Abstract

The invention discloses a preparation method of a stasis-phlegm type ovarian cyst animal model. The preparation method comprises the following steps of (1) applying an estradiol benzoate solution to a rat in estrus with the application dose of 1.5ml / 100g once every 5 days for 4 times continuously, wherein the concentration of the estradiol benzoate solution is 3.75 mg / ml; (2) performing intragastric administration with 1ml / 100g high-fat milk once every day for 20 times continuously from the day when the estradiol benzoate solution is applied for the first time, wherein each 100ml of high-fat milk contains the following raw materials by weight: 20g of cholesterol, 3g of sodium cholate, 35g of animal fat, 20ml of propylene glycol, 10ml of tween-80 and the balance being water. The preparation method has the advantage that the stasis-phlegm type ovarian cyst animal model is successfully induced in a manner of combination modeling of subcutaneous injection of estradiol and intragastric administration of high-fat milk; the preparation method has excellent application prospect.

Description

technical field [0001] The invention relates to a method for preparing an animal model of ovarian cyst with mixed phlegm and blood stasis. Background technique [0002] Ovarian cysts (ovarian cysts, OC) refer to the formation of lumps in or on the surface of the ovary. The substance in the lump is usually liquid, sometimes it may be solid, or a mixture of liquid and solid. Ovarian cyst is the most common gynecological disease, which can occur in any female age, especially in women of childbearing age. There are many aspects to the pathogenesis of ovarian cysts. The main reason is that hypothalamic-pituitary-ovarian dysfunction leads to pathological gonadotropin secretion, which affects the production, development, and release of follicles, and eventually forms ovarian cysts. Ovarian cysts belong to the category of "accumulation", "sickness" and "intestinal pain" in traditional Chinese medicine. Its formation is mostly caused by the invasion of six evils, damage of seven emo...
