A seed pelleting technique was developed for easy handling of small sesame seeds (Chinbaeckkae) and for direct seeding in field. The mixture of pelleting material, binder(sodium alginate) and seeds were dropped in 100mM CaCl$_2$ solution. Charcoal was appeared as a best material among all to make pellets with the characters of hardness, breakdown, destruction rate and germination percentage. Zeolite formed the hardest pellet seeds among the materials and 1~3 seeds contained in a pellet on the treatment of 87g of sesame seeds mixed in 1$\ell$ CaCl$_2$ solution was estimated optimum rate of seed mixure with few appearance of seedless pellet. The moisture absorption rate was greater in the order of peat＋charcoal > peat > charcoal > zeolite. Germination percentage of pelleted seeds with charcoal was the best and similar to that of common non-treated seeds. Germination percentage of pelleted seeds by sowing depth of exposing a quarter of pellet seeds on the surface of vermiculite germination test box and were 92％ in charcoal treatment and was the best among all released materials.

유전체 전장 연관분석 (GWAS)은 단일염기다형성(SNP)의 유전자형과 표현형 간의 통계적인 연관성을 분석함으로써 품종 선발용 SNP Marker 개발에 응용되고 있다. 본 연구에서는 Tano Red와 Ruby seedless 교배실생 278 계통을 대상으로 여러 과실 특성에 따른 관련 SNP를 동정함으로써 육종 선발에 필요한 DNA marker 개발에 필요한 기초 유전 자료를 얻고자 하였다. 한 계통 당 5~10개의 포도알을 선택하여 과립중, 과육탄성, 과피탄성, 과육경도, 과피경도, 과립당 종자갯수, 과립당 종자무게 및 인장강도를 측정하였다. 각 개체는 Genotyping by sequencing (GBS) 방법으로 Sequencing하여 Reference genome (Vitis vinifera PN40024 12X v2.)과 mapping 하였다. MAF (Minor allele frequency) >5%, Missing Data <30% 의 조건을 가진 SNPs 만 1차 선발하여 TASSEL과 GAPIT 프로그램으로 GWAS 분석을 하였다. Manhattan plot 결과 과립중 형질에서는 33개, 과립당 종자무게 25개와 인장강도에서는 20개의 통계학적으로 유의한 SNPs 가 선발되었고, 특이적으로 이들 모두 18번 염색체에서 발견되었다. 그러나 나머지 형질에서는 유의한 차이를 보이는 SNPs를 선발하지 못하였다. 과실의 인장강도는 수확 후 저장성과 유통과정에 영향을 미치기 때문에 Marker 개발을 통한 품종선별이 중요하다. 향후 이러한 특성과 본 연구를 통해 동정된 SNPs 의 상관관계를 구체적으로 연구하여 Marker 개발에 활용하고자 한다.

The experiment was conducted to evaluate the effect of fruit skin spray of the lime fertilizer in 'Campbell Early' grapes. The T-N, P, K, Ca and Mg of fruit skin and cluster weight, berry weight, cluster length showed no difference between control and lime fertilizer. But soluble solids in fruit was reduced by fruit skin spray of liquid calcium fertilizer extracted from oyster shell after bagging(LCaB). The anthocyanin content of fruit skin was decreased by air-slaked lime(HCa) and LCaB treatment. Also, occurrence of fruit skin bloom was significantly reduced by HCa and oyster shell powder(OS-CaP) treatment. The berry firmness was significantly increased through liquid calcium fertilizer extracted from oyster shell(LCa) and HCa treatment. Conspicuously, berry elasticity was rather decreased by OS-CaP treatment. However, there was no difference of weight loss of fruit among treatments during room temperature storage.

This research focused on determining the effectiveness of cluster and/or flower thinning in highbush 'Jersey' blueberry on the yield and fruit quality. The total yield and quality of fruit were compared between thinning methods of control (no thinning), 1/3 cluster thinning, 1/3 cluster thinning + 1/2 flower thinning, 2/3 cluster thinning, and 2/3 cluster thinning + 1/2 flower thinning per each bearing shoot, respectively. Thinning strength significantly affected the yield of bearing shoot and, thus, total yield of control and 1/3 cluster thinning was higher than others. Both cluster and flower thinning, however, significantly affected the fruit growth resulting in the increase of fruit weight, length and width. Even total yield was similar between control and 1/3 cluster thinning, more larger fruit (> 1.6 g) were produced by 1/3 cluster thinning treatment, indicating that flower and/or cluster thinning contributed to the increase of individual fruit growth. Unlike fruit growth, fruit quality was less affected except total soluble solid contents. Total soluble solid level significantly increased in treatments (2/3 cluster thinning, 2/3 cluster thinning + 1/2 flower thinning) with yield decrease. No significant difference in levels of acidity and firmness of fruit was found. Results indicated that fruit growth and total yield of highbush blueberry was more influenced by the thinning strength regardless of cluster or flower than internal quality of fruit such as solid and acid levels.

Granulocytic sarcoma is a manifestation of myelogenous leukemia, which means a solid mass consisting of primitive precursors of the granulocytic series of white blood cells. We present CT and MR imaging findings of bilateral sino-orbital granulocytic sarcoma in a 22-month-old boy. The mass involved bilateral orbital fossa which resulted in bilateral proptosis. Moreover, the mass extended to the almost skull base including paranasal sinuses, maxilla, temporal bone, zygomatic bone, sphenoid bone, ethmoid, and palatine bone. The adjacent dura was continuously thickened and the lower half of cavernous sinus was also involved. The patient was diagnosed as AML (M5) with t(8,21) translocation through a chromosome study from the bone marrow.

Granular cell tumors (GCT) are uncommon benign neoplasms. Their location is mostly in the the skin, tongue, and breast; appearance in other parts of the body is rare, but it has been reported. They have also been reported to occur synchronously in multiple organs and metachronously in a single organ. The incidence of GCTs in the tracheobronchial tree is unknown and pulmonary GCTs are uncommon, with approximately 100 reported cases in the literature. We present the case of a 33-year-old man with a granular cell tumor of the left main bronchus. The tumor was found at bronchoscopy performed to exclude suspected endobronchial mass with symptoms of pneumonia. Biopsies revealed the histological pattern of a benign granular cell tumor. He underwent resection of the left main bronchus followed by end to end anastomosis of left main bronchus. He has not had any recurrence of the tumor during the 1 year follow-up.

배 경: Pituitary adenylate cyclase-activating polypeptide (PACAP)은 양의 시상하부에서 추출된 신경펩타이드 호르몬으로 난소에도 존재하여 배양된 과립막 세포에서 스테로이드합성과 cyclic AMP 형성을 촉진함이 보고되었다. 목 적: 흰쥐 난소를 실험 모델로 사용하여 배란시 황체화호르몬 (luteinizing hormone; LH)에 의해 유도된 PACAP과 PACAP 수용체의 유전자 발현양상과 신호 전달경로를 규명하고자 하였다. 재료 및 방법: 미성숙 흰쥐의 배란전 난포를 체외 배양하면서 LH로 처리하고 PACAP 및 PACAP수용체의 유전자 발현을 보기 위해서는 Northern blot 분석과 in situ hybridization (ISH)을, 그리고 단백질 수준의 PACAP 검색을 위해서는 enzyme linked immunosorbent assay (ELISA) 분석을 이용하였다. 결 과: LH 처리 후 Northern blot상의 PACAP 유전자 발현은 6~9시간에 일시적으로 최고치에 도달하였으며 ISH로 보아 과립막 세포에서 발현됨을 알 수 있었다. ELISA 분석 상 PACAP 단백질도 LH처리 후 6~12시간에 최고치를 나타내었으며, PACAP 수용체 mRNA 역시 3~9시간에 최고치로 과립막 세포에서 발현되었다. Adenylate cyclase (AC) 억제제인 MDL12330A 처리시 LH로 발현된 PACAP mRNA가 감소되며, AC의 활성제인 forskolin 처리에는 LH시와 유사한 PACAP mRNA의 발현양상을 나타내었다. 그러나 protein kinase C (PKC)의 억제제인 chelerythrine과 2-0-tetradecanolphorbol-13-acetate (TPA) 처리로는 PACAP 의 유전자 발현에 영향을 주지 못하였다. 5-lipoxygenase의 억제제인 MK886이나 nordihydroguaiaretic acid (NDGA)로 처리한 결과 LH로 유도된 PACAP 유전자의 발현이 감소되었으나, cyclooxygenase의 억제제인 indomethacin은 별로 영향을 주지 못하였다. MEK와 p38의 억제제인 PD98059와 SB203580도 LH로 촉진 된 PACAP의 유전자 발현을 농도 의존적으로 억제하였다. 결 론 : 배란전 난포에서 PACAP과 PACAP 수용체의 유전자 발현은 모두 LH의 폭발적 분비에 의해 유도되어 일시적으로 과립막 세포에서 나타나 배란을 위한 국소적인 조절 작용을 할 것으로 추정되며, LH로 촉진된 PACAP 유전자 발현을 위한 신호전달은 cAMP-PKA, lipoxygenase 및 MAP kinase 경로를 통하는 것으로 사료된다.

The texture profile of frankfurter sausages was carried out by comparing the domestic(A) and imported(B) products. Fourteen character notes were identified: elasticity, surface moisture, surface smoothness, center hardness, skin toughness, cohesiveness, denseness, chewiness, moisture release, cohesiveness of mass, lumpiness, graininess, skin separation, and oiliness. Reference scales and the $0{\sim}3$ point numerical scaling method were also established. Panelists evaluated sausage A harder than the sausage B. It had higher skin separation and elasticity scores requring more chewing. Sausage B had lower surface moisture and cohesiveness of mass, but higher moisture release and graininess. Panelists commented that the sausage B were oilier but had milder tastes.
