Objective:To generate monoclonal antibodies against ciprofloxacin (CIP) and to analyze its immunological traits for establishing a determination method for ciprofloxacin residues in food tissues.Methods:BALB/c mice were immunized by the conjugation of CIP-BSA successfully.The splenic cells of BALB/c mice and the oncocyte were fused and screened in HAT culture medium.Cell strains of 1C9,3F6,6H2,6A7,6G11 and 8F5 were cloned,which could secret the monoclonal antibody (Mab) for ciprofloxacin.Results:By ELISA method,the haplotype of Mabs were identified.The antibody secreted by 1C9,3F6 and 6A7 were classified to the IgG2a.Those of 6H2 and 8F5 were classified to the IgG1 while 6G11 to IgG3.The results of SDS-PAGE showed that the Mab protein was made up of the weight chain and the light chain whose molecular weight were 50 kD and 25 kD,respectively.All of those Mabs had fine specificity and sensibility.The indirect ELISA titer of 1C9 was 1:6.4?102 in supernatant and 1:5.6?105 in ascites.The affinity of 1C9 was 2.85?109 L/mol and the value of IC50 reached to 245.86 ng/ml.The protein secreted by 1C9 was screened for establishing the ELISA method and the detective limitation reached to 45.25 ng/ml.There were no cross reactions to Ofloxacin,Difloxacin,Sarafloxacin,Malachite green,Chloramphenicol and Furacilin while the rate of cross reaction to Enrofloxacin could reach to 84.6%.Conclusion:The Mabs are sensitive and specific,which are suitable to be applied in establishing immunoassay of CIP residues.

OBJECTIVE: To figure out the etiological factors and overall mortality of the patients with acute intestinal obstruction, and to explore the rational period of conservative therapy before operation. METHODS: Medical records of all the patients with acute intestinal obstruction admitted to West China Hospital from 1995 to 2002 were retrospectively reviewed. The etiology of the obstruction was categorized, and the correlation of mortality and time interval between conservative therapy and operation was analyzed. RESULTS: There were 705 patients with acute intestinal obstruction included. There were 71.1% of the obstruction lesions located on the small bowel, and 82.6% of the patients experienced simple obstruction. The most frequent cause was adhesions (62.0%), and next was neoplasms (23.7%). There were 57.6% of the patients underwent the surgical treatment. The overall mortality rate was 1.6%, and the mortality rates in conservative therapy and surgical intervention groups were 1.3% and 1.7% respectively. The intestinal necrosis rate was increased gradually with the prolongation of time interval between conservative therapy and operation, and the death might occur 24 hours after strangulation. CONCLUSION: The epidemiological transition to adhesive obstruction still exists in China, and it is similar to that in Western countries. In our experience, near half of the patients with simple obstruction may achieve palliation by conservative therapy. Surgical intervention is indicated for the patients with prolonged and non-palliated simple obstruction, or strangulation disease within the first 24 hours.
