Objective To observe the expression in sarcoma tissue,blood,salivaand urine of KSHV-encoded virus macrophage inflammatory protein vMIP-Ⅰ,vMIP-Ⅱ.Methods Genomic DNA was extracted from samples in 8 classic Kapsi' s sarcoma patients of Xinjiang,vMIP-Ⅰ and vMIP-Ⅱ gene were amplified by PCR.Results Genomic DNA were detected from sarcoma tissue,blood,saliva and urine of 8 classic Kapsi' s sarcoma patients,while vMIP-Ⅰ and vMIP-Ⅱ were amplified from all tissue samples,but the expression of vMIP-Ⅰ and vMIP-Ⅱ in blood,saliva and urine was negtive.Conclusions There is special expression of vMIP-Ⅰ and vMIP-Ⅱ in Kapsi' s sarcoma tissue.It provides a preliminary basis for further study of the mechanism of angiogenesis Kaposi's sarcoma.
