Effects of Wuweizi syrup on brain aging mice model induced by d-galactose

Objective: To observe the effect of Wuweizi syrup on brain aging mice model induced by d-galactose in mice. Methods: 72 mice were randomly divided into blank group, model group, naokangling group and low, middle and high dose Wuweizi syrup group. After 3 days of adaptive feeding, except for the blank group, the rest mice were subcutaneously (sc) injected with d-galactose 1.25 g/kg at neck back to replicate the aging model. Sc injection was given for 40 consecutive days, and corresponding drugs were given by gavage on the 11th day of modeling. On the 39th day, the dark experiment was carried out to measure the learning ability of mice. After the last administration for 2 h, brain, liver, thymus and spleen were taken and weighed to calculate the organ index. Blood was taken and CAT, GSH and SOD levels in whole blood were determined. Some brain and liver tissues were taken to prepare homogenates, and MDA levels in tissue homogenates and plasma were measured. Brain, liver, thymus and spleen were stained with HE, and pathological sections were made for observation under light microscope. Results: Compared with the blank group, in the model group, the incubation period of mice was significantly reduced and the number of shuttle back and forth was significantly increased (P
