Objective To investigate the pathogen distribution and drug sensitivity in childhood bacillary dysentery,and to guide clinically the selection of reasonable antibiotics.Methods Bacterial drug susceptibility test was performed by standard Kirby-Bauer method.The results were interpreted according to NCCLS 2002.Results Of the 98 cases,there were two types of positive bacterial species:sh.flexneri(n = 77)and sh.sonnei(n = 21).Both sh.flexneri and sh.sonnei were sensitive to cefoperazone,eeftazidime,ceftriaxone,cefoperazone/sulbactam and fura- zolidone,and insensitive to ampicillin and co-trimoxazole.Conclusion sh.flexneri was the major pathogen of child- hood bacillary dysentery.The third generation cephalosporins were the first choice for shigella infections.

OBJECTIVE:To prepare Lornoxicam for injection and to study its stability.METHODS:The formular and pre paration technology of Lornoxicam for injection was optimized with the index of contents,the related substances and pH value;3batches of samples'stability was investigated.RESULTS:The best formula was found to be the following:4.0g of lornoxicam,4.0g of propylene glycol,100g of mannitol and sufficient quantum of1mol/L caustic soda,3batches of sample preparations man ufactured under this formula were found to be stable in quality in the accelerated,room temperature storage test under the condition of commercial packing.CONCLUSION:The formula design was reasonable and the preparation technology was feasible.
