subintimal

These sites were evident around blood vessels of the subintima, throughout the subintimal stroma and in the intima.

A guide wire is intentionally introduced in the subintimal space, after which balloon dilatation is performed to create a new lumen for the blood to flow through.

The positive cells were located close to blood vessels in leukocyte infiltrates and non infiltrated sites, and in more remote sites within the subintimal stroma (Fig.

There is also increased recruitment of neutrophils in RA, migrating from subintimal venules, across the synovium and into the synovial fluid where they can occur in large numbers.

Conclusion This study demonstrates the expression of available chemokine binding sites for CCL2, CCL3, CCL5 and CXCL8 on CD68 +macrophages in the subintimal and intimal layers of rheumatoid and nonrheumatoid synovia.

Surrounding the necrosis is a layer of palisading macrophages and fibroblasts, corresponding to the intimal layer in synovium and a cuff of connective tissue containing clusters of lymphocytes and plasma cells, corresponding to the subintimal zone in synovitis.

Similarly, in RA samples that possessed neutrophils, immunoreative CXCR1 and CXCR2 was displayed by these cells throughout the subintimal and intimal layers; the staining intensity for CXCR2 was more strong than for CXCR1 (Fig.
