Results: Mel specific binding sites were det ermined in 16 kinds of human embryonic tissue and this binding could be inhibit ed by GTPγS, supporting the theory that MR is coupled to inhibitory G-proteins system.

结果：经饱和分析、动力学分析及特异性分析证明人胚胎心、肝、肾及甲状腺等16种组织均存在Mel特异结合位点，亚细胞分布研究表明这些组织中以细胞核及线粒体MR含量最高；GTPγS能够抑制Mel与其受体的结合，使MR的结合容量或亲和力降低。

Objective To study the MR signal intensity of breast cancer and fibroadenoma so as to explore the value of MR signal intensity in diagnosis of benign and malignant breast neoplasms.

A series of technologies were established and applied to this study, which include MR electron microscopy by using mannosylated albumin-colloidal gold (DMA-G10) as probe, modified CBB method for acrosome reaction detecting, improved model of human acrosome reaction induced by mZPS (solubilized mouse zona pellucida), in vitro heterogenic fertilization and affinity cytochemistry, preparation and purification of proteins.

本研究建立了MR的电子显微镜探针——甘露糖基化白蛋白-胶体金及其检测法、移植建立了人精子顶体反应的CBB检测法、改良了mZPS诱导人精子顶体反应实验模型，同时运用体外获能、异种体外受精、亲和细胞化学、蛋白质提纯制备等技术与实验模型，对人精子MR的表达、定位和生理功能加以探讨。

Results:Conventional MR showed infraspinatus abnormalities were four cases,Mrarthrography showed infraspinatus abnormalities were seven cases.

Criteria for diagnosis:(1) soft-tissue swelling: intermuscular space swelling demonstrate ill-defined intermuscular planes on CT, and string-like intermediate signal intensity on MR T1-weighted images and high signal intensity on MR T2-weighted images.

皮下组织肿胀表现为自身厚度增加，CT可见皮下脂肪内细网状或条索状软组织样密度，MR T1WI示高信号的脂肪内细网状、斑片状或条索状中等信号，在脂肪抑制T2WI呈高信号，边界不清。

When MR imaging shows thickening and enhancement of the pituitary stalk and associated leptomeningeal disease as in this case, sarcoidosis is a very strong possibility, along with meningitis, particularly fungal.

结节病为一种不明原因的炎性病变，可以影像多个系统，包括中枢神经系统，女性多见，大于10：1，黑人比白人更多见，15%病人累及中枢神经系统，5%有神经症状，脑神经功能障碍和尿崩症是最常见的神经系统结节病的临床表现，MR改变包括脑膜增厚及强化，孤立性肿块或多发性小，散在的脑膜或实质病变，此例病例中MR图像出现增厚强化的垂体蒂伴有软脑膜病变，强烈提示结节病，伴随脑膜炎尤其是真菌性，通常T2表现为低信号，虽然这些也能够在霉菌病/淋巴瘤/脑膜瘤中看到。

Mr. Rosen is monochromic, whereas Mr.

Rosen具有单一时间导向，Mr。
