Objectives : US extract is a mixture of each extract of Ulmi cortex and Smilacis rhizoma. In this study, we investigated the antioxidant, anti-inflammatory, antibacterial, and ovoprotective effects of US extract in in vitro model to identify potential candidates for improving female reproductive function. Methods : The antioxidant activity of US extract was measured using 1,1-diphenyl- 2-picrylhydrazyl free radical and superoxide anion radical scavenging assays. The anti-inflammatory effect of US extract on lipopolysaccharide (LPS)-stimulated RAW 264.7 cells were determined with a nitric oxide (NO) assay, enzyme linked immunosorbent assays, and western blots analysis. The antibacterial activity of US extract against vaginitis infection microorganisms were determined with disc diffusion and minimum inhibitory concentration assays. The ovoprotective effect of US extract on 4-vinylcyclohexene diepoxide (VCD)-induced ovotoxicity in CHO-K1 cells were evaluated with a cell viability assay. Result : US extract showed good antioxidant capacity and inhibited LPS-induced NO production as well as iNOS and COX-2 expression and secretion of pro-inflammatory cytokine IL-6 without affecting the cell viability. It showed significant clear zones for Staphylococcus aureus and Candida albicans but did not indicate the clear zones for Escherichia coli and Enterococcus faecium. VCD-induced ovotoxicity in CHO-K1 cells was significantly reduced by US extract pre-treatment. Conclusions : These results demonstrate that US extract has antioxidant activity, anti-inflammatory effects on the LPS-stimulated macrophages, antibacterial activity against vaginitis infection microorganisms, and protective effects on the ovarian cells against VCD-induced ovotoxicity. These findings suggest that the US extract can be used as new prescriptions, supplements, functional foods, and cosmetics for improving female reproductive function.

The evaluation of functional active ingredients and dyeing effect on cotton fabric using 16 types of natural products water extracts and 50% ethanol extracts, there were differences in color intensity, but 6 types of red, 5 types of yellow, 2 types of orange, and 3 types of green were observed. In general, the color of the 50% ethanol extract was high and clear. As a result of dyeing by immersing cotton gauze in water extracts and 50% ethanol extracts of these natural products for 2 days, the dyeing effect was generally good, and it was observed that there was little fading decrease in color even after drying at room temperature and opening and storing. The pH of the water extracts of 16 natural products ranged from neutral to slightly acidic, with no side effects on the skin. For DPPH free radical inhibition antioxidant effect, the effect of 50% ethanol extract for each sample was better than that of water extract. As for the polyphenol content, the content of the 50% ethanol extract tended to be higher than that of the water extract. Therefore, the purpose of this study was to investigate the correlation between the antioxidant activity of 16 natural extracts and the prevention of female vaginitis.

Vaginal microbiome deeply influences vaginal health via production of messenger molecules. The healthy vaginal pH ranges between 3.5 and 4.5. However, dysbiosis of vaginal microbiome increases the pH level, leading to the incidence of vaginitis. The commensal vaginal bacterium Dermabacter vaginalis-which was isolated from the vaginal fluid of a Korean female-was incubated in acidic and neutral pH to simulate healthy and vaginitis conditions, respectively. The chemical profiles of the two different cultures were compared using HPLC. The compound showing distinctive difference between the two sets of data was presumed to be a chemical messenger, which was identified as cyclo(L-pro-L-met) by analysis of NMR, MS, and specific rotation data. Synthesis was achieved in three steps (overall yield 15%), enabling structure confirmation and antimicrobial evaluation against vaginal pathogens. Cyclo(L-pro-L-met) showed antifungal activity against Candida albicans, a major cause of vulvovaginal candidiasis.

Purpose: It has been reported that the diversity and abundance of microbes in the vagina decrease due to the use of antimicrobial agents, and the high recurrence rate of female vaginitis due to this suggests that a new treatment is needed. Methods: In the experiment, we detected that 10% potassium sorbate solution, 1% eucalyptus oil solution, 1% tea tree oil solution, 400 µL/10 mL grapefruit seed extract solution, 100% lactic acid, 10% acetic acid solution, and 10% lactic acid solution were prepared and used. After adjusting the pH to 4, 5, and 6 with lactic acid and acetic acid in the mixed culture medium, each bacterium was inoculated into the medium and incubated for 72 h at 35℃. Incubate and 0 h each. 24 h. 48 h. The number of bacteria was measured after 72 h. Results: In the mixed culture test between lactic acid bacteria and pathogenic microorganisms, lactic acid bacteria showed good results at pH 5-5.5. Potassium sorbate, which has varying antibacterial activity based on the pH, killed pathogenic bacteria and allowed lactic acid bacteria to survive at pH 5.5. Conclusion: The formulation ratio obtained through this study could be used for the development of a feminine cleanser that can be used as a substitute for antibacterial agents. Further, the findings of this study may be able to solve the problem of antimicrobial resistance in the future.

This study was performed to evaluate anti-thrombotic activities and anti-inflammatory effects of ChungyeolHaedogHwaeoTang water extract(CHHT). The results were summarized as follows. In experiment of anti-thrombotic effect; 1. CHHT inhibited human platelet aggregation induced by ADP and epinephrine as compared with the control group, and inhibited pulmonary embolism induced by collagen and epinephrine (inhibitory rate is 37.5%). 2. CHHT increased platelet number significantly, and also CHHT shortened PT and APTT significantly as compared with the control group in thrombus model induced by dextran. In experiment of anti-inflammatory effect; 3. CHHT inhibited $IL-1{\beta}$, IL-6, TNF-${\alpha}$, COX-2 and NOS-II mRNA expression as compared with the control group in a concentration-dependent degree, and inhibited NO production significantly at 50, 100 ${\mu}g/ml$, and also inhibited ROS production in a concentration-dependent degree as compared with the control of group in RAW 264.7 cell line. 4. CHHT inhibited $IL-1{\beta}$, IL-6 and TNF-${\alpha}$ production significantly in serum of acute inflammation-induced mice, and decreased $IL-1{\beta}$, IL-6 and TNF-${\alpha}$ production in spleen tissue, and also decreased $IL-1{\beta}$, and IL-6 production in liver tissue, but increased TNF-${\alpha}$ production in liver tissue of acute inflammation-induced Balb/c mice. 5. CHHT increased survival rate from the 3rd day in ICR mice with lethal endotoxemia induced by LPS. These results suggest that CHHT can be useful in treating diverse female diseases caused by thrombosis and inflammation such as menstrual pain, menstrual disorder, leukorrhea, vaginitis, cervicitis, pelvic inflammatory disease and so on.

Purpose: This study was carried out to evaluate the efficacy of intravaginal pelvic floor electrical stimulation (FES) therapy on bladder irritability symptoms in stress urinary incontinent women. Materials and Methods: The evaluation before and after treatment included the Blaivas's female Bladder Questionnaire, the quality of life questionnaires and the overall satisfaction with present voiding state using visual analogue test (VAT). All patient were treated for 20 minutes, twice a week for 6 weeks, using a new intravaginal electrical stimulator with microchip (PIC16C74). Results: After the FES therapy, the overall success rate of the SUI was 50.4.% at 9 months. The bladder irritability symptoms such as frequency, nocturia, urgency, residual urine sensation and lower abdominal discomfort were improved. In particular, the symptoms of frequency, urge incontinence, dysuria were significantly improved after the FES therapy at 9 months. The VAT score of the overall satisfaction with the present voiding state was significantly lower after the FES therapy. 73.7% of patients were satisfied with the FES therapy and complications such as hemorrhage, vaginitis, urinary tract infection and pain were not encountered. Conclusion: These results suggest that FES therapy with microchip improves some bladder irritability in SUI women. Therefore, electrical stimulation therapy should be considered as a first line therapy in SUI women with bladder irritability symptoms.

Many antibiotic monographs cite the induction of vaginal infections as a possible side effect. Invariably, this is believed to be due to Candide albicans, and empirical therapy is given. However, recent studies raise the question of the extent to which yeast do infect the host after antibiotic use. A double-blind, randomized, placebo-controlled study was undertaken on female patients to determine how many yeast infections occurred following 10 days antibiotic use. In addition, the study was designed to examine whether oval use of probiotic lactobacilli can reduce the risk of vaginal infection. Twenty four patients diagnosed with respiratory, oval or throat infections received one of several types of antibiotic for 10 days, and two capsules containing 10$^{9}$ dried Lactobacillus rhamnosus GR-1 and L. fermentum RC-14 from the day of commencement of antibiotic therapy for 21 days. The most commonly prescribed antibiotic was biaxin (clarithromycin). All but one patient had lactobacilli in the vagina upon entry to the study, and none developed yeast vaginitis or diarrhea during treatment or 20 days after completion of antibiotics. The mean Nugent score was higher in the placebo than the lactobacilli group (4.1 versus 2.4), and three cases of bacterial vaginosis arose (25 % incidence compared to 0% in the lactobacilli group) in the placebo group (2 receiving cefuroxime, 1 on biaxin). The study suggested that current antibiotic use is not necessarily associated with either diarrhea or yeast infection, as is often surmised. Nevertheless, daily use of probiotics was safe and could potentially reduce the risk of patients developing bacterial vaginosis after antibiotic use.

Chemical burn on the oral mucosa is caused by contact with various chemical products and manifests with localized mucositis, keratotic white lesions, bleeding, and painful tissue surface due to the coagulation of the tissue. Policresulen ($Albothyl^{(R)}$) is a topical antiseptic, commonly used over-the-counter drug for vaginitis, thrush and stomatitis. This drug is highly acidic with pH 0.6, and can act as a strong corrosive agent to oral mucosa. When inadvertently used in oral cavity, it may cause chemical burns of oral mucosa, resulting necrosis and bleeding surface resembling to erythema multifome. A 56 years old female patient presented with the chief complaints of painful ulcerations on the tongue, the upper and lower lips. On intraoral examination, an erythromatous, erosive or ulcerative surface covered with inflammatory exudates or bleeding crust is observed on the anterior half of the tongue and the upper and lower lips. She has occasionally applied the policresulen solution topically on the tongue to relieve pain from recurrent focal glossitis for about 10 years. In this time she applied it broadly and repeatedly to the tongue, the upper and lower lips for the purpose of pain relief by herself without instruction by physician or dentist. After cessation of policresulen application, the oral mucosa was rapidly recovered with use of topical steroids. In 2 weeks the lesions subsided completely. In summary, inadvertent use of $Albothyl^{(R)}$ on oral mucosa may result in chemical burn, causing mucosal erosion, ulceration and inflammation. It can be recovered by topical use of corticosteroid for 2 weeks after cessation of using $Albothyl^{(R)}$.

To investigate the inhibition effect on pathogenic microbes and the antimicrobial resistance of probiotics, a total of 140 probiotics were isolated from 35 kinds of Korean commercially available Kimchi. Of those, L. plantarum was identified from 53 strains (37.9%), E. faecium from 27 strains (19.3%), and L. rhamnosus from 7 strains (5.0%) using 16S rRNA gene sequencing. Sixty nine strains (49.3%) showed overall antimicrobial activity against pathogenic microbes, namely S. Typhi, S. Enteritidis, E. coli O157:H7, S. flexneri, NAG Vibrio, Listeria monocytogenesis, Y. enterocolitica, S. aureus, S. pyogenes, G. vaginalis, C. albicans, and P. acne. The proportions of L. plantarum, E. faecium, and L. rhamnosus strains to pathogenic microbes were 75.5%, 40.7%, and 28.6%, respectively. In addition, a resistance test with 18 antimicrobial agents using a disk diffusion assay revealed a resistance incidence of 98.6% for nalidixic acid, 83.6% for streptomycin, 75.7% for gentamicin 73.6% for vancomycin, 72.1% for norfloxacin, and 67.9% for ciprofloxacin. In conclusion, L. plantarum, L. sakei, and E. faecium strains with various antimicrobial activities and broad antibiotic resistance are useful for treating diarrhea in long-term inpatients and for the alternative use for treating Candida species female vaginitis.
