Embodiment

[0022] Codonopsis pilosula and Astragalus membranaceus are removed from impurities and processed into decoction pieces. Accurately weigh 400 grams each of Dangshen Radix Astragali, rinse with deionized water, add 3200ml of deionized water, heat and extract for 1 hour, and release the extract; then add 2400ml of deionized water, heat and extract for 1 hour, and then release the extract; Add 2400ml of deionized water, heat and extract for 0.5 hours, and release the extract. Merge after three extracts are filtered, concentrate to 600ml, then add the ethanol that concentration is 95% to make alcohol content be 60%, precipitate for 24 hours, filter; 80%, precipitated, filtered, recovered ethanol and concentrated to 400g to obtain the Codonopsis and Radix Astragali extract composition.

[0023] The medicine of the present invention can be stored in cold storage with an appropriate amount of ethanol, or stored at room temperature after being dried. In the medicine of the present in...

Abstract

An application of the composition of pilose asiabell root and astragalus root in preparing the medicine for preventing and treating acute lung injury is disclosed.

Description

technical field [0001] The invention relates to the application of a Codonopsis Radix and Astragalus composition in the preparation of medicines for treating acute lung injury. This application is a related application of the patent application CN03123045.8 submitted by the same applicant on April 29, 2003. Background technique [0002] Acute lung injury (ALI) can be caused directly by exogenous stimuli or secondary injury after severe trauma. Although the research on the pathological mechanism of ALI has been very in-depth, the clinical fatality rate of acute respiratory distress syndrome (acute respiratory distress syndrome, ARDS) is still about 50%. [0003] Acute lung injury is the specific manifestation of systemic inflammatory response syndrome and multiple organ dysfunction syndrome in the lung, and is an acute inflammatory response at the level of alveolar capillaries mediated by cells and somatic cells. [0004] Lipopolysaccharide (LPS) is the main component of en...
