Sequence of events in substance P-mediated plasma extravasation in rat skin

Using a blister model of inflammation in the rat hind footpad, we have studied the temporal and quantitative contribution of mast cell mediators and prostaglandins to substance P-induced plasma extravasation. In addition substance P-related peptides (neurokinin A, SP5-11 and SP1-7) were tested for their ability to induce a plasma extravasation response and the extent of histamine involvement to the response was determined. The present results...
