Elizabeth and Nicholls, P. J. (1974).British Journal of Industrial Medicine,31, 28-30. Histamine release by Western red cedar(Thuja plicata)from lung tissue in vitro. Various respiratory symptoms have previously been observed in workers exposed to dust from Western red cedar (Thuja plicata). Although an allergic basis for these effects has been proposed, the possibility that the dust may contain a pharmacologically active agent was investigated. Aqueous extracts of two samples of red… Expand

Western Red Cedar (Thuja plicata) and Other Wood Dusts
TLDR
Occupational asthma caused by western red cedar (WRC) has been studied extensively because it affects a vast number of workers in the primary industries of the West coast of North America and in countries where red c Cedar is exported. Expand
Induction of histamine release in vitro from rat peritoneal mast cells by extracts of grain dust.
TLDR
The ability of extracts of grain dust and wheat to induce Histamine release from rat peritoneal cells was investigated and the agent did not appear to be a lectin because histamine release was not enhanced by passive sensitization of mast cells with IgE. Expand

Respiratory diseases in wood workers.
TLDR
Exposure to wood dust or to some bronchoreactive substances linked with wood working can induce chronic obstructive lung disease (COLD). Expand
Occupational vocal cord dysfunction due to exposure to wood dust and xerographic toner.
TLDR
The differences in the clinical presentation of the patients described relative to the reported cases suggest that more than one pathophysiological mechanism may be implicated in the genesis of this entity. Expand
Health Hazards Associated with Extractives
The story told by the dead king, of being murdered by his brother using hebona juice, leaves an indelible picture in the mind. Perhaps the reason for this is that the story was so well and succinctlyExpand
Respiratory health effects from occupational exposure to wood dusts.
TLDR
The clinical and epidemiologic literature is reviewed and the specific woods (with botanical names) and their respiratory disease correlates are identified, including pulmonary function declines, chronic and acute symptoms, and impaired mucociliary transport. Expand
Occupational asthma. Update on a proliferating problem.
TLDR
The list of agents known or suspected to cause occupational asthma is increasing almost daily and management of occupational asthma must be approached on an individual basis and at an industry-wide level. Expand

HISTAMINE RELEASE BY COMPOUND 48/80 AND TEXTILE DUSTS FROM LUNG TISSUE IN VITRO
Abstract Extracts of cotton, flax and hemp dusts, and of the bracts of the cotton boll do not release histamine from guinea pig, rat, cat, sheep and pig lung tissue in vitro. They do, however,Expand
Occupational asthma and rhinitis due to Western red cedar (Thuja plicate), with special reference to bronchial reactivity
TLDR
Six cases of asthma and four of rhinitis are described in some detail; the onset of symptoms some hours after exposure, the nocturnal predominance of symptoms, and their persistence for days or weeks after cessation of exposure may make diagnosis difficult if the occupational hazard is not appreciated. Expand
Bronchial reactions to western red cedar (Thuja plicata).
TLDR
The clinical features and the results of investigations of three patients with asthma due to western red cedar are described and an attempt was made to identify the responsible allergen in the red c Cedar extract. Expand

TLDR
It is suggested that in rats the histamine-releasing mechanism of the antigen-antibody reaction in anaphylaxis is very similar to that of compound 48/80. Expand
COEXISTENCE OF ENERGY DEPENDENT AND NONDEPENDENT PROCESSES IN HISTAMINE RELEASE MECHANISM OF COMPOUND 48/80 AND SINOMENINE: EXPERIMENTS ON CHOPPED SKIN FROM VARIOUS ANIMAL SPECIES
TLDR
In the present study, in vitro histamine release by compound 48/80 as well as sinomenine from chopped skin of different animal species including guinea pig was compared under aerobic and anaerobic conditions, and it was found that the release of histamine in all these species consisted of two different types of release: the one which is dependent on energy-yielding processes and the other which does not depend on the processes.

Silicosis, asbestosis and pneumoconiosis of coal miners and coal trimmers have been described in this issue and the author has been invited to deal with the remaining dust diseases of the lungs. Expand
Evidence for enzymatic histamine release from isolated rat mast cells.
TLDR
The influence of pH, temperature and enzyme inhibitors indicates that the histamine-releasing action of compound 48 80 has been studied on mast cells isolated from rat peritoneal cavity, and on mesentery cells in situ. Expand
A method for the fluorometric assay of histamine in tissues.
TLDR
Gross dissection of brain showed no marked localization of brain histamine and a sensitive and specific fluorometric method for the estimation of histamine in tissues was described. Expand

TLDR
A simplified procedure for testing respirator sorbents for break-through when used against specific toxic gases is described, and Comparative tests with SO2 show good agreement with the conductivity method. Expand
