To stydy the parameters of preload, afterload, and contractility of the heart, we evaluated 10 mitral stenosis, 5 mitral stenoinsufficiency, and 5 mitral stenosis with aortic insufficiency by measuring the external energy potential, external mechaical work, and external energy potential to PVa(Pressure-volume Area) ratio with non-invasive method, echocardiography and carotid pulse tracting. The results are summarized as follows; 1) External energy potential of mitral stenosis was significantly higher than that of MSI or MS with AI. 2) External mechanical work of MSI or MS with AI was significantly higher than that of Ms. 3) External energy potential to PVA ratio was signifiantly higher in the MS, but there was no significantly difference between the MSI and MS with AI. According to the above results, external energy potential to PVA ratio with echocardiogram and carotid pulse tracting was good parameters of preload, afterload, and contractility. And this method may used bed-side monitoring in the clinical area.

Real-time ultrasongraphy is a simple, accurate, noninvasive and potentially valuable means of studying gallbladder size and emptying. The authors calculated ultrasonographically the ejection fraction of 80 cases of normally functioning gallbladder on oral cholecystography, from June 1983 to April 1984, at the department of radiology, Hangang Sacred Heart Hospital. The results were obtained as follows; 1. Ultrasongraphic Ejection Fraction at 30 minutes after the fatty meal was 73.1+-16.85. 2. There was no significant difference in age and sex, statistically.

The significance of the posterior cruciate ligament (PCL) in the stability of the knee and the necessity for surgical repair of its tears are still controversial. The purpose of this study is to present the short term results of surgical repair and Kennedy LAD augmentation for 15 cases with PCL injury. In 14 patients (15 knees), the torn PCL was repaired with pullout suture technique and Kennedy LAD augmentation was done from june 1993 to june 1994. The follow-up period ranged from 12 months to 25 months (average, 18months). The main causes of injuries were traffic accidents in 12. Thirteen of the patients were men and one was a woman, ranging in age from 17 to 52 years(average, 35 years). 10 knees were acute injury and repaired at average 9 days after injury. There were 11 cases that had combined injuries(4 ACL injuries, 4 meniscus injuries, 3 MCL injuries etc). In eight knees, the tear was in mid substance area and in five it was near femoral attach site and in two it was near tibial attach site. Postoperative results were evaluated by roentgenographic evaluation of posterior sagging and Lysholm knee score. 11 knee were stable but 4 knees were unstable posteriorly during postoperative follow-up period. 3 chronic injuried knees were included in 4 posteriorly unstable knees. There are 7 combined knee injuries in 11 stable knees and no combined injuries in unstable knees and average Lysholm knee score was 89.7 in stable knees and 90 in unstable knees and there was no significant difference between two groups. On the based of this study, surgical repair with pollout suture technique and augmentation with Kennedy LAD in acute PCL injury is a one of the good method for preventing posterior sagging but more longer follow-up period and more cases must be needed to accept this method.

BACKGROUND: Non ulcer dyspepsia(NUD) is a commonly encountered disease at the primary practice. The relations of functional gastrointestinal disorder and Irritable bowel syndrome with depression or stress were suggested by previous studies. But the contributions of the anxiety, depression and stress as a whole to the NUD were not assessed. In this study, we wanted to show the associations of the anxiety, depression and stress levels with NUD. METHODS: This study was performed by case and control method from Aug. 1 to Sep. 7 at the outpatient department of Family Medicine and at the Health Management and Service department in Pusan Paik Hospital. The both groups were matched by sex and age. The case was defined who has three or more symptoms among nine upper gastrointestinal symtoms like dyspepsia, epigastric pain and anorexia etc. frequently or alwalys and who has no ulcer at the gastrofibroscope. The anxiety, depression, stress levels were measured by questionnaire which was validated by previous studies. The questionnaire was composed of Trait-STAI, Jung's Self Depression Scale(SDS), Modified BEPSI, and Grobal Assessment of Recent Stress(GARS) Scale. RESULTS: The total subjects were 136 persons(NUD group : 86 persons/control group : 86 persons). There were. significant differances in regularity of diet(P<0.001), levels of education(P=0.009), and history of medications(P<0.001) between two groups. The two group had higher scores than the control group in the depression score, anxiety score and modified BEPSI score(P<0.001). All items in GARS showed higher scores in NUD group than in control group(P<0.001). CONCLUSIONS: NUD group had higher degree of anxiety and depression than the control group. It seems that the NUD may have streeful status. When we encounter the NUD in outpatiet department, we had better consider the underlying psychogenic or stressful conditions.

9.The Beneficial Effect on the Early Lumbar Stabilization Exercise after Microdiscectomy.
Korean Journal of Spine 2009;6(1):6-10
OBJECTIVE: The purpose of this study was to investigate the effect of early 3-D lumbar stabilization exercise to patients with chronic lumbago after microdiscectomy. METHOD: From March 2006 to January 2008, 234 patients(male: 104, female: 130) who underwent lumbar microdis- cectomy were performed CENTAUR lumbar stabilization exercise at 7days postoperatively, CENTAUR was used to measure strength of stabilization muscle. RESULT: As a result after lumbar stabilization exercise for 8weeks, lumbar muscular strength increased by 24% averagely at 8 angles(0 degrees, +45 degrees, -45 degrees, +90 degrees, -90 degrees, +135 degrees, -135 degrees, 180 degrees;+ clockwise, - counterclockwise)(p<0.05). It was possible for the microdiscectomy patients to practice lumbar stabilization exercise at 7days postoperatively. CONCLUSION: The early lumbar stabilization exercise was good effect on the muscular strength after microdiscectomy.

BACKGROUND: Unilateral lung hyperinflation develops in lungs with asymmetric compliance, which can lead to vital instability. The aim of this study was to investigate the respiratory dynamics and the effect of airway diameter on the distribution of tidal volume during mechanical ventilation in a lung model with asymmetric compliance. METHODS: Three groups of lung models were designed to simulate lungs with a symmetric and asymmetric compliance. The lung model was composed of two test lungs, lung1 and lung2. The static compliance of lung1 in C15, C60, and C120 groups was manipulated to be 15, 60, and 120 ml/cmH₂O, respectively. Meanwhile, the static compliance of lung2 was fixed at 60 ml/cmH₂O. Respiratory variables were measured above (proximal measurement) and below (distal measurement) the model trachea. The lung model was mechanically ventilated, and the airway internal diameter (ID) was changed from 3 to 8 mm in 1-mm increments. RESULTS: The mean ± standard deviation ratio of volumes distributed to each lung (VL1/VL2) in airway ID 3, 4, 5, 6, 7, and 8 were in order, 0.10 ± 0.05, 0.11 ± 0.03, 0.12 ± 0.02, 0.12 ± 0.02, 0.12 ± 0.02, and 0.12 ± 0.02 in the C15 group; 1.05 ± 0.16, 1.01 ± 0.09, 1.00 ± 0.07, 0.97 ± 0.09, 0.96 ± 0.06, and 0.97 ± 0.08 in the C60 group; and 1.46 ± 0.18, 3.06 ± 0.41, 3.72 ± 0.37, 3.78 ± 0.47, 3.77 ± 0.45, and 3.78 ± 0.60 in the C120 group. The positive end-expiratory pressure (PEEP) of lung1 was significantly increased at airway ID 3 mm (1.65 cmH₂O) in the C15 group; at ID 3, 4, and 5 mm (2.21, 1.06, and 0.95 cmH₂O) in the C60 group; and ID 3, 4, and 5 mm (2.92, 1.84, and 1.41 cmH₂O) in the C120 group, compared to ID 8 mm (P < 0.05). CONCLUSIONS: In the C15 and C120 groups, the tidal volume was unevenly distributed to both lungs in a positive relationship with lung compliance. In the C120 group, the uneven distribution of tidal volume was improved when the airway ID was equal to or less than 4 mm, but a significant increase of PEEP was observed.
