BACKGROUND The SUSPPUP ratio [(serum sodium/urinary sodium)/(serum potassium²/urinary potassium)] has been proposed as a marker to screen for primary aldosteronism (PA). The original study found an area under the receiver operating characteristic (ROC) curve of 0·90 to detect PA; the sensitivity was 89% and specificity 86% for a ratio over 5·3 L mmol⁻¹. MATERIALS AND METHODS Patients attendin...

) It is possible that in this case, TC had developed before QTc prolongation and attack of PVT because (i) QTc gradually shortened and attacks of PVT disappeared regardless of serum potassium level after admission, and (ii) the patient had gastrointestinal symptoms and was diagnosed with dehydration in a previous hospital 5 days before admission to our hospital, which was the most probable phys...

In this study 71 head of conceiving ewe and their progeny (91 head) from the flock of Lori-Bakhtiari sheep (360 head), in Sholi Station were randomly selected to determine the relationship between the immunoglobulin (IgG) concentration in the ewe's serum and colostrum, and lamb's serum. Ewe blood sample, colostrum of ewe and blood of the lamb was taken 2 weeks before parturition, 1 to 8 hours a...

the most accepted method of secondary prophylaxis in rheumatic fever (rf) has been an injection of 1,200,000 units of benzathine penicillin g (bpg) every 4 weeks, but recurrences have been reported in some patients despite such a prophylaxis program. the who recommended bpg injections every 3 weeks in high risk patients and situations due to some published data in favor of inadequacy of once ev...

This study was conducted to determine the effect of sex and age on serum biochemistry parameters of turkeys (Meleagris gallopavo ). Forty healthy turkeys of three different age groups (4-8weeks old, 12-20weeks old and adults) were used. Statistical comparisons were made for differences in values between male and females and among different ages. Female turkeys had significantly (p<0.05) higher ...

THE ease and rapidity with which the whole pituitary or part of the gland can be removed in Xenopus laevis, the low post-operative mortality and the fact that the animals survive the operation for more than two years, suggested an investigation into the relation between the pituitary and several metabolic variables. In a previous paper (Shapiro and Zwarenstein, 1933) the effect of hypophysectom...

Reducing the actions of the renin-angiotensin-aldosterone system with angiotensin-converting enzyme inhibitors (ACE inhibitors) and angiotensin receptor blockers (ARBs) slows nephropathy progression in patients with or without diabetes. These drug classes have proven therapeutic benefits, particularly in patients with renal insufficiency (ie, serum creatinine level 133-265 micromol/L [1.5-3.0 m...

Introduction: The aim of this study was to evaluate the effect of distilled water as an irrigation fluid for percutaneous nephrolithotomy (PCNL) on the serum concentrations of sodium. Materials and Methods: A total of 30 patients with kidney calculi underwent tubeless PCNL using distilled water as the irrigation fluid. During the procedure, intravenous Ringer lactate solution was used if necess...

AIMS Potassium homeostasis is essential for normal myocardial function, and low serum potassium may cause fatal arrhythmias. However, the association of low potassium and long-term mortality and morbidity in heart failure (HF) is largely unknown. METHODS AND RESULTS We studied 6845 HF patients in the Digitalis Investigation Group trial with serum potassium levels < or =5.5 mEq/L. Of these, 11...
