Description

Traditional Chinese medicine composition, antibacterial spray and preparation method

Technical Field

The invention relates to the field of personal care and medical supplies, in particular to a traditional Chinese medicine composition, an antibacterial spray and a preparation method thereof.

Background

Candida vulvovaginitis is a common and frequently-occurring disease of gynecology and is mainly caused by candida albicans, and clinically mainly appears as pruritus vulvae, burning sensation, increased leucorrhea, thickened leucorrhea which is in a curd or bean curd residue shape, and can also be accompanied with frequent urination, painful urination and dyspareunia. This is one of the most commonly affected diseases in adult females and belongs to the categories of "under-the-belt" and "pruritus vulvae" in TCM.

In recent years, reproductive health of men and women has become a focus of public attention, and various gynecological antibacterial products are developed in the market successively, and are popular with consumers. In order to seek out medicines with quick effect, small irritation and small side effect, researchers have carried out a great deal of research on the medicines, but the single use of Chinese herbal medicines mostly cannot achieve very high curative effect and has recurrent problems.

The inventor discovers that a traditional Chinese medicine composition has good antibacterial and bactericidal performance through researches in recent years, and can improve the curative effect, reduce side effects, consolidate the curative effect and reduce relapse through combining the traditional Chinese medicine and western medicine with antifungal medicines to treat candida vulvovaginitis.

Application example 2 vaginal mucosa irritation test of antibacterial spray

The experimental method comprises the following steps: selecting 35 female white rabbits which are healthy, adult and unmatched, dividing the experimental animals into 7 groups, namely 1 blank control group, 1 negative control group and 5 experimental groups, wherein each group comprises 5 animals; the rabbit vaginal orifice was checked prior to dosing for secretion, congestion, edema and other damage. The rabbits were fixed on the bottom to expose the perineum and the vaginal orifice, the hose was gently inserted into the vagina after wetting, 1.5ml of the antibacterial spray obtained in the corresponding examples 4 to 6 and comparative examples 6 to 7 was slowly injected into the test group by a syringe, the catheter was withdrawn after the completion of the administration, and the administration was repeated once every 24 hours for 7 days. The negative control group was treated with physiological saline as well, and the blank group was not treated at all. 24 hours after the last administration, animals are sacrificed, the complete vagina is taken out by laparotomy, longitudinal incision is carried out, and whether congestion, edema and the like appear is observed visually for reference when pathological materials are obtained. Then the vagina is put into 10% formalin solution for fixation for more than 24 hours, tissue sections of the two ends and the center of the vagina are selected, and after HE staining, histopathological examination is carried out.

Through observation of the experimental rabbits in each group, the experimental rabbits in each group have good general conditions, clean hair color, free movement, normal diet, weight increase, no abnormal secretion in vaginal mucosa, and no symptoms such as congestion, edema, necrosis and the like during the administration period. Pathological examination shows that the morphology of the vaginal mucosa epithelial cells of the rabbits in the blank control group is not abnormal, the blood vessel expansion is not seen, the leucocyte infiltration is not seen in the myometrium and adventitia layers, and the blood vessel congestion is not seen. The vaginal mucosa epithelial cells of the rabbits in the negative control group and the experimental group are slightly damaged, and the myometrium and the adventitia are infiltrated with a small amount of white blood cells, but the phenomena of inflammatory cell infiltration and tissue cell necrosis are avoided, and the phenomenon of drug stimulation reaction is eliminated. The antibacterial spray obtained in examples 4-6 and comparative examples 6-7 has no irritation to the complete vaginal mucosa group and the damaged vaginal mucosa group of rabbits.

Application example 3 observation of curative effect of antibacterial spray for treating mycotic vaginitis

Experimental grouping: 216 patients suffering from colpitis mycotica, which are married or sexual women (except pregnant women) with the age of 25-41 years, are selected and divided into 3 treatment groups and 1 control group, wherein 60 patients in each treatment group and 36 patients in the control group; the antibacterial spray obtained in example 4, comparative example 6 and comparative example 7 was used for 3 patients in the treatment group, and clotrimazole suppository (each containing 150mg of clotrimazole in Guangzhou He Ji metric pharmaceutical factory) was used in the control group;

the experimental method comprises the following steps: after washing the vulva and vagina with 2% -3% sodium bicarbonate solution, the vagina is widened by a vaginal device, and the corresponding medicament (the antibacterial spray obtained in example 4, comparative example 6 and comparative example 7) is uniformly sprayed into the vagina, 3-5 sprays/each time, 1 time a day. After the control group irrigated the vulva and vagina, clotrimazole was embolized into the deep vagina, 1 granule each time, 1 time per night. 4. Group patients all need to receive treatment for 7 days.

After treatment, the clinical results of patients are observed, and the curative effect standard is as follows: the external appearance of the leucorrhea is normal after healing, the vaginal congestion disappears, the symptoms of pruritus vulvae, burning pain and urgent urination pain are eliminated, the vaginal secretion is checked to turn into the mold and the cleanliness is I-II degrees after stopping the medicine, and the mold is still negative after checking the vaginal secretion after the next menstrual period.

Effective leucorrhea is reduced, all accompanying symptoms are relieved, vaginal secretion is checked to turn mold into yin 5 days after stopping medicine, but the patient recurs after the next menstrual period.

The leucorrhea is abnormal in appearance, the leucorrhea amount is still as much as bean dregs or curd shape, the symptoms are not improved, and the vaginal secretion is checked to be positive after 5 days of stopping the medicine. The observation results are shown in Table 3.
