本文检测56例病毒性心肌炎患儿血硒及其免疫功能,结果患儿血硒水平明显抵于对照,且受试组淋转低,T细胞亚群检测结果CD_4和CD_3降低,提示受某些因素影响,非克山病地区儿童可发生硒缺乏。硒缺乏通过影响细胞免疫功能促进病毒感染及病毒性心肌炎发病。 In this paper, 56 children with viral myocarditis serum selenium and immune function, the results of blood levels of selenium in children significantly arrived in control, and the test group leaching low, T-cell subsets CD_4 and CD_3 results of the test results suggest that by some Factors, non-Keshan disease may occur in children selenium deficiency. Selenium deficiency through the impact of cellular immune function to promote viral infection and viral myocarditis incidence.
