Abstract

Thep resent work deals with the effects of extremely low frequency electromagnetic Thep resent work deals with the effects of extremely low frequency electromagnetic Thep resent work deals with the effects of extremely low frequency electromagnetic Thep resent work deals with the effects of extremely low frequency electromagnetic fields (ELF-EMF)o nb lood vessels permeability to non liposoluble substances of the fields (ELF-EMF) on blood vessels permeability to non liposoluble substances of the fields (ELF-EMF) on blood vessels permeability to non liposoluble substances of the fields (ELF-EMF) on blood vessels permeability to non liposoluble substances of the circumventricular organs (CVO) of adult rats. Male Wistar adult rats were exposed to ELF-EMF circumventricular organs (CVO) of adult rats. Male Wistar adult rats were exposed to ELF-EMF circumventricular organs (CVO) of adult rats. Male Wistar adult rats were exposed to ELF-EMF circumventricular organs (CVO) of adult rats. Male Wistar adult rats were exposed to ELF-EMF and vascular permeability to colloidal carbon was investigated with theu se of histological and vascular permeability to colloidal carbon was investigated with theu se of histological and vascular permeability to colloidal carbon was investigated with theu se of histological and vascular permeability to colloidal carbon was investigated with theu se of histological techniques. Results were compared to corresponding data from sham-exposeda nd control techniques.R esults were compared to corresponding data from sham-exposeda nd control techniques.R esults were compared to corresponding data from sham-exposeda nd control techniques.R esults were compared to corresponding data from sham-exposeda nd control groups of animals. Exposure to ELF-EMF increased theCVO vascular permeability to colloidal groups of animals. Exposure to ELF-EMF increased theCVO vascular permeability to colloidal groups of animals. Exposure to ELF-EMF increased theCVO vascular permeability to colloidal groups of animals. Exposure to ELF-EMF increased theCVO vascular permeability to colloidal carbon intravascularly injected, particularly in the subfornical organ, them edian eminence, the carbon intravascularly injected, particularly in the subfornical organ, them edian eminence, the carbon intravascularly injected, particularly in the subfornical organ, them edian eminence, the carbon intravascularly injected, particularly in the subfornical organ, them edian eminence, the pineal gland andthe area postrema. pineal gland andthe area postrema. pineal gland andthe area postrema. pineal gland andthe area postrema.

Potential antiinflammatory and immunomodulatory effects of statins in rheumatologic therapy

“…They have also been used as coadjuvants in depression [Carpenter, 2006] and pain treatment [Eccles, 2005; Thomas et al, 2007] and have been associated with progenitor cell differentiation in the endothelium, and angiogenesis as well [Tepper et al, 2004]. MF have been associated with stem cell differentiation in the central nervous system (CNS) [Feria‐Velasco et al, 1998; Arias‐Carrion et al, 2004]; they increase the blood–brain barrier (BBB) permeability in some brain areas [Salford et al, 1994; Gutiérrez‐Mercado et al, 2008]; and appear to be of some benefit in the treatment of some types of epileptic episodes [Ossenkopp and Cain, 1988; Seyhan and Canseven, 2006; Ransohoff, 2009]. However, the subject has been highly controversial since other authors have challenged the theory of MF effects upon the nervous system's biology [Preston et al, 1979; Fritze et al, 1997].…”

“…CVOs are specialized CNS structures located along the midline, immediately subjacent to the ependymal epithelium of the third and fourth ventricles. They have very diverse functions mainly related to the control of systemic metabolic processes, regulation of liquid intake, and regulation of renal, endocrine and cardiorespiratory functions, among others [Palkovits, 1987; Gross, 1992; Johnson and Gross, 1993; Gonzalez‐Marrero et al, 2007; Gutiérrez‐Mercado et al, 2008].…”
