In 7 open-chest anesthetized mongrel dogs the left anterior descending coronary artery was occluded for 20 sec. Myocardial reactive hyperemia was recorded during air and oxygen breathings. The excess blood flow during the reactive hyperemia was smaller and the duration of the reactive hyperemia was shorter during oxygen breathing than during air breathing. It is suggested that the reduction of ...

In the course of studies on the effects of magnesium (Mg) depletion in the diet (0.001% Mg) on mature rats (10 week-old), it became apparent that females developed less hyperemia than males. In the females, the time of onset and severity of hyperemia were enhanced by castration, but not in the males. These data suggest that the development of hyperemia in Mg-deficient adult rats depends on the ...

OBJECTIVE To evaluate the diagnostic value of peripheral circulatory reactive hyperemia and serum levels of interleukin-6 (IL-6), IL-8, and tumor necrosis factor-alpha (TNF-alpha) in early-onset neonatal sepsis. METHODS Reactive hyperemia in the dorsal hand and serum levels of IL-6, IL-8, and TNF-alpha were studied in newborn infants (n = 32; gestational age 39 +/- 3 weeks) who had been admit...

introduction: in the absence of microvascular replantation or in crash injury cases in which obtaining an acceptable function is not possible, amputation of the injured finger seems to be the best treatment modality. some studies recommended leech therapy for this kind of injury after vascular repair to decrease venous congestion. case presentation: in this case report, the authors presented a ...

BACKGROUND Myocardial perfusion during adenosine-induced hyperemia is used both in clinical diagnosis of coronary heart disease and for scientific investigations of the myocardial microcirculation. The objective of this study was to clarify whether adenosine-induced hyperemia is dependent on endothelial NO production or is influenced by adrenergic mechanisms. METHODS AND RESULTS In 12 healthy...

PURPOSE The purpose of this study was to compare inflammatory events and graft characteristics 1 month and 6 months after conjunctival limbal autograft (CLAU) with and without intraoperative mitomycin C (MMC). METHODS This study included 69 eyes of 69 patient's eyes with pterygium. Clinical data concerning patient demography, preoperative examination including pterygium morphology, recurrence...

BACKGROUND Type 2 diabetes (T2DM) is associated with an increased risk of cardiovascular disease. This can be partly explained by large-artery dysfunction, which already occurs in prediabetes ("ticking clock hypothesis"). Whether a similar phenomenon also applies to microvascular dysfunction is not known. We therefore tested the hypothesis that microvascular dysfunction is already present in pr...
