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...

By implanting a Teflon chamber subcutaneously into a sheep a mild aseptic inflammatory lesion was produced from which wound fluid could be sampled daily. The prostaglandin content of this wound fluid was examined. Prostaglandin E2 activity was found in all samples, and a peak was apparent on the fourth or fifth day after producing the lesion. The amount of prostaglandin activity appeared to be ...

Methods The concentrations of SP-A, SP-D, CRP, IgA, IgM, IgG, and rheumatoid factor were measured in the synovial fluid of 7 patients with rheumatoid arthritis and 3 samples of healthy synovial fluid obtained at autopsy. The bands obtained by specific antibodies in Western blotting to determine the surfactant protein concentration were analyzed densitometrically and synovial fluid total phospho...

for normally hydrated individuals. However, when working in stressful environments for extended durations, particularly when wearing personal protective equipment, fluid losses via sweat secretion are dramatically elevated, and can approach 8-16 L.day -1 . Indeed, during a moderate exercise-heat stress, whole-body sweat rates typically range between 1-1.5 L.h -1 , and fluid loss at this rate si...

BACKGROUND Diagnosis of ventilator associated pneumonia can be made by quantitative cultures of bronchoalveolar lavage fluid or of protected specimen brushings, though cultures require 24-48 hours to provide results. In 80% of cases aerobic Gram negative bacteria are the cause. METHODS A rapid diagnostic method of assessing the endotoxin content of lavage fluid by Limulus assay is described. ...

the use of flow cytometry in the clinical laboratory has grown substantially in the past decade. flow cytometric analysis provides a rapid qualitative and quantitative description of multiple characteristics of individual cells. for example, it is possible to detect the cell size and granularity, aspects of dna and rna content and the presence of cell surface and nuclear markers which are used ...

Sperm of the three-spined stickleback Gasterosteus aculeatus display a prolonged motility in the presence of ovarian fluid. The ovarian fluid prolongs sperm motility in freshwater from approximately 1 min to several hours, a trait that possibly gives the stickleback its unusual ability to spawn in waters of all salinities. The aim of the study was to look for factor(s) within the ovarian fluid ...

Perforated capsules were implanted aseptically into the brain parenchyma of dogs. The tissue and fluid formed within these intracerebral capsules (BC) were analysed for their ions and protein content. The results were compared with those for other perforated capsules implanted simultaneously into the subcutaneous tissue and muscle, respectively (denoted SC and MC). The following results were ob...

serum glucose levels (18±2 mg/dl, P <0.001) and serum insulin levels (12±3 IAU/ml, P < 0.001) in six chronically catheterized control fetuses of the same gestational ages. Glucose infusion to the fetuses did not alter maternal serum glucose (60±3 mg/dl) or serum insulin levels (35±5 MAU/ml). Arterial blood gases (pH 7.34±0.01, Po2 24.3±0.5 mmHg, Pco2 41.5±0.9 mmHg), oxygen saturation (73±2%), h...
