Critical Care Medicine, 2007
Sepsis is a severe condition in critically ill patients and is considered an arginine deficiency state. The rationale for arginine deficiency in sepsis is mainly based on the reduced arginine levels in sepsis that are associated with the specific changes in arginine metabolism related to endothelial dysfunction, severe catabolism, and worse outcome ...

Localized exogenous ochronosis
Journal of the American Academy of Dermatology, 1983A 58-year-old black woman with localized exogenous ochronosis due to the use of a proprietary hydroquinone bleaching cream is described. Histologic studies, including electron microscopy, are presented. The differential diagnosis of blue-black hyperpigmentation is discussed. The literature on ochronosis, both endogenous (alkaptonuria) and exogenous, is

Exogenous Respiration in Nitrobacter
Nature, 1960DURING the course of an investigation of the oxidation of nitrite by the nitrite-oxidizing bacterium, Nitrobacter, it was noted that the addition of sodium nitrite but not sodium nitrate to heavy cell suspensions caused the immediate appearance of reduced cytochrome bands at 590, 551 and 513 mµ when viewed in the hand spectroscope1.

Endogenous and exogenous nitrates
Acta Anaesthesiologica Scandinavica, 1992The endothelium‐derived relaxing factor (EDRF) is nitric oxide (NO) or a closely related nitrosothiol derivative. It is formed from the amino acid, L‐arginine. NO is rapidly inactivated locally and is instantly destroyed by haemoglobin when released into the blood stream.
