IIistologic progression from normal through inflanmmtion, uniform hyperplasia, localized premalignant h...
متن کاملPropagated vasodilation in the microcirculation of the hamster cheek pouch.
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...
متن کاملFactors affecting hamster sarcoma growth in the cheek pouch.

متن کاملGender differences in microcirculation: Observation using the hamster cheek pouch
OBJECTIVES Estrogen has been shown to play an important protective role in non-reproductive systems, such as the cardiovascular system. Our aim was to observe gender differences in vivo with regard to the increase in macromolecular permeability and leukocyte-endothelium interaction induced by ischemia/reperfusion as well as in microvascular reactivity to vasoactive substances using the hamster ...
