The proportions of gland, muscle and cartilage were measured in the named bronchi of 43 byssinotics, and compared with the proportions in normal subjects and chronic bronchitics. The smoking habits and symptomatology of the byssinotics were also investigated. In the byssinotics the proportions of gland, muscle and cartilage were higher than in the normal, non-smoking subject at all levels in th...

The environment and health of a working population exposed simultaneously to jute and hemp were studied. Classical symptoms of byssinosis were not present but 21 workers (7%) complained of atypical tightness of the chest. The prevalence of chronic bronchitis among the exposed workers was statistically significant in comparison with controls. Effects of dust concentrations, age and duration of e...

A disabling chest disease characterized by bronchospasm (" byssinosis ") has, for many years, been recognized as affecting the workers in cotton blow rooms and card rooms (Collis, 1909), and has been attributed to inhalation of the airborne dust round the machines. It remains a serious industrial hazard in spite of measures which have been taken to reduce the dust, such as the improvement of ve...

There is general agreement that byssinosis is associated with the inhalation of cotton dust. Good descriptions of the disease have been given by the Home Office Departmental Committee on Dust in Card Rooms in their report (1932), by Prausnitz (1936), and by Schilling (1950). An extensive and complete review of the literature on cotton dust in relation to affections of the respiratory tract has ...

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...

Cotton dust samples from Cotton Incorporated were investigated by X-ray fluorescence and proximate analysis methods. These dust samples are known as "standard cotton dust" and have been used by many researchers investigating the causative agent(s) and physiological mechanisms of byssinosis. Silicon, calcium, potassium, and aluminum were present in relatively high concentrations (1-4%) in the du...

Vaskov, L. S. (1973). British Journal of Industrial Medicine, 30, 3741. Use of radioisotopes in the study of textile workers with byssinosis and chronic lung damage. A radioisotope method of measuring separately the circulation times for the pulmonary artery and pulmonary veins is described. Combined with pulmonary scintigraphy this method has been used to invesigate textile workers with lung c...
