	Brain Anoxia or Hypoxia
		Specifically, anoxia is a condition in which there is an absence of oxygen supply to an organ's tissues although there is adequate blood flow to the tissue.
		Anoxia and hypoxia, however, are often used interchangeably -- without regard to their specific meanings -- to describe a condition that occurs in an organ when there is a diminished supply of oxygen to the organ's tissues.
		Anoxia and hypoxia may be caused by a number of events, such as smoke or carbon monoxide inhalation, high altitude exposure, strangulation, anesthetic accidents, or poisoning.

	Anoxia
		Anoxia is a condition characterized by an absence of oxygen supply to an organ or a tissue.
		Affinity anoxia involves a defect in the chemistry of the blood such that the hemoglobin can no longer pick up as much oxygen from the air, even though the quantities are normal, reducing how much is delivered to the tissues.
		However, some forms of anoxia do not increase lactic acid concentrations in the blood and some increases in lactic acid levels are not associated with anoxia, so an elevated value for this test is only suggestive of an anoxic or hypoxic condition.

	Anoxia/Hypoxia
		DESCRIPTION: Specifically, anoxia is a condition in which there is an absence of oxygen supply to an organ's tissues although there is adequate blood flow to the tissue.
		Anoxia and hypoxia, however, are often used interchangeably--without regard to their specific meanings--to describe a condition that occurs in an organ when there is a diminished supply of oxygen to the organ's tissues.
		TREATMENT: Treatment of anoxia and hypoxia consists of establishing an adequate airway as soon as possible, using enough oxygen to saturate the blood, supporting the cardiovascular system as needed, and preventing or treating pneumonia.

	eSynopsis of Anoxia of the Brain
		•Anoxia is due to lack of oxygen transport to the brain
		•Anoxia interferes with the function of neurons causing swelling of mitochondria due to loss of their ability to process glucose and lack of energy production for the use of other organelles and membranes in the cells.
		•Anoxia is comman in patients exposed to CO in fires and patients who develop a cardiopulmonary arrest, particularly out of the hospital when CPR is not begun within 4 minutes.

		Tissue-specific controls on carbohydrate metabolism regulate the response to anoxia in goldfish (Carassius auratus) and bring about the overall metabolic rate depression that is a key feature of anoxia tolerance.
		The effect of anoxia (24 h at 7oC under N2/ CO atmosphere) on glycogen phosphorylase activity and on the content of fructose-2,6-bisphosphate was determined in eight tissues (liver, brain, kidney, gill, spleen, heart, and red and white skeletal muscle) of goldfish.
		Anoxia resulted in an increase in the percentage of phosphorylase in the active a form in brain but significantly reduced phosphorylase-a content in liver, kidney, spleen, and heart; total phosphorylase activity (a + b) was also reduced during anoxia in liver and gill.

		The importance of carbohydrates in rice seeds exposed to anoxia was evaluated in two rice cultivars differing in anoxia tolerance.
		Glucose feeding during anoxia of half seeds increased survival and plant height and demonstrated that reduced survival was largely the result of low carbohydrate supply and not of seed wounding.
		The better growth under anoxia in larger seeds, in more dense seeds, and in half seeds supplied with glucose supports the importance of seed carbohydrates in seedling establishment under anoxia.

	Resistance of isolated pulmonary mitochondria during in vitro anoxia/reoxygenation. (Site not responding. Last check: 2007-10-09)
		Mitochondrial respiratory parameters were determined in isolated mitochondria before anoxia (control), after 5-45 min anoxia followed by 5 min reoxygenation, and after 25 or 40 min of in vitro incubation in order to follow the in vitro aging of mitochondria during respiratory assays.
		Respiratory parameters measured after anoxia/reoxygenation did not show any oxidative phosphorylation dysfunction, indicating a high resistance of pulmonary mitochondria to in vitro anoxia/reoxygenation (up to 45 min anoxia).
		These results indicate that mitochondria are not directly responsible of their oxidative phosphorylation damage observed after in vivo ischemia (K. Willet et al., Transplantation 69 (2000) 582) but are a target of others cellular injuries leading to mitochondrial dysfunction in vivo.
