OBJECTIVES: The purpose of this study was to identify the effects of aerobics and aquarobics exercise programs on elders' leg muscle strength, balance and walking ability in elders. The participants of the study were 21 elders; 11 of them participated in the aerobics exercise program and 10 of them participated in the aquarobic exercise program. METHODS: Both of the participants practiced for 10 weeks. The data were analyzed with using two-way ANOVA with repeated measures on the last factor. RESULTS: The results were summarized as follows: First, the main effect of exercise programs(aerobics x aquarobics) and the interaction effect between the exercise programs and the leg muscle strength were not significant. Second, the participants' static balance of the aquarobics exercise program increased more than that of the aerobics exercise program. Third, the participants' dynamic balance of the aquarobics exercise program increased more than that of the aerobics exercise program. Fourth, the main effect of exercise programs and the interaction effect between the exercise programs and the increase in gait speed were not significant. Fifth, the participants' step length of aquarobics exercise group increased more than that of the aerobics exercise program. All of the participants' leg muscle strength, static balance, dynamic balance, gait speed and step length increased after the both of two exercise programs. And, more importantly, the positive effect of the aquarobics exercise program on static balance, dynamic balance and step length was stronger than that of the aerobics exercise program. CONCLUSIONS: These results suggest that the aquarobics exercise program be more effective exercise on elders' balance and walking ability than the aerobics exercise program.

Most studies on the pathophysiology, natural history, diagnosis by imaging and outcomes after operative or nonoperative treatment of rotator cuff tear have focused on those of full-thickness tears, resulting in limited knowledge of partial-thickness rotator cuff tears. However, a partial-thickness tear of the rotator cuff is a common disorder and can be the cause of persistent pain and dysfunction of the shoulder joint in the affected patients. Recent updates in the literatures shows that the partial-thickness tears are not merely mild form of full-thickness tears. Over the last decades, an improved knowledge of pathophysiology and surgical techniques of partial-thickness tears has led to more understanding of the significance of this tear and better outcomes. In this review, we discuss the current concept of management for partial-thickness tears in terms of the pathogenesis, natural history, nonoperative treatment, and surgical outcomes associated with the commonly used repair techniques.

OBJECTIVE: Although cor pulmonale due to chronic lung disease was not uncommon, there was uncertainty in its diagnosis due to the difficulty in measuring functional and anatomical changes of right heart and pulmonary vascular system. Among various non-invasive diagnostic methods presented so far, no ideal standard diagnostic criterion has been established. The authors attempted to know positive diagnostic ratio of cor pulmonale and to study the presence of the relationship between these diagnostic criteria when electrocardiographic and echocardiographic diagnostic criteria for cor pulmonale were applied to the patients with chronic lung disease. And we investigated the usefulness of echocardiogaphic diagnostic criteria for the diagnosis. METHODS: One electrocardiographic and two echocardiographic diagnostic criteria were applied to 38 patients with chronic lung disease(21 pulmonary emphysema and 17 chronic advanced pulmonary tuberculosis) for the diagnosis of cor pulmonale. Comparison was also made in their relationship. Then pulmonary artery diameter, measurement of pulmonary function test and echocardiographic examination and radio-nuclear right ventricular ejection faction were compared between the groups to ensure each criterion was satisfied. RESULTS: 1) When the three diagnostic criteria for confirming the cor pulmonale, electrocardiographic rriterion(right ventricular hypertrophy), right ventricular dimension criterion(right ventricular end-diastolic dimension>25mm, RVDd>25mm), and right ventricular wall thickness criterion (right ventricular wall thickness>6mm, RVWT>6mm) were applied to the patients, the positive rate were 32%(12/37), 30%(10/33) and 17%(6/36) respectively. A statistically significant correlation between electrocardiographic criterion and right ventricular wall thickness criterion was found to exist. 2) Various parameters of pulmonary function test and echocardiographic examination were compared in the patient groups with and without cor pulmonale when each non-invasive diagnostic criterion was applied to all patients. Followings are the results. (1) In the positive group on electrocardiographic criteria, vital capacity, forced vital capacity, and arterial oxygen tension were significantly smaller than in the negative group on electrocardiographic criterion(p<0.05), and the echocardiographic parameters of right ventricle, ie. end-diastolic area, end-systolic area, end-diastolic dimension, end-systolic dimension, mid-ventricular short axis and maximal short axis in positive group were significantly larger than in the negative group. (2) In the positive group on right ventricular diastolic dimension criterion(RVDd>25mm), percentage forced expiratory volume in 1 second and forced expiratory flow 25-75% were significantly smaller than in the negative group on right ventricular diastolic dimension criterion. (3) In the positive group on right ventricular wall thickness criterion(RVWT>6mm), vital capacity, forced vital capacity, forced expiratory volume in 1 second, forced expiratory flow 25-75% and arterial oxygen tension were significantly smaller than in the negative group on right ventricular wall thickness criterion. CONCLUSION: When several non-invasive diagnostic criteria for cor pulmonale were applied to the patients with chronic lung disease, there were some differences in its positive diagnostic ratio depending on the applied diagnostic criteria. There was also a statistically significant correlation between electrocardiographic criterion and right ventricular wall thickness criterion. When each diagnostic criterion was applied to the patients, significant differences were found in several parameters resulted from pulmonary function test and echocardiographic examination based on presence or nonpresence of cor pulmonale. But no difference in the ejection fraction measured by radio-nuclear method was shown between cor pulmonale group and non cor pulmonale group. Consequently it was suggested that applying echocardiographic criteria in addition to electrocardiographic criterion for the diagnosis of cor pulmonale in the patients with chronic lung disease is clinically useful.

The elbow region is the most common site at which the ulnar nerve is prone to a localized neuropathy. Diagnosis of ulnar nerve entrapment at elbow is made on the basis of history, lacal neurologic finding, nerve conduction studies and electromyography. Electrophysiologic test is simple, relatively quick, and accurate method for the diagnosis of peripheral nerve lesion. Therefore, electrodisgnosis makes it possible to identify and localize the early stage of entrapment lesion. Definitive diagnosis of ulnar nerve entrapment at elbow requires electromyographic demonstration of decreased ulnar nerve conduction velocity across the elbow and depressed sensory nerve action potentials. The purpose of this study were to analyze the electrophysiologic findings of patients with an established ulnar nerve entrapment at elbow compared to normal eonduction velocity of our laboratory. And we evaluate the correlation of clinical symptom with the electromyographic findings. Twenty five subjects were studied, 22 men and 3 women, aged from 5 to 62 years. The results were as follows . 1. The mean motor conduction velocity of ulnar nerve across elbow were 32.85±10.21 m/sec. The longer duration of symptom were, the slower conduction veloctity across elbow were. 2. Among the 25 patients, motor conduction velocity of ulnar nerve at forearm segment decreased in 15 patients(60%). As the motor conduction velocity of the ulnar nerve across elbow became slower, thst of forearm segment were slower. 3. In 19 patients (76%) among the 25 patients, sensory evoked potentials revealed prolonged distal latency or were not evoked. 4. On needle electrodiagnostic study, positive sharp wave or fibrillation potentials could be found in abductor digiti minimi first dorsal interosseus and/or flexor carpi ulnaris muscles in 22 patients(88%).

A simple, rapid and selective liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) is developed and validated for quantification of venlafaxine in human plasma with simple liquid-liquid extraction step consisted of extraction with ether and dichloromethane for 10 min and mixing with 1 M sodium acetate in human plasma using fluoxetine as an internal standard (IS). The analyte are separated using an isocratic mobile phase consisted of acetonitrile and 5 mM ammonium formate (4/3, v/v) on a isocratic YMC hydrosphere C18 (2.0x50.0 mm, 3.0 microm) column and analyzed by MS/MS in the multiple reaction monitoring (MRM) mode using the transitions of respective [M+H](+) ions, m/z 278.2-->260.3 and m/z 310.1-->148.1 for quantification of venlafaxine and IS, respectively. The standard calibration curves showed good linearity within the range of 1.0-200.0 ng/mL (r2=0.9986, 1/chi2 weighting). The lower limit of quantification (LLOQ) was 1.0 ng/mL. The retention times of venlafaxine and IS were 0.6 min and 0.7 min that means the potential for the high-throughput potential of the proposed method. In addition, no significant metabolic compounds were found to interfere with the analysis. Acceptable precision and accuracy were obtained for the concentrations over the standard curve range. The validated method was successfully applied to bioequivalence study after 75-mg of venlafaxine sustained-release (SR) capsule in 24 healthy Korean subjects.

BACKGROUND: The safety of ergonovine provocation for coronary vasospasm (CVS) performed outside the catheterization laboratory has been questioned. We sought to address the issues of safety, feasibility and clinical impact of noninvasive diagnosis of CVS. METHOD AND RESULTS: We retrospectively analyzed the results of bedside ergonovine provocation testing with monitoring of left ventricular regional wall motion abnormalities (RWMAs) by 2-dimensional echocardiography (ergonovine echocardiography, Erg Echo). After confirmation of no significant fixed epicardial coronary artery disease, 1,504 Erg Echo were performed in 1,372 patients from July 1991 to December 1997. Erg Echo was prematurely terminated in 13 patients (0.9%) due to limiting side effects unrelated with myocardial ischemia. Among 1,491 completed tests, 32% (477) showed positive results with development of RWMAs in 467 tests (98%) or ST displacement in ECG in 10 tests (2%). During the test, transient arrhythmias developed in 1.7% (26/1491) including transient ventricular tachycardia (2) and atrioventricular block (4), which were promptly reversed with nitroglycerin. There were no procedure-related death or development of myocardial infarction. On the basis of angiographic criteria in 218 patients, who also underwent invasive spasm provocation test during coronary angiography, the sensitivity and specificity of Erg Echo for the diagnosis of CVS were 93% and 91% respectively. From 1990 to 1997, total 2,073 spasm provocation tests were performed either during invasive coronary angiography in the catheterization or in the echocardiography laboratory. Since 1994, noninvasive Erg Echo became a more popular diagnostic method and comprised more than 95% of all spasm provocation tests in recent 3 years. Erg Echo was also performed safely in outpatient clinic setting without hospital admission in 34% (500/1491). CONCLUSIONS: Erg Echo is highly feasible, accurate and safe for diagnosis of CVS and can replace the invasive spasm provocation test during coronary angiography in the catheterization laboratory.
