The DICOM standard

The DICOM Standard for network communication has been approved by ACR and NEMA in October 1993. The ACC has joined the effort in 1992 and drives the extension of DICOM for Media Interchange with a focus on defining a digital recording standard for communication between catheterisation laboratories. This is a necessary foundation towards cinefilm replacement. DICOM networking is being adopted as a European Standard called MEDICOM and the increasing interest of the ESC is likely to result in the adoption of DICOM Media Storage and interchange as an extension of MEDICOM in 1995. This represents a major breakthrough in the communication of medical images in electronic form. DICOM has been designed to offer an integrated approach to the increasing use of high speed computer networks in health care as well as larger and higher throughput storage media. This article focuses on the network communication as well as introduces the extension of DICOM for Media interchange which has been approved early 1995.

Alternatives to standard cataract surgery

Two alternatives to standard cataract surgery have been developed which have distinct benefits in selected patients. Phacoemulsification, which requires only a small incision and little recovery time, is particularly suited to young patients. Elderly patients, who often cannot wear aphakic spectacles or contact lenses, may benefit from intraocular lens implantation.     

清喉消炎颗粒质量标准研究

目的建立清喉消炎颗粒的质量标准。方法采用薄层色谱（TLC）法对处方中的板蓝根、地胆草、甘草进行鉴别,采用高效液相色谱（HPLC）法对甘草酸胺进行含量测定。结果TLC图谱中能清晰鉴别板蓝根、地胆草、甘草;甘草酸胺浓度在0．495-1．73μg范围内与峰面积积分值呈良好的线性关系（r=0．9997）,平均回收率为97．4％,RSD=1．9％（n=6）。结论所建标准可用于清喉消炎颗粒的质量控制。
