[Relation of tongue color changes and red-cell immune adherence activity in patients with malignant bone tumor]

This article presents that preliminary study on the changes of the tongue colour and the red-cell immune adherence (RCIA) activity in 40 patients with malignant bone tumor, as compared with 40 healthy persons. The results showed that the rate of erythrocyte C3b receptor yeast rosette were no statistically significant different between the pink and the crimson tongues in the bone tumor group and control group (P greater than 0.05). It appeared RCIA activity was no depression in the patients with malignant bone tumor during pink and crimson tongue. In the bone tumor group with the pale and the cyanotic tongues, the rate of erythrocyte C3b receptor yeast rosette and erythrocyte immune complex rosette was significantly lower than that of the control group (P less than 0.05, P less than 0.01). It appeared that RCIA activity in these patients was markedly impaired. The authors suggested that the tongue colour changes in the patients with malignant bone tumors could roughly reflect the level of RCIA activity. This phenomenon is beneficially to predict the body capacity against the malignant tumor.
