Further evaluation of a possible relationship between vitamin K deficiency and liver cytochrome oxidase or succinic dehydrogenase was performed. Although results indicate that the liver cytochrome oxidase activity is increased in rats fed a vitamin K-deficient diet (Johnson-type), a direct relationship of enzyme activity to vitamin K intake does not appear to be evident. A similar conclusion is indicated for liver succinic dehydrogenase. Other factors in the diet appear to play a greater role in cytochrome oxidase activity than does vitamin K. Erythrocyte transketolase activity in the rat was found to be related to the dietary intake of thiamine. The addition of sorbitol or the use of high levels of fat in the diet retarded the drop in RBC transketolase that resulted from the feeding of a thiamine-deficient diet. (auth)
