Abstract:
Objective To study the effect of red blood cells on the secretion of white blood cells modulating globulin in patients with cancer with a new immunological reaction experimental system. Methods Cancer cells (S180, 5?10~6/ml) or 0.2ml of NS or 0.2ml of white blood cells and 0.3ml of plasma were added to anticoagulant suspension of white blood cells treated by citric acid and incubated for 1h at 37℃. The content of globulin (g/L) was determined by Olympus AU100 detector method. 0.2ml of cancer cells was added to 0.2ml of whole blood cells and 0.3ml of plasma in the whole blood experimental group. 0.2ml of NS was added to 0.2ml of whole blood cells and 0.3ml of plasma in the control group. 0.2ml of cancer cells was added to 0.2ml of white blood cells and 0.3ml of plasma in the white blood cell isolation experimental group. 0.2ml of NS was added to 0.2ml of white blood cells and 0.3ml of plasma in the control group. Results Activation rate (0.31?0.09) of globulin in whole blood cell experimental group of patients with cancer was significantly decreased compared to that (0.39?0.14) in normal people. Red cell adhesion rate (0.09?0.08) of globulin in control group was also significantly decreased compared to that (0.29?0.14) in normal people. Conclusion The results of our study indicate that the new experimental system can be used for detection of red blood cell-modulating globulin. The function of red blood cells in modulating globulin of patients with cancer is decreased.
