产品描述
塔望动物全身体积描记系统WBP-4MR
气道高反应性(Airway hyperresponsiveness,AHR)、气道炎症和可逆的气道阻塞是支气管哮喘的特征。通过动物模型可研究用于防治气道炎症和AHR的方法和受试药物。传统的方式多采用气管插管,检测气道阻力和肺顺应性来评估动物气道功能的改变。但这些方法有其局限性,如整体试验中麻醉药物的影响,麻醉深浅和麻醉药物对AHR的神经源和气道炎症的影响,实验人员手术操作技术上的要求和耗时,麻醉或手术后动物存活困难不能长期跟踪研究等因素。
无约束全身体积描记法(whole-body plethysmograph,WBP)可以对清醒自由活动的小动物进行肺功能及气道反应相关的测试,避免了创伤性气管切开术及麻醉的影响,在动物处于自然状态下就可以直接测定其气道反应性。而且每次可以同时检测多只动物。整个实验过程简便快捷,并适合长期跟踪研究。
