Abstract | PURPOSE: METHODS: In order to create Alzheimer's rat model, bilateral injection of Amyloid β1-42 (Aβ1-42) into rats hippocampus was performed. Both therapeutic (post-AD induction) and preventive effects of p-cymene consumption with doses of 50 and 100 mg/kg were investigated. In addition, the effects of adding short-term exercise to the process were also observed. In vitro, Aβ1-42 peptide was driven toward fibril formation and effect of p-cymene was observed on the resulting fibrils. RESULTS: Learning and memory indices in the AD rats were significantly reduced compared to the Sham group, while p-cymene consumption with both doses, as well as performing exercise counteracted AD consequences. Moreover, increased neurogenesis and reduced amyloid plaques counts were observed in treated rats. In vitro formed fibrils of Aβ1-42 were partially disaggregated in the presence of p-cymene. DISCUSSION:
p-Cymene could act on this AD model via antioxidant and anti-inflammatory properties as well as direct anti-fibril effect. CONCLUSION:
p-cymene can improve AD-related disorders including memory impairment.
