Just as hyperbetalipoproteinemia is the most common kind of familiar hyperlipoproteinemia, hyperprebetalipoproteinemia or increased very low density lipoprotein (VLDL) and its associated hypertriglyceridemia is an abnormality frequently found in association with several metabolic and nutritional disorders. This VLDL abnormality is demonstrable in high percentage of insulin dependent diabetic children before they receive treatment. It is also observed in many older, overweight, insulin resistant diabetic, with poor control of diabetes. An elevation of VLDL was also observed after ethanol intake. A mild to moderate degree of VLDL elevation is the most frequently observed from of clinical hyperlipidemia. Many investigators reported that hyperprebetalipoproteinemia (hypertriglyceridemia) is associated with an increasing incidence of coronary artery disease. As opposed to hyperbetalipoproteinemia, hyperprebetalipoproteinemia is prone to influence on the development of atherosclerosis in the middle and older aged persons which indicates the importance of triglyceride determination in these aged groups. There has been relatively rare study reported on the triglyceride metabolism in patients with congestive heart failure, essential hypertension and liver disease in Korea. This study was designed to determine serum triglyceride, free fatty acid and glycerol in the disease mentioned in Busan University Hospital between jan. 1975 and December 1976 and analized the change of lipid profile in each different condition. The results were as follows; 1. The mean of serum FFA, triglyceride and glycerol in the 37 normal were as follows 502.32+/-146.54microEq/L, 111.84+/-40.53mg% and 432.00+/-212.13microM/ml. 2. 23 patients with congestive heart failure showed a significant reduction in serum triglycerides (91.96+/-27.80mg%) and a significant increase in serum free fatty acid (576.77+/-129.67microEqL) and glycerol (432.50+/-212.13microM/ml). 3. In 15 patients with essential hypertension a significant elevation of serum triglycerides (149.38+/-42.28mg%) was noted. 4. In 13 patients with liver cirrhosis, a reduction in serum triglycerides (80.50+/-34.27mg%) was noted.

Three freshwater snail species of the family Lymnaeidae have been reported from Korea, Radix auricularia coreana, Austropeplea ollula and Fossaria truncatula. Out of 3 lymnaeid snail species, A. ollula was naturally infected with the Echinostoma cinetorchis cercariae (infection rate = 0.7%). In the experiments with the laboratory-bred snails, F. truncatula as well as A. ollula was also susceptible to the E. cinetorchis miracidia with infection rates of 25% and 40%, respectively. All of three lymnaeid snail species exposed to the E. cinetorchis cercariae were infected with the E. cinetorchis metacercariae. It is evident that A. ollula acts as the first molluscan intermediate host of E. cinetorchis in Korea, and F. truncatula may be a possible candidate for the first intermediate host of this intestinal fluke. Also, three lymnaeid snail species targeted were experimentally infected with E. cinetorchis metacercariae.

BACKGROUND: It has been a standard practice in many institutions to combine light general anesthesia with epidural block for abdominal and pelvic surgery. We attempted to prove the effectiveness of prehydration and to find an suitable epidural local anesthetic dose in terms of hemodynamic stability for upper abdominal surgery. METHODS: For preliminary studies, 11 patients scheduled for elective upper abdominal surgery had received general anesthesia immediately after epidural anesthesia. After epidural injection of 10~16 mL of 2% plain lidocaine into the T9~10 intervertebral space, the changes in blood pressure were observed. Thirty-two patients scheduled for elective upper abdominal surgery were divided into two groups. In group A (study group), after prehydration with Hartmann solution (10 mL/kg), 5~7 mL of 2% plain lidocaine was injected into T8~9 or T9~10 intervertebral space and general anesthesia was then induced. Group B (control group) received general anesthesia only. RESULTS: There were no significant differences in hemodynamics between the epidural with general anesthesia and the control group except SVR (systemic vascular resistance). SVR in group A increased in contrast to the group B in which it remained unchanged. CONCLUSIONS: The combined epidural and general anesthesia, using prehydration and 0.5~1 mL/segment of 2% plain lidocaine at the T8~9 or T9~10 intervertebral space was safe without significant hemodynamic changes.

The gag encoded p24 protein of human immunodeficiency virus-1 (HIV-1) is a major constitutent of the viral core, and is also known as one of the most immunodominant antigens in the host immune response against the HIV-1. Based on the neutralizing ability of anti-p24 antibodies as well as their rapid appearance in human serum after viral infection, the development of vaccines and diagnostic tools targeting the p24 protein and anti-p24 antibodies is of great interest. For the characterization of the immunological properties of the HIV-1 p24 protein, in a previous study, putative B-cell epitopes were identified by screening the reactivity of a goat anti-p24 antiserum to a large array of overlapping synthetic peptides covering the whole p24 sequence. Four peptides were identified for their abilities to elicit a strong B-cell response, which sequences comprises the regions p24 (164-182), (202-221), (217-236) and (232-256), respectively. In the present study, the immunogenicity and differential properties of each of these individual epitopes were further characterized. To evaluate the time course of the antibody response, BALB/c mice were immunized with the HIV-1 p24 protein and their serum titers against each of these peptides were determined. The earliest immune response was observed against the p24 (202-221) peptide, which also showed the highest antibody titer against the immunized antigen. Furthermore,. enzyme-linked immunosorbent assay with HIV-1 p24 protein coated microtiter plates revealed that anti-p24 (202-221) antiserum has the most pronounced reactivity against the native p24 protein. Since the p24 (202-221) epitope has also been reported to include a cytotoxic T-lymphocyte epitope, it is suggested that this region might represent a powerful antigenic site responsible for eliciting both T- and B-cell immune response. The possible application of this specific epitope in vaccine development or AIDS diagnosis is discussed.

Both idiopathic pulmonary fibrosis (IPF) and pulmonary involvement of collagen vascular disease(CVD) are well known cause of diffuse interstitial lung disease which lead to fibrosis and honeycombing. We analyzed HRCT findings of 33 patients with IPF and 14 patients with CVD in terms of predominant pattern, site of involvement, mediastinal lymph node enlargement, pleural change and pulmonary volume loss. Criteria of mediastinal lymph node enlargement and pleural thickening were 15mm in long diameter and 3mm, respectively. Volume loss of the lung was measured by using hilar height ratio (apex to hilum/hilum to diaphragmatic dome). Mean age was 61 years for IPF and 46 years for CVD and male: female ratio was 27:6, 4:10, respectively. Predominant HRCT pattern was honeycombing for IPF (63%), and ground-glass opacity for CVD (66%) (p=0.001). Predominantly, subpleural involvement was seen in 90% for IPF and 74% for CVD. Mediastinal lymph node enlargement was seen in 47% of the patient with IPF and 14% with CVD (p=0.004). pleural thickening was seen in 97% of the patients with IPF and 42% with CVD (P=0.002), Pleural effusion was seen in 10% of the patients with IPF and 36% with CVD (P=0.009). Hilar height ratio of more than 1.5 was seen in 84% of the patients with IPF and 29% with CVD. In conclusion, our study shows that patients with IPF are prone to have more progressed stage of pulmonary fibrosis than the patients with CVD on HRCT.

Two factors of the ventricular function, systolic contractile and diastolic relaxing functions, cooporate in pumping the adequate blood volumes to suffice bodily demands. In some hypertensive patients with marked left ventricular hypertrophy, the intact systolic function of the ventricle associated with clinical symptom of congestive heart failure(CHF), which is considered to be a consequence of diastolic dysfunction. In this study 10 hypertensive patients(group A) complaining of exertional dyspnea or chest pain with increased left ventricular mass index and normal systolic function and 6 normotensive controls(group B) were examined by cardiac catheterization and echocardiography to assess the left ventricular systolic and diastolic function and ventricular responses to constant infusion of nitroprusside. Various systolic and diastolic function indices were measured by cardiac catheterization and echocardiography. 1) The ejection fraction(EF), fractional fiber shortening, mean velocity of circumferential fiber shortening, left ventricular(LV) peak+dp/dt, change of slope of LV peak systolic pressure-volume and pressure-dimension relations in group A were not different from those of group B in the resting states. 2) Diastolic dysfunction was evidenced by prolonged A2D time, decreased OR slope, decreased peak negative dp/dt and increased diastolic time constant 'T' in group A. 3) Cardiac index by thermodilution method was negatively related to left ventricular mass index(LVMI) measured by echocardiography, whereas time constant T was positively related to LVMI. 4) With constant infusion of nitroprusside, LV systolic pressure, LV end-diastolic pressure and pulmonary arterial pressure were decreased, and left ventricular end-systolic stress and stroke work index(SWI) derived from left ventricular pressure-volume loop area were decreased, EF was increased, but time constant T was prolonged and cardiac output(CO) by thermodilution method was decreased in group A. 5) In group B, with constant infusion of nitroprusside, EF, SWI and CO were pratically unaffected and time constant T was not prolonged significantly. These reults suggest that patients with hypertensive hypertrophic left ventricle is associated with diastolic dysfunction, which could further be exacerbated by a vasodilator such as nitroprusside.

Cardiac output depends on the ability of systolic ejection and diastolic filling of the heart. M-mode echocardiography can provide accurate clinical assessment of left ventricular systolic and diastolic functions. To see whether there are changes of the left ventricular function in asymptomatic hypertensives and if any kind of dysfunction and whether any relationship between the pattern of the ventricular hypertrophy and type of ventricular dysfunction exists, the authors examined the systolic and diastolic function indices of the left ventricle in 50 normotensives and 88 hypertensives composed of 18 patients without left ventricular hypertrophy(group 1), 40 patients with disproportionate septal thickening (group 2) and 30 patients with concentric left ventricular hypertrophy(group 3). Obtained results were as follows : 1) Blood pressure & left ventricular mass index were increased significantly in each hypertensive group compared to normal control. 2) Ejection fraction & fractional shortening in the hypertensive groups were not different from the normotensive control group. 3) Left ventricular isovolumic relaxation time(A2D time) was prolonged in each hypertensive group, especially in group 3. 4) Left atrial emptying index (AEI) was decreased in each hypertensive group. 5) Left ventricular percent ventricular A wave (% VAW) was increased in all hypertensive groups. Above study suggested that the left ventricular diastolic function could be impaired in the hypertensives without associated systolic dysfunction, and the degree of the diastolic dysfunction was not much affected by the type of left ventricular hypertrophy, but the more prolonged A2D time in the concentric hypertrophy group.

Acromioclavicular joint injuries are recently increased, but there are still controversies as to the proper choice of treatment. We treated thirty cases of acromioclavicular injuries, among these, twenty five cases were done by operative method and five cases conservatively from August 1979 to June 1988. The results were as follows, 1. The injuries were composed of one case of Type 1, 7 cases of Type 2 and 22 cases of Type 3. 2. The result of conservative treatment consisted of 2 cases of good, 1 case of fair and 2 cases of poor. 3. The final outcome of operative method was better than that of conservative one, which consisted of 16 cases of good and 9 cases of fair. 4. The cause of fair results in operative method was thought to residual lexity of the repaired coracoclavicular ligament. 5. The key point of operative treatment in acromioclavicular separation was firm and strong reconstruction of the coracoclavicular ligament. 6. Modified method of coracoclavicular ligament reconstruction using coracoacromial ligament with bone block has been tried.

OBJECTIVES: Culture of sputum is apt to be contaminated through oral cavity and proximal airway. Therefore, identification of true etiologic agents by sputum culture is not always reliable. In order to differentiate the pulmonary infection from non-infectious disease and to identify the true etiologic agent of acute pulmonary infection, we used PSB(Protected Specimen Brushing) and evaluated the efficacy of PSB. METHODS: In 168 patients with acute febrile illness with pulmonary infiltrations(male 106, female: 61, mean age: 49.5+/-17.6), we performed PSB via a bronchoscope and compared the results along with blood culture and sputum culture. Protected specimen brush was introduced through biopsy channel of bronchoscope and was rotated within the purulent secretions. Tip of the brush was severed with aseptic technique and was immersed in 1cc of Ringer's lactate solution and vigorously mixed for 1 minute. The specimen was submitted for quantitative culture within 15 minutes and was regarded positive culture if colony forming units were above 10(3)/ml. RESULTS: Using PSB for the diagnosis of pulmonary infection, sensitivity was 71.1% and specificity was 84.296. PSB was helpful in identifing true etiologic agent among several potentially pathogenic organisms. Using PSB for the diagnosis of UAP (ventilator associated pneumonia), sensitivity was 72.4% and specificity was 100%. CONCLUSION: Use of PSB can be a helpful method for the diagnosis of pulmonary infection and identification of its etiologic agents.
