锰超氧化物岐化酶模型配合物的研究

为探索天然超氧化物岐化酶（ＳＯＤ）岐化超氧离子的机理，及用于临床的可能性，我们合成了乳酸、柠檬酸和酒石酸的锰（Ⅱ）配合物作为Ｍｎ－ＳＯＤ的模拟物，用光照法测定了它们的活性，得到了有意义的结果：锰配合物作为Ｍｎ－ＳＯＤ的模拟物，有肯定的活性，其中以乳酸锰配合物活性最高。     

The clinical significance of red cell immune adherence function in patients with pulmonary tuberculosis and silicotuberculosis]

In our study, we observed that (1) High RCIA were discovered in these two groups. (2) In the group of pulmonary tuberculosis, the C3b receptor activities remained no change after antituberculous therapy, but the amounts of immune complexes bearing on RBC decreased. In the patients with the high RCIA, CIC was discharged rapidly and the lesions of tissue produced by CIC were prevented. In the patients with silicotuberculosis, both silica and tuberculous bacilli may act as immune adjuvant and enhance the hypersensitivity. So the C3b receptor activities were higher in silicotuberculosis patients.     

烤瓷贴面修复20例临床观察

目的评价烤瓷贴面的修复效果。方法选择20例患者制作烤瓷贴面92个。复诊时对烤瓷贴面的边缘适合性,边缘着色及颜色进行评价;同时采用牙龈出血指数和菌斑指数评价治疗前后的牙周状况。观察时间为12～18个月。结果5颗牙烤瓷贴面失败,成功率为95.7%;烤瓷贴面治疗前后牙龈出血指数无显著性差异(P>0.05),治疗后菌斑指数降低(P<0.01)。结论烤瓷贴面具有较好的治疗效果。     

Hb Las Palmas or alpha 2 beta 2(49)(CD8)Ser----Phe, a mildly unstable hemoglobin variant

A new hemoglobin variant with a Ser----Phe substitution at position beta 49(CD8) was discovered in two members of a family living in the Canary Islands, Spain. Detection was by polyacrylamide gel electrophoresis and by reversed phase high performance liquid chromatography. The variant, which constituted 43% and 45%, respectively, in the two heterozygotes, was slightly unstable. Its presence did not affect hematological values though there was a mild reticulocytosis.     

高原老年人和红细胞增多症病人返回平原后记忆功能的“脱适应”研究

15例离退休健康男性老人和9例红细胞增多症男性病人返回平原后,记忆功能改变的特点:①两组受试者除5例成绩下降外,苏州记忆成绩高于西宁成绩(p<0.01)。②记忆成绩降低现象存在于20%左右的人中。③高原缺氧和返平原脱适应均主要影响短时记忆。     

HLA class II genes in Graves' disease.

Inheritance of Graves' disease has been linked to the HA-DR3 gene product which may function in some specific way in antigen presentation. To determine whether the first extracellular domain of this protein, which is specifically involved in antigen presentation, has the same sequence in patients with Graves' disease and in normal individuals, we have amplified the second exon using the polymerase chain reaction, and then cloned and sequenced the DNA segment. In eight subjects with Graves' disease, sequences identical to prototypic reported sequence for DRB1*0301 were recovered, and in two individuals sequences varied by a few nucleotides, leading to 1-3 amino acid substitutions which did not occur in a pattern. Sequences identical to the prototypic sequence known as DRB3*0101, also previously known as DRw52, were also recovered. Thus the HLA-DRB1 and B3 genes present in patients with autoimmune disease appear to be the same as those present in the general population. These observations indicate that a unique allele is not present in patients with autoimmune disease, but rather that the normal DR3 allele itself, in a manner yet to be described, increases the probability of developing autoimmune thyroid disease.     

甲状腺肿瘤X线造影与超声检查对比分析

本文报告了经手术病理证实的53例甲状腺肿瘤,均作了甲状腺造影和B超检查.通过比较分析,我们认为造影对确定肿瘤的良、恶性以及延伸到胸骨后的异位甲状腺肿瘤有其优越性,是一项有效的检查方法;超声则能准确地判断肿瘤的囊、实性,适合碘过敏患者的检查.两种检查各有特点,配合使用有利于对甲状腺肿瘤的诊断和治疗.     

柠檬月亮

明月的公司叫MOONRIVER，不知道的人总以为那些带着粗糙划痕的石壁圈住的是一个咖啡厅，其实不是。屋子里只有素色的窗帘和柔软的沙发，茶几上没有咖啡，但永远放着新鲜的柠檬水，明月接待客 从不做笔录，优质的采访机放在不被注意的地方，工作的时候，电源信号灯轻轻闪烁，明明灭灭。
