  Alzheimer's Disease is the most common form of dementia, characterized by memory and cognitive deficits. Vitamin E, as an antioxidant, plays an important role in reviving free radicals and converting them into safe substances by giving hydrogen. Shirazi thyme (Zataria multiflora) has antibacterial, antifungal and antioxidant properties. The aim of this study is the comparative effect of timolol with methanol extract of Zataria multiflora with vitamin E on Alzheimer's disease in male Wistar rats. 40 male Wistar rats weighing approximately 200 grams were randomly divided into 5 groups of eight. Beta-amyloid 42 was used to induce Alzheimer's disease. Then, methanolic and timolol extracts were extracted from Zataria multiflora. The level of Apo E gene expression was evaluated by Real Time PCR and TC, LDL and HD biochemical factors. The expression of Apo E gene in the experimental groups increased significantly compared to the Alzheimer's group. The expression of this gene was decreased in the sham group compared to the control group. The group of Alzheimer's mice had a significant increase in total cholesterol (TC) and low-density lipoprotein (LDL) serum levels, and the level of HDL showed a significant decrease compared to the control group. Timolol, m ethanolic extract of Zataria multiflora and vitamin E have positive effects on the expression of APOA E gene in leukocytes. On the other hand, with a significant effect on HDL, the methanolic extract of Zataria multiflora can be used as an effective product to prevent and reduce the complications of Alzheimer's disease.   Manuscript profile
