2. Figure 1
Effects on inflammatory edema of the galanin-peptide-family. (a) Edema formation was induced by i.d. injection of SP (300pmol) and CGRP (10pmol), and the effect of coinjected salbutamol, endothelin-1 (n=4), and galanin peptides (n=6) is shown. Results are expressed as plasma extravasation (μl/g), mean±SEM measured by the 125I-BSA method. Responses that are significantly different from the corresponding SP+CGRP-treated sites are shown (*P<0.05, **P<0.01; Dunnett's). (b) Edema formation was induced by histamine (3nmol) and CGRP (10pmol), and the effect of coinjected galanin (3pmol) is shown. Results are expressed as plasma extravasation (μl/g), mean±SEM (n=4) measured by the 125I-BSA method. Responses that are significantly different from the corresponding histamine+CGRP-treated sites (**P<0.01; Dunnett's).

3. Figure 2
The dose-related effect of galanin on edema formation induced by i.d. injected SP (300pmol) with CGRP (10pmol). The response to increasing doses of galanin (0.1–10pmol) coinjected with SP+CGRP is shown as % inhibition (mean±SEM.) of edema formation measured by the 125I-BSA method. (n=10). Responses that are significantly different from the corresponding SP+CGRP-treated sites are shown (**P<0.01; Dunnett's).

4. Figure 3
Effect of GALP on inflammatory edema. Edema formation was induced in response to i.d. injected SP (300pmol) with CGRP (10pmol). The response in increasing doses of (a) GALP (1–60) (n=6) and (b) GALP (3–32) (n=8) coinjected with SP+CGRP is shown as % inhibition (mean±SEM.) of edema formation measured by the 125I-BSA method. Responses that are significantly different from the corresponding SP+CGRP-treated sites are shown (*P<0.05, **P<0.01; Dunnett's). (c) The effect of GALP (3–32) (10pmol) on plasma extravasation induced by SP+CGRP as observed by Evans Blue. Note that the intensity of blueing to SP+CGRP is reduced in the presence of GALP (3–32). GALP (3–32) alone had no effect when compared to vehicle.

5. Figure 4
The dose-related effect of galanin and GALP on blood flow. The dose–response effect of (a) galanin (n=8) and (b) GALP (3–32) (n=10) is shown as decrease in % clearance (mean±SEM) compared with vehicle (Tyrode-injected) skin. Results that are significantly different from Tyrode-injected sites are shown (*P<0.05; **P<0.01).

6. Figure 5
Effect of galanin and GALP peptides on blood flow in cutaneous dorsal microvasculature. The responses of salbutamol and ET-1 as negative and positive controls, respectively, are shown alongside responses of the most potent concentration (according to Figure 4) of galanin and GALP peptides (GALP (1–60), GALP (1–32), and GALP (3–32)). Responses are shown as decrease in % clearance (mean±SEM) compared with vehicle (Tyrode-injected) skin (n=8). Results that are significantly different from clearance at Tyrode-injected sites are shown (**P<0.01).
