  • Oldenlandia diffusa, Cremastra appendiculata and Fritillaria thunbergii are widely distributed in the Korea, China and Japan, and has been used in traditional medicine for various diseases, such as pharyngolaryngitis, tonsillitis, goiter and stomach ulcer. However, the anti-cancer activities in human breast cancer have not been clearly elucidated yet. In this study, it was compared the in vitro cytotoxic effects of single and complex treatment of O. diffusa, C. appendiculata and F. thunbergii. We treat human breast cancer MCF-7 cells with O. diffusa, C. appendiculata and F. thunbergii. And we evaluated viability, growth inhibition, morphological changes, apoptotic bodies formation, measurement of the cell cycle and formation of DNA fragmentation of these cells. It was found that single treatment of O. diffusa could inhibit the cell proliferation in human breast cancer MCF-7 cells. However, complex treatment of O. diffusa, C. appendiculata and F. thunbergii is weakly or not affect the cell proliferation of MCF-7 cells. And anti-proliferative effects of O. diffusa in MCF-7 cells was associated with G1 arrest of cell cycle. These findings suggest that O. diffusa may be a potential chemotherapeutic agent for the control of human breast cancer cells and further studies will be needed to identify the molecular mechanisms.

  • O. diffusa, C. appendiculata and F. thunbergii are reported to possess many pharmacological activities including anti-oxidant, anti-inflammatory, anti-hypertension, anti-diabetic and anti-cancer effects. However, their anti-cancer activities in human breast cancer have not been clearly elucidated yet. Objectives: In the present study, we compared the in vitro cytotoxic effects of single and complex treatment of O. diffusa, C. appendiculata and F. thunbergii in human breast cancer MDA-MB-231 cells. Methods: After we treated human breast cancer MDA-MB-231 cells with O. diffusa, C. appendiculata and F. thunbergii. we evaluated viability, growth inhibition, morphological changes, apoptotic body formation, measurement of the cell cycle and formation of DNA fragmentation of these cells. Results: We found that single treatment of O. diffusa and F. thunbergii could inhibit cell proliferation in human breast cancer MDA-MB-231 cells. However, complex treatment of O. diffusa, C. appendiculata and F. thunbergii had weak or no effect on the cell proliferation of MDA-MB-231 cells. The first, anti-proliferative effects of O. diffusa in MDA-MB-231 cells was associated with G2/M arrest of cell cycle and apoptotic cell death. The second, anti-proliferative effect of F. thunbergii in MDA-MB-231 cells was associated with apoptotic cell death. Conclusions: Taken together, these findings suggest that O. diffusa and F. thunbergii may be a potential chemotherapeutic agent for the control of human breast cancer cells, further studies will be needed to identify the molecular mechanisms.

  • Morphological changes of flowers and insect visitors were observed to investigate pollinator of Caesalpinia decapetala. The flowers of C. decapetala are protandrous. Functionally, the flower is changed from male to female. As a male, pollen grain is released after anther dehisced while style is immature. After completed pollen grain release, the style starts to lengthen. It helps the stigma to easily touch the carpenter bee's thorax covered with pollen grain. At this time, flower functions as a female. The majority of taxa and individuals observed were Hymenoptera. The most frequent visitor was the Xylocopa appendiculata circumvolans, carpenter bee. Carpenter bees exhibited only typical pollinator behavior among flower visitors, with touching reproductive organs and seeking nectar at the same time. The pollination behavior is as follows. Soon after carpenter bees perceived guide mark, they foraged rightward and grasped style and stamens with legs and they inserted proboscis into standard petal to seek nectar. With this behavior, the pollen grains of the male flower transfer to the ventral thorax of the carpenter bee. As the carpenter bee moves to another female flower, the deposited pollen grains are delivered to the stigma.

  • We report the meiotic chromosome numbers of four Carex taxa from Korean populations. Three are the first reports made on taxa from Korean populations: Carex appendiculata (Trautv. & C. A. Mey.) $K{\ddot{u}}k$. ($n=27_{II}$), C. fernaldiana H. $L{\acute{e}}v$. & Vaniot ($n=33_{II}$), and C. metallica H.$L{\acute{e}}v$. ($n=15_{II}$). Reports on the other species expand the range of variation in the chromosome number within a taxon, C. miyabei Franch. (n = $43_{II}$, $44_{II}$, $45_{II}$). Carex L. (Cyperaceae) consists of more than 2,000 species worldwide and is the most species-rich genus in Korea. The species diversity in the genus has been hypothesized to be associated with the chromosome variation, but chromosome information pertaining to Korean Carex taxa is not well known. This report updates the chromosome number inventory on Korean Carex to 24 out of 180 taxa.

  • Siphonophores are unique, gelatinous zooplankton, which many individuals gather and live like one "Superorganism". The role of individuals in the colony differs greatly depending on their morphological difference, making them more unique. In this study, we report four species belonging to Diphyidae Quoy and Gaimard, 1827 sampled from the South Sea and off Jeju Island, Korea. Two Chelophyes Totton, 1932 (C. appendiculata (Eschscholtz, 1829); C. contorta (Lens and van Riemsdijk, 1908)) and two Eudoxoides Huxley, 1859 (E. mitra (Huxley, 1859); E. spiralis (Bigelow, 1911)) species are described with multi-focus stacked digital images. Our findings update the confirmed order Siphonophorae Eschscholtz, 1829 in Korea to be three suborders, five families, eight genera, and 13 species. In addition, we summarize the synonyms and global distributions of these four newly recorded species in Korean waters.

  • In order to estimate accurate originality of the important crude drugs, Gastrodia, Dendrobium, Bletilla and Cremastra spp. were investigated comparing their morphological, anatomical and physicochemical characteristics and antibacterial, antifungal activities. The results of the studies as follows: 1. In morphological and anatomical studies, Korean Gastrodia contained more mucilage duct and symbiotic fungi than imported Gastrodia. Korean Dendrobium contained starch grains but without starch grains in the imported Dendrobium from China enclosed with thicken silicified wall. The corm of Cremasta appendiculata contained raphides of bundles with mucilage while the bulbs of Tulipa edulis contained several various starch grains form. 2. In physiological and TLC analysis, crude drugs in Orchidaceae contained common constituents with fluorescence and much mucilage. 3. The EtOH extracts of Gastrodia, Dendrobium, Bletilla, Cremastra showed antibacterial activities against B. subtilis and E. coli (Dendrobium>Gastrodia>Bletilla>Cremastra). But, no antifungal activities against C. albicans, A. niger were observed.

  • 제비동자꽃(Lychnis wilfordii (Regel) Maxim.)은 주로 고위도의 이탄습지에 분포하는 전문종이다. 우리나라에서는 2개 지역에 고립되어 분포한다. 본 연구에서는 생육지 특성, 생장특성 및 자가화합성 그리고 안정적인 개체군을 유지하고 있는 용늪습지보호지역에서 개체군의 지속에 관여하는 내적 동태를 평가하였다. 분포지의 식생환경은 용늪습지보호지역과 평창군 대관령면 분포지 사이에 뚜렷한 차이가 있었다. 화분매개충의 방문에 의해 종자의 생산이 촉진되기는 하지만 자가화합성을 함께 소유하였다. 토양의 유기물함량이 높은 조건에서 다수의 겨울눈을 생성하였고, 줄기 수, 열매 수가 최대에 달하였다. 그렇지만 유기물함량이 낮은 조건에서도 생장하고 개화하여 종자를 생산하였다. 용늪습지보호지역에서 제비동자꽃은 고층습원에는 분포하지 않았고 뚝사초가 형성하는 사초기둥이 발달한 저층습원에 분포하였다. 제비동자꽃은 이 공간에서도 사초기둥의 상단부에 주로 분포하였다. 따라서 뚝사초가 형성하는 사초기둥의 생성, 성장 및 소멸은 이 공간에 분포하는 식물의 정착, 성장, 소멸과 밀접한 연관이 있는 것으로 판단되었다. 현재 용늪습지보호지역은 제비동자꽃이 분포하는 사초기둥이 발달한 공간이 넓게 분포하고 있고 소멸과 재정착의 과정이 잘 이루어지는 것으로 평가되었다. 그러므로 현재와 같은 생태적 과정이 잘 유지된다면 용늪습지보호지역의 제비동자꽃 개체군은 오랜 기간에 걸쳐 지속 가능할 것으로 예상되었다.

  • 본 연구는 인천광역시 강화군에 위치한 퇴모·혈구산의 관속식물상과 강화도 및 주변 지역의 외래식물 등을 파악하여, 조사된 식물들의 체계적인 관리와 생물다양성 보전을 위한 기초자료로 활용하기 위하여 조사를 실시하였다. 조사는 2019년 3월부터 2020년 10월까지 총 13회에 걸쳐 실시되었다. 퇴모·혈구산 일대의 관속식물상은 총 101과 321속 517종 13아종 38변종 5품종 573분류군으로 파악되었다. 이는 우리나라 관속식물 총 4,641분류군의 약 12.35%로 나타났다. 퇴모·혈구산에서 확인된 한반도 북방계식물은 청나래고사리 등 68분류군, 한반도 특산식물은 늦둥굴레 등 10분류군, IUCN 지정 희귀식물은 께묵 등 총 9분류군이 확인되었다. 식물구계학적 특정식물은 총 69분류군으로 파악되었다. IV등급은 뚝사초 등 3분류군, III등급은 종덩굴 등 14분류군이 확인되었다. 연구 대상지에서 출현한 귀화식물은 개망초, 돼지풀, 망초 등 63분류군으로 확인되었다. 개망초, 돼지풀, 망초 3종은 강화도뿐만 아니라 주변 지역인 석모도, 교동도 김포 등에도 전방위적으로 확산된 것으로 파악되었다. 그리고 가시상추, 가시박, 애기수영 등 생태계교란식물이 퇴모·혈구산에 처음으로 보고되어 퇴모·혈구산 내 특기할만한 식물 등 자생식물에 대해 중장기적인 보전 대책을 수립하고 정기적으로 물리적인 제거 등의 관리방안 대책을 조기에 마련하여야 할 것이다.
