Laser Doppler perfusion monitoring of skin blood flow at different depths in finger and arm upon local heating.

The purpose of the study was to elucidate the vasodilatory response to local heating of the skin at two depths in two locations. To accomplish this, we measured skin blood flow in 12 healthy subjects using laser Doppler perfusion monitoring. A probe with two fibers separated 0.

Sympathetic skin vasoconstriction--further evaluation using laser Doppler techniques.

The aim of this study was to quantify the reflex sympathetic vasoconstriction in skin at different depths. Twenty healthy subjects were studied. Finger skin blood flow was measured using laser Doppler perfusion imaging (LDPI) and laser Doppler perfusion monitoring (LDPM).

Age-induced changes in the enteric nervous system in the mouse.

The enteric nervous system of the murine gut was investigated by immunocytochemistry in 1-, 3-, 12- and 24-month-old mice, using protein gene product 9.5, a general marker for nerve elements. Myenteric and submucosal plexi were quantified by computerized image analysis.
