Abstract:
:Peptide 6A, a degradation of B beta chain of fibrinogen, is known to increase coronary and femoral blood flow. In this study, we examined the effects of peptide 32, an analogue of peptide 6A on coronary blood flow in anesthetized dogs. Intracoronary administration of equimolar amounts of peptide 32 and peptide 6A showed a greater (p < 0.05) increase in blood flow with peptide 32. Intravenous administration of peptide 32 also resulted in greater and longer-lasting increase in coronary blood flow. The greater blood flow enhancing effect of peptide 32 than that of peptide 6A may relate to absence of its degradation by angiotensin converting enzyme.
