报告了榆林大骨节病新发户水黄腐酸（ＦＡ）对大鼠急性毒性实验结果。以４００ｍｇ·ＦＡ／ｋｇＢＷ一天灌胃于组Ⅲ的４只鼠观察７天，以３００ｍｇ·ＦＡ／ｋｇＢＷ·ｄ灌胃于组Ⅱ的５只鼠，其中１只连续３天，１只４天，１只６天，余２只连续７天。全部动物于实验第８天取材处死。实验结果：未见两组大鼠ＦＡ致死的鼠。未见两组大鼠主要生命器官和骨软骨病理形态变化。组Ⅲ鼠摄ＦＡ量是病区儿童每公斤体重等效剂量的６８００倍，组Ⅱ鼠７天摄入量达２１００ｍｇ／ｋｇＢＷ，是病区儿童９８年的量。实验证明如此大剂量病区ＦＡ经消化道接触大鼠并未导致后者有可察觉的毒性损害表现
Reported Yulin Fahrenheit new home water fulvic acid (FA) in rats acute toxicity experimental results. Four rats in group Ⅲ were gavaged with 400 mg · FA / kg BW once a day for 7 days, and 5 rats in group Ⅱ were orally gavaged with 300 mg · FA / kg BW · d for 1 day, 1 for 4 days, 1 only 6 days, the remaining 2 only for 7 days. All animals were sacrificed on the 8th day of the experiment. Experimental results: no fatal rats were found in both groups. No major pathological changes of the vital organs and osteochondral in the two groups were observed. Group Ⅲ photo taken FA dose is equivalent to 6800 times the body weight of children per kilogram of body weight, group Ⅱ 7-day intake of 2100mg / kgBW, is the amount of children in the ward 98 years. Experiments show that such large doses of ward fa gastrointestinal exposure to rats did not lead to the latter has a perceived toxicity damage performance
