We examined the changes in vascular permeability induced by inflammatory mediators in mouse skin by the Pontamine sky blue (PSB) leakage technique. Five min after i.v. administration of PSB, mediators or saline were injected (0.1 ml/site, s.c.) into the back. Sixty min later, the dye accumulated in the skin was determined colorimetrically. Plateletactivating factor (PAF, 45-180 pmol/site), 5-hydroxy-tryptamine (5-HT, 120-960 pmol/site), substance P (100-1, 000 pmol/site) and histamine (550-5, 500 pmol/site) produced dose-related increases in vascular permeability. The dose response curve induced by bradykinin (20-80 nmol/site) was bellshaped. Pretreatment with indomethacin significantly reduced the increase in vascular permeability elicited by the 5 substances tested. Coadministration of prostaglandin (PG) E2 partially reversed the inhibitory effect of indomethacin on the PAF- or histamine induced-increase in vascular permeability. Increases in vascular permeability induced by 5-HT, substance P and bradykinin were inhibited by NG-nitro-l-arginine methyl ester (L-NAME) and methylene blue, but not by D-NAME ; however, PAF-and histamine-induced increases in vascular permeability were not affected by L-NAME.These results suggest that eicosanoids may play a role in the effect of all 5 substances tested, and especially the increases in plasma extravasation induced by PAF and histamine are mediated by the production of PGE2, and that NO may play a role, at least partly, in the case of 5-HT, substance P and bradykinin.

助産師外来では妊娠生活指導、分娩に向けた準備などの他に精神的な関わりが必要になってくる場面が多くある。無脳症と診断され妊娠継続を希望した妊婦と関わり、妊娠生活を送っていく上で気持ちの変化や児への愛情が日々大きくなっていく様子を傍で見て、感じ、児を迎えるための準備を妊婦の気持ちに寄り添いながら行ってきた。助産師外来から関わりを持つことで、妊婦のニーズを把握し、看護に生かすことができ、それが満足のできる分娩にもつながっていく。今回の関わりを通して、助産師外来からハイリスク妊婦と関わっていくことの必要性や、外来での関わりが病棟での満足できる分娩につながっていくと考えられた。
