    Photodynamic Therapy of Skin Cancers: A New Therapeutic Alternative?

    A photodynamic reaction is the excitation of a photosensitizer, mainly porphyrin derivatives, by visible light emitted by lamps or lasers in the presence of oxygen resulting in the generation of reactive oxyge...

    Current Evidence on a Pathophysiological Function of Leukocyte/Endothelial Interactions in Cerebral Ischemia

    Accumulation of leukocytes, particularly of polymorphonuclear neutrophils (PMNLs), is considered as an important response in tissue injury or infection. Recent investigations in a variety of organs, such as bo...

    Leukocyte/Endothelial Interactions and Blood-Brain Barrier Permeability in Rats During Cerebral Superfusion with LTB4

    The experimental study analyses the vasomotor response (change of diameter of pial arterioles and venules), and blood-brain barrier function of the pia-arachnoidea at the rat brain surface before, during and a...

    White Blood Cell Behavior in the Cerebral Microcirculation

    The role of white blood cells in acute cerebral disorders such as ischemia, stroke, or inflammation is not understood. Activated neutrophils might be involved, for example, in damage to the cerebrovascular end...

    Effect of Stimulation of Leukocyte Chemotaxis by fMLP on White Blood Cell Behaviour in the Microcirculation of Rat Brain

    The role of white blood cells in acute cerebral disorders such as ischemia or stroke is still unclear. Therefore, in the present study we investigated the effects of the leukotaxin n-formyl-methionyl-leucylphe...
