Cortisol and creatinine were measured in two consecutive overnight urine collections from 103 healthy school children, ages seven to 18.5 years. Mean cortisol and creatinine concentrations were respectively 194 nmol/L and 12.7 mmol/L. The data were statistically analyzed to simultaneously assess any effects of sex, age, weight, day of collection, and urine volume. Mean urine volume for boys exc...

The diuretic activity of methanol extract of Oxystelma esculentum aerial parts (MEOE) was studied in male Wister albino rats at 5h and 24h interval. The animals were divided into 5 groups: control, urea, furosemide and 200mg/kg and 400mg/kg MEOE. The extract was administered intraperitoneally (i.p) pretreated and all animals were saline MEOE. The urine volume (in mL) and electrolytes excretio...

To investigate age-associated impairments in fluid homeostasis, 4-mo (young) and 32-mo (old) Fischer 344/BN male rats were studied before and after a dietary sodium load. Transferring young rats from a low-sodium (LS) to a high-sodium (HS) diet increased water intake and urine volume by 1.9- and 3.0-fold, respectively, while urine osmolality and plasma aldosterone decreased by 33 and 98%. Conco...

background: tocotrienols (t3) were neglected in the past; today, get attentions due to their antioxidant and none‑antioxidant activity. the objective of this study was to evaluate the effects of the daily intake of 200 mg t3 added in canola oil over 8 weeks on microalbuminuria, inflammation, and nitrosative stress in type 2 diabetic patients. methods: this study was a double‑blinded, placebo‑co...

In previous papers (1, 2) it was shown that when the urine volume output falls below about 0.35 ml. per minute, the urine becomes " maximally" concentrated with respect to urea. The urea concentration of the urine is constant below this critical volume, and thus the urea clearance (U V/B) varies directly and quantitatively with the urine volume (V). In an effort to analyze the mechanism of rena...

rates and residual bladder urine volume. These tests require urethral catheterization. The disadvantages of catheterization have been amply described (1,2) and justify the need to develop a method to evaluate the lower urinary tract without recourse to catheter ization. Mulrow and associates (3) used 131I-labeled diodrast to estimate residual bladder urine volume without catheterization. They a...

The activity of the magnocellular neurons (MCNs) of supraoptic nucleus (SON) is regulated by a variety of excitatory and inhibitory inputs. Opioids are one of the important compounds that affect these inputs at SON synapses. In this study, whole-cell patch clamp recording of SON neurons was used to investigate the effect of acute and repeated morphine administration on spontaneous inhibitory an...

Ultrascan and actual catheterization volumes were compared on 48 urology, general surgery, and rehabilitation patients. The findings suggest that mean scan and actual urine volumes can be considered equal. In clinical situations where it is necessary to determine residual urine volume, the bladder scan technology is a good alternative to an invasive catheterization procedure.
