ABSTRACT
【Objective】To investigate the role of mycophenolate mofetil (MMF) in the prevention of acute rejection in renal transplantation.【Methods】A total of 106 patients were randomized into two groups.One group received MMF (n=56),the other received azathioprine (Aza) (n=50).The time of the following study was within the first 6 months after transplantation.【Results】The rate of acute rejection of group receiving MMF was 20%,it′s lower than that of the group receiving Aza 44% (P<0.01).The recovery rate of acute rejection treated by methylprednisolone (MP),in MMF group 82% was higher than Aza group 55%.(P<0.05).Meanwhile the hepatotoxicity as well as cytomegalovirus (CMV) infection were lower in MMF group than those in Aza group.【Conclusion】MMF as a new anti-rejection drug could more effectively prevent acute rejection than Aza after renal transplantation,and has lower toxicity and side effect.
ABSTRACT
This article deals with the diagnostic values of IFAT and IEST in human filariasis with both frozen sections of Brugia malayi and Setaria cervi adult worms as antigens. The average positive and the false positive rates of IFAT with two antigens were 84.9-97.1%(45/53-102/105)and 2.9-9.7%(1/35-3/31) respectively, while no cross-reaction was observed in subjects infected with ascaris or hookworm. The average positive and the false positive rates of IEST with two antigens were 94.3-94.9% (99/105-56/59) and 0-2.9% (0/35-l/35) respectively. Both IFAT and IEST with two antigens for the diagnosis of human filariasis were considered to be of higher sensitivity and specificity, frozen sections of adult Setaria cervi being more economical and effective.
ABSTRACT
IEST, DGS-COPT and CV-COPT using lyophilized ova of schistosoma japonicum were performed on sera from 120 cases of schistosomiasis japonica, 120 cases of schis-tosomiasis japonica 3-8 years after being cured with praziquantel and 120 healthy individuals by single-blind method. The sensitivity and specificity of IEST was 91.7% and 95.8% respectively which were significantly higher than that of both DGS-COPT and CV-COPT. The negative conversion rate of cured patients was 70.8% with IEST, 80.8% with DGS-COPT and 81.7% with CV-COPT. The results showed that IEST has higher diagnostic value for schistosomiasis than both COPT. DGS-COPT has the same diagnostic value as CV-COPT, however, it was easy to perform and time-saving, thus it might be applied in the fields for practical purposes.
ABSTRACT
A new method of two-direction counter-immunoelectrophoresis (TD-CIEP and TD-ELACIEP) for detection of specific antigen and antibody of enzyme-dissociated schisto-some circulating immune complexes (SCIC) in infected rabbits and advanced schistosomia-sis cases was reported. Results showed that the detection rate was markedly increased in the enzyme-dissociated sera as compared with that of non-dissociated sera. The levels of antigen and antibodies were found to be correlated to the period and intensity of infection. The detected antigen was solely originated from the adult worm. Comparison of sensitivity of both methods showed that TD-ELACIEP was much more sensitive than TD-CIEP either for detection of antigen or antibodies. Of 54 sera of advanced schistosomiasis cases the detection rate of schistosome antigen or antibodies by TD-ELACIEP in enzyme-dissociated and non-dissociated serum samples was 50 and 25.9%, respectively. Only 9 cases( 16.7%) were COP positive with COP rate
