1 Prostaglandin E(1) and bradykinin exert synergistic effects on vascular permeability in rat skin and in rat paws. Prostaglandin E(2) is inactive in this respect.2 Prostaglandin F(2alpha) reduces the bradykinin response in rat skin but not in rat paws. It also markedly reduces the response of the skin to dextran, 5-hydroxytryptamine and histamine.3 Prostaglandin E(1) and dextran exert synergistic effects in rat skin when threshold doses of each agent are used.4 Rats genetically resistant to dextran fail to respond to intradermal dextran in the presence of prostaglandin E(1).
前列腺素E(1)和缓激肽对大鼠皮肤和大鼠爪的血管通透性有协同作用。前列腺素E(2)在这方面无活性。
前列腺素F(2α)可降低大鼠皮肤而非大鼠爪对缓激肽的反应。它还能显著降低皮肤对右旋糖酐、5-羟色胺和组胺的反应。
当使用每种药物的阈剂量时,前列腺素E(1)和右旋糖酐在大鼠皮肤中产生协同作用。
对右旋糖酐具有遗传抗性的大鼠在存在前列腺素E(1)的情况下对皮内注射右旋糖酐无反应。
