RESUMEN
The content of zinc and copper in the hair of 321 persons was detected by an atomic absorption spectropolarimeter. The subjects included young healthy group (35 men, 30 women), middle aged healthy group (72 men, 18 women), arteriosclerosis group (81 men, 20 women), cerebral embolism group (23 men, 8 women) and its control group (23 men, 8 women). The ratio of zinc to copper in the hair of the persons suffered from cerebral embolism was obviously higher than that of healthy controls. By comparing the function of the susceptible factors in cerebral embolism with Feisher's determination analysis method, diastolic pressure was found to be 75.02 percent, the ratio of zinc to copper 16.32 percent. The diagnostic coincidence was found to be above 82 percent.
