Abstract
Summary
Fertile eggs from normal and genetically-dystrophic chickens were placed in an environment chamber on day 19 of development. The atmosphere contained 45% oxygen until the chicks hatched, at which time it was raised to 70%. The chickens were maintained in the high oxygen atmosphere until 6 weeks of age when they were sacrificed for histological examination. The breast muscles of oxygen-treated dystrophic chickens underwent only minimal cytological changes when compared to both untreated normal and dystrophic controls. Breast muscles of oxygen-treated normal chickens showed no changes. It is concluded that continuous treatment in a high oxygen environment retards the progress of the hereditary myopathy.
