As hyaluronic acid filler commonly applied in many cosmetic fields, tissue necrosis due to filler embolism is reported infrequently. Herein we report the first case of nasal hyaluronic acid filler injection resulting in nasal necrosis, multifocal brain infarction and ocular ischemia with hypotonia. A 25-year-old female, who had received an injection of hyaluronic acid filler along the nasal dorsum a month before, visited our hospital to manage the skin ulcer of nasal ala. Immediately after the injection, the patient had complained of nausea,vomiting, headache and nose pain without neurologic symptom. The skin had bluish change at her nose and forehead. And the right eyelid ptosis was observed with decreased eyeball movement and visual loss. Multifocal punctuated infarctions were found on both frontal lobes on brain MRI. The necrotic skin of right nasal ala was healed in 3 months. But, the width of the right nasal ala was smaller than the left side, and the right eye remained blind with extropia at 8 months after injection. Although hyaluronic acid filler is safe in most cases, patients should be informed of the possibility of this rare complication.

The Effects of Aging and Mild Cognitive Impairment on the Tip-of-the-Tongue Phenomenon in People Naming Task

오상아,하지완 대한치매학회 2015 Dementia and Neurocognitive Disorders Vol.14 No.1

Background and PurposeThe tip-of-the-tongue (TOT) phenomenon refers to knowing the meaning of the desired information but being unable to produce the phonological information. This study induced the TOT phenomenon through a task involving naming famous people, compared and analyzed results by age, and examined the differences with effects from pathological aging [mild cognitive impairment (MCI)]. MethodsYoung (n=10), middle-aged (n=10), older (n=10), oldest (n=10), and MCI (n=10) subjects participated in this study. To examine TOT rate, rate of TOT response, voluntary TOT solution rate, and TOT solution rate after presenting syllabic cue, each group participated in the experiment through a task of naming famous people. ResultsFirst, as subject age increased, TOT rate (the number of TOTs divided by total trials) increased. There was no significant difference with pathological aging. Second, normal aging and pathological aging had no significant effect on the rate of TOT response (the number of each response type divided by total response types). Third, the voluntary TOT solution rate (the number of voluntary TOT solutions divided by total TOTs) on occurrence of the TOT phenomenon was very low. Fourth, the TOT solution rate (the number of TOT solutions after presenting syllabic cue divided by total TOTs) had a negative correlation to normal aging. In examining pathological aging, the TOT solution rate of the MCI group was significantly lower than normal oldest people. ConclusionsNormal aging and pathological aging showed differences regarding TOT rate and TOT solution rate when naming famous individuals. The results of this study could be helpful as a differential tool between normal and pathological aging.

The RpoS Sigma Factor Negatively Regulates Production of IAA and Siderophore in a Biocontrol Rhizobacterium, Pseudomonas chlororaphis O6

오상아,김영철,김지수,박주연,한송희,Christian Dimkpa,Anne J. Anderson 한국식물병리학회 2013 Plant Pathology Journal Vol.29 No.3

The stationary-phase sigma factor, RpoS, influences the expression of factors important in survival of Pseudomonas chlororaphis O6 in the rhizosphere. A partial proteomic profile of a rpoS mutant in P. chlororaphis O6was conducted to identify proteins under RpoS regulation. Five of 14 differentially regulated proteins had unknown roles. Changes in levels of proteins in P. chlororaphis O6 rpoS mutant were associated with iron metabolism, and protection against oxidative stress. The P. chlororaphis O6 rpoS mutant showed increased production of a pyoverdine-like siderophore, indole acetic acid, and altered isozyme patterns for peroxidase, catalase and superoxide dismutase. Consequently, sensitivity to hydrogen peroxide exposure increased in the P. chlororaphis O6 rpoS mutant, compared with the wild type. Taken together, RpoS exerted regulatory control over factors important for the habitat of P. chlororaphis O6in soil and on root surfaces. The properties of several of the proteins in the RpoS regulon are currently unknown.

Purpose: There is a fair amount of evidence indicating that increased risk of obesity and insulin resistance is associated with postmenopausal state, but can be modulated by diet and exercise. In this study, we explored whether a Pueraria lobata root-based supplement containing Rehmannia glutinosa (PR) and/or aerobic treadmill exercise can modify the metabolic changes associated with estrogen deficiency. Methods: Seventy rats were randomly assigned to the following groups for 8 weeks (n=10 per group): SHAM, sham-operated; PR0, ovariectomized (OVX) control; PR200, OVX with PR200 mg/kg B.W; PR400, OVX with PR400 mg/kg B.W; EPR0, OVX with exercise; EPR200, OVX with exercise and PR200 mg/kg B.W; EPR400, OVX with exercise and PR400 mg/kg B.W. Results: OVX induced significant increases in body weight, food intake, fat mass, LDL-cholesterol, and fasting blood glucose, confirming induction of menopausal symptoms. PR supplementation or exercise significantly suppressed the above mentioned changes through different regulatory elements in adipose tissue: PR supplement upregulated adiponectin gene expression and aerobic exercise upregulated adiponectin and insulin receptor gene expression and a combination of PR supplement and aerobic exercise showed an additive effect on adiponectin gene expression. Conclusion: Taken together, the results of this study suggest that PR supplement has a potential to provide health benefits in OVX rats through leptin and adiponectin secretion. In addition, the data suggest that combination of exercise and PR would have additive effects on metabolic dysfunction associated with estrogen deficiency. v본 연구는 갈근과 지황 복합물과 유산소 운동이 난소절제로 갱년기를 유도한 흰 쥐에서 나타나는 지질 및 당대사이상에 미치는 영향을 확인하였다. 난소절제 후 8주간AIN-76A 식이를 급여한 결과 체중증가량, 식이섭취량, 체지방, 혈장 LDL-C, 공복혈당 증가를 통해 갱년기 동물 모델이 유도되었음을 확인할 수 있었다. 갈근과 지황 복합물과 유산소 운동은 서로 다른 기전으로 에스트로겐 분비 저하로 나타나는 비만 및 대사이상을 정상화하는 유익한 결과를 나타냈다. 지방 조직에서 확인된 관련 기전으로는 갈근과 지황 복합물로 인한 아디포넥틴 유전자 발현 증가 및렙틴저항 억제, 유산소 운동으로 인한 아디포넥틴 및 인슐린 수용체 유전자 발현 증가, 갈근과 지황 복합물 및 유산소 운동의 병행으로 인한 아디포넥틴 유전자 발현 증가 상승효과가 관찰되었다. 이상의 결과로 갈근과 지황 복합물과 유산소 운동의 병행은 폐경기 에스트로겐 결핍으로 인한 대사이상을 개선하는 효과가 있을 것으로 기대한다. 향후에는 폐경기 유도 동물모델의 개선과 함께 단백질 및 신호전달분자 수준에서 추가적인 기전연구가 필요할 것으로 사료된다.

To produce high quality watermelon, three tetraploid watermelon breeding lines (‘SA03-1’, ‘SA06-1’ and ‘SB01-1’) were developed by treatment with different chromosome doubling reagents. To identify the optimal tetraploid inductive conditions, the three watermelon breeding lines were selected by counting the number of doubled chloroplasts in guard cells. Tetraploid induction rates differed depending on the genotypes and treatment with doubling reagents. However, the highest induction rate occurred with 1.0% colchicine (82.2%). These putative tetraploid lines were re-confirmed for ploidy using flow cytometric analysis and chromosome counting. The internode length of the tetraploid breeding lines was different when the leaf size was larger in all three tetraploid lines compared to their diploids. The fruit weight of the tetraploid fruits for ‘SA03-1’ and ‘SB01-1’ was lower than for their diploid, and the rind thickness and total sugar content (°Brix) of tetraploid SB01-1 were significantly different from those of its diploid. Tetraploid lines were sterile, yielded a lower number of seeds per fruit for ‘SA03-1’ (21), ‘SA06-1’ (62), and ‘SB01-1’ (34.7), and the seeds were larger and thicker than those of their diploids. These tetraploid breeding results will be useful for breeding new seedless watermelon cultivars. 고품질 수박을 생산하기 위하여 서로 다른 염색체 배수화제를 처리하여 3가지 4배체 육종라인(‘SA03-1’, ‘SA06-1’ and ‘SB01-1’)을 개발하였다. 최적의 4배체 유기조건들을 조사하기위하여, 3가지 육종라인들의 4배체는 공변세포의 배수화된 엽록체 수를 조사하는 것으로 선발하였다. 4배체 유기율은 배수화제의 종류와 유전자형에 따라 다르게 나타났다. 가장 높은 4배체 유기율은 colchicine 1.0%에서 82.2%로 가장 높게 나타났다. 이들 잠재적인 4배체 라인들의 배수성은 flow cytometer와 염색체 수 분석을 이용하여 재확인하였다. 확보된 4배체 육종라인들의 절간은 그들 2배체와 비교하여 4배체와 유사하거나 짧게나타난 반면, 잎의 크기는 4배체에서 더 크게 나타났다. 과중은‘SA03-1’, ‘SB01-1’ 라인에서는 다소 감소하였고, 과피 두께와당도는 ‘SB01-1’라인에서만 2배체와 차이를 보여주었다. 4배체육종라인은 수정능력을 가지고 있었고 종자는 열매마다 ‘SA03-1’ (21개), ‘SA06-1’ (62개), ‘SB01-1’ (34.7개)로 수확되었으며, 4 배체 종자는 그들의 2배체보다 더 크고 두터웠다. 이러한 4배체품종 육성 결과는 씨없는 수박의 신품종 육성을 위해 유용하게활용될 것으로 기대된다.
