Acute kidney injury (AKI) can result in mortality or progress to chronic kidney disease in hospitalized patients. Although serum creatinine has long been used as the best biomarker for diagnosis of AKI, it has some clinical limitations, especially in children. New biomarkers are needed for early diagnosis, differential diagnosis, and reliable prediction of prognosis in AKI. Up to the present, candidate AKI biomarkers include neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), interleukin-18 (IL-18), livertype fatty acid-binding protein (L-FABP), matrix metalloproteinase-9 (MMP-9), and Nacetyl-$\ss$-D-glucosaminidase (NAG). However, whether these are superior to serum creatinine in the confirmation of diagnosis and prediction of prognosis in AKI is unclear. Further studies are needed for clinical application of these new biomarkers in AKI.

된장을 극성이 다른 유기용매로 분획하여 Ames test를 이용한 항돌연변이성 효과를 알아보고자 하였고 Yac-1과 sarcoma-180암세포들의 증식에 대한 된장 분획물의 효과를 측정함과 동시에 면역과정의 생물학적 작용과 대사적 변화를 유도하는 interleukin-2 (IL-2)의 생성에 대한 효과도 검토하였다. AFB$_1$에 대한 돌연변이 억제효과는 된장의 메탄을 추출물을 2.5 mg/plate 농도로 첨가했을 때 84%의 돌연변이 저해효과를 나타내었고 같은 첨가농도에서 메탄을 분획물들중 디클로로메탄 분획물과 에틸아세테이트 분획물은 각각 96%, 97%로 상당한 항돌연변이 효과를 나타내었다. 직접돌연변이원인 MNNG의 경우, AFBI에 비해 돌연변이 저해효과가 다소 떨어지지만 그 중에서도 에틸아세테이트 분획물이 75%로 가장 높은 항돌연변이 효과를 나타내었다. Sarcoma 180 cell 암세포 증식 억제효과 실험에서 디클로로메탄 분획물(첨가농도 15.6 ${\mu}$g/ml)은 60%의 저해효과를 나타내면서 농도 의존적으로 그 저해효과가 컸으며 250 ${\mu}$g/ml 농도에서는 80%의 저해효과를 관찰 할 수가 있었다. 에틸아세테이트분회물의 경우 디글로로메탄 분회물에 비해 다소 낮은 저해효과를 나타내었지만 250 ${\mu}$g/ml 농도에서 약 60%의 세포독성 효과를 나타내었다. 디클로로메탄 분획물과 에틸아세테이트 분획물에 의한 면역 활성 증진 효과를 검토한 결과, 디글로로메탄 분획물은 첨가농도 1 ${\mu}$g/ml에서 94%로 Yac-1표적세포를 사멸시켰으며 에틸아세테이트 분획물도 동일 농도에서 96%의 억제효과를 나타내었다.

Probiotics are known to provide the host with immune-modulatory effects and are therefore of remarkable interest for therapeutic and prophylactic applications against various disorders, including inflammatory diseases. Weissella cibaria JW15 (JW15) has been reported to possess probiotic and antioxidant properties. However, the effect of JW15 on inflammatory responses has not yet been reported. Therefore, the objective of the current study was to evaluate the anti-inflammatory potential of JW15 against lipopolysaccharide (LPS) stimulation. The production of pro-inflammatory factors and the cellular signaling pathways following treatment with heat-killed JW15 was examined in LPS-induced RAW 264.7 cells. Treatment with heat-killed JW15 decreased nitric oxide and prostaglandin $E_2$ production via down-regulation of the inducible nitric oxide synthase and cyclooxygenase-2. In addition, treatment with heat-killed JW15 suppressed the expression of pro-inflammatory cytokines, interleukin $(IL)-1{\beta}$, IL-6, and tumor necrosis factor-${\alpha}$. The anti-inflammatory properties of treating with heat-killed JW15 were associated with mitogen-activated protein kinase signaling pathway-mediated suppression of nuclear factor-${\kappa}B$. These results indicated that JW15 possesses anti-inflammatory potential and provide a molecular basis regarding the development of functional probiotic products.

Background: The megakaryopoiesis and platelet production is regulated by several hematopoietc factors such as thrombopoietin (TPO), interleukin-11 (IL-11) and interleukin- 3 (IL-3). IL-11 is a potent stimulator of megakaryopoiesis in vivo, and acts primarily as a megakaryocyte maturation factor in vitro and it can act synergistically with IL-3 and TPO. We performed this study to investigate the effects of recombinant human IL-11 (rhIL-11) with other hematopoietic factors on megakaryocyte colony formation in vitro. Methods: CD34+ cells were separated from umbilical cord blood and megakaryocyte colonies using MegaCult Assay Kit were cultured with rhIL-11, recombinant human IL-3 (rhIL-3), and recombinant human TPO (rhTPO) for 7 and 14 days. The number and percentage of CD34+ and CD41a+ cells were determined by flowcytometry. Results: The number of CD41a+ cells were $0.54{\pm}0.05{\times}10^4$ (rhIL-11 100 ng/ml), $5.32{\pm}0.23{\times}10^4$ (rhIL-3 100 ng/ml), and $8.76{\pm}0.15{\times}10^4$ (rhTPO 50 ng/ml) of total expanded cells during the culture of the purified CD34+ cells in liquid phase for 7 days. The number of CD41a+ cells were increased to $7.47{\pm}0.69{\times}10^4$ (rhIL-3+ rhIL-11), $11.92{\pm}0.19{\times}10^4$ (rhTPO+rhIL-11) of total expanded cells, respectively, during the culture of the purified CD34+ cells in liquid phase for 7 days in the presence of rhIL-11 (100 ng/ml). When the purified CD34+ cells were cultured in semisolid mediaincluding various concentration of rhIL-11, the megakaryocyte colonies were not formed. When the purified CD34+ cells were cultured with rhIL-11 and rhTPO or with rhIL-11 and rhIL-3, the number of megakaryocyte colonies were increased compared with rhTPO or rhIL-3 alone. Conclusion: These results indicate that IL-11 exerts a potent proliferative activity to colony forming unit-megakaryocyte from human umbilical cord blood, and it acts with other hematopoietic factors synergistically.

There have been no published studies concerning the anti-inflammatory effects of corn silk on colon cancer cells. Thus, this study was conducted to investigate the effect of corn silk extract containing high levels of maysin on inflammation and its mechanism of action in colon cancer cells. SW 480 human colon cancer cells were treated with $1{\mu}g/mL$ of lipopolysaccharide (LPS) to induce inflammation, and next they were treated with different concentrations of corn silk extract (0, 5, 10 and $15{\mu}g/mL$). The concentrations of nitric oxide (NO) were determined. The mRNA expressions of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), tumor necrosis factor ${\alpha}$ ($TNF-{\alpha}$), interleukin-1beta ($IL-1{\beta}$) and interleukin-6 (IL-6), were determined. Western blot analysis was performed to determine the protein expressions of nuclear factor-kappa B ($NF-{\kappa}B$) and mitogen-activated protein kinases, and the latter consists of extracellular signal-related kinase (ERK), c-jun NH2-terminal kinase (JNK) and p38 MAP kinase (p38). The concentration of NO and the mRNA expression of iNOS were significantly and dose-dependently decreased in the corn silk-treated groups (P<0.05). The mRNA expression of $TNF-{\alpha}$, $IL-1{\beta}$ and IL-6 were significantly increased in the LPS-treated group (P<0.05), but these expressions were significantly and dose-dependently decreased in the corn silk treated groups (P<0.05). The protein expressions of $NF-{\kappa}B$ (in a dose-dependent fashion), ERK (at 10 and $15{\mu}g/mL$), JNK (at $15{\mu}g/mL$) and p38 (at 10 and $15{\mu}g/mL$) were significantly decreased with corn silk treatments (P<0.05). In conclusion, corn silk extract containing high levels of maysin seems to inhibit the LPS-induced inflammatory responses in SW480 colon cancer cells via the $NF-{\kappa}B$ pathway.
