Leukotriene (LT)B4 in exhaled breath condensate (EBC) has been reported to be elevated in airway inflammation. The origin of leukotrienes in EBC is, however, not established. The aims of this study are to measure LTB4 levels in EBC collected in two challenges characterised by a strong neutrophilic airway inflammation and to compare LTB4 levels in EBC with levels in sputum and saliva. LTB4 and a...

We have determined and compared trace metals concentration in saliva taken from chemical warfare injures who were under the exposure of mustard gas and healthy subjects by means of inductively coupled plasma optical emission spectroscopy (ICP-OES) for the first time. The influence of preliminary operations on the accuracy of ICP-OES analysis, blood contamination, the number of restored teeth in...

The aim of this study was to compare the content of nickel in the saliva and dental biofilm in young patients with and without orthodontic appliances. The possible influence of a dietary intake of nickel on recorded nickel levels was examined. Nickel content in unstimulated whole saliva and in dental plaque of 24 boys and girls (mean age 14.8 years) with intraoral fixed orthodontic appliances w...

The objectives of this experiment looked at were that the DNA, both skin cells and saliva, have potential binding with superglue as it coats each object being fumed. If DNA has superglue, then is very possible for to be carried in air by humidifier, thus contaminating other objects. For first experiment, two saliva covered microscope slides, one female male, fumed along 25 sterile slides. Each ...

The purpose of this in vitro study was to analyze and identify a methodology for the improvement shear bond strength orthodontic brackets bonded with two adhesive systems considered be widely used, Transbond Plus Color Change Self-Etching Primer Fuji Ortho LC orthophosphoric acid under various enamel conditions: dry, moistened water saliva. sample size included group 120 freshly extracted premo...

Since the first attempts to use standardised methods for sampling induced airways sputum, two methods for processing the expectorate have evolved. The first involves selecting all viscid or denser portions from the expectorated sample with the aid of an inverted microscope [1, 2]. This method has been extensively evaluated and reported in detail [2–4]. The second approach involves processing th...

background and objectives : bartonella species are being recognized as increasingly important bacterial pathogens in veterinary and human medicine. these organisms can be transmitted by an arthropod vector or alternatively by animal scratches or bites. the objectives of this study were to identify contamination of cat's saliva and nail with b. henselae as a causative role to infect human in a s...
