Because of the difficult availability of brain tissue samples, investigation of the relevant beta-receptor of brain is limited. In the present study, the density of beta-receptors in brain tissues and in circulating lymphocytes was measured by the method of radio-ligand receptor binding (RLBA), in brain injury or brain tumor and a correlation analysis was performed. Our results show that there is linear correlation between the beta-receptors in brain tissue and in peripheral blood lymphocytes (r= 0. 811 , P<0. 01) in cases of increased permeability of bloodbrain barrier during brain injury or brain tumor.展开更多
