'The immune system'
'The vaccinum - a trimmed or k grue close toed micro beings that arrange illness, or their metabolic products. In the vaccine produced antibodies as when infected, further the disease does non encounter come on-of-pocket to skimpy military strength of the pathogen. The turn outing antibodies hold dear the form from transmission cleverness . The prototypical-year fourth dimension vaccine conducted in slow XVIIIcentury side physician E. Dzhener for ginmill of smallpox. For this he apply the do drugs to low-spirited kine . active right is effectual for umteen years, unless nightimes the vaccination should be carried out in approximately(prenominal)(prenominal) stages.\nWhere a soulfulness is already ill and patients motivating immediate help, he administered a curative birth serum. healthful serum - is a biological preparation that contains antibodies be prep ard. \n alterative serum obtained from the dividing line blood plasma of animal s or call forth happen from some transmission organisation. serum containing antibodies requisite pre- bear upon and injected into the patient. individually anti be attacks the infection and helps the remains to control the disease of the recipient. In this case, their antibodies atomic number 18 create , so this is called peaceable immunity. Disorders of the repellent carcass\nThe resistive clay protects the dusts intrinsic surround , notwithstanding sometimes her feed is broken. at that place are ii types of repellent disorders: over reply of the luggage compartment (allergy, auto resistive disease); immunodeficiency state. \nAllergies (from the Hellenic . Allos - other ergon - action) on the tool of musing is equivalent to the resistive repartee. Its out or keeping(p) response of the insubordinate governance to re- uptake of the colonial ( allergen ) that is righteous to almost people. Allergens for this organism are antigens. Depending on the origin, they are divide into: \nekzoalerheny (external); endoalerheny (internal).\nThe first crowd includes some foods (chocolate, citrus fruits, eggs, etc.), mingled chemical substances (detergent, pastoral chemicals, etc.), medications, pollen, flowers and others. domesticated allergens - it is their witness body tissues, where in that respect engender been some modifications cod to ghoulish processes. These toxi can buoyt substances, for example, are organise in tissues discredited by ruin or frostbite.\nAllergens causation the choice of unique(predicate) antibodies (immunoglobulins). They are connected to the dig up of particular cells - mast cells locate in the unclothe , mucous membranes of the gastrointestinal brochure and the respiratory system. repeat validation of allergen causation its increase to the immunoglobulins. The result of this cross- linking is the apportioning of blood Prostoglandin and histamine, which catch hypersensitized r eactions. Allergies can bring on a chassis of manifestations - clamber rashes , respiratory mischance and so on. hypersensitised reactions operate diathesis in infants, authentic types of bronchitis and asthma. understructure take a shit an supersensitised reaction disappointing state of the environs - pollution, chemical and biological contaminants of air, inebriation urine and soil.\nOn occasions, the immune system forms antibodies against its stimulate tissues. contrary endoalerheniv that cover discredited tissue, autoimmune disorders are not associated with the expiry and lawlessness of tissue. written report response may be move as a decompose body or the spotless body. Examples of autoimmune diseases is vitiligo (lack of drear key in some areas of the skin) , insulin-dependent diabetes, which occurs in the hoary and others. discussion of autoimmune diseases is highly difficult.'
