title: [Effect of intravascular laser irradiation of blood and traditional Chinese medical therapy on immune function in senile cerebral infarction patients of kidney deficiency type].
abstract: OBJECTIVE
  To observe the effect of intravascular laser irradiation of blood (ILIB) therapy on cellular immunity, change of T-lymphocyte subsets and humoral immunity in senile cerebral infarction patients of Kidney deficiency type.
  
  
  METHODS
  Seventy-five patients were divided randomly into the ILIB group and the control group treated by conventional medicine (CM). Serum CD3, CD4, CD8, IgG, IgA, IgM, C3 and C4 levels of patients were determined before and after treatment for self-control and comparing between various groups and that of normal control.
  
  
  RESULTS
  Before treatment, in patients of both groups, the levels of CD3, CD4, CD4/CD8, C3 were all lower than normal levels significantly, C4 and IgM higher than normal (P < 0.05, P < 0.01), the level of IgG lowered in patients inclined to Kidney-Yang deficiency and raised in those inclined to Kidney-Yin deficiency (P < 0.01). After treatment, in the ILIB group, CD3, CD4 and CD4/CD8 raised significantly (P < 0.05, P < 0.01), IgG and C3 varied towards normal control (P < 0.01, P < 0.05), and C4 lowered but without significance. In the control group, the indexes changed also toward normal but without significance except the change of IgG (P < 0.05). As for IgA and IgM, marked changes were not found in both groups in comparison between before and after treatment.
  
  
  CONCLUSIONS
  ILIB therapy could bi-directionally regulate cellular and humoral immunity in senile cerebral infarction patients of Kidney deficiency type, which was similar to the function in supplementing Qi and invigorating Kidney of Chinese herbal medicine.
