IN-VITRO NEUROPROTECTIVE ACTIVITY OF SILIBININ AGAINST MPTP (1-METHYL-4-PHENYL-1, 2, 3, 6-TETRAHYDROPYRIDINE) INDUCED NEUROTOXICITY MODELAbstract
In the present study, we examined the effect of Silibinin on the accumulation of oxidative stress induced by MPTP by in-vitro. After decapitation, healthy rat brain was removed rapidly from the skull and rinsed with cold artificial cerebrospinal fluid (ACSF) which has been equilibrated with 95% O2 / 5% CO2 gas mixture. Group I brain was incubated in CSF serve as normal, Group II lenses brain was incubated in CSF and DMSO (10%) serve as disease, Group III brain was incubated with MPTP (1 ng/mL) Group IV brain was incubated in MPTP with bromocriptine (10 µg/mL), Group V brain was incubated in MPTP with Silibinin (10 µg/mL) Group VI brain was incubated in MPTP with Silibinin (20 µg/mL). After 1 h of incubation brain slices were homogenized in PBS buffer, pH 7.4 and estimated for protein content, LPO* and GSH as per the procedures. MPTP incubated brain LPO* levels were increased, and GSH activity decreased compared to normal group. Silibinin treated group brain LPO* levels were significantly decreased and GSH activity was increased. The research results were concluded that the Silibinin exhibited significant neuroprotective effect against MPP + free radicals due to their antioxidant activity.
