Thirty unselected subjects with chronic obstructive pulmonary emphysema were studied. The diagnosis in each instance was substantiated by fluoroscopic observation and evaluation of pulmonary function. Each patient was studied in the fasting state. Intubation was carried out under fluoroscopic control and an indwelling arterial needle was inserted. Continuous gastric suction was applied until su...

A combination of narrow range isoelectric focusing, electrophoresis on polyacrylamide gel, and gel exclusion on Sephadex reveals the presence of at least 9, possibly 11 isoenzymes of phospholipase A in Naja naja (cobra) venom. Their isoelectric points range from pH 4.60 to 5.66 and their molecular weights from 8,500 to 20,200. The most abundant form (isoelectric point = pH 4.95) has been isolat...

CONTEXT The ingestion of gluten is responsible for the symptoms of Celiac disease, but other environmental factors can also influence. Strains of the Bifidobacterium genus have been shown to afford protection against the inflammatory response and mucosal damage caused by gliadin peptides in vitro. OBJECTIVES This study was designed to compare the concentration of fecal bifidobacteria and pH o...

A new method for determining chlorinity of water was developed in order to improve the old method by alleviating the environmental problems associated with the toxic chromate. The method utilizes a mediator, a weak acid that can form an insoluble salt with the titrant. The mediator triggers a sudden change in pH at an equivalence point in a titration. Thus, the equivalence point can be determin...

The aims of endodontic treatment in cases of apical periodontitis are to reduce as much as possible the number of microorganisms inside the root canal system and to inactivate toxins produced by them. Chlorhexidine has a wide spectrum of antimicrobial activity and is known for its property of substansivity. It is also known that dentin exerts a buffering effect under wide pH variations, and may...

PURPOSE The purpose of this study was to examine the effects of aroma massage on pruritus, skin pH, skin hydration and sleep in elders in long-term care hospitals. METHODS The participants were elders over 65 years old admitted to long-term care. They were assigned to the experimental group (26) or control group (28). Data were collected from May to August, 2012. Visual Analogue Scale and Ver...

STUDY OBJECTIVES Hypertonic saline solution inhalation is suspected to produce airway inflammation. DESIGN The aim of this study was to verify this hypothesis by measuring inflammatory markers in exhaled breath condensate (EBC) collected before and after sputum induction with hypertonic and isotonic saline solution. PATIENTS AND METHODS We enrolled 10 patients with asthma, 10 patients with ...

The liquors were found to be adulterated with impure water from different sources. The measurement of pH, chloride concentration, total dissolved solid, total suspended solid and heavy metals reveals the adulteration in liquors. The duplicate brands contain rectified spirit, caramel, coloring agents, flavoring agents and essential oils which are not according to specifications. The adulterated ...

Oxalate biosensors (OBs) are based on either measurement of oxygen or electrons generated from splitting of H 2 O 2 or heat released during oxidation of oxalate by immobilized oxalate oxidase. OBs are grouped in four classes based on probe used (DO meter, electrochemical, SIRE technology and thermochip). OBs work optimally at: time, 5 s to 15 min; pH, 2.8 8.0; temp., 30 38°C and linearity, 1.0 ...

This study aims to determine the effect of fermentation time on microbiological (total lactic acid bacteria), chemistry (pH, total titrated acid) and organoleptic (color, aroma, flavor) qualities product starfruit (Averrhoa carambola L.) probiotic juice drink cultured by L. plantarum B1765. B1765 had been studied has potency as probiotics candidate. The used is 0, 6, 18, 24 hours. Total bacteri...
