The specific embodiment:
Pharmaceutical preparation of the present invention can be fast presses down pathogenic microorganism such as killing staphylococcus aureus, bacillus pyocyaneus, mycete, is used for various colpitis such as bacillary, mycotic, gonococcus property, infusorian property, prevention of STD.The inventor cures mainly according to its function, from antiinflammatory, anti-vaginitis, aspect such as antibiotic its pharmacodynamics is verified.
Be subjected to the reagent thing: according to this product preparation that two kinds of preparation methoies of optimal proportion of the present invention make, 1, No. 2 is suppository, and No. 3 is lotion.
FUYANXIAO PAOTENGPIAN: Guangzhou Zhongyi Medicine Industry Co., Ltd produces, lot number: 20030501.
Instrument: PB303-N electronic balance, Mettler-Toledo Instrument (Shanghai) Co., Ltd..
Animal: Kunming mouse 18~22g, male and female dual-purpose; White rabbit male and female half and half, 2.0~2.3kg provides by Shandong University's Experimental Animal Center.
Test 1: to the influence of mice granuloma induced by implantation of cotton pellets
Get 50 of mices, male and female half and half are divided into five groups at random, and each Mus is used etherization, and the otch of a long 0.5cm is cut in back cropping sterilization, respectively implant the sterilization cotton balls of a 5mg from otch to the oxter, both sides, sew up the incision.From continuous subcutaneous administration 7d on the operation same day, mice is put to death in dislocation in the 8th day, cut skin of back, cotton balls is taken out together with granulation tissue on every side, reject fatty tissue, place 60 ℃ of drying baker oven dry, accurately take by weighing weight and write down the result, cause scorching cotton balls weight and deduct cotton balls weight and ask poor, the results are shown in Table 1.
The influence of table 1 pair mice granuloma induced by implantation of cotton pellets (X ± S)
Group | Dosage/ml | Number of animals/only | Granuloma induced by implantation of cotton pellets weight difference/mg |
Blank group this product preparation 1 this product preparation 2 this product preparations 3 positive drug groups | | 10 10 10 10 10 | 7.51±1.78 6.38±1.25* 6.42±1.11* 5.90±0.80* 6.10±0.87* |
Annotate: compare * P<0.05 with matched group, * * P<0.01
Table 1 is the result show, this product preparation 1-3 number has significant inhibitory effect to the mice granuloma induced by implantation of cotton pellets.
Test 2: anti-rabbit bacterial vaginitis test
Get 30 rabbit, be divided into 5 groups after the modeling at random.7d vagina pathological changes situation after the administration of observed and recorded infection animal, vaginal swab smear staining microscopy is got in the local film making of vagina, and rabbit lives and kills, and gets that vagina tissue is fixed, section, HE dyeing, microscopy and film making.The results are shown in Table 2.
The criterion recovery from illness: the vagina outward appearance does not have hyperemia, redness, no purulent secretion, and the vaginal swab smear for microscopic examination loses infectious bacteria and non-viable non-apoptotic cell, and mucosa is complete in the vagina tissue section, submucous tissue is normal substantially.Take a turn for the better: the vagina outward appearance has mild hyperaemia, redness, a small amount of purulent secretion is arranged, the visible a small amount of infectious bacteria of vaginal swab smear for microscopic examination and a small amount of non-viable non-apoptotic cell, the visible vaginal mucosa of tissue slice microscopy has slight damaged, telangiectasis in the submucous tissue, erythrocytosis have a small amount of neutrophil infiltration in the tissue.Invalid: the hyperemia of vagina outward appearance, redness, a large amount of purulent secretions are arranged, and the vaginal swab smear for microscopic examination is seen a large amount of infectious bacterias and non-viable non-apoptotic cell, and the visible mucosa of vagina tissue section microscopy has damaged, a large amount of telangiectasis, erythrocytosis in the submucous tissue has a large amount of neutrophil infiltration.
The anti-rabbit bacterial vaginitis of table 2 result of the test (X ± S)
Group | The recovery from illness number/only | Cure rate (%) | Good revolution/only | Effective percentage (%) |
Model control group this product preparation 1 this product preparation 2 this product preparations 3 positive drug groups | 0 5 4 4 5 | 0 83.33 66.66 66.66 83.33 | 0 1 2 1 1 | 0 100.00 100.00 83.33 100.00 |
The effective percentage of the anti-rabbit bacterial vaginitis of this product preparation is 90.44% as a result, and the rabbit bacterial vaginitis is had significant therapeutic effect.
Test 3: external minimal inhibitory concentration (MIC)
With this product preparation be diluted to 1,0.5,0.25,0.125,0.0625, a series of concentration of 0.03125g/ml, above-mentioned concentration added in the Nutrient medium by 1: 10, the autoclave sterilization sterilization.Each experimental bacteria of preserving is inoculated in the Carnis Bovis seu Bubali cream soup body culture medium growing state on the medicine flat board of 37 ℃ of incubator cultivation 24h taking-up observation variable concentrations respectively.The least concentration that antibacterial does not grow is the MIC of medicine to this antibacterial.The result shows the MIC of this product preparation: bacillus pyocyaneus 100mg/ml, staphylococcus aureus 50mg/ml, Bacillus proteus 50mg/ml.

A. the test of chromatographic condition and system suitability is a filler with octadecylsilane chemically bonded silica; The phosphoric acid solution of acetonitrile-0.1% (83: 17) is a mobile phase; Detect wavelength 254nm.Number of theoretical plate should be not less than 1500 by the emodin peak.
B. emodin is got in the preparation of reference substance solution, the chrysophanol reference substance is an amount of, and accurate the title decides, and adds methanol and makes the solution that every 1ml contains emodin 10 μ g, chrysophanol 20 μ g, promptly.
C. suppository 1g is got in the preparation of need testing solution, and accurate the title decides, and adds 1% sodium hydroxide solution 50ml, boiling water bath refluxed 30 minutes, took out, and put cold, 0 ℃ of cold preservation 30 minutes, filter with absorbent cotton, get subsequent filtrate 25ml, add hydrochloric acid and transfer pH to 7, add hydrochloric acid 2.5ml again, boiling water bath back hydrolysis 1 hour, acid liquid is centrifugal, and (3500 change/min) 15min, inclining supernatant to separatory funnel, residue adds the small amount of methanol dissolving, the a small amount of ether washing container of reuse, methanol solution and washing liquid are all incorporated in the separatory funnel, and the jolting that adds diethyl ether is extracted 5 times, each 25ml, merge ether extracted liquid, use a small amount of anhydrous sodium sulfate dehydration, filter, a small amount of ether washing container of reuse and filter, washing liquid is incorporated in the ether solution, volatilizes ether, residue add methanol make the dissolving and be transferred in the 10ml measuring bottle, add methanol and be diluted to scale, shake up, filter with microporous filter membrane (0.45 μ m), promptly.
D. accurate respectively reference substance solution and each the 10 μ l of need testing solution of drawing of algoscopy inject chromatograph of liquid, measure, promptly.
Every piece of bolt of this composite preparation contains Radix Et Rhizoma Rhei with emodin (C
