dong物代谢xi统由不同的chuan感器组成,并为每一zhongdong物duzheng合了大量的信息。dong物代谢ce量fen析xi统ke以zidong地,无干涉地长qi对大量的dong物进行监ce(24小时shen至连续几天)。dong物代谢ce量fen析xi统同时大鼠和小鼠在笼的居住环境中监ce几组生li和行为的参shu。
 
 
dong物代谢xi统Oxylet 是一tao模kuai化的xi统,研究者ke选择性地对dong物的呼吸代谢(O2消耗和CO2产出)、yin蔯heng難in水量、运dong活性和站立行为等进行fen别监ce,并将研究shuju结合起来进行fen析。

    dong物代谢xi统Oxylet的dong物笼采yongAllentown Caging Equipment(ACE)生产的biao准dong物笼ti并进行进一bu加工。笼ti耐高温高压处li,bian于**清li。笼ti以外的其它配件:密闭笼盖、网格地板、yin食和yin水槽等,duke以单独ding制。特别是,独特设计的密闭笼盖ke以改biandong物笼的空间,shi一tao呼吸检cexi统ke以同时适yong于大鼠和小鼠shiyan。

在居住笼中的活dong

转轮跑tai等活dong(ke选)

1.yin蔯heng難in水监ce:

   Panlabzi主研fa的ling敏zhong力chuan感jishu取代了chuan统的外置电子cheng来对dong物yin食yin水量进行监ce。chuan感器、电信haofang大器和shu模转换器等ling敏yuan件被wan全zheng簒ian诹齮ixiabu的金属底座(Platform)内。Platformmian板提供了wanzheng的操作按niu,并有LEDxian示屏xian示当qian的shuju。yin食、yin水槽的zhong量bian化,通过巧miao设计的导力支架被平tai内的chuan感器jie收,其中食物和水的ce量jingdufen别高达0.02g和0.01g!shi际ce量中的xi统扰dong误差值也fen别控制在0.02g和0.01ml以内!yin食yin水监ce达到如此高的**du和稳ding性在市场中****!
  
yin食槽和yin水槽fen别采yong了巧miao的hui收设计,将dong物进食过程中泄漏的食物和水hui收并从真shishuju中zidong去除,大大提高了长qi记录的shujujingdu。

综合以上性能特点,shiPanlab Oxyletxi统ke以真zhengyong于小鼠的摄入代谢长qi监ce。

为了满足特ding的研究需要,如研究dong物对不同shi物的偏好和yin食模式等,其中的yin食和yin水槽还ke以fen别huxiang替换,例如改装两geyin食槽、两geyin水槽。




2.呼吸代谢检ce: 

   dong物代谢xi统Oxylet呼吸代谢的ce量原li是通过检cedong物呼吸气ti中O2和CO2成fen的bian化间jie的计suan出dong物能量的消耗,   这也是目qianshiyanshiyong于啮齿类dong物能量代谢检ce常yong的方式。
  
 dong物代谢ce量fen析xi统Oxylet的气tiliu量控制器保证在密闭笼ti中wei持恒ding的空气liu量,liusuke以在0至20L/min内连续**地设ding。liusu的**diao节,保证了无论dong物处于剧烈运dong还是休眠状态,duke以得到十fen有效的呼吸代谢shuju。该liu量控制器一般为2通道或4通道设计,例如一kuan4通道Oxyletliu量控制器ke以独立地fen别控制4ge笼ti的空气liudong。通过独特的笼盖设计,shi笼ti内的空间根jushiyandong物的不同而改bian,fen别适yong于大鼠和小鼠。

  
     dong物代谢xi统主要特点:

dong物代谢监cexi蚦heng衵i己的biao准组成bufen。这xiebufen模kuai化地结合和组成起来,并根ju您不同的需要为您的科研提供有效的工ju


 


经过liu量控制的气liu被采样输入至xi统中*核心的bu件——气ti成fenfen析仪。fen析仪中安fang了ling敏的光电二极管氧气tan头、和红外感应二氧化碳tan头来jing譲i嗫仄鴗i成fen的改bian,采集jingdu达到*高的0.01%。该xi统还能在一xie特殊的研究场合shiyong,如新生大鼠的wei弱呼吸代谢检ce、于Treadmill跑bu机运dong同bu的能量消耗检ce等。

Oxylet软件能zidong计suan平jun氧气消耗(VO2)、平jun二氧化碳pai量(VCO2)、以及呼吸商(RQ=VCO2/VO2),并zidong按以xia公式推suan换能率:
EE=(3.815+(1.232xRQ))xVO2x1.44

• re量检ce仪能ce量O2 消耗量(VO2), CO2产生量 (VCO2), 呼吸交换率(RER), re量的产生以及温du。
• 量re计直統ing饬亢蚦hu存shiyan时间日qi,笼内O2 和 CO2 浓du,空气liusu和温du(以每ge笼为单位),计suanVO2, VCO2,RER 和 re量。
• 量re计特殊的dong物笼能连jie空气进气管,出气管,独立的样pin连jie以及ke选的温duchuan感器。
• 呼吸代谢检ce仪高jingduchuan感器能准确ce量O2, CO2 浓du,温du和气liu控制。


3.运dong活性和站立(Rearing)监ce

   dong物代谢ce量fen析xi统Oxyletxi统通过位于笼ti底bu四脚的振dongchuan导装置以及位于Platform上xiang应位置祅ao薲ongchuan感器感受dong物运dong活性;通过架设独立的一对红外感应条来监cedong物站立行为。平tai内祅ao薲ongchuan感器能感受到dong物非常wei小的活dong,ke**地yong于小鼠活dong监ce。红外感应条作为附加模kuai,ke以为有站立行为研究需要者选购。dong物活dong性shujuke以直jie导入计suan机中由专门的软件模kuaiMETAACTfen析和生成shuju图biao,襜u梢栽诿縢e笼子xia方Platform的LEDxian示屏中shi时查看到。

两zhong运dongchuan感器:

-- 在X,Y,Zsanwei方向上,红外光柱chuan感器支架baowei饲养笼

---在笼盖顶端,安装红外rechuan感器,yong于监ce总运dong

 

为shi现运dongce量,dong物笼fang在红外光柱chuan感器支架内。光柱chuan感器安装在X和Y方向上,此外ke以bu充kediaozheng的高duZ(垂直于X),yong于站立指示器。光柱被截秞i淖刺?孀興ong物祅ao薲ong而bian化。每gebian化du将登记为一次计shu。这意味着如果长久性截断光柱将不被计shu。

 

通过安装在笼盖蓌i暮焱馕粂ichuan感器,能方bian的ce量饲养笼内的大小鼠或其他小型shiyandong物的总运dong。ke以在任he光线条件xiace量运dong。ce量shen至ke以在全黑的情况xia进行。chuan感器记录一ge或多ge物ti运dong,是通过感应tire图进行的,也就是说通过红外辐射,然后将其空间位yi作为时间的函shu。这zhong方法能确ding笼内祅ao薲ong并进行ding量。这shen至能记录一ge只li时几ge毫秒祅ao薲ong。
