ABSTRACT

 

Harandi S, Abbasnejad M, Mirnajafi-Zadeh J, Esmaeili-Mahani S, Esmaeilpour K, Asadi-Shekaari M, Mostafavi A, Sheibani V., Inhibitory effects of walnut consumption on amygdala kindling model of epilepsy in male Wistar rats, Onl J Vet Res., 17(7):360-369, 2013. Bipolar stimulation and monopolar recording electrodes were planted stereotaxically in the right basolateral amygdala of 4 groups of 6 male Wistar rats each. Groups were given a daily IP injection of saline for 2 weeks, fed 1.2g walnuts daily for 2 months, or injected daily IP 4.5ng melatonin for 2 weeks. Controls were untreated normal rats. After treatments all rats were subjected to kindling stimulation. Duration of after discharges, daily seizure stages, walnut melatonin concentration and serum melatonin were then determined in all rats. In groups given walnut kernels or injected with melatonin (to induce the same concentration as the ingestion of 1.2g walnuts), there was significant increase in serum melatonin.  In rats ingesting walnuts there was a significant inhibitory effect on epileptogenesis compared with control or saline groups which may possibly be attributed to the high melatonin content of these nuts.
