Abstract:
Although noninvasive trachea cannula is a common technique in clinic, this technique is hard to be applied in mice. It is even more difficult to perform the repeated noninvasive trachea cannula on the same mouse due to the throat injury. Here we report an effective, rapid and easy method to perform the noninvasive intubation on mice. This method can effectively be applied to many pharmacological and other related studies. In addition, this strategy can protect the mouse from physical injury caused by operative procedure. All procedures involving animal treatment were approved according to the Committee on the Ethics of Animal Experiments of the Institute of Materia Medica, Chinese Academy of Medical Sciences. In alliance with lung function measurement system, we detected the normal lung function values and presented the lung function development curves of mice of different age. We found that the lung function of mice was matured at 8 weeks old or at the body weight of 18-20 g. In addition, we constructed the mouse model of multiple bleomycin induced pulmonary fibrosis by using this method and illustrated that the trachea cannula is more efficiency than nasal inhalation. Using this method, we have confirmed that the immune microenvironment in lung tissue of multiple bleomycin model is distinct from that of single bleomycin induced pulmonary fibrosis model. Thus, this method is a reliable and safe strategy for the pharmacology study.
