Il sistema immunitario si evoluto per discriminare il self dal non self. I due bracci dell'immunit lavorano a stretto contatto: il sistema immunitario innato pi attivo nelle prime fasi della risposta immunitaria, mentre l'immunit adattativa diventa progressivamente dominante nel tempo. I principali effettori dell'immunit innata sono il complemento, i granulociti, i monociti/macrofagi, i linfociti natural killer, i mastociti e i basofili. I principali effettori dell'immunit adattativa sono i linfociti B e T. I linfociti B producono anticorpi; i linfociti T funzionano come cellule helper, citolitiche e regolatrici (soppressori). Queste cellule sono importanti nella normale risposta immunitaria alle infezioni e ai tumori, ma mediano anche il rigetto dei trapianti e l'autoimmunit . Le immunoglobuline (anticorpi) sulla superficie dei linfociti B sono recettori per una grande variet di conformazioni strutturali specifiche.

Das Immunsystem hat sich so entwickelt, dass es zwischen selbst und fremd unterscheiden kann. Die beiden Arme der Immunit t arbeiten eng zusammen, wobei das angeborene Immunsystem zu Beginn einer Immunreaktion am aktivsten ist und die adaptive Immunit t mit der Zeit immer dominanter wird. Die wichtigsten Effektoren der angeborenen Immunit t sind Komplement, Granulozyten, Monozyten/Makrophagen, nat rliche Killerzellen, Mastzellen und Basophile. Die wichtigsten Effektoren der adaptiven Immunit t sind B- und T-Lymphozyten. B-Lymphozyten stellen Antik rper her; T-Lymphozyten fungieren als Helfer-, zytolytische und regulatorische (Suppressor-)Zellen. Diese Zellen sind wichtig f r die normale Immunreaktion auf Infektionen und Tumore, vermitteln aber auch die Absto ung von Transplantaten und Autoimmunit t. Die Immunglobuline (Antik rper) auf der Oberfl che der B-Lymphozyten sind Rezeptoren f r eine Vielzahl spezifischer Strukturkonformationen.

An 'image' is a reproduction, representation or imitation of the physical form of a person or thing. It is derived from Latin word for imitate. The inventor of photography was probably the Chinese about 3000 years ago. They possessed a light sensitive material that transferred the images of leaves onto the surface of pots and vases. Englishman William Henry Fox Talbot in 1841 developed negative and positive approach of image production. Image is artificial imitation of external form of object and refers to picture and likeness of the object. Receptor refers to something that responds to the stimulus. Image receptors used in dentistry today are film, film-screen combinations, the electronic sensors used in digital imaging and computed tomography (CT). Some medical imaging systems, such as fluoroscopy systems, use X-rays as the energy source without film.

The immune system evolved to discriminate self from nonself. The two arms of immunity work closely together, with an innate immune system being most active early in an immune response and adaptive immunity becoming progressively dominant over time. The major effectors of innate immunity are complement, granulocytes, monocytes/macrophages, natural killer cells, mast cells, and basophils. The major effectors of adaptive immunity are B and T lymphocytes. B lymphocytes make antibodies; T lymphocytes function as helper, cytolytic, and regulatory (suppressor) cells. These cells are important in the normal immune response to infection and tumors, but also mediate transplant rejection and autoimmunity. Immunoglobulins (antibodies) on the B lymphocyte surface are receptors for a large variety of specific structural conformations.

In modern society, a number of diseases have been on the rise with changing lifestyles or environment influences including diet and psychoemotional stress. Such impact may continue to the development and prevalence of various diseases including Arteriosclerosis, Cancer, Chronic liver disease, Cirrhosis, Chronic Obstructive Pulmonary disease (COPD), Diabetes, Hypertension, Heart diseases, Stroke, Recurrent Aphthous Stomatitis, Asthma, Obesity, Depression and Vascular Dementia. In an otherwise healthy individual, there are few conditions that develop in the oral mucosa. Recurrent aphthous ulcer (RAU) is the one of most common inflammatory ulcerative condition of the oral mucosa. The word "aphthous" has been derived from a Greek word "aphtha" which means ulceration. The worldwide prevalence of oral ulcer is 4% out of which 25% are aphthous ulcer, thus becoming the most oral ulcer. It usually affects the nonkeratinized or poorly keratinized surfaces of the oral mucosa such as labial and buccal mucosa, maxillary and mandibular sulcus, free gingiva, soft palate, floor of mouth and ventral surface of the tongue. They are usually painful, shallow round ulcers with an erythematous halo.

Le malattie ematologiche comprendono principalmente disturbi legati ai globuli rossi, ai globuli bianchi e alle piastrine, che sono i principali componenti del sangue. Per escludere la presenza di malattie ematologiche in un determinato paziente, l'anamnesi deve iniziare con i questionari medici standard; necessario indagare su qualsiasi precedente episodio di sanguinamento prolungato dopo un intervento chirurgico o una lesione, su qualsiasi sanguinamento spontaneo o su ecchimosi frequenti. L 'anamnesi farmacologica molto importante e deve essere registrata in dettaglio per sapere se il paziente sta assumendo anticoagulanti.

As doen as hematol gicas incluem principalmente perturba es relacionadas com os gl bulos vermelhos, os gl bulos brancos e as plaquetas, que s o os principais componentes do sangue. Para excluir a presen a de doen as hematol gicas num determinado doente, a anamnese deve come ar com question rios m dicos padr o; deve ser feita uma investiga o sobre qualquer epis dio anterior de hemorragia prolongada ap s uma cirurgia ou ferimento, qualquer hemorragia espont nea ou n doas negrasfrequentes. A hist ria medicamentosa muito importante e deve ser registada em pormenor para saber se o doente est a tomar anticoagulantes.

Zu den h matologischen Erkrankungen geh ren vor allem St rungen im Zusammenhang mit den roten und wei en Blutk rperchen sowie den Blutpl ttchen, die die Hauptbestandteile des Blutes sind. Um das Vorhandensein h matologischer Erkrankungen bei einem bestimmten Patienten auszuschlie en, sollte die Anamnese mit medizinischen Standardfrageb gen beginnen; es sollte nach fr heren l ngeren Blutungsepisoden nach Operationen oder Verletzungen, nach spontanen Blutungen oder h ufigen Bluterg ssen gefragt werden. DieMedikamentenanamnese ist sehr wichtig und sollte detailliert aufgezeichnet werden, um zuerfahren, ob der Patient Antikoagulanzien einnimmt.

La pratique consistant placer une petite quantit de tabac sans fum e ou de tabac chiquer dans la cavit buccale et la laisser en place pendant de longues p riodes semble se r pandre sur les campus des coll ges, des lyc es et des universit s comme une habitude socialement acceptable et populaire. De nombreux rapports dans la litt rature ont d crit les changements buccaux qui semblent tre associ s l'utilisation du tabac sans fum e chez les adultes. La manifestation buccale la plus r pandue de l'utilisation du tabac sans fum e (ST) est une l sion blanche de la muqueuse l'endroit o l'on a l'habitude de placer le tabac.

Hematologic diseases mainly include disorders related to red blood cells, white blood cells and platelets which are the major components of blood. To rule out presence of hematologic diseases in a given patient, history should begin with standard medical questionnaires; Enquiry should be done about any previous prolonged bleeding episode post-surgery or injury, any spontaneous bleeding or frequent bruising. Drug history is very important and should be recorded in detail to know if the patient is on anticoagulants.
