Methods Flow cytometry was used to detect the NK cells absolute counting,expression of NKG2D of the NK cells in peripheral blood,and the ligand MICA/B in tissues.

The effect of interleukin-2 (IL-2) synergized with IL-18 to enhance activities of natural killer cells;

Linkage of the genes controlling natural killer cell activity to HLA-B;

Effects of specnuezhenide on the proliferation ability of lymphocytes and cytotoxicity of natural killer cells in murine splenocytes in vitro;

So,study on immune state of T cells and NK cells in maternal-fetal interface and maternal circulating blood can help to explore the mechanisms of immunotolerance during normal pregnancy and those pathological pregnancies that severely influence the pregnancy outcomes.

Methods:The mice injuryed by bacillus Calmette and Guerin(BCG) plus lipopolysaccharide(LPS) were treated by the 3 doses of Qingqi granules,control with the Thymosin α_1,it was observed that effects of Qingqi granules on NK cell,IL-2 and pathology changes of the mice liver.

Sorafenib induces aggregation of macrophages and natural killer cells in hepatocellular carcinoma rats

Objective To explore the changes and significance of activity of natural killer cells in patients with chronic heart failure(CHF).

[Objective] To explore the change and significance of activity of natural killer cells in patients with congestive heart failure(CHF).

Objective To evaluate the distribution of active T cells and nature killer cells (NK cells),as well as the interferon-γ(γ-IFN) level in tuberculous pleural effusions and malignant ones.

Objective: To evaluate the effects of Total Infusion Vein Anesthesia(TIVA)on T lymphocyte subsets and NK cells in breast cancer patients undergoing radical mammotomy with or with out chemicaltherapy preoperation, and to detect the micrometastases status in peripheral blood of those patients by reverse transcripition-polymerise chain reaction( RT PCR).

However, the effect of BCG on natural killer cells (NK cells) is still not well known.
