The purpose of this study is to evaluate the color differences that can exist between differnet brands of dentin porcelain having identical shade designations. The instrumental colorimetric technique was used to determine these differences. The three brands of dentin porcelain used were Vita VMK-68, Shofu Vintage, and Ceramco II. The three shades selected were the Vita Lumin shades A2, B2, and C2. The color difference values were compared with each other using L*, a*, b*, three variables of the CIELAB color system, and E. The results of this study were as follows: 1. Corresponding shades of different brands of dentin porcelain produced different L*, a*, b* values. 2. The greatest E value in corresponding shade was found to exist between Ceramco II and Shofu Vintage, followed by between Vita VMK-68 and Ceramco II, and then between Vita VMK-68 and Shofu Vintage. 3. The E values in shade C2 were mainly influenced by L* value ; however none of L*, a*, b* values had greater influence on E values than the others in shade A2, B2. 4. Shofu Vintage had the highest b* value, followed by Vita VMK-68, and then Ceramco II.

The Marfan syndrome, a rare disease causing a marked decrease in life expectancy by involving the skeletal, ocular, and cardiovascular systems, is known as a connective tissue disorder that is inherited autosomal dominant. The cardiovascular complications directly related to the cause of death are associated with more than 90% of the Marfan syndrome. Aortic aneurysm with rupture could occur because of dilatation of aorta due to defect of media. Aortic and mitral insufficiency, mitral valve prolapse, bacterial endocarditis, arrhythmia, and aneurysm of interatrial septum are also frequently observed. A few literatures were reported domestically pertaining to the Marfan syndrome thus far, and there are increased discoveries of cardiovascular complications of the syndrome with the application of echocardiogram. However, the Marfan syndrome with LA myxoma has never been reported both domestically and internationally(INDEX MEDICUS, 1966-1989). Therefore we hereby report a case of the Marfan syndrome with LA myxoma from the observation of a patient who was admitted to Eulji General Hospital at Taejeon i August of 1989.

Unilateral absence of the articular process at a lumbar vertebra is a rare anomaly. The etiology of the congenital absence of articular process is not precisely determined yet, but it was explained as some of the possible embryologic bases. Absence of the articular process at the level of L5-Sl have been reported a few, but anomaly above L4 is rare. We are reporting a case of absence of articular process at the level of the 4th lumbar vertebra.

Joubert syndrome is the very rare autosomal recessive disorder which is including agenesis of cerebellar vermis, respiratory discomfort, ocular motor apraxia, hereditary retinal dystrophy, ataxia and developmental retardation. To diagnose, the findings of electroretinography and visual evoked potential study can be useful and hypoplasia of cerebellar vermis in brain MRI can make certain diagnosis. We found ocular motor apraxia without head thrusts in 4-month little baby can't even control his head and neck, and then his electroretinography and visual evoked potential study was normal and there was agenesis of cerebellar vermis by MRI finding. So he was diagnosed as Joubert syndrome with ocular motor apraxia. Agenesis of cerebellar vermis is considered to be one of the causes of oculomotor apraxia, and the clinical presentation varies with the age and motor development of the child. So, we describe this case with a brief review of the literatures related to this disease.
