Effect of low intensity pulsed ultrasound on the morphology of microglia in hippocampus of mice
摘要
Abstract
Objective To study the effect of low intensity pulsed ultrasound on the hippocampus and to study its possible mechanism in mice.Methods Totally 32 adult C57/BL6 mice were randomly divided into the sham group(n=16)and the LIPUS group(n=16).Mice in the sham group were treated with sham operative,while mice in the LIPUS group were treated by low intensity pulsed ultrasound(average power density of 150 mW/cm2).After 7 days of treatment,immunohistochemical(IHC)and western bolt(WB)were used to determine the expression of DCX,GFAP,and Iba1 in the hippocampus,and the behavioral changes of mice in open field test were observed.Results After 7 days of treatment,the results of IHC showed that the number of microglial cells in the LIPUS group were significantly increased,and the difference was statistically significant compared with that in the sham group(P<0.05).The WB results indicated that the expression of Iba 1 protein in hippocampus was significantly increased in LIPUS group compared with that in the sham group(P<0.05).In the meantime,the behavior score of LIPUS group in the open field test was increased significantly(P<0.05).Conclusion Low intensity pulsed ultrasound can increase the number of microglia in the hippocampus and reduce the anxiety of the mice.关键词
