Abstract
Description
Technical Field
[0001] The invention belongs to the field of biological veterinary medicine preparation, and particularly relates to a method for preparing a medicine for treating bovine cholecystitis. Background Art
[0002] Cholecystitis is a disease that develops in the gallbladder of cattle. When it occurs, the mucous membranes of the eyes turn yellow and the eyelids swell. The cattle become restless and irritable, with noticeable tremors in the front shoulder blades and neck muscles. The animals also experience burning sensations in the mouth, a reddish-yellow mouth, stringy saliva, yellow discharge from the nose, yellow-red mucous membranes at the base of the tongue, dry and constipated stools, and dark yellow urine.
[0003] Niu Changkui proposed the treatment of cattle cholecystitis (bile distension) with the combination of traditional Chinese and western medicine in his paper “Treatment of cattle cholecystitis (bile distension) with the combination of traditional Chinese and western medicine” published in the 4th issue of Animal Husbandry and Veterinary Science and Technology Information in 2012, using injections of western medicines such as atropine, penicillin and analgin for treatment, while using Dahuang Chaihu Decoction composed of traditional Chinese medicines such as Bupleurum, Scutellaria, Shuanghua, Artemisia capillaris, Gardenia, Rhubarb, Corydalis yanhusuo, Curcuma aromatica, Taraxacum mongolicum, Jujube, Citrus aurantium and Gentiana scabra for treatment.
[0004] CN103055060A discloses a compound propolis composition for treating bovine cholecystitis and a preparation method thereof. The composition involved in this invention application is composed of 10 traditional Chinese medicines, including propolis, Artemisia capillaris, rhubarb, dandelion, Lysimachia scabra, Gardenia jasminoides, Alisma orientalis, Terminalia chebula, Sanguisorba officinalis, and Forsythia suspensa.
[0005] In a paper published in the Journal of Animal Science and Veterinary Medicine (January 1994), Kong Xiaoming et al., titled "Pathological Histochemistry and Ultrastructural Studies of Cholecystitis in Yellow Cattle," electron microscopic observations confirmed that when cholecystitis occurs in yellow cattle, not only does the number of glands and glandular cells increase, but the number of rough endoplasmic reticulum and secretory granules in the glandular epithelium also increases significantly. These observations suggest that chronic glandular proliferative cholecystitis in cattle bile is primarily caused by chemical pathogens, physiological factors, and other factors, with no signs of bacterial infection.
[0006] The drugs currently used to treat bovine cholecystitis are mainly chemical drugs or Chinese herbal medicines. The inflammatory reaction of bovine cholecystitis is mostly manifested as chronic glandular proliferative cholecystitis, and some are acute attacks of chronic cholecystitis. Summary of the Invention
[0007] The purpose of the present invention is to solve the problem that the existing drugs for treating bovine cholecystitis are not effective, and to provide a method for preparing the drugs for treating bovine cholecystitis.

Weak ultrasound is used in a buffer solution to activate the activity of various pathogens. During the intelligent cultivation process, the corresponding antimicrobial peptides and antimicrobial proteins are strongly induced in the larvae of the large-headed golden fly. These antimicrobial peptides and antimicrobial proteins have high biological activity and a broad spectrum of action. Clinical treatment results have shown that the drug prepared by the present invention has good therapeutic efficacy and high efficiency. The production process of the present invention is easy to control industrially, the product has good consistency, saves energy, and is suitable for large-scale production.

The liquid is collected and added with solid ammonium sulfate to precipitate and separate the precipitate containing antimicrobial peptides and antimicrobial proteins. The precipitate is then washed with ethanol and distilled water. The purified antimicrobial peptides and antimicrobial proteins are freeze-dried, and the dried antimicrobial peptides and antimicrobial proteins are sterilized at high temperature instantaneously.
