Abstract
Whole body gamma irradiation was applied to the rats from CobaltGO source in dose of -1000 R, and its effects on the LDH isoenzyme pattern and its activities in incisor pulp ;at various intervals after irradiation were investigated.
This investigation established the followings:
1. At 72 hours postirradiation show a LDH isoenzyme pattern with strong LDH-1 and LDH-4 bands, ie, an enzyme capable of cooperation with both aerobic and anaerobic metabolic processes.
2. It demonstrated that total LDH activity at 24 hours postirradiation was much lower than the non irradiated, while at 72 hours postirradiation was nearly close to it.
