<i>Chaenorhinum minus</i> (L.) Lange of the family Plantaginaceae was discovered in Dangjin-si, Chungcheongnam-do, Republic of Korea. This species is an invasive alien plant that originated in Europe and North Africa and that was introduced into North America and East Asia. The genus <i>Chaenorhinum</i> (DC.) Rchb., to which this species belongs, is most similar to <i>Nuttallanthus</i> D. A. Sutton among related genera of the tribe Antirrhineae distributed in the Republic of Korea. While the two genera share common morphological features in the leaf and flower, <i>Chaenorhinum</i> is distinguished from <i>Nuttallanthus</i> by glandular hairs on the plant; monomorphic, fertile, and erect stems; 9.6–14.1 mm long pedicels; corolla as short as 5.6–7.9 mm; white corolla lower lips; and widely ovoid or oblong seeds. This study presents morphological descriptions and a genus key for the tribe Antirrhineae of the Republic of Korea for the identification of <i>C. minus</i> together with distribution information, voucher specimens, and photographs of this species.

개미자리속 Saginella절 식물의 새로운 미기록종 보고: 선개미자리, 민개미자리(석죽과)

이세령,박범균,이강협,손동찬 한국자원식물학회 2024 한국자원식물학회지 Vol.37 No.1

적 요최근 국내 여러 지역에서 꽃이 4수성인 선개미자리와 민개미자리를 발견하였다. 국내에서 생육하는 개미자리속 식물은 모두 Spergella절에 속하는 5수성이지만 발견된 두 분류군은 4수성을 나타내는 Saginella절에 속한다. 또한 결실기의 꽃받침잎과 종자 등 형태학적 형질에서 국내 생육하는 개미자리속 식물과 큰 차이를 보였다. 본 종들의 명확한 실체 규명을 위해 형태적 주요 특성을 국외 도감, 문헌 등을 활용하여 비교 관찰하였다. 그 결과, 형태적으로 선개미자리는 엽연에 털이 있고, 꽃받침잎이 수평으로 펴지며, 가장자리가 적색이고, 종자 표면의 돌기가 볼록하다. 민개미자리는 소화경이 개화기에 휘어지고, 결실기에 직립하며, 꽃받침잎은 넓은 난형이고, 가장자리가 백색또는 황록색이며, 종자의 돌기가 납작한 특징으로 구분된다. 분자생물학적 분석에서 채집된 19 개체군은 Genbank에 등록된개미자리속 유전정보와 함께각각의 종으로 유집되어, 국내 분포하는 분류군의 실체를 지지하였다. Abstract - Recently, in several regions of Korea, we discovered the occurrence of Sagina micropetala Rauschert and S. procumbens L. All the plants of the genus Sagina growing in Korea are 5-merous and belong to the sect. Spergella. However, the two taxa we discovered belong to the sect. Saginella and are 4-merous. In addition, morphological characteristics such as sepals during the fruiting season and seeds were significantly different from those of species of the genus Sagina that occur in Korea. To clearly identify these species, we compared and observed their primary morphological characteristics using illustrated books and literature. Morphologically, S. micropetala exhibits the following traits: pubescence along the leaf margin, horizontally spreading sepals with red margins, and convex protrusions on the seed surface. In contrast, S. procumbens can be distinguished by its pedicels, which are curved during the flowering season and erect during the fruiting season. This plant also has broadly ovate sepals with white or yellowish-green margins, and flat seed surface protrusions. In terms of molecular analyses, 19 samples of Sagina were divided into two clades (S. micropetala and S. procumbens), confirming the taxonomic identity of the Sagina spp.

In this study, radioactivity quantitative analysis was performed on radon contained in cigarette, and the effective dose was calculated using the result value to determine the amount of exposure caused by smoking. A total of 5 types of cigarettes were sampled. Cigarette smoke was collected by using activated carbon, and tobacco were measured by homogenizing for quantitative analysis. For each sample, Bi-214 and Pb-214 were subjected to gamma nuclide analysis to observe the uranium-based radioactive material contained in cigarette, and a measurement time of 30,000 seconds was set for the sample based on the results of previous studies. As a result of measuring the radioactivity of tobacco, a maximum of 0.715 Bq/kg was derived, and in the case of cigarette smoke measured using activated carbon, a maximum of 3.652 Bq/kg was derived. Using this measurement, the average effective dose to the lungs is 0.938 mSv/y, and it was found that there is a possibility of receiving exposure up to 1.099 mSv/y depending on the type of tobacco. It was found that the exposure dose due to cigarette occupies a large proportion of the annual effective dose limit for the general public. Therefore, more diverse studies on radioactive substances in cigarette are needed, and measures to monitor and reduce the incidental exposure to radon should be established.

필수지방산 결핍이 유도된 기니피그에서 보라지유와 홍화유 섭취의 표피 과증식 억제 및 세라마이드 대사에 미치는 효과 비교

이세령(Lee, Se Ryung),조윤희(Cho, Yunhi) 한국영양학회 2015 Journal of Nutrition and Health Vol.48 No.4

본 연구에서는 기니피그에 8주간 필수지방산 결핍 식이공급에 의해 표피 과증식을 유도한 후 계속된 2주간의 보라지유 또는 홍화유 식이 공급에 의한 과증식 억제 및 Cer, GlcCer, SM의 표피 함량 및 세라마이드 대사 관련 효소들의 단백질 발현 변화를 정상대조군인 BO군 및 필수지방산결핍 군인 HCO군과 비교하였으며 그 결과는 다음과 같다. 1. 8주간의 필수지방산 결핍 식이 공급 후 계속된 2주간의 보라지유 식이 공급 (HCO + BO군)은 2주간의 홍화유 식이 공급에 (HCO + SO군) 비해 더욱 현저히 표피 과증식을 억제하였다. 2. 10주간 필수지방산 결핍식이를 공급한 HCO군은 정상대조군인 BO군에 비해 Cer의 총 함량 및 Cer1/2/5/6/7, GlcCer-A/B의 함량이 유의적으로 감소되었다. HCO + BO군의 Cer과 GlcCer의 총 함량 및 Cer1/2, GlcCer-A/B, SM1의 함량은 HCO군에 비해 유의적으로 증가한 반면 HCO + SO군의 이들 함량은 HCO군과 유사하였다. GlcCer-C/D, SM의 총 함량 및 SM 2/3의 함량은 군간 변화가 없었다. 3. HCO군에서는 GCase 발현이 감소한 반면 HCO + BO군에서는 현저히 증가하였다. HCO + SO군의 aSMase의 단백질 발현이 HCO군에 비해 유의적으로 증가하였으나 aCDase의 발현 또한 다른 군에 비해 현저히 증가하였다. HCO + BO군과 HCO + SO군 모두 SPT의 단백질 발현이 HCO군에 비해 유의적으로 증가하였다. 결론적으로 표피 과증식이 유도된 기니피그에 보라지유식이 공급은 GlcCer-A/B을 포함하는 GlcCer 총 함량, SM1 및 GCase의 발현 증가와 더불어 Cer1/2를 포함하는 Cer 총 함량을 증가시켜 궁극적으로 표피 과증식을 현저히 억제하였다. Purpose: Borage oil (BO) and safflower oil (SO) are efficacious in reversing epidermal hyperproliferation, which is caused by the disruption of epidermal barrier. In this study, we compared the antiproliferative effect of dietary BO and SO. Altered metabolism of ceramide (Cer), the major lipid of epidermal barrier, was further determined by measurement of epidermal levels of individual Cer, glucosylceramide (GlcCer), and sphingomyelin (SM) species, and protein expression of Cer metabolizing enzymes. Methods: Epidermal hyperproliferation was induced in guinea pigs by a hydrogenated coconut diet (HCO) for 8 weeks. Subsequently, animals were fed diets of either BO (group HCO + BO) or SO (group HCO + SO) for 2 weeks. As controls, animals were fed BO (group BO) or HCO (group HCO) diets for 10 weeks. Results: Epidermal hyperproliferation was reversed in groups HCO + BO (67.6% of group HCO) and HCO + SO (84.5% of group HCO). Epidermal levels of Cer1/2, GlcCer-A/B, and β-glucocerebrosidase (GCase), an enzyme of GlcCer hydrolysis for Cer generation, were higher in group HCO + BO than in group HCO, and increased to levels similar to those of group BO. In addition, epidermal levels of SM1, serine palmitoyltransferase (SPT), and acidic sphingomyelinase (aSMase), enzymes of de novo Cer synthesis and SM hydrolysis for Cer generation, but not of Cer3-7, were higher in group HCO + BO than in group HCO. Despite an increase of SPT and aSMase in group HCO + SO to levels higher than in group HCO, epidermal levels of Cer1-7, GlcCer-A/B, and GCase were similar in these two groups. Notably, acidic ceramidase, an enzyme of Cer degradation, was highly expressed in group HCO + SO. Epidermal levels of GlcCer-C/D and SM-2/3 did not differ among groups. Conclusion: Dietary BO was more prominent for reversing epidermal hyperproliferation by enhancing Cer metabolism with increased levels of Cer1/2, GlcCer-A/B, and SM1 species, and of GCase proteins.

김태희,하영호,이세령,Sang-Chul KIM,이정심,김동갑,김혁진 국립중앙과학관 2023 Journal of Asia-Pacific Biodiversity Vol.16 No.2

Aconitum quelpaertense Nakai is an endemic species of Jeju Island of South Korea. Here, we characterized complete chloroplast genome sequence of A. quelpaertense and inferred its phylogenetic position within the genus Aconitum. The complete chloroplast genome was 155,636 bp in length with typical quadri partite structure. Length of large single copy was 86,695 bp, whereas small single copy was 17,087 bp. A pair of inverted repeats were 25,927 bp. In total, 128 genes were encoded and comprising 83 protein coding genes, 37 tRNA genes and eight rRNA genes. rpl32 and rps16 genes were pseudogenized in this plastome. The phylogenetic analysis based on complete chloroplast genome sequences showed that A. quelpaertense was closely related to another endemic species of South Korea, A. pseudolaeve.

강은수,정수영,이세령,손동찬,김상철 국립중앙과학관 2023 Journal of Asia-Pacific Biodiversity Vol.16 No.4

We determined the complete chloroplast genome sequence of Epilobium parviflorum Schreb. The genome is 161,284 bp in length [including a large single copy (LSC): 89,063 bp; a small single copy (SSC): 17,323 bp; and two inverted repeat (IR) regions: 27,499 bp] with 38.1% GC content and contains 84 coding genes (CDS), 37 transfer RNA genes, and 8 rRNA genes. Among them, infA was annotated as a pseudogene. The maximum-likelihood analysis based on CDS sequences of chloroplast genomes was conducted for investigating the phylogenetic relationship among Epilobium and related species. The results showed a close relationship between E. parviflorum and E. hirsutum L. Our study added new genetic information of E. parviflorum and helped to understand the relationship with related species and evolutionary history in Onagraceae.
