We describe a new technique of collecting sweat for measurement of osmolality and sodium concentrations. Eighty two subjects were studied--39 controls and 43 patients with cystic fibrosis. Adequate amounts of sweat were obtained in 81 subjects and sweat was analysed for both osmolality and sodium concentrations in 73 subjects. The 34 controls gave sweat osmolality and sodium values ranging from...
The high sweat electrolyte concentration in cystic fibrosis is most important in the diagnosis of this disease. The method used for its determination should be simple to perform, harmless to the patient, and accurate. The widely-used method of collecting sweat on a filter paper (Shwachman, Leubner, and Catzel, 1955) after pilocarpine iontophoresis (Gibson and Cooke, 1959) fulfils the first two ...
introduction: poroscopy is a method of identification in which the characteristics of sweat pores are compared from different aspects. these pore openings are present along the friction ridges found on the distal end of digits, palms and soles in the hands and feet. materials amd methods: this study enrolled 100 iranian males from the fars family who resided in khorasan razavi province. the ave...
BACKGROUND Understanding methamphetamine (MAMP) and amphetamine (AMP) excretion in sweat is important for interpreting sweat and hair testing results in judicial, workplace, and drug treatment settings. METHODS Participants (n = 8) received 4 10-mg (low) oral doses of sustained-release S-(+)-MAMP HCl (d-MAMP HCl) within 1 week in a double-blind, institutional review board-approved study. Five...
The responses of Anopheles gambiae Giles sensu stricto (Diptera: Culicidae) to odors from male and female axillary sweat incubated with human axilla bacteria were recorded in a dual-choice olfactometer. Staphylococcus epidermidis was selected for its low odor-producing pattern, Corynebacterium jeikeium for its strong Nα-acylglutamine aminoacylase activity liberating carboxylic acids including (...
BACKGROUND A challenging problem arising from cystic fibrosis (CF) newborn screening is the significant number of infants with hypertrypsinaemia (HIRT) with sweat chloride levels in the intermediate range and only one or no identified CF-causing mutations. OBJECTIVES To investigate the diagnostic value for CF of assessing CF transmembrane conductance regulator (CFTR) protein function by measu...
BACKGROUND For nearly 50 years the diagnosis of cystic fibrosis (CF) has depended on measurements of sweat chloride concentration. While the validity of this test is universally accepted, increasing diagnostic challenges and the search for adequate biomarker assays to support curative-orientated clinical drug trials have created a new demand for accurate, reliable and more practical CF tests. A...
Conflicting reports exist about the role of baroreflexes in efferent control of eccrine sweat rate. These conflicting reports may be due to differing mean body temperatures between studies. The purpose of this project was to test the hypothesis that mean body temperature modulates the effect of head-up tilt on sweat rate and skin sympathetic nerve activity (SSNA). To address this question, mean...
