Abstract

The invention relates to the technical field of medicines, and in particular relates to application of a lalang grass rhizome ethyl acetate part extract in preparation of a medicine for relaxing pre-contracted tracheal smooth muscles. By detecting the tension of the isolated tracheal ring muscle of an experimental mouse, it is found that the lalang grass rhizome ethyl acetate part extract has theeffect of efficiently relaxing abnormally contracted tracheal smooth muscles; and it is indicated that the lalang grass rhizome ethyl acetate part extract is expected to be applied to relieving asthma. A basis is provided for developing the application of the lalang grass rhizome ethyl acetate part extract in preparation of the medicine for relaxing the pre-contracted tracheal smooth muscles.

Description

technical field

[0001] The invention relates to the technical field of medicine, in particular to the application of the extract of ethyl acetate part of Rhizoma Imperatae in preparing medicine for relaxing and pre-contracting tracheal smooth muscle. Background technique

[0002] Bronchial asthma, referred to as asthma for short, is a chronic airway disease characterized by reversible bronchoconstriction, mucus hyperplasia, and airway hyperresponsiveness. The pathogenesis of asthma is very complex and varies from person to person, such as ion channel lesions, immune system disorders, genetic abnormalities, inflammatory responses, and changes in respiratory structure. Currently, clinically used drugs for the treatment of asthma can be roughly divided into two categories, mainly including symptom-controlling drugs and symptom-relieving drugs. Such as theophylline drugs, leukotriene regulators and Ξ²2 receptor agonists. However, long-term use of the above-mentioned drugs will ...
