Abstract:

Steroids are the main drugs currently used to treat asthma. However, the toxic and side effects of these drugs and the tolerance of the drugs due to long-term administration are still problems in the clinical treatment of asthma. Bavachinin has a good effect in the treatment of mouse asthma models, and it can effectively inhibit the expression of a variety of cytokines. However, it is extremely difficult to dissolve in water, has low bioavailability, and is quickly cleared in the blood. These characteristics limit its clinical application potential. In this study, nanotechnology was used to construct an effective oral drug delivery system. Through analysis of serum-related antibodies and cytokines, the system showed significant therapeutic effects on asthma-positive groups. Far-infrared imaging results showed that the system has a good targeted enrichment effect on pathological parts, while showing lower toxicity and higher therapeutic effect. Whether it is the splenocyte flow typing or the analysis of lung tissue, the system has verified the excellent treatment, and through the observation of paraffin sections of lung tissue, it was found that the bronchial morphology returned to normal after drug treatment, and the leakage of inflammatory cells was significantly reduced.
