REM sleep behavior disorder and vocal cord paralysis in Machado-Joseph disease.

We evaluated the occurrence of REM sleep behaviour disorder (RBD) and vocal cord abductor paralysis (VCAP) in a group of 9 Machado-Joseph disease (MJD) patients. RBD was diagnosed by clinical history plus audiovisual polysomnography in 4 men and 1 woman (55%). While dreaming, 4 fell out of the bed and the other injured his arms. Laryngoscopy detected bilateral VCAP in 1 patient with stridor who required emergency tracheotomy, and partial vocal cord abductor restriction in 2. RBD and VCAP are two potentially injurious conditions that should be considered part of the clinical spectrum of MJD.     

胰岛素增敏剂曲格列酮对人卵巢颗粒细胞芳香化酶活性的抑制作用

为探讨曲格列酮(troglitazone,TGZ)对人卵巢颗粒细胞芳香化酶(P450arom)活性的调节作用，以不同剂量的TGZ和(或)维甲酸类X受体(RXR)激动剂(LG100268，LG)处理来源于体外受精患者的卵巢颗粒细胞24h，然后测定细胞的芳香化酶活性和P450arom mRNA水平。结果发现，TGZ处理颗粒细胞24h可引起剂量依赖性的芳香化酶活性下降；LG单独作用可以抑制芳香化酶活性，但与TGZ合用对芳香化酶的抑制作用更明显；RT-PCR结果显示，随着芳香化酶活性的下降，P450arom mRNA表达水平也降低。表明TGZ可能是通过过氧化物酶体增殖物激活受体γ(PPARγ)：RXR异二聚体组成的核受体系统直接抑制卵巢颗粒细胞芳香化酶活性。     

南京地区23例成人非何杰金淋巴瘤免疫病理分析

应用了A、B、C法7种单克隆抗体进行免疫组化染色,检测南京地区23例成人非何杰金淋巴瘤活检标本,结果示9例T系淋巴瘤,8例B系淋巴廇,非T非B及未定型淋巴瘤各3例。病理组织学表现与免疫表型符合率B系达80％,T系达60％。故根据形态学表现估测免疫表型是可行的。经HTLV抗体血清检测,仅1例多形细胞性T淋巴瘤患者阳性。     

Use of electric stimulation for activating the process of bone consolidation

A method of electrostimulation aimed at activation of bone adhesion processes was developed and introduced into practice at the Latvian Research Institute of Traumatology and Orthopedics on the basis of data on bone bioelectric activity. The method was used in complex with external fixation of the fracture by Kalnbers' apparatus. The phase pattern of callus formation necessitated the employment of the appropriate potential of direct current. Cyclic potentials similar to piezopotentials of a normal bone in cyclic physiological load were used in the phase of functional reorganization. Positive results were achieved in 88.4% of 79 patients.
