The results showed that the enzyme activities in the Dgal treated mice did not alter appreciably but the enzyme activities in blood of the SAM declined significantly with the increase in age, especially in the 9-month-old SAM. When gallic acid purified from rose flowers was used to treat the 9-month-old male SAM, it not only reinstated the activities of CAT and GPx but also significantly reduced the amount of malondialdehyde (MDA)in the liver, brain and kidney. The results demonstrated that 9-month-old male SAM represent an appropriate animal model to evaluate the antioxidant activities of natural products.14aANIMAL MODELS14aCAT14aGPX12aLi, L.12aNg, T.B.12aGao, T, W.12aLi, W.12aFu, M.12aNiu, S.M.12aZhao, L.12aZhao, L.12aLiu, F.40uhttps://drive.google.com/file/d/1oXpKaxUR09A01O1SeF_jLjFoEscDviNq/view?usp=drivesdkzPara ver el documento ingresa a Google con tu cuenta: @cicy.edu.mx250602s9999    xx |||||s2   |||| ||und|d
