방울토마토의 수경재배 중 붕소+칼슘+규소 및 칼슘+규소의 복합 엽면시비가 수확 후 품질과 MAP 저장 중 저장성에 미치는 영향을 알아보고자 본 연구를 실시하였다. 엽면시비한 방울 토마토(‘Unicorn’)는 반숙 과상태에서 수확하여 산소투과성 필름으로 포장한 5oC, 11oC, 그리고 24oC에서 25일, 15일, 10일간 저장하였다. 붕소+칼슘+규소 복합처리한 방울토마토가 3가지 저장온도 모두에서 호흡과 에틸렌 발생이 억제되어 MAP 저장중 가장 낮은 생체중 감소와 가장 높은 외관상 품질을 보였다. 수확 후 조사한 방울토마토의 경도, 산도, 비타민 C 함량은 붕소+칼슘+규소 복합처리에서 가장 높았으며, 3가지 온도 모두에서 MAP 저장 후에도 모두 높게 유지되었다. 그러나 과피색, 라이코펜 함량과 당도는 수확 후에는 엽면시비 처리로 차이가 없었으나, 3가지 온도 모두 붕소+칼슘+규소 복합처리에서 가장 낮은 수치를 보였다. 이상의 결과로 볼 때 붕소+칼슘+규소 복합처리는 방울토마토의 수확후 생리 작용을 억제하고 경도, 산도, 비타민 C 함량을 높여 저장성을 향상시키는 것으로 판단되었다

Adhesive capsulitis of the shoulder is a common cause of pain that occurs during shoulder movement, thereby restricting shoulder rotation in clinical practice. Although most patients respond to pain relief treatment (NSAID or corticosteroids) by improving their range of motion, it remains poorly understood without any definitive treatment algorithm. In addition to immune cells, synoviocytes, chondrocytes and osteoblasts in the joint are known to produce pro-inflammatory mediators such as reactive oxygen species (ROS), inflammatory cytokines and lipid mediators, presumably contributing to the pathogenesis of osteoarthritis (OA) and adhesive capsulitis. Although inflammation and also fibrosis are proposed to be the basic pathological changes of a frozen shoulder, there is a lack of information regarding the downstream targets of the pro-inflammatory ROS signaling pathway in the synoviocytes and also how these ROS targets are modulated at the transcription level by a corticosteroid - dexamethasone. In this study, we used human fibroblast like synoviocytes (HFLS) to characterize the signaling targets of ROS by employing a human DNA microarray tool and studied the role of dexamethasone in this process. Our data suggest that several genes such as FOS, FOSB and NFkBIZ, which are known to be involved in pro- or anti- inflammation response, are modulated at the transcription level by ROS and dexamethasone.

담도 과오종과 선천성 간섬유증은 태생기에 간판 기형에 의해 생기는 섬유 낭성 질환에 속한다. 담도 과오종은 증상 을 유발하지 않고 우연히 발견되는 질환이지만, 선천성 간섬 유증은 25%에서 담관염이 발생하고 증상이 발생하면 항생 제 투여부터 수술까지 적극적 치료가 필요하다. 저자들은 복부 영상 소견으로 담도 과오종으로 진단하고 경과 관찰하던 64세 남자가 2년간 반복적인 담관염이 발생한 원인을 찾기 위해 시행한 간 생검에서 담도 과오종과 선천성 간섬유증이 병합된 것으로 진단한 증례를 경험하여 문헌고찰과 함께 보고한다.

The study aimed to evaluate the usability of sterile bag collection (SBC) urinalysis and urine culture for diagnosing urinary tract infections (UTI). Urine culture is key for diagnosing UTI, and transurethral catheterization (TUC) or suprapubic aspiration is recommended for non-toilet-trained children. Although urine testing using SBC is non-invasive and easy, UTI can be diagnosed only if other criteria including clinical symptoms and positive urinalysis results are met. This study included 228 infants who were hospitalized for unexplained fever from October 2015 to June 2016. TUC culture, SBC urinalysis, and urine culture were performed for all patients. UTI was diagnosed when the TUC culture results met the criterion of ≥104 colony-forming units (CFU)/mL. When UTI diagnosis was made based on SBC urine colony counts ≥105 CFU/mL, the false-positive and false-negative rates were 6.3% and 70.0%, respectively. When the criterion was set as ≥104 CFU/mL, they were 23.7% and 30.0%, respectively. When both the criteria of ≥105 CFU/mL and positive urinalysis results were met, the false-positive rate was 2.4%, and the false-negative rate was 80%. Our results suggest that diagnosing UTI using SBC urinalysis and urine culture is not useful in infants with unexplained fever.

Background : This text was conducted to compare the difference of fatty acid by part and ha bitat of Glehnia littoralis in Korea Midwest. Methods and Results : In Glehnia littoralis, Saturated fatty acid consisted of palmitic acid, ste aric acid, and unsaturated fatty acid was oleic acid, linoleic acid, linolenic acid. Content of w hole fatty acid was the most as 42.8% linoleic acid, and stearic acid was less best as 2.9%. Other fatty acid were oleic acid 27.1%, palmitic acid 15.3%, linolenic acid 11.9%. Fatty acid by plant part it was the most in leaf that linoleic acid (31.4%), and it was the most in root t hat linoleic acid (68.3%), and it was the most in breed that oleic acid (65.5%). Fatty acid by natural habitat contained in Incheon area located in high latitude more than Taean area. Conclusions : In Glehnia littoralis of Korea Midwest, The collection and cultivation of medici nal scope was broader, because difference of fatty acid content by natural habitat was light.

The effect of sudden changes of water temperature (WT) on the survival rate and physiological responses of the red spotted grouper (Epinephelus akaara) were examined by manipulating WT control system for 9 days. Experimental condition was divided in two different regimes at low (from 10°C to 4°C, decreased 1℃/d) and high (from 28°C to 34°C, increased 1°C/d) WT. Survival rate of experimental fishes were observed, and determined the changes of hematological characteristics by analyzing plasma levels of cortisol, glucose, total protein, and electrolytes (Na+, Cl–, K+). No mortality was observed until low WT 6°C (144 h) and high WT 32°C (96 h), and 100% mortality was observed at low WT 4°C (216 h) and high WT 35°C (171 h). Plasma levels of cortisol and glucose increased rapidly as decreasing WT, and the loss of swimming ability and respiration response was observed at low WT 7°C and high WT 34°C conditions.

Safflower (Carthamus tinctorius L.) seeds have long been clinically used in Korea to promote bone formation and prevent osteoporosis. In addition, the safflower buds (SB) were found to have more useful functional ingredients than safflower seed. Thus, we investigated the preventive effects of SB diet in ovariectomized (OVX) rats. The rats were divided into five groups; sham operated group, OVX alone group, OVX plus 17β-estradiol (E2 10 ㎍/㎏, i.p.) and OVX plus SB diet feeding group (0.3% or 1%). Feeding of SB diet (0.3% or 3%) to OVX rats markedly increased trabecular formation in femur compared to OVX rats. Feeding of SB diet (0.3% or 3%) to OVX rats also decreased TRAP activity compared to OVX rats. These results suggest that SB diets have bone sparing effects by the decrease of osteoclast activity. We also observed that OVX rats fed with SB diet (0.3% or 3%) exhibited the decrease of calcium and phosphorus in serum compared to OVX-induced rats. Therefore, SB may be beneficial for the patients of osteoporosis, especially in postmenopausal women.

UDP-glucose 4-epimerase (UGE; EC 5.1.3.2) is an enzyme that plays an essential role in the interconverts UDP-D-glucose (UDP-Glc) and UDP-Dgalactose (UDP-Gal). Five members of the Chinese cabbage (Brassica rapa) UDP-glucose 4-epimerase gene family, designated BrUGE1 to BrUGE5, have been cloned and characterized. Quantitative PCR shows that the BrUGE1and BrUGE4 mRNA are most abundant among other BrUGE genes, accounting for more than 55% of total BrUGE transcripts in most of the tissues examined. All genes showed organ specific expression pattern, two of which (BrUGE1 and 4) actively responded after Pectobacterium carotovorum subsp. carotovorum infection, while four genes (BrUGE-1, -3, -4 and -5)were shown to respond considerably against salt, drought and abscisic acid (ABA) treatments. To better understand the function of the UGE gene, we constructed a recombinant pART vector carrying the BrUGE1 gene under the control of the CaMV 35S promoter and nos terminator and transformed using Agrobacterium tumefaciens. We then investigated BrUGE1 overexpressing rice lines at the physiological and molecular levels under biotic and abiotic stress conditions. Bioassay of T3 progeny lines of the transgenic plants in Yoshida solution containing 120 mM Nacl for 2 weeks, confirmed that the BrUGE1 enhances salt tolerance to transgenic rice plants. Also T3 progeny lines of the transgenic plants, when exposed to infection caused by Xanthomonas oryzae pv oryzae, showed tolerance to bacterial blight. These results showed that BrUGE1 can be used as potential genetic resource for engineering Brassica with multiple stress resistance.
