Such a large increase occurs especially in cases of starvation and in diabetes mellitus; in both these conditions medications list template order paxil 10 mg without a prescription, the person derives little or no metabolic energy from carbohydrates. Under normal conditions, only about 3 molecules of fatty acid combine with each molecule of albumin, but as many as 30 fatty acid molecules can combine with a single albumin molecule when the need for fatty acid transport is extreme. This shows how variable the rate of lipid transport can be under different physiological conditions. Lipoproteins-Their Special Function in Transporting Cholesterol and Phospholipids In the postabsorptive state, after all the chylomicrons have been removed from the blood, more than 95% of all the lipids in the plasma are in the form of lipoprotein. These lipids are small particles-much smaller than chylomicrons, but qualitatively similar in composition-containing triglycerides, cholesterol, phospholipids, and protein. The total concentration of lipoproteins in the plasma averages about 700 mg per 100 ml of plasma-that is, 700 mg/dl-and can be broken down into the following individual lipoprotein constituents: mg/dl of Plasma Cholesterol Phospholipids Triglycerides Protein 180 160 160 200 Types of Lipoproteins. Almost all the lipoproteins are formed in the liver, which is also where most of the plasma cholesterol, phospholipids, and triglycerides are synthesized. The primary function of the lipoproteins is to transport their lipid components in the blood. The other lipoproteins are especially important in different stages of phospholipid and cholesterol transport from the liver to the peripheral tissues or from the periphery back to the liver. Fat Deposits Large quantities of fat are stored in two major tissues of the body, the adipose tissue and the liver. Adipose Tissue A major function of adipose tissue is storage of triglycerides until they are needed to provide energy elsewhere in the body. Additional functions are to provide heat insulation for the body, as discussed in Chapter 74, and secretion of hormones, such as leptin and adiponectin, which affect multiple body functions, including appetite and energy expenditure, as discussed in Chapter 72. The fat cells (adipocytes) of adipose tissue are modified fibroblasts that store almost pure triglycerides in quantities as great as 80% to 95% of the entire cell volume. When the tissues are exposed to prolonged cold, the fatty acid chains of the cell triglycerides, over a period of weeks, become either shorter or more unsaturated to decrease their melting point, thereby always allowing the fat to remain in a liquid state. This characteristic is particularly important because only liquid fat can be hydrolyzed and transported from the cells. Fat cells can synthesize very small amounts of fatty acids and triglycerides from carbohydrates; this function supplements the synthesis of fat in the liver, as discussed later in the chapter. As discussed earlier, large by the overall rate at which lipids are being used for energy. The liver may also store large amounts of lipids in people who are obese or have lipodystrophy, a condition characterized by atrophy or genetic deficiency of adipocytes. In both of these conditions, excess fat that cannot be stored in adipose tissue accumulates in the liver and, to a lesser extent, in other tissues that normally store minimal amounts of lipids. The liver cells, in addition to containing triglycerides, contain large quantities of phospholipids and cholesterol, which are continually synthesized by the liver. Also, the liver cells are much more capable of desaturating fatty acids than are other tissues, and thus liver triglycerides normally are much more unsaturated than the triglycerides of adipose tissue.

It is composed of three main types of cells: (1) mucous neck cells symptoms after conception paxil 40 mg purchase, which secrete mainly mucus; (2) peptic (or chief) cells, which secrete large quantities of pepsinogen; and (3) parietal (or oxyntic) cells, which secrete hydrochloric acid and intrinsic factor. Secretion of hydrochloric acid by the parietal cells involves special mechanisms, as follows. Mucous neck cells Oxyntic (parietal) cell Canaliculi Secretion When stimulated, the parietal cells secrete an acid solution that contains about 160 mmol/L of hydrochloric acid, which is nearly isotonic with the body fluids. At this pH, the H+ concentration is about 3 million times that of the arterial blood. To concentrate the H+ this tremendous amount requires more than 1500 calories of energy/L of gastric juice. The hydrochloric acid is formed at the villuslike projections inside these canaliculi and is then conducted through the canaliculi to the secretory end of the cell. To produce a concentration of H+ as great as that found in gastric juice requires minimal backleak into the mucosa of the secreted acid. If this barrier is damaged by toxic substances, such as occurs with excessive use of aspirin or alcohol, the secreted acid does leak down an electrochemical gradient into the mucosa, causing stomach mucosal damage. The Basic Factors That Stimulate Gastric Secretion Are Acetylcholine, Gastrin, and Histamine. In comparison, both gastrin and histamine strongly stimulate acid secretion by parietal cells but have little effect on the other cells. Thus, most of the K+ and Na+ in the canaliculus is reabsorbed into the cell cytoplasm, and H+ takes their place in the canaliculus. The hydrochloric acid is then secreted outward through the open end of the canaliculus into the lumen of the gland. Water passes into the canaliculus by osmosis because of extra ions secreted into the canaliculus. However, as soon as it comes in contact with hydrochloric acid, it is activated to form active pepsin. In this process, the pepsinogen molecule, having a molecular weight of about 42,500, is split to form a pepsin molecule, having a molecular weight of about 35,000. Pepsin functions as an active proteolytic enzyme in a highly acidic medium (optimum pH, 1. Hydrochloric acid is as necessary as pepsin for protein digestion in the stomach, as discussed in Chapter 66. The substance intrinsic factor, which is essential for vitamin B12 absorption in the ileum, is secreted by the parietal cells along with the secretion of hydrochloric acid. When the acid-producing parietal cells of the stomach are destroyed, which frequently occurs in persons with chronic gastritis, not only does achlorhydria (lack of stomach acid secretion) develop, but pernicious anemia also often develops because of failure of red blood cell maturation in the absence of vitamin B12 stimulation of the bone marrow. Instead, they contain mostly mucous cells that Chapter 65 Secretory Functions of the Alimentary Tract are identical with the mucous neck cells of the oxyntic glands. These cells secrete a small amount of pepsinogen, as discussed earlier, and an especially large amount of thin mucus that helps to lubricate food movement, as well as to protect the stomach wall from digestion by the gastric enzymes.
Since 1 950 medicine hollywood undead buy 30 mg paxil with visa, autoimmune adrenalitis with adrenal atrophy has accounted for about 80% of cases. It is associ ated with a high incidence of other immunologic and autoim mune endocrine disorders (see later). Primary adrenocortical insuf ficiency, or Addison disease, is uncommon, with a reported preva lence of 3 5 to 1 40 per million population. The diagnosis is generally made in ill patients with significant symptoms of adrenal dys function. The adrenal glands have a rich arterial blood supply, but they are drained by a single vein. Adrenal vein thrombosis may occur during periods of stasis or turbulence, thereby increasing adrenal vein pressure and resulting in a vascu lar dam. This causes hemorrhage into the gland and is followed by adrenocortical insufficiency. Most patients with adrenal hemorrhage have been taking anti coagulant therapy for an underlying coagulopathy or are predis posed to thrombosis. Heparin-induced thrombocytopenia syndrome may be accompanied by adrenal vein thrombosis and re ks fre fre. Glucocorticoid therapy is the most common cause of secondary adrenocortical insufficiency. A normal plasma cortisol response to hypoglycemia excludes adrenal insuf ficiency and decreased pituitary reserve. Thus, patients with normal responses do not require cortisol therapy during illness or surgery. The adrenal medulla is preserved, although cortical cells are largely absent, show degenerative changes, and are surrounded by a fibrous stroma and the characteristic lymphocytic infiltrates. There are two different syndromes in which autoimmune adrenal insufficiency may occur. This is generally an autosomal recessive disorder that usually presents in childhood and is accompanied by hypoparathyroidism, adrenal failure, and mucocutaneous candi diasis. These patients have impaired deletion of auto-reactive T cells during T cell development in the thymus. Other less common related disorders include alopecia areata, vit iligo, primary hypogonadism, pernicious anemia, and celiac dis ease. I nfections Although tuberculosis is a common cause of primary adrenal insufficiency in the rest of the world, it is a rare cause of this problem in the United States. Clinically significant adrenal insufficiency appears to occur in only about 5o/o of patients with disseminated tuberculosis.
