Serum Vitamin A, total protein, serum electrophoresis, were determined in pediatric patients with urolithiasis (mostly bladder stones) and compared to that of normal healthy volunteers. The level of Vitamin A in healthy volunteers was found to be significantly (P<0.001) higher than that of patients with urolithiasis. The amount of total serum protein, how­ever, was not significantly different i...

Background: Recently, in approach to spinal pathologies, the whole spine should be considered as a biomechanicalunit. Studies have shown the great importance of sagittal and coronal balance and the relationship between the variousparts of spine together and pelvis. Former studies have shown a close relationship between spinopelvic parametersand sagittal balance. A complete und...

After a 500-mg dose of cefaclor, the mean peak plasma level was 12.4 mug/ml and after a 250-mg dose it was 5 mug/ml in normal volunteers. Food intake significantly reduced absorption. Probenecid prolonged plasma levels. Mean plasma half-life in normal volunteers was 0.8 h. Only about 50% of the dose was excreted in the urine within 4 h in normal volunteers. Plasma half-life in patients with ren...

Leukoaraiosis quantified by computerized densitometric measurements of reduced Hounsfield numbers was correlated with local cerebral blood flow on the same computed tomographic images of 35 patients with multi-infarct dementia and 16 age-matched elderly normal volunteers. The ratio for area of frontal leukoaraiosis to total area of parenchyma among the patients was significantly greater than th...

Animal experiments have suggested that salt-balance, prostaglandin synthesis, and renal function are important determinants of the nondiuretic vascular effects of furosemide. To investigate the influence of these factors in humans, we studied 10 normal volunteers and five anephric patients. The volunteers were studied on three occasions: when on a 10 mEq/day sodium diet, on a 250 mEq/day sodium...

INTRODUCTION Motor neuron damage and cortical spinal tract (CST) degeneration in amyotrophic lateral sclerosis (ALS) are difficult to visualise and quantify on conventional magnetic resonance imaging (MRI). CLINICAL PICTURE We studied 8 ALS patients and 12 normal volunteers using diffusion tensor imaging (DTI) and fibre tractography using fibre assignment by continuous tracking (FACT) to stud...

The Word Completion Memory Test (WCMT) was developed to detect sophisticated attempts at simulating memory impairment. The primary purpose of the present study was to provide additional validity and reliability information about the WCMT. Seventy-one participants were recruited for this study: 30 normal volunteers and 11 memory-disordered patients instructed to perform their best, and 30 normal...

Red cells, derived from 13 patients with iron-deficiency anaemia, were found to have a normal life span in the patients' own circulations and those of normal volunteers.
