One of the most consistent characteristics of cystic fibrosis is the abnormal handling of electrolytes by exocrine glands. The present study has examined the possibility that diminished respiratory energy formation is a primary biochemical error responsible for this abnormality. Using oxygen consumption of intact larval brine shrimp, quantitative differences have been observed from reaction of mixed mouth saliva between CF heterozygotes and CF homozygotes. In addition, information demonstrating a correlation between a biochemical abnormality and disease severity was observed. The differences observed in inhibition by saliva from both CF homozygotes and obligate heterozygotes may occur as the result of 1) interference with electron transfer from organic fuel molecules to molecular oxygen or 2) interference with the mechanism responsible for generating the biochemical reducing power necessary for multiple biosynthetic reactions.
