Mucosa-associated lymphoid tissue(MALT) lymphoma is thought to originate from marginal zone B-cells. In the WHO classification, Extranodal marginal zone lymphoma of MALT is classified B-cell Non-Hodgkin lymphoma. Common sites of MALT lymphoma include stomach, lung and the ocular-adnexa. Although less common in other sites, it is the most common low-grade lymphoma of the breast, thyroid, bowel skin and soft tissue. No strong age or gender predominance exists in MALT lymphoma. Dissemination to other sites can occur. In the oral cavity, MALT lymphoma is rare. Herein, we present a case of intra-oral MALT lymphoma. 66 year-old woman without any background of immunodeficiency or autoimmune disease admitted department of oral & maxillofacial surgery in Ulsan university hospital for evaluation of long-standing mild upper lip swelling. The lesion was completely resected and biopsied. Histological and immunohistochemical stains(CD3, CD5, CD20, CD21, CK) findings were used to confirm the lesion. Bone marrow biopsy was done and no bone marrow involvement was found. She did not receive chemotherapy and radiotherapy after surgery. No recurrence has been noted in the 22 months to date.
Background: The purpose of this study was to investigate the effects of HBOT (hyperbaric oxygen therapy) on the pain, ROM (range of motion) and muscle fatigue recovery of DOMS (delayed onset muscle soreness). Design: Randomized Controlled Trial. Methods: Twenty-six subjects who are student in their 20s at a university participated in this study, these subjects were assigned into two groups, a control group (n=12) and an experiment group (n=14). The subjects in experimental group were intervened by HBOT (40 minutes, 1.3 ATA), while ones on control group weren't by any intervention after induced DOMS. Results: First, in the comparison of VAS (visual analog scale), there were significant variations with the period (p<0.001), interaction of period (p<0.05) and group (p<0.05). In the comparison of PPT (pressure pain threshold), there were significant variations with the period (p<0.001) and interaction of period (p<0.05). Second, in the comparison of ROM, there were significant variations with the period (p<0.001), interaction of period (p<0.001) and group (p<0.01). Third, in the comparison of CK (creatine kinase) and LDH (lactate dehydrogenase), there no signigicant variations with all measure variables. Conclusion: The above results indicated that HBOT were effective to decrease the pain and improve the ROM in DOMS. Also the statistical significant variations of blood factors of muscle fatigue were not found in this.
Arbuscular mycorrhizal fungi (AMF) are widespread soil endophytic fungi, forming mutualistic relationships with the vast majority of land plants. Biochar (BC) has been reported to improve soil fertility and promote plant growth. However, limited studies are available concerning the combined effects of AMF and BC on soil community structure and plant growth. In this work, a pot experiment was designed to investigate the effects of AMF and BC on the rhizosphere microbial community of Allium fistulosum L. Using Illumina high-throughput sequencing, we showed that inoculation of AMF and BC had a significant impact on soil microbial community composition, diversity, and versatility. Increases were observed in both plant growth (the plant height by 8.6%, shoot fresh weight by 12.1%) and root morphological traits (average diameter by 20.5%). The phylogenetic tree also showed differences in the fungal community composition in A. fistulosum. In addition, Linear discriminant analysis (LDA) effect size (LEfSe) analysis revealed that 16 biomarkers were detected in the control (CK) and AMF treatment, while only 3 were detected in the AMF + BC treatment. Molecular ecological network analysis showed that the AMF + BC treatment group had a more complex network of fungal communities, as evidenced by higher average connectivity. The functional composition spectrum showed significant differences in the functional distribution of soil microbial communities among different fungal genera. The structural equation model (SEM) confirmed that AMF could improve the microbial multifunctionality by regulating the rhizosphere fungal diversity and soil properties. Our findings provide new information on the effects of AMF and biochar on plants and soil microbial communities.
There are still debates in the literature on the relative benefits of blood cardioplegia and crystalloid cardioplegia in pediatric cardiac surgery. We performed a clinical trial to compare the myocardial protective effect between HTK solution and blood cardioplegic solution in congenital heart surgery. Material and Method: 15 patients who underwent HTK solution cardioplegia (group 1) and 15 patients who underwent blood cardioplegia(group 2) were included in this study. Preoperative and postoperative serial serum cardiac enzyme levels (troponin I, CK-MB, LDH) were measured in all patients. Clinical data were analyzed and compared between the two groups. Result: There were no differences in age and body weight between the two groups. Operative diagnosis included ventricular septal defect (VSD, n=4), atrial septal defect (ASD, n=1), tetralogy of Fallot (TOF, n=4), and other complex heart diseases (n=6) in group 1, VSD (n=7), ASD (n=5), and TOF (n=3) in group 2. Cardiopulmonary bypass times were 99.1$\pm$48.1 minutes in group 1, and 69.3$\pm$27.3 minutes in group 2 (p=0,02). Aortic clamping times were 52.1$\pm$23.6 minutes in group 1, and 37.9$\pm$20.5 minutes in group 2 (p=0.07). There was no mortality and spontaneous defibrillation was possible in all patients. No differences were observed in the serial enzyme levels between the two groups. There were no differences in the duration of inotropic support and ventilator time between the two groups. Conclusion: HTK solution provided comparable myocardial protection compared with blood cardioplegic solution. A single high dose of HTK solution may be safely and conveniently used for an extended periods as well in congenital heart surgery.

Background: Hypomagnesemia is a common complication after cardiac surgery with cardiopulmonary bypass. The purpose of this study was to assess the clinical beneficial effect of administration of magnesium sulfate in cardiac surgery. Material and Method: Thirty five patients scheduled for elective cardiac surgery were randomly assigned to magnesium group (n=20) which received magnesium sulfate in priming solution (1 g) and cardioplegic solution (1 g) or control group (n=15) which did not receive it. Arterial blood samples were drawn for measuring $Mg^{++}$ and electrolytes contents, blood gas analysis, CBC, total protein, albumin, blood urea nitrogen (BUN), creatinine, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin, tumor necrosis factor-${\alpha}$$(TNF-{\alpha})$, interleukin-6 (IL-6), interleukin-10 (IL-10), creatine phosphokinase (CpK), creatine kinase-MB (CK-MB), lactate dehydrogenase(LDH), troponin-1 (TNI), prothrombin time (PT) and activated pratial thromboplastin time level (aPTT). Venous blood samples were drawn before and after the operation for measuring activated clotting time level (ACT). Result: $Mg^{++}$ levels in magensium group were higher than those of control group at intraoperative and post-operative periods (p<0.05). dysrhythmias were lower in magnesium group (8 cases out of 17 patients, 46.4%) than in control group (10 cases out of 10, 100%, p=0.050). Conclusion: These results showed that administration of low dose magnesium sulfate during cardiac surgery prevented hypomagnesemia and lowered incidence of dysrhythmia.

Since the introduction of Israeli carp into Korea for farming in 1973, there are no breeding studies on developing Korea Israeli carp (domestic) so far. This study performed gene-based cross-breeding studies to restore genetic diversity of lowered Israeli carp through continuous inbreeding, and for rapid growth and better scales. This study produced four cross-breeding groups (F1) using Koean Israeli carp and Chinese Songpu mirror carp for the improvement of growth and scale of Israeli carp in Korea. And mating scheme for breeding groups was set in consideration of the morphological analysis and genetic distance of broodstock. In addition, this study used microsatellite markers and genotype data to analyze genetic diversity and parentage analysis. As a result, the average NA and HE values of Korean select broodstock are 8.3 and 0.743, and F1 is 13.0 and 0.764. This study shows that the genetic diversity of F1 has been recovered over Korean Israeli carp through breeding between Korean Israeli carp and Chinese Songpu mirror carp. Common Israeli carp in Korea reached 1.7 kg in 17 months, and improved Israeli carp reached to 2.2 kg. The KC (Korea×China, KC) group was 2.52 and broodstock group was 3.15. F1 showed lower scale score (0.63) than broodstock. The improved carp (F1; CK, KC) had 20% better scales than the parent group (F0), which improved 27% in weight and 25% in scales compared to common Israeli carp. The Israeli carp developed by the genetics-based breeding grew quicker and had improved genetic diversity and fewer scales, which will be of great value for Korean Israeli aquaculture industry due to good marketability.
Rheological properties of the dough added with milk proteins and gums was studied to investigate the possibilities as anti-staling agents. Also, physical properties of the resultant bread baked from the frozen dough after 8 weeks of storage at $-20^{\circ}C$ were examined. The 4 sets of their combinations of milk proteins and gums, $casein-{\kappa}-carrageenan$ (CK), casein-sodium alginate (CA), $whey-{\kappa}-carrageenan$ (WK), and whey-sodium alginate (WA), were added to dough to examine their possible anti-staling effects. Rheological properties of dough were evaluated, and physical properties of resultant bread baked from frozen dough after 8 weeks storage at $-20^{\circ}C$ were examined. Addition of all treatments increased gelatinization temperature and water absorption, and lowered miximum viscosities and extension of doughs, compared to the control. Doughs added with CA and WA showed longer development times than that of the control. Addition of WK and WA resulted in lowest dough extensions. Treated bread showed lower moisture content decrease during storage at $5^{\circ}C$ for 4 days. Breads baked with frozen doughs after 6 weeks storage at $-20^{\circ}C$ showed similar results. Although textural hardness of breads increased with storage at $5^{\circ}C$, CA- and WA-added breads were less affected, showing they effectively retarded staling of breads.
A monosomal karyotype (MK), defined as ${\geq}2$ autosomal monosomies or a single monosomy in the presence of additional structural abnormalities, was recently identified as an independent prognostic factor conveying an extremely poor prognosis in patients with acute myeloid leukemia (AML). In the present study, after excluding patients with t(15;17), t(8;21), inv(16) and normal karyotypes, 324 AML patients with cytogenetic abnormalities were the main subject of analysis. The incidences of MK were 13% in patients aged 15 to 60 years and 18% in those between 15 and 88 years old. MK was much more prevalent among elderly patients (p < 0.001) and was significantly associated with the presence of -7, -5, del(5q), abn12p, abn17p, -18 or 18q-, -20 or 20q- and CK (for all p < 0.001 except for abn12p p=0.009), and +8 or +8q was less frequent in MK+ AML(p=0.007). No correlation was noted between monosomal karyotype and FAB subtype (p > 0.05); MK remained significantly associated with worse overall survival among patients with complex karyotype (p=0.032); A single autosomal monosomy contributed an additional negative effect in OS of patients with structural cytogenetic abnormalities (P=0.008). This report presents the prevalence, feature and prognostic impact of MK among a large series of Chinese AML patients from a single center for the first time.

The antioxidant effect of Korean cabbage kimchi containing 20% of sea tangle (SK) was studied in the rats fed with high fat diet (HFD) for 8 weeks. The rats (n=40) were divided into four experimental groups as a high fat diet group (HFD), HFD supplemented either with Korean cabbage kimchi used as experimental control (HCK), with SK (HSK), or with J-kimchi (HJK) that was purchased at the local market. The amount of kimchi supplemented was 10%. DPPH radical scavenging activities of SK were significantly higher than those of CK. Kimchi suppressed the hepatic lipid peroxidation significantly, especially by HSK (p<0.05). Inhibition of thiobarbituric acid reactive substances (TBARS) formation in HSK was the greatest among the kimchi groups (p<0.05). The activities of $Cu{\cdot}Zn$-superoxide dismutase (SOD), Mn-SOD and catalase decreased significantly (p<0.05) by kimchi supplementation. SOD and catalase activities of HSK were found to be the lowest among the kimchi groups. The decreased enzyme activity in kimchi group might be due to the less amount of lipid peroxides produced in the rats fed kimchi diet. The lowest antioxidative enzyme activities observed in HSK were in line with those of hepatic POV and TBARS of HSK. Our findings confirmed that kimchi acted as an antioxidant in the high fat fed rats and its antioxidant effect was significantly increased by the addition of sea tangle.
Purpose: The purpose of this study was to search activated genes that could be related to radiation adaptive response (RAR) induced by low-level radiation from $^{99m}Tc$ in human cell lines. Methods: We used gene discovery array (GDA) and representational difference analysis (RDA) methods. $^{99m}Tc$-pertechnetate was added to $2{\times}106/mL$ NC-37 cells (human lymphoblastic cells) to make concentrations ranging from 148 MBq/mL to 148 Bq/mL by serial 10 fold dilutions. After 44 hours, 2 Gy gamma irradiation was given to them using a Cs-137 cell irradiator. Results: As compared to the control (Con) group to which no $^{99m}Tc$ was added, those cells to which 148 and 14.8 KBq of $^{99m}Tc$ were added showed significantly lower damage to chromosomes, which was evaluated by metaphase analysis. Cells with 148 KBq $^{99m}Tc$ (T148 group) showed most significant protection. Activated genes in the T148 group as compared to Con group were evaluated by GDA and GDA methods. GDA revealed genes of casein kinase 2 (CK2) beta chain, immunoglobulins (lg), human leukocyte antigen (HLA)-B, and two novel genes. Twenty RAR related clones were selected by RDA method. The size of those genes was from 234 to 603 base pairs. Conclusions: RAR was induced by low dose irradiation from $^{99m}Tc$ in NC-37 cell lines. Genes related to the response included CK2, lg, HLA-B in human lymphoblastic cell lines.
