  • The effects of Sparassis crispa extracts fermented with isolated strain from S. crispa on antioxidant and immunological activities were determined. S. crispa extracts fermented with Meyerozyma guilliermondii FM showed significantly higher total phenol contents and DPPH radical scavenging activities compared to those fermented with lactic acid bacteria. In methotrexate-induced immunosuppressed rats, reduced levels of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-2, and immunoglobulin E (IgE) and increased levels of IL-10 were detected in S. crispa extract injected groups regardless of fermentation. We confirmed that rats treated with S. crispa fermented with M. guilliermondii FM showed higher blood leukocyte contents compared to other treatments. These results suggest that M. guilliermondii FM has high potential as a starter culture for fermentation of S. crispa extracts with increased antioxidant and immunological activities.

  • Purpose: Continuous irrigation method is an important step in managing wound infection. V.A.C. devices have been used in intractable wounds for reducing discharge, improving local blood flow, and promoting healthy granulation tissue. We expect synergistic effects of reduced infection and more satisfactory, accelerated wound healing when using both methods simultaneously. This study evaluated continuous irrigation combined with V.A.C. appliance for treatment of infected chronic wounds. Methods: We reviewed data from 17 patients with infected intractable chronic wounds. V.A.C. device (Group A) was used in 9 patients, and V.A.C. with antibiotics irrigation (Group B) was used in 8 patients. We placed Mepitel$^{(R)}$ on the surface of wound and placed an irrigation and aspiration tube on each side. A sponge was placed on the Mepitel$^{(R)}$ and covered with film dressing. The wound was irrigated continuously with mixed antibiotics solution at the speed of 200 cc/hr and aspirated through the wall suction at the pressure of -125 mmHg. V.A.C. applied time, wound culture and wound size were compared between the two groups. Results: No complication were seen in two groups. Compared with Group A, in the Group B, V.A.C. applied time was shortened from 32.7 days to 25.6 days and showed efficacy in the reduction rate of wound size. No statistical differences were shown in bacterial reversion. Conclusion: V.A.C. appliance with continuous irrigation is an effective new method of managing infected chronic wounds and useful to reduce treatment duration and decrease wound size. Moreover it could be applied more widely to infected wound.

  • Purpose: To investigate the differences in clinical features and laboratory findings between group D and non-group D non-typhoidal Salmonella (NTS) gastroenteritis in children. Methods: A retrospective chart review of children diagnosed with NTS confirmed by culture study was performed. The clinical features and laboratory findings of group D and non-group D NTS were compared. Results: From 2003 to 2012, 75 cases were diagnosed as NTS at our center. The number of group D and non-group D patients was 45 and 30, respectively. The mean age was higher in group D than in non-group D patients (5.1 years vs. 3.4 years, p=0.038). Headaches were more frequently observed (p=0.046) and hematochezia was less frequently observed (p=0.017) in group D than in non-group D NTS gastroenteritis patients. A positive Widal test result was observed in 53.3% of group D and 6.7% of non-group D NTS cases (O-titer, p=0.030; H-titer, p=0.039). There were no differences in white blood cell counts, level of C-reactive protein and rate of antimicrobial resistance between group D and non-group D cases. Conclusion: The more severe clinical features such as headache, fever, and higher Widal titers were found to be indicative of group D NTS gastroenteritis. Additionally, group D NTS gastroenteritis was more commonly found in older patients. Therefore, old age, fever, headache, and a positive Widal test are more indicative of group D NTS than non-group D NTS gastroenteritis. Pathophysiological mechanisms may differ across serologic groups.

  • A case is reported of a man with malignant fibrous histiocytoma (MFH) in right thigh who developed streptococcal toxic shock syndrome (STSS) during postoperative radiotherapy. Before radiotherapy, a patient complained wax and wane lymphedema following wide excision of tumor mass which was confirmed as MFH. He took some nonsteroidal antiinflammatory drug (NSAID) for about one month. He suffered preexisting hepatitis C virus (HCV) infection, diabetes and well-controlled hypertension. The patient received conventional radiotherapy to right thigh with a total dose of 32.4 Gy at 1.8 Gy per day. At last radiotherapy fraction, cutaneous erythematous inflammation was suddenly developed at his affected thigh. At that time, he also complained of oliguria, fever and chills. The patient was consulted to internal medicine for adequate evaluation and management. The patient was diagnosed as suggested septic shock and admitted without delay. At admission, he showed hypotension, oliguria, constipation, abnormal renal and liver function. As a result of blood culture, Streptococcus pyogenes was detected. The patient was diagnosed to STSS. He was treated with adequate intravenous antibiotics and fluid support. STSS is one of oncologic emergencies and requires immediate medical intervention to prevent loss of life. In this patient, underlying HCV infection, postoperative lymphedema, prolonged NSAID medication, and radiotherapy may have been multiple precipitating factors of STSS.

  • The effect of different fatty acids supplementation on antobody production of Salmonella typhi was studied in ICR mice. Subjects supplemented their diets with $50\mu$g of extracted pig oil(as a saturated fatty acid) and fish oil (as a unsaturated fatty acid) / 2 days for 8 weeks. Blood was collected control and experimental groups of mice after 8 weeks of oil supplementation. The different fatty acids supplementation reduced unsaturated fatty acids composition in mice liver such as $C_{18:3}, \; C_{20:3}\; and\; C_{20:4}\; except\; C_{18:1}\; and\; C_{18:2}/C_{18:0}$ in fish oil and pig oil groups compared to control group. Also, the phagocytic activities of mice macrophages for Candida albicans was reduced by 6% in pig oil group and 9% in fish oil group than control group. The antigen-stmulated lympocite proliferative response was significantly increased by fatty acid in pig oil group(48%) but 57% in fish oil group. The different fatty acid supplementation increased antibody production in both experimental groups than control group ; this increase was only significant in pig oil group(1:$2^4$) on mice but not in fish oil group(1:$2^0$) compared to control group(1:$2^0$), however, increased antibody titer in both groups in vitro spleen cell culture supernatant(1:$2^3$ in fish oil group and 1:$2^2$ in pig oil group compared to control group 1:$2^0$). Thus, fish oil supplementation was immunosuppresive agent in macrophage phagocytosis, in-vivo antobody producibilities and lympocyte proliferation but pig oil supplementation was more effective than fish oil in antibody formation in-vivo. We find that antibody producibilities affected by fed on different fatty acids were considered by balance between saturated and unsaturated fatty acid, and $C_{20:3}/C_{20:4}$ ratio. Also, it affected to antigen-stimulated lymphocyte proliferation and macrophage phagocytic activities.

  • Two different sizes of olive founder were abruptly (within 30 min) exposed to hyposalinities from 35 to 0 $\textperthousand$ and to 15 $\textperthousand$ in a flow through seawater culture systems with 8 tanks (300 l/tank). Analysis of blood samples showed the following significant increase at 0 $\textperthousand$ S: hematocrit from 16.1 to 23.4% after 3 hr exposure and to 24.6% after 24 hours; plasma cortisol from 1.6 to 22.8 and 9.5 ng/$ml$ at 1 and 24 hi after exposure. At this salinity, survival decreased to 92 and 20 % after 72 and 144 hours of exposure, respectively. Levels of glucose, $Na^{+}and Cl$^{-}$, total protein and AST showed that the fish was under considerable stress. However, the fish showed no significant stress on exposure to 15 $\textperthousand$S.

  • Objectives : We investigated the effect of Dohongsamul-tang (DHSMT) on the production of various cytokines in lipopolysaccaride (LPS) stimulated peripheral mononuclear cells (PBMCs) from CI patients. Methods: Cell viability was determined using MTT assay. ELISA was carried out for investigating $TNF-{\alpha}$, $IL-1{\beta}$, IL-6, IL-8, IL-4, and $TGF-{\beta}$ 1 Results : The amount of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$, IL-6, IL-8, IL-4, and transforming growth factor(TGF)-${\beta}$ 1 in PBMC culture supernatant significantly increased in the LPS treated cells compared to unstimulated cells. We show that DHSMT inhibited the production of TNF-${\alpha}$, IL-1${\beta}$, IL-6, IL-8, and IL-4 induced by LPS in a dose dependent manner. The maximal inhibition rate of the TNF-${\alpha}$, IL-1${\beta}$, IL-6, IL-8, and IL-4 production by pretreatment of DHSMT (1.0mg/ml) was 38.52 ${\pm}$ 2.5% (P < 0.01), 44.02 ${\pm}$ 3.5% (P < 0.05), 45.32 ${\pm}$ 2.3% (P < 0.01), 42.30 ${\pm}$ 3.1% (P < 0.05), and 49.70 ${\pm}$ 3.1%(P &lt; 0.05), respectively. On the other hand, DMSMT significantly increased the LPS-induced TGF-${\beta}$ 1 production(P<0.05). Conclusions : Taken together. these results suggest that DHSMT might have regulatory effects on cytokine production, which might explain its beneficial effect in the treatment of CI.

  • Purpose : Acinetobacter baumannii is increasingly recognized as an important cause of nosocomial infection, especially in neonatal intensive care units. But little is known about the clinical significance and hospital epidemiology of Acinetobacter species other than A. baumannii. The objective of this study is to describe the clinical characteristics and epidemiology of septicemia due to Acinetobacter species other than A. baumannii. Methods : We retrospectively reviewed 11 cases of blood culture proven nosocomial infection which occured in our neonatal intensive care unit from $4^{th}$ to $24^{th}$, February, 2004. To establish epidemiological analysis, we performed environmental cultures and an antibiogram was obtained from susceptability tests of isolated Acinetobacter species. Results : Clinical manifestations including fever, poor feeding, abdominal distension, diarrhea, bloody stool passage, vomiting, tachypnea and apnea were similar to other infectious diseases. Benign clinical courses were compared with poor prognose, including a high mortality rate in septicemia due to A. baumannii. The major predisposing factor among our patients was the presence of a peripheral intravascular catheter. Antibiogram was similar, but surveillance cultures of environmental specimens failed to identify the source of infection. Conclusion : Acinetobacter species other than A. baumannii were often considered relatively avirulent bacteria, but could be pathologic organisms if cultured in patients with clinical symptoms.

  • In the study, we investigated the effect of Taurine-FTM, which is a commercially available fishery nutritional supplements complex, on anti-hepatotoxicity stressed with thioacetamide (TAA) and innate immune responses in olive flounder. To investigate the change in liver toxicity, firstly, TAA (30 ppm/100 g of fish) was intraperitoneally (i.p.) administered 12 hr after the intramuscular (i.m.) injection of Taurine-FTM (0.02 ml/100 g of fish)(Taurine/TAA). Secondly, Taurine-FTM was i.m. injected 24 hr after the administration of TAA (TAA/Taurine). Finally, TAA was administered simultaneously with Taurine-FTM (TAA+Taurine). All blood samples were collected 24 hr after injection. GOT level in group Taurine/TAA appeared similar to the control, whereas group TAA/Taurine and TAA+Taurine showed significantly increased (p<0.05) levels compared to the control. In GPT level, group Taurine/TAA and TAA/Taurine showed elevated levels compared to the control, whereas no significant difference was observed between group TAA+Taurine and the control. Serum ACH50 activity was significantly (p<0.05) augmented 24 hr after Taurine-FTM injection compared to the control group, whereas no significant increase was observed 48 hr after Taurine-FTM injection. On the other hand, serum lysozyme activity elevated in an acute stressed condition appeared significantly down-regulated 24 and 48 hr after Taurine-FTM injection compared to the control. In conclusion, i.m. injected Taurine-FTM augmented flounder serum complement activity and decreased a possible handling stress resulting in reducing a serum lysozyme activity and recovering hepatotoxicity. Thus, it is assumed that i.m. injection of Taurine-FTM mixed with antibiotics or available vaccines could be utilized as an anti-hepatotoxic recipe in fish culture industry.

  • A disease that manifested severe anemia of the gills occurred in the olive flounder (Paralichthys olivaceus), which was cultured for 5-6 months with a recirculation water system in the laboratory. Microscopic observations showed immature parasite in the gills and mature adults in the oral cavity. The matured parasite was 5.60-9.32 (7.42) mm in total length, with 4 pairs of clamps on the pedunculated haptor, which was separated from the body proper by a long isthmus. From the morphological observations of the larvae, it was identified as Neoheterobothirum hirame belonging to the monogenea. The average hematocrite of infected fish was 10.3 ± 2.8%, significantly lower than that of normal flounder 31.4 ± 4.2%. Histopathologically, fish infected with N. hirame exhibited reduced numbers of erythrocytes in blood vessels of the gill filament and lamellae, reduced red pulp area of the spleen, and hepatocyte atrophy. From the above results, the cause of severe anemia in olive flounder was identified as N. hirame infection. This study shows an example where the growth of pathogens can be a problem in the recirculation system due to low water exchange rate.
