淋巴组织增生

Through all this test analyse Pathogenicity and Immunological status of ALV-J Inner Mongolia strain, the result showed the infected chickens began to have pathological change of Myelcytomatosis at 3-week: the main pathological changes of acidophile myelocyte were found in bone marrow and between cardiac muscle fibers,and there were many granules in the hyalotome.This kind of oncocyte proliferated in every tissue at different amount, but the cells that proliferated in bone marrow, cardiac muscle fiber, oarium were much more than other tissue, and they often developed neoplasma. At same condition,there were no abnormalty advent in control group, In immunological aspect: the increase of lymphokine and ANAE positive cells showed cell-mediated immunity was strengthend during antineoplastic infection; the emergence of ALV-J antibody of ELISA suggest there was humoral immunity exist at the same time.

结果显示：脾脏PCR检测结果表明1、2两实验组均有阳性病例出现，而对照组全部为阴性，说明实验鸡体内已有ALV-J内蒙株感染；接种病毒后3周龄开始出现骨髓细胞瘤病的病理变化：肝脏、脾脏有程度不同的肿大，镜下观察，骨髓内最早出现了与骨髓细胞相似、形态基本一致的大型圆形或椭圆形、胞核较大多为椭圆形、胞浆内含有大量嗜酸性圆形颗粒的髓细胞样瘤细胞增生，随后通过血流瘤细胞可转移到肝脏、心肌、卵巢或睾丸等组织并形成肿瘤性病灶，而对照组没有出现明显病变；免疫状态方面：以脾脏淋巴因子和ANAE阳性细胞增多说明细胞免疫在抗肿瘤感染过程中增强，ELISA检验实验鸡抗体出现阳性的结果表明同时也存在着体液免疫。

Results: Pigeons exposed to -70°C for 12 min and -90°C for 6 min and 9 min showed slight proliferation of fibrous connective tissue in the perilymphatic space at the site of cryosurgery and presented a selective decrease of the semicircular canal functions.

结果：在-70°C 12 min、-90°C 6 min和9 min显示冷冻处外淋巴间隙纤维组织轻度增生，选择性的半规管功能降低；6例患者经1年4个月至2年5个月随访，5例治疗成功，眩晕消失，1例耳鸣有缓解，4例听力无变化，1例听力下降18 dB。

Debris necrosis of lymph node is not the specific changes of KD. In the tuberculosis of lymph node,① debris necrosis is obvious, but it tends to be caseous nercrosis;② histiocytes, macrophages and foam cells are hyperplasia in the necrotic area or lymph sinus, moreover, epithelioid cells can be found and they tend to be form granuloma;③ numbers of neutrophils infiltrate in the necrotic area;④ the etiologic assay of acid fast bacterium tuberculosis bacterium is positive;⑤ typical clinical manifestation is insufficient.

淋巴结碎屑性坏死并非KD特有病变，诊断KD需先除外有明显碎屑性坏死的淋巴结结核病，后者主要表现：①碎屑性坏死虽明显，但趋于干酪样坏死；②坏死区内或同时在淋巴窦内，组织细胞、巨噬细胞和泡沫细胞增生，并演变为上皮样细胞和趋于肉芽肿形成；③坏死灶内、外可有数量不等的中性粒细胞浸润；④抗酸杆菌／结核杆菌病原学检测阳性；⑤缺乏KD的典型临床过程。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
