Abstract:
BACKGROUND: Metronidazole has been known as the most effective drug for treatment of Trichomonas vaginalis-related diseases. However, it has been reported that metronidazole has adverse effects and incidence of metronidazole-resistant T. vaginalis (CDC085) has increased. Development of new drug, which is effective against metronidazole-resistant T. vaginalis and showing no adverse effects, has been required. METHODS: The purpose of this study was to investigate effects of various extracts from herbs such as Quisqualis indica, Gleditsia sinensis, Prunus armeniaca, Morus alba, Platycodon grandiflorum, Ailanthus altissima, Stemona japonica, Biota orientalis, Dryobalanops aromatica, and Cimicifuga heracleifolia on metronidazole resistant strain of T. vaginalis in vitro (CDC085). RESULTS: Anti-Trichomonas activities were observed in T. vaginalis treated with G. sinensis, P. armeniaca, and P. grandiflorum on the growth and fine structure of metronidazole resistant strain of T. vaginalis. Of the three standard extracts that showed the most effective anti-trichomonas activity, G. sinensis was the most effective. The inhibitory effects of fraction extracts of this drug were shown on the growth of T. vaginalis. The fine structure of the cytoplasm was changed after application of G. sinensis extract. The number of polyribosome and hydrogenosome decreased whereas the number of food vacuole and vacuole in the cytoplasm increased, compared with that of untreated control group. CONCLUSION: The results of our study indicate that G. sinensis may induce the inhibition of cell multiplication as well as impairment of protein synthesis of metronidazole resistant strain of T. vaginalis in vitro.
