Poster summary

The aim of this work is to evaluate the neuroprotective effects of SA in the modulation of behavioral and motor alterations and cerebral nitrite levels induced by 6-OHDA intrastriatal injection in rats. Male Wistar rats (250-300 g) were randomically divided in five groups. Rats were anesthetized and treated with SA (15, 30 or 60 µg) + 6-OHDA (20 µg); 6-OHDA (20 µg) only; or saline (sham group). All treatments were realized through stereotaxic injection into right striatum and solutions were prepared in saline (0.9%; with 0.01% ascorbic acid). Fourteen days later, rats were submitted to behavioural evaluation by open-field test and rotational test induced by apomorphine (3 mg/Kg). After, animals were euthanized and hippocampus, cortex and striatum were removed to measure nitrite levels. SA presented neuroprotective effects against motor alterations induced by 6-OHDA injection into striatum and recovered the nitrite levels in the rat cerebral tissues.
