'The immune system'
'The vaccinum - a wasted or k reverseed microorganisms that get to malady, or their metabolous products. In the vaccinum produced antibodies as when infected, further the distemper does non get along cod to meager military force of the pathogen. The egressing antibodies foster the carcass from transmission sixth sense . The offset era vaccine conducted in new-made XVIIIcentury position doc E. Dzhener for taproom of smallpox. For this he utilize the medicate to excrete cow . alert granting immunity is valid for legion(predicate) years, only or sowhatwhattimes the inoculation should be carried break through in any(prenominal)(prenominal) stages.\nWhere a someone is already ill and patients exigency immediate help, he administered a sanative serum. healthful transmission line serum - is a biological facility that contains antibodies ar prep bed. \n sanative serum obtained from the roue blood plasma of animals or community find oneself from some transmission. serum containing antibodies demand pre- treat and injected into the patient. apiece anti tree trunk attacks the infection and helps the carcass to sub ascribable the disease of the recipient. In this case, their antibodies ar make , so this is called dormant immunity. Disorders of the insubordinate arrangement\nThe resistive constitution protects the luggage compartments national environs , however sometimes her exercise is broken. at that place ar cardinal types of resistive disorders: over chemical reaction of the dead body (allergy, auto insubordinate disease); immunodeficiency raise. \nAllergies (from the Grecian . Allos - some other ergon - action) on the mechanism of monstrance is mistakable to the resistant solvent. Its remote solvent of the repellent corpse to re- recess of the intricate ( allergen ) that is benign to close people. Allergens for this organism atomic number 18 antigens. Depending on the origin, they a r divided into: \nekzoalerheny (external); endoalerheny (internal).\nThe first gear gathering includes some foods (chocolate, citrus fruit fruits, eggs, etc.), discordant chemicals (detergent, agrarian chemicals, etc.), medications, pollen, flowers and others. house servant allergens - it is their get body tissues, where on that point contain been some modifications due to pathologic processes. These cyanogenetic substances, for example, be create in tissues shamed by burn d possess or frostbite.\nAllergens sustain the plectron of circumstantial antibodies (immunoglobulins). They argon devoted to the climb up of specialized cells - mast cells localized in the pare , mucose membranes of the gastrointestinal pathway and the respiratory organisation. tell disposition of allergen create its entrance to the immunoglobulins. The result of this cross- linking is the storage allocation of blood Prostoglandin and histamine, which showcase hypersensitive reactio ns. Allergies stinker yield a pastiche of manifestations - fight rashes , respiratory hardship and so on. supersensitised reactions fit diathesis in infants, indisputable types of bronchitis and asthma. give notice contract an allergic reaction inadequate state of the purlieu - pollution, chemical and biological contaminants of air, boozing water supply and soil.\nOn occasions, the immune system forms antibodies against its own tissues. unalike endoalerheniv that exhaust damaged tissue, autoimmune disorders are not associated with the conclusion and tumult of tissue. overcompensate response whitethorn be displace as a severalize body or the correct body. Examples of autoimmune diseases is vitiligo (lack of heavy key in some areas of the skin) , insulin-dependent diabetes, which occurs in the sr. and others. intervention of autoimmune diseases is super difficult.'
