植物神经癫痫52例脑电图分析

报道52倒6个类型植物神经癫痫,重点分析了脑电图的变化,脑电图异常率100％,69.4％的病例出现两侧阵发性4～7Hzθ节律及6和14Hz阳性棘波,提示中线深部有功能紊乱,亦支持丘脑及脑干部有病变。此外蝶骨电极能提高脑电图对本病的阳性诊断率,值得采用。本文证明脑电图对植物神经性癫痫与非癫痫的鉴别诊断,具有肯定的价值。     

Isolation and characterization of marine luminous bacteria from shallow coastal waters of Taiwan.

BACKGROUND AND PURPOSE: Marine luminous bacteria were isolated and identified from samples in shallow coastal waters of Taiwan during the relatively warm seasons. METHODS: Identification of the luminous isolates was performed based on differences of phenotypic and genotypic characteristics together with data from phylogenetic analysis. RESULTS: Twenty seven strains of marine luminous bacteria were isolated. They were divided into five types based on differences of phenotypic characteristics. However, they could be clustered into only two genotypes according to the analysis of restriction patterns of polymerase chain reaction-amplified 16S rRNA genes digested with various restriction enzymes. The characterization data together with the 16S rRNA gene-based phylogenetic analysis revealed that the isolates included in phenotype I (seven isolates) could be Photobacterium leiognathi, and those included in phenotypes II-V (twenty isolates) might be classified as Vibrio harveyi. However, phylogeny based on gyrB sequences indicated that phenotypes II-V could be classified into two species, V. harveyi and Vibrio campbellii. CONCLUSION: Culturable luminous bacteria in the shallow coastal waters of Taiwan during the sampling period are dominated by V. harveyi/campbellii and P. leiognathi, and the former species appeared to be more prevalent and numerous than the latter species in general.

Implications of remarriage and stepfamily formation for marriage education*

Couples in remarriages with stepchildren are a significant portion of the marriage population and have unique educational needs regarding aspects of couple functioning within the context of stepfamily development. From a review of the literature, we examine current curricula focused on these couples. Information is offered on implementation issues regarding recruitment, delivery context, facilitator and participant characteristics, and evaluation.

Stargardt病的眼底表现及眼底荧光血管造影特征

目的研究Stargardt病(Stargardts disease,STGD)的眼底表现和眼底荧光血管造影(fundus fluorescein angiography,FFA)的特征.方法对27例54眼STGD患者进行视力、眼底及FFA检查.结果STGD患者的视力在0.02～0.10者46眼,占85.2%.眼底检查黄斑部均有横径为1.5～3.0 PD大小、呈青灰色并有金箔样反光的横椭圆形萎缩灶,其中15例30眼伴有眼底黄色斑点,占55.6%.FFA检查黄斑部病变为透见荧光,其中8例16眼呈"牛眼"状;22例44眼呈暗脉络膜背景,占81.5%.结论FFA检查在STGD的诊断中极为重要,在病程的不同阶段可有不同FFA表现.
