Objective To evaluate the diagnostic value of tuberculosis antibody. Methods 564 patients re-ceived detection of serum,in which,508 cases suffered from active tuberculosis(TB) and 56 cases suffered from non-active TB. Results 508 cases with active TB received detection AB-Ab in serum, 48 cases were bacteriological smear positive cases, the rate of serum TB-Ab positive cases was 70.8% (34/48), the rate of pleural effusion or ascites TB-Ab positive cases was 44.4% (16/36), the rate of serum TB-Ab positive cases in another 424 cases with bacteriologi-cal smear negative TB was 39.6% (168/424). There was significant difference between active TB group and non-ac-tive TB group(χ2= 22.65, P<0.01). Conclusion It is useful for diagnosis of active TB by detecting TB-Ab. It may be a rapid auxilliary diagnostic way in TB diagnosis.

The application of surfactants in micelle electrokinetic chromatography is reviewed with 56 references, including the characteristic and application scope of the different types of surfactants and mixed surfactant micelle systems. The optimization strategy on the concentration of surfactants in separation is also discussed.
