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.

N/A Although bone scan is a highly sensitive test for detecting bone metastasis, its findings are often limited in specificity and cannot be used for assessing the bone marrow. Bone marrow scintigraphy may provide useful information but previous experience with radiolabelled colloid has been disappointing. Recently, 99mTc labeled anti-granulocyte rnonoclonal antibody (anti-NCA-95 MAb) has been introdueed as a new bone marrow imaging agent. To evaluate the usefulness of 99mTc anti-NCA MAb bone marrow scans for detecting skeietal metastasis, bone marrow scans of 44 malignant tumor patients were evaluated and compared with bone scan fmdings. Bone scan showed abnormal lesions in 26(59%) cases, and 18 of these patients also had an abnormal bone marrow scan. Seven of the 8 patients who had normal bone marrow scan despite bone scan lesions were confirmed to be free from metastasis. There was one case with a marrow defect despite normal bone scan but the presence of metastasis was not determined due to loss of follow up. Bone scan demonstrated a total of 64 lesions while bone marrow scan showed 38 lesions. Fifty percent (32/64) of the bone scan lesions had matching marrow defects while the rernaining 50% did not. Most of these non matched lesions were suggested to be nonspecific 1esions such as rib fractures or degenerative change. Meanwhile bone marrow scan was able to detect 6 new lesions not detected by bone scan, but metastasis in each lesion was not confirmed. Bone marrow scan was also helpful in assessing equivocal bone scan lesions to be of metastatic nature in 10 patients by demonstrating a matched marrow defect. Thus 99mTc anti-NCA MAb bone marrow scan can help exclude metastasis in patients with nonspecific bone scan lesions and may be able to detect metastatic lesions not seen with bone scan. It appears useful as a complementary study to bone scan in evaluating malignant tumor patients.

Edible flower means a flower that is good to eat is subject to either cooking or appetizing. In general, people eat edible flower as raw so that the loss of vitamin and inorganic are minimal. Edible flower is usually utilized as salad material or aromatic, decoration for jelly or cake and solid stuff in soup. Thus, decorating food by edible flower improves flavor, fragrance and appetite. Edible flower serves various purposes both east and west. In Korea, Edible flower is mainly subject to soup, cooked potherbs, frying, tea stuff, brewing and etc, whereas in Japan, its various usage covers cooked potherbs, pickle, sliced raw fish, frying, salad, jelly and decoration. On the other hand, Edible flower is used as numerous salad and tea stuff, condiment, roasting, meat, sweets and desserts in Western Hemisphere.

Objective : Since Korea has been known to be of the endemic area for hepatitis B virus(HBV) infection, vaccination for HBV has been recommended for all neonates in Korea. After starting vaccination in 1983, the change of sero-positivity of HBsAg and HBsAb is expected. This study was carried out to investigate the seropositive rate of hepatitis B virus surface antigen and antibody in high school freshmen students in Chungju-city. Methods and Materials : From 1998 to 2001, a total of 11,735 who were born in 1982 to 1986, were enrolled in this study. HBsAg and anti-HBs were tested by reversed passive hemagglutination and passive hemagglutination, respectively. Results : The study population was 11,735 students who were composed of 5,813 males (49.6%) and 5,914 females (50.4%). The HBsAg sero-positivity of male and female students was 3.25% (n=381) and 2.59% (n=153) respectively. The anti-HBs sero-positivity of male and female students was 62.2% (n=3,154) and 64.1% (n=2,969) respectively. There are significant difference observed in comparison of HBsAg and anti-HBs seropositivity according to sex (p<0.05). From 1982 to 1986 on birth year, anti-HBs sero-positivity has been increased significantly from 63.3% to 73.3%. But the change of HBsAg sero-positivity has not been changed significantly. Conclusions : As compared with previous studies of HBsAg and anti-HBs, the sero-positive rate of HBsAg has not been changed but that of HBsAb has been increased significantly. This result revealed that the effect of HBV vaccination program was successful.

The mechanism by which blastocysts implant to uterine endometrium has not been clearly understood. In the present study, the following question was investigated: how are hormonal levels changed and how is uterine endometrium morphologically changed? Results obtained are as follows: Concentrations of serum estradiol and progesterone were significantly increased on day 4 and 5 of pregnancy. Uterine concentrations of PGE and $PGE_{2a}$ were sharply increased on day 1 and maintained similar concentrations thereafter, reaching the maximum on day 5. Both prostaglandins (PGs) concentrations were gradually decreased thereafter. Furthermore, concentrations of PGs in implant sites were greater than those in non-implant sites. PBR (pontamine blue reaction) in uterine endometrium was positive on day 6 of pregnancy, indicating that vascular permeability was increased. Edema and changes in structure of cell components were pronounced in stroma where PBR was developed. Moreover, these were more prominent in implant sites than non-implant sites. These results suggest that uterine PGs as well as steroid hormones increase during implantation in rats and these hormones might be involved in the process of implantation by modulating vascular permeability and the fine structures of uterine endometrial cells.

폐동맥고혈압이 동반된 만성폐쇄성폐질환 환자에서 혈중 Brain Natriuretic Peptide, 폐동맥압 및 St. George Respiratory Questionnaire의 상관성과 안지 오텐신전환효소억제제 치료 효과

Background: Pulmonary hypertension is considered as a poor prognosis factor in patients with chronic obstructive pulmonary disease (COPD). There has been reported brain natriuretic peptide (pro-BNP) is related with increased right ventricular (RV) workloads. However, there are few studies that evaluate the relationship between BNP and pulmonary arterial pressure (PAP), RV function and St. George Respiratory Questionnaire (SGRQ) score in patients with COPD, and the effects of angiotensin converting enzyme inhibitor (ACEI) on these parameters. Methods: Pulmonary function test, echocardiography, blood BNP, and SGRQ score were evaluated in stabilized moderate degree COPD patients (FEV1/FVC<70%, 50%≤FEV1<80%) aged 45 years and over, without worsening of symptoms within recent 3 months. After treating with ramipril 10 mg for 3 months, the same evaluation was repeated. Results: Twenty-two patients were included in this study. BNP was significantly correlated with PAP (Pearson coefficient ρ=0.51, p=0.02), but not with RV ejection fraction (EF) and predicted FEV1%. The values for predicted FEV1% showed significant correlation with SGRQ total score and activity score, but not with BNP or PAP. After ramipril treatment, PAP showed significant decrease (42.8±8.1vs.34.5±4.5 mm Hg p=0.0003), tricuspid annular plane systolic excursion significant increase (21.5±3.3vs.22.7±3.1 mm p=0.009). BNP showed a tendency to decrease without statistical significance (40.8±59.6vs.18.0±9.1 pg/mL p=0.55). SGRQ scores showed no significant change. Conclusion: BNP showed significant correlation with resting PAP, which means BNP could be used as markers for pulmonary hypertension. Treatment with ACEI didn`t show significant change in the Level of BNP, while pulmonary hypertension and RV function were improved.

본 연구는 임신중에 MAM이 투여된 어미에서 태어난 새끼들이 도피검사에서 수행장애를 나타내는가를 검토해 보고자 하였다. 피험동물의 반수는 변동간격계획 60초에 따라 6초간 지속되는 60회의 도피불가능한 전기충격(1.0mA-900V, DC)을 받았고, 나머지 동물들은 충격을 받지 않았다. 도피검사는 최초의 스트레스회기가 종료된 24시간 후에 실시되었다. 도피불가한 전기충격에 대한 노출경험은 전기충격을 도피하는 과제에서 반응시간의 증가를 초래했다. 그러나 이런 충격효과는 MAM 처치동물에서는 현저하지 않았다. 단순구금된 MAM 처치흰뒤들도 전기충격을 받은 MAM처치 흰쥐와 통제군의 흰쥐만큼 도피수행의 결함을 나타내었다. 이런 결과는 MAM처치동물들이 비교적 정도가 낮은 스트레스에 대해서도 민감하게 반능할 가능성을 시사해 준다. The effect of prenatal treament of rats with methylazowymethanol(MAM) on the deficits of escape behavior was evaluated. Half the rats received 60 inescapable shocks of 1.0mA (900V, DC) of 6s duration at variable intervals of 60s. The other restrained animals did not receive any shock. Escape testeing was conducted 24h after termination of the initial stress session. The exposure to inescapable shock subsequently increased the latency to escape from shock, but the degree of icrease was less prounced in MAM-treated animals than in saline treated controls. The performance of nonshock rats with MAM treatment exhibited escape deficits comparable to preshocked rats. This results suggested that the MAM rats are sensitive to the moderate levels of stress.

We report the case of a 34-year-old woman with autosomal dominant polycystic kidney disease associated with primary aldosteronism due to left adrenal adenoma. Although autosomal dominant polycystic kidney disease could mask hypokalemia and hypertension, refractory hypertension and hypokalemia were the clues that led to this diagnosis. The diagnosis of primary hyperaldosteronism was based on the presence of hypokalemia with excessive urinary potassium excretion and characteristic hormonal changes. Under laparoscopy, left adrenalectomy was performed. After surgery, plasma renin activity, plasma aldosterone titer, and serum potassium level normalized with only partial correction of the blood pressure. This could be explained by the persisting underlying polycystic kidney disease. We conclude that extrarenal causes in a hypertensive and hypokalemic patient with polycystic kidney disease may be ruled out.
