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.

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.

BACKGROUND: This study was designed to evaluate the safety and the efficacy of fosinopril(Monopril(R)) in the treatment of mild to moderate essential hypertension. METHOD: Fosinopril(10mg) once a day was administrated as a starting dose in 20 patients with essential hypertension in the morning and a one step upward titration was performed(fosinopril 20mg once a day, after 4 weeks treatment). RESULT: After 2 weeks treatment with dose of 10mg, the systolic blood pressure(SBP) was decreased(183.8+/-28.5 vs, 161.5+/-25.9mmHg, p<0.05) and the diastolic blood pressure(DBP) was also decreased significantly(108.3+/-9.3 vs, 96.6+/-10.3mmHg, p<0.05). The effect of fosinopril were maintained. The SBP an DBP were decreased in 14 out of 20 patients till 8 weeks. There was no significant change in heart rate before and after fosinopril treatment(74.3+/-10 vs, 76.4+/-7.9beats/min). Fosinopril had no significant effects on laboratory findings such as serum creatinin, BUN, AST/ALT, WBC, Platelet and lipid profiles. Mild dry coughing was noticed only in 5 patients and it did not disturb continuing medication. CONCLUSION: Fosinopril is an effective antihypertensive agent, as monotherapy once a day in patients with mild to moderate hypertension.

BACKGROUND: Viral myocarditis is considered as a cause of dilated cardiomyopathy. At present, two pathogenic mechanisms may be involved in the pathogenesis of viral myocarditis and subsequent cardiomyopathy. First, the virus infection of myocyte may directly lead to either cell death or persistent metabolic dysfunction. Second, virus-induced immune or autoimmune mechanism may play a role. METHODS: To test the therapeutic efficacy of immunosuppression with cyclophophamide(CYP) on coxsackievirus B3(CB3) myocarditis, 10-14 week-old Balb/c mice were inoculated with 4000 plaque-forming units of CB3. In experiment 1, CYP (100mg/kg/day subcutaneous injection, s.c) was administrated daily on days 1-7(group 2, n=16). In experiment 2, CYP 30mg/kg/day s.c(group 3, n=32) or CYP 100mg/kg/day s.c(group 4, n=32) were administrated on days 8-14. The animals of infected controls(group 1, n=26) and group 2, 3, 4 were dissected at days 4, 7, 15, 22 and spleen, heart, thymus and body weights were measured. RESULTS: In experiment 1. survival rate in group 2 on day 7, 15 were low compared with group 1(85%, 0% vs 100%, p<0.05). and myocardial virus titers in group 2 on day 4 was 50 times, and on day 7, 1000 times higher compared with group 1, Histologically, on day 7, focal cellular infiltrations were prominent findings in group 1, but diffuse myocardial necrosis without cellular infiltration were observed in group 2. In experiment 2, survival rate, cardiac histopathology myocardial virus titer and serum neutralizing antibody titers did not differ among groups 1, 3 and 4. In experiment 1 and 2, the spleen-to-body-weight and thymus-to-body-weight ratios were significantly lower in CYP treated groups than those in controls and marked cellular depletions in spleens and thymus were observed in CYP treated groups. CONCLUSIONS: As the results of above, it can be concluded that the immunosuppression during viremic phase of murine viral myocarditis aggravated the myocardial necrosis, and during aviremic phase, the administration of CYP didnot affect the process of viral myocarditis. Thus, direct viral mechanisms in the production of cardiomyocyte injury in CB3-infected mice appear to bo more important than cell mediated immune mechanism. To understand relevant pathogenic mechanisms of clinical myocarditis and dilated cardiomyopathy resulting from viral infection, the experimental study expanding into nonmurine animals and into various models using other infectious agents may be required.
