Observations on the pathogenesis of silicosis by means of the diffusion chamber technique.
An attempt has been made to determine whether the diffusion chamber technique can be used to decide the validity of the silica solubility theory of the pathogenesis of silicosis. Small chambers were constructed from membranes of a pore size which allowed free passage of colloidal silicic acid and tissue fluids but which prevented the entry of host cells and the exit of the larger silica particl...

A significant proportion of workers exposed to silica dust are at risk of developing tuberculosis (TB). The higher the International Labor Organization (ILO) category of silicosis, the greater the TB risk. Subtle radiographic presentations of TB may be the initial manifestation of TB, particularly in the absence of sputum identification of TB bacilli. A proposed TB x-ray-reading form in additio...
متن کاملAcute Silicosis
A QUARTER of the earth's crust is composed of silicon, so it is not surprising that the inhalation of dust has been recognised for centuries as a cause of shortness of breath in miners and stone operatives. In 1649 Dimerbrook (Collins, 1915) described chest rigidity associated with dyspncea in the granite workers of the Carpathians, who were themselves painfully aware of the occupational hazard...
متن کاملAn eruption of silicosis.
Although-or perhaps because-environmental health concerns affect every person on the planet, scientists often suffer a modern day Tower of Babel syndrome, using a diversity of terms in all different languages to describe the same ideas. So European, American, and international agencies have decided to collaborate on the development of a global multilingual environmental thesaurus to eliminate t...
