RESUMEN

Objective To observe the acute toxicity of local achyranthes aspera, and its injury to major internal organs. Methods Estimated the dose before the experiment, then selected 40 mice and divided them into five groups randomly, namely 4 dose-groups and one control group. The doses used in the dose-groups were 400 g/kg, 300 g/kg, 225 g/kg and 169 g/kg respectively. Observed the symptoms and the death for successive 7 days and calculated LD (50)with statistic methods. Dissected the dead mice and observed the lesion of organs. Results The LD50 of acute toxicity test of achyranthes aspera was 309.21 g/kg, Sx=0.0359 g/kg. 95% of the limit of trust was 309.14~309.28 g/kg. According to the acute toxic standard, it belonged to non-toxicity. The specimen revealed that large dose administration caused coagulation of blood in both liver and spleen. Conclusion Local achyranthes aspera had little toxicity. Large dose administration affected heart function of mice.

RESUMEN

OBJECTIVE:To establish a method for simultaneous determination of the contents of three components in synthesis and actual satongfeng injection.METHODS:A flexible tolerance simplex method was used for multi-wavelength spectrophotometry with interval of 1nm in 258~290nm wavelenth,33 wavelenths were selected.RESULTS:The linear range and average recoveries rate of sodium salicylate,phenazone and caffeine were 0~42,0~12,0~6?g?mL-1 and(99.93?0.22)%,(99.85?0.24)% and(100.19?0.40)% respectively.All were agreed with those by standard method.CONCLUSIONS:This method is easy in operation,fast and reproducible,applicable to automatic analysis,and therefore can be used for the quality control of the preparation.
