BACKGROUND ChondroT, a new herbal medication, consists of Angelica grosseserrata Maxim., Lonicera japonica Thunb., Angelica gigas Nakai, Clematis terniflora var. manshurica (Rupr.) Ohwi, and Phellodendron amurense Rupr. (6:4:4:4:3). Our previous studies have shown that ChondroT exhibits significant anti-arthritic and anti-inflammatory effects. In this study, we aimed to assess the toxicological safety assessment of ChondroT. METHODS This study was designed to assess the safety of ChondroT after repeated oral administration. Male and female Sprague-Dawley rats were treated with ChondroT at oral doses of 0, 500, 1000, and 2000 mg/kg for 13 weeks. Mortality, clinical signs, body weight changes, food consumption, ophthalmological findings, urinalysis, hematological and blood-chemical parameters, necropsy findings, organ weights, and histological markers were recorded throughout the study period. Rats were also monitored for an additional 4 weeks to determine the recovery time. RESULTS No death occurred and no significant changes in food consumption, ophthalmologic findings, and urinalysis were found. Although there were alterations in clinical signs, body weights, hematological parameters, blood-chemical parameters, necropsy findings, organ weights, and histological markers, they were not considered to be toxicologically significant. CONCLUSIONS The results suggest that the no-observed adverse effects level (NOAEL) was 2000 mg/kg/day for the test substance. ChondroT, a new complex herbal medication composed of five plants, can therefore be used safely at the NOAEL.

对Sprague-Dawley大鼠中的ChondroT进行13周重复口服剂量毒性研究。

背景技术ChondroT是一种新的草药,由当归,当归忍冬,当归,海地铁线莲组成。曼苏里卡(Rupr。)Ohwi和Phellodendron amurense Rupr。(6:4:4:4:3)。我们以前的研究表明,ChondroT具有明显的抗关节炎和抗炎作用。在这项研究中,我们旨在评估ChondroT的毒理学安全性评估。方法本研究旨在评估反复口服后ChondroT的安全性。将雄性和雌性Sprague-Dawley大鼠分别以口服剂量0、500、1000和2000 mg / kg的ChondroT处理13周。死亡率,临床体征,体重变化,食物消耗,眼科检查结果,尿液分析,血液和血液化学参数,尸检结果,器官重量,在整个研究期间记录组织学标志物。还监视大鼠另外4周以确定恢复时间。结果未发生死亡,食物消耗,眼科检查结果和尿液分析未见明显变化。尽管临床体征,体重,血液学参数,血液化学参数,尸检结果,器官重量和组织学标志物有所改变,但它们在毒理学上并不重要。结论结果表明,受测物质的未观察到的不良反应水平(NOAEL)为2000 mg / kg / day。ChondroT是一种由五种植物组成的新型复杂草药,因此可以在NOAEL上安全使用。还监视大鼠另外4周以确定恢复时间。结果未发生死亡,食物消耗,眼科检查结果和尿液分析未见明显变化。尽管临床体征,体重,血液学参数,血液化学参数,尸检结果,器官重量和组织学标志物有所改变,但它们在毒理学上并不重要。结论结果表明,受测物质的未观察到的不良反应水平(NOAEL)为2000 mg / kg / day。ChondroT是一种由五种植物组成的新型复杂草药,因此可以在NOAEL上安全使用。还监视大鼠另外4周以确定恢复时间。结果未发生死亡,食物消耗,眼科检查结果和尿液分析未见明显变化。尽管临床体征,体重,血液学参数,血液化学参数,尸检结果,器官重量和组织学标志物有所改变,但它们在毒理学上并不重要。结论结果表明,受测物质的未观察到的不良反应水平(NOAEL)为2000 mg / kg / day。ChondroT是一种由五种植物组成的新型复杂草药,因此可以在NOAEL上安全使用。尽管临床体征,体重,血液学参数,血液化学参数,尸检结果,器官重量和组织学标志物有所改变,但它们在毒理学上并不重要。结论结果表明,受测物质的未观察到的不良反应水平(NOAEL)为2000 mg / kg / day。ChondroT是一种由五种植物组成的新型复杂草药,因此可以在NOAEL上安全使用。尽管临床体征,体重,血液学参数,血液化学参数,尸检结果,器官重量和组织学标志物有所改变,但它们在毒理学上并不重要。结论结果表明,受测物质的未观察到的不良反应水平(NOAEL)为2000 mg / kg / day。ChondroT是一种由五种植物组成的新型复杂草药,因此可以在NOAEL上安全使用。
