Suprarenal glands

Hypersensitivity to these agents depressed sodium or potassium serum levels marked kidney and liver disease or dysfunction suprarenal gland failure hyperchloremic acidosis adrenocortical insufficiency severe pulmonary obstruction with inability to increase alveolar ventilation since acidosis may be increased (dichlorphenamide) cirrhosis (acetazolamide, methazolamide) long-term use in chronic noncongestive angle-closure glaucoma. 

Another example is the tissues that are particularly rich in vitamin C, for example, the cortex of the suprarenal gland or the lens here, vitamin C fulfills both antioxidative functions and metabolic ones as it helps in the formation of collagen structures. Approximately 40% of the body s ascorbate is stored in skeletal muscle because this tissue is relatively abundant and its cellular concentration is tenfold higher than the plasma level. Similarly, the intracellular ascorbate concentration in the brain (3 mM) greatly exceeds the level in the extracellular fluid (200-400 zM). The majority of ascorbate is stored in the astroglial cells that are capable of reducing great quantities of DHAA to ascorbate, which then becomes available for release back into the extracellular fluid. 

During the 1930 s, several seientists isolated eortisone among other adrenoeortieal hormones from the suprarenal glands of cattle. Kendall et al. [12-14] isolated 8 steroidal hormones (cortisone being Kendall s compound E), while Wintersteiner et al. [15,16] isolated 4 compounds (Wintersteiner s compound F was cortisone). Reichstein [17] isolated 31 substances, with his compound Fa being cortisone. Kuizenga and Cartland [ 18] isolated 5 substances, and Wettstein et al. [ 19] isolated 18 hormones. 

In humans, the kidneys are located in the posterior part of the abdomen. There is one on each side of the spine the right kidney sits just below the liver, the left below the diaphragm and adjacent to the spleen. Above each kidney is an adrenal gland (also called the suprarenal gland). The asymmetry within the abdominal cavity caused by the liver results in the right kidney being slightly lower than the left one.

The major mechanisms involve the HPA axis. The hypothalamus, pituitary, and adrenals that form the HPA axis also collectively form the neuroendocrine control system. The hypothalamus and pituitary gland, adjacent to each other and connected by nerve fibers, are part of the evolutionary old brain —a group of anatomic regions also present in lower animals. The adrenal glands (suprarenal glands) are far away from the brain at the top of each kidney. 

Abel and Fuerth isolated independently the active principle from the suprarenal glands which were later on established as the same compound now known as adrenaline. It may be synthesized conveniently by several methods, but a very common process is described under ... 

Isolated for the first time in 1775 from gallstones by the physician Benjamin Gottlob Friedrich Conradi (Jena, Germany), cholesterol occurs everywhere in the human body. With high levels especially in the brain, the spinal cord and the suprarenal glands, the total amount of cholesterol in an adult adds up to some 240 grams. Invertebrates, on the other hand, synthesise in addition 24-dehydro-cholesterol in considerable quantity.

Another class of substances of importance in the activity of the human body consists of the hormones, which are substances that serve as messengers from one part of the body to another, moving by way of the body fluids. The hormones control various physiological processes. For example, when a man is suddenly frightened, a substance called epinephrine (also called adrenalin) is secreted by the suprarenal glands, small glands that lie just above the kidneys. The formula of epinephrine is... 

The molar proportion of catecholamines to adenosine triphosphate in the medulla of the normal human suprarenal gland is about 1 4-5, whereas in tissue from a phaeochromocytoma a proportion of 1 10-35 was found. This observation, coupled with that of decreased granular storage of catecholamines in the cells of a phaeochromocytoma, point to a disturbance in the storage mechanisms of cells from chromaffine tissue tumours. (989,1469) increased secretion from such tumours is probably connected with this disturbance.
