Therapeutic control of human immunodeficiency virus type 1 (HIV-1) in peripheral compartments does not assure control in the central nervous system. Inadequate drug penetration may provide a sanctuary from which resistant virus can emerge or allow development of psychomotor abnormalities. To characterize the effect of ritonavir on indinavir disposition into cerebrospinal fluid, seven HIV-infect...

BACKGROUND AND PURPOSE In this study we investigated whether cerebrospinal fluid in patients with brain infarction possesses an activity that contributes to the evolution of brain ischemia. As a test, the effect of cerebrospinal fluid on Ca2+ influx into the intracellular space was chosen because this process is a mechanism for vasospasm, platelet aggregation as thrombi, and neuron damage. ME...

A total of 38 adult cases of aseptic meningitis were diagnosed based on clinical manifestations as well as examination of cerebrospinal fluid at Kaohsiung Veterans General Hospital in 2001. The majority (31 cases, 82%) of cases occurred between June and August, and most (33 cases, 87%) of them aged from 18 to 35 years (median age, 25 years). The male-to-female ratio was 2.16:1. Common clinical ...

Cerebrospinal fluid has shown itself to be an essential brain component during development. This is particularly evident at the earliest stages of development where a lot of research, performed mainly in chick embryos, supports the evidence that cerebrospinal fluid is involved in different mechanisms controlling brain growth and morphogenesis, by exerting a trophic effect on neuroepithelial pre...

The charts of 750 patients were reviewed to determine the value of routinely removing cerebrospinal fluid at the time of myelography and cisternography for chemical and cytologic examination. In most patients cerebrospinal fluid findings were normal. In the few abnormal studies, the findings were often uninformative, superfluous, or insufficient for appropriate diagnosis. In no instance did rou...

OBJECTIVE To study the application value of procalcitonin (PCT) in patients with central nervous system (CNS) infection. PATIENTS AND METHODS A total of 66 patients, including 24 patients with suppurative meningitis, 20 patients with viral meningitis and 22 patients with tuberculous meningitis, were enrolled. 20 patients admitted to the hospital due to epilepsy or headache without infection i...

BACKGROUND Serial cerebral angiograms, computed tomography, and magnetic resonance imaging are among the proposed methods for monitoring disease activity and response to therapy in isolated angiitis of the central nervous system. Cerebrospinal fluid has not proved to be useful in monitoring clinical course. CASE DESCRIPTION We describe a 45-year-old man with histological diagnosis of isolated...

AIM To evaluate ventriculo-cisternal perfusion as a method for measuring cerebrospinal fluid formation rate, calculated by means of the Heisey et al equation. Method. All experiments were carried out on anesthetized domestic cats fixed in the sphinx position in a stereotaxic frame. Ventriculo-cisternal perfusion was used at an intracranial pressure of -10 cm H2O at different perfusion rates (32...

The soluble fraction of brain samples from patients with Alzheimer's disease contains highly biologically active amyloid-β seeds. In this study, we sought to assess the potency of soluble amyloid-β seeds derived from the brain and cerebrospinal fluid. Soluble Alzheimer's disease brain extracts were serially diluted and then injected into the hippocampus of young, APP transgenic mice. Eight mont...

Human cerebrospinal fluid investigated byimmunoelectrophoresis with an antiserum against human cerebrospinal fluid has been shown to contain two proteins, which cannot be demonstrated in human serum (Clausen, 1961; MacPherson and Cosgrove, 1961; Hochwald and Thorbecke, 1962). These proteins will here be named fl-trace protein and y-trace protein according to Hochwald and Thorbecke (1962). Other...
