凝血酶對(duì)哮喘大鼠氣道炎癥作用的研究
[Abstract]:objective
Bronchial asthma is a common respiratory disease in childhood. Asthma can cause recurrent symptoms such as wheezing, air urgency, chest tightness, or coughing, which bring great pain and heavy financial burden to the patients..IL-6 is an inflammatory factor involved in asthma and plays an important role in the airway inflammation of asthma. Thrombin, a medium for respiratory inflammation, can mediate the activation of NF- kappa B of the proinflammatory transcription factor. In this experiment, thrombin and thrombin inhibitors were given to establish a standard rat model of asthma. The activity of thrombin in alveolar lavage fluid (BALF) was detected by ELISA. (2) the lung group of rats in each group was observed by HE staining. The expression of interleukin (IL-6) protein in lung tissues of each group was detected by immunohistochemistry; (4) the expression of nuclear factor kappa B (Nuclear factor kappa B, NF- kappa B) in lung tissues of rats in each group was detected by immunohistochemical method. The effect of thrombin on airway inflammation in asthmatic rats was investigated. To explore the pathogenesis of airway inflammation in asthma provides new ideas.
Method
24 adult female rats were randomly divided into 4 groups, the normal control group (group N), the asthma model group (group A) thrombin group (group T), the thrombin inhibitor group (group H), 6 rats in each group. The rat model of asthma was prepared with ovalbumin (OVA) sensitization and inhalation excitation. The experimental group (group A, T group, H group) was subcutaneously injected with OVA suspension 1ml on the inside of each thigh on day 1,8, respectively. (OVA10mg+ aluminum hydroxide 200mg+0.9% to 1ml), and intraperitoneal injection of pertussis pertussis suspension 1ml (about 6 x 109 strains) as adjuvant. The 402 ultrasonic nebulizer (Shanghai four medical device factory) was used to atomization of rats in a closed plexiglass container for 30 minutes each time and 3 per week for fifteenth days. Every rat in group T was given inhalation of thrombin 72u for 6 weeks. Each rats in group T were given inhalation of thrombin 72u before each atomization. Each rat in group H was given inhalation of thrombin inhibitor - hirudin 500u/kg. in the normal control group. All the rats were treated with normal saline instead of OVA.. The rat lung tissue and BALF. were taken to determine the thrombin activity in BALF by ELISA method. The inflammatory infiltration of lung tissue was observed by HE staining. The expression of IL-6 in lung tissue was detected by immunohistochemical method, and the expression of NF- kappa B protein in lung tissues of each group was measured by Western blot method.
Result
1. general situation observation
The rats in the experimental group (group A, group T, group H) showed the loss of luster in the rat hair. In the process of stimulating the model, there were different degrees of cough, sneezing, shortness of breath, abdominal muscle tension, limp limbs, slow action, slow reaction and so on. The normal control group had no symptoms.
2. thrombin activity
The thrombin activity in the BALF of the asthmatic group was higher than that in the normal control group (P0.05), and the thrombin activity in the thrombin group was higher than that in the asthma group (P0.05), and the thrombin activity in the thrombin inhibitor group was lower than that of the thrombin group (P0.05).
3. observation of inflammatory infiltration of lung tissue
HE staining showed no inflammatory infiltration in the airway of the normal control group. There were inflammatory cells in the airway of the asthmatic group, and a large number of inflammatory cells were infiltrated in the thrombin group. The inflammatory cell infiltration in the thrombin inhibitor group was less obvious than that in the asthma group.
4. Detection of IL-6 expression in lung tissue by immunohistochemistry
In the normal control group, the expression of IL-6 in the lung tissue was not expressed in the normal control group; the expression of IL-6 in the asthma group was more than that in the normal control group; the expression of IL-6 in the thrombin group was most, higher than that in the asthma group, and the expression of IL-6 in the thrombin inhibitor group was significantly lower than that in the thrombin group.
The expression of NF- kappa B protein in 5. lung tissues was detected by Western blot method. The results showed that the expression of NF- kappa B in the normal control group was weak, the expression of NF- kappa B in the asthmatic group was higher than that in the normal control group. The expression level of NF- kappa B in the thrombin group was the highest, and the expression level of the thrombin inhibitor group was lower than that of the thrombin group.
conclusion
The 1. rat model of bronchial asthma was established successfully.
2. The airway thrombin activity in asthmatic rats increased, and thrombin could promote the airway inflammatory cell infiltration in asthmatic rats.
3. Thrombin can promote the expression of NF-kappa B in the airway of asthmatic rats, and then promote the expression of inflammatory factor L-6, thus participate in the occurrence of asthmatic inflammation.
