Abstract

Background: Ischemic stroke produces oxidative stress in neurons and neuroglial, triggering a cellular response with HSP27 as one of the markers. Extra virgin olive oil (EVOO) is reported to act as a neuroprotection by inhibiting reactive oxygen species, which can modulate HSP27. Objective: To analyze the potential neuroprotection of EVOO containing 7-g MUFA on the expression of HSP27 in the cerebral cortex of Rattus norvegicus Wistar strain middle cerebral artery occlusion (MCAO) model. Design: MCAO-Rattus norvegicus Wistar male rodents (n = 32), randomly divided into negative control (sham), positive control (P0), MCAO added EVOO 0.5 mL/kg body weight (P1), and MCAO added EVOO 2 mL/kg body weight (P2); the experiment was conducted 14 days. The nuclei of neurons, glial, and expression of HSP27 on the cerebral cortex were analyzed using Image J software, data were compared between groups with a significance level of P < 0.05. Results: There were significant differences in the neuron and glia nuclei numbers between groups (P = 0.01). There was also a significant difference in cerebral cortex HSP27 expression between groups (P = 0.006). Conclusion: There was a significant down-regulated of HSP27 in the cerebral cortex of the male Rattus norvegicus Wistar strain MCAO model given EVOO with 7 g of MUFA content at a dose of 0.5–2 mL/kgBW.
