AEA Anandamide, IMI(15) imipramine hydrochloride (15 mg/kg), ESC(10) escitalopram oxalate, TIA(ten) tianeptine sodium, NAC(one hundred) N-acetylcysteine, URB597(0.3) cyclohexylcarbamic acid 3-carbamoylbiphenyl-3-yl ester, PFCTXprefrontal cortex, FCTX frontal cortex, HIP hippocampus, DSTR dorsal striatum, NAc nucleus accumbens, CER cerebellum. All data are expressed as the imply ?SEM. N = eight rats/group. p \ 0.05; p \ 0.01; p \ 0.001 versus corresponding vehicle(F(2,21) = 8.311; p = 0.0022), dorsal striatum (F(2,21) = five.787; p = 0.01) and cerebellum (F(two,21) = 17.03; p \ 0.0001). Chronic administration of URB597 evoked an increase of AEA levels in the hippocampus (p \ 0.05), dorsal striatum (p \ 0.05), and cerebellum (p \ 0.001) (Fig. 1). Neither acute administration nor 10-day drug-free period changed the AEA levels inside the examined rat brain structures (Fig. two). For comparison, the levels of AEA measured two h after single administration of URB597 enhanced within the hippocampus (t = four.342, df = 10, p \ 0.01), dorsal striatum (t = three.172, df = ten, p \ 0.01), and cerebellum (t = four.515, df = ten, p \ 0.01) (Table 2).2-AG IMI (15 mg/kg) remedy resulted inside a transform within the 2-AG levels in the frontal cortex (F(2,21) = six.385; p = 0.0068), dorsal striatum (F(2,21) = 11.37; p = 0.0005), and cerebellum (F(2,21) = 7.035; p = 0.0046). The 2-AG levels either enhanced in the frontal cortex (p \ 0.05) or decreased within the cerebellum (p \ 0.05) after acuteadministration of IMI. IMI administered chronically evoked an increase of 2-AG levels inside the frontal cortex (p \ 0.01) and dorsal striatum (p \ 0.001), even though in the cerebellum (p \ 0.01) decreased 2-AG levels have been reported (Fig. 3). A 10-day washout period soon after chronic remedy of IMI restored the levels of 2-AG for the levels of vehicletreated animals in all structures (Fig. four). Administration of ESC (10 mg/kg) resulted in potent changes in the 2-AG concentration inside the prefrontal cortex (F(2,21) = 6.169; p = 0.0078), frontal cortex (F(two,21) = 8.656; p = 0.0018), hippocampus (F(two,21) = three.447; p = 0.0508), dorsal striatum (F(two,21) = three.848; p = 0.0377), and cerebellum (F(two,21) = 3.843; p = 0.0378). ESC administered acutely decreased the 2-AG levels within the frontal cortex (p \ 0.05). Chronic administration of ESC brought on a reduction inside the 2-AG levels inside the prefrontal cortex (p \ 0.01), frontal cortex (p \ 0.01), and cerebellum (p \ 0.05), though an increase of 2-AG concentration was observed in the hippocampus (p \ 0.05) and dorsal striatum (p \ 0.05) (Fig. 3). Just after 10-day drug-free period a rise of 2-AG levels was noted only within the hippocampus (t = 2.272, df = 14, p \ 0.05) and dorsal striatum (t = 3.062, df = 14, p \ 0.01) (Fig. 4).Neurotox Res (2014) 26:190?Fig. 2 AEA levels in rat brain structures following chronic drug/ compound administration and 10-day washout period.
