Objective In order to increase the supervision of asarone injection and ensure the safety of clinical use, the samples of asarone injection in circulation in the market were tested. Methods In this paper, according to the national drug standards approved by the State Food and Drug Administration, the quality of 26 batches of asarone injection sampled by the institute was investigated, and the project evaluation of the variety traits, identification, pH value, color, related substances, loading, visible foreign bodies and content determination was completed. Results 26 batches of asarone injection were tested according to the standard, and all items were in conformity with the regulations. Conclusion The overall quality of this variety is good, but the properties of light degradation are observed. It is suggested to further optimize the production and use conditions, reduce the exposure time and avoid the formation of impurities.

Objective Discussion on the dilution of sulfur dioxide blank solution for determination of high-concentration sulfur dioxide samples. Methods Several experiments are done to Sulfur dioxide standard solution as sample. For the high concentration of sulfur dioxide exceeds the upper limit of the standard curve of absorbance (referred to as the out of sample, the same below), diluted with sulfur dioxide reagent blank solution (referred to as the blank solution, the same below) and then determination. Results The experimental results show that the absorbance of the sample, preferably not more than the upper limit of the standard curve is 0.100. Conclusion The dilution ratio should not be greater than 2 times; shake well placed 4-5 minutes after the determination as well; sulfur dioxide dilution and measured were lower than sulfur dioxide due to overloading, the samples should be more than the maximum absorbance value according to appropriately increase the sample number measured 4%-8%, make the results more close to the actual value.

Pseudomonas aeruginosa is a conditional pathogenic bacterium that can colonize the upper respiratory tract of pigs. If infected pigs do not have strong immunity or are in a stress state, it is likely to develop Pseudomonas aeruginosa, leading to diseases such as arthritis and meningitis in pigs, seriously damaging the economic benefits of pig farmers. This is very detrimental to the healthy development of China's pig industry. Considering the importance of early diagnosis for the prevention and control of Pseudomonas aeruginosa, this article analyzes Pseudomonas aeruginosa and focuses on the laboratory detection methods of Pseudomonas aeruginosa, in order to lay a foundation for the comprehensive prevention and control of Pseudomonas aeruginosa.
