  • 꿀풀과의 Lycopus charkeviczii Prob.가 제주도를 제외한 전국에서 발견되었다. 본 종은 소견과보다 긴 숙존하는 악편, 좁은 피침형에서 장타원상 피침형인 잎과 같은 공유 형질을 가지고 있어 쉽싸리(L. lucidus)와 유사하다. 그러나 심열하는 악, 상부는 불규칙한 파상이며 선점이 없거나 드물게 있는 소견과인 특징으로 뚜렷이 구분된다. 국명은 생육지를 고려하여 '산쉽싸리'로 신칭하였고, 이에 대한 기재, 도해, 사진 및 검색표를 제시하였다.

  • Sophorae Flos (SF), a composite of flowers and flower-buds of Sophora japonica, has long been used in traditional Korean and Chinese medicines for the treatment of hemostasis and inflammation. In this study, we investigated anti-inflammatory effect of four EtOH extracts at the difference in blooming stages of flowers on LPS-induced inflammation in RAW264.7 cells. We classified the flowers of Sophora japonica with SF-1 (length of flower is shorter than calyx), SF-2 (length of calyx is shorter than flower), SF-3 (full bloom), and SF-4 (not blooming at all). We examined HPLC analysis, whether quercetin and rutin are major component of these Sophorae Flos extracts or not. As a result, SF-1 contained quercetin, but the others did not. In addition, quercetin, SF-1, and SF-4 act on the suppression of pro-inflammatory mediators including inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-2, nitric oxide (NO), prostaglandin E2 ($PGE_2$) against lipopolysaccharide (LPS)-induced activation in RAW264.7 cells. Of these, SF-1 showed the best anti-inflammatory effect. These results suggest that Sophorae Flos with the highest content of quercetin would be used for the treatment of various inflammation diseases.

  • Lycopus속 15종의 화판(petal)과 악편(sepal)의 미세형태를 주사전자현미경과 실체현미경으로 관찰하여 그 분류학적 유용성을 검토하였다. Lycopus속 분류군들의 화관과 악에 분포하는 모용과 선모는 단세포 원주모(unicellular cylindrical trichome), 표면에 돌기가 있는 단세포 모용(unicellular trichome with papillae), 다세포 모용(simple multicellular trichome), 두상선모(capitate glandular trichome) 및 방패형 선모(peltate glandular trichome) 등 5 종류로 나타났으며, 모용의 종류, 분포, 밀도가 분류군마다 다르게 나타났다. 화관 안쪽면에 단세포 원주모(unicellular cylindrical trichome)의 분포 정도가 각 분류군마다 다르게 나타나, 그 분포 부위에 따라 4가지 유형으로 나눌 수 있었다. 악(calyx)은 악편이 갈라지는 정도와 악편 정단(apex)의 모양으로 4가지 형태로 구분할 수 있었다. 화판과 악편의 안쪽 빛 바깥면을 구성하는 세포의 형태는 그 위치와 분류군에 따라 다양하게 나타났다. 끝으로 관찰된 Lycopus속의 화판 및 악편 미세형태를 검토한 결과 종간 식별에 유용하였다.

  • Daphne L. (Thymelaceae) comprises about 95 species distributing worldwide from N Africa, N India, SE Asia to E Asia and the coast of the Mediterranean of Europe. In Korea, five species of this genus have been described. In this study, we included four species (D. genkwa, D. pseudomezereum, D. kiusiana, D. jejudoensis) from Korea, excluding cultivated D. odora. The morphological characters through local surveys and the re-classification of the specimens collected in the Korea National Herbarium (KH) were carried out and distribution maps for each taxon were also prepared. The major characters include habit, trichomes in winter bud, leaf, and twig, phyllotaxis, inflorescence, size of calyx lobe and trichomes in the calyx tube, etc. The distribution map showed that D. genkwa is mainly distributed in the coastal area of Hwanghaenam-do, Pyeongannam-do, Jeollabuk-do and Jeollanam-do, whereas D. pseudomezereum is distributed in the limestone zone of Gangwon-do, Jeollabuk-do, and Gyeongsangbuk-do. Similarly, D. kiusiana is mostly found in Jeollanam-do, Gyeongsangnam-do, and Jeju-do. In addition, D. jejudoensis is known to be distributed in forests of Murueng, Andeok, and Seonheul-ri in Jeju-do, but recently, new habitat is discovered in the island forest areas of Jeollanam-do. However, some of these individuals showed the characteristics of D. kiusiana, thus before come to any conclusion detailed taxonomic review of D. jejudoensis and D. kiusiana is required.

  • 제주도 서귀포시에서 발견된 Oldenlandia brachypoda DC.를 한반도 미기록종으로 확인하여 보고하고자 한다. 본 종은 속 내의 근연종인 백운풀(Oldenlandia diffusa)에 비해 소화경은 짧고, 돌기가 없으며, 엽액에서 1-3개의 꽃이 피고, 수술대는 0.5-0.8 mm로 길며, 악편은 삼각형, 성숙시 열매의 상부는 팽창하지 않는 점에서 구분된다. 국명은 자생지가 제주도인 점을 고려하여 '제주백운풀'로 명명하였으며, 주요 형질에 대한 도해와 기재, 검색표를 제시하였다.

  • The morphological characteristics of the Korean Scopolia japonica Maxim., commonly known as 'Mi-chi-gwang-i-pul' in Korean, were re-evaluated in comparison with results from previous research, while the distribution map was formulated according to existing flora and voucher specimens. The result of the re-evaluation has shown that there are some distinctive discrepancies compared to the previous reports of some characteristics such as the color of the basal stem, numbers of lateral veins, apex shape of calyx and corolla including the color of corolla. The Korean Scopolia japonica Maxim is found throughout Korea except Jeju-do province. The intra-specific species such as S. parviflora (Dunn.) Nakai, S. lutescens Y.N. Lee and S. kwangdokensis Y.N. Lee were treated as synonyms of S. japonica Maxim. in this research.

  • The calyceal diverticulum is a cystic cavity lined by a transitional epithelium, is encased within the renal substance, and is situated peripheral to a minor calyx, to which it is connected by a narrow channel. Both congenital and acquired factors have been suggested to explain the formation of a calyceal diverticulum. We experienced a case of a huge calyceal diverticulum that was newly developed after a renal injury.

  • The structures and energies of p-tert-butylcalix[4]crown-6-ether(1) in various conformers and their alkyl ammonium complexes have been calculated by ab initio HF/6-31G quantum mechanics method. We have tried to obtain the relative affinity of partial-cone and 1,3-alternate conformers of 1 for alkyl ammonium guests by comparison with its cone-shaped analogue. We have also calculated the relative complexation efficiency of these host-guest complexes focusing on the binding sites of $crown-\sigma-enther$ moiety or benzene-rings pocket of the host molecule 1. These calculations revealed that the crown moiey has better complexation efficiency than upper rim part of calyx[4]arene that is in similar trend to the cone-shaped complexes.

  • Luffa acutanqula var. amara exhibits floral and extrafloral nectaries. The floral nectaries are restricted to the torus of the male flowers, while the extrafloral nectaries are observed on foliage leaves, probract, outer surface of calyx and pedicels. The floral nectaries develop from a group of epidermal and sub-epidermal initials which differentiate into secretory and subsecretory zones respectively during further divisions. The extrafloral nectary initiates from a single papillate nectary initial which gives rise to mature nectary comprising stalk layer, secretory and subsecretory tissues. Both the floral and extrafloral nectaries are vascularized. Interactions between insect-visitors and the plant with special reference to their functions are also discussed.
