Introduction and purpose. The cerebrospinal fluid contains many biologically active substances, which have a broad influence on different points of application in the organism. We performed the research of the influence of cerebrospinal fluid on the rats lungs (in the connection with the studies, provided in our department and devoted to influence of xenogenic cerebrospinal fluid (XCSF) on the organism of rats). Materials and methods. The investigation was performed on 84 Wistar rats of both sexes, which were divided into the experimental and control groups. The experiment was performed on impuberal (group 1), puberal (group 2) and aged rats (group 3). The duration of the experiment was 7 (for the groups 1 and 2), 30 (for all groups) and 90 days (for the groups 2 and 3). The rats of the experimental group got XCSF at the dose 0.002 ml/g three times with the interval of 2 days (for 7-day experiment) or ten times (for 30- and 90-day experiments). The control group received 0.9 % NaCl using the ...
Recent advances in magnetic resonance imaging have made it possible to visualize and quantify flow of cerebrospinal fluid (CSF) in the brain. The net flow of CSF through the cerebral aqueduct was used to measure CSF production in six normal volunteers at different times during a 24-h period. CSF production varied greatly both intra- and interindividually. The average CSF production in each time interval showed a clear tendency to circadian variation, with a minimum production 30% of maximum values (12 +/- 7 ml/h) approximately 1800 h and a nightly peak production approximately 0200 h of 42 +/- 2 ml/h. The total CSF production during the whole 24-h period, calculated as an average of all measurements, was 650 ml for the whole group and 630 ml for repeated measurements in each time interval in one of the volunteers ...
Although there are many studies of the effect of epidural saline injection on reinforcement of spinal anesthesia in CSE, there is great variability in the results regarding the extent of epidural saline injection-induced spinal anesthesia because of methodologic differences among the studies, such as the use of local anesthetics for spinal anesthesia and the timing of the saline injection.2-9 Generalizing the results of these studies, the ability to increase dermatomal spread by increasing epidural volume seems to be time dependent.1-9 Beyond 20 min or after two-segment regression has begun, epidural top-up with saline does not affect sensory block extension.6,7 With regard to the increased sensory block level in CSE anesthesia, what are the implications of the saline injection-induced reduction in CSF volume in the current study? Previous studies indicated that there is a significant correlation between the lumbosacral CSF volume and sensory block spread of spinal anesthesia.10,11 Calculation ...
A Cerebral Spinal Meningitis outbreak has killed more than 156 people throughout Nigeria. Jigwa, Kano, Bauchi, Yobe, and Katsina states are currently among the worst hit. A graver report from UNICEF states that the death toll is much steeper with 9,086 cases and 562 deaths. Out of four West African countries in the midst of meningitis outbreaks (Nigeria, Niger, Burkina Faso, and Mali), Nigeria is currently reported to be the most affected. Due to Nigerias location, in sub-Saharan Africas "Meningitis Belt", seasonal epidemics expectedly occur in a cyclic pattern. Dry weather, dusty winds, cold nights, and large populations living in overcrowded conditions leave people vulnerable to respiratory infections and are among some of the reasons behind the Meningitis Belts high burden of meningococcal disease.. Cerebral Spinal Meningitis (CSM) is most often caused by the bacteria Neisseria meningitides. Bacterial meningitis is an infection of the meninges, the thin covering of the brain and spinal ...

The effect of graded change of the CSF amount on the clinical status, intracerebral pressure and brain bioelectrical activity was studied in 31 patients operated on for brain tumors of various sites. Normally, the graded change in the CSF amount made with an object of examining the biophysical characteristics of the intracranial system did not produce the impairment of the patients status. Discomfort sensation that occurred in rare cases was not a consequence of either hypo- or hypertension as such but of the absence of CNS ability to adapt rapidly to the changes of the pressure in the cranium. The graded change in the CSF amount and thus in the CSF pressure caused minimum transitory changes in the intracerebral pressure of interstitial liquid and in brain bioelectrical activity. The data obtained indicate the feasibility of studying the biophysic characteristics of the intracranial system by means of graded changes of the CSF amount in neurosurgical patients undergoing acute postoperative period.
Using rare tumor tissue specimens, researchers recently learned that an important protein that controls gene expression, known as histone H3, is mutated in up to 80% of diffuse midline gliomas. These mutations can occur in multiple genes encoding different histone protein isoforms (e.g. histone H3.3 and H3.1), and result in alteration in the amino acid sequence of the N-terminal tail of the affected histone protein (K27M and G34V). These H3 mutations also correlate with distinct tumor molecular characteristics, a more aggressive clinical course, and poorer response to conventional treatment. As a result, detection of a histone H3 mutation in brain tumor tissue through genetic sequencing or histopathologic staining is now considered diagnostic for this disease.. In contrast to midline glioma tumor tissue, cerebrospinal fluid (CSF) can be easily and safely collected in the clinic, and studied in the laboratory. I previously reported the detection of tumor-related proteins in CSF from patients with ...

An accurate and reproducible method for measuring the volume of the cranial CSF spaces was developed in the MRI unit in Glasgow by Dr. B. Condon in 1986. Using this MRI method the total cranial, cortical sulcal, ventricular and posterior fossa CSF volumes could be accurately measured, whereas only ventricular CSF volume could be estimated by previous techniques. The aim of this thesis was firstly to examine the technique critically and to reduce factors that might affect the accuracy or reproducibility of CSF volume measurement; secondly, to determine the normal range of CSF volume; thirdly, to study physiological factors that might influence the cranial CSF volume; and lastly to assess the research and clinical potential of these measurements in conditions where the CSF volumes might be altered. The original technique was modified. The accuracy of the method was improved by using 0.9% sodium chloride as a calibration reference solution, rather than water, as saline was found to produce a signal ...

Hello everyone, I had my 6 month CT scan yesterday with and without contrast, results today. I had a partial nephrectomy (3.9 x 2.5 cm, chromophobe grade 2) 6 months ago. The scan results indicate "small fluid density collection is noted with no residual enhancing mass, or evidence of metastatic disease.". My urologist requested an office visit in 6 months and another CT scan in 12 months. He said if I could have a CT scan in 6 months but did not recomend it. He was not concerned with the fluid. It was small, but Im unsure of actual size.. The fluid is in the area where they took the kidney wedge out. So, did I get good news, or not? I think I got good news but the fluid worries me. Does anyone have any experience with this? If so please comment.. Thanks a bunch in advace!!. BG ...
CSF analysis is an important diagnostic tool in the investigation of neurological patients, but there are limitations to it. The cell count and protein level of the CSF can be thought of as a CNS analogue of the CBC and serum protein level. Abnormalities in the colour, cellularity and protein level of the CSF are strongly indicative of neurological disease and often contribute to the diagnosis, but are non-specific and only occasionally provide a definitive diagnosis by themselves. CNS diseases also do not always cause alterations in the CSF - abnormalities depend on the location and extent of the lesion. Prior treatment with corticosteroids may interfere with CSF and reduce the white blood cell count and percentage of neutrophils. CSF should ideally be processed (or preserved) within 30 minutes after collection because the cells deteriorate rapidly due to little protein content.. CSF collection should be performed prior to myelography, since contrast agents may induce meningeal irritation and ...
The Cerebral Spinal Fluid helps to remove heavy metals and toxins across the blood brain barrier and distribute nutrients. When there is less flow of Cerebral Spinal Fluid there is more of a chance the toxins will become trapped and start to "clog up" the brain with plaque and deprive the brain of essential nutrients. This important cleansing or washing effect by the Cerebral Spinal Fluid helps to make sure that these harmful toxins do not accumulate and affect our brain tissue.Inflammation in the body that is the result of certain diseases such as arthritis, osteoporosis, diabetes, heart disease and others can accumulate and "overflow" across the blood brain barrier and also affect the brain. In many cases it was noted that patients with Alzheimer and Dementia had a previous history of at least one chronic disease processes. ...
14 months from EDI. NC functioning was measured by Global Deficit Score (GDS). HIV DNA levels were measured in peripheral blood mononuclear cells (PBMC) and CSF cells by droplet digital PCR; soluble inflammatory markers (sCD163, IL-6, MCP-1, TNF-α) and marker of neuronal damage (neurofilament chain [NFL]) were measured in blood plasma and CSF supernatant by immunoassays. Next generation sequencing (NGS) data by Roche 454 were successfully generated for HIV env from 8 paired blood and CSF cell pellets (3 with early and 5 with late ART). Viral compartmentalization analysis via Fst statistics was performed using NGS data and repeated using representative haplotypes to guard against possible skewing of allelic frequencies due to PCR amplification and other biases. Cross-sectional comparisons between groups (early versus later ART) were performed using non-parametric statistical analysis ...
Cerebrospinal fluid (CSF) analysis is commonly referred to as a spinal tap. During this procedure, a small volume of spinal fluid is collected and submitted to a laboratory for analysis of protein content, white blood cell count and determination of the types of white blood cells that are present. Spinal fluid is very sensitive for identifying disease in the central nervous system, but is not very specific to which disease is present as there is a great deal of overlap between diseases.. CSF analysis is used in conjunction with other tests, including MRI, to narrow the list of possible neurological diseases. In some cases, CSF will provide a definitive diagnosis, such as lymphoma, a type of cancer. Tests for several infectious diseases (Figure 2) can be performed on spinal fluid if needed.. In animals this procedure is performed under general anesthesia. While a person may be asked to lie still for a procedure, an animal cannot. However, since the animals are under anesthesia, there is no pain ...

In normal patients, blood and cerebrospinal fluid (CSF) contain circulating cells and other molecules such as proteins and nucleic acids. In patients with central nervous system (CNS) and other conditions, the levels of these molecules may be altered. In several other studies at our institution, the investigators are investigating such molecules in tumor specimens as well as the blood and cerebrospinal fluid of pediatric patients with CNS tumors. However, these levels are difficult to interpret without comparing them to levels in patients without CNS tumors. The investigators propose a study to collect small amounts of blood and cerebrospinal fluid from pediatric patients without CNS tumors who are undergoing a diagnostic or therapeutic neurosurgical procedure aimed at addressing altered CSF dynamics ...

A Matlab Simulink model was developed reproducing each vessel section by a distensible compartment. Therefore the cerebral vascular tree was divided into 13 sections from carotid artery to venous sinuses and the pulsatile carotid artery and sinus pressure were inputted as Fourier series. The cross sectional area was varied according to literature data and flow resistance was implemented taking into account the rheological characteristics of blood. The Windkessel function and relaxation properties of vascular walls were integrated by a Voigt model, enabling the variation of wall properties for each section individually. Due to the distensible vessel walls each section interacts with the CSF compartment and autoregulation was implemented by a simple proportional controller. After parameterisation mean pressure and pressure amplitude in the vessel sections showed good accordance with literature values [4]. ...

In the pelvis there is a large sepated cystic mass lesion seen occupying most of the pelvis and lower abdomen. This measures 14 x 9.3 x 11.1cm in size and demonstrates septation and predominantly fluid density. At its right posterolateral wall therte is also a slightly denser and minimal contrast enhancing mural nodule present. This measures approximately 17mm in size. I note the history of possible hydrosalpinx but I feel this lesion is too rounded and septated in appearance and likely represents a cystic tumour of the ovary ? right ovarian origin rather than hydrosalpinx. Suggest correlation with clinical history. I note there was a question raised previously with possible oophorectomy in the CT report in 2008. In understand the patient is to have a second gynaecological opinion tomorrow. ...

Values of Magnetic Resonance Imaging and Cerebrospinal fluid analysis in the diagnosis of Central NervousSystem associated infectious diseases
By means of radial immunodiffusion, immunoglobulins A, G, M and albumin were determined in serum and unconcentrated cerebrospinal fluid from 182 controls and 141 patients. Concentrations in cerebrospinal fluid and serum of patients did not correlate, not even in those groups whose elevated immunoglobulin and albumin concentrations in cerebrospinal fluid resulted from damage to the blood-cerebrospinal fluid barrier, as in inflammatory diseases and neoplastic processes of the central nervous system or of the meninges.--Concentrations of immunoglobulins in cerebrospinal fluid should therefore be evaluated independently of the serum concentrations. Cerebrospinal fluid and serum constitute samples from two separate compartments which are capable of independent immune reactions.

The objective of this work is to quantify age-related differences in the characteristics and coupling of cerebral arterial inflow and cerebrospinal fluid (CSF) dynamics. To this end, 3T phase-contrast magnetic resonance imaging blood and CSF flow data of eleven young (24 ± 3 years) and eleven elderly subjects (70 ± 5 years) with a comparable sex-ratio were acquired. Flow waveforms and their frequency composition, transfer functions from blood to CSF flows and cross-correlations were analyzed. The magnitudes of the frequency components of CSF flow in the aqueduct differ significantly between the two age groups, as do the frequency components of the cervical spinal CSF and the arterial flows. The males aqueductal CSF stroke volumes and average flow rates are significantly higher than those of the females. Transfer functions and cross-correlations between arterial blood and CSF flow reveal significant age-dependence of phase-shift between these, as do the waveforms of arterial blood, as well as ...
Clinical measurement of intracranial pressure (ICP) is often performed to aid diagnosis of hydrocephalus. This review discusses analysis of ICP and its components for the investigation of cerebrospinal fluid (CSF) dynamics. The role of pulse, slow and respiratory waveforms of ICP in diagnosis, prognostication and management of hydrocephalus is presented. Two methods related to ICP measurement are listed: an overnight monitoring of ICP and a constant-rate infusion study. Due to the dynamic nature of ICP, a snapshot manometric measurement of ICP is of limited use as it might lead to unreliable results. Therefore, monitoring of ICP over longer time combined with analysis of its waveforms provides more detailed information on the state of pressure-volume compensation. The infusion study implements ICP signal processing and CSF circulation model analysis in order to assess the cerebrospinal dynamics variables, such as CSF outflow resistance, compliance of CSF space, pressure amplitude, reference pressure,
