Abstract

To assess the safety of oral compound honeysuckle moisturizing Chinese herbal extract for eczema treatment, Sprague-Dawley (SD) rats were oral administered three doses (20.8, 41.6, and 83.3 g/kg, based on raw materials) of the extract daily for 13 consecutive weeks. The study aimed to identify potential toxic reactions, mortality due to accumulation, and recovery after discontinuation. By observing these factors, we sought to determine the target organs of toxicity and establish nontoxic doses for SD rats. The results indicated that during the administration period and subsequent recovery period, there were no significant abnormalities in weight gain, food intake, hematology, blood biochemistry, or urine indicators. Additionally, histopathological analysis of major organs (heart, liver, lungs, kidneys, spleen, and brain) revealed no significant extract-related lesions. Moreover, no significant local toxic lesions were observed in the oral buccal and tongue mucosa. Finally, under the experimental conditions of this study, the preliminary nontoxic response dose of oral gavage compound honeysuckle moisturizing Chinese herbal extract administered to SD rats for 13 weeks was 83.3 g/kg/day (calculated as raw medicine).

复方金银花保湿中药提取物灌胃13周对大鼠的毒性研究。
为评价复方金银花保湿中药提取物口服治疗湿疹的安全性,采用SD大鼠连续13周,每天口服三剂量(20.8、41.6和83.3 g/kg,根据原料不同)金银花保湿中药提取物。该研究的目的是确定潜在的毒性反应,由于积累的死亡率和停药后的恢复。通过观察这些因素,我们试图确定SD大鼠的靶器官毒性并建立无毒剂量。结果显示,在给药期间和随后的恢复期,体重增加、食物摄入、血液学、血液生化、尿液指标均无明显异常。此外,主要器官(心、肝、肺、肾、脾和脑)的组织病理学分析显示没有明显的提取物相关病变。口腔颊、舌黏膜未见明显局部毒性病变。最后,在本研究实验条件下,SD大鼠灌胃复方金银花保湿中草药提取物13周的初步无毒反应剂量为83.3 g/kg/天(以生药计算)。

期刊介绍: Drug and Chemical Toxicology publishes full-length research papers, review articles and short communications that encompass a broad spectrum of toxicological data surrounding risk assessment and harmful exposure. Manuscripts are considered according to their relevance to the journal. Topics include both descriptive and mechanics research that illustrates the risk assessment implications of exposure to toxic agents. Examples of suitable topics include toxicological studies, which are structural examinations on the effects of dose, metabolism, and statistical or mechanism-based approaches to risk assessment. New findings and methods, along with safety evaluations, are also acceptable. Special issues may be reserved to publish symposium summaries, reviews in toxicology, and overviews of the practical interpretation and application of toxicological data.
