Acute Toxicity Test of Chinese Herbal Compound Tongmai Tangyanming Capsule

[Objective] This study was conducted to determine the safe dose of Tongmai Tangyanming capsule in clinic by evaluating its acute toxicity, so as to ensure clinical medication safety. [Method] The test was designed according to ＂Technique Requirements of Research of New Chinese Medicine＂ and ＂Guide for Research of New Chinese Medicine＂, mice were intragastrically administrated with Tongmai Tangyanming capsule at a maximum concentration and a maximum volume, and the acute toxic response of mice was observed, so as to determine medi- na lethal dose （LDso） and maximum administration dosage of Tongmai Tangyanming capsule. [Result] The LD^o could not be detected in the test, and the maximum administration dosage of mouse was calculated to be 112.104 g of dried herbs/（kg.d）, equivalent to 260 times of clinical dose of adult. [Conclusion] Chinese herbal compound Tongmai Tangyanming capsule has low acute toxicity, and its clinical dose is safe and reliable.

Acute Toxicity Test of Qiangli Bupi Paste

[Objective] The toxicity of Qiangli Bupi Paste was investigated, to provide a test basis for its further development and safe use. [Method] Forty Kunming mice, half male and half female, were selected and divided into the CK group and the Qiangli Bupi Paste group, each of which included 20 mice. The acute toxicity of Qiangli Bupi Paste was observed by the maximum administration dosage method. No mice and abnormal response were observed within 14 d in various groups. The tested animals were also subjected to anatomical observation. [Result] All the tested animals survived in the test, and behaved normally, with glossy hair. Their body weights accorded with the growth regularity. During the anatomy, no important vis- ceral organs showed pathological changes, and there were no significant differences in body weight between the two groups before administration, on the 7~ after ad- ministration and the 14 d after administration （P〉0.05）. [Conclusion] In the acute toxicity test of Qiangli Bupi Paste, the maximum administration dosage was 48 g/kg （equivalent to 96 times of the daily dose of adult in clinic）, and no obvious toxic response was observed.

Experimental study on acute toxicity of Lucao Wenban granules

Background:To evaluate the acute toxicity of the experienced prescription Lucao Wenban granules on mice and provide a theoretical basis for clinical medication safety.Methods:The mice were not deprived of water for 16 h after fasting,and were intragastrically given the experienced prescription Lucao Wenban granules at the maximum mass concentration(0.55 g/mL)and the maximum volume(0.04 mL/g body weight)2 times within 24 hours.The toxicity was observed and recorded within 14 days after administration.At the end of the experiment,the biochemical indexes of mice were detected.The liver,heart,spleen,lung,and kidney were dissected and observed after executing mice to weigh the wet weight and calculate the coefficient of viscera.Results:There was no death after the mice were given 342.32 g/kg of crude medicine of the experienced prescription Lucao Wenban granules.No significant differences were detected in body weight,biochemical indexes,visceral index between the experiment group and the control group.Conclusion:There is no acute toxicity in mice.The maximum tolerable dose is 342.32 g/kg,which is 144 times of clinical dose.
