Abstract:
Objective To study the effect of noise on the ability of learning and memory of mice,and observe the effect of herba Houttuyniae injection on the change of the ability of learning and memory in noise condition, and then analyses the mechanisms. Methods To choose suitable mice and divide into groups, applying Y-maze and colorimeter to determine the content of MDA and the enzyme activity of SOD, AChE and NOS of mice brain. Results Learning group in Y-maze, noise cause the ability of noise group (12.1±1.20) decrease(P＜0.01) compared with the control group(15.1±1.45), but herba Houttuyniae injection can reverse the ability of the mice, the correct frequency is much higher(P＜0.01)in herba Houttuyniae group(14.9±1.60). The results is same in the memory group, in Y-maze, noise cause the memory ability of noise group (5.20±1.40) decrease(P＜0.01) compared with the control group(6.30±1.32), but herba Houttuyniae injection can reverse the memory ability of the mice, the correct frequency is much higher(P＜0.01)in herba Houttuyniae group(6.10±1.10). Either learning or memory group mice, noise can decreased the activity of SOD and NOS of mice brain(P＜0.01), but the content of MDA and the ability of AChE elevated(P＜0.01). herba Houttuyniae injection can change the effect of noise to mice, the activity of SOD and NOS of mice brain elevated(P＜0.01) and the content of MDA and the ability of AChE decreased (P＜0.01). Conclusion herba Houttuyniae injection can prevent the ability of learning and memory of mice which decreased by noise, and have the effect of intoxication.
