近3年来,用制备的胎骨充填良性骨肿瘤及病样病变术后骨缺损,经观察10例效果良好。胎骨因其自身组织学和生理学特点,具有抗原性小、诱导成骨活性高,利于“爬行各代”等优点。而且来源丰富、采制简单、储存容易、费用低度,是一种良好的植骨材料,特别适于儿童及年老体弱患者自身取骨困难的骨缺损植骨需要。但其为异体骨,有一定免疫原性,抗支撑强度略差,应注意严格无菌操作、消除免疫原性、配合使用内、外固定等措施。 相似文献

The most spectacular contribution from the nordic countries to intellectual disability policy is probably the idea of normalization, but it is not the simplistic notion that can be inferred from international debate. Its major significance may have been to act as an inspiring catchword for the important trend away from institutions Into integrated living. However, it is more fully understood when seen in the concrete context where It has successively developed, and been critically analysed and tested in operation. Scandinavian sociologists and psychologists—as well as politicians—were also among the first to use the concept of quality of life for analysis of social policy, including intellectual disability. The primary medium for implementation has been legislation, where the dominant difficulty is to find a balance between security and freedom, protection and self-determination. Through this process, the role of social engineering in the welfare state, based on humanistic ideas of solidarity, can be followed into today's emphasis on individual influence and participation. 相似文献

Immunocytochemically detectable MT and p53 have been found more commonly in comedo DCIS of the breast with high-grade cytology.
The aim of this study is to confirm these findings and to investigate the relationship between MT and p53 in a single large
series of cases of DCIS of the breast. To this end, 127 cases of DCIS were classified histologically according to architecture,
cytonuclear differentiation (grade), presence and extent of intraduct necrosis, and using the Van Nuys system. Sections were
immunostained for p53 and MT (E9) using established techniques, and the extent and intensity of staining were assessed semi-quantitively.
The results confirmed that there was generally more MT and p53 positivity in poorly differentiated (grade 3) DCIS with extensive
necrosis and that MT expression was greater in grade 2 lesions than p53 expression. However, overall there was no statistically
significant correlation between p53 and MT staining. The results indicate that MT and p53 overexpression may arise from independent
mechanisms in early breast neoplasia.

腹腔镜卵巢穿刺内凝治疗多囊卵巢不孕症的临床研究 总被引:2,自引:0,他引:2
目的探讨腹腔镜卵巢穿刺内凝对多囊卵巢不孕症的治疗价值。方法151例腹腔镜卵巢穿刺内凝术(实验组)和151例开腹卵巢楔切术(对照组)治疗多囊卵巢不孕症配对对比研究。结果实验组的手术时间33.1±7.2min,术中失血15.6±4.7ml,总排卵率92.05%,总妊娠率49.67%,均优于对照组(P<0.01);术后雄激素、LH/FSH下降幅度小于对照组(P<0.01)。随时间推移,两组术后排卵巢、妊娠率均有下降倾向,而术后雄激素、LH/FSH则有逐渐回升的倾向。结论腹腔镜卵巢穿刺内凝术对多囊卵巢不孕症有较好的治疗效果 相似文献

Rh血型不合新生儿溶血病检测方法及应用 总被引:3,自引:0,他引:3
产前检测Rh,D因子及抗人球蛋白(coombs)试验是必要的。测定Rh,D因子及抗D滴度使用木瓜酶方法。通过对11261例孕妇常规检查Rh,D因子,发现D阴性74例。Rh,D阴性妇女占6.5‰。22例Rh,D阴性的孕妇所分娩的新生儿均为Rh,D阳性。其中2例孕妇血清抗D滴度为1∶32,病情严重,宫内输血无效,胎死宫内。初产妇13例,占59%。活产20例,存活率90%。Rh因子及抗人球蛋白试验方法简便、易行,一般医院均可进行。对有流产史、输血史的孕妇检查Rh因子是十分必要的。在有条件的医院,对Rh,D阴性的产妇分娩Rh,D阳性的新生儿之后,产妇应预防性注射抗D免疫球蛋白 相似文献

The authors present three cases of vein of Galen aneurysmal malformations (VGAMs) diagnosed in infancy and submitted by the referring teams for stereotactic radiosurgery as the initial therapy (therapeutic doses ranging between 20–25 Gy and 40–50 Gy to the peak dose). After the conventional follow-up of 18–24 months, no change could be detected in the angioarchitecture of the lesions. All three cases were then referred for endovascular treatment and underwent embolization by the transarterial route using liquid adhesives (N-butyl cyanoacrylate). This resulted in complete anatomical exclusion of the lesion. Regardless of the theoretical efficiency of radiosurgery in the management of brain arteriovenous malformations, the present authors believe that transarterial embolization remains the treatment of choice in VGAMs. It offers a high rate of morphological cure and the best chances for normal neurocognitive development. The time required by radiosurgery to achieve a significant result is too long for developing and maturing brain and may not prevent the negative effects of the lesion, mainly in regard to hemo- and hydrodynamic disorders (atrophy, subcortical calcifications, etc.) created by the VGAM, thus leading to irreversible mental retardation. 相似文献

The role of proteolytic enzymes in the hCG-induced increase in testicular vasopermeability and neutrophil extravasation was studied using protease inhibitors. An intra-testicular injection of hCG together with incubation medium conditioned by polymorphonuclear leucocytes (PMNs) caused a significant increase in vasopermeability and a coincident extravasation of PMN's from the postcapillary venules in the rat testis. When p-aminobenzamidine, a serine protease inhibitor which inhibits urokinase-type plasminogen activator, was administered together with hCG in the incubation medium, both the permeability increase and PMN extravasation were prevented. Aprotinin, another serine protease inhibitor, and Eglin C, a specific neutrophil elastase and cathepsin G inhibitor were, however, without effect. None of these inhibitors caused any non-specific vascular effects in the testis at the concentrations used. These results support the concept that the hCG-induced increase in vasopermeability in the rat testis is related to extravasation of PMNs and suggest that urokinase-type plasminogen activator is involved in migration of these cells through the postcapillary venular walls. 相似文献
