OBJECTIVE
The present study investigated the neuroprotective effects of chrysin (CRS) following global cerebral ischemia and reperfusion (I/R) in a C57BL/J6 mouse model.
METHODS
A total of 40 mice were equally divided into four groups: (1) sham-operated (SH = control), (2) global cerebral I/R (I/R), (3) CRS, and (4) CRS + I/R. In the I/R group, the bilateral carotid arteries were clipped for 15 min and the mice were treated with vehicle (corn oil) for 10 days. In the CRS group, CRS (50 mg/kg) was given for 10 days without carotid occlusion. In the CRS + I/R group bilateral carotid arteries were clipped for 15 min and the mice were also treated with CRS (50 mg/kg) for 10 days. All of the rats were sacrificed under anesthesia on day 10, and neurodegenerative histological changes in the brain and tissue levels of oxidants and antioxidants were evaluated.
RESULTS
CRS treatment significantly reversed the oxidative effects of I/R and inhibited the development of neurodegenerative histopathologies. In the CRS + I/R group, the decrease in TBARS levels and increase in GSH levels were similar to those in the SH group.
CONCLUSIONS
Treatment with CRS can positively affect the neural system of mice and it can be used for the treatment of global cerebral I/R.
