Tubercle is different in _'s general knowledge of tuberculosis
Tubercle (Sarcoidosis) Also calling one kind of tumours of meat has names such as one kind of tumour Schaumann benign lymphocytic granulation swollen diseases of Boeck meat and Besnier and a kind of lupus of hemorrhoid,etc.. It is a kind of chronic granulation swollen disease. Solid to have broken to have the intersection of skin and damage of subjective symptoms also can invade mucous membrane, lymph node, skeleton, organ inside the body and claim the intersection of whole body and sarcomatous disease outside while being routed. Thought tubercle was one of the tuberculosis, but was lack of evidence in the past. Still propose other not typical branched bacillus are the cause of disease. Infect by virus while being other and influence of inherent cause, fail to be verified. The cause of disease is not clear at present.
Think a disease relates to immunoreaction in recent years. Especially T cells lie between the immunoreaction that is led and play an important role. Under the stimulus of some pathogenic antigen, have activated T cells and macrophages of the sick position. Release the intersection of T and cell that activate a large number of monocyte hasten factor of taking and macrophage visit move to inhibit the factor from, make the monocyte assemble; Release the macrophages activated the leucocyte is lain between plainly - 1, enable T cell division hyperplasia, because early pathological change is soaked as main cells with T cell monocyte, macrophage.
With the development of disease,on produce skin kinds of cell in a large amount,form by typical granulations nodular swollen. On disease later stage, the hyperplasia of fibrous master cell, the extensive fiber appears finally.
Or hypodermis generally happens in the dermis in tubercle. The main change has one kind of cells of skin to soak. Have one kind of cells of cover and assemble in groups, include a few big and small afterbirth or not have big and small afterbirth, have a few lymphocytes around, but no a kind of necrosis of cheese will happen. Cellulose a kind of necrosis happens accidentally to a group of central authorities of cell. Upper the intersection of skin and kinds of the intersection of cell and the intersection of connective tissue and hyperplasia under group, have a liking for silver, dye, can see netted fiber, round and wear upper the intersection of skin and kinds of cell group. Cells can see the small blood vessel in group.
Can see big and small afterbirth in damage these, continue the intersection of little body or star graceful and little body while being accidental. It is an ovate or round to continue the small graceful body, and there is calcification. Because include calcium, dye dark blue. The little body of star is usually dyed with the phosphorus tungsten sour Su wood, the centre is fusco-ferruginous, the star awn is blue, this two small body, can also see in tuberculosis, leprosy in other granulation are swollen, it is not that tubercle is characterized. When the granulation of tubercle is swollen to disappear, upper the intersection of skin and kinds of cell fade, cause fiber take, take shape.
