The cell surface phenotype of peripheral blood lymphocytes in patients with systemic lupus erythematosus (SLE) was studied with the anti-T4+, T8+ and T4+2H4+ monoclonal antibodies by flow cytometry. 13 patients with active SLE had a markedly low percentage of T4+2H4+ cells but had normal percentage of T8+ cells. Our results reveal that the influence of T(More)
PURPOSE Current data regarding association between ERCC1 polymorphisms and the risk of head and neck squamous cell carcinomas (HNSCC) have shown controversial results. The current study aims to achieve a more accurate estimation of the association between two well-characterized ERCC1 polymorphisms (rs3212986 and rs11615) and HNSCC risk by a meta-analysis of(More)
Soluble interleukin 2 receptor (SIL-2R) levels in serum appear to reflect the status of lymphocytic activation and proliferation. We examined the levels of serum SIL-2R in 65 patients with diffuse connective tissue diseases by using ELISA method. The mean levels of serum SIL-2R were respectively 0.46 U/L, 0.53 U/L, 0.46 U/L in systemic lupus erythematosus(More)
115 plasma exchange (PE) procedures were performed in 27 patients using the Haemonetics V50 plasmapheresis system 20 patients improved; among them 15 improved remarkably. Adverse reactions were observed 30 times (26.1%). PE showed beneficial effects in certain disease states which did not respond to conventional treatment or traditionally known therapeutic(More)
To investigate effects and possible mechanism of Ro 20-1724, a PDE4 inhibitor, on long-time learning and memory ability following repeated ketamine exposure in immature rats. Methods: Sixty 21-day-old SD rats were randomly divided into five groups (n = 12): C: Normal control group, S: Saline control group, K: Ketamine, K + Ro: Ketamine + Ro 20-1724, K + E:(More)
28 cases of hemophilia were examined for HCV infection status by using the Kehua anti-HCV ELISA kit of second generation. It was found that the infection rate was 78.5% and the infection rate was even higher with patients who had received transfusions or preparations of coagulatory factors. 10 families of 15 patients were also investigated. It was found(More)
Changes of blood coagulation in 32 cases of SLE were investigated. Abnormalities frequently found were elevation of blood fibrinogen, FDP, V111R: Ag levels, prolonged or shortened KPTT time, and depressed AT-III value. Half of the patients with SLE showed laboratory changes compatible with the diagnostic criteria of DIC, but acute DIC was encountered(More)
