2.3 Stability experiment Take the nitric acid, pistachio, musk, sea bream / 1 skill, the next experiment.
2.3.1 Effect of release time on optical rotation: Separation, 51, determination of sub-rotation, the results show that in 4 11 rotation does not change.
2.3.2 The effect of temperature on the optical rotation; the optical rotation was measured at different temperatures, and the results showed that it was in the range of 151:~351. The optical rotation is not affected by the temperature. 2.4 Recycling test The precision of the nitric acid and the auxiliary ingredients are accurately weighed according to the prescription. Add water to dissolve into a 1 8 / 1 concentration solution. According to the Chinese Pharmacopoeia 95 edition two appendix 35 page method to determine its optical rotation, calculation. result.
Qiaohao 2.5 This method compares with the neutralization method to take different batches of nitric acid and fragrant scented scented scented scented scented scented liquid, according to the law, and compared with the neutralization method. result.
The batch number is rotated and neutralized. The experiment demonstrates that the optical rotation method is used to determine the tooth content of the scented scented scented scent of the scented scented scented scent, which is compared with the neutralization method of the Chinese hospital preparation specification. The results are relatively close, but because the method has the advantages of simple and rapid operation, and the sample can be directly measured without any treatment, the optical rotation method can be used for the quality control and rapid analysis of the hospital preparation room, the pharmaceutical factory.
Comparison of the effects of different methods of cleaning infusion bottles on insoluble particles of infusions Zhang Xueling's intimate particles are important indicators of infusion quality. With the improvement of infusion production conditions and the continuous improvement of solvent and solute quality, infusion bottles have become the main way to inject human particles. At present, _. high-efficiency and non-toxic containing disinfectant cleaning agent has gradually replaced the thick sulphur cleaning liquid, widely used in the cleaning of infusion bottles. To this end, this article compares the two disinfectant lotions commonly used with the effect of traditional cleansing and infusion liquefaction.
1 material series and method to prepare 300 old infusion bottles, and prepare the following drugs; 1 concentrated sulfuric acid cleaning solution; 2 Jiexiaojing Suzhou Wuxian Chemical Second Factory. Batch No. 9608193 Strong disinfection of Guangzhou Qingfeng Pharmaceutical Machinery Factory, batch number 950906. Prepare 11.4 type particle counting device Hunan Tianping Instrument Factory. Take the old and liquefied liquefied open-air stack for 8 months. The 00 bottles of the recovered liquids are removed. After removing the caps, rinse them with normal water. The mixture is divided into 3 groups, each group of 100, each with concentrated sulfuric acid cleansing solution. 5 words to eliminate sperm and 5 strong disinfection and wash. Leave overnight and rinse twice with normal water. The filtered water for injection was washed twice, and the same batch of glucose-scented sodium injection was placed, sealed, and placed for 2 weeks after sterilization. According to the Chinese Pharmacopoeia 1995 edition appendix 62 page and appendix 79 pages, appendix 76 pages, respectively, insoluble granules and sterility, endotoxin test.
2 Results 2.1 no seedling inspection 3 kinds of infusion bottle cleaning method produced grape Qiao chlorinated injection. According to the direct inoculation method, the nurturing bacteria and anaerobic culture medium were cultured for 5 days at 301 to 35 r, and the mold culture medium was cultured at 20 r - 25 r for 7 days. Sterile growth. Bacterial dedication test: Glucose debride injection produced by three infusion bottle cleaning methods, according to the bacterial endotoxin test. The results meet the requirements of 2.2 non-falling granules - 1 kind of skillful method infusion finished product granules skillfully 1 = 100 groups of sour acid Qiao Jie Xiaoqiao strong 辜 辜 net note; comparison between groups is greater than 0.05 3 Discussion chair results show that 3 The treatment method showed no significant difference in the infusion of the finished microparticles, and the sterility and endotoxin tests were in compliance with the regulations. Compared with the cleansing liquid of sulfuric acid, it has the same decontamination and depyrogenation effect.
Huaqiao Unit: Qiqihar Medical College Qiao Er Affiliated Hospital Fujian Yu, Zhang Xueling Qiqihar City Medical Qiao Building Qiao Yang Mail Qiaohua 1006 to receive the date 20000 Because most of the disinfectant lotion contains builders and other materials, wash the infusion bottle After the skillful setting, these are easy to adhere to the bottle wall and are not easy to wash. Therefore, the water pressure during flushing should be larger on the 58.8kPaU or the water is cooled by the warm water.
The old infusion bottle used in the experiment, in which 30 appearance is seriously polluted, such as mildew in the chemical. There are blood, sediment and debris. It is stored for less than 3 months than the conventional hospital infusion production, and it is more difficult to clean about 1 to 5 with serious appearance pollution. Because this experiment was carried out in the normal infusion production process of this hospital, the parallel operation, the experimental data is more practical.
