摘要
目的探讨明暗箱实验(light/dark box,LDB)作为昆明小鼠状态焦虑动物模型的影响因素。方法昆明小鼠(♂)进行LDB实验,实验参数有明区停留时间百分率(Ltime%)、明区水平运动百分率(Lcross%)、明区垂直运动百分率(Lrear%)、水平运动总得分(Cross)、垂直运动总得分(Rear)、总得分(Total=Cross+Rear)、穿梭次数(Transition)以及粪便总粒数(Fbs);考察因素有昼夜节律、光照面积、光照颜色、光照强度。结果t检验提示,昼夜节律对LDB实验参数无明显影响,光照面积(L3/5,L2/5)可分别升高LDB实验参数Lcross%、Lrear%;析因设计ANOVA提示,昼夜节律对LDB实验参数无影响,而光照面积对LDB实验参数Ltime%、Lcross%、Lrear%有明显影响;单因素ANOVA提示,光照颜色对LDB实验参数Rear、Fbs有明显影响,光照强度对LDB实验参数Cross、Total有明显影响;Dunnett t检验提示,Yellow光照颜色可降低LDB实验参数Rear,100 W光照强度可降低LDB实验参数Cross、Total;Kruskal-Wallis检验提示,光照颜色和光照强度对Fbs无明显影响。结论LDB用于评价啮齿类焦虑、运动探索及情绪性相关行为,实验参数不受昼夜节律影响,而受光照面积、光照颜色、光照强度影响。
Aim To explore the factors on behavior patterns of light/dark box(LDB)as an animal model of state anxiety in Kunming mice.Methods The behavior of adult,male,Kunming mice in LDB was recorded for five minutes,respectively.The following parameters were evaluated:percentage of time in the light area(Ltime%),percentage of squares crossing in the light area(Lcross%),percentage of rears in the light area(Lrear%),total number of squares crossing in the whole apparatus(Cross),total number of rears in the whole apparatus(Rear),total(Cross plus Rear),transitions between two areas(Transition),and number of fecal bolis in light box and dark box(Fbs).Subsequently,the factors,such as day-night rhythm,illumination area(L3/5 or L2/5 for ratio between Light box and Dark box:3∶2 or 2∶3,respectively),illumination color(in Dark box)and illumination intensity(in Light box),were investigated to screen the best experimental conditions.Results t-test showed that compared with night cycle,there was no significant difference in all LDB parameters during day cycle(P>0.05),while compared with 3/5 and 2/5,LDB parameters during day cycle such as Lcross%(t=5.363,P<0.01)in big area light box(L3/5),Lrear%(t=3.211,P<0.05)in small area light box(L2/5)increased statistically.The factorial design ANOVA showed that there was no significant difference in day-night rhythm on all LDB parameters(P>0.05),but a statistical influence of illumination area on Ltime%(F(1,20)=18.361,P<0.01),Lcross%(F(1,20)=49.148,P<0.01)and Lrear%(F(1,20)=8.424,P<0.01).The single factor ANOVA showed that there was significant influence of illumination color in dark box on Real(F(3,20)=3.746,P<0.05),Fbs(F(3,20)=3.585,P<0.05),and illumination intensity in light box on Cross(F(4,25)=2.569,P<0.05)and Total(F(4,25)=2.588,P<0.05).The Dunnett t test showed that compared with red color group,Rear(MD=-30.833,P<0.05)was significantly lower in yellow color group;while Cross(MD=-173.167,P<0.05)and Total(MD=-93.667,P<0.05)in 100 W group declined statistically compared with 15 W Group.Kru
