Abstract
The effects of the serum vitamin C levels on the activity and isozyme pattern of serum lactate dehydrogenase (LDH) in males and females in their middle and old age were examined.
There was no siginificant correlation among the total serum, LDH activity and serum vitamin C levels in the 87 male and 83 female ranging from 45 to 84 years of age. However, high inverse correlations were found among the percentage of LDH-4 and LDH-5 and serum vitamin C levels all of age groups (45-59 years of age group, 60-69 years of age group and over 70 years of age group) of males and females.
These results suggest that the percentage of LDH-4 and LDH-5 are influenced by the vitamin C intake in males and females in their middle and old age.
