Insulin is readily concentrated from 10 to 50 ml of urine with better than 75% recovery using octadecylsilyl (ODS) silica columns (C18Sep-Pak cartridge) and can then be measured by radioimmunoassay. Fractionation on Sephadex G50 gel filtration reveals that the apparent immunoreactivity corresponds for the most part to 6000 dalton insulin. Renal clearance of insulin in 5 normal subjects does not...

The effect of diet on the enterohepatic recycling of estrogen after oral administration of 1 mg non-radioactive estriol (E3) was studied in six women using contraceptive pills. The women were followed for two consecutive menstrual cycles, firstly on a high fibre diet (HFD) and then changing on to low fibre diet (LFD) during the next cycle, hence each subject acted as its own control. The extent...

In order to gain information on the metabolism of dolichol, the rates of excretion of dolichol and dolichyl phosphate were determined in rats maintained on a dolichol-free diet for 10 days. Analysis of fecal samples collected every 48 h yielded mean output values of 9.0 +/- 1.4 and 20.7 +/- 3.0 micrograms/rat/day of dolichol and dolichyl phosphate, respectively. Urinary output rates were 0.56 +...

Urine Drainage Bag (UDB) has been frequently acknowledged by patients who are suffering from urine incontinence, urinary retention, tract infections, and urological surgeries in which a patient is impotent to out-migration. In ICUs, physiological parameters of measured monitoring devices. These devices can also supervise whether the values lie within pre-established range set clinician. Just li...

cystoscopy and urinary cytology are currently the basis for diagnosis and ‎follow-up of bladder tumors. research to find a sensitive and specific tumor ‎marker for diagnosis of bladder tumor is actively underway, however, due to low sensitivity ‎and high cost of cytology. this cross-sectional study was performed in 65 patients to evaluate whether urinary bladder ‎cancer (ubc) antigen level can ...

background in order to detect nephropathy, measurement of total (24 hrs) urinary albumin or albumin/creatinin ratio in random urine samples is being recommended. but methods of albumin measurement are not available in all laboratories and also cost about 6 times more than that of urinary total protein measurement. objectives this study was performed to determine appropriate cut off point in 24 ...

We examined the time course and extent to which central and peripheral mechanisms contribute to the short-term effects of a 500-mg oral dose of alpha-methyldopa on supine mean arterial pressure, cardiac output, and total peripheral resistance, as well as its effects on total urinary excretion of norepinephrine and its metabolites, in five subjects with essential hypertension. Total peripheral r...
