Objective: To explore the role of i NOS( inducible nitric oxide synthase) and VEGF-C( vascular endothelial growth factor-C) in the lymphatic signal transduction pathway,with a goal to provide new targets for the treatment of cervical cancer. Methods: Tissue sections from 65 patients( 55 cervical squamous cell carcinoma,10 normal cervical tissues) were examined immunohistochemically( SP method) for protein expression of i NOS and VEGF-C.LVD( lymphatic vessel density) was counted by endothelial cells immuno-s...
