This study is a methodical research to develop a health behavior assessment scale for patients with rheumatoid arthritis, and to test the validity and reliability of the instrument. The research procedure was as follows; 1) The first step was to develop conceptual framework based on a comprehensive review of the literature, in-depth interviews patients with rheumatoid arthritis. This conceptual framework was organized in eight dimensions; pain management, exercise, rest, diet control, active committment, self-management, positive thinking, interpersonal maintenance. Initially 56 items were selected from 164 statement. 2) These items were reviewed by panel of eight specialists and the Index of Content validity (CVI) was calculated, and forty six items were selected which met more than 70% on the CVI. 3) 174 rheumatoid arthritis pateints were interviewed, and data was gathered from Jan. 25 to Feb. 18, 1999 for test reliabilities and validities of the scale. The item analysis was carried out and 40 items were selected. Factor analysis by varimax rotation was carried out to test construct validity. The internal consistency by chronbach's alpha was calculated. The findings were as follows; 1) Item analysis and factor analysis were carried out to test the validity of the health behavior assessment scale. The item analysis was based on the corrected item`s to total correlation coefficient (.30 or more), and information about the alpha estimate. However, this was only if this item was deleted from the scale. As a result of the item analysis, forty items were selected. Thirty items were selected by a initial factor analysis by varimax rotation, and ten items were deleted because of factor complexity. In the secondary factor analysis, eight factors were labled as 'positive thinking', 'exercise', 'rest', 'pain management', 'active committment', 'self-management', 'diet control', and 'interpersonal maintenance', each similar with the conceptual framework. 2) Chronbach's alpha coefficient to test reliability of the scale was. 903 for total the thirty items. The Scale for assessing health behavior developed in this study was identified to be a tool with a high degree of reliability and validity. Therefore this scale can be effectively utilized for assessment in the health behaviors of the patients with rheumatoid arthritis.

OBJECTIVE: Peripartum emergency cesarean hysterectomy of 28 cases at our hospital for 10years were reviewed that the clinical indication, history, and annual incidence change. METHODS: A retrospective descriptive analysis from January, 1988 to December, 1997 was carried out. RESULTS: There were 28 cases of emergency cesarean hysterectomy identified during this period among total 24, 689 deliveries. The annual incidence of emergency cesarean hysterectomy was significantly declined statistically(p<0.005). Cesarean hysterectomy was performed in 20 of 6, 671 cesarean section(0.30%) and in 8 of 18, 018 vaginal deliveries(0.04%), so more frequently after cesarean section than vaginal delivery. The cesarean hysterectomy rate was more frequent in multiparous women(0, 22%) than in nulliparous women(0, 02%). The most common indication of cesarean hysterectomy was 13 cases of uterine atony(46%), followed by 5 cases uterine rupture(18%), 5 cases of placenta previa with placenta accreta(18%), 3 cases of placenta previa(11%), 2 cases of uterine myoma(7%). No significant difference in length of operating time, amount of blood loss and operative complications were found between total abdominal hysterectomy and subtotal hysterectomy. The all patient who had cesarean hysterectomy recieved from 1200ml to 15840ml of blood transfusion with a mean of 3673ml. In aspect of fetal outcome, 3 cases of FDIU(Fetal death in utero) in uterine rupture and 1 case of stillbirth in preterm were found. The maternal complications were wound disruption, DIC, wound hematoma, ureter injury, vaginal stump bleeding, UTI(Urinary tract infection) and retroperitoneal bleeding, CONCLUSION: We conclude that the incidence of emergency cesarean hysterectomy declined with prediction of antenatal risk factor, preparing of sufficient fresh blood, prophylactic antibiotics, vigorous uterotonics and close observation after delivery.

BACKGROUND: Induction of anesthesia with propofol commonly associated with reduction in systemic arterial pressure, especially in elderly and high risk patients. This reduction is influenced by the dose and rate of propofol injection. The aim of this study was to examine the effect of different injection rate of propofol on vital signs, dose requirement and induction time during induction period. METHODS: Unpremedicated one hundred and twenty ASA physical status I and II patients aged 20~60 years scheduled for elective surgery were randomly allocated into one of four (150, 300, 600, 1200 ml/hr) groups according to speed of injection of propofol during induction period. Loss of verbal contact was taken as the end-point of induction. Vital signs, SpO2, dose requirement of propofol and induction time were checked. RESULTS: As the injection rate of propofol became slower, there were significant reduction in induction dose and increase in induction time (p<0.05). For example, induction dose and time were 1.82 mg/kg, 223 +/- 58 sec in 150 ml/hr group and 3.14 mg/kg, 50 +/- 11 sec in 1200 ml/hr group, respectively. Also, decrease in systolic and diastolic pressure were less marked at lower injection rates. CONCLUSIONS: Slower injection of propofol produces less vital sign changes and dose requirement for the induction of anesthesia.

BACKGROUND: Reactive oxygen species (ROS) induce lipid peroxidation and tissue damage in the isolated rabbit thoracic aorta. The aim of this study was to explore the influence of the propofol and midazolam against ROS in the isolated rabbit thoracic aortic endothelium. METHODS: Eighteen white male rabbits (weighing 2.0-2.5 kg) were used. The thoracic aorta was dissected free and cut into rings (3-4 mm) and then suspended in a organ bath filled with 10 ml Krebs solution bubbled with 5% CO2 95% O2 at 37 degrees C. Aortic rings were then equilibrated for 90 min, and a resting tension of 1.5 g was applied. The Krebs solution was changed every 15 min. Isometric tension was recorded with transducer coupled to a data acqusition system (Biopac Inc. USA) on a PC. After precontraction with norepinephrine (NE, 10(-6)M), changes in tension were measured following the cumulative administration of acetylcholine (ACh 3x10(-7), 10(-6) and 3x10(-6)M) and nitroglycerin (NTG, 10(-5)M). Data are expressed as percentage of the 10 5 M NTG-induced relaxation (ACh/NTG). The ACh/NTG, before and after electrolysis were defined as the control and the experimental groups. The aortic rings were pretreated with propofol (3x10(-5), 10(-4), 3x10(-4) and 5.7x10(-4) M, n = 8, 10, 15, 13), midazolam (10(-4)M, n = 7), catalase (1,000 U/ml, n = 12), mannitol (3x10(-4)M, n = 5) or not pretreated group (Free, n = 6). After 30 minutes, the aortic rings were exposed to ROS generated by electrolysis (DC 9 V, 20 mA, aortic rings 1 cm away from electrode) in Krebs solution for 2 minutes, which was then changed for physiologic buffered salt solution. The aortic rings were precontracted with NE and vasorelaxation was induced with ACh and NTG at the above mentioned concentrations. RESULTS: Propofol produced vasorelaxation of NE-precontracted thoracic aorta in a dose-dependent fashion in all groups of propofol (3x10(-5), 10(-4), 3x10(-4) and 5.7x10(-4)M) even after ROS attack (P < 0.05 vs control value). Catalase produced vasorelaxation after ROS attack (P < 0.05 vs control value).On the other hand, ACh-induced significant endothelium-dependent vasorelaxation were not observed in the midazolam or mannitol pretreated group or the non-pretreated group (P <0.05 vs control group). CONCLUSIONS: These findings suggest that propofol and catalase preserve ACh induced endothelium-dependent vasorelaxation and that propofol has a concentration dependent ROS scavenging effect like catalase.

Fetal teratomas rarely complicate pregnancy,having an incidance of only 20,000:1 to 40,000:1 of live births. Overthere, cervical teratomas are rare and accounts for only 5.5% of all neonatal teratomas. We have experienced a large cervical immature teratoma and present this case with a brief review of literatures.

The authors have analysed 39 rheumatoid wrists in 25 rheumatoid patients, who underwent vsrious surgeries including arthroscopic and open synovectomy, partial and total arthrodesis and total wrist arthroplasty at the department of orthopaedic surgery, St. Mary's Hospital from November 1985 to April 1988, and the effect of eaeh surgery on the wrist function and proper time of operation are discussed. The results were as follows; 1. The patients who were classified as a classical rheumatoid arthritis according to the ARA criteria were four males and twenty-one females, with a mean age of 43 yesrs, and the functional capacity of the patients before operation was graded in III for twenty-threeand in IV for two patients. 2. Out of 25 patients (39 wrists), 14 patients are in bilateral and II patients in unilateral involvement. The synovectomy in 13 wrists, arthrodesis in 24 wrists and total joint replacement in 2 wrists were performed and followed them for average 17 months after operation. 3. The synovectomy were done for 13 wrists in grade II and III according to the classification of rheumstoid arthritis by radiology(3). There were two cases of recurrence in the cases of synovectomy, but not in replacement and arthrodesis. 4. The arthrodesis of wrist was performed for 24 wrists-bilateral arthrodesis in 3 patient (6 wrists) and unilateral fusion in 18 patients. For 4 cases out of 24 cases of wrist arthrodesis, the second and third carpo-metacsrpal joints were fused simultaneously. 5. Protek total wrist arthroplasty was done in 2 cases snd followed them for more than9 months with relatively good clinical results. Finally, it is our beliefs for rheumatoid wrists that surgery is often indicated to control the various wrist problems, early synovectomy is strongly indicated, and partial wrist fusion has proven to be effective in patients with moderate destruction, deformity and pain, but the total wrist arthrodesis and arthroplasty is still in controversy. The proper surgery for rheumatoid wrist should be determined by the clinical severity of disease and radiological changes of wrist.

BACKGROUND: When used to reverse the anticoagulant effect of heparin, protamine administration after cardiovascular bypass often can lead to systemic hypotension. During the reversal of heparin-induced anticoagulation, the effects of protamine on both a heparin-protamine complex and free protamine on the cardiovascular system should be considered. METHOD: To determine whether the hypotensive effect of heparin-protamine and/or protamine could be caused by endothelium-dependent and-independent component, we studied rings of the arotic arteries in rats suspended in organ chambers containing Tris Tyrode solution at 37oC and 100% O2. Arterial rings with or without endothelium were contracted with 40 mM KCl or 3 +/- 10-6M phenylephrine and then exposed to increasing concentrations of protamine (final organ bath concentration, 40~400 g/ml) both in the absence and presence of heparin (200 U/ml). RESULTS: Protamine induced concentration-dependent relaxation in arterial rings with endothelium, which were significantly greater than in rings without endothelium. The endothelium-dependent relaxation induced by protamine was inhibited by NG-monomethyl-L-arginine (L-NMMA) (10-5M) pretreatment, but was not inhibited by indomethacin (3x10-6M) pretreatment on rings with endothelium. Furthermore, the contractile inhibition was enhanced by superoxide dismutase (100 U/ml). Also, such vasodilating actions were not influenced in the presence of heparin (200 U/ml). In endothelium-denuded strips, protamine (400ug/ml) inhibited Ca++ induced contraction, which was evoked in Ca++-free solution containing 40 mM K+, and also inhibited the norepinephrine (NE)-induced contraction. Protamine inhibited on the NE-induced contraction, but not the caffein-induced contration in Ca++ free, 2 mM EGTA solution. Also, such inhibition of contracions were not inluenced in the presence of heparin (40 U/ml). CONCLUSION: This study demonstrates that protamine (in the presence or absence of heparin) acts on endothelial cell receptors to stimulate the production of nitric oxide and inhibits both Ca++-influx and the NE-induced Ca++ release from intracellular stores.

The Shy-Drager syndrome is a very rare chronic progressive disease characterised by autonomic failure and multiple system atropy. The main clinical manifestations of this syndrome are orthostatic hypotension, urinary and bowel dysfunction, impaired sexual potency and parkinsonean symptoms. A key in the management of anesthesia is the maintenance of cardiovascular atability. These patient are suffered from defective baroreceptor regulation of the blood pressure as a result of autonomic failure. We report a successful epidural anesthesia for vwicolithotomy in a female patient with Shy-Drager syndrome.
