The purpose of this study was to understand better the difference of biochemical contents between the conserve Korean wild tea trees and introduced tea cultivars that have been cultivated in the same field. The Korean wild tea germplasms were collected from Jeonnam province in 1998. The preparation method for the high performance liquid chromatography(HPLC) analysis of the biochemical contents of tea trees was modified to rapid and labor-saving one. The caffeine and catechin contents extracted from the powdered tea leaves using the liquid nitrogen were higher than the finely chopped and the cut tea leaves. And the optimum extraction time was 30 min. The tea leaves incubated at -5˚C (2 hr) had higher caffeine and catechin contents than the fresh leaves. Likewise, caffeine content fo new leaves was significantly higher than old leaves. The Korean wild tea accessions showed high caffeine, EGC, and ECGC contents compared to the introduced tea cultivars. Specifically, the content of caffeine in Wolchul 3-13 was six times higher than the Japanese tea cultival "Saemidori".

국내산 재래종 및 가공녹차를 이용한 미생물발효차의 개발 가능성 및 발효과정중의 특성 변화를 검토하고자 국내산 재래종 및 가공녹차, 야부키타종, 그리고 대차종을 이용한 미생물발효차를 제조하고 발효과정 중 품질 특성을 조사하였다. 모든 원료에서의 미생물발효차의 발효특성은 발효가 진행될수록 적색도 및 황색도가 증가하였고, 클로로필과 탄닌 함량은 감소하였다. 총 질소 및 카페인의 함량은 발효가 진행됨에 따라 큰 변화를 보이지 않았으나 총 catechin 및 개별 카테킨류 중 catechin, ECG, EGCG의 함량은 꾸준히 감소하였다. 그리고 EC와 EGC의 함량은 25일까지 증가하다가 그 이후 감소하였다. 대차종 및 야부키타종의 경우 발효가 진행됨에 따라 항산화활성이 감소한 반면, 국내산 재래종 및 가공녹차는 그 활성을 그대로 유지하였다. 국내산 재래종 및 가공녹차는 발효가 진행됨에 따라 대차종 및 야부키타종과 유사한 발효 양상을 나타냈으나 수색이나 카테킨 및 카페인 등의 성분 함량은 다소 차이를 보였다. 본 연구로부터 국내산 재래종 품종의 찻잎 및 이를 이용하여 제조된 녹차의 미생물발효차 제조가능성을 확인할 수 있었다. Microbial-fermented tea (MFT), which is made by microorganisms through fermentation, is a popular beverage in Asia, especially in the Yunnam province, China. In this study, changes of the chemical constituents and antioxidant activity during the manufacturing process of MFT were investigated. MFT were respectively prepared from fresh leaves of three different tea species (Yabukita, Daecha, and Korean wild cultivar) and a processed green tea (Korean wild cultivar). The color of the tea infusions gradually changed to red and yellow as a function of fermentation time. Total nitrogen and caffeine contents were not significantly changed. Whereas, the chlorophyll, tannin, and total catechins contents gradually decreased. Interestingly, the epicatechin and epigallocatechin contents increased up to 25 days of fermentation and then decreased. Change of the chemical constituents of all samples showed the same patterns. The antioxidant activity of MFT from Daecha and Yabukita slightly decreased as increasing fermentation time. However, the range over which the antioxidant activity of MFT from Korean wild cultivar and green tea were not changed. This research suggests that it may be possible to manufacturing possibility of MFT using Korean wild cultivar and processed green tea.

재배기간에 따른 고구마 전분의 특성을 구명하여 고구마의 새로운 식품산업 소재로서 활용방안을 모색하기 위한 기초자료로 이용하고자 실험한 결과는 다음과 같다. 재배기간이 길어질수록 전분 함량은 증가하였으나 아밀로스 함량은 감소하는 경향이었고, 일반고구마와 유색고구마의 전분함량 변화 양상에는 차이가 있었다. 재배기간이 길어질수록 전분의 수분함량 변화 양상은 일정한 경향을 보이지 않았으나 단백질과 회분 함량은 증가하는 경향이었다. 신속점도측정기로 측정한 점도는 재배기간이 길어질수록 전분의 호화개시온도와 최고점도, breakdown, setback은 증가하였고 최소 및 최종점도는 감소하였다. 주사시차열량계를 이용한 호화특성은 재배기간이 길어질수록 To, Tp는 증가하였으나 Tc, ΔT, ΔH는 일정한 변화 양상을 보이지 않았다. X-선 굴절률은 일반고구마의 회절각도는 15.08-15.32°, 16.92-17.72°, 22.90-23.62°, ‘신자미’ 15.26-15.34°, 17.08-17.32°, 22.74-23.40°, ‘주황미’ 14.98-15.32°, 17.00-17.38°, 22.82-23.40°에서 강한 피크를 보여 전분의 결정화도 형태 중 C형에 속하였으며 재배기간에 상관없이 고구마 전분의 결정화도는 일정하였다. 고구마 전분의 입자 형태는 재배기간에 상관없이 대부분 둥글고 타원형 모양을 하고 있었으며 일부 다각형의 입자 형태를 포함하고 있었다. 평균입도는 주황색고구마의 평균입도가 식용 및 자색고구마보다 컸으며 재배기간이 길어질수록 고구마 전분의 평균입도는 증가하였다. This study was performed to understand the effect of cultivation periods on the physicochemical characteristics of the starch of five sweetpotato cultivars, cultivated in Muan, Korea. Starch, protein, and ash contents increased with increased cultivation period, whereas amylose content decreased. Rapid viscosity analysis showed that the pasting temperature, peak viscosity, breakdown, setback and final viscosity increased with increased cultivation period. However, trough and final viscosity decreased. Although the onset temperature and peak temperature values increased, the conclusion temperature did not show any consistent patterns by differential scanning calorimetry. X-ray diffraction showed that the starch samples had C-type crystallinity irrespective of the cultivation period and cultivar. The starch granules were dominantly round and oval, or polygonal irrespective the cultivation period. The bigger the particle size was, the longer the cultivation period was.

Objective: This study examined the differences in the complications developed by mothers and newborns before and after childbirth according to the placental attachment site in patients with placenta previa. This will provide information to help prepare countermeasures to reduce complications in mothers with placenta previa in the future. Methods: For this retrospective cohort study, we examined the medical records of 383 pregnant women who delivered with a diagnosis of placenta previa at our Obstetrics and Gynecology Department from January 2013 to June 2022. Patients were into two groups: anterior placenta previa and posterior placenta previa groups. The basic characteristics of the pregnant women, including age at childbirth, gestational period, and weight during prepregnancy; and the occurrence of maternal complications, such as need for blood transfusion according to the location of placenta and amount of bleeding during surgery, were investigated. In addition, the correlation between history of uterine surgery or cesarean section and the placental position was statistically verified and derived according to the number of uterine surgeries. Results: Mothers in the anterior placenta previa group had higher rates of transfusion, bleeding, and uterine artery embolization during hospitalization (p-value<0.05). The prevalence of placental adhesion was higher in the anterior placenta previa group (p-value<0.05). Conversely, assisted reproductive surgery, history of uterine surgery, and frequency of previous uterine surgery did not affect the location of the placenta. Conclusion: The possibility of intraoperative bleeding during surgery increases in cases of anterior placenta previa, because the placenta is incised during surgery. The frequency of placental adhesions is also considered to be high. Therefore, to prevent and reduce the various risks that occur during childbirth, it is important to identify the exact location of the placenta and to prepare for bleeding before and after surgery. As such, it is necessary to take measures such as insertion of a uterine artery catheter before delivery, use ultrasound during surgery to determine the exact boundary of the placenta to perform appropriate incision, or aggressive uterine artery embolization after delivery.

Perilla species belong to the Lamiaceae family of flowering plants and are widely grown in East Asia, for use in a traditional herbal medicine or functional food. To identify single nucleotide polymorphisms (SNPs) in Perilla species and conduct a phylogenomic analysis, we determined the complete sequences of the chloroplast (cp) genome and 45S nuclear ribosomal DNA (45S nrDNA) of six cultivated and three wild Perilla species. The complete cp genome ranged in size from 152,588 bp to 152,656 bp and the length variation in cp genomes was 68 bp. The length of the 45S nrDNA ranged from 6,235 bp to 8,303 bp and the main variation of length differences was in the intergenic spacer (IGS) region. Comparative analysis of the cp genome sequences of nine Perilla species showed low genetic diversity at the intra- and inter-species level. Using SNP analysis, we detected 42 synonymous SNPs (sySNPs) from 27 genes and 37 non-synonymous SNPs (nsSNPs) from 15 genes. A comparison of the 45S nrDNA sequences revealed two SNPs in the 18S rRNA, five SNPs in the 26S rRNA, three SNPs and two InDels in the internal transcribed spacer (ITS) 1 region, and six SNPs in the ITS 2 region. Our phylogenomic analysis suggests that the tetraploidization of Perilla cultivars may have arisen from the P. citriodora genome. The genotyping data from this study may be used to develop molecular markers associated with useful traits for use in Perilla breeding.

Background: The angiotensin-converting enzyme (ACE) has a major role in the degradation of bradykinin, tachykinin, substance P which are associated with bronchial hyperresponsiveness and inflammation. The other role of ACE is the genesis of angiotensin II which causes bronchial smooth muscle contraction. The deletion polymorphism of ACE gene(DDtype) may be related to the high serum level of ACE. Objective: We studied to evaluate an association between the insertion /deletion polymorphism of the ACE gene and asthma, and its severity. Materials and methods: Sixty asthmatic patients and 44 healthy controls were enrolled. Severity of asthma was classified by the guideline of NHLBI/WHO workshop. The ACE genotypes of all the subjects were determined by polymerase chain reaction. Results: The distribution of ACE genotypes were not significantly different between healthy controls and asthma group (p)0.05). In asthmatic patients, the genetic polymorphism was similar between different severity groups (p) 0.05). Conchcsion: It is suggested that I/D polymorphism of the ACE gene may not be associated with development of asthma. The severity of asthma may not be influenced by I/D polymorphism of the ACE gene.
