RESUMO
Objective To explore the immunologic regulation of the bifidobacterium adolescence cell wall(BCW) on function of macrophage in mice and tumor inhibition of BCW on human transitional cell carcinoma of bladder(BTCC) outside of body.Methods BCW wereinjected into abdomen of KM mice,the level of IL-1,IL12 and TNF-?which produced by macrophage was determined by ELISA reagent box.The role of tumor inhibition was determined by MTT method.Results The level of IL-1,IL12 and TNF-?of BCW injection group was higher than of control group(P
RESUMO
<p><b>OBJECTIVE</b>To study the expressions of survivin, PTEN and their relationships with tissue grade and pathology stage in prostatic carcinoma (PCa).</p><p><b>METHODS</b>The immunohistological staining was used to evaluated the expressions of survivin protein and PTEN in 43 case of prostatic carcinoma (PCa) and 5 cases of benign prostatic hyperplasia (BPH).</p><p><b>RESULTS</b>The positive rate of survivin protein was 81.40%. Expression of survivin protein in 5 case of BPH was negative. The positive rate of PTEN was 30.23%, and the higher the grade and the clinical stage of tumors were, the lower the expression of PTEN was, PTEN of 5 case of BPH was positive.</p><p><b>CONCLUSION</b>The positively correlation was found between the abnormal expressions of survivin protein, PTEN and the biological behavior of prostatic carcinoma (PCa). Detection of survivin combined with PTEN is valuable for diagnosing PCa, and evaluating malignancy extent and prognosis.</p>
