Clinical syndrome caused by disorders of absorption through the mucous membrane of the small intestine of one or more nutrients. Etiology and pathogenesis. Malabsorption syndrome can be primary (hereditary) or secondary (acquired). Etiology in each case different (absence or reduced activity of lactase, alpha-glucosidase, enterokinase and so on). Among hereditary disturbed intestinal absorption occur disaccharidase deficiency (lactase, saharasia, isomaltase), true celiac disease (intolerance to gliadin), failure enterokinase, intolerance monosaccharides (glucose, fructose, galactose), malabsorption of amino acids (zistinurija, disease Hartnup and others), malabsorption of vitamin B12 and folic acid, and so on, Secondary, or acquired, malabsorption, the companion of many chronic diseases of the stomach and intestines (pancreatitis, hepatitis, intestinal dysbiosis, intestinal infections of dyskinesia, Crohn's disease and others).

PneumosclerosisPNEUMOSCLEROSIS - development in lung connective tissue as a result of nessecities (pneumonia, bronchitis) or specific (tuberculosis, syphilis) inflammatory process, as well as pneumoconiosis, prolonged stagnation in a small circle of blood (mitral stenosis, other heart disease), immunoallergic vasculitis. The formation of connective tissue cell is way less without the presence of cells (hyalinosis). The characteristic localization in areas of carnification nerazreshimaya pneumonia, during the outflow of lymph from the foci of inflammation around the lymphatic vessels, mealberry and bilobular-governmental partitions, peribronchial and perivascular tissue, zapustevanie capillaries and reduction of the capillary bed, Symptoms, duration depend on the underlying disease, with exacerbations which progresses and pneumosclerosis. Gradually decreases the respiratory surface of the lung, develop emphysema, there is a rearrangement of the lung tissue with the formation of bronchiectasis, there is obstruction of blood flow in a small circle with the formation of pulmonary hypertension. The combination of these changes is called pneumoconiosis. The clinical picture of pneumosclerosis (pneumoconiosis) is determined, thus, signs of complications: emphysema, destruction, etc. Читать полностью -->

Old kettles hazardous to health

Old kettles hazardous to healthWater boiled in the kettle old model, may cause or contribute to the development of allergies, experts warn. According to them, the Nickel particles of the coating of the heating elements can cause skin irritation. In a study conducted in Britain, it was found that the Nickel in the water from the old maker really is a risk, albeit low. "Actually, in this case, there is almost no danger, except for people who are overly sensitive to Nickel," said the head of the British drinking water Inspectorate Michael Rosin in an interview with Bi-bi-si. Nickel in water from the old maker really is a risk, albeit low. Inspection of drinking water tested eight kettles with spirals, of which only one floor of the heating element was made of stainless steel, as part of its coverage was not part of the Nickel.

The impact of the computer on human health

The impact of the computer on human healthThe impact of the computer on human health *57r*today there are numerous discussions, the impact of the computer? Is this harmful? And if Yes, how? More dangerous computer, TV, or does it harm no more than ordinary electronic clock? When working with a computer, unlike reading a book, when you can easily find a comfortable position, the person is fully dependent on the position of the display. In addition, the screen as a light source device is active contrast (paper - passive contrast), which is not so strongly dependent on light intensity and angle of incidence. The image on the screen is dynamically updated. Low refresh rate (regeneration) causes the flicker. Usually the person stares at the monitor screen. While ocular and intraocular muscles remain stationary, while they need in a dynamic mode. Читать полностью -->

Stress prolongs life

Stress prolongs lifeScientists believe that a certain type of stress can improve the immune system, fight depression and improve memory. This is because during stress, the adrenal glands, a special hormone called dehydroepiandrosterone, which is a positive effect on our state. According to a recent study, more than our body secretes these hormones, the better we cope with stress, stress. Therefore, those who have adrenal glands produce less dehydropiandrosterone, cope with stress, and they feel worse. The researchers decided to conduct one experience. Old and slow mice were injected dose of the hormone, then they became more active and started to run as fast as young mice. Читать полностью -->
