Medication: after the mouse vagina dysbacteriosis model modeling success; Inject each 50 μ L of prescription high dose group (crude drug content 1g/ml), low dose group (crude drug content 0.25g/ml) and JIEERYIN group (JIEERYIN medicinal liquid dilution 50%) for the model mice intravaginal; Continuous 7d, every day 1 time.Normal control group and model group each normal saline that injects equal volume every day.
The mensuration of mouse vagina lactobacillus and analysis: behind the last administration 12h, get 50 μ L normal saline with micro sample adding appliance, wash mouse vagina repeatedly 8 times, 10 times of serial dilutions of vaginal washing fluid of getting 30 μ L are to 10-6.Drip kind on the MRS selective medium with micro sample adding appliance, carry out count plate (CFU/mL) (testing repetition 3 times) after cultivating through 37 ℃, 48h.
3 experimental results
Through setting up antibiotic induced mouse vagina dysbacteriosis model; Use the lactobacillus in the mouse vagina secretions of back to measure with the method for plate culture count to prescription, the result sees table 11: respectively organize mouse vagina lactobacillus testing result (viable count CFU/mL) after the medication.
