 | | One method of quantitatively describing the renal excretion of drugs is by means of the renal clearance value for the drug. | | | The major organ for the excretion of drugs is the KIDNEY. | | | Again, most drugs are filtered from blood in the glomerular, the overall renal excretion however is controlled by what happens in the tubules. |

| | Potassium Bicarbonate Reduces Urinary Nitrogen Excretion |
| | The reason for the difference in response of urea excretion between the studies of Hannaford and Gougeon-Reyburn is not clear. | | | Fecal N excretion is a small fraction (<12%) of the total N excretion (25), however, and does not change with alkali administration (8). | | | Additional mechanisms operate during chronic metabolic acidosis to facilitate renal excretion of ammonium and promote N wasting. |

| | 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. | | | Environmental Health Perspectives (EHP) is a monthly journal of peer-reviewed research and news on the impact of the environment on human health. |

| | CHEST: Aldosterone excretion among subjects with resistant hypertension and symptoms of sleep apnea - clinical ... |
| | While the causality of this association is unknown, it is hypothesized that sleep apnea contributes to the development of resistant hypertension by stimulating aldosterone excretion. | | | Although the study did not allow for determination of causality, we question whether OSA could contribute to the development of resistant hypertension by stimulating aldosterone excretion. | | | The mechanism, however, by which sleep apnea contributes to the development of resistant hypertension remains obscure. |

| | excretion -- Britannica Concise Encyclopedia - The online encyclopedia you can trust! |
| | Four terms are commonly associated with waste-disposal processes and are often used interchangeably, though not always correctly: excretion, secretion, egestion, and elimination. | | | 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. | | | 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. |

| | Excretion & Retention |
| | Therefore, most of the therapeutic measures suggested in Unani healing are aimed to ensure that the food and nutrient substances are fully assimilated and eliminated, or to use various measures and herbal medicines to assist this process if it is impaired. | | | If there is not complete excretion of the by-products of the body, leading to their being retained, diseases can arise. | | | The process of complex digestion according to Unani healing has three stages: digestion, assimilation, and excretion. |

| | Homiostasis and Excretion |
| | Animals constantly bring materials into the body to be metabolized. | | | In fact, many so called "excretory organs" have no role in excretion and are solely osmoregulatory organs. | | | In aquatic organisms the "excretory" organs are usually osmoregulatory organs and excretion is accomplished by diffusion across the gills. |

| | Excretion is the biological process by which an organism chemically separates waste products from its body. | | | The waste products are then usually expelled from the body by elimination. | | | A common misunderstanding is that feces are a product of excretion. |

| | This increased excretion most likely occurred because phosphorus was more available in the casein compared with the SBM. | | | Thus, the purpose of this experiment was to examine the most common forms of energy (corn) and protein (SBM) used in pig diets and their relationship to N and P excretion. | | | Reduction of N excretion also has the potential to alleviate some of the problems associated with offensive odors due to ammonia production. |

| | Pharmacokinetics: Drug Excretion |
| | If renal clearance is not the major pathway of excretion, these factors may have little effect on overall excretion. | | | Renal clearance may become important at higher drug doses when metabolizing enzymes become saturated. | | | The excretion of weak acids can be increased significantly by alkalinizing the urine (sodium bicarbonate); excretion of weak bases can be increased by acidifying the uring (ammonium chloride). |
