BACKGROUND: To evaluate the usefulness of exercise echocardiography in diagnosis of coronary artery disease and to compare it with exercise ECG test. METHOD: We performed exercise test in 48 patients who suffered from angina-like chest pain, according to the modified Bruce protocol. During exercise, we observed the ECG changes and recored the images of left ventricular wall motion before and after exercise on the video tape. The echocardiogram were digitally stored and displayed in a format that allowed simultaneous analysis of rest and stress images. Newly developed left ventricular wall motion abnormalities were determined as positive findings. RESULTS: The feasibility of exercise echocardiography was 75%. The sensitivity and specificity fo exercise ECG test was 67% and 89%. The sensitivity and specificity of exercise echocardiography was 85% and 100%. The sensitivity of ECG and echocardiography was 50%(7 of 14) and 78.6%(11 of 14) in those with one-vessle disease and 84.6%(11 of 13) and 92.3%(12 fo 13) in those with multi-vessle disease. CONCLUSION: Exercise stress echocardiography was very usefull method for detecting the coronary artery disease especially in single vessle disease. And it had much higher accuracy than the stress ECG test.

BACKGROUND: It has been suggested that mitral regurgitation(MR) of hypertrophic cardiomyopathy is associated with left ventricular outlet pressure gradient, systolic anterior motion of mitral leaflet, abnormal coaptation of mitral valve, malalignment of papillary muscle and elongation of mitral leaflet. To investigate the relation between the degree of MR and the several causing factors, we reviewed 35 patients with hypertrophic cardiomyopathy. METHOD: 35 patients with hypertrophic cardiomyopathy were classified into a group I(24 patients) without mitral regurgitation and with grade 1 MR or a group II(11 patients) with grade 2 and grade 3 MR. Measurement of mitral leaflet was performed on 2-D echocardiography. Distance between interventricular septum and systolic anterior motion(SAM) of the mitral leaflet was measured on M-mode echocardiography. RESULT: 1) Mitral regurgitation was observed in 22 patients(63%) among 35 patient. 2) Left ventricular outflow pressure gradient was 11+/-10mmHg in group I, 79+/-68mmHg in group II(p<0.05). Interventricular septum-SAM distance was 1.0+/-0.3cm in group I, 0.3+/-0.5cm in group II. 3) Anterior mitral leaflet length was 2.76+/-0.51cm in group V, 2.89+/-0.34cm in group II and posterior mitral leaflet length was 1.71+/-0.43cm in group I, 1.80+/-0.29cm in group II(p>0.05). 4) Mitral annulus circumference was 8.57+/-1.13cm in group I, and 8.58+/-0.92cm in group II(p>0.05). CONCLUSION: There was no correlation between the degree of mitral regurgitation and mitral leaflet length or mitral annulus circumference but, left ventricular outflow pressure gradient and interventricular septum-SAM distance were good correlated with degree of mitral regurgitation.

The patellar tendon is known as the strongest material for the substitution of anterior cruciate ligament. There are many technical difficulties in reconstruction of the ligament with this tendon since patellar aponeurosis is weak, and the length of the tendon is restricted, and the adquate insertion in proper place is difficult. Authors harvested the middle 1/3 of patellar tendon c bone block of tibial tubercle and patella with the superficial layer of the quadriceps tendon left attached. The large triangular tibial tubercle piece was impacted into the femoral tunnel from distally to proximally, of which the orifice is the very place of the middle of the original anterior cruciate ligament. Two bundles of 0-dexon sutures made at the tibial tubercle portion, were pulled through to different outlet of femoral condyle during this procedure and were tied over the cortical bone of lateral supracondylar region. The tendon twisted 180°(clockwise for the right knee and counter-clockwise for the left knee) to adapt to screwhome movement. The patellar piece was fixed at the isometric point in full flexion and extension, which is usually the middle point of original tibial insertion c one or two barbed staples made at the original position of tibial insertion of the ligament. We tried this methods in 26 knees (12 vascularized grafts and 14 free grafts) and was followed for more than one year and the results was compared with those of 12 knees of original McIntosh operation (follow up period: 16-72 months, average 34.3 months). The instability were evaluated c Lachman test and OSI sagittal knee tester. The knee of negative Lachman test & pivot shift test was defined as "normal" The results were as follows;l. In modified McIntosh operation group negative Lachman test was noted only in 6 knees (50.0 % ) and there were 2 knees (16.7% ) of GI, II & III, respectively. 2. In vascularized bone block patellar tendon graft group II out of 12 knees (91.7%) showed negative Lachman test and only one knee (8.3%) revealed G II. 3. In free bone block patellar tendon graft 13 out of 14 knees (92.9%) showed negative Lachman test and the other one knee (7.1%) revealed GI. 4, The overall success rate (normal) of bone block patellar tendon graft was 92.3%. The success rate of patellar tendon bone block operation was significantly higher than that of modified McIntosh operation (χ²=6.48, df=1, P=0.0109) and there was no statististical difference between vascularized and free graft group (χ²=0.39, df=l, P=0.5322).

Finger print patterns were studied in a series of 99 male schizophrenics who met with the diagnostic criterias of International Pilot Study of schizophrenia except items associated with chronicity in exclusion criteria, As controls, the autbors used 400 Korean men who were free of congenital, dermatological, neurological and psychiatric disorders, The frequency distribution of the finger print patterns in the 99 s'chizophrenics were whorls 52.45%, loops 49.09% and arches 3.46%. and that of controls were vrhorls 49.65%, loops 46.38% and arches 3.97%, The diffeence in pattern frequency was statistically significant (P<0.05). However, the striking differences were found in the frequency of the ridge dissociation. The observed frequency was very significantly high (p<0.005) in the schizophrenics (16.16%) compared to controls (6.25%). This findings supported the rcport of the Raphael (18%) but the frequency of our controls(6.25%) were not matched with previous study of Abel (The frequency for his 4,000 control was negative. No plausible explanation is not found for the extraordinary high frequency of ridge clissociat,ions in the controls of tbis study. Although rnore extensive investigation in needed for the explanation of significantly high frequency of ridge dissociation in thes chizophrenics, the findings of the present study give us another evidence of the constitutional factors in schizophrenics.
