Objective. To investigate neuroprotective effects of scutellarin (Scu) in a rat model of cerebral ischemia with use of18F-fluorodeoxyglucose (18F-FDG) micro positron emission tomography (microPET).Method. Middle cerebral artery occlusion was used to establish cerebral ischemia. Rats were divided into 5 groups: sham operation, cerebral ischemia-reperfusion untreated (CIRU) group, Scu-25 group (Scu 25 mg/kg/d), Scu-50 group (Scu 50 mg/kg/d), and nimodipine (10 mg/Kg/d). The treatment groups were given for 2 weeks. The therapeutic effects in terms of cerebral infarct volume, neurological deficit scores, and cerebral glucose metabolism were evaluated. Levels of vascular density factor (vWF), glial marker (GFAP), and mature neuronal marker (NeuN) were assessed by immunohistochemistry.Results. The neurological deficit scores were significantly decreased in the Scu-50 group compared to the CIRU group (P<0.001).18F-FDG accumulation in the ipsilateral cerebral infarction increased steadily over time in Scu-50 group compared with CIRU group (P<0.01) and Scu-25 group (P<0.01). Immunohistochemical analysis demonstrated Scu-50 enhanced neuronal maturation.Conclusion.18F-FDG microPET imaging demonstrated metabolic recovery after Scu-50 treatment in the rat model of cerebral ischemia. The neuroprotective effects of Scu on cerebral ischemic injury might be associated with increased regional glucose activity and neuronal maturation.

Background: The conifer species Pinus halepensis (Pinaceae) and Tetraclinis articulata (Cupressaceae) are widely used in traditional medicine due to their health beneficial properties. Objective: This study aimed to investigate the mechanisms by which P. halepensis and T. articulata essential oils (1% and 3%) could exhibit neuroprotective effects in an Alzheimer's disease (AD) rat model, induced by intracerebroventricular (i.c.v.) administration of amyloid beta1-42 (Aβ1-42). Method: The essential oils were administered by inhalation to the AD rat model, once daily, for 21 days. DNA fragmentation was assessed through Cell Death Detection ELISA kit. Brain-derived neurotrophic factor (BDNF), activity-regulated cytoskeleton-associated protein (ARC) and interleukin-1β (IL-1β) gene expressions were determined by RT-qPCR analysis, while BDNF and ARC protein expressions were assessed using immunohistochemistry technique. Results: Our data showed that both essential oils substantially attenuated memory impairments, with P. halepensis mainly stimulating ARC expression and T. articulata mostly enhancing BDNF expression. Also, the inhalation of essential oils reduced IL-1β expression and induced positive effects against DNA fragmentation associated with Aβ1-42-induced toxicity, further contributing to the cognitive improvement in the rats with AD-like model. Conclusion: Our findings provide further evidence that these essential oils and their chemical constituents could be natural agents of therapeutic interest against Aβ1-42-induced neurotoxicity.
