Relationship between the activity of serum lactate dehydrogenase(LDH) and serum vitamin C in Japanese men and women in their middle and old age / 日本農村医学会雑誌

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.<BR>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.<BR>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.
