Effect of 2 Weeks Naringin Application on Neurological Function and Neurogenesis After Brain Ischemia-Reperfusion in...

Area of Science:

• Neuroscience
• Pharmacology
• Endocrinology

Background:

• Cerebral ischemia-reperfusion (I/R) injury can lead to neurological deficits.
• Ovariectomy in female rats can alter brain function and potentially exacerbate I/R effects.
• Naringin, a flavonoid, has shown potential neuroprotective properties.

Purpose of the Study:

• To investigate the effects of 2-week naringin supplementation on neurological scores and neurogenesis.
• To assess the impact of I/R injury in ovariectomized female rats.
• To determine if naringin can mitigate neurological deficits and improve neurogenesis markers post-I/R.

Main Methods:

• Establishment of an ovariectomized rat model with cerebral I/R.
• Groups included control, sham I/R, I/R, I/R with vehicle, and I/R with naringin treatment.
• Neurological scoring was performed on days 1, 7, and 14 post-surgery; hippocampus and frontal cortex protein levels (calbindin, alpha/beta-tubulin, Neu-N) were analyzed.

Main Results:

• Cerebral I/R significantly increased neurological scores and reduced calbindin, alpha/beta-tubulin, and Neu-N levels in the hippocampus and frontal cortex.
• Two weeks of naringin supplementation significantly suppressed the increase in neurological scores, with effects becoming more pronounced by the second week.
• Naringin treatment notably improved the levels of neurogenesis markers in the affected brain regions.

Conclusions:

• Naringin supplementation demonstrates significant neuroprotective effects against cerebral I/R injury in ovariectomized female rats.
• The treatment improved motor functions and enhanced neurogenesis in the frontal cortex and hippocampus.
• Naringin holds promise as a therapeutic agent for managing neurological impairments following ischemic events in this model.
