Many investigators have stated that the difficulties of imaging with acoustical energy through the skull result from the marked attenuation of the energy by the skull. In the literature measurements of total attenuation have been confused with those for absorption.Measurements made by us show that absorption by compact bone varies between 2–3 dB cm?1 MHz?1 and, in the low megaHertz region appears to be directly proportional to frequency.It has also between shown that the convoluted inner surface of the ivory bone of the inner table of the skull may degrade the collimation and directionality of the beam by refraction.Cancellous bone, such as is present in the dipole of the skull, greatly attenuates the energy. It is postulated that this largely results from scattering. It is also postulated that the energy propagates through cancellous bone as two components, one in the soft tissues and the other partly in the bony spicules. Observations suggest that attenuation due to scattering much more markedly affects the latter of these components and scatters more greatly the higher frequencies in a pulse of broad bandwidth.The energy in each component has varying propagation paths so that the later cycles in the pulse of each component are subject to increasing interference as a result of the variations in propagation times. The two components moreover may have different propagation times so that interference may occur between the pulses of each component as well.All of these phenomena degrade the collimation, coherence, directionality, beam width, pulse length, frequency and other properties of the ultrasonic energy upon which imaging through the skull depends.The interference effects described above are least for the first cycle in the pulse which usually is not the cycle of highest amplitude. Since, in the free field, most of the energy is concentrated around the beam axis, most of the energy in the field which is deflected from its normal propagation path is deflected away from the beam axis. Thus the directionality of the beam is least degraded in the beam axis. The effects of the skull in degrading the properties of the ultrasonic pulse would therefore be lessened if the amplitude of the first cycle of the pulse and the directionality of its energy could be used for imaging.  相似文献

SUMMARY: Organ transplantation has developed over the past 50 years to reach the sophisticated and integrated clinical service of today through several advances in science. One of the most important of these has been the ability to apply organ preservation protocols to deliver donor organs of high quality, via a network of organ exchange to match the most suitable recipient patient to the best available organ, capable of rapid resumption of life-sustaining function in the recipient patient. This has only been possible by amassing a good understanding of the potential effects of hypoxic injury on donated organs, and how to prevent these by applying organ preservation. This review sets out the history of organ preservation, how applications of hypothermia have become central to the process, and what the current status is for the range of solid organs commonly transplanted. The science of organ preservation is constantly being updated with new knowledge and ideas, and the review also discusses what innovations are coming close to clinical reality to meet the growing demands for high quality organs in transplantation over the next few years.  相似文献

目的加强对家族性噬血细胞性淋巴组织细胞增生症(familially hemophagocytic lymphohistiocytosis,FHL)的认识。方法报道确诊为FHL的新病例1例,结合国内外报道的FHL的病例,对该病的临床特点进行汇总分析。结果FHL2常与PRF1基因突变相关,约20%~40%的患者存在穿孔素基因突变。结论对于有阳性家族史,基因诊断明确,应尽早行化疗或者造血干细胞移植。若无家族史,未发现与继发性HLH相关的原发病因,可考虑行基因筛查以明确是否存在FHL的可能。  相似文献

Burkitt's lymphoma(BL) is an aggressive form of nonHodgkin's B-cell lymphoma with three variants namely endemic, sporadic, and immunodeficiency-associated types. It is endemic in Africa and sporadic in other parts of the world. While the endemic form is widely reported to occur in early childhood and commonly involves the jaw bones, the sporadic form typically presents as an abdominal mass. This presentation reports a rare case of sporadic form of BL clinically manifesting as a generalized gingival enlargement in an immunocompetent adult male which demonstrated an aggressive behavior. The patient reported with a prominent anterior gingival swelling of 6 mo duration which slowly enlarged in size and associated with multiple lymph node involvement. Microscopic examination of the lesion using H, E and immunohistochemical diagnosis confirmed the diagnosis as BL. The patient succumbed to the disease before any therapy could be instituted. Since a wide array of causes can be attributed to gingival enlargements, it is necessary to consider malignancies as one of the important differential diagnosis so as to facilitate the need for appropriate diagnosis and prompt treatment.  相似文献

目的 甲状旁腺功能减退(甲旁减)性心肌病是一种罕见的心脏疾病,为扩张型心肌病中少数可逆转的一种,常被误诊为不明原因或难治性心力衰竭。本文旨在探寻甲旁减性心肌病的规律性特征。方法 检索Pubmed、SinoMed、万方数据库中符合标准的甲旁减性心肌病病例,采用统计分组法对纳入研究的文献进行分析,依据系统综述和meta分析优先报告条目(PRISMA声明)进行报告。结果 在我们筛查出的41例患者中,女性居多(68.29%),平均年龄为45.5岁,各年龄段均有发病。甲旁减性心肌病最常见的病因为特发性甲旁减(78.05%),颈部手术导致的甲旁减性心肌病次之(17.07%)。患者均以心力衰竭就诊,伴不同程度的低钙血症。51%的患者有神经肌肉兴奋性增加的病史,90%的患者左心室射血分数降低。该病误诊漏诊率较高,仅36%的患者于入院后即明确诊断为甲旁减性心肌病。低血钙的纠正是治疗的关键,90%的患者心脏功能在血钙浓度正常化后恢复至正常。结论 对所有不明原因或难治性心力衰竭患者都应警惕甲旁减性心肌病的可能。  相似文献

目的 探讨术前单核细胞与高密度脂蛋白比值(monocyte to high density lipoprotein cholesterol ratio, MHR)与经皮冠状动脉介入(percutaneous coronary intervention , PCI)治疗后发生造影剂肾病(contrast induced nephropathy, CIN)的相关性,为CIN的发生寻找其他可能的危险因素,为及早筛选CIN高危人群提供新的方向。方法 回顾性分析5P试验入选的我院心内一科行经皮冠状动脉介入治疗术的冠心病患者1 087例,根据在PCI术后是否发生造影剂肾病分为CIN组和非CIN组,研究CIN的相关危险因素,分析MHR与造影剂肾病的相关性,应用Logistic回归分析查看MHR是否为CIN发病的高危因素。结果 CIN组共57例,非CIN组1 030例。两组在高脂血症、BMI、左心室射血分数(LVEF)、术前尿酸及术前C 反应蛋白水平等方面比较差异有统计学意义(P<0.05)。 Logistic回归分析显示LVEF及糖尿病与造影剂肾病的发生相关。结论 同以往研究结果不同,MHR并不能作为CIN的危险因素,但LVEF对于CIN可能具有更高的预测价值。  相似文献
