Essential hypertension is an important public health problem in Korea-being common, asymptomatic, easily treatable, and often leading to lethal complication in left untreated. The number of patients with hypertension has been significantly increased, and this factor may be an importnat one responsible for the increase in cardivascular mortality during past 20 years in Korea. As the drug therapy for hypertension needs longer period, it is very important to evaluate the efficacy and the adverse effects. Thirty patients(17 men and 13 womon) with essential hypertension were evaluated in this study. All patients had received oral Isradipine 1.25~2.5mg b.i.d. for 8 weeks. 1) The systolic and diastolic pressure were decreased significantly(166.8+/-9.0mmHg vs 147.3+/-12.0mmHg, p<0.001 and 100.3+/-4.0mmHg vs 90.3+/-6.1mmHg, p<0.001, respectively) 2) Heart rate, body weight, laboratory tests, chest X-ray, ECG studies were not changed significantly. 3) The systolic pressure was lowered by 20mmHg or more in 17 cases(56.7% of total), and the diastolic pressure was lowered by 10mmHg or more in 20 cases(66.7% of total) at 8 weeks after Isradipine administration. 4) The adverse effects of Isradipine were edema in 3(10%), constipation in 2(6.7%), headache in 2(6.7%), and insomnia, dizziness and dry mouth in 1 patient respectively, and none of them discontinued Isradipine administration due to adverse effects. In many patients with essential hypertension there is an effective response to Isradipine, even though there may be some mild adverse effects.

Although causes of restriction of knee extension in osteoarthritis are thought to be contractures involving the posterior capsule and the hamstring muscles, intercondylar notch stenosis, osteophyte, loose body, and displacement of ruptured meniscus, few studies have investigated incidence and treatment. The purpose of this study is to consider intercondylar notch stenosis and anterior impingement as major causes of flexion contracture in osteoarthritic knee and to assess their relationship through arthroscopic notchplasty. We performed arthroscopic notchplasty and debridement in sixty patients (sixty-eight cases) with more than Sflexion contracture for early osteoarthritic knee and compared flexion contracture before and after operation. The average flexion contracture was 13degrees (5degrees-35degrees) before operation and 4degrees (0degrees- 25degrees) immediately after. An average of 9degrees improvement was shown, with 29 cases ( 48% ) showing improvement of over 5degrees. Our study indicates that flexion contracture in the 29 cases (48%) improved by arthroscopic notchplasty was caused by intercondylar notch stenosis and anterior impingement. Arthroscopic notchplasty may beneficially affect those with flexion contracture in early osteoarthritic knee when conservative management of this disease has failed. This is a preliminary study on the immediate postoperative outcome, therefore, long-term follow-up and recurrence rate should be investigated in future studies.

Previous applications of laser bone and cartilage ablation have focused largely on the CO2 and the Nd:Yag lasers, using both the continuous wave and rapid superpulsed mode, which revealed severe thermal damage such as tissue necrosis and carbonization of the remaining tissue. In contrast, Excimer lases have provided better histologic results with minimal or no thermal damage, but the ablation rate and cutting efficiency have remained unsatisfactory. Though arthroscopic partial menisectomy has become the accepted technique for dealing with tears in menisci, division of the meniscus is sometimes difficult in the confined joint space of the knee and is associated with iatrogenic injury to the articular cartilage. The ability to quickly and safely divide or remove meniscal tissue would be a distinct advantage. The Holmium:Yag laser has many potential advantages over the CO2 laster, the Nd:Yag laser and the Excimer laser. Its principal advantages include minimal mechanical trauma to the articular cartilage, greater access to tight or restricted area of the knee joint, and its ability to function in a saline medium and to resect meniscus with minimal tissue necrosis. We have evaluated the effectiveness of the Holmium:Yag laser 74 partial menisectomies of 57 patients. Among 74 meniscal tears, there were 35 medial and 39 lateral meniscal tears. The average operation time was 33 minutes in the menisectomy and hospital stay was average 3 days. There was no significant carbonization on the surrounding tissue. Menisectomy of the posterior horn was safe and easy and there was minimal iatrogenic articular cartilage damage.

A reproducible noninvasive technique for measuring right ventricular ejection fraction (RVEF) was developed using first pass quantitative radionuclide angiocardiography. Tests were carried out in the right anterior oblique position with a computerized multicrystal scintillation camera with high count rate capabilities. RVEF was calculated on beat to beat basis from the high frequency components of the background-corrected right ventricular time-activity curve. The following results were obtained; 1) In 10 normal adults, RVEF averaged 50.9+/-8.2. In 20 patients with chronic obstructive lung diseases (COPD), RVEF was 37.9+/-6.1% and significantly lower than that of normal persons(P<0.005). 2) There was meaningful correlation between RVEF and forced expiratory volume (FEVI) in patients with COPD (r=0.51). And there was significant difference of RVEF between 13 patients with FEVI less than IL/min (6 patients with right ventricular failure, 7 patients with patients without that) and 7 patients with FEVI IL/min or more (35.7+/-6.0%, 42.1+/-3.2% respectively. P<0.005). 3) All 6 patients with clinical manifestation of right heart failure had abnormal RVEF and had FEVI less than IL/min, which was significantly lower than that of 14 patients without clinical manifestation of right heart failure (33.6+/-4.8%, 39.8+/-5.6%, respectively. P<0.005). 4) In 14 patients without clinical manifestation of right heart failure, 11 patients among whom 7 patients had FEVI less than IL/min, had abnormal RVEF.

BACKGROUND: In patients after acute myocardial infarction, signal-averaged electrocardiography is used as the one of the non-invasive methods for the prediction for ventricular arrhythmia, one of the causes ofn death in acute myocardial infarction. Signal-averaged electrocardiography has allowed the identification of low-amplitude, high-frequency signals(late potentials)in the terminal portion of the QRS complex. They are thougt to be occured in the portion of electrophysiologically unstable myocardium. The presence of late potentials identifies regions of delayed conducton in the elctrophysiologically unstable border zone of an acute infarction. These electrophysiologic change of myocardium is influenced by the patency of infarct-related artery. A patent artery is associated with electrical stability of myocardium, decreased in cidence of late potentials and improved survival. METHODS: 58 patients of acute myocardial infarction underwent signal-averaged electrocardiography, coronary angiography within 10 days after AMI, 20 of healthy persons underwent signal-averaged electrocardiography. RESULTS: In patent group, late potentials were recorded in 7 of 38 patients(18%) as compared with 13 of 20 patients(65%) of non-patent group. The statistically significant parameters of signal-averaged electrocardiography beteen patent and non-patent group were filtered total QRS duration(TQRS, 106.7+/-20.9msec), high frequency low amplitude signal (HLAS, 30.8+/-7.5 vs 41.3+/-16.5 msec)with HLAS being the most powerful varialble in the model. CONCLUSION: These results suggest that the patency of infarct-related artery is associated with electrophysiologic stability of myocardium and signal-averaged electrocardiography is one of the useful non-invasive method in risk stratification of acute myocrdial infarction.
