ABSTRACT
El Zingiber officinale Rosc. (jengibre) es una especie que se ha utilizado por el hombre con diversos fines. Se estudió el efecto in vitro de una solución acuosa del rizoma de esta planta sobre los linfocitos de 30 donantes voluntarios de sangre y de 30 enfermos con diagnóstico de inmunodeficiencia celular, mediante la prueba de transformación linfoblástica, con el empleo de timidina tritiada, la técnica de formación de roseta activa y el ultramicrométodo inmunocitoquímico (UMICIQ). No se hallaron diferencias estadísticamente significativas entre las condiciones experimentales sin jengibre y con jengibre, con diluciones de este desde 1:2 hasta 1:2048 en la prueba de transformación linfoblástica. En la roseta activa y en los marcadores de activación HLA-DR y CD25 no se observaron diferencias estadísticamente significativas entre los linfocitos sin jengibre y los cultivados con la dilución 1:128, tanto en los donantes sanos como los enfermos
The Zingiber officinale Rosc (ginger) is a species used by man to different purposes. The in vitro effect of a aqueous solution from the rhizome of this plant on the lymphocytes of 30 volunteer blood donors and of 30 patients diagnosed with cellular immunodeficiency was studied by the lymphoblastic transformation test using tritiated thymidine, the technique of the rosette active formation and the immunocytochemical ultramicromethod (UMICIQ). There were not statistically significant differences among the experimental conditions with and without ginger with dilutions from 1:2 to 1:128 in the lymphoblastic transformation test. In the active rosette and in markers of the HLA-DR and CD25 activation there weren't statistically significant differences among lymphocytes without ginger and those cultured with a dilution 1:128 for healthy donors and for the patients

Objective To observe the changes of platelet activation markers in newborn infants with hyperbilirubinemia,and its relationship with myocardial enzymes and clinical significance.Methods Thirty neonates with hyperbilirubinemia were selected as observation group,and 15 health newborns were served as normal control group.In the morning,1 mL fasting blood in the femoral vein was collected from the patients in both groups,and 20 g/L EDTA-Na2 0.1 mL anticoagulant was added with a gentle shake.CD41-FITC 10 ?L was injected into two test tubes,with IgG1-PE and CD62-PE reagent 10 ?L added,diluted liquid 200 ?L PBS,and with 5 ?L whole blood,under dark room temperature for 15 minutes.Negative control tubes(CD41-FITC plus IgG1-PE) were applied to adjust voltage,the flow cytometry was used to determine CD62-PE.Myocardial enzymes and liver function were measured by automatic biochemistry analyzer.Results The levels of platelet activation markers in observation group were significantly higher than that in the normal control group(P
ABSTRACT
Objective To study the function of immunocytes in synovial fluid and the mechanisms of immune function disorder in patients with rheumatoid arthritis(RA).Methods The synovial fluid of 20 patients with RA and 10 healthy amputees because of traumatism in the affiliated hospital of Zhejiang university were collected in this syudy.Monoclonal antibodies against CD28,CD154(CD40L),CD80,CD86,CD40,CD69,CD25,HLA-DR,CD71 were used for flow cytometry and the expressions of costimulatory molecule CD28,CD154,CD80,CD86,CD40 on immunocytes and lymphocyte activation markers CD69,CD25,HLA-DR,CD71 in synovial fliud were studied in these patients.We also used enzyme linked immunosorbent assay(ELISA) to detect the cytokines level of Th1 cell including interleukine 2(IL-2),interferon-gamma(IFN-?) and those of Th2 cell including interleukine 6(IL-6),interleukine 10(IL-10) in the synovial fliud.Results Compared with control group,the expressions of CD80[(2.09?0.59)%vs(0.67?0.57)%,P
