Effect of Bailiang tea extract on learning and memory ability of mice

Recently, researchers from the Second Affiliated Hospital of Hunan Normal University and the 163 Hospital of the PLA published a paper to observe the effect of Bailiang tea extract on memory of mice The results showed that the extract of Bailiang tea could improve the learning ability of mice This article was published in the Journal of Hunan Normal University (Medical Edition), the first issue in 2014 Mice were given different doses of tea extract (100 mg / kg, 200 mg / kg, 400 mg / kg) by gavage for 30 days After the last administration, water maze test was carried out to observe the time of mice's standing on the stage and the time of Memory fading After the experiment, the blood was collected from the vein of the inner canthus of mice, and then the brain and liver were taken to detect the levels of LG, Mg, SOD and GSH px 1 The low, middle and high doses (100 mg / kg, 200 mg / kg, 400 mg / kg) of Bailiang tea extract can significantly shorten the time of mice on stage; the high dose (400 mg / kg) group can significantly prolong the time of mice on stage memory regression 2 The low, middle and high doses (100 mg / kg, 200 mg / kg, 400 mg / kg) of Bailiang tea extract can increase the levels of Mg and LG in the blood of mice 3 The low, middle and high doses (100 mg / kg, 200 mg / kg, 400 mg / kg) of Bailiang tea extract can improve the activity of SOD and GSHPx in mice.
