title: The biochemical and pathological changes produced by the intratracheal instillation of certain components of zinc-hexachloroethane smoke.
abstract: Zinc chloride which is formed by igniting a mixture of zinc oxide and hexachloroethane in the production of white smokes has been shown to produce oedema when given to rats as a single instillation. The oedematous reaction, as assessed by histopathology and measurements of alveolar surface protein in lavage fluid, is variable, dose-dependent, and maximal at 3 days but at sub-lethal doses it regresses after 7 days. The parent compound, zinc oxide, does not produce these effects. In some animals there is evidence of a fibrogenic response at 7 days post-exposure although it is currently unknown whether or not this effect is progressive.
