Comment: Urinary excretion
of sodium and potassium are fairly reliable indicators of dietary intake of these electrolytes.
We know that the excretion
rate of inorganic trace minerals is between 85 percent and up to more than 99 percent.
The largest segment of the study population, 46%, had a sodium excretion
of 3-5 g/day, and the next largest segment, 44%, had a sodium excretion
of more than 5 g/day.
Results indicated that urinary magnesium excretion
was inversely correlated with age, systolic BP and triglyceride and CRP concentrations whilst being positively correlated with HDL cholesterol and urinary excretion
of calcium, sodium, potassium, albumin and creatinine.
In addition, the urinary excretion
of gamma-tocopherol and tocotrienol metabolites was not affected by dietary alpha-tocopherol.
It is logical that random urine samples collected later in the day would have higher values than first-void samples, because urinary excretion
of albumin usually is higher during the day.
Nitrogen losses are therefore inevitable, but nutrition can play an integral role in reducing excretion
as N excretion
is directly related to N intake.
Several possible physiological mechanisms have been suggested; for example, LMW proteins and Cd-bound metallothionein may have similar affinity for renal tubular binding sites, and excretion
of both proteins and U-Cd may be influenced by normal variation in diuresis (i.
Haslam believes that the taboo surrounding excretion
is partially learned.
This research was carried out to use excretion
of purine derivatives (PD) namely allantoin and uric acid as a parameter to estimate the microbial protein synthesis in the rumen of native swamp buffaloes in north of Iran,
Without changes in lean body mass, 24-hour creatinine excretion
should be relatively constant for each patient.
The WHO defines iodine deficiency as mild when urinary iodine excretion
is 50 pg/L to 99 pg/L, moderate when urinary iodine excretion
is 20 pg/L to 49 pg/L, and severe as less than 20 pg/L to 49 pg/L.
Based on 38 sodium-excretion
studies, published between 1957 and 2003, sodium excretions
in the urine of subjects were found to be unchanged throughout the study years.
Increases in RSNA decrease urinary sodium and water excretion
by increasing renal tubular water and sodium reabsorption throughout the nephron, decrease renal blood flow (RBF) and glomerular filtration rate (GFR) by constricting the renal vasculature, and increase the activity of the renin-angiotensin system (RAS) (3,4).
The article includes, in its longitudinal direction, an excretion
portion which is placed opposite a wearer's liquid excretion
portion and a rear section which is placed more on the back side than the excretion
portion, wherein a leak preventive wall is disposed on opposite side portions in the longitudinal direction.
