Background: Various oncogenes related to cancer have been extensively studied and several polymorphisms have been found to be associated with breast cancer. The current report outlines analysis of germ-line polymorphisms for C677T, A1298C (MTHFR), Leiden, R2 (FV) and 5G/4G (PAI-1) in Turkish breast cancer patients. We studied 51 cases diagnosed with invasive ductal and operable with lymph node-positive breast cancer and 106 women as a control group. Materials and Methods: Peripheric blood-DNA samples were used for genotyping by StripAssay technique which is based on the reverse-hybridization principle and real-time PCR methods and results were compared statistically. Results: The frequency of the MTHFR gene 677T and 1298A alleles were significantly higher in cancer patients than in the healthy subjects. The T allele frequency in codon 677 was 2.3-fold and C allele frequency was 3.1-fold increased in BC when compared to the control group for the MTHFR gene. Both differences were statistically significant (OR: 2.295, CI: 1.283-4.106), p<0.006 and (OR: 3.131, CI:1.826-5.369), p<0.0001 respectively. The R2 allele frequency of FV gene was 5.1-fold increased in the current BC when compared to the control group and that difference was also statistically significant (OR: 5.133, CI: 1.299-20.28), p<0.02. Conclusions: The present data suggest that germ-line polymorphisms of C677T, C1298A for MTHFR and R2 for FV are associated in breast cancer and may be additional prognostic markers related to breast cancer survival. The results now need to be confirmed in a larger group of patients.

This paper describes the determination of bulk density and the discrimination of internal structure of red ginseng by nuclear magnetic resonance (NMR). The 102 red ginseng roots were tested for bulk density. The NMR properties measured by NMR parameters such as spin-lattice relaxation time ($T_1$) and spin-spin relaxation time ($T_2$) were determined using the low field proton NMR analyzer. Bulk density of red ginseng root showed a highly negative significant correlation (r=-0.8934) with the value of $T_1$, but a highly positive significant correlation (r=0.7672 and 0.5909) with the value of T21 (short T2) and T22 (long T2), respectively. Multiple regression equation, Y=-0.0069.$T_1$+0.3044.$T_{21}$-0.0156.$T_{22}$-0.6368, using the MNR parameter values of 80 red ginseng roots can effectively predict the bulk density of 22 red ginseng roots with the correlation coefficient of 0.9396 and the standard error of 0.086. The differences in the internal structure of normal and inside white part of red ginseng were easily found by the signal intensity of NMR image based on magnetic properties of proton nucleus.

To infer phylogenetic relationships between species of Trichaptum (Polyporaceae), RFLP analyses of PCR-amplified DNAs were accomplished. Regions coding for ITSs of nuclear SSU rRNA genes and for mitochondrial SSU rRNA genes from thirteen strains of four Trichaptum species (T. abietinum, T. biforme, T. fusco-violaceum, and T. laricinum) were amplified and digested with eight restriction enzymes. All the fragmentation patterns were characterized and coded as 0/1 for the absence/presence of fragments. A phylogenetic tree based on the combined data sets was constructed using the Dollo parsimony method. While every two strains of T. abietinum, T. biforme, T. fusco-violaceum, and T. laricinum formed an independent group, the other strains of T. abietimum and T. fusco-violaceum made mixed groupings among compared strains. It is inferred that T. abietinum and T. fusco-violaceum have more variations, possibly geographic or physiological ones, than other species in the genus.

홍마늘 추출물과 녹차, 식이섬유 및 녹차 식이섬유를 혼합한 3종의 복합물(R+T, R+F 및 R+TF)을 이용하여 고지방-콜레스테롤을 급이한 흰쥐에 대해 항비만 효과를 $in$ $vitro$ 및 $in$ $vivo$에서 측정하였다. 녹차 복합물(R+T) 및 녹차 식이섬유 복합물(R+TF)은 홍마늘 추출물(RG)보다 총 페놀 함량이 1.9~2.0배 높았으며, 콜레스테롤 흡착활성은 9.5~11.5배 높은 활성이었다. 실험군은 6군(정상군, 고지방-콜레스테롤 식이 급이군(HFC), R+T 급이군(HR+T), R+F 급이군(HR+F) 및 R+TF 급이군(HR+TF))으로 나누어 각 추출물을 식이에 1% 수준으로 4주간 급이 하였다. 실험군에서 최종 체중은 대조군에 비해 유의적인 감소를 보였으나, 식이효율은 대조군과 유의차가 없었다. 간장의 중량은 정상군에 비해 대조군이 2.0배 정도 증가되었으며, HR+T군과 HR+TF군에서 유의적으로 감소하였다. 내장지방과 부고환 주변지방 함량은 복합물 첨가군에서 대조군에 비해 유의적으로 감소하였다. 비만도 지수는 대조군에 비해 HR+TF군에서만 유의적으로 감소하였다. 총 지질, 총 콜레스테롤, 중성지질, LDL- 및 VLDL-콜레스테롤 등의 혈중 지질성분과 동맥경화 지수, 심혈관 질환 위험지수는 대조군에 비해 홍마늘 추출물 및 복합물 첨가군에서 유의적으로 감소하였으나, HR+T군, HR+F군 및 HR+TF군간에는 비슷한 수준이었다. GPT 활성은 복합물 첨가군간에 유의차가 없었으나, 홍마늘 추출물 첨가군보다는 유의적으로 낮은 활성이었다. 지질과 산화물 함량은 대조군에 비해 홍마늘 추출물과 복합물 첨가군에서 유의적으로 감소되었다. 항산화 활성은 HR+T군에서 가장 높았다. 따라서 홍마늘 복합물의 체내 지질 개선 및 항비만 효과는 시료 중의 녹차나 식이섬유의 총 페놀 함량 및 콜레스테롤 흡착활성에 기인된다고 생각된다.

Fifty five species of medicinal plant materials were tested for their antifungal activity in vitro against Rhizoctonia solani AG 2-1 and Trichoderma harzianum to select plant species that can be used to improve the biocontrol efficacy of T. harzianum. Six species were effective against R. solani AG 2-1 but were also antagonistic to T. harzianum, except for Cinnamomum loureirii stem bark (CSB). CSB inhibited mycelial growth of R. solani AG 2-1 by 73.7% but showed an inhibitory effect on mycelial growth of T. harzianum by only 2.2%. Scanning electron microscophs showed that the CSB treatment resulted in deformed R. solani AG 2-1 hyphal cells, and transmission electron microscophs revealed degenerated cell structures such as degenerated cytoplasm and disentangled cell wall and the accumulation of electron-dense inclusions (asterisks) in the CSB treatment. The biocontrol efficacy of radish damping-off increased greatly following the combined treatments of T. harzianum and CSB and the combined treatment increased efficacy from 6.4-23.1% to 37.1-87.3% compared with either treatment alone. CSB did not affect T. harzianum population growth, as it was almost the same in rice-bran peat medium (culture) amended with 0.1% and 1.0% CSB powder as in non-amended medium. The formulation of T. harzianum in rice-bran peat medium amended with CSB powder reduced the severity of radish damping-off by 80.6%, suggesting that T. harzianum and CSB can be formulated as a biocontrol product for the control of R. solani AG 2-1.

Triglyceride (TG) is known to be associated with inflammatory disease including atherosclerosis. In a variety of atherosclerosis models, T lymphocytes are localized in the earliest lesions of atherosclerosis. T cell associated cytokines such as $TNF-{\alpha}$ and $IFN-{\gamma}$ have pre-dominant inflammatory effects in chronic vascular diseases. In our previous study, we found that the expression of $TNF-{\alpha}$ and its receptor, $TNF-{\alpha}R$ was increased when Jurkat T lymphocyte cell lines were exposed to TGs. Therefore, experiments were conducted to determine which cell signaling pathway are involved in the increase of $TNF-{\alpha}$ and $TNF-{\alpha}R$ expression by TGs. To identify signal transduction pathways involved in TG-induced upregulation of $TNF-{\alpha}$, we treated TG-exposed Jurkat T cells with specific inhibitors for MEK1, PI3K, $NF-{\kappa}B$ and PKC. We found that inhibition of the MEK1 pathway blocked TG-induced upregulation of $TNF-{\alpha}$. However, the expression level of $TNF-{\alpha}R$ did not change with any signal transduction inhibitor. Based on this observation, we suggest that increase of exogenous TG induces increase of $TNF-{\alpha}$ expression through MEK1 pathway in Jurkat T cells. In addition, it was confirmed that the increase of $TNF-{\alpha}$ and $TNF-{\alpha}R$ expression by TGs occurs via different pathways.

크리핑벤트그래스는 골프코스의 퍼팅그린에서 주로 사용하고 있는 한지형잔디 초종이다. 크리핑벤트그래스 품종들은 형태적인 특성이나 유전적인 다양성이 협소하여 품종간 구분이 매우 어렵다. 따라서 이들 품종간 유전적인 다양성이나 골프코스 그린의 인터씨딩율에 대한 조사를 위해 SCAR marker를 개발하고자 본 연구를 수행하였다. penncross, penn A-4, crenshaw, L-93, CY-2, T-1 공시품종들에 대한 SCAR marker 개발을 위해 5개 RAPD primer에 대한 품종 간 구분이 가능한 특이적 band를 선발하였다. 선발한 특이적 band의 염기서열을 분석하여 품종별 SCAR primer를 제작하였다. 각 품종의 SCAR primer별로 특이적 band가 나타나는지에 대한 여부를 검정한 결과, penncross, penn A-4, crenshaw 품종의 SCAR primer는 6개 공시품종에서 동일한 크기의 band가 나타나 SCAR marker로써 활용이 어려웠다. 하지만 CY-2의 CY850F/R primer는 850bp, T-1의 T700F/R primer는 700bp, L-93의 L2900F/R는 2.9kb에서 특이적 band가 나타나 3개 품종별 SCAR marker로서 활용이 가능하였다. 따라서 본 연구에서 개발한 3개 품종별 SCAR marker를 활용하여 크리핑벤트그래스의 품종별 유전적 다양 및 골프코스 그린의 인터씨딩율 조사에 활용이 가능할 것으로 기대된다.
