demonstration using tranylcypromine, a similar demonstration by others, and a direct demonstration in which PGI2 was locally applied to injured vessels in hamster cheek pouch. Our data thus offer a different type of supporting evidence on the capacity of PGI2 to influence platelet aggregation in vivo. We have, in addition, extended previous data to another organ and another species, suggesting ...

Propagated vasodilation has been observed in the peripheral vasculature and may be significant in integrating the behavior of terminal arterioles and larger vessels. We have studied the characteristics of propagated vasodilation induced by acetylcholine in the microcirculation of the cheek pouch of the golden hamster. The technique of microionophoresis was used as a means of achieving relativel...
