  • Background: Surgery is the corner stone for the management of rectal cancer. The purpose of this study was to demonstrate the optimal time of surgical resection after the completion of neoadjuvant chemo-radiotherapy (CRT) in treatment of locally advanced rectal cancer. Materials and Methods: This study compared 2 groups of patients with locally advanced rectal cancer, treated with neoadjuvant CRT followed by surgical resection either 6-8 weeks or 9-14 weeks after the completion of chemo-radiotherapy. The impact of delaying surgery was tested in comparison to early surgical resection after completion of chemo-radiotherapy. Results: The total significant response rate that could result in functional preservation was estimated to be 3.85% in group I and 15.4% in group II. Some 9.62% of our patients had residual malignant cells at one cm surgical margin. All those patients with positive margins at one cm were in group I (19.23%). There was less operative time in group II, but the difference between both groups was statistically insignificant (P=0.845). The difference between both groups regarding operative blood loss and intra operative blood transfusion was significantly less in group II (P=0.044). There was no statistically significant difference between both groups regarding the intra operative complications (P=0.609). The current study showed significantly less post-operative hospital stay period, and less post-operative wound infection in group II (P=0.012 and 0.017). The current study showed more tumor regression and necrosis in group II with a highly significant main effect of time F=61.7 (P<0.001). Pathological TN stage indicated better pathological tumor response in group II (P=0.04). The current study showed recurrence free survival for all cases at 18 months of 84.2%. In group I, survival rate at the same duration was 73.8%, however none of group II cases had local recurrence (censored) (P=0.031). Disease free survival (DFS) during the same duration (18 months) was 69.4 % for patients in group I and 82.3% for group II (P=0.429). Conclusions: Surgical resection delay up to 9-14 weeks after chemo-radiation was associated with better outcome and better recurrence free survival.

  • The effects of chromium (Cr), dietary crude protein (CP) level, and potential interactions of these two factors were investigated in term of energy metabolism in lambs. Forty-eight 9-week-old weaned lambs (Dorper${\times}$Small-tail Han sheep, male, mean initial body weight = 22.96 kg${\pm}$2.60 kg) were used in a 2${\times}$3 factorial arrangement of supplemental Cr (0 ${\mu}g$/kg, 400 $\mu{g}$/kg or 800 ${\mu}g$/kg from chromium yeast) and protein levels (low protein: 157 g/d to 171 g/d for each animal, or high protein: 189 g/d to 209 g/d for each animal). Blood samples were collected at the beginning and end of the feeding trial. The lambs were then sacrificed and tissue samples were frozen for further analysis. Chromium at 400 ${\mu}g$/kg decreased fasting insulin level and the ratio of plasma insulin to glucagon, but these differences were not statistically significant; in contrast, chromium at 800 ${\mu}g$/kg increased the ratio significantly (p<0.05). Protein at the high level increased plasma tumor necrosis factor $\alpha$ (TNF-$\alpha$) level (p = 0.060). Liver glycogen content was increased significantly by Cr (p<0.05), which also increased liver glucose-6-phosphatase (G-6-Pase) and adipose hormone-sensitive lipase (HSL) activity. At 400 ${\mu}g$/kg, Cr increased muscle hexokinase (HK) activity. High protein significantly increased G-6-Pase activities in both the liver (p<0.05) and the kidney (p<0.05), but significantly decreased fatty acid synthase (FAS) activity in subcutaneous adipose tissue (p<0.05). For HSL activity in adipose tissue, a Cr${\times}$CP interaction (p<0.05) was observed. Overall, Cr improved energy metabolism, primarily by promoting the glycolytic rate and lipolytic processes, and these regulations were implemented mainly through the modulation by Cr of the insulin signal transduction system. High protein improved gluconeogenesis in both liver and kidney. The interaction of Cr${\times}$CP indicated that 400 $\mu{g}$/kg Cr could reduce energy consumption in situations where energy was being conserved, but could improve energy utilization when metabolic rate was increased.

  • Tomato spotted wilt virus (TSWV) occurred abruptly with a high incidence rate in 14 vegetable crops in Anyang area, Gyunggido in 2004. TSWV was identified by the symptoms on the indicator plants, immunocaptured reverse transcription-polymerase chain reaction (IC/RT-PCR), virion captured (VC)RT-PCR and RT-PCR using total RNA from the infected plants. Vegetable crops infected with TSWV included table tomato, cherry tomato, red pepper, lettuce, chicory, red leaf chicory, red mustard, dragon tongue, treviso, potato, perilla, sesame, pumpkin, and ssamchoo (hybrid of oriental cabbage and cabbage). The incidence of TSWV in fields ranged from 30 to $100\%$. TSWV usually produced necrosis, wilt and/or severe mosaic with typical single or double ring spots on the leaves. TSWV could be detected in Frankliniella occidentalis collected from the crops in the fields with $90\%$ rate by IC/RT-PCR.

  • As Kamisipjeondaebotang (KSD) extract is an herbal ingredient, safety is very important due to possible cell poisoning or heavy metal toxicity to organs when administered to humans or animals. Accordingly, this study examined the antioxidant and anti-inflammatory effects of KSD extract to confirm its medicinal safety by using RAW 264.7 cells after heavy metal screening, functional index test of the liver and kidney, and cell survival rate test. Heavy metals were not found in KSD extracts or were less than standard amounts. Liver function indices such as aspartate aminotransferase and alanine aminotransferase revealed low values and kidney function indices such as creatinine and blood urea nitrogen were not significantly different from the normal group. This proved the safety to the human. RAW 264.7 cells showed no poisoning compared to the control group in terms of survival rate. Regarding the antioxidant effect of KSD extract, 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity and 2,2'-azino-bis(3-ethylbenzothiazo-line-6-sulphonic acid) radical scavenging activity increased at concentrations over $10{\mu}g/mL$. The anti-inflammatory effect of KSD extract significantly decreased based on the amount of nitric oxide at concentrations of 10 and $100{\mu}g/mL$ compared to the control group. Expression of interleukin (IL)-$1{\beta}$ and IL-6 decreased in a concentration-dependent manner. There was no significant difference in tumor necrosis factor-${\alpha}$ level. Based on the results, KSD can be regarded as a safe antioxidant with anti-inflammatory effects for fracture treatment.

  • Purpose: Purpura fulminans is a rare but rapidly progressive, serious, often life-threatening disorder in childhood, which is complicated with septic shock or disseminated intravascular coagulopathy during acute infection. It occurs first as acute-onset petechial rash, and spreads rapidly into full thickness skin and soft tissue necrosis. In the past, it had high mortality rate, up to 80%, but recently, survival rate has increased due to early diagnosis, and rapid advancement of critical care and antibiotics. From our experiences of PF management, we would like to review the pathophysiology and suggest the surgical treatment guideline about meningococcal induced purpura fulminans. Methods: Two cases of purpura fulminans over the last 3 years were reviewed retrospectively about reconstructive management. After they were treated resuscitative management initially by the critical intensive care, reconstructive surgery was performed by plastic surgeon as soon as the patients were vitally and mentally stable. Results: There were 6 procedures in case 1, and 3 procedures in case 2. The mean delayed period from admission with sepsis to the first surgical debridement was 24 days and 42 days, respectively. Total hospitalization period was 103 days and 69 days, respectively. All of them were treated with debridement and split thickness skin graft, but delayed debridement was superior to early one in the point of preserving much more tissues. Conclusion: From our experience, we suggest that conservative therapy to the wounds appears to be the best tool in the initial vitally unstable period in order to preserve as much tissues and functions as possible if no active inflammation and compartment syndrome are detective.

  • The Korean genuine medicine, 'Gigukjihwangtanggami (GJT)' has long been used clinically for hypertension and various cerebrovascular diseases. However, experimental study has been carried out very little. Recently cytokines involved in the regulation of inflammatory reactions and immune responses may play an important role in the pathogenesis of cerebral infarction (CI). The aim of this study is to investigate the effect of GJT on the production of pro-inflammatory cytokines and anti-inflammatory cytokines in peripheral blood mononuclear cells (PBMCS) stimulated with lipopolysaccaride (LPS) from Cl patients. The amount of tumor necrosis $factor-{\alpha}\;(TNF-{\alpha}),\;interleukin-1{\beta}\;(IL-1{\beta})$, IL-6, IL-8, IL-4 and IL-10 in PBMC culture supernatant was significantly increased in the LPS treated cells compared to unstimulated cells. GJT inhibited the production of $TNF-{\alpha},\;IL-1{\beta}$, IL-6 and IL-8 induced by LPS. The maximal inhibition rate of the $TNF-{\alpha},\;IL-1{\beta}$, IL-6 and IL-8 production by pretreatment of GJT (1 mg/ml) was $57.32{\pm}2.5%$ (p.0.05), $42.02{\pm}3.5%$ (p.0.05), $40.02{\pm}2.3%$ (p.0.05) and $48.02{\pm}3.1$, (p.0.05), respectively. In the Other hand, GJT increased the production of IL-4 and IL-10. The maximal increase rate of the IL-4 and IL-10 production by pretreatment of GJT (1 mg/ml) was $42.4{\pm}3.3%$ (p.0.05) End $56.4{\pm}2.9%$ (p.0.05), respectively. Taken together, these results indicate that GJT Ray have regulatory effects on the cytokine production and suggest that GJT might use clinically for the treatment of CI.

  • Objective: The demands for measures to improve disease resistance and productivity of livestock are increasing, as most countries prohibit the addition of antibiotics to feed. This study therefore aimed to uncover functional feed additives to help enhance livestock immunity and disease resistance, using Acanthopanax sessiliflorus fruit extract (ASF). Methods: ASF was extracted with 70% EtOH, and total polyphenolic and catechin contents were measured by the Folin-Ciocalteu and vanillin assay, respectively. The 3D4/31 porcine macrophage cells ($M{\Phi}$) were activated by phorbol 12-myristate 13-acetate (PMA), and cell survival and growth rate were measured with or without ASF treatment. Flow-cytometric analysis determined the lysosomal activity, reactive oxygen species levels (ROS), and cell cycle distribution. Nuclear factor kappa B ($NF-{\kappa}B$) and superoxide dismutase (SOD) protein expression levels were quantified by western blotting and densitometry analysis. Quantitative polymerase chain reaction was applied to measure the lipid metabolism-related genes expression level. Lastly, the antibacterial activity of 3D4/31 $M{\Phi}$ cells was evaluated by the colony forming unit assay. Results: ASF upregulated the cell viability and growth rate of 3D4/31 $M{\Phi}$, with or without PMA activation. Moreover, lysosomal activity and intracellular ROS levels were increased after ASF exposure. In addition, the antioxidant enzyme SOD2 expression levels were proportionately increased with ROS levels. Both ASF and PMA treatment resulted in upregulation of $NF-{\kappa}B$ protein, tumor necrosis factor $(TNF){\alpha}$ mRNA expression levels, lipid synthesis, and fatty acid oxidation metabolism. Interestingly, co-treatment of ASF with PMA resulted in recovery of $NF-{\kappa}B$, $TNF{\alpha}$, and lipid metabolism levels. Finally, ASF pretreatment enhanced the in vitro bactericidal activity of 3D4/31 $M{\Phi}$ against Escherichia coli. Conclusion: This study provides a novel insight into the regulation of $NF-{\kappa}B$ activity and lipid metabolism in $M{\Phi}$, and we anticipate that ASF has the potential to be effective as a feed additive to enhance livestock immunity.

  • Objective: Gram-negative bacteria lipopolysaccharide (LPS) has been reported to be associated with uterine impairment, embryonic resorption, ovarian dysfunction, and follicle retardation. Here, we aimed to investigate the toxic effects of LPS on the maturation ability and parthenogenetic developmental competence of bovine oocytes. Methods: First, we developed an in vitro model to study the response of bovine cumulusoocyte complexes (COCs) to LPS stress. After incubating germinal vesicle COCs in $10{\mu}g/mL$ of LPS, we analyzed the following three aspects: the expression levels of the LPS receptor toll-like receptor 4 (TLR4) in COCs, activities of intracellular signaling protein p38 mitogen-activated protein kinase (p38 MAPK) and nuclear factor-kappa B (NF-${\kappa}B$); and the concentrations of interleukin (IL)-$1{\beta}$, tumor necrosis factor (TNF)-${\alpha}$, and IL-6. Furthermore, we determined the effects of LPS on the maturation ability and parthenogenetic developmental competence of bovine oocytes. Results: The results revealed that LPS treatment significantly elevated TLR4 mRNA and protein expression levels in COCs. Exposure of COCs to LPS also resulted in a marked increase in activity of the intracellular signaling protein p-p38 MAPK and NF-${\kappa}B$. Furthermore, oocytes cultured in maturation medium containing LPS had significantly higher concentrations of the proinflammatory cytokines IL-$1{\beta}$, TNF-${\alpha}$, and IL-6. LPS exposure significantly decreased the first polar body extrusion rate. The cytoplasmic maturation, characterized by polar body extrusion and distribution of peripheral cortical granules, was significantly impaired in LPS-treated oocytes. Moreover, LPS exposure significantly increased intracellular reactive oxygen species levels and the relative mRNA abundance of the antioxidants thioredoxin (Trx), Trx2, and peroxiredoxin 1 in oocytes. Moreover, the early apoptotic rate and the release of cytochrome C were significantly increased in response to LPS. The cleavage, morula, and blastocyst formation rates were significantly lower in parthenogenetically activated oocytes exposed to LPS, while the incidence of apoptotic nuclei in blastocysts was significantly increased. Conclusion: Together, these results provide an underlying mechanism by which LPS impairs maturation potential in bovine oocytes.
