Abstract:
This study aimed at exploring the application of microtox technology to the evaluation of comprehensive toxicity of Sheng Mai injections.Characteristic parameters of vibrio fischeri (CS234) were measured by methodology inspection under different conditions to optimize the reaction condition with reliable technology.It was the first experiment to accomplish the comprehensive toxicity of Sheng Mai injections from various manufacturers using vibrio fischeri under the target condition.It was found that parameters of the optimum condition contained 0.9 mL recovery liquid volume in each freeze-dried vial and 50 μ L bacteria suspension of each sample,being included in 2 mL solution in aggregate under 10 mins' detection time after adding bacteria suspension with the favorable pH value ranging from 5 to 10 and luminous intensity from 0.8 to 1.2 million within 10 mins.The relative standard deviation values of replication experiment and precision test were all below 15％.Under this optimum detection condition,it was found that the EC50 values were 22.10％,34.10％ and 46.04％,respectively,presenting significant statistical differences (P＜0.05).These results demonstrated that the growth of biological detection standards of Sheng Mai injection was highlighted a long way to go.Besides,the microtox-based fast test for the evaluation of the comprehensive toxicity of Sheng Mai injection showed a prospective application to controlling the quality of different products from manufacturers.
