From May, 1978 through Oct., 1979 the effect of Coenzyme Q10 was evaluated on 10 patients with chronic heart failure. The subjects selected for this study consisted of 7 patients with cardiomyopathy and 3 patients with valvular heart disease admitted to Severance Hospital, Yonsei University College of Medicine, All these patients had symptoms and signs of congestive heart failure which was stable for at least one month before starting Coenzyme Q10. Coenzyme Q10 was administered 30mg daily for eight weeks, one hour before meal and in combination with digitalis and/or diuretics. The drug effects were determined by measuring the cardio-thoracic ratio by chest X-ray, the sum of 'S' wave in V1 and 'R' wave in V5 in electrocardiogram, and PEP/LVET (pre-ejection period/left ventricular ejection time) by simultaneous tracings of carotid pulse and phonocardiogram every two weeks during medication. The cardio-thoracic ratio was improved in 4 of 10 cases, the sum of RV+SV5 was decreased in all 5 cases who showed voltages above 40mm before medication, and PEP/LVET ratio was decresed in 4 of 10 cases. The difference of average values before and after medication were not statistically significant(p<0.05) in all 3 parameters when examined by t-test. During treatment, there was improvement, if any, from two weeks after medication and no significant side effects were noted throughout the study period.

Ganglia of the cruciate ligament are quite rare. About 60 cases were reported previously in the world and 6 cases were reported at two articles in korea. It's symptoms may be similar to those of internal derangement of knee, especially meniscal lesion. We report a case of isolated ganglion of posterior cruciate ligament with brief of literatures.

To determine factors involved in left ventricular aneurysm formation after transmural anterior myocardial infarction, 74 patients with a first myocardial infarction who underwent cardiac catheterization within 6 weeks of infarction were evaluated.Patients were divided into four groups depending on the status of the left anterioe descending artery(LAD) and the presence Group I(n=15);aneurysm with occluded LAD, Group II(n=16);no aneusrysm and occluded LAD, Group III(n=18);aneusrysm and patent LAD, and Group IV(n=25);no aneusrsm with patent LAD. Neither age, sex nor risk factors for coronary disease correlated with aneusrysm formation,but the duration of chest pain in patients with previous angina was significantly longer in group II(no aneusrysm with occluded LAD) compared with other groups(P<0.01). Single vessel disease was more commom in Group I and III(aneusrysm) compared with II and IV(no aneusrysm)(P<0.06). Collateral blood supply was more frequently observed in Group I and II(occluded LAD) compared with Group III and IV(patent LAD)(P<0.01) and was slightly less in Group I(aneusrysm) compared with Group II(no aneusrym)(P<0.07). Delta area decreasing rate of the left ventricle was significantly lower in Group I and III(aneusrysm)compared with Group II and IV(no aneusrysm)(P<0.01). Single vessel disease in assocition with poor collateral circulation tends to be a determinant of left ventricular aneusrysm formation after anterior myocardial infarction.

Studies of cancer heterogeneity have received considerable attention recently, because the presence or absence of resistant sub-clones may determine whether or not certain therapeutic treatments are effective. Previously, we have reported G64, a co-regulated gene module composed of 64 different genes, can differentiate tumor intra- or inter-subpopulations in lung adenocarcinomas (LADCs). Here, we investigated whether the G64 module genes were also expressed distinctively in different subpopulations of other cancers. RNA sequencing-based transcriptome data derived from 22 cancers, except LADC, were downloaded from The Cancer Genome Atlas (TCGA). Interestingly, the 22 cancers also expressed the G64 genes in a correlated manner, as observed previously in an LADC study. Considering that gene expression levels were continuous among different tumor samples, tumor subpopulations were investigated using extreme expressional ranges of G64-i.e., tumor subpopulation with the lowest 15% of G64 expression, tumor subpopulation with the highest 15% of G64 expression, and tumor subpopulation with intermediate expression. In each of the 22 cancers, we examined whether patient survival was different among the three different subgroups and found that G64 could differentiate tumor subpopulations in six other cancers, including sarcoma, kidney, brain, liver, and esophageal cancers.

With the recent increase of coronary artery disease in Korea, coronary arteriography israpidly gaining importance as a diagnostic procedure in the management of ischemic heart disease in this country. In order to delineate normal angiographic anatomy of the coronary arteries in Korean adults, the author reviewed 63 normal or near normal coronary angiograms out of 113 consecutive cases done at the cardiac laboratory of Yonsei University Severance Hospital from February, 1976 through September, 1982 and obtained the following results. 1) The diameter of the main stems of the left and the right coronary arteries measured 2.7-6.3mm(mean, 4.0mm) and 2.1-6.0mm(mean, 3.6mm) respectively, and the length of the left main stem measured 0-23mm(mean, 9.3mm). 2) The conus branch was visualized to originate from the proximal right coronary artery in 50 cases(79.4%), and in the other 13(20.6%) in whom the conus branch was not visualized, it was assumed to have a separate ostium directly from the aortic root. 3) The sinus node artery originated from the right coronary artery in 35 cases(55.5%) and from the left circumflex 20(31.7%). The remaining 8 cases(12.7%) appeared to have dual blood supply. 4) The artery to the A-V node arose from the proximal part of the posterior descending artery as a branch of the right coronary artery in 59 cases(93.7%) and of the left circumflex in only 4(6.3%), and the pattern of the A-V node blood supply coincided with the dominancy(crossing the crux of the heart and giving rise to the posterior descending artery) of the right or the left circumflex arteries. 5) In 33 cases(52.4%), both of the arteries to the SA and the AV nodes arose from the right coronary, and in 19(30.2%), the SA node artery came from the right, whereas the AV node artery originated from the left circumflex. 6) The number of ramifications(furcation) of the main left coronary artery was two in 53 cases(83.1%), three in 9(14.3%), and four in 1(1.6%). 7) The number of diagnoal branches of the left anterior descending artery was one in 34 cases(54%), two in 28(44.4%) and 3 in 1(1.6%).

Chronic constrictive pericarditis is an uncommon disease, but an importanat one because of its potential curability. It usually begins with an initial episode of acute pericarditis often with a pericardial effusion which may not be detected clinically. This then progresses to resorption of the effusion followed by obliteration of pericardial abity with formation of fibrotic tissue, which results in symmetrical scarring that produce uniform restriction. In general, there are no specific problems due to remained pericardial effusion in the clinically manifestated case of constrictive pericarditis. We report a case of chronic constrictive pericarditis with localized pericardial effusion, which caused to hemodynamic compromise due to local compression of the right ventricle.

Technetium 99 M pertechnetate has become a valuable for the radioisotopic brain scan. This was introduced by Haper in 1963 and is now widely used in the medical field. The advantages are easy administration, high count rate with potential for high speed scanning, absence of beta radiation and decreasing time for test. We used Siemens Scintimat 2 Scanner with a 3x2 inch Na(T1) crystal and 151-hole collimator in our study. 10 mci Technetium 99 M was injected intravenously and obtained both lateral, anterior and posterior view in 80 cases of brain lesion from Mar. 75 to Sep. 76. The scans were classified as positive, negative and suspicious. The overall detection rate in 40 cases of brain tumors was 60%, especially high uptake in mengioma, malignant pituitary tumor, astrocytoma, metastatic brain tumor and acoustic neuroma. But in nontumors diseases of the brain including CVA, head injury and hydrocephalus the uptake rate was a little value.
