Embodiment 3

[0076] Embodiment 3: Chicken chorioallantoic membrane (CAM) test of atractylodes

[0077]The chorioallantoic membrane (CAM) test is one of the widely used models among the alternatives to eye irritation tests. Chicken chorioallantoic membrane is a kind of extracorporeal circulatory system of chicken embryo, which has a complete tissue rich in blood vessels. Using the similar characteristics of CAM and conjunctiva structure, by observing the changes of blood vessels (congestion, bleeding, coagulation) after CAM is exposed to chemical substances ), to detect the damage of chemical substances to CAM, and to evaluate the possible irritation of chemicals.

[0078] In order to further determine the irritation of atractylodes, the stimulation test of atractylodes with different concentrations on the allantoic membrane of chicken embryos was carried out to test the irritation of atractylodes, so as to provide sufficient evidence for the application of atractylodes in external skin pro...

Abstract

The invention discloses the application of atractylodesin in the preparation of inhibitors of Propionibacterium acnes, the chemical formula of atractylodesin is C 13 h 10 O, the chemical name is 1,7-nonadiene-3,5-diyne furan; at the same time, atractylodes can be used to prepare the skin topical Propionibacterium acnes inhibitor, which has a good therapeutic effect on its related diseases, especially acne . The acne propionic acid inhibitor prepared by the atractylodes used in the present invention has the advantages of being safe, non-irritating, and has no side effects, has a certain preventive effect on diseases related to the excessive proliferation of Propionibacterium acnes, and can be widely used in the preparation of acne propionic acid for external use on the skin Bacillus inhibitors and products for the prevention and treatment of related diseases caused by the excessive proliferation of Propionibacterium acnes.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to the application of atractylodes atractylodis in the preparation of medicaments for treating acne. Background technique [0002] Propionibacterium acnes (P.acnes) is a Gram-positive anaerobic short bacterium, an intracellular parasite, which belongs to the normal flora of the skin, and generally resides in the hair follicles or sebaceous glands of the skin. As adolescents mature, horn plugs appear at the hair follicle opening, and the secretion function of the sebaceous glands also increases significantly. Because sebum contains more fatty acids and other components, it is suitable for the growth and reproduction of P.acnes, and the excessive proliferation of Propionibacterium acnes produces an inflammatory response, thus One of the leading causes of acne. [0003] Propionibacterium acnes plays an extremely important role in the formation of acne inflammation. Acne patients wit...
