Effects of Abnormal Phlegmatic Munziq on Ability of Learning and Memory and Protein Expressions of Brain Tissue RAGE and LRP1 of APP/PS1 Transgenic Mice Model of AD
摘要
Abstract
Objective To investigate the effects of Abnormal Phlegmatic Munziq on ability of learning and memory, and protein expressions of brain tissue RAGE and LRP1 of APP/PS1 transgenetic mice model of AD;To discuss its mechanism of action. Methods Three-month-old APP/PS1 transgenic mice were randomly divided into 5 groups: model control group, positive control group, Abnormal Phlegmatic Munziq high-, medium-, and low-dose groups, 18 mice in each group. Another 18 three-month-old C57BL/6J mice were chosen as normal control group. All administration groups received relevant medicine for successive 6 months. Then the changes in ability of learning and memory of mice were detected by Step-down test; protein expressions of LRP1 and RAGE were detected by immunohistochemistry and Western blot. Results Compared with the normal control group, the reaction time of learning grades and the mistake times increased, incubation of memory grades decreased and the mistake times increased in the model control group (P<0.01);Compared with the model control group, the reaction time of learning grades and the mistake times decreased, incubation of memory grades increased and the mistake times decreased in all administration groups (P<0.05, P<0.01). Immunohistochemistry and Western blot results showed that compared with normal control group, the LRP1 expression decreased and RAGE increased in the model control group (P<0.05);Compared with the model control group, the LRP1 expression decreased and RAGE increased in Abnormal Phlegmatic Munziq high-, medium-, and low-dose groups (P<0.05,P<0.01). Conclusion Abnormal Phlegmatic Munziq can improve ability of spatial learning and memory in APP/PS1 mice and regulate the expressions of RAGE and LRP1.关键词
