【摘要】目的观察长期蚊香熏染环境对小鼠学接近的20只小鼠随机分为蚊香组和对照组,每组10只。蚊香组每天置于蚊香环境中8 h,对照组正常饲养。7天后,对2组小鼠进行避暗实验,记录、比较停止熏染后0 h、24 h、48 h各组小鼠的潜伏期和错误次数。结果停止熏染蚊香后0 h,蚊香组小鼠错误次数比对照组多,潜伏期较之缩短(P<<);停熏后24 h和48 h两组间各指标差异无统计学意义(P>)。结论长期使用蚊香会妨碍小鼠短时间内学忆能力影响不明显。

Abstract: Objective To investigate the effects of long-term use of mosquito-repellent incense coils on the learning and memory in mice. Methods 20 mice ilar intelligence 40 mice and ly divided into 2 groups: mosquito-repellent incense group and the control group (n =10 each). Mice in mosquito-repellent incense group ent of burning mosquito-repellent incense coils for 8 h per day, als in the control group al conditions. 7 days later, step-through tests ice in both groups. The latencies and the numbers of errors at such time points as 0 h, 24 h and 48 h after incensing bers of errors increased and the latencies shortened as pared to the control group (P<, P<). Hoeters at 24 h and 48 h bet use of mosquito-repellent incense coils can hinder the learning and memory abilities in mice e, learning and memory.
