Blood Flow Velocity

Bioelectrochemistry (Amsterdam, Netherlands)

Acute microhemodynamic effects of static and alternating magnetic fields at a threshold level were investigated on modulating the muscle capillary mirocirculation in pentobarbital-anesthetized mice. The skin in a tibialis anterior was circularly removed with 1.5 mm diameter for intravital-microscopic recording of the capillary blood velocity in the tibialis anterior muscle. Fluorescein isothiocyanate (FITC)-labeled dextran (MW 150 kDa) was used for an in vivo fluorescent plasma marker of the muscle capillaries.

Post-ischaemic flow mediated dilation of peripheral arteries (FMD) is transiently reduced during mental stress. This experiment was aimed at assessing whether hypnosis, which is a powerful relaxation technique, modulated the FMD response to mental stress in subjects with different hypnotic susceptibility. Results showed that hypnotic relaxation prevented the expected stress-related reduction of FMD only in highly hypnotizable subjects, suggesting a protective role of hypnotisability against vascular damage.

PURPOSE: It has been reported that mental stress is an independent risk factor for cardiovascular events and impairs coronary circulation. Lavender aromatherapy, one of the most popular complementary treatments, is recognized as a beneficial mental relaxation therapy. However, no study has examined the effect of this therapy on coronary circulation. We aimed to assess the effect of lavender aromatherapy on coronary circulation by measuring coronary flow velocity reserve (CFVR) with noninvasive transthoracic Doppler echocardiography (TTDE).

Meditative practices typically require several coordinated cognitive activities. This study measured changes in cerebral blood flow during "verbal" based meditation by Franciscan nuns involving the internal repetition of a particular phrase. These results are compared with those we previously described in eight Buddhist meditators who use a type of "visualization" technique. Three experienced practitioners of verbal meditation were injected via i.v. at rest with 260 MBq of Tc-99m HMPAO and scanned 30 min. later on a triple head SPECT camera for 45 min.

OBJECTIVE: We hypothesized that simvastatin may reduce adiponectin levels and insulin sensitivity in hypercholesterolemic patients. RESEARCH DESIGN AND METHODS: This was a randomized, double-blind, placebo-controlled, parallel study. Age, sex, and BMI were matched. Thirty-two patients were given placebo, and 30, 32, 31, and 31 patients were given daily 10, 20, 40, and 80 mg simvastatin, respectively, during a 2-month treatment period.

Recently we showed that the Pennes bioheat transfer equation was not adequate to quantify mm wave heating of the skin at high blood flow rates. To do so, it is necessary to incorporate an "effective" thermal conductivity to obtain a hybrid bioheat equation (HBHE). The main aim of this study was to determine the relationship between non-specific tissue blood flow in a homogeneous unilayer model and dermal blood flow in multilayer models providing that the skin surface temperatures before and following mm wave exposure were the same.

OBJECTIVE: An influence on organ-associated blood flow is considered as a possible mechanism of action of reflex zone massage of the feet (FRZM) therapy. In the present study we investigated whether changes in intestinal blood flow can be achieved by FRZM. MATERIAL AND METHODS: 32 healthy adults (19 women and 13 men) were randomly assigned to the treatment or the placebo group. Subjects of the treatment group received foot massage on the zones assigned to the intestines and those of the placebo group received massage on zones unrelated to the intestines.

OBJECTIVES: To examine and compare the effects of massage and matrix rhythm therapy in young women on the peripheral blood circulation. DESIGN: Randomized, double-blind, controlled trial. SETTING: Pamukkale University in Denizli, Turkey. PATIENTS: Fifteen healthy women age 19-23 years. INTERVENTION: Matrix rhythm therapy was applied to the left lower extremity for a single 30-minute session. At least 1 week later, massage was applied to the left lower extremity for 30 minutes in a single session. The same physiotherapist applied both sessions.
