Background: Maintaining optimal blood inventory levels in hospitals is important to prevent blood shortage and wastage. We aimed to provide an efficient blood inventory management strategy for hospital blood banks nation-wide by comparing the current use of 5-day issuable stock (IS) with Lim’s IS as a novel target IS. Methods: The average and CV of daily usage (DU) were calculated from information entered into Korea’s Blood Management System by 194 participating hospitals in 2019 and 2020. Using these data, Lim’s IS was calculated by determining the simulated annual average blood shortage day nearest to 1 for each blood group in each hospital. The 5-day IS (5IS) was estimated by multiplying the average DU in 2018 by five to count the shortage days in 2019. Results: The average DU (0.3–231.3 units) and corresponding CV (0.33–7.14) in the participating hospitals were inversely proportional (r=–0.699 to –0.695). The hypothetical averages of 5IS and Lim’s IS were 27.0±41.2 and 24.7±20.8, respectively (P=0.006). The shortage days for 5IS and Lim’s IS were 8.9±22.7 and 1.0±1.9, respectively (P<0.001). Conclusions: While 5IS was unacceptable for universal application, Lim’s IS remained near one shortage day and is considered more efficient than 5IS. Hospitals should implement indicators that consider DU and its variations. This is the first study to introduce Lim’s IS as an indicator of optimal blood inventory, and the data are expected to provide guidance for effective blood inventory management nationwide, particularly during blood shortages.

To make rice cake with squid ink, the squid ink dilulted in fifteen times was added to rice flour in the ratio of 0%, 2%, 4%, 6% and 8% respectively. Then, the squid inky rice cake was tested in physical function and chromaticity, Rheometer test was also included in this experiment. In physical function test, it showed that the inky rice cake with 6% and 8% ratio was the best in preference. In the chromaticity test, as the adding ratio of squid ink increases, the brightness decreased. The red and yellow brightness of 8% inky rice cake showed high. The results of rheometer test are as follows. In hardness, the inky rice cake with 2% adding ratio was high and the 6% inky rice cake was low. In cohesiveness, the 0% inky rice cake was high and the 8% inky rice cake was low. In gumminess, the 2% inky rice cake was high and the 6% inky rice cake was low. In brittleness, the 2% inky rice cake was high and the 6% inky rice cake was low. With correlation analysis, I could reach the following. The overall quality of inky rice cake was correlated with all test items except chewiness, The moistness was correlated with flavor, grain and chewiness. Also, the 8% inky rice cake was correlated with the inky rice cakes with the other adding ratios in all aspects of test. Futhermore, in the results of rheometer test, the hardness was correlated with the other three kinds of characteristics.

본 연구는 교정환자의 브라켓과 치아 경계부 및 브라켓으로부터 2 mm 이상 떨어진 치아 평활면의 치면세근막에 존재하는 mutaus streptococci의 종 및 생물형에 차이가 있는지를 알아보고자 시행되었다. 조선대학교 치과병원에 내원한 13세 이상 35세 미만의 환자 28명으로부터 브라켓을 장착하고 있는 61개 치아에서 치균세균막을 채취하여 mutans streptococci를 MSB 배지에서 선택적으로 분리한 다음, 이들의 지놈 DNA를 추출하여 dextranase 유전자를 표적으로 하는 중합효소연쇄반응법을 시행하고, 그 증폭물을 Hae Ⅲ로 소화하고, 이를 전기영동하여 제한효소절편길이에 따라 그 종을 식별하였다. 또한 생물형을 조사하기 위하여 생화학적 검사를 실시하였다. 그 결과 브라켓과 치아 경계부 및 브라켓으로부터 2 mm 이상 떨어진 평활면의 치면세균막에 존재하는 mutans streptococci 종은 서로 비슷한 검출 빈도를 보이나 두 곳에 존재하는 mutans streptococci 생물형은 서로 차이가 있는 것으로 나타났다. 향후 브라켓과 치아 경계부 및 치아 평활면의 치면세균막의 mutans streptococci 생물형의 차이와 브라켓 주위의 법랑질 탈회 및 치아우식증 발병과의 상관관계에 대한 연구가 필요하다. The aim of this study was to compare the species and biotypes of mutans streptococci isolated from dental plaques sampled from the interfaces between the bracket and tooth surface and smooth tooth surfaces in orthodontic patients. Dental plaque was collected from the interfaces between brackets and teeth (test group), and from smooth tooth surfaces distant from brackets by more than 2 mm (control group). The dental plaque collected by a sterilized curette was transferred into a vial of 1 X PBS. The sample in the vial was vigorously vortexed for1 min and plated on mitissalivarius bacitracin (MSB) agar plate using cotton tips. The agar plates were incubated at 37℃ in a candle jar for 2 days, and again incubated for 1 more day at anambient temperature. Individual colonies were cultured in TH broth at 37℃ CO₂ incubator. The PCR-RFLP based on dextranase gene was performed for the identification of mutans streptococci at the species-level. For biotyping of mutans streptococci, biochemical tests were performed. There was no significant difference of the species of mutans streptococci isolated from both test and control groups. However, the biotypes of the mutans streptococci isolated from test and control groups were different. These results may offer the basic data to verify the relationship between the mutans streptococci biotype and enamel decalcification or dental caries in orthodontic patients with fixed appliances.

Oddi is a mulberry (Morus alba L) fruit which has antiinflammatory and antioxidative effects. This study was carried out to investigate the quality characteristics of Oddi-Pyun which was manufactured with various addition levels (0, 0.5, 1, 2, 4%) of Oddi extract according to the traditional Korean Kwaypun (a kind of jelly) methodology. Oddi-Pyun was made with various levels of Oddi extract, mungbean starch (9%) and sugar (30%). To establish the additional amount of mulberry fruit extract, sensory evaluation and physical test were carried out. From the results of sensory evaluation, the 2% of Oddi-Pyun was judged as the best in terms of color, flavor, hardness and elasticity. According to texture characteristics (hardness, adhesiveness, springiness, gumminess and chewiness), 1.0% and 2.0% of Oddi-Pyun were judged as the best. The contents of Ca (69.50, 74.75, 84.25, 100.60, 183.55ppm), Mg(27.37, 29.38, 34.20, 46.73, 97.45ppm) and Fe (320.23, 572.45, 680.50, 725.95, 906.50ppb) increased with increasing Oddi extract. Therefore, the optimal added amount of extract for the manufacture of Oddi-Pyun was proposed as 2% to the total weight. It was concluded that this Oddi-Pyun would be helpful to improve the health status of rheumatics and patients with similar diseases.

Phytocystatins are protein inhibitors of cysteine proteinases of the papain family that have been identified in both monocot and dicot plants. A cDNA encoding a phytocystatin, BCPI-1 (Brassica Cysteine Proteinase Inhibitor-1) has been isolated from Chinese cabbage (Brassica campestris L. ssp. pekinensis) flower buds. Here, we tested whether BCPI-1 transcription is regulated by hormones, and could be involved in regulating cysteine proteinases during and after germination. BCPI-1 was sensitive to exogenous GA_(3) and ABA, which are important factors controlling seed germination, suggesting that the expression of BCPI-1 is hormonally regulated. We introduced a recombinant plasmid containing the full-length BCPI-1 cDNA under the control of cauliflower mosaic virus 35S promoter into rice embryogenic calli using the particle delivery method, and regenerated a number of transgenic rice plants. Constitutively over-expressed BCPI-1 caused changes in overall plant growth and development, including reduced germination and seedling growth. These data support the role of the BCPI-1 in the regulation of endogenous proteinases during both seed germination and subsequent seedling development. Phylocystatins은 papain계열의 cysteine 단백질 분해 효소 활성을 특이적으로 억제하는 억제자로 다양한 식물 종으로부터 분리되었다. 본고에서는, 배추 화아 cDNA library로부터 분리된 phytocystatin인 BCPI-1(Brassica Cysteine Proteinase Inhibitor-1)의 생체 내 기능에 대해 연구하였다. 먼저, BCPI-1 전사체는 발아 조절에 중요한 영향을 미치는 GA₃와 ABA에 의해 예민하게 증가, 혹은 감소되는 반응을 보임으로써, BCPI-1이 식물 호르몬의 영향을 받으며, 특히 발아나 유묘의 생장 조절에 관련이 있음을 알 수 있었다. Particle bombardment 방법을 통하여 BCPI-1을 벼의 배 형성 세포 내에 도입, 재분화 시켜 형질 전환 벼를 생성하였다. CaMV 35S promoter의 조절에 의해 지속적인 BCPI-1 발현을 보이는 형질 전환 벼의 경우, 발아와 유묘 생장이 현저히 지연되었다. 위의 결과들을 바탕으로, BCPI-1이 식물체 내에서 생성되는 cysteine 계열의 단밸질 분해 효소 활성을 조절하여 종자의 발아와 유묘의 생장에 영향을 미치는 것으로 추측한다.
