Methods An inflatable balloon was secured around the left coronary artery of Sprague Dawley rats. 5-7 days after surgery rats were placed in a Bruker Biospec 9.4T small animal MR system. To enhance bicarbonate signal, animals received an iv glucose/potassium infusion. The tubing of the occluder was connected to extension tubing to allow occlusion while the animal remained in the bore of the MR ...

OBJECTIVE To review and compare the 'metabolic' component of an acid-base abnormality by assessing the arterial blood bicarbonate and the 'strong ion difference'. DATA SOURCES A review of published peer-review articles and studies reported from 1983 to 1999 and identified through a MEDLINE search on 'strong ion difference'. SUMMARY OF REVIEW The Henderson-Hasselbalch equation describes the ...

BACKGROUND/AIMS Ultrafiltration that occurs during hemodialysis (HD) promotes profound alterations in a relatively short period of time. The dialysate content of bicarbonate (DBic) and potassium (DK) may have impact over intradialytic hemodynamics, which goes beyond ultrafiltration, and its impact was evaluated in a prospective cohort. METHODS 30 patients under HD were submitted to hemodynami...

Background: Electrolyte disorders are common in patients in the emergency department and have been associated with increased morbidity and mortality. In this respect sodium, potassium and calcium are the most important cations, whose improper adjustment may cause severe disorders in neuromuscular, gastrointestinal, respiratory and cardiovascular systems. Aims & Objectives: This study intends to...

Ternate Basin is located a small volcanic island in the archipelago of North Maluku, Indonesia. This has very limited water resources and prone to seawater intrusion. study aims determine analyze distribution hydrogeological interest points, patterns directions groundwater flow, hydrogeochemical quality facies. Determination free aquifer zone was carried out by geoelectric measurements 37 while...

-Normotensive salt sensitivity, a putative precursor of hypertension, might be quite frequent in African Americans (blacks) and less frequent in Caucasian Americans (whites), but only when dietary potassium is deficient and not when maintained well within the normal range. We tested this hypothesis in 41 metabolically controlled studies of 38 healthy normotensive men (24 blacks, 14 whites) who ...

Rod intracellular pH (pHi) in the intact frog retina was measured fluorometrically with the dye 2',7'-bis(2-carboxyethyl)-5(and-6)-carboxyfluorescein under treatments chosen to affect putative pH-regulating transport mechanisms in the plasma membrane. The purpose was to relate possible pHi changes to previously reported effects on photoresponses. In nominally bicarbonate-free Ringer, applicatio...
