urea and Urinary Calculi studies

pseudourea: clinical use; structure
isourea : A carboximidic acid that is the imidic acid tautomer of urea, H2NC(=NH)OH, and its hydrocarbyl derivatives.

Urinary Calculi: Low-density crystals or stones in any part of the URINARY TRACT. Their chemical compositions often include CALCIUM OXALATE, magnesium ammonium phosphate (struvite), CYSTINE, or URIC ACID.

Research Excerpts

Excerpt	Relevance	Reference
" It was found that vanadyl treatment did not produce persistent changes in plasma aspartate aminotransferase, alanine aminotransferase, and urea, specific morphological abnormalities in the brain, thymus, heart, lung, liver, spleen, pancreas, kidney, adrenal, or testis, or abnormal organ weight/body weight ratio for these organs in either non-diabetic or diabetic animals."	3.69	Toxicity studies on one-year treatment of non-diabetic and streptozotocin-diabetic rats with vanadyl sulphate. ( Dai, S; McNeill, JH; Thompson, KH; Vera, E, 1994)
" Urinary excretion rates of calcium, sodium, chloride, potassium, urinary calcium/creatinine index, the fractional excretion of sodium, potassium and uric acid, the creatinine clearance and serum values of creatinine, urea, uric acid, electrolytes, total proteins, parathormone (intact molecule), plasma renin activity, aldosterone, glucose, and insulin (fasting and after an oral glucose load) were performed in every patient and control subject."	3.69	Urinary calcium excretion in treated and untreated essential hypertension. ( Navarro-Antolin, J; Orte, L; Ortuño, J; Quereda, C; Sabater, J; Villafruela, JJ, 1996)
" In the rat these same dosage levels produced urinary inhibitory activity equivalent to 16 to 140 fold that required for 90 per cent urease inhibition."	1.25	Benurestat, a urease inhibitor for the therapy of infected ureolysis. ( Andersen, JA, 1975)
