Figure 5. KV1-C peptide constricts rat CA in vivo.

Figure 5

A) An overview of the cranial window. A branch of middle cerebral artery (arrowhead) is analyzed for diameter changes. B) Representative images reveal the constrictor response of a middle cerebral artery branch to 30 µmol/L KV1-C peptide, but not to the same concentration of Scm peptide. C) Diameter responses of single arterial branches to Scm or KV1-C peptide. D) Percent change in diameter from baseline in response to 30 µmol/L Scm or KV1-C peptides or physiological salt solution (PSS). Scale bar, 5 min. **: Significant difference from PSS and Scm, P<0.01, n=5–7.
