Thirteen-Week Study of PM014 Subchronic Oral Toxicity in Rats
PM014 is a modified herbal formula based on Chung-Sang-Bo-Ha-Tang, which is a well-known prescription drug used for curing various inflammatory pulmonary diseases. We previously showed that PM014 attenuated lung inflammation in a murine model of chronic obstructive pulmonary disease (COPD). The objective of the present study was to evaluate the chronic oral toxicity of PM014 in rats. PM014 was ...
متن کاملThirteen-week oral toxicity study of 1,4-dichloro-2-nitrobenzene in rats and mice.
Subchronic toxicity of 1,4-dichloro-2-nitrobenzene (DCNB) was examined by feeding F344 rats and BDF mice of both sexes a diet containing 1,481, 2,222, 3,333, 5,000 or 7,500 ppm DCNB (w/w) for 13 wk. Oral administration of DCNB in feed to rats and mice retarded growth rates and induced subchronic toxicity affecting the liver, kidney, testes and blood. Liver and kidney were most responsive to DCN...
متن کاملThirteen-week inhalation toxicity of 2- and 4-chloronitrobenzene in F344/N rats and B6C3F1 mice.
Toxicity studies were performed by exposing F344/N rats and B6C3F1 mice to 2- and 4-chloronitrobenzene (CNB) by whole-body inhalation 6 hr/day, 5 days/week, for 13 weeks. Animals were evaluated for clinical chemistry (rats), hematology (rats), histopathology, and body/organ weights. Exposure concentrations were 0, 1.1, 2.3, 4.5, 9, and 18 ppm for 2-CNB and 0, 1.5, 3, 6, 12, and 24 ppm for 4-CNB...
متن کاملThirteen-week inhalation toxicity of carbon tetrachloride in rats and mice.
Subchronic toxicity of carbon tetrachloride (CCl4) was examined by inhalation exposure of F344 rats and BDF1 mice of both sexes to 0, 10, 30, 90, 270 or 810 ppm (v/v) CCl4 vapor for 13 wk (6 h/d and 5 d/wk). In the high exposure levels at 270 and 810 ppm, altered cell foci in the livers of both rats and mice, and fibrosis and cirrhosis in the rat liver were observed. Hematoxylin and eosin-stain...
متن کاملThirteen-Week Oral Dose Toxicity Study of G. bimaculatus in Sprague-Dawley Rats
Gryllus bimaculatus (Gb) was orally administered at doses of 0, 0.04, 0.2, 1 and 5 g/kg bw/day for 13 consecutive weeks. There were no observed clinical signs or deaths related to treatment in all the groups tested. Therefore, the approximate lethal oral dose of G. bimaculatus was considered to be higher than 5 g/kg in rats. Throughout the administration period, no significant changes in diet c...
