This study was designed to directly quantify the effect of localized static magnetic field (SMF) exposure on the diameter of microvessels in adult rat skeletal muscle in vivo. Microvascular networks in the exteriorized rat spinotrapezius microvasculature were exposed to a localized, uniform 70 mT SMF for 15 min. Arteriolar vessel diameters were measured; and the extent of vessel contraction, microvascular tone, was calculated before exposure, immediately after exposure, and 15 and 30 min after…

Static Magnetic Field Versus Systemic Calcium Channel Blockade Effect on Microcirculation: Possible Mechanisms and Clinical Implementation.
TLDR
SMF can have a strong vasodilator property tailored to address diabetic, mainly NO-deficient, neural, and myogenic microvascular dysfunction, especially employing both SMFs' vasodilation synergy.
Subcutaneous Arteriolar Vasomotion Changes During and After ELF-EMF Exposure in Mice in Vivo
TLDR
It is suggested that ELF-EMF may have potential therapeutic use benefit for treating vascular disorders as well as biological effects of extremely low-frequency electromagnetic fields on microcirculation in conscious mice.
Chronic static magnetic field exposure alters microvessel enlargement resulting from surgical intervention.
TLDR
It is suggested that chronic SMF exposure can alter the adaptive microvascular remodeling response to mechanical injury, thus supporting the further study of chronic application of SMFs for the treatment of vascular pathologies involving the dysregulation of microv vascular structure.

TLDR
Augmentation of the arterial baroreflex capacity support NO-dependent vasodilation, by increased sensitivity of vessels to NO, is suggested to be a new physiological mechanism of BP buffering and microcirculatory control.
Effects of neck exposure to 5.5 mT static magnetic field on pharmacologically modulated blood pressure in conscious rabbits.
TLDR
The buffering effects of the SMF on increased hemodynamic variability under NE-induced high vascular tone and NIC-induced low vascular tone might be, in part, dependent on baroreflex pathways, which could modulate NE-mediated response in conjunction with Ca(2+) dynamics.
Effects of a moderate-intensity static magnetic field on VEGF-A stimulated endothelial capillary tubule formation in vitro.
TLDR
It is suggested that the application of SMF to intact or VEGF-A-stimulated vascular endothelial cells leads mainly to promote or enhance arteriogenesis in the peripheral part of the wells, where the spatial gradient increases relative to the central part.
A literature review: the effects of magnetic field exposure on blood flow and blood vessels in the microvasculature.
TLDR
Recommendations for future work include studies aimed at the cellular/mechanistic level, studies involving perfusion measurements both during and post-exposure, studies testing the effect of MFs on anesthetics, and investigation into the microcirculatory effects of MRI.
Extremely low frequency pulsed electromagnetic field designed for antinociception does not affect microvascular responsiveness to the vasodilator acetylcholine.
TLDR
It is suggested that there are no significant acute physiological effects of 225 microT PEMF after 30 and 60 min of exposure on peak blood flow, heart rate, and myogenic activity, but perhaps a small attenuation effect on anesthetic-induced respiratory depression.
Static magnetic field blood pressure buffering, baroreflex vs. vascular blood pressure control mechanism
  • J. Gmitrov
  • Medicine, Biology
    International journal of radiation biology
  • 2010
TLDR
The results suggest that verapamil-potentiated vascular blood pressure buffering mechanism was more effective than SMF- Potentiated baroreflex-mediated blood pressurebuffering mechanism, and a potential benefit of both approaches in cardiovascular conditions with abrupt high elevation in blood pressure.
Static Magnetic Field Effects on Impaired Peripheral Vasomotion in Conscious Rats
TLDR
It is suggested that SMF may have a regulatory effect on rhythmic vasomotion in the ischemic area by smoothing the Vasomotion amplitude in the early stage of the wound healing process.

Biphasic effects of static magnetic fields on cutaneous microcirculation in rabbits.
TLDR
It is suggested that SMF can modulate vascular tone due to biphasic modification of vasomotion in the cutaneous tissue, and significantly enhanced vasodilatation under noradrenaline-induced high vascular tone.
Biological effects of static magnetic fields on the microcirculatory blood flowin vivo: a preliminary report
TLDR
It is hypothesised that changes in blood flow before and after exposure to a magnetic field for 20 min represent rebound hyperaemia following reduced blood flow during exposure.
Effect of 0.25 T static magnetic field on microcirculation in rabbits.
TLDR
It is proposed that long exposure of a high level nonuniform SMF probably modifies microcirculatory homeostasis through modulation of the local release of endothelial neurohumoral and paracrine factors that act directly on the smooth muscle of the vascular wall, presumably by affecting ion channels or second messenger systems.
Acute effects of static magnetic fields on cutaneous microcirculation in rabbits.
TLDR
The results suggest that the SMF can modulate vascular tone due to vasomotion which may involve in clinical efficacy for refraining from neck and shoulder stiffness.
Local application of adenosine induces an increase of capillary diameter in skeletal muscle of anesthetized rabbits.
TLDR
Capillary diameter was larger during aortal occlusion in the presence of ADO than during control femoral artery pressures without ADO, even though capillary pressure was probably higher in the latter case.

Microvascular Blood Flow in the Normotensive and Spontaneously Hypertensive Rat
TLDR
Results indicate that the higher vascular resistance and corresponding lower blood flow of the SHR can be attributed in part to: 1) smaller arterial diameters, locally and/or neurally controlled in the second through fifth order arteries and structurally determined in the first order artery; and 2) a smaller number of arterial branches.
Modulatory effects of static magnetic fields on blood pressure in rabbits.
TLDR
Modulatory effects of SMF on BP might, in part, involve a feedback control system for alteration in NOS activity in conjunction with modulation of Ca(2+) dynamics.
High-intensity static magnetic fields modulate skin microcirculation and temperature in vivo.
TLDR
Skin blood flow and temperature decreased significantly during magnetic field exposure and recovered after removal of the animal from the magnet, and the rectal temperature showed a tendency to decrease while the animal was in the magnet.
Invited review: arteriolar smooth muscle mechanotransduction: Ca(2+) signaling pathways underlying myogenic reactivity.
TLDR
The smooth muscle of arterioles responds to an increase in intraluminal pressure with vasoconstriction and with vasodilation when pressure is decreased, and the purpose of this brief review is to summarize the current literature relating to Ca(2+) and the arteriolar myogenic response.
