THE EFFECT OF ADEMOL ON THE DNA FRAGMENTATION OF CEREBRAL CORTEX CELLS IN RATS WITH EXPERIMENTAL TRAUMATIC BRAIN...

Area of Science:

• Neuroscience
• Cell Biology
• Pharmacology

Background:

• Traumatic brain injury (TBI) can lead to significant cellular damage, including apoptosis.
• Deoxyribonucleic acid (DNA) fragmentation is a key indicator of apoptosis in brain cells.
• Understanding therapeutic interventions to mitigate TBI-induced cell death is crucial.

Purpose of the Study:

• To evaluate the efficacy of Ademol in preventing DNA fragmentation in cerebral cortex cells following TBI in a rat model.
• To compare the anti-apoptotic effects of Ademol with standard saline and amantadine sulfate treatments.

Main Methods:

• A severe TBI model was induced in male rats using an air pistol.
• Rats received intravenous Ademol (2 mg/kg, twice daily for 8 days), 0.9% NaCl, or amantadine sulfate (5 mg/kg).
• Cerebral cortex DNA fragmentation was quantified using flow cytometry on day 8 post-TBI.

Main Results:

• TBI in rats resulted in increased DNA fragmentation in cerebral cortex cells by day 8.
• Ademol treatment significantly reduced DNA fragmentation compared to 0.9% NaCl (46.2% reduction).
• Ademol demonstrated a superior anti-apoptotic effect compared to amantadine sulfate (27.2% reduction; p<0.05).

Conclusions:

• Ademol exhibits significant anti-apoptotic properties in the context of post-traumatic brain injury.
• Ademol therapy is more effective than amantadine sulfate in mitigating TBI-induced neuronal DNA fragmentation.
• These findings suggest Ademol's potential as a therapeutic agent for managing TBI.
