2.STUDIES ON THE PROTECTIVE IMMUNITY OF Sj 60-90 KD IMMUNOGEN IN SCHISTOSOMA JAPONICUM
Chinese Journal of Schistosomiasis Control 1989;0(03):-
The 60-90 KD antigen of Schistosama japanicum isolated from SEA by SDS-PAGE was used to immunize female C57BL/6 mice viasubcutaneous injection route. Protective immunity against challenge infection with cercariae of S. japonicum was evaluated by the adult worm reduction rate, and the levels on humoral and cellular immunity in immunized mice.A high level of anti-SEA antibody litre in sera collected from immunized mice was detected by ELISA. The value of the adult worm reduction rate showed that there was no significant protective effect on challenge infection and no obvious difference beween immunized mice and non-immunized control groups. In addition, the data of T-cell proliferative response to ConA of spleen cells revealed that 60-90 KD antigen inhibited the response of T-cell to the mutagen. The possibility of induction of different results of immunity was discussed.

Purpose:To investigate the susceptible factors and treatment against cross infection in hospital of cancer patients.Methods:174 cases of cross infection in hospital of cancer patients from 1997 to 1999 were analyzed for infective site, infective agent and infectious bacteria. Results:174 cases of cross infection in hospital of cancer patients were found, which was 10.45% of the in paitents of the same period. The majority (108/174) had infection of tissues and organs within irradiation fields after radiotherapy. Respiratory tract infection rate was 76.43%. 16 cases (40.0%) were found to have secondary infection of digestive canal after chemotherapy in the 40 cases of infection of digestive canal. Bone marrow deression or chronic failure and long term decubitus were also causes of infection. In addition, mycotic infection was 43.42% (33/76) in bacteriological tests with bad prognosis.Conclusions:Cross infection in the hospital occurs that patients enfeebled by radiotherapy, chemotherapy, chronic bone marrow failure and long term decubitus. Attention should be paid to the possibility of mycotic cross infection in hospitals, as the prognosis could be quite serious. As soon as the diagnosis is confirmed, early and full dose treatment by anti mycotic drugs should be given.

Objective To research the effect of ulinastatin on T-cytoimmunity in patients with infertility undergoing laparoscopic surgery. Methods Forty patients scheduled for receiving laparoscopic surgery were equally randomized into two groups, ulinastatin group (Group U) and control group (Group C). Ulinastatin was given to patients in the Group U at a dose of 20 × 104 U before anesthetic. No ulinastatin was given to patients in the Group C. Patients′venous blood samples for T-lymphocyte subset (CD3+,CD3+CD4+,CD3+CD8+) and CD3+CD4+/ CD3+CD8+ ratio calculation were collected before the surgery (T0) and at 0 h (T1),1st day (T2),3rd day (T3) after the surgery. Results CD3+ had less difference at T1~3 compared with T0 in the Group C but raised obviously at T2~3 in the Group U. CD3+CD4+ were only raised at T3 compared with T0 but raised obviously at T2~3 in the Group U. CD3+CD8+ were raised obviously at T2~3 compared with T0 in the Group C but had less difference in the Group U. CD3+CD4+/CD3+CD8+ had less difference at T1~3 compared with T0 in the Group C but raised obviously at T3 in the Group U. Conclusion The application of ulinastatin in laparoscopic surgery could significantly produce protective effect on T-cytoimmunity.
