Saffron and crocin ameliorate prenatal valproic acid-induced autistic-like behaviors and brain oxidative stress in the male offspring rats

This study aimed to determine the effects of saffron extract and crocin against brain oxidative stress and behavioral, motor, and cognitive deficits in an animal model of autism in male offspring rats. 14 female rats were randomly divided into the saline and valproic acid (VPA) groups. Then, they were placed with mature male rats to mate and produce offspring. VPA (500  mg/kg, i.p.) was injected on day 12.5 of pregnancy (gestational day, GD 12.5) to induce an experimental model of autism. 48 male pups were left undisturbed for 29 days. First-round behavioral tests (before treatments) were performed on 30–33 post-natal days (PND), followed by 28 days of treatm ent (PND 34–61) with saffron (30 mg/kg, IP), crocin (15 or 30 mg/kg, i.p.), or saline (2 ml/kg, i.p.). The second round of behavioral tests (after treatments) was performed on PND 62–65 to assess the effects of the treatments on behavioral and cognitive features. In the end, animals were sacr ificed under deep anesthesia, and their brains were dissected to evaluate the brain oxidative stress parameters, including malondialdehyde (MDA), glutathione (GSH), and catalase (CAT). VPA injection into female rats increased anxiety-like behaviors, enhanced pain threshold, impaired motor functions, disturbed balance power, increased MDA, and decreased GSH and CAT in their male offspring. 28 days of treatment with saffron or crocin significantly ameliorated behavioral abnormalities, reduced MDA, and increased GSH and CA...
