During the course of a study of skin blood flow under applied external pressure, it became apparent that decreasing blood flow by loading the skin surface reveals problems that are fundamental to the method of laser Doppler flowmetry. These problems have to do with the fact that the laser Doppler is extremely sensitive to red cell motion of any kind, whether associated with the ordered red cell...

1. The objective of this study was to investigate whether the luteal phase of the menstrual cycle differs from the follicular phase by the development of a state of general vascular relaxation. 2. Once in the follicular and once in the luteal phase of the menstrual cycle, we measured by non-invasive techniques: arterial blood pressure (by finger blood pressure measurements), vascular tone (by p...

OBJECTIVE This study investigated the effects of buflomedil and pentoxifylline, both of which are used in reconstructive surgery of hamster skin flap microcirculation, and evaluated the skin flap survival rate by orthogonal polarization spectral imaging. METHOD Twenty-four adult male Syrian golden hamsters were divided into three groups: a control (C, 0.1 ml 0.9% saline), buflomedil (B, 3 mg/...

Diabetes mellitus increases the risk for disorders that result in more frequent hospitalizations, longer in-patient stays, and increased morbidity and mortality. The incidence and severity of coronary artery disease, cerebrovascular disease, and peripheral artery macrovascular and microvascular diseases are greater in diabetics than in nondiabetics. Diabetic foot wounds are the single greatest ...
