BACKGROUND: The macrophages activated by lipopolisaccharide produce numerous molecules and proteins, such as tumor necrotic factor-alpha (TNF-alpha), interleukin-6 (IL-6), IL-1beta, inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and free radicals, associated with inflammation. The response was occurred by intracellular cascaded, NF-kappaB pathway. So, the regulation of this pathway is very important in control of inflammation. OBJECTIVE: In this study, the anti-inflammatory and anti-oxidant effects of Sophora flavescens that is used empirically in oriental medicine and folk remedy were evaluated and the mechanism of the effects was studied. METHODS: By using the root extracts of Sophora flavescens, we performed experiment in LPS and interferon-gamma (IFN-gamma)-activated Raw 264.7 cells. We measured the production of NO, PGE2 and expression of iNOS and COX-2 in activated Raw 264.7 cells with Sophora flavescens root extract. Also, we tested anti-oxidant effect of Sophora flavescens root extracts by ELISA kit in activated Raw 264.7 cells, and the free radical scavenging effect of material itself by DPPH assay. RESULTS: The Sophora flavescens root extracts decreased the production of NO (p<0.001) and PGE2 (p<0.01) in Raw 264.7 cells activated by LPS and IFN-gamma. The expression of proteins, iNOS and COX-2, suppressed along with the elevated concentration of Sophora flavescens root extracts. The result of DPPH assay was that the test material itself had scavenging effect for free radical (p<0.001). And the antioxidant activity in activated Raw 264.7 cells was increased with the level of the Sophora flavescens root extracts (p<0.05). CONCLUSION: The Sophora flavescens root extracts suppressed the production of NO and PGE2 through the decreased expression of iNOS and COX-2. And the Sophora flavescens root extracts had the scavenging effect about free radicals itself and increased the antioxidant activity in activated macrophages.

BACKGROUND: It has been demonstrated that brief periods of calcium depletion and repletion (calcium-free preconditioning, CP) have cardioprotective effects as seen in ischemic preconditioning(IP) which enhances the recovery of post-ischemic contractile dysfunction and reduces the incidence of reperfusion-induced arrhythmia or infarct size after a prolonged ischemia. In the present study, we tested this paradoxical phenomenon in isolated rabbit hearts. MATERIAL AND METHOD: Hearts isolated from New Zealand white rabbits(1.5~2.0 Kg body weight) were perfused with Tyrode solution using the Langendorff technique. After stabilizing the baseline hemodynamics, the hearts were subjected to 45 minutes of global ischemia followed by 120 minutes of reperfusion with IP(IP group, n=7) or without IP (ischemic control group, n=7). IP was induced by a single episode of 5 minutes global ischemia and 10 minutes reperfusion. In the CP group(n=7), the hearts were subjected to perfusion with Tyrode solution with calcium depletion for 5 minutes and repletion for 10 minutes, and 45 minutes of ischemia and 120 minutes of reperfusion. Left ventricular function including developed pressure, dP/dt, heart rate, left ventricular end-diastolic pressure and coronary flow was measured. Infarct size was determined by staining with 1% triphenyltetrazolium chloride and planimetry. Data were analyzed by a one-way analysis of variance and Tukey's post-hoc test. RESULT: In comparison with the ischemic control group, IP significantly enhanced the recovery of the left ventricular function including the left ventricular developed pressure, contractility, and coronary flow; in contrast, these functional parameters of the CP group tended to be lower than those of the ischemic control group. However, the infarct size was significantly reduced by IP or CP(p<0.05). CONCLUSION: These results suggest that in isolated Langendorff-perfused rabbit heart model, CP(induced by single episode of 5 minutes calcium depletion and 10 minutes repletion) could not improve.

Mesenteric panniculitis is an extremely rare inflammatory condition of the adipose tissue of unknown etiology. It is characterized by extensive, progressive fibrosis of the mesenteric fat tissue, leading to tumor formation. Clinical manifestations vary according to the process involving the structures. Abdominal pain accompanied by nausea, malaise, pyrexia, and weight loss and a poorly defined mass are common presentations. Major pathologic changes include (1) degeneration of mesenteric fat, (2) an inflammatory reaction, and (3) fibrosis of the adipose tissue. We present four patients with an aggressive form of mesenteric pannicultis with characteristic histopathologic features. We discuss the relationship between the histopathologic features and the surgical intervention in these cases.

This study was done to investigate the effect volume overloading of right ventricle(RV) on the left ventricular(LV) volume and function in patients with isolated secundum type atrial septal defect(ASD) and to determine the hemodynamic indices affecting the postoperative reduction of RV size. Pre and postoperative echocardiogram and equilibrium radionuclide cardiac angiogram were analyzed in 39 patients of isolated secundum type ASD, who had their diagnosis confirmed by right heart catheterization and were operated at Seoul National University Hospital from January 1982 to July 1984. The ratio fo RV end-diastolic dimension to LV end-diastolic dimension(RVED/LVED), ratio of LV pre-ejection period and LV ejection time(PEP/LVET), ejection fraction(E.F.), fractional shortening(F.S.) mean velocity of circumferential fiber shortening(mVcf), peak ejection rate(PER) and peak filling rate(PFR) were measured in 24 normal control subjects and 39 patients with ASD before and after operation. The results obtained were as follows : 1) The postop. reduction of RV size could be correlated with age at operation, but showed no correlation with the degree of QP/Qs, main pulmonary arterial systolic, diastolic, mean pressure, RVEDP and previous RV size. 2) The ratio of postop. RVED/LVED(0.58+/-0.15) was significantly decreased, compared with the ratio of preop(0.96+/-0.28)(P<0.005)(Mean+/-1 S.D.). In preop and postop. status of ASD, the ratio of RVED/LVED was significantly larger than that of normal control subject(0.30+/-0.09)(P<0.005). 3) The ratio of preop PEP/LVET(0.33+/-0.02) was significantly decreased, compared with ratio of preop PEP/LVET(0.39+/-0.04)(P<0.005). There was significant difference between the ratio of preop. PEP/LVET and ratio of normal control subjects(0.33+/-0.05)(P<0.005), but no significant difference between the ratio of postop. PEP/LVET and ratio of normal control subjects(P>0.1). 4) There was no significant difference in LV systolic contractile functional indices between ASD group and normal control subjects and between pre and postop. status of ASD patients : LVEF was 63.5+/-6.1(%) in preop., 63.0+/-5.7(%) in postop and 62.4+/-6.6(%) in normal control subjects. F.S. was 27.3+/-5.7(%) in preop., 28.2+/-3.1(%) in postop. and 28.7+/-4.5(%) in normal control subjects. mVcf was 0.81+/-0.11(Cire/sec) in preop., 0.80+/-0.10(Circ/sec) in postop. and 0.82+/-0.14(Circ/sec) in normal control subjects. PER was 2.82+/-0.61(EDV/sec) in preop., 2.84+/-0.56(EDV/sec) in postop. and 2.84+/-0.45(EDV/sec) in normal control subjects. 5) The postop. PFR 3.34+/-0.46(EDV/sec) was significantly increased, compared with preop. PFR 2.51+/-0.46(EDV/sec)(P<0.005). There was significant difference between preop. PFR and normal control PFR 3.29+/-0.66(EDV/sec)(P<0.005), but no significant difference between postop. PFR and normal control PFR(P>0.1). 6) The postop. RVEF(51.4+/-6.3%) was significantly decreased, compared with preop. RVEF(54.5+/-9.9%)(P<0.005). Pre and postop. RVEF of ASD patient were significantly lower than RVEF of normal control group(60.3+/-3.1%)(P<0.01, P<0.005). The results indicate that postop. reduction of RV size could be correlated with age at operation. The effect of RV volume overloading on LV could not change systolic contractile functional indices, but diastolic filling index. There is many evidences suggesting that RV filling influences LV diastolic function which are occured by means of left ward shift of the interventricular septum and indirectly by linkage of filling of the two ventricules by common enclosure in the pericardium(underfilled LV volume and decreased LV compliance). Mildly diminished overall LV performance as shown by systolic time intervals appears to be related to the volume overload of the RV and to the concomitantly diminished volume of LV rather than to any myocardial contractility. LV systolic time inverval was non-invasive and sensitive index in assessing overall LV performance independent to LV geometric configuration and abnormal motion of regional ventricular wall.

BACKGROUND: It has been documented that brief repetitive periods of ischemia and reperfusion (ischemic preconditioning, IP) enhances the recovery of post-ischemic contractile function and reduces infarct size after a longer period of ischemia. Many mechanisms have been proposed to explain this process. Recent studies have suggested that transient increase in the intracellular calcium may have triggered the activation of protein kinase C(PKC); however, there are still many controversies. Accordingly, the author performed the present study to test the hypothesis that preconditioning with high concentration of calcium before sustained subsequent ischemia(calcium preconditioning) mimics IP by PKC activation. MATERIAL AND METHOD: The isolated hearts from the New Zealand White rabbits(1.5~2.0 kg body weight) METHOD: The isolated hearts from the New Zealand White rabbits(1.5~2.0 kg body weight) were perfused with Tyrode solution by Langendorff technique. After stabilization of baseline hemodynamics, the hearts were subjected to 45-minute global ischemia followed by a 120-minute reperfusion with IP(IP group, n=13) or without IP(ischemic control, n=10). IP was induced by single episode of 5-minute global ischemia and 10-minute reperfusion. In the Ca2+ preconditioned group, perfusate containing 10(n=10) or 20 mM(n=11) CaCl2 was perfused for 10 minutes after 5-minute ischemia followed by a 45-minute global ischemia and a 120-minute reperfusion. Baseline PKC was measured after 50-minute perfusion without any treatment(n=5). Left ventricular function including developed pressure(LVDP), dP/dt, heart rate, left ventricular end-diastolic pressure(LVEDP) and coronary flow(CF) was measured. Myo car ial cytosolic and membrane PKC activities were measured by 32P-gamma-ATP incorporation into PKC-specific pepetide. The infarct size was determined using the TTC (tetrazolium salt) staining and planimetry. Data were analyzed using one-way analysis of variance(ANOVA) variance(ANOVA) and Tukey's post-hoc test. RESULT: IP increased the functional recovery including LVDP, dP/dt and CF(p<0.05) and lowered the ascending range of LVEDP(p<0.05); it also reduced the infarct size from 38% to 20%(p<0.05). In both of the Ca2+ preconditioned group, functional recovery was not significantly different in comparison with the ischemic control, however, the infarct size was reduced to 19~23%(p<0.05). In comparison with the baseline(7.31 0.31 nmol/g tissue), the activities of the cytosolic PKC tended to decrease in both the IP and Ca2+ preconditioned groups, particularly in the 10 mM Ca2+ preconditioned group(4.19 0.39 nmol/g tissue, p<0.01); the activity of membrane PKC was significantly increased in both IP and 10 mM Ca2+ preconditioned group (p<0.05; 1.84 0.21, 4.00 0.14, and 4.02 0.70 nmol/g tissue in the baseline, IP, and 10 mM Ca2+ preconditioned group, respectively). However, the activity of both PKC fractions were not significantly different between the baseline and the ischemic control. CONCLUSION: These results indicate that in isolated Langendorff-perfused rabbit heart model, calcium preconditioning with high concentration of calcium does not improve post-ischemic functional recovery. However, it does have an effect of limiting(reducing) the infart size by ischemic preconditioning, and this cardioprotective effect, at least in part, may have resulted from the activation of PKC by calcium which acts as a messenger(or trigger) to activate membrane PKC.

Background:
The rapidly increasing socioeconomic strain caused by dementia represents a significant public health concern. Regional dementia centers (RDCs) have been established nationwide, and they aim to provide timely screening and diagnosis of dementia. This study investigated the clinical characteristics and progression of patients diagnosed with Alzheimer’s dementia (AD), who underwent treatment in RDCs or conventional communitybased hospital systems.
Methods:
This retrospective single-center cohort study included patients who were diagnosed with AD between January 2019 and March 2022. This study compared two groups of patients: the hospital group, consisting of patients who presented directly to the hospital, and the RDC group, those who were referred to the hospital from the RDCs in Pohang city. The clinical courses of the patients were monitored for a year after AD diagnosis.
Results:
A total of 1,209 participants were assigned to the hospital (n = 579) or RDC group (n = 630). The RDC group had a mean age of 80.1 years ± 6.6 years, which was significantly higher than that of the hospital group (P < 0.001). The RDC group had a higher proportion of females (38.3% vs. 31.9%; P = 0.022), higher risk for alcohol consumption (12.4% vs. 3.3%; P < 0.001), and greater number of patients who discontinued treatment 1 year after diagnosis (48.3% vs. 39.0%; P = 0.001). In the linear regression model, the RDC group was independently associated with the clinical dementia rating sum of boxes increment (β = 22.360, R 2 = 0.048, and P < 0.001).
Conclusion
Patients in the RDC group were older, had more advanced stages of conditions, and exhibited a more rapid rate of cognitive decline than patients diagnosed through the conventional hospital system. Our results suggested that RDC contributed to the screening of AD in a local region, and further nationwide study with the RDC database of various areas of Korea is needed.

BACKGROUND: In the studies of the distribution of time to death in trauma patients, the early deaths within several hours after injury were a large component of total trauma deaths. Due to the development of trauma system, overall mortality of trauma was decreased, but trauma is still the major cause of deaths. MATERIAL AND METHOD: From January 1994 to December 2003, trauma patients who had been admitted and had expired at tertiary hospital were enrolled. There was a total of 400 cases, a retrospective study was done to determine the distribution of trauma mortality according to the part of the body that were severely injured part and compared the difference between early deaths within 6 hours and late deaths after 6 hours. We also analysed the risk factors of early deaths due to trauma. RESULT: In severe injury to the head and abdomen, the distribution of mortality was bimodal. But, in severe chest injuries, the distribution was log-shape and most early deaths were almost of trauma related. The average of GCS were 5.86+/-4.15 for the early deaths and 8.24+/-5.02 for the late deaths (p <0.05). The AIS of thorax were 2.66+/-1.87 for the early deaths and 1.55+/-1.76 for late deaths. The risk factors for early mortality were non-EMS transportation (odds ratio 3.474), high AIS (odds ratio 1.491) and GCS (odds ratio 0.859). CONCLUSION: In trauma patients, the causes of early mortality were severe brain injury and massive hemorrhage. Also severe chest injuries were the major cause of the early deaths in truama. Early diagnosis of chest injury can frequently be missed in the acute trauma setting. Therefore, high index of suspicion, a careful examination, and aggressive surgical treatment are important in multiple trauma patients.
