查询词典 Cortex

Cases of parosteal osteosarcoma on tibia showed bony tumor, which basilar part accreted surface of bone on X-ray, and vicinity cortical bone hyperplasia and harden, soft tissue mass with focal or cauliflower-like high density tumor bone in it. A lucent zone between the cortex and tumor bone was noticed in 1 case.

Abstract］ objective to discuss radiological findings of parosteal osteosarcoma on emphasis combined with clinical pathology and literature.methods 4 cases of parosteal osteosarcoma proved by operation and pathology were analyzed retrospectively.results female was 3 cases,male was 1 case,average age was 30.5 years old,these tumors were arised on posterior border of distal femur and popliteal cavity,presented as lobular dense ossified mass,defined lesion.one case had villose margin.a thin narrow lucent zone separated the mass from the cortex at two cases.one case underwent angiography,there was no malignant feature.conclusion parosteal osteosarcoma may be divided into low-grade type and high-grade type.radiological manifestations of early stage possess character,early diagnosis conduces to establish rational treating plan and evaluate prognosis.

目的 结合临床病理学特征和文献资料，重点讨论皮质旁骨肉瘤的x线特征。方法收集经手术、病理证实的皮质旁骨肉瘤病例4例，对其进行回顾性分析。结果 4例患者女3例，男1例，平均年龄30.5岁，肿瘤均发生于股骨远端后侧和腘窝处，表现为分叶状致密骨化肿块，边界清晰，其中1例边缘呈绒毛状改变，2例有细窄透亮带与骨皮质相隔，1例行血管造影，未见血管池等恶性征象。结论皮质旁骨肉瘤分为低度恶性和高度恶性两种，早期影像学表现有特征性，早期诊断有助于制订相应的治疗方案和评估预后。

Following small injections into the caudal part of the insular cortex, the retrogradely labeled neurons were mainlyseen in the parvicellular ventroposterior lateral nucleus of the thalamus, thecentral lateralsubdivision of the PBN, theouter part of the external medial subdivision of the PBN, and the contralateral PBme.

将HRP注入岛皮质首部，标记细胞见于VPMpc和PBN：VPMpc的标记细胞多位于其内侧部，大小为10-15u，以梭形细胞为主，还有圆形和三角形细胞，标记的纤维末稍较少见；PBN的标记细胞主要位于PBl腹侧区和PBm中央区，即PBN腰区，个别细胞散在于小脑上脚内，有少量标记纤维末稍。在PBN其它亚核很少见到标记成分。

Following small injections into the rostral part (namely the dysgranularfield, DI) of the insulpr cortex, retrogradely labeled neuronswere primarily in the parvicellular ventroposterior medial nucleus of the thalamus, the "waist" area of the PBN.

标记细胞有卵圆形、梭形和不规则形，大小平均15u。将HRP注入岛皮质后都，标记细胞见于VPLpc和PBN：VPLpc的标记细胞多位于其中间部，密度较低，以圆形卵圆形细胞为主，梭形和三角形细胞较少见。

Hewever the caspase-3 expression was still very high in cortex. Conclusion: In KA model the hippocampus amygdala plays a key role in epilepsy. Therefore it provides a mimic optimal conditions for human temporal lobe epilepsy study. Its an effective method of studying the development, change and pathopoiesis of epilepsy. There is a close relationship between NPY and epilepsy. The regulation of NPY via VPA may be one of the antiepilepsy mechanism of mechanism of VPA. Moreover NGF can enhance the caspase-3 expression. Excito-amino acid can aggravate the apoptosis, which may be one of the reason for intractability of epilepsy.

KA模型因其海马杏仁核在癫痈中起核心作用，故具有模拟人类颗叶癫痈的理想条件，是研究癫痈发展变化、致痈机理的有效工具，NPY与癫病有着密切的联系，VPA调节NPY有可能是其抗癫痈机理之一，而NGF对caspase一3表达有促进作用，兴奋性氨基酸可造成细胞凋亡的增加，而凋亡细胞的增多有可能是癫痈久治不愈的原因之一。

It typically presents as a pedunculated or sessile mass, slightly hypo- or isointense to cortex on T1 and generally slightly bright on T2, without contrast enhancement and stable over time.

典型表现为有蒂或无蒂的肿块，T1序列上表现为稍低或等信号，T2为稍高信号，无强化，MRS表现为低NAA，正常到轻度升高的胆碱峰和高肌醇。

Suis was found in all identifiable crypt areas; SS2 also appeard in marginal zone and periarterial lymphoid sheath of spleen, hepatic sinusoid of liver, interstitium of lung; presence of SS2 was at the cortex where histopathological lesions and expression of inflammatory mediators were observed.

实验表明，SS2主要定殖于扁桃体的隐窝附近；在脾的边缘区和动脉周围淋巴鞘附近、淋巴结的生发中心和皮质内、肝血窦、肺间质和肾小体中均可见菌体状荧光颗粒；在脑组织中发生脑膜炎的区域，如皮层等可检出细菌。

The results were as follows: Compared with control group, the weight and the relative weight of thymuses, bursas of Fabricius and spleens of experiment group increased significantly(P＜0.05) or extremely significantly(P＜0.01). In experiment group, the cortex of thymic lobule, bursa nodule and Periarterial Lymphatic Sheaths thicken obviously; the volume of bursa nodule, splenic nodule and ellipsoid augmented, and the germinal center of splenic nodule were obvious; the thymic corpuscle increased; the plica of bursas of Fabricius developed well and the degenerating of it retarded.

结果表明：试验组鸡胸腺、腔上囊、脾的重量和器官指数均高于对照组，差异显著(P＜0.05)或极显著(P＜0.01)；试验组的胸腺小叶皮质增厚，胸腺小体增多；腔上囊皱襞发达，腔上囊小结体积大，皮质较厚，退化延缓；脾的动脉周围淋巴鞘增厚，脾小结体积大，生发中心明显，椭球增大。

Regional cortical blood flow of cortex irradiated fell dramatically in the model of focal brain ischemia induced photochemically, to the level about 18% by control during ischemia 6h. But there were no changes in the unirradiated side.
