The vasculature of rat isolated mesentery and small intestine was perfused with a gelatin-containing physiological salt solution (GPSS). When 5-hydroxytryptamine (5HT, 1 x 10(-4) M), or the calcium ionophore A23187 (1 x 10(-4) M), or 12-deoxyphorbol 13-phenylacetate (DOPPA, 1 x 10(-6) M), or 12-deoxyphorbol 13-phenylacetate 20-acetate (DOPPAA, 1 x 10(-6) M) or thymeleatoxin (TMX, 1 x 10(-6) M) was added to the GPSS for 5 min there was a gradual rise in perfusion pressure, whereas resiniferatoxin (RFX, 1 x 10(-6) M) was without effect. Pre-treatment of the tissue with the protein kinase C (PKC) inhibitor Ro 31-8220 (1 x 10(-6) M) significantly reduced the rise in perfusion pressure in response to 5HT, DOPPA, DOPPAA and TMX, but not that to A23187. Platelet-activating factor (PAF, 5 x 10(-6) M) caused an almost immediate but transient rise in perfusion pressure, followed by a more gradual rise, neither response being blocked by Ro 31-8220. When blood vessels of the mesentery alone were perfused with gelatin-free PSS, PAF caused a transient rise in perfusion pressure, but with no subsequent gradual rise over 5 min. After Ca(2+)-depletion this transient response was also absent. In contrast, when blood vessels were perfused with gelatin-free PSS, DOPPA and TMX still caused gradual rises in perfusion pressure, which were totally abolished by Ro 31-8220. TMX had no effect at all when the tissue was depleted of Ca2+, whereas the response to DOPPA was only partially reduced.(ABSTRACT TRUNCATED AT 250 WORDS)

PAF-86 film is electropolymerized (EP) by targeted monomer M1 tethered bifunctional carbozolyl moieties which not only serve in electron donation but also provide effective electrochemical (EC) active sites. The resulting PAF-86 film possesses a fairly compact surface, remarkable stability, efficient hole extraction capacity, and hole-transporting materials (HTMs) for inverted heterojunction perovskite solar cells (PSCs). Likewise, our investigation shows that PAF-86 film based perovskite solar cells (PSCs) retained about 80% power conversion efficiency (PCE) without encapsulation in air, and poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) based PSCs devices reduce to 4% under the same conditions. More impressively, the electropolymerization approach is convenient, controlled, and operated at ambient conditions which elude post heat-treatments and are appropriate for industrial application.
