Vessel enhancement filtering in three-dimensional MR angiograms using long-range signal correlation

Small vessels in three-dimensional MR angiograms have low visibility in maximum-intensity projection images because of their low contrast. In a previous study, we had two nonlinear filters that appeared to give significant improvement in small vessel detail. In this paper, we report on a generalization of this filter that allows a more general modeling of the vessels and a more complete suppression of background. One implementation of the general filter gave a vessel mean contrast-to-noise ratio that is 2.52 and 3.51 times higher than the vessel mean contrast-to-noise ratio obtained using our previously reported maximum-minimum (max-min) filter and cross- section filter, respectively.     

米非司酮配伍米索前列醇终止早孕用药方法的探讨

作者对１２０例妊娠４９ｄ以内的孕妇采用４种不同的服药方法进行药物流产，其中使用第３、４种用药方法的孕妇均于加用米索前列醇后８ｈ内排出孕囊，且２ｈ内排出率明显增加，与常规用药方法比较有显著性差异（Ｐ＜０．０１），同时对用药机理作了讨论。     

胃粘膜肠上皮化生与胃癌关系的粘液组织化学和免疫组织化学研究

应用ＡＢ（ｐＨ１．０）ＫＯＨ／ＰＡＳ粘液组织化学和ＡＢＣ法凝集素标记免疫组织化学方法对１９０例胃粘膜标本进行观察。结果表明，结肠不完全型肠上皮化生多见于肠型癌及其癌旁组织。在形态学和功能上，显示出一定程度的分化不成熟。两型肠化在弥漫型癌中无显著差异。５种凝集素受体含量和分布的差异与胃癌的组织学类型和分化程度有关，凝集素肠化分型和组织学类型的关系与粘液组化染色基本相符。我们认为不完全型肠化与肠型胃癌的发生关系密切，而完全型肠化可能与弥漫型胃癌有关。应用ＡＢ／ＫＯＨ／ＰＡＳ染色进行肠化分型和凝集素标记，对于癌前病变的检测和癌的早期诊断都具有一定价值。

溶血磷脂胆硷对缺血性心室肌电生理的影响

用台氏液加溶血磷脂胆硷（ＬＰＣ）３ｘｌ０－４灌流离体绵羊心室小梁肌，其０期去极化最大速率（Ｖｍａｘ）、静息电位（ＲＰ）、动作电位幅值（ＡＰＡ）、动作电位复极达ＡＰＡ５０％和９０％的时程ＡＰＤ５０、ＡＰＤ９０分别下降３９．８％、１０．４％、１４．５％、２１．３％和１４．８％；用“模拟缺血溶液”加ＬＰＣ３×ＩＯ－４灌流，其Ｖｍａｘ、ＲＰ、ＡＰＡ、ＡＰＤｓ０和ＡＰＤ９０分别下降７８％、２２．７％、２６％、３５．４％和２１％；实验中对“模拟缺血溶液”中各种成分对ＬＰＣ效应的影响进行分析，发现主要的因素是酸中毒。结果表明：ＬＰＣ是心肌缺血中心律失常的重要因素之一，缺血诱导的酸中毒更加重了ＬＰＣ对心肌细胞的毒性作用。

良、恶性肿瘤患者血清铜蓝蛋白放射免疫测定及其临床意义探讨

本文用放射免疫分析法测定了１６８例良、恶性肿瘤患者的空腹血清铜蓝蛋白含量，结果显示良性肿瘤患者高于正常对照组（Ｐ＜０．０５），恶性肿瘤患者显著高于正常对照组和良性肿瘤患者（Ｐ＜０．０１）．提示用放射免疫分析法测定血清铜蓝蛋白可作为恶性肿瘤的一项重要辅助诊断指标，有助于良、恶性肿瘤的诊断与鉴别诊断。     

Primate endocrine function after pancreatico-duodenal-splenic allotransplantation

In this study the endocrine function following intraperitoneal hetero- and orthotopic pancreatico-duodenal-splenic allotransplantation (PDS) in hemipancreatectomized, non-immune-suppressed chacma baboons was assessed. Significantly reduced K-values and insulin release together with glucose intolerance during IVGTT were observed in hemipancreatectomized recipients (HPS) without grafts. Orthotopic and heterotopic PDS transplantation improved the glucose intolerance of HPS recipients; orthotopically sited grafts rendering the best curves. Normal glucose tolerance was not achieved. Both orthotopic and heterotopic PDS transplantation rendered suboptimal insulin release during IVGTT; heterotopically draining grafts released significantly more insulin than orthotopic grafts. Hyperglucagonaemia during IVGTT was a constant feature in both groups, heterotopic grafts releasing the most glucagon during stimulation. C-peptide release was significantly lower in orthotopic grafts compared to normal animals or heterotopically drained insulin. It is concluded that glucose tolerance was not directly related to insulin or glucagon release in this study as orthotopic grafts rendered near-normal IVGTT curves in the presence of hypoinsulinaemia, hyperglucagonaemia, and reduced C-peptide values. The hormonal response after PDS transplantation was variable and the advantages of portal vs systemic insulin drainage remain to be defined.
