BACKGROUND: Platelet aggregation and thrombus formation within the coronary artery are major factors in acute coronary syndrome. The platelet glycoproteinIIb/IIIa receptor is a pivotal mediator of platelet aggregation. Recently there have been reports that the genetic polymorphism of GPIIIa is an inherited risk factor for coronary artery thrombosis. This study investigated the relation between the Pl(A) polymorphism and coronary artery disease in Korean patients. METHODS: One hundred patients with acute myocardial infarction and unstable angina were enrolled. Coronary angiogram was performed in eighty-one cases. Genomic DNA from peripheral blood was amplified by polymerase chain reaction. Allele-specific restriction digestion was used to determine the Pl(A) genotype. RESULTS AND CONCLUSIONS: The prevalence of Pl(A2) genotype was zero percent in our study group. All patients had the Pl(A1/A1) genotype. These results suggest that Pl(A) genetic polymorphism of GPIIIa is not an inherited risk factor for coronary artery diseases in Koreans.

Fusional amplitudes can be measured using various clinical techniques and targets. But the vergence ranges are different according to the used instruments and the environmental conditions. Currently, measurement with the prism is usually llsed but this method have wide vardabele ranges by the used targets and environmental settings. The authors measured the vertical and horizontal fusional amplitudes of 135 normal Korean men with rotary prism in a well-lit office and compared the group using dim light targer with the group using small letter target. In the group using dim light target, true far convergence value was 14.67 +/- 6.24 delta, true far divergence was 6.64 +/- 3.48 delta, true near convergence was 24.96 +/- 7. 33 delta, true near divergence was 11.05 +/- 5.13delta, far vertical vergence was 2.93 +/-0.95 delta, and near vertical vergence was 3.40 +/- 1.15 delta, There was no statistical differences among are groups(p>0.05), and between the groups using small letter target and dim light target in true near and far convergence amplitudes (p>0.05). This study shows that the method using dim light target is simple and valuable method in measuring the fusional vergences.

There is increasing need for network connecting personal computers(PC) together. Thus Local Area Network(LAN) emerged, which was designed to allow multiple computers to access and share multiple files and programs and expensive peripheral devices and to communicate with each user. We built PC-LAN in our department that consisted of 1) hardware-9 sets of personal computers(IBM compatible 80386 DX, 1 set:80286 AT, 8sets) and cables and network interface cards (Ethernet compatible, 16bits) that connected PC and peripheral devices 2) software - network operating system and database management system. We managed this network for 6 months. The benefits of PC-LAN were 1) multiuser (share multiple files and programs, peripheral devices) 2) real time data processing 3) excellent expandibility and flexibility, compatibility, easy connectivity 4) single cable for networking ) rapid data transmission 6) simple and easy installation and management 7) using conventional PC's software running under DOS(Disk Operating System) without transformation 8) low networking cost. In conclusion, PC-LAN provides an easier and more effective way to manage multiuser database system needed at hospital departments instead of more expensive and complex network of minicomputer or mainframe.
