Embodiment 1

[0028] In vivo pharmacodynamics study of honeysuckle petroleum ether extract in the treatment of pulmonary fibrosis

[0029] Bleomycin is the most commonly used inducer of pulmonary fibrosis model, which can cause pulmonary fibrosis in a small number of patients in clinical application, and has been used to prepare IPF models of various animals. The medicine of the present invention has therapeutic effect on the C57BL / 6 mouse IPF model animal induced by bleomycin.

[0030] 8-week-old male C57BL / 6 male mice were purchased from Jinan Pengyue Experimental Animal Breeding Co., Ltd. (certificate number: NO.37009200003495); honeysuckle petroleum ether part extract was adopted by the natural medicine laboratory of Shandong University of Traditional Chinese Medicine. Extraction; sodium pentobarbital: Shanghai Chemical Reagent Co., Ltd. of China Pharmaceutical Group, prepared a 2% solution with normal saline and injected intraperitoneally at 2ml / Kg body weight; bleomycin hydrochloride fo...

Abstract

The invention discloses an application of honeysuckle flower extract extracted with petroleum ether to preparation of a pulmonary fibrosis treatment drug, provides a novel application of the honeysuckle flower extract extracted with petroleum ether to pulmonary fibrosis treatment and belongs to the technical field of traditional Chinese medicine treatment of pulmonary fibrosis. The honeysuckle flower extracted with petroleum ether can relieve morphological lesions of lung tissue, reduce lung tissue collagen deposition, reduce content of hydroxyproline in the lung tissue, inhibit fibrosis morphological change of A549 immortalized cell lines sourced from human type-II pulmonary epithelial cells, inhibit type-I collagen gene expression of the A549 immortalized cell lines sourced from the human type-II pulmonary epithelial cells and reduce content of hydroxyproline in the cells. The honeysuckle flower extract extracted with petroleum ether has certain inhibition effect on fibrosis or collagen generation of in-vivo / in-vitro IPF models and is a potential Chinese herb extract for pulmonary fibrosis treatment.

Description

technical field [0001] The invention specifically relates to the application of honeysuckle petroleum ether part extract in the preparation of pulmonary fibrosis medicine, is a new use of honeysuckle extract for treating pulmonary fibrosis, and belongs to the technical field of traditional Chinese medicine for treating pulmonary fibrosis. Background technique [0002] The morbidity and mortality of fibrotic diseases continue to increase, and there are many people with fibrotic diseases. Although the understanding of the process of fibrosis has made significant progress in recent years, the pathogenic factors and pathological mechanisms of fibrotic diseases are still not fully understood. At the same time, most clinical trials have failed, and most fibrotic diseases currently lack effective treatments. . Fibrotic diseases include diseases involving multiple organs or multiple systems, such as lung, liver, kidney, and heart fibrosis, as well as systemic sclerosis, multifocal ...
