实验室又要开始测实验动物的体温了,师兄师姐们开始唉声叹气:几十只小动物,每隔五分钟记录一次体温,连续测量十二小时的体温变化。。。
用红外线体温计或接触式体温探头测量小动物的体温,它们身上那层平时让你撸起来爱不释手的毛茸茸,成了体温计与皮肤直接的阻碍,想要他们亲密接触,还要一只只给小动物们剃毛,一不小心一个喷嚏下来,毛毛满天飞。这就算了,还要隔几分钟测量一次体温,操作简单而繁琐,一不小心时间看错了,又得重新来!
用肛温计测量动物的直肠温度吧,结果会更准确,但需要让动物处于麻醉状态。这一步骤却直接导致实验操作更复杂:或麻醉过深,动物直接死亡,或麻醉过浅,动物在实验途中醒来;实验过程也不能长,至多只能获得几小时的体温变化,在实验过程中还要注意温度计探头是否移动或掉出,而且麻醉本身就会影响小动物们的体温。当体温计不能直接保存数据的时候,还要一个个记录数据。。。
想想这工作量,可不就让各位师兄师姐们抓头挠耳的吗?头发都愁的掉了一大把,发际线蹭蹭往上移!
当你想要长时间,多频率地连续测量动物体温变化的时候,你是不是感到很头疼,不知道怎么才能得到想要的数据呢?安利一款可多通道、无线式检测体内温度利器——Anipill® 体温胶囊,轻松实现动物体温监测,扫描下方二维码即可试用。
Anipill® 体温胶囊基于使用微型传感器准确测量生理参数,将测得的数据连续无线地发送到便携式设备,允许远程监控。其体积小,无害,高精度,寿命长,可远距离传输等优点不仅解决了传统方式记录体温耗时的问题,还避免了多次重复操作对动物造成压力影响数据收集现象,从而深受客户的喜爱,目前已有较多相关文献发表于 Nature、Elsevier 等诸多 Sci 期刊上(相关文献见文末)。
为什么选择 ANIPILL® ?
操作简单,舒适性强
该解决方案由生理学家参与开发,使产品在舒适性和易用性得到很好地结合:开始启动后,自动采样并传输、保存数据,连接电脑即可查看数据。
采样精确,数据可靠
Anipill® 是一种小型电子胶囊,便于中型物种吞食,也可简单地植入小型动物,如小鼠(起始重量为 20 g),实时通信技术使您能够连续访问从专门的监测仪 Anilogger® 收集的数据,每个胶囊的内嵌存储器确保突发情况下与监测仪的通信中断时可恢复所有其收集的数据,比方说在正常生命状况下的测量期间通信中断,数据同步后可以恢复所有测量的温度值,而不会丢失数据。
多线程操作,更高效
ANIPILL® 胶囊可在启动完成后和 AniLogger® 监测仪的配对,1 台监测仪可同时追踪 8 个胶囊,胶囊的工作时长为 20 天至 10 个月(具体取决于所选的采样周期),确保同时批量完成数据,减少实验成本,此外设备可与 PC 和 MAC 兼容的接口,方便后续对收集数据进行存档或临床操作;
保障动物福祉
尊从保障动物福祉的原则,有效减少对动物进行处理,施加压力和限制条件,保持其团队流动性及生活条件,进一步确保数据可靠性。
应用领域
AniLogger® 解决方案持续监控动物体内温度,目的是为了了解动物的生理机制或监测其发热状态。该设备不但适用于收集药物/疫苗学数据,而且也适用于分析生物节律,休眠或温度调节过程。
➣ 药理学研究:
监测温度对于传染病/病毒传染的研究医治是至关重要的,对温度动力学的分析有助于更好地了解活性物质,医治方法或病理学是如何影响动物调节其体温能力的。
➣ 休眠研究:
休眠是动物的生命功能保持在较差状态的生物条件,这相当于一段冬季的深度睡眠时间。期间,动物经历了一系列生理变化(体温过低,基本功能降低 … )。
➣ 生物节律分析:
体内温度是生物节律的关键指标,对这一变量的持续监测允许对体内温度昼夜节律(分析生物节律和睡眠失调的基本工具)进行表征。
➣ 温度调节机能分析:
温度调节机能学是一个主要的科学轴,重点研究主体对不同的内部或外部刺激的反应。了解其基本机制非常重要,因为它们不仅影响体内和体外温度,也影响其他生理变量,如心率,血压等。

volume 577, pages249–253(2020)
Tracking of body temperature Body temperature was measured using the Anipill remote temperature monitoring system (007894-001, DSI). Adult male mice were implanted with an Anipill capsule in the abdominal cavity. Experiments were carried out more than three weeks after surgery. Mice were singly housed the day before the experiment. Ambient temperature was maintained at 23.5 °C, consistent with the ambient temperature of the vivarium. Body temperature was sampled in 5-min increments. LPS or vehicle injections occurred between 11:00–13:00 for experiments assaying the effects of LPS on body temperature in PBS and MIA offspring.

Anipill transmitter implantation. Body temperature of mice was recorded by using Anipill loggers (1.7 g weight and 8.2 mm diameter, 17.2 mm length) (BodyCap, Paris, France) to obtain temperature data from freely-moving mice.

volume 10, Article number: 20680 (2020)
Methods
All animal procedures were approved by the ACER AWERB of the University of Oxford and performed under a UK Home office license in accordance with all relevant laws and regulations. Five wildtype C57Bl6/J mice were implanted intraperitoneally with anAnipill temperature telemeter. Following post-operative recovery mice were housed at an ambient temperature of 22 ± 1 °C in open-top cages, each positioned under a thermal camera. Tskin was measured every second by storing the temperature of the warmest pixel. Tcore was measured every 30 s by the implanted Anipill.

Cold exposure and norepinephrine tests. For cold exposure challenge, animals were individually placed and acclimatized to CLAMS cages in early daytime with free access to water but no food for at least 6 h at 23 °C. Five days later, animals were placed in pre-cooled CLAMS cages without food access for 6 h at 4 °C. Core body temperature measurements were obtained using Anipill Temperature Implant (Phymep).

Body temperature recordings were performed for ~ 2 months in a separate population of mice implanted intraperitoneally with Anipill temperature data loggers. All measurements were performed in both male and female mice. An extensive description of methodological details is available in the Supporting Information.
