Non-clinical safety evaluation of Yongdamsagan-tang water extract: A 13-week subchronic oral toxicity study in Sprague Dawley rats.
Despite the continued clinical application of traditional herbal medicines, scientific evidence such as toxicological safety profile of Yongdamsagan-tang water extract (YSTW) has not yet been established. The purpose of this study was to investigate the potential toxicity profile of YSTW following a 13-week repeated oral administration at various concentrations to Sprague Dawley rats. YSTW was administered orally to rats once daily at doses of 0, 1000, 2000, and 5000 mg/kg bw/day for 13 weeks. During the experimental period, there were no significant toxicological changes related to YSTW treatment. These results indicate that the administration of YSTW for 13 weeks in the rat resulted in no signs of toxicity at up to 5000 mg/kg bw/day, which was considered the no-observed-adverse-effect level.
期刊介绍：
Journal of Applied Toxicology publishes peer-reviewed original reviews and hypothesis-driven research articles on mechanistic, fundamental and applied research relating to the toxicity of drugs and chemicals at the molecular, cellular, tissue, target organ and whole body level in vivo (by all relevant routes of exposure) and in vitro / ex vivo. All aspects of toxicology are covered (including but not limited to nanotoxicology, genomics and proteomics, teratogenesis, carcinogenesis, mutagenesis, reproductive and endocrine toxicology, toxicopathology, target organ toxicity, systems toxicity (eg immunotoxicity), neurobehavioral toxicology, mechanistic studies, biochemical and molecular toxicology, novel biomarkers, pharmacokinetics/PBPK, risk assessment and environmental health studies) and emphasis is given to papers of clear application to human health, and/or advance mechanistic understanding and/or provide significant contributions and impact to their field.
