[A preliminary study on the red cell immune function in blood stasis syndrome in traditional Chinese medicine]

20 patients with blood stasis syndrome (BSS), 20 patients with non-blood stasis syndrome (NBSS), and 17 normal subjects were measured by tests of RBC-C3b receptor rosette and RBC immune complex rosette. The rates of RBC-C3b receptor rosette formation (RBC-C3b RR, %) in BSS group, NBSS group and normal subjects were 20.90 +/- 4.02, 12.88 +/- 3.29 and 16.74 +/- 4.13 (P less than 0.01) respectively. The rates of RBC immune complex rosette formation (RBC-IC R, %) in the three groups were respectively 8.28 +/- 3.68, 7.73 +/- 2.48 and 7.41 +/- 2.43 (P less than 0.05). RBC-C3b RR was correlated to RBC-IC R in the normal subjects (r = 0.695, P less than 0.001). In patients with the same disease, RBC-C3b RR between the two syndromes (BSS and NBSS) was also very significantly different (P less than 0.01). This study suggested that there are variations on red cell immune function in BSS patients, and also provided an evidence that different syndromes of traditional Chinese medicine exist in diseases.
