This study was carried out to identify the effects of seaweed extracts(GA14) on growth of two rice cultivars, Junambyo and Donganbyo. Seedling qualities of two cultivars were better in all items including heading dates at early stage treated at seedling plus 2-3 leaf stages than at single treatment of seedling. Ripening ratio of Junambyo in paddy field was increased 0.3% by seaweed extracts(GA14) treatment, but that of Donganbyo decreased 0.5%. 1,000 grain weight of Junambyo and Donanbyo by seaweed extracts(GA14) treatment was two to four grams higher and the yield of two cultivars was also higher by three to four percent. Appearance characters of two rice cultivars was high in head, while damaged, chalky and crack rate were low at seaweed extracts(GA14) treatment. Protein, moisture and amylose characteristics related to table quality of Junambyo were not different by seaweed extracts treatment, but table values was high in only treatment. Donganbyo was also similar to Junambyo, but table quality was slightly high at non-treatment.

Objectives: Although there have been several reports that described characteristics for young age stroke, information regarding very young age (18–30 years old) has been limited. We aimed to analyze demographic factors, stroke subtype, and 3-month outcome in acute ischemic stroke patient who have relatively very young age in multicenter stroke registry. Methods: We evaluated all 122 (7.1%) consecutive acute ischemic stroke (within 7 days after symptom onset) patients aged 18 to 30 from 17,144 patients who registered in multicenter prospective stroke registry, 1997 to 2012. Etiology was classified by Trial of Org 10172 in Acute Stroke Treatment criteria. Stroke severity was defined as National Institutes of Health Stroke Scale (NIHSS) and stroke outcome was defined by modified Rankin scale (mRS) at 3 months after index stroke. Results: The mean age of all included patients was 25.1±3.7 years and 76 patients (62.2%) were male. The median NIHSS at admission was 4. Considering stroke subtype, 37 patients (30.3%) had stroke of other determined etiology (SOD), 37 (30.3%) had undetermined negative evaluation (UN) and 31 (25.4%) had cardioembolism (CE) were frequently noted. After adjusting age, sex and variables which had P<0.1 in univariable analysis (NIHSS and stroke subtype), CE stroke subtype (odds ratio, 4.68; 95% confidence interval, 1.42–15.48; P=0.011) were significantly associated with poor functional outcome (mRS≥3). Conclusion: In very young age ischemic stroke patients, SOD and UN stroke subtype were most common and CE stroke subtype was independently associated with poor discharge outcome.

N/A Objectives: Mutations in the glucokinase (GCK) gene are considered a possible cause of maturity-onset diabetes of the young. The purpose of this study was to evaluate the contribution of this gene to the development of non insulin dependent diabetes mellitus (NIDDM), gestational diabetes mellitus (GDM) and post-renal transplantation diabetes mellitus (PTDM). Method: Identification of GCK mutation was attempted on 39 NIDDM patients, 2 GDM patients and 58 selected renal allograft recipients with PTDM and 45 normal controls. The exons in the GCK gene were examined by polymerase chain reaction (PCR), followed by analysis of single-stranded DNA conformational polymorphism (SSCP). The abnormal bands were also confirmed by DNA sequencing analysis. The exons of affected family members were also investigated for mutations of the GCK gene. Results: Two of the 58 PTDM patients (3.4%) were found to have CKK mutations. One had the mutation on exon 5 and the other on intron 7. One control subject had the mutation on intmn 9. The mutation of exon 5 was identified as a substitution of CCT (proline) for CTT (leucine) at codon 164, which has not ever reported before. The family members of the PFDM patient with mutation of exon 5 were analyzed by PCR followed by SSCP, and two of them revealed the same mutation. The abnormal band on the SSCP analysis of exon 7 was identified as the insertion of base C/T at the 39th nucleotide in intron 7. Two family members of this patients also had same band on SSCP. The one mutation of 45 normal controls was CT located at the 8th nucleotide in intron 9, which was a common polymorphism. Conclusion: We found GCK mutations in subjects with PTDM and we speculate that these mutations may be one of the contributing cause of PTDM.

Objectives : We examined the effects of INM 176 (K-l107) compared with placebo on the cognitive functions of 92 old aged subjects with cognitive impairment. Methods : This was a prospective, 12 week, double-blind, Placebo-controlled clinical trial. The elderly who achieved a score of less than 25 points on the K-MMSE or showed a high risk of Alzheimer's disease from the 7-Minute Neurocognitive Screening Battery were considered to have objective impairment and were selected as subjects for this study. The subjects were randomized to placebo or INM 176 group. The outcome measures were from the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-Cog), the Instrumental Activities ofDaily Living (IADL) and the Korean Geriatric Depression Scale (KGDS) and two kinds of computerized priming tests. After setting the total error score in the Alzheimer's Disease Assessment Scale-Cognitive section (ADAS-cog) as the repeated measurement factor, an analysis of variance of the combined factor design was done between the placebo and INM 176 group. Results : The interaction effect of time (pre- and post-trial) and group (placebo and INM 176 group) was significant in the analysis of the ADAS-cog's total error score. The INM 176 group's total error score in the ADAS-cog decreased significantly (p<0.01), whereas the placebo group showed a slight increase. The mean changes in IADL and GDS from baseline scores favored in the INM 176 group than in the placebo group. Outcome changes ofADAS-cog, IADL, KGDS scores during the 12 week clinical trail ofINM 176 and placebo demonstrated favorable responses in the INM176 administered group. Conclusions : This is a preliminary clinical trial result of INM176 as a memory pill. Based on these results, INM176 may be a candidate molecule for the improvement of cognitive functions, including memory, Further clinical trial should demonstrate its efficacy.

Background/Aims: Inflammatory diseasas of the pancreas are not uncommon. The advanced age is one of the significant factors in assessing the severity of acute pancreatitis. It has been shown that the biliary tract disease is a more frequent cause of acute pancreatitis in the elderly than in the young. With the increased life span, the elderly are comprising a large proportion of the population. As a result, physicians are more often being faced with acute pancreatitis in the elderly. The purpose af this study was to evaluate clinical features of acute panereatitis in the elderly. Methods: A total of 188 patients with acute pancreatitis were reviewed. We investigated the differences of clinical characteristics between the elderly patients aged over 60 and the young patients aged under 60. Results: The sex distribution showed male preponderance in the young patients (M:F=2.4:1), but was nearly equal in the elderly patients (M:F=1.1:1). The most common cause of acute pancreatitis in the elderly was biliary tract disease (52.5%), while alcohol abuse was the most common cause in the young patients (38.8%), Local complications of acute pancreatitis, such as psuedocyst, necrosis, abscesses were not differently shown between the elderly (16.9%) and the young (20.2%) patients. Systemic complications including acute puhnonary failure occurred more frequently in the elderly patients than the young patients. The mortality rate of the elderly patients (5.1%) was not significantly different from that of the young patients (3.1%). Conclusions: To detect correctable underlying bihary tract diseases the elderly patients with acute pancreatitis should be completely investigated using endoscopic retrograde cholangiopancreatography (ERCP). In addition, the patient should be closely monitored for the development of the systemic complications during the disease process.

I have tried to find out the phenomena and the reason of the weakness and deletion of the English weak vowels by reviewing the studies and researchs of the English linguists. The English vowels can be weakened and deleted when they come just in front of or just after the weak syllable, when they come at the end of the word which lost its importance through its historical process, when they get pressure by two strong syllables, when several weak vowels come consecutively and when they get affection by the vowel environment.

심부 매복 정중 과잉치 수술 시 마취방법 선택

Supernumerary tooth occurs most frequently at premaxilla area. Followed by mandibular premolar area, mandibular fourth molar area, maxillary paramolar area. Mesiodens are mainly impacted in the palatal area and surgical approach is made at palatal side. The time of surgery remains controversial. In case of inverted or horizontal impacted supernumerary tooth, intraosseous tooth movement and vertical growth of premaxilla makes surgical extraction more difficult. And also the more quantity of removed bone is, the higher degree of difficulty is. Inverted mesiodens of these cases were impacted superior to apex level of adjacent permanent incisor. Although CT examination revealed exact location of impacted tooth, surgical procedure including ostectomy may take a long time more than expected. So, before surgical extraction, it’s need to be considered several factors such as necessity of CT taking, degree of difficulty, direction of surgical approach, necessity of general anesthesia etc. 정중 과잉치(mesiodens)는 대개 상악 절치부에서 발견되며, 주로 구개측에 위치하는 경향이 있다. 정중 과잉치의 자연맹 출 가능성이 관찰되면, 주기적으로 검사하여 구강내로 충분히 맹출한 후에 단순발치를 시행한다. 주기적 검사에서 자연맹출 소견이 보이지 않거나, 형태이상 혹은 맹출방향의 이상으로 구강 내로 자연맹출 할 가능성이 없으면, 수술적 제거방법을 고려 해야 할 것이다. 특히, 인접한 중절치나 측절치의 맹출을 방해하고 있는 상황이 관찰된다면, 빠른 시일 내에 과잉치 제거를 위 한 수술적 방법을 시도하는 것이 타당하다. 한편, 외과적 수술의 시기를 늦추는 것을 고려해야 하는 경우도 있다. 정중과잉치가 인접하여 발육중인 정상 치아의 맹출을 방해하지 않는 경우이다. 이때, 삼차원 CT사진을 촬영하여보면, 과잉치 주변으로 영구절치의 치배가 근접하여 성곽처럼 둘러 싸고 있는 것을 볼 수 있다. 미성숙한 치배가 둘러 싸고 있는 상황에서, 무리하게 과잉치를 제거하려고 시도할 경우 인접 치배 를 손상시킬 가능성을 배제하기 어렵다. 이 점을 고려 한다면, 가급적 인접한 치아의 치근이 보다 발육한 후에 수술을 시도하 는 것이 바람직할 것이다. 초등학교 2학년 이상의 어린이들은 외래에서 국소마취하 제거하는 수술방법에 대개 잘 적응하며 고학년이 될수록 보다 수월해진다. 수술시기를 너무 늦추거나, 과잉치가 너무 늦게 발견된 경우 구개측 심부로 깊이 이동한 것을 볼 수 있다. 때로는 과잉치의 위치가 처음부터 심부에 매복되어 있을 수 있다. 이와 같은 경우, 전신마취방법을 생각해 볼 수 있을 것이다. 본 증례는 상악 정중부의 깊은 부위에 역위 매복된 과잉치를 외래에서 국소마취하에 치료를 시도할 때 관찰되는 문제점을 고찰하였고, 전신마취방법을 결정하기 위한 기준을 제시하였다. 심부 매복된 치아의 외과적 발거시 어린이의 행동조절이 가장 큰 문제였으며, 방사선 소견상 과잉치 치관의 위치가 절치의 치근단보다 상방에 위치할 경우 전신마취로 전환 하는 것이 바람직 할 것으로 사료된다.
