Problems solved by technology

Although guinea pig cough detection is very mature, the cost of using guinea pigs for experiments is relatively high. Guinea pigs are delicate and easy to die. Drugs are expensive to screen and it is difficult to conduct multi-group and large-scale research.

Embodiment 1

[0025] 1. Experimental animals and grouping

[0026] SPF grade BALB / c mice, female, 10 weeks old, weighing 22-25g, can freely eat OVA-free feed and three-distilled water. 40 mice were divided into normal saline (NS) group, codeine (CDI) group, capsazepine (CPZ) group, capsasin (Capsasin, CAP) depletion group, 10 in each group . The mice in the CDI group and the CPZ group were given drug pretreatment 2 days before the experiment and on the day of the experiment, a total of 3 times. CDI group mice (100mg / kg) were intragastrically administered codeine 0.2ml / d, and CPZ group mice (6mg / kg) were intraperitoneally injected 0.2ml / d capsicum flat. The NS group was intragastrically administered with normal saline 0.2ml / d, and the experimental procedure was the same as before. The capsaicin depleted group was subcutaneously injected with 50mg / kg, 100mg / kg, 150mg / kg capsaicin 3 days before the experiment, and the total dose reached 300mg / kg. Light anesthesia with pentobarbital sodium ...

Abstract

The invention discloses a method for establishing and detecting a mouse cough model. The method comprises the following steps of: (1), providing a female 22 to 25-gram and 10-week-old Balb / c mouse of SPF animal grade; (2), providing a Buxco noninvasive detection system and putting the mouse in a plethysmogroph to allow the mouse to move freely, wherein the Buxco noninvasive closed plethysmogroph is connected with a sound monitoring device and a signal converter; and (3), stimulating the mouse to cough through atomized capsaicine stimulation liquid, monitoring the cough sound of the mouse in real time, recording sound waves by using sound analysis software, converting airflow change in the plethysmogroph into a respiration waveform by using Finepointe software, recording and automatically analyzing the respiration waveform in real time. The mouse cough sound and the respiration waveform can be simultaneously monitored by the method, so the method has the advantages of greatly reducing work intensity, saving work time, improving work efficiency, and contributing to the popularization and application of the mouse cough model.

Description

technical field [0001] The invention belongs to the field of medical research, in particular to a method for establishing and detecting a mouse cough model. Background technique [0002] Due to the small physiological and anatomical structure, the sound signal is extremely weak, there are few studies and the results are mixed. Whether mice cough or not is still controversial internationally. Indian scholars and Mexican scholars covered the mice stimulated by drugs with a funnel-shaped device, and placed a stethoscope on the top to monitor the voice of the mice, but the results were relatively subjective and could not be recorded and analyzed. In 2002, Wu Kangsong of my country published a method for establishing a mouse cough model, which mainly imitated the detection method of Professor Junzo Kamei of Japan, without any special improvement. Since the 1990s, Professor Kamei has been using the mouse cough model to conduct research on antitussives, and is currently the most w...
