Developing specific drug/device combination products improves the treatment level of the acute chemical injury / 国际药学研究杂志

To deal with effectively acute chemical injury events, the service ability of protective medicine against chemical weapons has being widened from dealing with traditional chemical warfare to public chemical accident or chemical terrorist attack. Focusing on the important researching and developing of medicine for chemical defense use only, the novel drug/device combination products should be vigorously promoted including the new mechanism, good curative effect and high safety of detoxification drugs such as hydroxycobalamin used in the treatment of known or suspected cyanide poisoning in both adults and the pediatric population, and the convenient and quick drug delivering technologies such as auto-injectors with a retreat hidden needle and a smart remindful injection, which could improve greatly the emergency medical rescue ability of chemical accidents.

Study on Photolysis of Vitamin B_(12) and New Method to Determine the Contents of Vitamin B_(12) in Fermentation Broth / 中国生物工程杂志

The photolytic behavior of deoxyadenosylcobalamin and methylcobalamin in water solution was investigated with high performance liquid chromatography. The results indicated that the photolytic cleavage rate increased with the light intensity, according to which a new method was developed to determine the concentration of vitamin B12 in fermentation broth. The samples were completely photolyzed after cell disruption. The content of vitamin B12 was obtained by determining the content of the hydroxycobalamin. The method shows many advantages, such as rapidness, high accuracy and low sample quantity needed, over traditions methods. The developed method may be used in the field of vitamin B12 fermentation.
