Mesenteric Adenitis
Adenitis is a general term for an inflammation of a gland. Often it is used to refer to lymphadenitis which is the inflammation of a lymph node. Classification Lymph node adenitis ''Lymph adenitis'' or ''lymph node adenitis'' is caused by infection in lymph nodes. The infected lymph nodes typically become enlarged, warm and tender. A swelling of lymph nodes due to growth of lymph cells is called lymphadenopathy. Types include: * Neck ** Cervical adenitis is an inflammation of a lymph node in the neck. ** Tuberculous adenitis ( scrofula) is a tuberculous infection of the skin of the neck caused by ''Mycobacterium tuberculosis''. Non-tuberculous adenitis can also be caused by ''Mycobacterium scrofulaceum'' or ''Mycobacterium avium''. * Abdomen ** Mesenteric adenitis is an inflammation of the mesenteric lymph nodes in the abdomen.

Inflammation
Inflammation (from la, wikt:en:inflammatio#Latin, inflammatio) is part of the complex biological response of body tissues to harmful stimuli, such as pathogens, damaged cells, or Irritation, irritants, and is a protective response involving immune cells, blood vessels, and molecular mediators. The function of inflammation is to eliminate the initial cause of cell injury, clear out necrotic cells and tissues damaged from the original insult and the inflammatory process, and initiate tissue repair. The five cardinal signs are heat, pain, redness, swelling, and Functio laesa, loss of function (Latin ''calor'', ''dolor'', ''rubor'', ''tumor'', and ''functio laesa''). Inflammation is a generic response, and therefore it is considered as a mechanism of innate immune system, innate immunity, as compared to adaptive immune system, adaptive immunity, which is specific for each pathogen. Too little inflammation could lead to progressive tissue destruction by the harmful stimulus (e.g. b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
