ABSTRACTObjective: To study the protective role of fruit extract of Anacardium occidentale (cashew apple) in aluminum-induced cognitive dysfunction andoxidative damage in albino rat, and to explore the neuroprotective effect of A. occidentale represented by behavior and memory tests.Methods: Male Wistar rats (30) were divided into 5 groups of 6 rats each. Group I received normal saline. Group II was administered orally withaluminum chloride (100 mg/kg). Group III received rivastigmine 0.3 mg/kg body orally. Groups IV and V were administered with A. occidentale200 and 400 mg/kg along with aluminum chloride of 100 mg/kg orally after 1 hr interval. The study was carried out for 42 days (6 weeks). Thebehavioral assessment was performed using Rota-rod apparatus and Elevated plus maze and Biochemical parameters from brain homogenate such asacetylcholinesterase activity, total protein, lipid peroxidation malondialdehyde, superoxide dismutase (SOD), catalase, and glutathione reductase (GR)were estimated. All the data were analyzed using one-way analysis of variance followed by Tukey’s multiple comparison test.Results: The % reduction of acetylcholinesterase, GR observed in A.O (400 mg/kg) dose as compared with that of standard drug was found to be87.5% and 89%, respectively, whereas % reduction of catalase and SOD observed in A.O (400 mg/kg) dose as compared with that of standard drugwas found to be 97% and 99%, respectively.Conclusion: This study demonstrates A. occidentale fruit has a neuroprotective effect against aluminum-induced behavioral changes.Keywords: Occidentale, Neuroprotective, Alzheimer’s disease, Aluminum.

<b><i>Objective:</i></b> The purpose of this study was to explore the role of curcumin (Cur) in isoflurane (ISO)-induced learning and memory dysfunction in Sprague-Dawley rats and further elucidate the mechanism of the protective effect produced by Cur. <b><i>Methods:</i></b> Rat models of cognitive impairment were established by inhaling 3% ISO. The Morris water maze test was used to assess the cognitive function of rats. ELISA and qRT-PCR were used to analyze the protein levels of pro-inflammatory cytokines and expression levels of miR-181a-5p, respectively. <b><i>Results:</i></b> Cur significantly improved the ISO-induced cognitive dysfunction in rats and alleviated the ISO-induced neuroinflammation. miR-181a-5p was overexpressed in ISO-induced rats, while Cur treatment significantly reduced the expression of miR-181a-5p. Overexpression of miR-181a-5p promoted the cognitive impairment and the release of inflammatory cytokines and reversed the neuroprotective effect of Cur. <b><i>Conclusion:</i></b> Cur has a protective effect on ISO-induced cognitive dysfunction, which may be achieved by regulating the expression of miR-181a-5p.

Given the medicinal importance of the avocado plant in alternative medicine,the present study aimed to study the effect of the phytochemical content of P. americana leaf extract on the hematological system of albino rats. Albino rats were obtained andclustered into sixgroups,with five rats per groupsimultaneously were assigned experimental and control. The rats in the experimental group were administered with varying doses of the prepared aqueous extract of P. americanawithin the period of the study. The rats in the control group were administered with other substances such as water and feed for the study period.The hematological system of the experimental animal was assessed after the administration of the extract, and it was observed that the aqueous extract of P. americana leaf recorded no significant adverse effect on the hematology system of the experimental study animal.
