Gastric cancer is the most common gastrointestinal malignancy in Korea. Identification and evaluation ofgastric mass lesions and regional-distant metastases by abdominal CT scan are important for the treatment planningand prognostic implications of gastric cancer patients. Author reviewed CT scan are important for the treatemntplaning and prognostic implications of gastric cancer patients. Author reviewed CT scan of 61 cases of pathologyproven gastric cancer, retrospectively, for recent 20 months from July 1983 to Feb. 1985 at department ofradiology, Korea University, Hae Wha Hospital. The results were as follows: 1. There were 50 cases of advanced adenocarcinoma, 8 cases of early gastric cancer, 2 cases of leiomyosarcoma, and 1 case of lymphoma in total 61cases. 2. The sex ratio of male to female was 2:1. Age distribution was from 24 to 75 year old and peak incidencewas in 6th decade. 3. The most frequent site of involvement with gastric cancer was gastric antrum in 51%. 4. 48of the 50 patients with advanced gastric adenocarcinoma(96%) had a wall thickness greater than 1 cm, and all of 8cases of early gastric cancer had a wall thickness less than 1 cm. Regional lymph node tumor infiltration wasfound in 100% of gastric wall thickness greater than 2.0cm, in 64% of cases of 1.5 to 2.0cm, in 50% of cases of1.9 to 1.5cm, and 12.5% of cases of less than 1.0cm. 5. In a comparison of enlargement of reginal lymph node by CTscan to tumor infiltration of regional lymph node by histology, senitivity was 52%, specificity was 87%, and reliability was 66%. 6. The structures involved by distant metastases of these cases were the retroperitoneallymph node in 15, liver in 8, and pancrease in 3. 7. The diagnostic accuracy of CT staging was considered about68% by correlation of the surgical and histological findings. 8. The CT scan is one of the accurate and simpletool for evaluation of size, shape, extent, as well as distant metastases in the cases of gastric malignancies.

The adult trematodes, Fasciola hepatica, Eurytrema pancreaticum and Paramphistomum cervi, employed in this experiment were obtained from the cattle slaughtered at the local abbatoir. The worms selected and washed several times in normal sterilized saline solution. Each about ten of intact F. hepatica, fourty of E. pancreaticum, and twenty of P. cervi were incubated in 50 cc volume of special incubation flasks with incubation medium consisting of 10 cc. of Krebs-Ringer phosphate buffer(pH 7.4) The incubation medium was added C(14)-1-acetate and non-radioactive carrier Na-acetate so as to contain acetate concentration of 50 mg per cent . The worms were allowed to incubate for 5 hours in the Dubnoff metabolic shaking incubator at 38 C. After incubation period, respiratory CO(2) samples from central well of incubation flask were analysed for total CO(2) production rate and their specific activity of respiratory CO(2). The lactate and pyruvate appearance rates were determined by analyzing the lactate and pyruvate concentration in a medium after incubation. The glycogen samples isolated from worms were analyzed for the tissue concentration and their radioactivities in order to determine the turnover rate of glycogen pool. Radioactivities of these series of experiments were counted by an endwindow Geiger-Muller counter as an infinitely thin samples. The quantitative analysis of C(14)-acetate utilized by F. hepatica, E. pancreaticum and P. cervi were compared and discussed in this report. According to these data of the experiment, it is suggested that the fatty acid such as acetate may play a part of their oxidative process into the respiratory CO2 and the synthetic process into glycogen in the above species of trematodes.

Journal of Cardiovascular Ultrasound 2014;22(3):101-110
Contrast echocardiography is broadly described as a variety of techniques whereby the blood pool on cardiac ultrasound is enhanced with encapsulated gas-filled microbubbles or other acoustically active nano- or microparticles. The development of this technology has occurred primarily in response to the need improve current diagnostic applications of echocardiography such as the need to better define left ventricular cavity volumes, regional wall motion, or the presence or absence of masses and thrombi. A secondary reason for the development of contrast echocardiography has been to expand the capabilities of echocardiography. These new applications include myocardial perfusion imaging for detection of ischemia and viability, perfusion imaging of masses/tumors, and molecular imaging. The ability to fill all of these current and future clinical roles has been predicated on the ability to produce robust contrast signal which, in turn, has relied on technical innovation with regards to the microbubble contrast agents and the ultrasound imaging paradigms. In this review, we will discuss the basics of contrast echocardiography including the composition of microbubble contrast agents, the unique imaging methods used to optimize contrast signal-to-noise ratio, and the clinical applications of contrast echocardiography that have made a clinical impact.

BACKGROUND: In recent years, the incidence of obesity increased in Koreans. The main cause suggested is the diet style of Korean changed to that of Western. It has been proved that obesity is a risk factor or an aggravating factor of hypertension and diabetes mellitus, cardiovascular disease, etc. Primary physician has been interested in the correlation of blood pressure with relative body weight and aging. The purpose of this study was to focus on the influence of age and relative body weight on blood pressure. METHODS: Subjects were collected from 2,068 adults who had received Adult Health Examination. That subjects were divided according to age, relative body weight and then the relation of blood pressure with age according to relative body weight and relation with relative body weight according to age were investigated. RESULTS: Systolic blood pressure increased significantly according to age in all male and female three weight groups and then increased significantly according to relative body weight in all male and female three age groups except male seventh decade group. Diastolic blood pressure increased significantly according to age in all male and female three weight groups except male obesity group and then increased significantly according to the relative body weight in all male and female three age groups except male and female seventh decade groups. Systolic blood pressure has higher correlation with age than relative body weight and diastolic blood pressure has higher correlation with relative body weight in male. In female, systolic and diastolic blood pressure have higher correlations with age. CONCLUSIONS: It can be suggested that blood pressure increase significantly according to aging process and relative body weight. These two factors have a little different effects to systolic and diastolic blood pressure according to sex. Relative body weight has more effect to diastolic blood pressure than systolic blood pressure in male.

Recently, CT scan, CT sialogram, radionuclide imaging and ultasonogram are widely applicated in conjuctionwith conventional studies such as plain film, sialogram and arteriogram for the diagnosis of salivary glanddisease. Among them, ultrasonogram porvides safe, noninvasive, and reliable way to diagnose salivary glanddisease. Authors evaluated ultrasonographic and sialographic findings of patients with suspected salivary glanddisease in 16 cases at Korea University Hosital for 8 months. (from Dec. 1983 to Aug. 1984). The following resultsare observed. 1. Final diagnosis of 16 cases were 2 cases of stone, 1 case of pleomorphic adenoma, 2 cases ofneurilemmoma, 3 cases of chronic sialademitis, 1 case of abscess, 2 cases of Retention cyst, 1 case of psendocyst,1 case of tuberculous lymphadenopathy, and 3 cases of normal finding. 2. Diagnostic ultrasonogram providesaccurate information for the size, location and character of the lesion, and differentiates intragladular lesionsfrom extraglandular ones. 3. Ultrasonogram is one of convenient, reliable and initial modality for the diagnosisof salivary gland disease.

The purpose of this study was to investigate the frequency of the meniscal flounce on MR imaging in patients who underwent arthroscopy or open surgery due to symptoms related to internal derangement of the knee, and to investigate associated findings in patients with meniscal flounce by comparing and analyzing the findings from MR imaging and surgery. MR images obtained from 116 knees before surgery were reviewed retrospectively. Seven medial menisci showed buckled, wavy flounce on sagittal MR images. None of the lateral menisci showed flounce. We reviewed the surgical records of all seven patients and the videotapes of six of the patients undergoing arthroscopy or open surgery. The frequency of flounce on sagittal MR images was 6.0% in the medial meniscus and was completely absent in the lateral meniscus. On coronal MR images, the truncated appearance of the affected meniscus was demonstrated in five patients, and a valgus deformity was seen in three patients. Five patients showed a moderate to large amount of joint effusion. On MR imaging and in surgery, ligament injuries were found in six patients (six medial collateral ligament injuries, five anterior cruciate ligament injuries, and two posterior cruciate ligament injuries). Non-specific synovitis was found in the one remaining patient. In the surgery of all seven patients, no tears were found at the meniscus itself showing flounce. In conclusion, the meniscal flounce seen on sagittal MR imaging can be a rare appearance of a transient distortion of a normal meniscus due to a valgus deformity caused by a MCL tear and/or due to an external rotation induced by cruciate ligament injury or positioning of knee joint within the magnet. The meniscal flounce should be interpreted carefully because it frequently appears truncated on the coronal scan and can simulate a meniscal tear.

A clinical and laboratory study was conducted on 58 children who had been admitted to out pediatric department from February to September 1979, under the clinical diagnosis of septicemia. Following results were obtained: 1. Boys were affected more frequently than girls(1.3:1), and highest incidence was noticed in newborn period, comprising 50% of the total cases. 2. The common clinical manifestations, in order of frequency, were fever, lethargy, jandice, poor sucking and abdominal distension, and hyperbilirubionemia was the most common assocaited disease, followed by anemia and leukemia. 3. Clinical course revealed death in 6 patients(10.3%), discharge against advice in 7cases(21.1%) and complete recovery in the remaining 45 cases(77.6%). 4. Peripheral blood count showed leukocytosie in 40%, leukopenia in 12.1% and thrombocytopenia was seen in 45% of cases. 5. Gram staining of buffy coat smear showed bacteria in 34.5% and especially high ratio was noticed in newborn infants(48.3%). 6. Positive blood culture was seen in 39.7% with highest ratio of 45% in newborn infants. In positive blood culture group, toxic granules were noted in 32.8%, shift to left in 25.9%, hrombocytopenia in 18.9% and positive buffy coat smear in 15.5%. In summary, thrombocytopenia, toxic granules, shift to left were quite helpful in early diagnosis of sepsis. In addition to diagnostic value, examination of buffy coat smear could aid physician to select appropriate antibiotic regimen especially in sepsis of newborn period.

PURPOSE: The human fetus is primarily dependent on the placenta for its nutrition. However, as the fetus matures, it swallows increasing amounts of amniotic fluid, which contributes to the growth of fetus. Accordingly fetuses with congenital obstruction of the gut at high level have a reduced capacity for intestinal absorption of amniotic fluid. We undertook a study to investigate the effect of congenital gut obstruction on fetal growth. METHOD: A retrospective review of the records of all patients presenting congenital gut obstruction over 6-year period (from 1992 to 1997) in Chung-ang Gil hospital was performed. Patients with a complete proximal obstruction were included in group A; patients with incomplete or lower obstruction were included in group B. RESULT: 1) The ratio of male to female was 1.5:1. The mean birth weight and gestational age were 2.89+/-0.60kg and 38.7+/-0.20weeks. The mean birth weight and gestational age in group A were 2.68+/-0.69kg and 37.8+/-0.25weeks. The mean birth weight and gesnal age in group B were 2.980.54kg and 39.1+0.17weeks. There was significant difference between group A and B (P<0.01). 2) Significant differences were found between group A and B in prematurity and growth retardation rate (P<0.01). No significant difference was found between group A and B in associated anomaly rate (P>0.05). 3) In group A, 3 (42.8%) of 7 patients with associated anomalies had IUGR, whereas 8 (40.0%) of 20 patients without associated anomalies had IUGR (P>0.05). The corresponding figures for group B were 23.0% and 14.8%, respectively (P>0.05). CONCLUSION: Congenital gut obstruction causes IUGR by reducing intestinal absorption of amniotic fluid and the effect of IUGR is more pronounced as the obstruction is proximal to jejunum rather than distal to it.

A case of syndrome of inappropriate secretion of antidiuretic hormome (SIADH) associated with herpes zoster ophthalmicus is reported. A 77-year-old man was admitted for treatment of left facial pain and vesicular lesions during 7 days. On admission, physical examination revealed vesicular eruptions on the left face and on neurologic examination, he revealed an alert, well-oriented mentality. Neither sensory disturbance nor nuchal rigidity was noted. Further investigation revealed hyponatremia 115mEq/L, low serum osmolality, high urine osmolarity, high urinary sodium secretion, normal renal function, normal adrenal and thyroid function. Cerebrospinal examination revealed a pleocytosis, mild protein elevation, normal glucose. No malignant cells were present and microorganism examinations were negative. Only water restriciton was started. But he revealed confusional mentality and aggravation of hyponatremia(110m2q/L). Intravenous hypertonic saline also was started, and the patient's sensorium was improved in accordance with the increase in serum sodium concentration. In the absence of other recognized causes we suggest that the two conditions(SIADH and Herpes Zoster Infection) may have related and speculate on possible mechanisms. In this report, we postulate that the hyponatremia was due to SIADH and that SIADH was caused by the infection of varicella-zoster virus(VZV) in central nervous system.
