Taking Wistar rats, each half of male and female, randomly dividing the Wistar rats into 6 groups, each group comprises 10 rats, and preparing the traditional Chinese medicine composition prepared in the embodiment 4 into three different dosage specifications of high, medium and low according to dosage, wherein the high dosage group comprises 4g/kg, the medium dosage group comprises 2g/kg, the low dosage group comprises 1g/kg, and the positive control group is given with detoxifying acne pills with dosage of 2g/kg, the blank control group and the auricular acne model group with equal volume of physiological saline every day.
The administration is performed by gavage 1 time daily for 10 days. On the 5 th day after each group of rats started gavage, 50uL of sterile normal saline was injected into the left auricle of the blank control group, and 50uL of propionibacterium solution was injected into the left auricle of the other groups (Propionibacterium stock solution: lyophilized Propionibacterium, after being enriched with sodium thioglycollate liquid medium under anaerobic conditions, was washed with normal saline for 3 times, and the concentration of Propionibacterium was adjusted to 6000 trill mL-1And inactivating in water bath at 95 ℃ for 15min for later use). After injection of the prepared model, the thickness of the auricle of the rat was measured with a micrometer every 24 hours for 5 times continuously. The swelling rate of auricles of each mouse was calculated by the following formula:
auricle swelling rate ═ thickness of auricle after injection-thickness of auricle before injection)/thickness of auricle before injection × 100%
After further dosing to 12 days, rat ears were excised, fixed with 10% formaldehyde, sections embedded in paraffin, HE purple, and observed under light.
3. Results
The traditional Chinese medicine composition and the detoxifying acne pill can reduce the auricle swelling rate of rats, but have more obvious effect when the traditional Chinese medicine composition is used in high and medium doses. The results are shown in Table 5.
