Expression of neuropeptide Y receptors mRNA and protein in human brain vessels and cerebromicrovascular cells in culture. (1/432)

Neuropeptide Y (NPY) has been suggested as an important regulator of CBF. However, except for the presence of Y1 receptors in large cerebral arteries, little is known about its possible sites of action on brain vessels. In this study, we sought to identify the NPY receptors present in the human cerebrovascular bed. Specific Y1 receptor binding sites, localized on the smooth muscle of human pial vessels and potently competed by NPY, polypeptide YY (PYY), and the selective Y1 receptor antagonist BIBP 3226, were identified by quantitative radioautography of the Y1 radioligand [125I]-[Leu31, Pro34]-PYY. In contrast, no specific binding of the Y2-([125I]-PYY3-36) and Y4/Y5-(125I-human pancreatic polypeptide [hPP]) radioligands could be detected. By in situ hybridization, expression of Y1 receptor mRNA was restricted to the smooth muscle layer of pial vessels, whereas no specific signals were detected for either Y2, Y4, or Y5 receptors. Similarly, using reverse transcriptase-polymerase chain reaction (RT-PCR), mRNA for Y1 but not Y2, Y4, or Y5 receptors was consistently detected in isolated human pial vessels, intracortical microvessels, and capillaries. In human brain microvascular cells in culture, PCR products for the Y1 receptors were exclusively found in the smooth muscle cells. In cultures of human brain astrocytes, a cell type that associates intimately with brain microvessels, PCR products for Y1, Y2, and Y4 but not Y5 receptors were identified. Finally, NPY significantly inhibited the forskolin-induced cAMP production in smooth muscle but not in endothelial cell cultures. We conclude that smooth muscle Y1 receptors are the primary if not exclusive NPY receptors associated with human brain extraparenchymal and intraparenchymal blood vessels, where they most likely mediate cerebral vasoconstriction.  (+info)

Language outcome following multiple subpial transection for Landau-Kleffner syndrome. (2/432)

Landau-Kleffner syndrome is an acquired epileptic aphasia occurring in normal children who lose previously acquired speech and language abilities. Although some children recover some of these abilities, many children with Landau-Kleffner syndrome have significant language impairments that persist. Multiple subpial transection is a surgical technique that has been proposed as an appropriate treatment for Landau-Kleffner syndrome in that it is designed to eliminate the capacity of cortical tissue to generate seizures or subclinical epileptiform activity, while preserving the cortical functions subserved by that tissue. We report on the speech and language outcome of 14 children who underwent multiple subpial transection for treatment of Landau-Kleffner syndrome. Eleven children demonstrated significant postoperative improvement on measures of receptive or expressive vocabulary. Results indicate that early diagnosis and treatment optimize outcome, and that gains in language function are most likely to be seen years, rather than months, after surgery. Since an appropriate control group was not available, and that the best predictor of postoperative improvements in language function was that of length of time since surgery, these data might best be used as a benchmark against other Landau-Kleffner syndrome outcome studies. We conclude that multiple subpial transection may be useful in allowing for a restoration of speech and language abilities in children diagnosed with Landau-Kleffner syndrome.  (+info)

Influence of platelet-activating factor on cerebral microcirculation in rats: part 2. Local application. (3/432)

BACKGROUND AND PURPOSE: Platelet-activating factor (PAF) is involved in the development of secondary brain damage after ischemic and traumatic brain injury. On the basis of data from studies in peripheral organs, we hypothesized that PAF-mediated effects after cerebral injury could be secondary to alterations in cerebral microcirculation. METHODS: Changes in cerebral microcirculation focusing on leukocyte-endothelium interactions were quantified with the use of a closed cranial window model in Sprague-Dawley rats (n=33) by means of intravital fluorescence microscopy. The brain surface was superfused with PAF in concentrations from 10(-3) (n=3) to 10(-12) mol/L (n=6) for 20 minutes (5 mL/h). RESULTS: PAF 10(-4) mol/L (n=4) increased the number of rolling and adherent leukocytes in venules from 9.7+/-0.4 to 19.7+/-2.3 cells/100 mm. min (P=NS versus control) and from 2.2+/-0.5 to 4.3+/-0.7 cells/100 mm. min (P<0.05 versus control), respectively. Lower concentrations did not elicit leukocyte-endothelium interactions. Vessel diameters remained unchanged except for a transient increase of arteriolar diameters during superfusion with PAF 10(-4) and 10(-6) mol/L (n=6). Although only a limited area of the brain surface was exposed to PAF, the mediator induced a significant dose-dependent transitory arterial hypotension and caused irreversible circulatory shock at the high concentration (PAF 10(-3) mol/L). Arterial hypotension after administration of PAF 10(-3) mol/L could be attenuated by the intravenous pretreatment with the PAF antagonist WEB 2170BS. CONCLUSIONS: PAF, when locally released after brain injury, can penetrate the blood-brain barrier and induce systemic effects, including arterial hypotension. Its role as a mediator in the development of secondary brain damage seems, at least in the initial phase, not to be associated with disturbances of cerebral microcirculation or activation of leukocytes.  (+info)

MR of CNS sarcoidosis: correlation of imaging features to clinical symptoms and response to treatment. (4/432)

BACKGROUND AND PURPOSE: Sarcoidosis is an idiopathic systemic granulomatous disease, recognized in a patient when clinical and radiologic findings are confirmed by histopathologic analysis. The objective was to identify a relationship between MR imaging and clinical findings in CNS sarcoidosis. METHODS: The clinical charts of 461 patients with biopsy-proved sarcoidosis were reviewed retrospectively. Criteria for including patients in the study included those with symptoms referable to the CNS, excluding those with another explanation for their symptoms, those with headaches or other subjective complaints without accompanying objective findings, and those with peripheral neuropathy other than cranial nerve involvement or myopathy without CNS manifestations. Thirty-four of 38 patients whose conditions met the criteria for CNS sarcoidosis underwent a total of 82 MR examinations. The positive imaging findings were divided into categories as follows: pachymeningeal, leptomeningeal, nonenhancing brain parenchymal, enhancing brain parenchymal, cranial nerve, and spinal cord and nerve root involvement. Treatment response, clinical symptomatology, and any available histopathologic studies were analyzed with respect to imaging manifestations in each of the categories. RESULTS: Eighty-two percent of the patients with sarcoidosis with neurologic symptoms referable to the CNS had findings revealed by MR imaging. However, eight (40%) of 20 cranial nerve deficits seen at clinical examination of 13 patients were not seen at contrast-enhanced MR imaging, and 50% of the patients with symptoms referable to the pituitary axis had no abnormal findings on routine contrast-enhanced MR images. In contradistinction, 44% of 18 cranial nerves in nine patients with MR evidence of involvement had no symptoms referable to the involved cranial nerve. Clinical and radiologic deterioration occurred more commonly with leptomeningeal and enhancing brain parenchymal lesions. CONCLUSION: MR imaging can be used to confirm clinical suspicion and to show subclinical disease and the response of pathologic lesions to treatment.  (+info)

VEGF increases permeability of the blood-brain barrier via a nitric oxide synthase/cGMP-dependent pathway. (5/432)

It appears that the expression of vascular endothelial growth factor (VEGF) is increased during brain injury and thus may contribute to disruption of the blood-brain barrier (BBB) during cerebrovascular trauma. The first goal of this study was to determine the effect of VEGF on permeability of the BBB in vivo. The second goal was to determine possible cellular mechanisms by which VEGF increases permeability of the BBB. We examined the pial microcirculation in rats using intravital fluorescence microscopy. Permeability of the BBB [clearance of FITC-labeled dextran of molecular mass 10,000 Da (FITC-dextran-10K)] and diameter of pial arterioles were measured in absence and presence of VEGF (0.01 and 0.1 nM). During superfusion with vehicle (saline), clearance of FITC-dextran-10K from pial vessels was minimal and diameter of pial arterioles remained constant. Topical application of VEGF (0.01 nM) did not alter permeability of the BBB to FITC-dextran-10K or arteriolar diameter. However, superfusion with VEGF (0.1 nM) produced a marked increase in clearance of FITC-dextran-10K and a modest dilatation of pial arterioles. To determine a potential role for nitric oxide and stimulation of soluble guanylate cyclase in VEGF-induced increases in permeability of the BBB and arteriolar dilatation, we examined the effects of NG-monomethyl-L-arginine (L-NMMA; 10 microM) and 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ; 1.0 microM), respectively. L-NMMA and ODQ inhibited VEGF-induced increases in permeability of the BBB and arteriolar dilatation. The findings of the present study suggest that VEGF, which appears to be increased in brain tissue during cerebrovascular trauma, increases the permeability of the BBB via the synthesis/release of nitric oxide and subsequent activation of soluble guanylate cyclase.  (+info)

Carbon monoxide and cerebral microvascular tone in newborn pigs. (6/432)

The present study addresses the hypothesis that CO produced from endogenous heme oxygenase (HO) can dilate newborn cerebral arterioles. HO-2 protein was highly expressed in large and small blood vessels, as well as parenchyma, of newborn pig cerebrum. Topically applied CO dose-dependently dilated piglet pial arterioles in vivo over the range 10(-11)-10(-9) M (maximal response). CO-induced cerebrovascular dilation was abolished by treatment with the Ca2+-activated K+ channel inhibitors tetraethylammonium chloride and iberiotoxin. The HO substrate heme-L-lysinate also produced tetraethylammonium-inhibitable, dose-dependent dilation from 5 x 10(-8) to 5 x 10(-7) M (maximal). The HO inhibitor chromium mesoporphyrin blocked dilation of pial arterioles in response to heme-L-lysinate. In addition to inhibiting dilation to heme-L-lysinate, chromium mesoporphyrin also blocked pial arteriolar dilations in response to hypoxia but did not alter responses to hypercapnia or isoproterenol. We conclude that CO dilates pial arterioles via activation of Ca2+-activated K+ channels and that endogenous HO-2 potentially can produce sufficient CO to produce the dilation.  (+info)

Tortuous, engorged pial veins in intracranial dural arteriovenous fistulas: correlations with presentation, location, and MR findings in 122 patients. (7/432)

BACKGROUND AND PURPOSE: Tortuous, engorged veins can be identified on the venous phase of the brain circulation in patients with venous congestion related to an intracranial dural arteriovenous fistula (DAVF). The term pseudophlebitic pattern (PPP) has been used to describe this finding. The purpose of this study was to determine the prevalence of PPP in patients with intracranial DAVF and to analyze the relationship of this sign to presentation, location of the fistula, presence of retrograde leptomeningeal venous drainage, and MR findings. METHODS: We retrospectively reviewed the charts and imaging findings of 130 patients with intracranial DAVF. In 122 patients the venous phase of the brain circulation was adequately assessed. The PPP was graded as mild, moderate, or severe. RESULTS: PPP was found in 51 patients (42%). Thirty-two (73%) of the 44 patients who had a hemorrhage, neurologic deficit, or seizure had PPP as compared with 16 (21%) of the 75 who had a bruit or orbital signs. The three patients with either congestive heart failure or increasing head circumference had PPP. Fourteen (88%) of the 16 who had fistula of the superior sagittal sinus, straight sinus, or superior petrosal sinus had PPP. PPP was seen in 46 (81%) of 57 patients who had retrograde leptomeningeal venous drainage and in five (8%) of the 65 who had only sinosal drainage. Fourteen (88%) of the 16 who had white matter T2 hyperintensity on MR images had severe PPP. CONCLUSION: The PPP reflects venous congestion and is associated with an aggressive presentation with or without retrograde leptomeningeal venous drainage. PPP may be a useful prognostic indicator and should be considered in treatment decisions.  (+info)

Effects of melatonin on rat pial arteriolar diameter in vivo. (8/432)

1. Based on our finding that melatonin decreased the lower limit of cerebral blood flow autoregulation in rat, we previously suggested that melatonin constricts cerebral arterioles. The goal of this study was to demonstrate this vasoconstrictor action and investigate the mechanisms involved. 2. The effects of cumulative doses of melatonin (10-10 to 10-6 M) were examined in cerebral arterioles (30 - 50 microM) of male Wistar rats using an open skull preparation. Cerebral arterioles were exposed to two doses of melatonin (3x10-9 and 3x10-8 M) in the absence and presence of the mt1 and/or MT2 receptor antagonist, luzindole (2x10-6 M) and the Ca2+-activated K+ (BKCa) channel blocker, tetraethylammonium (TEA+, 10(-4) M). The effect of L-nitro arginine methyl ester (L-NAME, 10-8 M) was examined on arterioles after TEA+ superfusion. Cerebral arterioles were also exposed to the BKCa activator, NS1619 (10(-5) M), and to sodium nitroprusside (SNP, 10-8 M) in the absence and presence of melatonin (3x10-8 M). 3. Melatonin induced a dose-dependent constriction with an EC50 of 3.0+/-0.1 nM and a maximal constriction of -15+/(-1%). Luzindole abolished melatonin-induced vasoconstriction. TEA+ induced significant vasoconstriction (-10+/(-2%). No additional vasoconstriction was observed when melatonin was added to the aCSF in presence of TEA+, whereas L-NAME still induced vasoconstriction (-10+/(-1%). NS1619 induced vasodilatation (+11+/(-1%) which was 50% less in presence of melatonin. Vasodilatation induced by SNP (+12+/(-2%) was not diminished by melatonin. 4. Melatonin directly constricts small diameter cerebral arterioles in rats. This vasoconstrictor effect is mediated by inhibition of BKCa channels following activation of mt1 and/or MT2 receptors.  (+info)

We have reported for the first time some characteristics of the membrane potential of SMCs of human pial arteries. The main finding of this study was that in these vessels rhythmic contractions were associated with generation of APs during spontaneous or K+-induced depolarization. The resting membrane potential of human pial arteries in vitro varied between −40 and −70 mV. The membrane potential of SMCs in rhythmically constricting arteries was significantly less negative than that of the silent ones. This finding indicates that spontaneous activity may be the result of a depolarized state of SMCs. The incidence of spontaneous activity was higher in those arteries that were obtained from patients ,40 years old. Therefore, we cannot exclude an influence of age-related vascular changes or of disease on the determined properties of human pial arteries. Periodic spontaneous activity has been demonstrated in human coronary arteries22 23 24 and was most frequent in vessels taken from older ...
The major findings in newborn pigs are: (1) treatment with the astrocyte toxin, L-2αAAA, or the HO inhibitor, CrMP, block pial arteriolar dilation to ADP, but not to isoproterenol, bradykinin, or sodium nitroprusside; (2) ADP increases brain CO production and this increase is blocked by the astrocyte toxin or inhibition of HO; and (3) ADP increases CO production by astrocytes and, to a lesser extent, cerebral microvessels. These data, coupled with previous results showing CO dilates pial arterioles in vivo, suggest CO is an astrocyte-derived mediator of ADP-induced pial arteriolar dilation in piglets.. ADP can produce endothelium-dependent cerebral vasodilation,19 which may be mediated in part by NO and endothelium-derived hyperpolarizing factor in adult rats.20,21,30 In endothelium-denuded control arteries from rat brain, ADP also produced dose-dependent relaxation, but this relaxation was lower than that found in intact control arteries.31 In adult rats, ADP-induced pial arteriolar dilation ...
Both the blood brain barrier and the blood CSF barrier tightly regulate the CNS fluid interstitial fluid environment of the CNS. You, however, are talking about a different barrier, the barrier formed by the pia mater, sometimes called the brain/CSF barrier. This barrier is less well studied. It does appear to prevent transport of particulate matter and red blood cells, but allow the passage of immune cells and small molecules. In addition to your professors statement that the composition of CSF and brain interstitial fluid is similar, intrathecal injection directly into the CSF in the subarachnoid space provides an effective way to deliver drugs with CNS action, suggesting the pia mater does not effectively restrict small molecules (see Goodman and Gilmans The Pharmacological Basis of Therapeutics Ch 2).. ...
TY - JOUR. T1 - Interaction between ATP-sensitive K+ channels and nitric oxide on pial arterioles in piglets. AU - Bari, F.. AU - Errico, Robert A.. AU - Louis, Thomas M.. AU - Busija, David W.. PY - 1996. Y1 - 1996. N2 - The interaction between ATP-sensitive K+ channels (K(ATP)) and nitric oxide (NO) was studied in pial arterioles of piglets. We examined the effects of N(ω)-nitro-L-arginine methyl ester (L-NAME), a general inhibitor of nitric oxide synthase (NOS), and 7-nitroindazole (7-NI), a selective inhibitor of neuronal NOS, on aprikalim-induced cerebral vasodilation. Topically applied, aprikalim, a selective activator of K(ATP), dilated arterioles by 11 ± 7% at 10-8 M and 17 ± 6% at 10-6 M. After L-NAME treatment (15 mg/kg, i.v.), the response was reduced (4 ± 4% and 12 ± 7%, respectively; n = 8, p ,0.05). Administration of 7-NI (50 mg/kg, i.p.) did not change pial arteriolar responsiveness to aprikalim. However, both L-NAME and 7-NI reduced the vasodilator responses to 10-4 M ...

There can be little doubt that the vessel of the histological study drained blood from the retina directly to the pia mater. Material was not available to trace the further course of the retinopial vein. Its size, although small compared with the central retinal vein, was large enough to have drained a substantial area of the temporal retina. There is some doubt as to whether the retina was free of pathology, even though none was reported, as deep cupping of a small area of the disc was present. However, the possibility that the retinopial vein represented a pathological development is unlikely. Where development of supplementary venous drainage from the eye at the disc has been reported, drainage is to the choroid via optociliary veins, not to the optic nerve, and is regarded as a response to obstruction of venous blood flow from the retina.3-5 Moreover, it is associated with a lengthy history of blindness.. A recently reported superior hemiretinal retinal vein that appeared ophthalmoscopically ...
The apparatus was transferred to an inverted microscope (Nikon TMS-F, 20× objective, Nikon, Melville, NY). Steady-state measurements of internal diameter at the midpoint of the segment were made using a high resolution CCD video camera (Hitachi KPC503, Hitachi, San Jose, CA) and a video caliper (Living Systems) calibrated using a stage micrometer. The vessel was superfused with PSS at a rate of 6 ml/min, and the chamber was maintained at 37°C. Chamber temperature and pH were monitored continuously using a probe (Oakton, series 35616, Singapore), and samples of the superfusing buffer were periodically drawn from the chamber for gas analysis (AVL Instruments, model 995, Graz, Austria). A plexiglas cover excluded ambient air from the chamber. The reservoir containing the perfusate and superfusate and the vessel chamber itself were bubbled with gas whose composition was adjusted, using separate tanks and regulators for each of oxygen, carbon dioxide, and nitrogen, to achieve Po2and Pco2values in ...

The glia limitans, or the glial limiting membrane, is a thin barrier of astrocyte foot processes associated with the parenchymal basal lamina surrounding the brain and spinal cord. It is the outermost layer of neural tissue, and among its responsibilities is the prevention of the over migration of neurons and neuroglia, the supporting cells of the nervous system, into the meninges. The glia limitans also plays an important role in regulating the movement of small molecules and cells into the brain parenchyma by working in concert with other components of the central nervous system (CNS) such as the blood-brain barrier (BBB). The end foot processes extending from both perivascular and marginal astrocytes form a close association with the basal lamina of the parenchyma, or the functional components of the brain, to create the glia limitans. This membrane lies deep to the pia mater and the subpial space and surrounds the perivascular (Virchow-Robin) spaces. Any substance entering the central ...

Intriguing questions have recently been raised regarding the applicability of direct observations of the pial microcirculation to the behavior of the total cerebral microcirculation. Operating under the assumption that arteriolar tone and, thus, cerebrovascular resistance is, to some extent, directly related to the intrinsic energy metabolism of the arteriolar wall, a comparative histochemical analysis of cerebral microvessels, both pial and parenchymal, was undertaken. Reactions were chosen on the bases of representation of substrate and of enzymes of glycolysis, the hexose monophosphate shunt, beta-oxidation of fat, Krebs cycle, cytochrome system and ATP hydrolysis. Three metabolically distinct segments of the cerebral microvasculature were delineated with the pial vessels showing strong capacities for glycolysis, beta-oxidation of fats and utilization of glucose through the hexose monophosphate shunt. Microvessels of the gray matter have a qualitatively similar metabolic profile but the ...

The effects of systemic human recombinant interleukin 2 (rIL-2) infusion upon both the vasoconstrictor effect of hypocapnia and the endothelium-dependent vasodilator effect of acetylcholine (Ach) were examined in anesthetized rats equipped with cranial windows. Prior to the functional studies, each of six animals received an i.v. infusion of rIL-2 (6 × 105 IU/kg) every 8 h for 3 days. At the same time, six control animals received infusions of equivalent volumes of sterile water. Eight h after the final infusion, each animal was anesthetized and equipped with a cranial window for the observation of pial arterioles overlying the left frontoparietal cortex. Pial arteriolar diameters were measured before and after the topical application of Ach which in normal cerebral arterioles elicits the release of endothelium-dependent relaxing factor, causing vasodilation. When arteriolar diameters returned to base line, they were measured again both before and during hyperventilation-induced hypocapnia. ...
Series Editor: Arthur T. Skarin, MD, FACP, FCCP Systemic cancer can affect the central nervous system in several different ways, including direct tumor metastasis and indirect remote effects. Intracranial metastasis can involve the skull, dura, and leptomeninges (arachnoid and pia mater), as well as the brain parenchyma. Of these, parenchymal brain metastases are the most common and have been found in as many as 24% of cancer patients in autopsy studies. It has been reported that metastatic brain tumors outnumber primary brain tumors 10 to 1. To read the full article in PDF: Click here ...

Autopsy brain samples from 51 controls and 57 patients who died with encephalopathy of unknown origin were tested for HHV-6 & HHV-7 using immunohistochemistry, nested and real time PCR. Patients with encephalopathy had a greater frequency of HHV-6 & 7 (89.4%) compared to controls (68.6%).. Also, HHV-6 DNA was found at high levels in both the temporal and frontal lobes, and it was found significantly more frequently in the frontal lobe in these patients than in the temporal lobe.. Patients with encephalopathy also had a significantly higher viral load in the olfactory tract as well as the pia mater, the loose vascular coat that encloses the surface of the cerebral cortex. The authors suggest that the viral load may be high in these locations because these tissues may be used as a pathway to enter the CNS.. There was no difference in HHV-6B viral load in the hippocampus between the patients and controls. Only HHV-6B DNA was found; no HHV-6A DNA could be detected.. Read the full paper.. ...

The human brain is a soft, spongy collection of tissues and nerve cells. The main thing that protects the human brain is the bone of the skull encasing it. Then, there are three layers of membrane, called meninges that also aid in covering and protecting the brain. The three layers are the dura mater, arachnoid mater, and pia mater. The dura mater is closest to the bone, the arachnoid is in the middle and loosely surrounds the brain, and the pia mater is closest to the brain and attached to the spinal cord surface. Finally, the cerebrospinal fluid, a clear body fluid, also cushions the brain. ...
The outermost layer of the meninges and therefore closet to the skull is the Dura mater; it is a thick and tough layer composed of dense fibrous tissue which wraps almost entirely around the whole brain and spinal cord. There is little space between the Dura mater layer and the layer below/the bone above it, the exception to this is when (not in the meninges of the spinal cord) the Dura mater splits into two layers forming a gap between them, which is known as the venous sinus. The Dura contains larger blood vessels which split into the capillaries in the pia mater.. In the cranium, the Dura mater also acts as another layer of periosteum, however in the spine there is an epidural space (filled with fat) which separates the Dura mater and periosteum.. ...
The goal of this study was to determine whether responses of cerebral vessels to intravascular administration of serotonin are altered in stroke-prone spontaneously hypertensive rats. We measured pressure in pial arterioles and cerebral blood flow in normotensive and hypertensive rats during intra-atrial infusion of serotonin. In normotensive rats, pial arteriolar pressure was 48 +/- 3 mm Hg (mean +/- SEM) and cerebral blood flow was 48 +/- 5 ml/min/100 g under control conditions. Intra-atrial infusion of serotonin (5 and 50 micrograms/kg/min for 5 minutes) produced only minimal changes in pial arteriolar pressure (-3 +/- 4 and -4 +/- 4 mm Hg, respectively) and did not alter cerebral blood flow. In hypertensive rats, pial arteriolar pressure was 95 +/- 9 mm Hg and cerebral blood flow was 57 +/- 4 ml/min/100 g under control conditions. In contrast to normotensive rats, intra-atrial infusion of serotonin (5 and 50 micrograms/kg/min for 5 minutes) in hypertensive rats profoundly decreased pial ...
The blood supply of the meninges generally concerns the blood supply of the outer layer of dura mater rather than the inner layer of dura mater, arachnoid or pia mater which do not require a large blood supply. There are several arteries that sup...
BM is usually blood-borne, and most often associated with a systemic infection. From the clinical standpoint, it is important to confirm or exclude sepsis since it substantially compromises the patients prognosis. Initially bacteria accumulate in the lumen of choroid plexus capillaries located in the cerebral ventricles and in the small and medium-sized vessels of the subarachnoid space, where they induce an inflammatory response. Developing vasculitis leads to the inflammation of the arachnoid, dura mater and pia mater.. As a result of disruption to the blood-brain barrier, bacteria and inflammatory mediators (acute-phase proteins, leukotrienes, prostaglandins, among others) penetrate to the cerebrospinal fluid (CSF), thus exacerbating inflammation. In the acute phase cerebral vessels become dilated with increasing blood flow due to the influence of bacterial toxins. In later phases blood flow is reduced, which is associated with impaired vascular autoregulation(4). The cytotoxic activity of ...
For this reason, I use a lot of CranioSacral Therapy and Myofascial Release in my work. CranioSacral Therapy is a gentle and non-invasive modality. The CranioSacral system extends from the occiput (in the area of the poll), down the spine to the coccyx (tailbone) and is comprised of three layers of membranes. The outermost layer is the dura mater which is a tough, waterproof membrane that houses the brain and spinal cord. The next layer is the arachnoid layer, and the inner layer is the pia mater which adheres snugly to the inside of the spinal cord. These membranes are constantly bathed in fluid. This fluid is known as the cerebrospinal fluid. It pulses throughout the life of the horse (also all other animals as well as humans) and influences the movement of the skull bones and the connective tissue (fascia). ...
Subarachnoid hemorrhage (SAH) is bleeding into the subarachnoid space-the area between the arachnoid membrane and the pia mater surrounding the brain. Symptoms may include a severe headache of rapid onset, vomiting, decreased level of consciousness, fever, and sometimes seizures. Neck stiffness or neck pain are also relatively common. In about a quarter of people a small bleed with resolving symptoms occurs within a month of a larger bleed. SAH may occur as a result of a head injury or spontaneously, usually from a ruptured cerebral aneurysm. Risk factors for spontaneous cases included high blood pressure, smoking, family history, alcoholism, and cocaine use. Generally, the diagnosis can be determined by a CT scan of the head if done within six hours of symptom onset. Occasionally a lumbar puncture is also required. After confirmation further tests are usually performed to determine the underlying cause. Treatment is by prompt neurosurgery or radiologically guided interventions. Medications such ...

  • The pia, unlike the arachnoid, extends into the sulci in gyrencephalic animals. (bioontology.org)
  • The lower part, or filum terminale externum , closely adheres to the dura mater. (wikipedia.org)
  • At the retina, the maximum width was 68 μm and the vessel showed little change in width in its course through the nerve apart from slight reductions at each turn, until widening slightly to a maximum of 84 μm at the pia mater where it received two small pial veins. (bmj.com)
  • Dura mater is also the home to meningeal veins. (healthline.com)
  • Pia and Arachnoid are collectively called the Leptomeninx, and they are derived from the Neural Crest. (merlot.org)
  • Located between the pia and the ventricular zone, it contains the earliest born neurons and represents the beginning of corticogenesis prior to the emergence of the cortical plate. (biologists.org)
  • These arteries split into the capillaries in the pia mater. (wikipedia.org)
  • The purpose of this report is to morphometrically compare the optic nerve laminar and pia mater structure between humans and dogs, and to use previously reported tissue pressure measurements in the dog optic nerve to estimate individual-specific human optic nerve pressures and pressure gradients. (nih.gov)
  • Using previous measurements of optic nerve pressures and pressure gradients in dogs we estimate that at an IOP of 15 mmHg and a CSF pressure of 0 mmHg the mean pressure difference across the human pia mater will be 4.8 +/- 2.2 mmHg. (nih.gov)
  • Both the pia and arachnoid mater are derivatives of the neural crest while the dura is derived from embryonic mesoderm . (wikipedia.org)
  • During the dissection it was decided to render a running commentary on the Pia mater and a few of its gross, microscopic characteristics and its derivatives. (merlot.org)
