Ventilatory responses of normal subjects to flax dust inhalation: the protective effect of autoclaving the flax.

Ventilatory impairment from pre-harvest retted flax.

A new method of retting flax recently developed to suit the United Kingdom climate has allowed the reintroduction of flax growing to this country. The weed killer glyphosate is sprayed on the crop which then rets before harvesting six weeks later. The acute bronchoconstrictor responses of 11 normal subjects to dust from dew retted and from pre-harvest retted flaxes were compared in a double bli...

Branchial challenge of normal subjects with the endotoxin of Enterobacter agglomerans isolated from cotton dust.

Endotoxin produced by a culture of Enterobacter agglomerans isolated from cotton dust was inhaled by 12 normal subjects. No significant airway constriction was obtained in doses equivalent to those experienced in a workshift in a dusty mill. There was a statistically significant difference between this result and the bronchoconstriction that had occurred after flax dust inhalation in the same s...

Changes in Ventilatory Capacity in a Group of Flax Workers in Northern Ireland.

One-second forced expiratory volume (F.E.V.1.0) and forced vital capacity (F.V.C.) were measured before starting work in five flax hacklers with symptoms of grade II byssinosis and in five matched controls. Similar measurements were taken in each group at the end of the day shift. A significant (P < 0 05) decline in F.E.V.1.0 was observed in the hacklers during the day on Monday, Tuesday, Wedne...

Pharmacological prevention of acute ventilatory capacity reduction in flax dust exposure.

Respiratory response in simultaneous exposure to flax and hemp dust.

Zu§kin, E., and Valic, F. (1973). British Journal of Industrial Medicine, 30, 375-380. Respiratory response in simultaneous exposure to flax and hemp dust. The effect of exposure to high concentrations of mixtures of hemp and flax dust was studied in 124 workers in two textiie mills (mill A: 65-70% hemp and the rest flax, mean dust concentration 13 9 mg/m3; and mill B: about 35% hemp and the re...
