Nano silver technology
Silver has generally been recognized for its antibacterial effect, and this is due to its oxygen therapeutic action blocking the bacterial cell wall and blocking bacterial DNA replication for its bactericidal actions. different creatures. In general, an antibiotic can kill 6 different types of bacteria, but silver can kill 600 different types of bacteria.
Silver is also a non-toxic material for tools, so the application range of silver is quite wide and has a long history. See through the high-tech nanotechnology mode, making silver particles is working to become big, antibacterial function is enhanced, and the quality of home environment and Personal Hygiene is increased significantly.
Nano silver solution containing nano-sized fine particles and dissociated silver ions have significant bactericidal effect. Nano silver all have 99.99% inhibitory effect on escherichia coli, staphylococcus aureus, Salmonella and bacillus pyocyaneus, etc. under multiple dilution conditions.
Or can strongly attract proteic sulfydryl in the bacterial body, rapidly combine with it to reduce the enzymatic activity of antibacterial protozoa, thus producing antibacterial effect; By the slow release of silver ions, it is possible to exert a persistent antibacterial effect.
Vaginitis and cervicitis are reproductive tract infections in women with a higher incidence, and the physical and mental health of women and their relatives are significantly affected. Although there are many therapeutic products on the market, all are undesirable in terms of dosage form, method of use, therapeutic effect.
Colitis is caused by bacteria, mycete, chlamydia, mycoplasma, virus, protozoon … The source of infection from the vagina can go up to the uterine cavity, fallopian tubes, ovaries and pelvic cavity, thereby causing endometritis. endometriosis, salpingitis, salpingitis or pelvic infection of the person with acute and chronic, and chronic infection can even cause bowel obstruction and infertility except for the inflammatory symptom.

5. Criteria for evaluating effectiveness
(a) vaginitis (including unilateral vaginitis and trigeminal vaginitis)
Recovery from illness: symptoms and signs disappear, and lymphadenopathy decreases, female sex laboratory test for lymphedema;
Reproductive efficiency: symptoms and signs are clearly better, not completely blind as yet, female sex test lymphatic lab;
Take a turn for the better: symptoms and signs abate, lymphatic lab positive (given invalid statistics);
Invalid: symptoms and signs do not improve, laboratory lymphatic test is positive.
(b) bacterial vaginosis
Post-disease recovery: symptoms and signs disappear, vaginal discharge has a pH value of ＜ 4.5, and female sex amino acids do not show clue cells (clue cells);
Reproductive effect: symptoms and signs are clearly better but not completely resolved, and vaginal discharge pH value ＜ 4.5 or female sex amine test shows no cytological clues;
Take a turn for the better: symptoms and signs alleviate to some extent, pH value of vaginal secretions ＜ 4.5 or test for female sex amines, scent receptor cells ( renders the statistic invalid);
Invalid: symptoms and signs, laboratory tests of vaginal discharge, no obvious improvement.
The effectiveness percentage of cervicitis was calculated: percentage of effectiveness = (cure + effectiveness) / number of conventional treatments * 100%.
(c) cervical abrasion
Post-disease recovery: the symptoms and signs disappear, and the rot to the corn side disappears, and the cervical cervix is smooth;
Production efficiency: clearly better symptoms and signs, no complete wilt, rot to 1/2 corn area, moderate to heavy, moderate to light;
Efficacy: symptoms and signs move to a better stage, not completely resolved and rot to and and 1/2 , or mastoid process is converted to granules, granules are converted simple form;
Invalid: symptoms and signs do not improve, rot to corn area unchanged.
Effective percentage = (cure + effect + effect) / number of usual treatments * 100%.
(d) react inappropriately
Attention should be paid to non-standard reactions during treatment, and to non-standard reactions that have been profiled.
In 47 cases of periodical vaginitis, 38 cases were cured, the cure rate was 80.9%; 7 regular production efficiency, total efficiency rate 95.7%, see table 1 for details.
