	Excretion: Pharmacokinetics: Merck Manual Professional
		The biliary system contributes to excretion to the degree that drug is not reabsorbed from the GI tract.
		Generally, the contribution of intestine, saliva, sweat, breast milk, and lungs to excretion is small, except for exhalation of volatile anesthetics.
		Biliary excretion eliminates substances from the body only to the extent that enterohepatic cycling is incomplete—when some of the secreted drug is not reabsorbed from the intestine.

	Excretion - Wikipedia, the free encyclopedia

	excretion -- Britannica Concise Encyclopedia - The online encyclopedia you can trust!
		Excretion is a general term referring to the separation and throwing off of waste materials or toxic substances from the cells and tissues of a plant or animal.
		The excretion of wastes and the control of the chemical composition of the internal environment are largely effected by kidneys, although other parts of the body, including the gills, may play an important role.
		Brief information on this condition in which the body is in an acidic state, caused by abnormal excretion of acid from the distal tubule of the kidney.

	NEJM -- Low urinary chiro-inositol excretion in non-insulin-dependent diabetes mellitus
		The urinary excretion of chiro-inositol was much lower in the patients with NIDDM (mean [+/- SE], 1.8 +/- 0.8 mumol per day) than in the normal subjects (mean, 84.9 +/- 26.9 mumol per day; P less than 0.01).
		In contrast, the mean urinary myo-inositol excretion was higher in the diabetic patients than in the normal subjects (444 +/- 135 vs. 176 +/- 46 mumol per day; P less than 0.05).
		There was no correlation between chiro-inositol excretion and the age, sex, or weight of the diabetic patients, nor was there any correlation between urinary chiro-inositol and myo-inositol excretion in either group.

	EFFECTS OF CORN AND(OR) SOYBEAN MEAL ON NITROGEN AND PHOSPHORUS EXCRETION OF GROWING PIGS
		Six groups of four littermate barrows with an average initial weight of 29.4 kg were used to determine nitrogen and phosphorus excretion and the magnitude of deviation from minimal excretion due to corn, soybean meal (SBM), or a combination of corn and SBM.
		However, in a typical corn-soybean meal diet for growing pigs, the excretion of nitrogen and phosphorus attributed to corn or soybean meal is similar.
		For the swine industry, several methods of reducing N and P excretion have been proposed and include phase feeding (Lenis, 1989), use of synthetic amino acids (Carter, 1996), formulating diets on a digestible amino acid basis (Chung and Baker, 1991), and use of enzymes such as phytase (Cromwell, 1991).

	Potassium Bicarbonate Reduces Urinary Nitrogen Excretion
		Net acid excretion was calculated as the sum of the excretion rates of titratable acid and ammonium minus that of bicarbonate.
		Similarly, because urine flow was not reduced, reduced urea excretion was not attributable to increased passive urea absorption secondary to increased renal water reabsorption.
		Fecal N excretion is a small fraction (<12%) of the total N excretion (25), however, and does not change with alkali administration (8).

	Evaluation of Urinary Porphyrin Excretion in Neonates Born to Mothers Exposed to Airborne Hexachlorobenzene (Site not responding. Last check: )
		Our objectives were to analyze urinary porphyrin excretion and HCB in maternal serum and fetal cord blood in neonates born in a village (Flix) near a chlorinated solvent factory, to detect possible adverse effects in urinary porphyrin excretion caused by prenatal exposure, and to assess their relationship with HCB blood levels.
		The present study is the first to analyze the urinary porphyrin excretion in human neonates in relation to HCB levels in cord blood and maternal serum.
		Therefore, the greater CPIII excretion detected in the exposed population may be explained by the deleterious effect of tobacco smoking.
