Respiratory changes in two groups of flax workers with different exposure pattern

Respiratory changes in two groups of flax workers with different exposure pattern.

Respiratory disability in ex-flax workers.

Acute respiratory effects occur in a high proportion of subjects exposed to textile dusts. The extent to which these lead to permanent respiratory symptoms and loss of lung function is unknown. A survey of random population samples was therefore conducted in ten towns in Northern Ireland in which flax processing had been a major source of employment. The MRC questionnaire on respiratory symptom...

Changes in the transcription pattern of flax cotyledons after inoculation with flax rust.

The rate of (32)P incorporation into RNA fractions of flax cotyledons (Linum usitatissimum L. var. Bison) was found to increase two- to three-fold by 48h after inoculation with flax rust [Melampsora lini (Pers.) Lev., race no. 3]. This was accompanied by a change in the nucleotide composition of the newly transcribed sodium chloride-soluble RNA fraction. A comparison of the nucleotide compositi...

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...

Mortality of flax workers.

A total of 2528 workers in flax mills in Northern Ireland were followed up for 16 years. Follow-up was 97% complete. Deaths were identified and date and cause ascertained. Expected deaths were calculated on the basis of age and sex specific rates for Northern Ireland. Both male and female workers had fewer deaths than expected, and mortality showed no clear relationship with type of work. There...
