title: [Distribution of cytomegalovirus DNA in vascular tissues and the relationship between virus and atherosclersogenesis].
abstract: OBJECTIVE
  To explore the distribution of cytomegalovirus (CMV) in vascular tissues and the relationship between virus and atherosclerogenesis after CMV infecting mice.
  
  
  METHODS
  (1) C57 BL/6J Murine model of CMV infection was established by intraperitoneal injection of CMV lethiferous amount. (2) After 12 weeks of CMV infection, the sera, carotids, aorta, hearts and postcaval veins from the mice were collected under euthanasia. The tissues would be used to DNA extraction, PCR and pathological examination. (3) Interleukin-6 (IL-6) and monocyte chemotactic protein-1 (MCP-1) in serum were measured with ILELISA.
  
  
  RESULTS
  (1) The typical pathologic feature in 2 aorta samples of 6 mice infected by CMV was found and the mice uninfected by CMV did not show any pathologic change. (2) CMV DNA appeared in 6 aorta, 6 postcaval veins, 4 carotids and 4 heart tissues including endocardium, cardiac muscle and coronary artery from the CMV infected mice. CMV DNA was not found in the vascular and heart tissues from 6 mice uninfected by CMV. (3) The ELISA test showed the significant difference (Mann-Witney test of Nonparametric Test, P < 0.05) in serum IL-6 (Median among 25% and 75% percentile: 113.7 pg/ml vs. 49.77 pg/ml) and MCP-1 (Median among 25% and 75% percentile: 128.7 pg/ml vs. 45.36 pg/ml) between CMV infected mice and uninfected mice.
  
  
  CONCLUSIONS
  Cardiovascular cells are CMV latent reservoir in host body and CMV infection and the cytokines induced by CMV infection probably relate to atherosclerogenesis.
