چکیده

Objective(s): In this study the effect of crocin, a carotenoid isolated from saffron, on malathion (an organophosphate insecticide) induced depressive- like behavior in subacute exposure was investigated. Moreover the molecular mechanism of malathion induced depressive- like behavior and its decreasing effect on the level of brain derived neurotrophic factor (BDNF) in rat hippocampus and cerebral cortex were evaluated. Materials and Methods: Male Wistar rats were exposed to malathion (۵۰ mg/kg/day, IP) alone or in combination with crocin (۱۰, ۲۰ and ۴۰ mg/kg/day, IP), imipramine (۲۰ mg/kg/day, IP) and vitamin E (۲۰۰ mg/kg, three times a week, IP) respectively for ۱۴ days. The forced swimming test (FST) was performed on days ۱st, ۷th and ۱۴st. The level of malondealdehyde (MDA) and reduced glutathione (GSH) were measured in cerebral cortex and hippocampus of rats. The protein level of BDNF was evaluated using Western blot analysis. Results: Malathion (۵۰ mg/kg, IP) increased immobility time in the FST, without affecting total locomotor activity in open-field test. Malathion increased the malondealdehyde (MDA) and decreased the glutathione (GSH), whereas these effects were reversed by crocin and vitamin E. Malathion decreased plasma acetylcholinesterase  activity,  however  this effect was not reversed by crocin or vitamin E. Malathion reduced the protein level of BDNF in rat hippocampus. Imipramine and crocin  prevented the decreasing effect of malathion on BDNF. Conclusion: These results showed that crocin attenuates some neurochemical and behavioral effects induced by malathion. This neuroprotective effect of crocin may be in part due to its effect on BDNF.
