As the Tc-99m-MIBI myocardial SPECT demonstrated wide application in the diagnosis of myocardial function, the quantitative and severity-dependent information is currently re quired. In this study, we proposed a computerized method for scoring the fixed defects in terms of extent-weighted severity and for identifying the reversibility in ischemic regions. At the first stage of this method, the transverse slices were reconstructed with 0.4 Nyquist freq. and order 5 Butterworth filter. From the oblique/sagittal slices, maximal count per pixel circumferential profiles were extracted for each sector, and then stress/redist. polar maps were normalized and plotted. For reversibility, the stress polar map was subtracted from the de-layed image and positive-valued pixels were categorized into three grades. The extent-weight-ed severity scores were calculated using the assigned grades and their number of pixels. This procedure was done automatically and the reversibility and severity scores were produced for each of the coronary territories (LAD, RCA, LCX) or any combination of these. Clinical ap-plication has shown that the changes In reversibility scores after PTCA were correlated linearly with the pre PTCA scores(r>0.8) in postinfarct cases as well as in angina, and severity scores of persistent defects in stress/rest SPECT study matched to the regional ejection fraction and visual analysis of regional wall motion of gated blood pool scan(r>0.6). We conclude that the computerized severity scoring method for the analysis of myocardial SPECT could be useful in the assessment of the myocardial ischemia and fixed defect.

Purpose : The aim of this study was to develop a quality of life scale for children on chronic peritoneal dialysis(QOL-CPD). Methods : Thirty children on chronic PD at Seoul National University Children's Hospital participated. A healthy control group included 47 elementary school children. Other patients groups are 32 children from the department of pediatric orthopedics and 28 children from the department of child psychiatry. The age range of all children was 7 to 16 years. Preliminary items of the QOL-CPD were developed and administered along with the Korean version of the Children's Depression Inventory(CDI) to all children. Results : The final QOL-CPD was constructed by excluding those items with a factor loading of less than .20, and the principal axis factor analysis was performed again. The QOLCPD demonstrated a good internal consistency with a value of .87. The dialysis and childpsychiatric groups showed significantly lower QOL scores compared to the healthy control group. In addition, the dialysis and child-psychiatric groups showed greater difficulties on physical and academic functions. For the CDI, the PD group showed a mild level of depression. Conclusion : The results of this study demonstrate the clinical utility of a newly developed self-report QOL scale specific for children on chronic PD.

Background This paper discusses the treatment protocol for patients with frostbite. Methods We performed a retrospective analysis of a series of 17 patients with second- and higher-degree frostbite who had been treated at our medical institution between 2010 and 2012. Results Our clinical series of patients (n=17) included 13 men and four women, whose mean age was $42.4{\pm}11.6$ years (range, 22-67 years). The sites of injury include the foot in six patients (35.3%), the hand in six patients (35.3%) and the facial region in five patients (29.4%). Seven patients with second-degree frostbite were completely cured with only conservative treatment during a mean period of $12.7{\pm}3.3$ days (range, 8-16 days). Of the five patients with third-degree frostbite, two underwent skin grafting following debridement, and the remaining three achieved a complete cure with conservative treatment during a mean period of $35{\pm}4.3$ days (range, 29-39 days). Five patients with fourth-degree frostbite were treated with surgical procedures including amputation. Conclusions With the appropriate conservative management in the early stage of onset, surgeons should decide on surgery after waiting for a sufficient period of time until the demarcation of the wound. Continuous management of patients is also needed to achieve functional recovery after a complete cure has been achieved. This should also be accompanied by patient education for the avoidance of re-exposure to cold environments.

With advancement of the medical imaging technology, the dynamic pelvic MRI (magnetic resonance imaging) has been introduced and used for dynamic MR defecography to improved diagnosis of the patients. At the early stage of its use, it was mostly used to diagnose enterocele or cystocele, then its use was extended to diagnose the organ prolapse and other dysfunctional pelvis organs. There now have been many reports of other diseases such as the functional constipation and others. This paper introduces the pelvis MRI and the dynamic MR defecography and reports the future trend in their clinical applications. Until recently, the studies with pelvic MRI were mostly focused on observing the movement of the pelvis in the supine position. Yang and 26 others reported good result in observing the patients with the pelvic organ prolapse by using the pubococcygeal line as the anatomical index. Using the fast gradient recalled acquisition (fast GRASS), they compared cystocoele, genitourinary prolapse, enterocoele and rectocoele with the control group. Kruyt et al. observed the posterior compartment and reported that MRI was more helpful than the fluoroscopy. Healy et al. applied the dynamic MRI test on the patients with constipation or incontinence as well as the control group without those symptoms. Since then, MRI technology has further advance by Lienemann, who was able to attain the more detailed images using the fast T2 weighted turbo spin echo technology, and others. If its limitation in diagnosing intussusception and the like, since the observation can be made only from the supine position, can be overcome with open MR or others, it is envisages that the method can eventually replace the radiological defecography.

Aortic aneurysm has poor prognosis and high mortality, but the incidence of aortic aneurysm is in increasing state. From July, 1986 to July, 1996, we operated on 25 patients with aortic aneurysm and analysed the clinical results and relations between the duration from symptoms onset to operation(Sx-Op), the duration from admission to operation(Adm-Op), preoperative blood pressure, preoperative heart rate and postoperative mortality, retrospectively. The patients were classified as dissecting aneurysm(10 cases), abdominal aortic aneurysm(9 cases), Marfan's syndrome(3 cases), descending thoracic aortic aneurysm(3 cases). The operative technique were graft interposition in 17 cases, Bentall's operation in 4 cases, aneurysm bypass in 2 cases, and wrapping of aorta in 2 cases. Seven patients died of several causes, bleeding in 5 cases, acute renal failure in 1 case and respiratory failure in another one case. Before 1992, the early stage of operation, 6 mortality among 14 operated patients occurred, and after then 1 mortality among 11 operated patients occurred. Eighteen survivors were followed up from 1 to 118 months(mean 50.6 months), and total follow up was 911 patient-months. During the follow up period one patient died of melena 30 months after operation. The other patients did not complain chest pain or dyspnea. The surgical mortality was improved in the late period, and the major cause of death was intraoperative or postoperative bleeding. The Sx-Op duration, the Adm-Op duration, preoperative blood pressure and preoperative heart rate were proven to have no statistical relations with postoperative mortality.

Objectives This study investigated the effect of purified safflower (Carthamus tinctorius Linne) and safflower seed (Carthamus tinctorius L. seed; CS) extract, using hot water and ethanol extract methods , on the osteogenic differentiation of MC3T3E1 cells.Methods The safflower and safflower seed were extracted with hot water and ethanol. The samples were concentrated by a rotary evaporator and then freeze-dried using a freeze-dryer. The MC3T3E1 cells were propagated and maintained in DMEM (Gibco) containing 10% FBS and a 1% antibiotic antimycotic solution. To induce osteogenic differentiation, the cells were treated for 14 days with DMEM with 10 mM β-glycerophosphate and 50 μM ascorbic acid. Extract doses were confirmed by the results of an MTT assay, and treatment of the extracts was performed in a differentiation medium every two days. The ALP staining and activity were tested after osteogenic differentiation for five days, and after 14 days, osteogenic differentiation was determined by alizarin red S staining. The mRNA expressions of osteogenic-related genes were quantified using quantitative real-time PCR.Results In the results of the MTT assay, all concentrations of safflower extracts had no toxicity in the MC3T3El cells. But in the groups of 100 ng/ml and 200 ng/ml concentrations of safflower seed extracts, the cell viability was significantly reduced by up to 40-50%. So we fixed the treatment concentration of the extract at 50 ng/ml. In the ALP and alizarin red S staining, all extract groups increased osteogenic differentiation compared with the control group. The water-safflower extract group showed the highest mRNA level of Alp, Runx2, and Dlx5 genes. The mRNA level of Ocn, an osteogenic gene related to late-stage differentiation, in the ethanol-safflower extract group increased the mineralization more significantly than in other groups.Conclusions These data suggest that the extract of safflower increases the osteoblastic differentiation activates of MC3T3E1 cells like the extract of safflower seed. The water-extract and ethanol-extract of safflower have effects on different stages of osteogenesis in MC3T3El. Not only safflower seed but also safflower will be useful therapeutic reagents for age-associated chronic diseases such as osteoporosis.

Glycogen storage disease (GSD) type Ia is rare inborn metabolic disorder, caused by glucose-6-phosphatase deficiency. It characterized by hepatomegaly, hypoglycemia, lactic acidosis, hypertriglyceridemia, and hyperuricemia and it is usually manifested in the infantile period. In addition, it is also associated with growth failure, pubertal delay, anemia, platelet dysfunction, osteopenia, and pulmonary hypertension. Hepatocellular adenoma and renal dysfunction are frequent late complications. Delayed diagnosis and inappropriate therapy lead to many complications such as growth failure, osteoporosis, refractory gout, renal failure, hepatocellular carcinoma (HCC), and pulmonary hypertension. Here, two Korean sisters diagnosed with GSD Ia, aged 33 and 36 respectively, were described and compared to recent articles about four adults with late diagnosis of GSD Ia. One sister had typical manifestations of GSD Ia including short stature (height, 145 cm), multiple hepatic adenoma, chronic kidney disease stage IV, and severe osteoporosis, whereas the older sister had normal stature (162 cm), one tiny hepatic nodule, and normal renal function. Direct sequencing of G6PC in two sisters identified a homozygous splicing mutation, c.645G>T, which is a prevalent mutation in Korea. Interestingly, our cases and four adults from recent reports had asymptomatic mild hypoglycemia and various manifestations including renal failure, HCC, fatty liver, or uncontrolled hyperlipidemia. These adult cases represent not only heterogenous phenotype to genotype within family members with GSD Ia but also long-term complications such as gouty arthritis, renal failure, and osteoporosis in untreated adult GSD Ia patients. In addition, lactic academia and hypertriglyceridemia are good markers of GSD Ia to distinguish from metabolic disease.

The causes of stroke are presumed hypertension, atherosclerosis,. cardiac disease, diabetes mellitus and old age and risk factors of stroke are suggested hypertension, hyperlipidemia. obesity, smoking and drinking etc. Especilly, hypertension is one of the most important cause and risk factor of stroke, therfore without therapy hypertension leads to stroke. The frequence of hypertension is significantly higher in hemorrhage patients of intracranial hemorrhage and subarachnoid hemorrhage. Antihypertensive therapy has an impact not only on the primary prevention of stroke but also on stroke recurrence and the declining of stroke motality has been attributed to the widespread availability and use of antihypertensive therapy. The goals of antihypertensive therapy decrease the complications and motalitv of cardiovascular system and prevent the promoting arteriosclerosis. In this study, we observed the blood pressure change of cb-hemorrhagic patients with hypertension who were hospitalized from 1996. 3. 1 to 1997. 2 .26 in Wonkwang Oriental Hospital. These patients had no antihypertensive therapy and were supplied herb med(Jaum sikpoongtang, Chungrijagamtang, Gojinumja) in medication. Our results suggested as follows. 1. Systolic and diastolic average BP at admission is $150.71{\pm}15.61mmHg$ and $95.00{\pm}8.8mmHg$ and this is hypertension state defining WHO 2. During one week in admission, the blood pressure demostrated a marked declination by SBP 8.97mmHg and DBP 6.22mmHg. 3. During two week in admission, the declination of SBP was significant in paired t-test(p<0.05) but, the declination of DBP was non-significant in paired t-test. 4. The blood pressure during third and fourth weeks gradually declined but, non-significant in test. According to the above results, we suggested that the BP declination Was affected by $Jamyang{\cdot}Jaum$ prescriptions in acute stage of cerebral hemorrhage.
