  • Purpose : We aimed to investigate the clinical manifestations of and antibiotic resistance in culture-proven childhood salmonellosis. Methods : Clinical manifestations and laboratory data of and antibiotic use in subjects with culture-proven childhood salmonellosis, who were treated at the Chonbuk National University Hospital between September 1998 and August 2008, were analyzed retrospectively. Patients with underlying diseases or concomitant illnesses were excluded. Results : We assessed a total of 72 patients. There were 68 stool culture-positive cases, 7 blood culture-positive cases, and 3 both stool culture- and blood culture-positive cases. Salmonella group D was the most frequent pathogen in stool (63.9%) and blood (71.4%) cultures. Salmonella typhi was isolated in 1 case. Of the 72 patients, 45 (62.5%) were male children, of which 29 (40.3%) were aged <3 years. The patients most commonly presented with diarrhea (90.2%) and fever (83.3%). Leukocytosis (leukocyte count, >$15,000/{\mu}L$) and leukopenia (leukocyte count, <$4,000/{\mu}L$) were detected in 8.3% and 5.6% of the patients, respectively. Elevated serum C-reactive protein concentration (>5 mg/dL) and erythrocyte sedimentation rate (>20 mm/h) were observed in 88.9% and 58.3% of the patients, respectively. Fifty-two (85.2%) of 61 patients who had undergone antibiotic treatment received a third-generation cephalosporin as definitive antibiotic therapy. Multidrug resistance rate was 40.0 % in the first 5 years of the study and 71.4% in the last 5 years. No fatalities occurred in this series. Conclusion : Children with culture-proven salmonellosis showed relatively benign clinical outcomes. Appropriate antibiotic treatment of <2 weeks is probably adequate for those without a suppurative focus of infection. The incidence of antibiotic resistant isolates was recently seen to increase.

  • Background: N-acetylcysteine(ACE) is used both orally and intravenously in a variety of experimental pathologies resembling human disease states which exhibit endothelial toxicity as a result of oxidative stress, including acute pulmonary oxygen toxicity, septicemia and endotoxin shock. Despite these observations in vivo, it is not certain how this thiol drug produces its protective effects. ACE is a cysteine derivative which is able to direct1y react with oxygen radicals and may also act as a cysteine and glutathione(GSH) precursor following deacetylation. In this paper, we tried to know whether the therapeutic doses of ACE can modify the inflammatory function of the neutrophils and can increase the glutathione level of plasma in chronic obstructive pulmonary disease(COPD) patients. In addition, the effect of ACE to the purified neutrophil in terms of superoxide release and glutathione synthesis were observed. Method: Firstly, we gave 600mg of ACE for seven days and compare the release of superoxide, luminol-enhanced chemiluminescence from the neutrophils, neutrophil chemotaxis, and plasma GSH levels before and after ACE treatment in COPD patients. Secondly, we observed the dose dependent effect of ACE to the purified neutrophil's superoxide release and GSH levels in vitro. Results: 1) Usual oral therapeutic doses(600mg per day) of ACE for seven days did affect neither on the neutrophil's superoxide release, chemiluminescence, chemotaxis, nor on the plasma GSH concentration in the COPD patients. 2) ACE decreases the purified neutrophil's superoxide release and increase the GSH production in dose dependent fashion in vitro. Conclusion: Despite the fact that oral ACE treatment did not affect on the neutrophil's inflammatory function and plasma GSH concentration in COPD patients in usual therapeutic doses, it decreases the superoxide release and increases the GSH production from the isolated neutrophils in high molar concentrations. These findings suggest that to obtain an antioxidative effects of ACE, it might be needed to increase the daily dosage of ACE or therapeutic duration or change the route of adminisration in COPD patients.

  • The effect of feeding a cyclic oligosaccharide, $\beta$-cyclodextrin($\beta$CD) on plasma cholesterol and triacylglyceride concentrations and on antithrombotic activity were investigated in rats fed a control chow diet, or one either high in cholesterol or in saturated fat. The bleeding time of $\beta$CD-fed groups was significantly prolonged by 293%, 157% and 218% in normal, high cholesterol and high fat diet fed groups, respectively, as compared to the control group(p<0.05). The whole blood clotting time was significantly increased by 202%, 168% and 211% in normal, high cholesterol and high fat diet fed groups as compared to control group, respectively(p<0.05). The $\beta$CD diet caused a marked decrease in plasma total lipid(TL), triacylglyceride(TAG), total cholesterol (TC) and low density lipoprotein- cholesterol (LDL-C) concentrations. The plasma TL concentration was significantly decreased by 70%, 82% and 87% in normal, high cholesterol and high fat diet fed groups as compared to the control group, respectively(p<0.05). The plasma TAG concentration was significantly decreased by 89%, 43% and 59% in normal, high cholesterol and high fat diet fed groups, respectively, as compared to the control group(p<0.05). The plasma TC concentration was significantly decreased by 28%, 62% and 36% in normal, high cholesterol and high fat diet fed groups, respectively, as compared to the control group(p<0.05). The LDL-C concentration was significantly decreased by 39%, 54% and 25% in normal, high cholesterol and high fat diet fed groups as compared to control group, respectively(p<0.05). The plasma total bile acids contents of $\beta$CD group was significantly increased by 66%, 95% and 97% in normal, high cholesterol and high fat diet fed groups as compared to control group, respectively(p<0.05). The hepatic HMG-CoA reductase activity was significantly lowered by 41% in the $\beta$CD-fed group compared to normal diet fed rats(p<0.05). The fecal steroid excretions of the $\beta$CD groups was significantly increased by 167% in normal diet fed rats(p<0.05). These results suggest that the $\beta$CD has a biological active function on antithrombotic activity and is hypolipidemic, hypotriglyceridemic and hypocholesterolimic agents. These are all effects that can help to prevent obesity and coronary heart disease in humans.

  • Background : The poor prognostic factors of far-advanced pulmonary tuberculosis(FAPTB) are lymphocytopenia in the peripheral blood(PB)(< $1,000/mm^3$) and $T_4$-cell count ${\leq}500/mm^3$. However, the cause of PB lymphocytopenia in FAPTB is unclear. The aim of this study was to analyze the lymphocyte proportion and cytokines of the bone marrow(BM) in FAPTB patients with peripheral lymphocytopenia in order to clarify whether the limiting step of the lymphocytopenia occurs in production, differentiation, or circulation. Methods : This study included patients with FAPTB between August 1999 and August 2002 who visited Gachon Medical School Gil Medical Center. The exclusion criteria were old age(${\geq}65years$), cachexia or a low body weight, shock, hematologic diseases, or BM involvement of tuberculosis. The distributions of cells in PB and BM were analyzed and compared to the control group. The interleukin(IL)-2, IL-7, IL-10, TNF-${\alpha}$, Interferon-${\gamma}$, and TGF-${\beta}$ levels in the BM were measured by ELISA. Result : Thirteen patients(male : female=9:4) were included and the mean age was $42{\pm}12$years. The proportion and count of the lymphocytes in the PB were significantly lower in the FAPTB group ($7.4{\pm}3.0%$, $694{\pm}255/mm^3$ vs. $17.5{\pm}5.8%$, $1,377{\pm}436/mm^3$, each p=0.0001 and 0.002). The proportion of immature lymphocyte in the BM showed a decreasing trend in the FAPTB group($9{\pm}4%$ vs. $12{\pm}3%$, p=0.138). The IL-2($26.0{\pm}29.1$ vs. $112.2{\pm}42.4pg/mL$, p=0.001) and IL-10($3.4{\pm}4.7$ vs. $12.0{\pm}8.0pg/mL$, p=0.031) levels in the BM were significantly lower in the FAPTB group than those in control. The levels of the other cytokines in FAPTB group and control were similar. Conclusion : These results suggest that the cause of lymphocytopenia in PB is associated with a abnormality IL-2 and IL-10 production in the BM. More study will be needed to define the mechanism of a decreased reservoir in BM.

  • Carotid Intima-Media Thickness (CIMT) testing is a test that precisely assesses cerebrovascular and coronary heart diseases. According to many previous studies, CIMT predicts atherosclerosis and is highly correlated to cardiovascular disease risk factors. It has also been reported that CIMT is an independent predictor of risk factors for myocardial infarction and stroke. Therefore, the purpose of this study is to investigate CIMT and other independent factors through a correlation study with the clinical laboratory test results of a blood test. As a result, this study could not prove the correlation between CIMT and risk factors of cardiovascular disease (TC, TG, LDL cholesterol, and HDL cholesterol) due to an insufficient number of subjects. Nevertheless, a positive correlation was demonstrated between CIMT and ALT (p<0.05), GGT (p<0.05), Uric acid (p<0.05), and CEA (p<0.05) at a statistically significant level, suggesting a continuation of the study.

  • Podocytopathy is glomerular lesions characterized by podocyte injury. It is observed in various glomerular diseases, but minimal change disease and focal segmental glomerulosclerosis (FSGS) are the prototypes. In this review, morphologic features of podocyte injury and subtypes of FSGS will be reviewed briefly. Effacement of podocyte foot processes is the most common feature of podocyte injury. As podocytic injury progresses, intracytoplasmic vacuoles, subpodocytic cyst, detachment of podocytes from the glomerular basement membrane and apoptosis develop. Glomerular capillary loops in epithelium-denuded area undergo capillary collapse. Synechia and hyalinosis may accompany this lesion. To manifest segmental sclerosis, podocyte loss above a threshold level may be required. Injured podocytes can injure neighboring intact podocytes, and thereby spread injury within the same lobule. FSGS can be categorized into five subtypes by morphologic characteristics; not otherwise specified (NOS), perihilar, cellular, tip, and collapsing types. Each subtype has been reported to show different clinical courses and associated conditions, but there are controversies on its significance. With recent progress in the discovery of genetic abnormalities causing FSGS and plasma permeability factors, we expect to unravel pathophysiology of FSGS and to understand histological sequences leading to FSGS in near future.

  • An 11-year-old intact male Yorkshire terrier had intermittent vomiting, anorexia and depression for a month. Clinical laboratory works showed azotemia and anemia. Chronic kidney disease with developing anemia was diagnosed clinically. Clinical signs were resolved but anemia was deteriorated and blood transfusion was performed. On 10 hours after transfusion, the dog showed acute respiratory distress. Transfusion related acute respiratory distress syndrome (ARDS) was diagnosed based on acute clinical signs, risk factors of transfusion, bilateral alveolar infiltration on thoracic radiographs, and $PO_2:FiO_2$ ratio less than 200 on arterial blood analysis. The dog died within 2 hours after ARDS diagnosis.

  • Pulmonary thromboembolism occurs in old patients with risk factors, such as, immobilization, chronic medical disease, trauma, a hereditary hypercoagulable state, and others. However, we experienced a young man with a massive pulmonary thromboembolism attributed to immobilization due to computer gaming. The patient had been playing computer games in a seated position for at least five hour continually, and for twelve hours per day over a two-week period. The 36-year-old patient was transferred to our institute rule out the possibility of an acute myocardial infarction. Computer tomography revealed intraluminal filling defects in the distal main pulmonary artery and the left popliteal vein. He received thrombolytic therapy and subsequently recovered without complications. This case raises the possibility that prolonged computer gaming is a risk factor of thromboembolism in young adults.
