[Study on erythrocytic immune function in diarrhea patients with spleen deficiency]

The erythrocytic immune function of 40 cases of patients with Spleen Deficiency (SD) and 20 cases of the normal control group were observed, and the former were subdivide into diarrhea group and non-diarrhea group. The results showed that the rosette rate of red cell C3b receptor (C3b-RR) in the SD patients was significantly lower than that of normal group and the rosette rate of red cell immune complex (IC-R) was significantly higher than that of normal group (P < 0.01); the C3b-RR in the diarrhea group was markedly lower than the non-diarrhea group, tce IC-R in the diarrhea group was markedly higher than the non-diarrhea group (P < 0.01), C3b -RR and IC-R correlated positively or negatively to the absorptivity of D-xylose hemoglobin, red blood cell and plasma albumin (P < 0.01). The results pointed out that the mechanism for the reduction of erythrocytic immune function was that the malnutrition in SD patients lowered the C3b receptors or damaged them or reduced their activity. The degree of malabsorption and systemic dysfunction in the diarrhea group was more serious, the erythrocytic immune function in the SD patient was lower.
