N/A Dipyridamole is an agent that may be used to noninvasively evaluate coronary artery disease. The effect of dipyridamole infusion its generally related to its induced peripheral vasodilatory effect. In normal person, heart rate is generally increased slightly while blood pressure decrease, but the achieved double product and related myocardial oxygen consumption have no significant change. The purpose of this study is to examine the effect and side effect of dipyridamole, and to compare different response to dipyridamole among the patients. We evaluated 847 patients who underwent dipyridamole stress myocardial SPECT. 93.6% of them had induced hypotension 0.9% showed no change of blood pressure, 5.5% had increased blood pressure 8.3% had no change of pulse rate more than 10% of basal pulse rate. Among diabetes, 16.9% was not change of pulse rate, 6.7% in non-diabetes. There was no significant correlation between age and rate pressure product rest(RPPr), in patients without perfusion defects on SPECT(y=7.1x+48.4r=0.13 p>0.01). As increasing age, RPPs/RPPr was declined(y=-11.6x+68.9 r=0.17 p〈0.01), similar results were obtained in patients with perfusion defect. The size of perfusion defect on myocardial SPECT have no correlation between RPPr and RPPs/RPPr. The side effects of dipyridamole included chest pain and chest tightness, headache, abdominal pain, dizzness, nausea, and dyspnea. As increasing age, dipyridamole-induced cardiac work at rest was increased, cardiac response to dipyridamole was decreased.

Choi, Chang‐,Hyung,Jeong, Jae‐,Min,Kang, Sung‐,Min,Lee, Chang‐,Soo,Lee, Jinkee WILEY‐VCH Verlag 2012 ADVANCED MATERIALS Vol.24 No.37

<P>A novel synthesis method for microspheres using micromolds based on the Laplace pressure difference is presented by Jinkee Lee, Chang‐Soo Lee, and co‐workers on page 5078. This simple micromolding technique makes it possible to synthesize highly monodispersed microspheres with the flexibility of various reaction schemes, such as photopolymerization, sol‐gel reactions, and colloidal assembly. This method is promising for the mass production of various sizes of monodispersed microspheres without the need for complicated control of fluids. </P>

N/A Objectives: There is little information on the imbalance of electrolyte and acid-base metabolism associated with gastric lavage in acute drug intoxication patients. This study was aimed to analyze the acid-base and electrolyte abnormalities associated with gastric lavage in acute drug intoxication patients. Methods: We studied 24 acute drug intoxication patients who had performed gastric lavage with 10 liters of 0.9% NaC1. Electrolyte parameters and arterial blood gas analysis were carried out before and after gastric lavage. Results: After gastric lavage, acidosis was reduced in general. But there was no significant change in pH (7.34±0.02 vs. 7.38±0.15, p=NS). In acid-base balance, the mixed form of metabolic acidosis and respiratory acidosis was reduced from 7 to 2 cases, and the simple form of respiratory acidosis was reduced from 3 to 1 case. In contrast, normal form was increased from 5 to 7 cases and the simple form of metabolic acidosis was increased from 2 to 6 cases. In electrolyte parameters, serum sodium was reduced significantly (145±1.0 mEq/L vs. 141±0.8 mEq/L, p<0.01), but there was no case of significant hyponatremia (<135mEq/L). Bicarbonate level (20±1.1 mEq/L vs. 22±0.9 mEq/L, p< 0.05) and anion gap (19±1.6 mB vs. 13±1.3 mEq/L, p< 0.01) showed significant change. But, blood levels of potassium (3.6±0.1 mEq/L vs. 3.8±0.1 mEq/L, p=NS), chloride (106±0.6 mEq/L vs. 106±0.6 mEq/L, p=NS) and F'aCO2 (36±1.mmHg vs. 37±1.5 mmHg, p=NS) were no significant change before and after gastric lavage. Conclusions: Gastric lavage with 10 liters of 0.9% NaC1 in acute drug intoxication patients did not show clinically significant changes in electrolytes and acid-base balance.

This study is to evaluate clinical and arthroscopic second-look results of arthroscopic repairs of posterior root tears of medial meniscus which may cause loss of circumferential hoop tension and extrusion of meniscus. From October 2006 to May 2009, fifty-eight patients (59 knees) underwent arthroscopic pull-out repairs. Clinical results were evaluated using Hospital for Special Surgery (HSS) score and International Knee Documentation Committee (IKDC) score for 12-month follow-up. Second-look arthroscopy was done to evaluate meniscal healing in 21 cases. Magnetic resonance imaging (MRI) was performed to assess status of repaired meniscus and tibial tunnel position in 9 patients. Average preoperative HSS score and IKDC score of 59 cases were 69.5 and 36.0, respectively. Average postoperative HSS score and IKDC score of 59 cases had been changed into 90.3 (p<0.001) and 66.8 (p<0.001), respectively. Second-look arthroscopies revealed complete or incomplete healing except one case. Two patients showed increased one grade according to the Kellgren-Lawrence radiologic classification system and others showed no change. Of 9 patients who performed MRI, six patients showed complete healing. The average position of tibial tunnel was 4.8 mm anterior and 5.7 mm medial to center of posterior cruciate ligament. Arthroscopic pull-out repair technique using transtibial tunnel seems to be simple and effective procedure for posterior root tear of medial meniscus. Further evaluation of arthroscopic repair of posterior root tear of medial meniscus should be needed to prove the effectiveness on the prevention of osteoarthritis of knee.

N/A Background: According to the rapid changes in social environment such as increasing alcohol consumption and the marked improvement in diagnostic technique, we expect that there have been major changes in various aspects of acute pancreatitis during the recent 12 years in Korea. Methods: The medical records of 317 patients with acute pancreatitis diagnosed from 1980 through 1992 were reviewed about clinical, laboratory and radiological findings in the three different time period. Results: 1) There has been an increasing incidence in male sex about three folds. 2) There has been an increasing trends in the duration of hospitalization. 3) A significant increase was observed in the proportion of patients with alcoholic pancreatitis in the three different time period; 26.9%, 45.7%, 50.7% respectively. 4) The complication rates have been slightly increased in the three different time period; 46.3%, 47.1%, 59.1% respectively. But, the type of complications has not been changed. 5) There is increasing severity in non-gallstone group, but no significant differences in gallstone group. There is a declining trends in the number of patients with muld severity index, but increasing trend in the number of patients with moderate severity index in non-gallstone group. 6) There was no significant differences in mortality rate. Conclusions: There has been major changes in the etiology ans severity of acute pancreatitis from 1980 through 1992. Especially, significant increase in the proportion of patients with alcoholic pancreatitis was observed in the three differnt time period. These results might be due to socioeconomic changes.

Sarcoidosis is a multi-organ disease with various clinical manifestations. The lung is the most common site of manifestation; however, unusual findings may delay the correct diagnosis of sarcoidosis. Here we report a case of 32-year-old man with 4-month history of neck mass. Radiological findings revealed multiple pulmonary parenchymal nodules, with initial biopsy results of his neck lymph node showing chronic granuloma with focal necrosis. The patient was treated with anti-tuberculosis medications, but the size of the nodules did not change. Biopsy was performed from one of his pulmonary nodules, which revealed chronic granuloma without necrosis. Therefore, the patient was diagnosed with sarcoidosis. We present a case of sarcoidosis with multiple lung parenchymal nodules that is uncommon in Korea, with an aim to alert physicians of such unusual presentations.

The usefulness of a nondepolarizing muscle relaxant for endotracheal intubation is limited by its relatively slow onset of neuromuscular block compared to that achieved with succinylcholine. Several attempts have been made to produce a more rapid onset of muscle relaxation for endotracheal intubation. A large dose of nondepoarizing muscle relaxant may produce rapid onset but cauae undesirable side effects and a prolonged duration of neuromuscular block. The authors observed the degree of vocal cord relaxation and intubation condition 2 minutes after administration of atracurium and measured changes in mean arterial blood pressure and heart rate at the time of arrival in the operating room, just before abministration of atracurium, 2minutes after administration, and 5mins after intubation. The 40 of patients in this observation were divided into four groups. Group 1; 10patients, received 0.3 mg/kg of atracurium Group 2; 10patients, received 0.4 mg/kg of atracurium Group 3; 10patients, received 0.5 mg/kg of atracurium Group 4; 10patients, received 0.6 mg/kg of atracurium The results were as follows; 1) There were better intubating conditions in Group 3 and 4 than in Group 1 and 2(p$lt;0.001). 2) Mean arterial blood pressure and heart rate did not change significantly after administration of atracurium in all four groups. From the above results we conclude that 0.5~0.6 mg/kg of atracurium provides satisfactory intubation condition 2 minutes after administration without hemodynamic changes.

Background: Subclinical hypothyroidism(SCH) is a common biochemical abnormality which can be found in routine screening tests of thyroid function. We are increasingly faced with the question of whether its an indication for thyroxine replacement therapy. The effect of thyroxine replacement on lipid profile in SCH has aroused a great interest because of an association of overt hypothyroidism(OVH) with hyperlipidemia and increased risk of coronary artery disease. Method: We prospectively evaluated the changes in lipids and apoproteins before and after thyroxine replacement therapy in 23 patients with SCH and in 37 patients with OVH. We measured serum total cholesterol and triglyceride using autoanalyzer, high density lipoprotein(HDL) chole-sterol by dextran sulfate method, Apo A1 and Apo B by immunonephelometric assay. Results: Thyroxine replacement therapy significantly decreased total cholesterol, low density lipoprotein(LDL) cholesterol and apo B levels, but did not affect the level of triglyceride, HDL cholesterol or apo AI in patients with OVH. In SCH, thyroxine replacement therapy with the doses to normalize serum TSH concentrations also decreased significantly the level of cholesterol and LDL cholesterol albeit apo B levels did not change. Moreover, in most of patients with OVH (11 of 12) and in all of patients with SCH(5 of 5) who had had hyperchlesterolemia before treatment, thyroxine replament normalized their cholesterol and LDL cholesterol levels. Conclusion: In regard to the beneficial changes in blood lipid levels, patients with SCH should be treated, especially in cases who have other risk factors for the development of atherosclerosis. If thyroxine replacement only will reduce the incidence of coronary artery disease in SCH remains to be elucidated by long-term prospective studies(J Kor Soc Endocrinol 11:41-51, 1996).

The characteristics of stroke slightly vary as time changes. To compare the characteristics of stroke between the 1980s and 1990s we investigated the clinical records of stroke patients in 1987 and 1994. The subjects of this study consisted of the 1971 patients who were admitted as stroke patients to the Kyunghee University Oriental Medicine Hospital during these two years. There were 1092 stroke patients admitted from May, 1987 to April, 1988 and 879 stroke patients admitted between May, 1994 and April, 1995. The results were as follows. The frequency of cerebral infarction was 77.9% in 1987 and 79.9% in 1994. The male to female ratio of stroke patients was 1.4:1 in 1987 and 1.6:1 in 1994. The occurrence rate of stroke in both 1987 and 1994 were highest in patients in their 60s, followed by those in their 50s, 70s and older, in their 40s, and finally their 30s and below. We especially found that the rate of patients in their 70s and over increased from 17.8% in 1987 to 25.3% in 1994, which was remarkable in cerebral infarction patients. The most common disease preceding a stroke was hypertension, followed by heart disease and diabetes in 1987, and in 1994 hypertension was the most common, followed by diabetes and heart disease. The rate of recurrence among cerebral hemorrhage, that was 12% in 1987 and 24.7% in 1994. The most frequent complications of stroke in 1987 and 1994 were pneumonia and urinary tract infection, respectively. The prescriptions used most frequently during admission were Chungpaesagan-tang followed by Sunghyangjungki-san, Yangyeksanhwa-tang etc. in both 1987 and 1994. When patients were getting better, prescriptions for invigorating Qi and enriching the blood(補氣血) were used more frequently. In conclusion, the most remarkable change of stroke patients from 1987 to 1994 was an increase in occupancy rate of aged patients, especially those in their 70s and older. So we suggest that more research are needed on the stroke of aged man, along with many other subjects on stroke.
