A current survey on the selenium status and coxsakievirus B infection in Keshan disease area, Heilongjiang Province

Objective To acquaint the situation of selenium nutrition level and coxsakievirus B(CVB) infection in Keshan disease(KD)patients in Heilongjiang province,and provide the evidence for taking the direction mell811rement$of KD contr01.Methods The subjeets were divided into three groups:disease area KD group, disease area control group,and non-disease area control group.We collected soil,food and blood,which were used to detect selenium content,and assay IgN antibody of CVB in plasma.The selenium content of blood was determined with hydride generation atomic fluorometry spectrometrie.The lgM antibody of CVB was measured with ELISA test Kit.Results Compared with those in non-disease areas,selenium content of soil,maize,wheat and bean(0.092 ±0.011,0.003±0.001,0.005±0.003,0.006±0.001)μg/L in disease area Welre significantly lower(t=17.007.8.551,15.842,12.109;all P 0.05).Conclusions Selenium deficiency and CVB infection still exist in KD area,Heilongjiang Province.
