Problems solved by technology

[0003] At present, the most common drugs used clinically are metronidazole (metrodiazole) and antibiotics. Among them, metronidazole has a good effect on trichomonas and anaerobic infection, but the drug is easy to enter the fetus through the placenta, and is harmful to rodents. Animals have carcinogenic effects and also have mutagenic effects on bacteria, so they are harmful to humans or can cause teratogenicity. Pregnant women should use them with caution. Pregnancy is a period of high incidence of vaginal infections. The reason is that cellular immune function declines and estrogen increases The glycogen content in the vaginal epithelium increases, which becomes a medium conducive to the growth of bacteria and accelerates the reproduction of pathogenic bacteria
