Embodiment 1

[0045] Example 1 Protective Effect on Rat Gastric Mucosa Injury

[0046] 1. Experimental purpose: To observe the protective effect of rhein, levocarnitine and rhein + levocarnitine in different dosage ratios on gastric mucosal injury in rats.

[0047] 2. Experimental method:

[0048] 2.1 Model preparation and testing indicators

[0049] Male SD rats were randomly divided into groups according to body weight, and the corresponding doses were given by intragastric administration for 7 days respectively, and the volume of administration was 1ml / 100g body weight. One hour later, intragastric administration of 65% ethanol was administered (administration volume: 4ml / 1000g body weight); one hour after modeling, the animal was sacrificed, the abdominal cavity was opened, the cardia was ligated, and 10ml of 4% formaldehyde solution was injected into the stomach from the pylorus, and ligated quickly Pylorus, the whole stomach was taken out, fixed in the same concentration of formalde...

Description

technical field [0001] The present invention relates to the field of medicine, in particular to a pharmaceutical composition and its pharmaceutical preparation and application. technical background [0002] Mucosal tissue is a membranous structure composed of epithelial tissue rich in secretory glands and small cell vascular network, located in the body cavity, such as the digestive tract (including oral cavity, gastrointestinal tract, esophagus, colon, etc.), nasal cavity, respiratory tract and reproductive system . The oral and gastrointestinal mucosa acts as an important protective barrier against the invasion of microorganisms and pathogens [0003] Mucosa tissues in the digestive tract (including oral cavity and gastrointestinal tract) are always exposed to very harsh environments, for example, corroded by irritants such as strong acids (such as hydrochloric acid), alcohol, and digestive enzymes. Mucous membrane damage in the digestive tract can cause discomfort to th...
