    【Abstract】 Objective To investigate the clinical significance in detecting the β2-microglobulin in level in cerebrospinal fluid at in the children patients with viral encephalitis.Methods We detected β2-microglobrlin level in cerebrospinal fluid of children patients with viral encephalitis in cerebrospinal fluid with radio-immunity way.Results The results implied that the level of β2-microglobulin in cerebrospinal fluid at the early period of disease was obviously increased compared to the control, and was slowly correlated to the white blood cell count, level of protein, glucose and lactated hydrogenase in cerebrospinal fluid,but the correlation is no statistical significance,the results also implied that the level of β2-microglobulin was not correlated to the severity of the disease and was significantly positive ......
