A Thirteen Week Repeated Oral Dose Toxicity Test and A Four Week Recovery Test of ACM(Added Chongmyung-tang) in Sprague-Dawley Rats

Objectives: To provide information on the safety of ACM, we carried out a 13-week repeated oral dose toxicity and a 4-week recovery test of ACM in Sprague-Dawley rats. Methods: Female and male rats were treated with ACM with oral doses of 800, 2000, and 5000 ㎎/㎏. The ACM was administered for 13 weeks. Mortality, clinical signs, body weight changes, food consumption, ophthalmologic findings, urinalysis, hematological and biochemical parameters, gross findings, organ weights and histological markers were monitored during the study period. Moreover, the rats were monitored for 4 extra weeks to determine recovery time after the study period. Results: We found no mortality and no abnormalities in clinical signs, body weight, food consumption, ophthalmologic findings, urinalysis, hematological and biochemical parameters, gross findings, organ weights and histological markers in any of the rats tested
