Tetragonia tetragonoides (Aizoaceae) has been known as an anti-cancer agent. The activation of proteinase-activated receptor-2 (PAR-2) by trypsin appears to play a role in inflammation. In the present study, we examined the inhibitory effects of Tetragonia tetragonoides water extract (TTWE) on the production of tumor necrosis $factor-{\alpha}\;(TNF-{\alpha})$ and tryptase in trypsin-stimulated human leukemic mast cells (HMC-1) expressing PAR-2. HMC-1 cells were stimulated with trypsin in the presence or absence of TTWE (10, 100, and $1000\;{\mu}g/ml$). The level of $TNF-{\alpha}$ secretion from HMC-1 cells was measured by enzyme-linked immunosorbent assay (ELISA). $TNF-{\alpha}$ and tryptase mRNA expression were examined by reverse transcription-PCR. Also, extracellular signal-regulated kinese (ERK) activation was assessed by Western blot analysis. Trypsin activity was measured using the substrate Bz-DL-Arg-p-nitroanilide (BAPNA). It was observed that $TNF-{\alpha}$ secretion, tryptase mRNA and $TNF-{\alpha}$ mRNA expression in trypsin-stimulated HMC-1 cells were inhibited by pretreatment of TTWE ($1000\;{\mu}g/ml$). Furthermore, the pretreatment of TTWE ($1000\;{\mu}g/ml$) resulted in the reduction of ERK phosphorylation and trypsin activity. These results suggest hat TTWE might have the inhibitory effects on the PAR-2-dependent inflammation processes and it is likely to function as PAR-2 antagonist.

In order to compare species-specific calcium metabolism, we collected 127 species belonging to 40 different families grown on various habitats including saline, limestone, wetland during the 1996 vegetation period, and analyzed their inorganic ion contents. Plants investigated were divided into 5 groups according to their physiological properties: 1) Chenopodiaceae, Aizoaceae, Caryophyllaceae, Portulacaceae and Phytolaccaceae of Centrospermales and Polygonaceae (Polygonales had a little water-soluble $Ca^{2+}$ but contained high contents of insoluble $Ca^{2+}$ particularly as Ca-oxalate (Chenopodiaceae type), 2) Some plant species such as Rosaceae produced oxalate in amounts insufficient to precipitate all incoming $Ca^{2+}$ and thus contained a surplus of dissolved $Ca^{2+}$ (Rosaceae type), 3) The contents of water-soluble $Ca^{2+}$ in plant species of Crassulaceae. Plantaginaceae, Asclepiadaceae, and Zygophyllaceae were equal to or greater than those of K ($K/Ca{\leq}1$; Crassulaceae type), and 4) K/Ca ratios of Compositae were significantly fluctuated depending on species and soil $Ca^{2+}$ level of their habitats (Compositae type). 5) Certain monocots (Gramineae, Cyperaceae, Juncaceae), in contrast to the dicotyledonous plant families mentioned above, showed a very distinct type of calcium metabolism, that is, the K/Ca ratios of 8~10 were maintained indifferently in the species and their habitat types (Graminae type). These results plants within the same taxon have similar physiological aspects as weel as morphological attributes. To understand calcium metabolism of certain plant species, therefore, it is desirable to approach on the basis of physiological concept (calciotroph or calciophobe) rather than the ecological one (calcicole or calcifuge).

Lampranthus spectabilis is an ornamental plant which belongs to one of the Aizoaceae family as an one-year herb. There are no illustrations on the references that Lampranthus spectabilis has been made use for the purpose of the medicinal plant among the traditional herb doctors and the laymen. However, it has the specific characteristics to be analogous to the Cactaceae family in the botanical classification. Besides, mescaline, the main ingredient of Peyote cactus, demonstrates the sympathomimetic effect as well as the psychotomimetic effect. The authors called our attention to the resemblance to the botanical family between Aisoaceae and Cactaceae, and made a survey whether the alcohol extract of Lampranthus spectabilis might possess any pharmacological effect on the isolated heart of clam or not. The results of the experiment were as follows. 1. Administration of LX to the isolated heart of clam produced an inhibitory effect on the cardiac motility in proportion to its concentration $10^{-4}$, $5{\times}10^{-4}$ and $10^{-3}\;g/ml$ respectively. 2. Administration of LX $5{\times}10^{-4$ and $10^{-3}\;g/ml$ produced the blockade effect on the cardiac motility pretreated with serotonin $10^{-7}$ and $10^{-4}\;g/ml$, as well as with methysergide $10^{-6}$ and $10^{-5}\;g/ml$. 3. Administration of LX $5{\times}10^{-4}\;g/ml$ produced no effect on the cardiac motility pretreated with acetylcholine $10^{-7}\;g/ml$. 4. Administration of LX $5{\times}10^{-4}\;g/ml$ produced the blockade effect on the cardiac motility pretreated with barium chloride $10^{-4}\;g/ml$, as well as with prostaglandin $20\;{\mu}g$. Consequently, it is concluded that the alcohol extract of Lampranthus spectabilis has an effect of depression on the motility of the isolated heart of clam. Its mechanism of action might be due to a direct action on the heart.

32종의 해안식물(주로 염생식물)에 대한 유리아미노산 및 총질소함량을 조사하였다. 몇몇 종(참골무꽃과 해란초)을 제외한 모든 식물체는 Pro을 함유하였으나, 번행초, 등골나물아재비 및 갯무에서만, 높은 함량을 나타내어, 이들 식물에서 Pro은 세포질성 삼투물질로 작용하는 것으로 생각된다. 그러나 등대풀, 갯무, 갯방풍, 갯기름나물, 통보리사초, 왕잔디, 갯잔디 등의 식물은 Pro 보다는 hydroxylproline (OH-Pro)을 상당량 축적하였다. 총 아미노산은 갯개미취, 갯질경, 해란초, 순비기나무 및 특히 명아주과와 돌나물과 식물에서 낮은 값을 보였다. 또한 번행초, 등대풀, 갯무, 명아주과 및 콩과 식물은 보편적으로 총 질소 및 수용성 질소함량이 높았으나, 참골무꽃, 해란초, 순비기나무, 통보리사초 및 벼과 식물은 낮은 수준의 질소함량을 보였다. 대부분의 해안식물에서 유리아미노산은 총질소함량에 차지하는 비율이 낮았지만, 등대풀, 모래지치 및 둥근바위솔의 경우 아미노산 질소가 총질소함량의 25∼30%를 차지하였다. 결론적으로, 몇몇 예외는 있지만 세포질성 삼투물질로 널리 알려진 Pro은 조사된 해안식물의 유리아미노산 풀(pool)에서 유의한 몫을 차지하지 않는 것으로 여겨진다.

본 연구에서는 아이스플랜트의 기능성 식품소재로의 우수성을 알아보기 위하여 유리아미노산을 분석하고 추출용매에 따른 ACE 저해 활성과 3T3-L1 전지방세포에 대한 분화 억제 활성을 검증하였다. 아이스플랜트의 유리아미노산 총 함량은 32.57 mg/g이었으며, L-alanine 4.64 mg/g으로 가장 많이 함유되어 있었고 혈압저하 및 이뇨효과를 가지는 ${\gamma}$-aminobutyric acid는 2.60 mg/g을 함유한 것으로 나타났다. 아이스플랜트 용매분획별 ACE 저해 활성은 ethyl acetate 분획과 chloroform 분획에서 각각 $33.17{\pm}3.20{\sim}88.19{\pm}3.20%$, $23.72{\pm}2.89{\sim}86.78{\pm}2.24%$로 높은 활성을 나타내었고 butanol, water 및 hexane 분획에서는 각각 $8.86{\pm}1.20{\sim}41.21{\pm}2.49%$, $3.24{\pm}1.50{\sim}36.01{\pm}1.38%$, $-2.46{\pm}0.37~31.28{\pm}2.86%$로 나타났다. Ethyl acetate 분획과 chloroform 분획은 양성대조군인 Captopril(R)($19.51{\pm}3.44{\sim}84.72{\pm}1.06%$) 및 Enalapril(R)($24.93{\pm}1.12{\sim}91.32{\pm}3.62%$)과 유사한 저해 활성을 나타내었다. 3T3-L1 지방전구세포의 지방구 생성억제 정도를 측정한 결과 ethyl acetate 분획과 butanol 분획에서 대조군에 비하여 $53.00{\pm}0.45{\sim}65.75{\pm}0.31%$와 $44.16{\pm}0.29{\sim}63.32{\pm}0.36%$로 가장 많이 감소하였고 chloroform 분획과 hexane 분획은 $38.33{\pm}0.09{\sim}56.55{\pm}0.50%$, $31.17{\pm}0.50{\sim}55.10{\pm}1.93%$, water 분획은 $26.32{\pm}2.27{\sim}49.48{\pm}0.05%$로 모든 분획에서 농도 의존적으로 3T3-L1 지방전구세포의 지방 축적을 억제하는 것으로 확인하였다. 이상의 결과로부터 아이스플랜트는 다양한 생리활성 물질을 함유하고 있으며, 항고혈압과 항비만의 생리활성 효과를 가지는 것을 확인하여 기능성 식품 소재로서의 가치가 뛰어나다고 판단된다.
