Studies on Lactate Dehydrogenase Isoenzymes in Human Gingiva

Part 3 The Patterns of Lactate Dehydrogenase Isoenzymes in Fetal Gingiva

Abstract

1. The supernatant fraction obtained from fetal and adult gingivae differed in the total LDH activity. The activity of LDH in adult gingiva increased about 4 fold over that of the fetus.
2. Five isoenzymes of LDH were isolated from fetal gingiva.
3. The percentage composition of activity of LDH1, 2, 3, 4 and 5 in fetal gingiva differed from that of adult.
