Key result
C-type natriuretic peptide (CNP) caused significant concentration-dependent relaxations in isolated canine veins, whereas ANP caused no significant relaxation, demonstrating distinct biological roles.
CNP acts as a distinct relaxing factor in isolated peripheral canine veins, supporting its unique biological role in regulating cardiovascular tone compared to ANP.

Should not change practice; leaves open CNP's distinct role in human venous regulation.
Wei et al. (1993) studied Cardiovascular tone (isolated canine vessels). C-type natriuretic peptide (CNP) vs. Atrial natriuretic peptide (ANP) was evaluated on Isometric force/relaxation in an organ chamber. C-type natriuretic peptide (CNP) caused significant concentration-dependent relaxations in isolated canine veins, whereas ANP caused no significant relaxation, demonstrating distinct biological roles.
