The dissertation, titled “A Comparative Study of the Therapeutic Role of the Alcoholic and Nano-Extracts of *Portulaca oleracea* and the Drug *Glimepiride* in Male Rats Induced with Type 2 Diabetes,” was conducted by researcher Sarmad Ali Abbas and supervised by Professor Dr. Hussein Abbas Salman.

The main findings indicate that the induction of diabetes in male albino rats resulted in changes in the studied physiological and biochemical parameters. The plant extract demonstrated significant efficacy in improving physiological and histological parameters in male albino rats treated with the alcoholic and nano-extracts of *Portulaca oleracea*. The nano-extract, at a concentration of 10 mg/kg of body weight, was effective in reducing the resulting tissue damage. From Diabetes

Key recommendations include studying the effects of nano-Portulaca oleracea at the molecular and nano levels, and investigating other plant species from the same family to determine which is most beneficial and effective in preventing and treating the damage caused by diabetes. Further studies should also be conducted to investigate the positive effects of Portulaca oleracea on other organs, such as the kidneys and brain, in animals with diabetes.
