RESUMO

To study the relationship between serum Pre-S1 antigen and HBV DNA, serum Pre-S1 antigen and HBV DNA marker in 229 patients positive for HbsAg were detected by using ELISA method and compared. It was found that both Pre-S1 antigen and HbeAg were correlated with HBV DNA with the coefficient being 0. 9812 and could be used to reflect the existence or reproduction of HBV DNA well. Although there was statistical correlation between them, their clinical implication was not completely the same. Therefore, a conclusion was drawn that combined detection of Pre-S1 antigen, HBV and HBV DNA in the patients with different kinds of HBV infection was helpful to clinical diagnosis, therapeutic effect evaluation and prognosis judgement.

RESUMO

Immunosuppressive activities have been found in the culture supernatant of four leukemiacell lines and in the sera of four patients with leukemia. The inhibitors suppressed PHA-p in-duced lymphocytes proliferation and IL-2 production and responsiveness of T cells to IL-2, butno inhibitory activity was observed in the culture supernatant of 2BS cell line or in the sera ofnormal humam. The culture supernatant of tumor cell lines was not cytoxic. The result of PAGEshows: the molecular weight of TDSF from HL-60 human promyelocytic leukemia is about87KD. It is protein in chemical nature. The synthesis and sercretion of TDSF were partially in-hibited by drugs of anti-acute non-lymphocytic leukemia.
