肉芽瘤

HRCT can correctly diagnose and orientate mastoiditis, but can not easily distinguish granullomatous from cholesteatoma.

由于HRCT能清晰显示颞骨结构，对中耳乳突炎性病变发现及定位较准确，对胆脂瘤和肉芽肿型鉴别仍有一定困难。

Result of HE and special dye1.1 result of HE More cells are found in subsequent cholesteatoma. Cholesterol crystal, both sequestrum and neogenesis bone , gland metaplasia, Polykaryocyte are found in subepidermis of subsequent cholesteatoma.

结果1、HE染色结果：可见后天性胆脂瘤上皮的细胞层次增多，上皮内及上皮下有不同程度的急性、慢性炎细胞浸涧；上皮下有时可见胆固醇肉芽肿、死骨与新骨形成、腺体化生等病理改变。

Etiologically, the commom cancerogens include: lowered power of resistance, weakened functions of spleen and stomach, emotional disturbance such as grief, worry and anger, long term mechanical and inflammatory irritation, granuloma caused by the accumulation of schistosome ova, malignant change of polyp from chronic adenoma, chronic ulcer and anal fistula.

根据病因学，普通致癌物包括：低功率电阻，脾胃功能减弱，情绪困扰如悲伤、焦虑和愤怒，长期力学和炎症刺激，血吸虫卵积聚引起的肉芽肿，慢性腺瘤中息肉的恶性变化，慢性溃疡和肛瘘。

Results Of the 52 specimens, 38 were located in the ciliary body (73.1%), and 14 lesions involved the iris (26.9%). According to the results of histogenetic classification, the tumors of ciliary sensory epithelium were ranked the first place (20 cases, 38.5%) while malignant melanoma, the second one (14 cases, 26.9%) followed by melanocytoma (9 cases, 17.3%) and granulomatous lesions (5 cases, 9.6%).

结果 52例组织标本按解剖部位分类：位于睫状体病变38例（73.1%），原发于睫状体累及虹膜组织14例（26.9%）；按组织来源分类：占第1位者为睫状体神经上皮来源的肿瘤20例（38.5%），第2位者为恶性黑色素瘤14例（26.9%），第3和第4位者分别为黑色素细胞瘤9例（17.3%）和肉芽肿性炎性病变5例（9.6%）。

Results High dense renal cyst is usually homogeneous hypoechogenicity on sonograms and homogeneous high/iso attenuation on CT images and color doppler is helpful in diagnosing.Atypical angiomyolipoma usually shows homogeneous high attenuation on unenhanced CT images,homogeneous enhancement on enhanced CT and homogeneous isoechogenicity on sonograms.The CT features of Xanthogranulomatous pyelonephritisinclude multiple,rounded,low density areas with enhancing rings arranged in a hydronephrotic pattern known as bear paw sign.Acute focal bacterial nephritisshows wedge lesion and stripe sign on delayed enhanced CT images.

结果 高密度肾囊肿常表现为B超均匀低回声，CT均质或高密度灶，彩色多普勒超声有助诊断；不典型肾血管肌脂瘤常表现为B超均匀回声，CT平扫均质高密度且均匀强化；黄色肉芽肿性肾盂肾炎的特征是CT示群集的类圆形的低密度区以及环形增强带形成&熊掌征&；急性局限性细菌性肾炎的CT延时增强扫描以及动态观察显示楔形病灶以及条纹征，并随治疗逐渐消退。

The list of possible causes of diabetes insipidus in this case and many others is extensive and includes infection (tuberculous pachymeningitis and Whipple's disease), malignant neoplasms (germ-cell tumor and lymphoma), infiltrative processes (hemochromatosis and amyloidosis), autoimmune diseases (Wegener's granulomatosis, lymphocytic infundibulitis, and sarcoidosis), and histiocytosis (Langerhans'-cell histiocytosis and non-Langerhans'-cell histiocytosis).

这例病例其他许多病例尿崩症的可能病因广泛，包括感染(结核性脑脊髓膜炎和Whipple病)，恶性肿瘤，变性疾病，自身免疫病（Wegener肉芽肿，垂体茎淋巴细胞瘤和粒细胞肉瘤）和组织细胞增生症（Langerhans细胞和非Langerhans细胞组织细胞增生症

Hepatic granulomas most commonly due to sarcoidosis and tuberculosis .

肝肉芽肿多由肉样瘤病及结核病引起。

Results:The lesion of cholesteatoma (8/17) appeared as mass shadows in tympanic sinusand and cavity with low denisty ring around, accompanied with obvious ossicles chain destruction.

结果：胆脂瘤8例表现为中耳腔内团块状影，周围低密度环包绕，听骨明显破坏及中耳窦腔扩大，骨缘硬化。4例肉芽肿多呈片状、条索状或网状，听骨破坏较轻。

I have seen cases of abundant foamy histiocytes accumulation in stomach presented as polyps, simillar to xantholesma in eyelides, it is called xanthomatous gastritis.

我已看过大量泡沫样组织细胞积聚呈息肉改变的病例，相似于眼睑的黄色瘤，这叫做黄色肉芽肿型胃炎。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
