Abstract
The invention discloses an application of tetrastlgma hemsleyanum in preparing a drug for treating livestock viral infectious diseases. According to the application, tetrastlgma hemsleyanum is used for treating livestock viral infectious diseases, particularly Newcastle disease, infectious bursal disease virus, avian infectious broncheitis, porcine reproductive and respiratory syndrome and porcine circovirus mixed infection; and the drug has a high curative effect and small side effects, and a new choice is provided for clinically treating livestock viral infectious diseases.
Description
Technical field
The invention belongs to the field of Chinese medicines, be specifically related to the application in the medicine of preparation treatment livestock and poultry virus sexually transmitted disease of Radix Tetrastigmatis Hemsleyani and extract thereof.
Background technology
Along with socioeconomic development, people are more and more higher to the prescription of animal products, and poultry infectious disease is very large to aquaculture harm.For viral infectious, antibiotic, sulfa drugs are without therapeutical effect, although the minority medicines such as amantadine, ribavirin, acyclovir have certain curative effect, antiviral spectrum is narrow, toxic and side effects is large, price is high and easily produce drug resistance strain.Therefore, seek novel antiviral medicine extremely urgent.
Radix Tetrastigmatis Hemsleyani is again Radix Apioris Fortunei (Radix Lespedezae Buergeri), is the tuber of vitaceae tetratigma hemsleyanum Tetrastigma hemsleyanum Diels et Gilg, the green herbaceous species of perennation.Originate in the ground such as Zhejiang, Jiangxi, Hunan, Hubei, Fujian, Guangdong, Guangxi and Yunnan, there is the effect of heat-clearing and toxic substances removing, expelling wind and activating blood circulation.Be usually used in the cards such as hyperpyrexia convulsion, pneumonia, cough with asthma, hepatitis, nephritis, rheumatic arthralgia, traumatic injury, carbuncle furuncle furuncle, be also improved the effect of Immune Function.
So far, there is not yet the report of Radix Tetrastigmatis Hemsleyani control livestock and poultry virus sexually transmitted disease.
Summary of the invention
Technical problem to be solved by this invention is to provide the application of Radix Tetrastigmatis Hemsleyani in the medicine of preparation treatment livestock and poultry virus sexually transmitted disease.
Technical problem of the present invention is implemented by the following technical programs:
Radix Tetrastigmatis Hemsleyani is applied in the medicine of preparation treatment livestock and poultry virus sexually transmitted disease, and described livestock and poultry virus sexually transmitted disease can be newcastle disease, chicken bursal disease, infectious bronchitis of chicken, pig blue-ear disease and porcine circovirus mixed infection.Aforementioned Radix Tetrastigmatis Hemsleyani not only refers to Radix Tetrastigmatis Hemsleyani raw medicinal herbs itself, also comprise Radix Tetrastigmatis Hemsleyani processed product, Radix Tetrastigmatis Hemsleyani extract, the preparation that the preparation that the Radix Tetrastigmatis Hemsleyani of take is active component or the Radix Tetrastigmatis Hemsleyani of take are one of active component, is preferably Radix Tetrastigmatis Hemsleyani extract or take the preparation that Radix Tetrastigmatis Hemsleyani is active component.
Radix Tetrastigmatis Hemsleyani extract of the present invention is Radix Tetrastigmatis Hemsleyani water or extractive with organic solvent, can adopt the routine techniquess such as carbon dioxide supercritical extraction method, percolation, decoction, reflux to extract the extract obtaining.Described organic solvent refers to the solvent of the opposed polarities such as ethanol, methanol, and preferably adopting mass percent concentration is 75%～85% ethanol or methanol.
Water extract is preferably prepared as follows and obtains:
Get Radix Tetrastigmatis Hemsleyani, after soaking, decoct 1 ~ 4 time by 5～20 times of medical material weight, each 1 ~ 3h, merges decoction liquor, and dehydration is concentrated into thick paste shape dries and obtain Radix Tetrastigmatis Hemsleyani extract.
Extractive with organic solvent is preferably prepared as follows and obtains:
Get Radix Tetrastigmatis Hemsleyani, pulverize, by 75%～85% ethanol of 5～20 times of weight of medical material weight or methanol (mass percent concentration), soak after 1 ~ 4 hour, percolation, reclaims ethanol or methanol, is concentrated into thick paste shape, and low-temperature reduced-pressure is dried, and obtains extract.
Radix Tetrastigmatis Hemsleyani raw medicinal herbs or its extract can directly be pulverized and make powder, or add pharmaceutically acceptable adjuvant to adopt conventional method to make oral formulations or injection.Described oral formulations is preferably mixture, tablet or oral liquid.
Medium domestic animal (as pig, sheep etc.) is 5～12g each serving amount to raw medicinal herbs with Radix Tetrastigmatis Hemsleyani, and day takes twice, and poultry consumption is 1/10～1/5 of medium domestic animal.
Beneficial effect of the present invention: inventor is with livestock and poultry virus sexually transmitted diseases such as Radix Tetrastigmatis Hemsleyani or its extract for treating newcastle disease, chicken bursal disease, infectious bronchitis of chicken, porcine pseudorabies, pig blue-ear disease and porcine circovirus mixed infections, and curative effect is really stable.The invention provides Radix Tetrastigmatis Hemsleyani for the preparation of the application in the medicine for the treatment of livestock and poultry virus sexually transmitted disease, for clinical treatment livestock and poultry virus sexually transmitted disease provides a kind of new selection.
