Abstract
The aim of present
study was to determine the effect of 3′,4′-dihydroxyflavonol (DiOHF) on
lipid peroxidation in experimental brain ischemia–reperfusion in rats.
Present study was performed on the 34 male Wistar-albino rats, weigth
350-400 g. Experiment groups were designed as 1-Sham;
2-Ischemia–reperfusion; animal were anesthesized and carotid arteried
were clemped for 20 min and reperfusion (7 days).
3-DiOHF + Ischemia–reperfusion; DiOHF was given to animals as 10 mg/kg
by intraperitoneal. 4- Ischemia + DiOHF + Reperfusion; 5-
Ischemia–reperfusion + DiOHF. Blood samples and serebral cortex were
analysed for malondyaldehyde (MDA), NO (nitric oxide), xanthine oxidase
(XO), glutathione (GSH) and glutathione peroxidase (GPx). Blood MDA
levels were significantly higher ischemia–reperfusion groups (P < 0.005).
However, DiOHF inhibited MDA. Ischemia–reperfusion led to increased XO
and NO but DiOHF supplementation reduced NO and XO. DiOHF increased GSH
and GPx levels compared to ischemia–reperfusion group. All together, our
present study showed that intraperitoneal DiOHF supplementation has
protective effect on brain ischaemia–reperfusion injury in rat.
