Abstract

The invention discloses a traditional Chinese medicine composition for treating piglet yellow-white dysentery and a preparation method thereof, and belongs to the technical field of veterinary traditional Chinese medicine. The traditional Chinese medicine composition is mainly composed of the following traditional Chinese herbals in parts by weight: 100 parts of poplar flower, 9 to 15 parts of coptis, 20 to 40 parts of Chinese pulsatilla root, 15 to 30 parts of purslane, 15 to 30 parts of phellodendron, 15 to 30 parts of ash bark, 15 to 30 parts of andrographis paniculata, and 15 to 30 parts of folium isatidis. The raw materials mentioned above are compounded according to the principle of "monarch, minister, assistant and guide" in the traditional Chinese medicine theory. The Chinese pulsatilla root has a bitter cold property, is capable of entering the blood, is taken as the monarch drug, and has the functions of clearing heat, removing toxicity, cooling the blood, and stopping the dysentery. The coptis has a bitter cold property, has the functions of purging fire, removing toxicity, drying dampness, and protecting intestines, and is an effective drug for treating dysentery; the phellodendron has the function of clearing dampness and heat in lower jiao, and the coptis and phellodendron are taken as the minister drugs to assist the monarch drug to exert the functions of clearing heat and removing toxicity, especially the functions of drying dampness and stopping dysentery. Ash bark, andrographis paniculata, poplar flower, purslane, folium isatidis have a bitter taste and a cold property, have the functions of clearing heat, removing toxicity, inducing astringency, and stopping dysentery, and are taken as the assistant and guide drugs. The drugs mentioned above cooperate with each other to generate the functions of clearing heat, removing toxicity, cooling the blood, and stopping dysentery, and the traditional Chinese medicine composition is mainly used to treat piglet yellow-white dysentery.

Description

A kind of Chinese medicine composition being used for the treatment of yellow and white dysentery of piglet and preparation method thereof
Technical field

Test example
1, trial drug: the solution that test group adopts embodiment 1 ~ 3 to prepare, matched group adopts commercially available enrofloxacin soluble powder, is provided by Zhengzhou Houyi Pharmaceutical Co., Ltd., and product batch number is: 20110110.
2, Antigen isolation and identification: gather feces from the frank sick pig rectum of Hakuri with disinfecting silk or cotton swab, be inoculated on Mai Kangkai flat board, cultivate 24 ~ 48h, the brick-red bacterium colony that picking is smooth for 37 DEG C, after several separation and purification, be inoculated on ordinary broth culture fluid and nutrient agar panel.Picking pure culture smear, microscopy, and carry out biochemical test and mice Virulence detection.
3, the external mattress that presses down is tested
(1) extracorporeal bacteria inhibitor test of Chinese medicine: punch on the agar culture medium being coated with pathogen, and it is a little to add the sterilizing agar dissolved at the bottom of hole, to seal at the bottom of hole, solution prepared by embodiment 1 ~ 3 is added respectively in hole, be advisable to fill it up with not overflow, put after cultivating 24h in 37 DEG C of incubators, measure antibacterial circle diameter.
(2) drug sensitive test of antimicrobial drug: select enrofloxacin, ciprofloxacin, ceftazidime, rifampicin, cephazolin, furazolidone, ampicillin, ceftriaxone sodium, spectinomycin, norfloxacin to carry out drug sensitive test.
Criterion: antibacterial circle diameter≤10mm is drug resistance; L0 ~ 15mm is medium sensitivity; >=15mm, for extremely sensitive.
4, test method
Experimental animal: choose 10 ~ 30 age in days generation Hakuri and the obvious piglet of clinical symptoms 400, according to the principle that disease time, age in days, severity extent, body condition are relatively consistent, adopt the method for grouping in nest, the piglet suffering from Hakuri is divided into 4 groups at random, often organize 100.Test group 1 ~ 3 gavages solution prepared by embodiment 1 ~ 3, and every each 10ml, every day 2 times, is used in conjunction 3 days; Matched group adopts commercially available pig specific drug enrofloxacin soluble powder to treat, and every pig 1.2g, is dissolved in 5ml warm water and gavages, and every day 2 times, is used in conjunction 3 days.
Curative effect determinate standard:
Cure: after testing 1 course for the treatment of of disease pig medication, feces, spirit, appetite recover normal;
Effective: after testing 1 course for the treatment of of disease pig medication, pellet morphology takes a turn for the better, and number of times of having loose bowels reduces, and appetite takes a turn for the better;
Invalid: after testing 1 course for the treatment of of disease pig medication, symptom is not improved, even to increase the weight of or dead.
5, date processing: the significance test carrying out data with statistical method, cure rate, total effective rate X 2 test.
6, result of the test
(1) Antigen isolation and identification
Through test for identification, the antibacterial be separated to from morbidity piglet feces is pathogenic colon bacillus.
(2) extracorporeal bacteria inhibitor test of Chinese medicine
The diameter that embodiment 1 ~ 3 prepares the inhibition zone of solution is respectively 12.0mm, 12.7mm and 11.5mm, and establishing criteria is judged to be medium sensitivity.Result of the test shows that By Chinese Medicines agent of the present invention has certain inhibitory action to colon bacillus.
(3) drug sensitive test of antimicrobial drug
As can be seen from Table 1, enrofloxacin, ceftriaxone sodium, ring receives the third husky star, cephazolin is Gao Min; Ceftazidime, ampicillin, spectinomycin, norfloxacin are quick in being; Rifampicin is drug resistance.Therefore select enrofloxacin medicine as a control group.
Table 1 antibacterials are to the fungistatic effect being separated Enteropathogenic Escherichia coli
(4) Chinese medicine is to the therapeutic effect of yellow and white dysentery of piglet
As can be seen from Table 2, the total effective rate of test group reaches more than 95%.Statistical analysis shows, the cure rate of test group is significantly higher than matched group (P < 0.01), without significant difference (P > 0.05) between total effective rate.Also without significant difference (P > 0.05) between the total effective rate of test group 1 ~ 3.
The each processed group of table 2 is to the therapeutic effect of yellow and white dysentery of piglet
Discuss:
Piglet pujos blancos is primarily of caused by pathogenic colon bacillus, and the source of infection normally carries disease germs sow.Pathogenic colon bacillus, after sow excretes, intersperses among colony house, pollutes the nipple of sow and skin, and piglet is sucked the breast or when licking sow skin, The book of Changes oral cavity infection.The In Vitro Bacteriostasis result that embodiment 1 ~ 3 prepares solution shows, Chinese medicine of the present invention has certain inhibitory action to pathogenic colon bacillus.From fungistatic effect, the cure rate of test group 1 ~ 3 is apparently higher than enrofloxacin (P < 0.01), and enrofloxacin easily produces resistant strains.Result of the test also shows, Chinese herbal and crude drugs preparations, except having antibacterial action, also by other approach, such as resists the enterotoxin that colon bacillus produces, with the mucoprotein formation protecting film in intestinal mucosa surface, and the physiological function etc. of adjustment biological organs.
