Influence of Agents Used for Topical Wound Treatment on Phagocyte Stimulation and Fibroblast Growth
Wound healing has always been a fascinating phenomenon for physicians and surgeons. Wounds usually close by forming new granulation tissue, contracting, and re-epithelializing. Before granulation begins, polymor-phonuclear leukocytes (PMNs) and monocytes/macrophages (MCs) are chemotactically attracted to sites of injury. Upon contact with various stimuli in the wound including bioactive lipids, complement components, certain cytokines, e.g., tumor necrosis factor-α (TNF-α) [1], granulocyte/ monocyte-colony stimulating factor (GM-CSF), interferon-γ (IFN-γ), and interleukin-8, and particles such as microorganisms, phagocytes respond by a respiratory burst consisting of a markedly enhanced upt…
Soluble intercellular adhesion molecule-1 levels in patients with psoriasis.
A newly developed ELISA was used to detect and quantify the presence of a soluble form of intercellular adhesion molecule-1 (sICAM-1) in the circulation of healthy individuals compared with patients with psoriasis vulgaris. Seventeen psoriatic patients were studied. The extent of skin lesions was rated by the psoriasis area and severity index (PASI). Seventeen age- and sex-matched healthy individuals served as controls. Serum levels were measured by an ELISA technique utilizing an anti-ICAM-1 murine monoclonal antibody bound to the solid phase, and a second, peroxidase-conjugated monoclonal antibody reacting with sICAM-1. Serum levels in controls were 358.8 +/- 87.9 ng/ml sICAM-1, and 480.5…
