[Influence of smoking on red cell immune functions in highland adult men]

Formations of red cell C3b receptor rosette, red cell immune complex and helping tumour red cell rosette were assayed in 194 smokers and 66 non-smokers. Results showed red cell C3b receptor rosette and helping tumour red cell rosette formation in smokers was lower than in non-smokers (P < 0.01 and P > 0.05, respectively), but red cell immune complex formation in smokers was higher than in non-smokers. Red cell C3b rosette formation decreased with the quantity and duration of smoking. It suggested heavily smoking for a long period could influence the capabilities of red cell to clear out immune complex and to adhere and attack the tumour cells.
