BACKGROUND: It is known that left ventricular(LV) wall motion is not uniform even in normal heart, and the restoring forces make phase differences between LV wall motion and mitral flow velocity during rapid filling period. METHOD: To investigate the regional nonuniformity and restoring forces in 46 patients with hypertension(HT)(group:normal wall thickiness.n=12,II:LVH with fractional shortening(FS)>25%. n=22. III:FS<25%.n=12). We measured the time intervals from A2 to peak thinning rate point of LV posterior wall(A2-(-)dpw/dt).to mitral flow starting point (IRT).and to peak mitral flow velocity(A2-E) by M-mode and Doppler echocardiography. RESULTS: The noniformity((-)dpW/dt-dL/dt)and phase differance((-)dpw/dt-E) were increased in HT(control:HT.22+/-7.8 vs. 49+/-5.2msec, 63+/-4.5 vs, 86+/-6.2msec, p<0.05 respectively).In group comparison, nonuniformity increased in group II and III(group I: group II, III, 35+/-5.1 vs. 50+/-7.1,70+/-14msec, p<0.05 respectively). but phase difference increased only in group II(groupII: group I, III, 93+/-6.0 vs. 75+/-5.2, 80+/-20msec, p<0.05, respectively). CONCLUSION: We interpreted these data that in HT with hypertrophy or not, the nonuniformity of LV wall motion working on the restoring forces which can be expressed as phase difference between LV wall motion and mitral flow. But in HT with hypertensive heart failure group, no significant changes of phase difference and it's suggest that other mechanism could be also working on early diastolic filling.

BACKGROUND: A regional wall motion nonuniformity and a phase difference between LV posterior wall motion and transmitral flow are present during normal rapid filling period and are thought to be an evidence for involvement of ventricular restoring forces. To assess the role of nonuniformity on diastolic funtional impairment of asymmetric septal hypertrophy(ASH), the time relations between left ventricular regional wall motions and filling velocity were studied. METHOD: We measured the time intervals from A2 to peak rate of LV posterior wall(short axis) thinning(A2-(-)dpw/dt), peak rate of medial mitral annulus (long axis dimension) lengthening(A2-dL/dt) and peak mitral flow(A2-E) by M-mode and Doppler echocardiography. Result: In ASH patients, A2-(-)dpw/dt(106+/-6msec, mean SE) and the regional wall motion nonuniformity((-)dpw/dt-dL/dt, 89+/-11msec, mean SE) were increased significantly when compared with normal control values(88+/-4, 28+/-5msec, mean SE, p<0.01,respectively).In normal controls, peak mitral flow velocity lagged peak rate of regional wall motion, so the phase differences were present((-)dpw/dt-E :71+/-8msec, dL/dt-E:44+/-6msec). In ASH patients, (-)dpw/dt-E was present(90+/-16msec) but dL/dt-E was not present or reversed(-21+/-18 msec). So these chacteristic phase differences were disturbed. CONCLUSION: These data suggested that the relaxation nonuniformity of regional wall motion in ASH may act as an energy dissipating factor of restoring forces during rapid filling period.

BACKGROUND: To evaluate the safety and the efficacy of amlodipine, a dihydropyridine calcium antagonist, monotherapy in the treatment of moderate essential hypertension. METHOD: Amlodipine 5mg once a day was administered as a starting dose in 30 patients with essential hypertension in the morning and a one step upward titration was performed (amlodipine 10 mg once a day) was done at the end of 4weeks treatment. Final evaluation was done at 12weeks with laboratory test and echocardiogram. RESULT: Within 4weeks treatment with dose of 5mg amlodipine once a day, the systolic blood pressure (SBP) was decreased(184.5+/-23.3/150.5+/-16.0mmHg,p<0.000), and the diastolic blood pressure(DBP) was also decreased significantly (109.9+/-04.6/92.3+/-11.5mmHg, P<0.001). After 12 weeks of treatment with a mean dosage of 6.6mg once a day, SBP and DBP was maintained comparing with basal level (147.0+/-15.8/88.1+/-0.9mmHg, respectively). The efficacy of amlodipine treatment was noted an excellent in 16 patients(53.3%), good in 4 patient(13.3%), fair in 4 patients(13.3%), and failed in 2 patients(6.7%). There was no significant change in heart rate before and after amlodipine treatment. (80.0+/-2.3/80.9+/-10.4 beats/minute n.s). Amlodipine had not significant effects on laboratory findings such as serum creatinine, BUN, ALT/AST, hemoglobin, leukocyte count,platelet and lipid profiles. There was facial flushing 2 patients, but no need to discontinue administration of amlodipine and all patients completed for 12weeks therapy. CONCLUSION: It is concluded that amlodipine is an effective antihypertensive agent, as monotherapy once a day in patients with moderate essential hypertension.

The antihypertensive effect of Doxazocin were evaluated in 20 patients with essential hypertension. Two to eight mg of Doxazocin per day were administered continuously for two or eight weeks. The results were as follows : 1) Doxazocin were effective in 18 out of 20 patients(90%) at the end of 8 weeks treatment. 2) The systolic blood pressure was signigicantly decreased(173+/-20mmHg VS 144+/-33mmHg, P+/-0.001), and the diastolic blood pressure was also decreased(110+/-10mmHg VS 93+/-19mmHg, P<0.01) after treatment. 3) Triglyceride showed a decreasing tendency but statistically significance was not observed. Total cholesteral, HDL-cholesterol, BUN, creatinine, and uric acid did not change significantly before and after treatment with Doxazocin. 4) The side effects were headache in one case and dizziness in to cases. These results suggest that Doxazocin is an effective antihypertensive agent and concerning lipid profile, further long term observation is needed.

Time intervals and indices of left ventricular diastolic filling were studied by M-mode and pulsed Doppler Echocardiography in 18 dilated cardiomyopathy patients. After one two hours captopril(capril(R)) 25mg medication. 1)Systolic blood pressure, Diastolic blood pressure, Heart rate were significantly decreased. 2) Dimensions of LVSD, LVDD, LA, Aorta and EF were not changed measured by M-mode echocardiography. 3) IRT measured by M-mode and Pulsed Doppler echocardiography were significantly increased(45+/-33msec VS 74+/-35msec. 84+/-32msec VS 100+/-22msec P<0.05). 4) A2-E measured by M-mode and Pulsed Doppler echocardiography were significantly increased(114+/-45msec VS 134+/-46msec, 156+/-46msec VS 194+/-48msec, P<0.05). 5) Deceleration time was significantly increased(137+/-36msec VS 205+/-40msec P<0.05). 6) Transmitral peak flow velocities were not changed significantly. In summary captopril influences early diastolic time intervals with dilated cardiomyopathy patients and we interpreted these effects be beneficial on diastolic filling pattern.

From January 1988 to December 1991, 39 fractures of the lateral condyle of humerus in children were treated at the Department of Orthopaedic Surgery, Sung-Ac General Hospital. It was possible to follow up from one year to four years and eleven months. The authors have analyzed the method of treatment on the basis of the degree of displacement in the change of Carrying angle and Baumann's angle. The results were as follows; 1. Of the 39 cases, the age incidence was confined to 2 to 12 years of age and the average age of the patients were 5 years. 2. Most fractures were Milch type II (29 cases) in contrast to Milch type I (10 cases). 3. According to the initial displacement of the fracture, 8 cases were Jokob's stage I, 21 cases of stage II & 10 cases of stage III. 4. There were no significant difference in the range of change of Carrying angle and Baumann's angle according to initial displacement of fracture site. However, significant difference in outcome were noticed from open reduction and internal fixation in comparison to closed reduction and percutaneous pinning. 5. In all 39 cases, lateral condylar overgrowth (10 cases), cubitus varus (1 cases) and cubitus valgus (3 cases) were noticed as complications but clinical significance was not noted. 6. The above results suggest that internal fixation is recommended for firm fixation although displacement is not severe. In case of Jakob's stage III, anatomical reduction is required in order to reduce additional damage on articular surface and epiphyseal plate caused by excessive manipulation.

Congenital fibrosarcoma of neonate is a very rare malignant tumor prone to behave aggressively with a tendency to local recurrence without metastasis. It is characteristically composed of collagenous fibroblasts and herringbone pattern in histology. We experienced a case of congenital fibrosarcoma on the left thigh and report this case with some review in literature with 1½ year follow up.

BACKGROUND: The effective ventricular function during ejection and filling is likely to depend on the coordinated action of the longitudinally and circumferentially orientated myocardial fibers and the function of these longitudinal fibers has not been extensively studied. METHODS: The role of longitudinally and circumferentially orientated fibers in left ventricular wall motion was evaluated by M-mode echocardiograms of the mitral ring(whose motion reflect long axis change) and the standard minor axis(left ventricular posterior wall), simultaneous recordings of phonocardiograms and electrocardiograms on the paper (speed 100mm/sec), in 24 healty individuals, 17 patients with mitral stenosis, 11 patients with open mitral commissurotomy and 17 mitral valve replaced patients. RESULTS: In the controls long axis shortening significantly preceded minor axis shortening (phase difference between two axes : 20+/-3 msec, mean+/-SEM) during early systole, indicating left ventricle become more spherical. This phase difference was also observed in the patients with mitral stenosis and in those with open mitral commissurotomy. In patients with mitral valve replacement(MVR) whose papillary muscles had been sectioned, the onset of long axis shortening was more delayed during early systole than that of short axis(-33+/-6msec) and the end of shortening was also prolonged to early diastole more than that of normal controls (54+/-3 msec vs 90+/-8 msec, mean+/-SEM, p<0.01 by t-test). CONCLUSION: We observed the time relations between long and short axis motion in normal controls. It can be concluded that the reversed time relation in patients with MVR is one of the important factors which may effect negatively on ventricular function and long-term prognosis, thus the surgical procedures to preserve papillary annular continuity should be considered in patients with mitral valvular disease. And the controlled, prospective, clinical trials with homogenous groups of patients are needed to evaluate the potential benefits of papillary annular continuity in preserving atrio-ventricular interaction in patients undergoing mitral valvular surgery.

BACKGROUND: In previous study, hypertensive patients with left ventricular diastolic dysfunction showed delayed relaxation time intervals and increased relaxation nonuniformity of regional wall motion. In this point of view, the effects of amlodipine on the regional wall motion and mitral flow patterns were evaluated. METHODS: Before and 32weeks after the antihypertensive medication of amlodipine, M-mode & Doppler echocardiogram were performed in 14 patients with moderate hypertension. We measured A2 to the peak thinning rate point of left ventricular(LV)posterior wall [A2-(-)dpw/dt] and the peak lengthening rate point of mitral annulus [A2-dL/dt] on M-mode echocardiogram and we defined nonuniformity as the time interval, (-)dpw/dt-dL/dt. RESULTS: 1) Mitral flow velocity E/A ratio was increased (0.95+/-0.4 vs 1.42+/-0.6, p<0.05) after amlodipine medication. 2) Heart rate and LV posterior wall thickness was decreased (79+/-9.3 vs 72+/-10.8 beats/min, 10.7+/-1.5 vs 9.4+/-2.0mm, p<0.05 respectively). 3) Long axis relaxation was improved (A2-dL/dt ; 165+/-44 vs 140+/-23msec, p<0.05) and nonuniformity index was decreased ((-)dpw/dt-dL/dt ; 63+/-49 vs 41+/-30msec p=0.07). CONCLUSION: Amlodipine improved E/A ratio of mitral flow (E/A ratio) in hypertensive patients with diastolic dysfunction, which could be attributed to the decreased heart rate, the decrease in wall thickness and the improvement in relaxation movement of LV long axis.
