  • The effects of water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower on serum lipid concentrations were evaluated in rats. Forty-eight male Sprague-Dawley rats weighing l00±l0 g were divided into six groups and fed high fat diets for six weeks. Experimental groups were administered with following diets; Control diet, animal, plant high fat diet and control and high fat diets with 2% water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower. Tissue weights of liver, lung, stomach, heart, kidney and spleen of high fat diet exposed rats were reduced by water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups. The concentrations of serum triglyceride in rats fed the water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower were lower than those in other groups. The concentrations of total cholesterol in water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower group were lower than those in high fat diet groups. The concentrations of HDL-cholesterol in serum of the water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups were significantly higher than those of other groups. The levels of LDL-cholesterol in serum of the water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups were tended to be lower than those of other groups. GPT and GOT activities were decreased in water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups and than in the high fat group. LDH activity was lower in the water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups than in the high fat group. These results suggest that water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups may reduce elevated levels of serum lipid concentrations in rats fed high fat diets.

  • Invasion and metastasis is the main cause of cancer mortality. Angiogenesis is a prerequisite for the tumor growth and metastasis. Matrix metalloproteinases (MMPs) are the key enzymes playing in the invasive growth and metastasis of cancer as well as angiogenesis. Xanthohumol, a prenylated chalcone of the Hop plant (Humulus lupulus L), has been reported to suppress cancer invasion and angiogenesis. In the present study, we investigated the antiinvasive effects of xanthohumol (1) and its synthetic derivatives, 4'-O-methylxanthohumol SEM ether (2), xanthohumol C (3), and xanthohumol C MOM ether (4) in relation to MMP expression in HT-1080 human fibrosarcoma cells. The compound 1 and its derivative, 3 and 4, significantly inhibited serum-induced HT-1080 cell invasion, and 12-O-tetradecanoylphorbol-13-acetate (TPA)-enhanced activity and expression level of MMP-2 and MMP-9 in a concentration-dependant manner. In addition, they inhibited TPA-enhanced expression of MT1-MMP with relatively weak inhibition in tissue inhibitor of metalloproteinase (TIMP)-1 and TIMP-2 level. The compound 1 significantly decreased the cell viability, whereas the derivatives, 2 and 3 showed no cytotoxicity, and compound 4 showed slight cytotoxicity in the cells. Furthermore, in a chick chorioallantoic membrane (CAM) assay, the derivatives 3 and 4 dose-dependently suppressed vascular endothelial growth factor (VEGF)-induced angiogenesis, which is similar to that of compound 1. Taken together, the results indicate that compounds 3 and 4 may be valuable anti-angiogenic agents in the treatment of chronic diseases such as cancer and inflammation working through suppression of MMP-2 and MMP-9.

  • A cDNA clone for a salicylic acid-induced gene in Chinese cabbage (Brassica rapa subsp. pekinensis) was isolated and characterized. The cabbage gene, designated Br-sil1 (for $\underline{B}$rassica $\underline{r}$apa $\underline{s}$alicylate-$\underline{i}$nduced $\underline{l}$lipase-like 1 gene), encodes a putative lipase that has the family II lipase motif GDSxxDxG around the active site serine. A database search showed that plant genomes have a large number of genes that contain the family II lipase motif. The lipase-like proteins include a myrosinase-associated protein, an anther-specific proline-rich protein APG, a pollen coat protein EXL, and an early nodule-specific protein. The Br-sil1 gene is strongly induced by salicylic acid and a non-host pathogen, Pseudomonas syringae pv. tomato, that elicits a hypersensitive response in Chinese cabbage. Treatment of the cabbage leaves with BTH, methyl jasmonate, or ethephon showed that the Br-sil1 gene expression is induced by BTH, but not by methyl jasmonate or ethylene. This indicates that the cabbage gene is activated via a salicylic acid-dependent signaling pathway. An examination of the tissue-specific expression revealed that the induction of the Br-sil1 gene expression by BTH occurs in leaves and stems, but not in roots and flowers. Without the BTH treatment, however, the Br-sil1 gene is not expressed in any of the tissues that were examined.

  • The present study was to investigate the growth response and nutrient absorption in three willow species (Salix gracilistyla, S. koreensis and S. chaenomeloides) treated with nitrogen source (NH4+:NO3- rate; 200:0, 150:50, 100:100, 50:150, 200:0) for a period of 90days. The height, dry weight and chlorophyll contents of three species of willows were found to be highest at 50:150 (NH4+:NO3-) treatment. NO3--N was more effective than NH4+-N in the early growth of three species of willows. The increase in percentage of NO3--N handling, T-N, NO3--N in plant tissue increased. The analysis of C, N and mineral content in various parts revealed that the amounts of C, N, K, Ca and Mg were higher in leaves than those in the stems and the roots. However, the amount of NO3--N and P were higher in roots than those in the leaves and the stems. Salix koreensis was excellent, followed by S. chaenomeloides and S. gracilistyla in absorption of nitrate nitrogen. Higher percentage of NO3--N, the amounts of T-N, NO3--N, P2O5, K, Na, Ca, and pH in soil were decreased.

  • E. japonica is a well-known medicinal plant in Japan. The leaves of E. japonica were reported to have a hypoglycemic action. However, seeds of E. japonica are discarded and not used. To elucidate for anti-diabetic effects of E. japonica, Type 2 diabetic mice were allocated to control group, E. japonica leaf, and seed extract group. Animals were fed a 2018S Teklad global 18% protein rodent diet. Animals were received daily oral injections of E. japonica leaf or seed extract at a dose of 200 mg/kg body weight for 6 weeks. Body weight, food intake and water intake, and total adipose tissue weight of animals were significantly reduced by feeding of E. japonica leaf extract. All E. japonica extract groups significantly decreased fasting blood glucose, glycosylated hemoglobin levels, size of adipocytes and serum adiponectins. However, they did not have a beneficial effect on the serum triglyceride and cholesterol in the diabetic animals. These results suggest that E. japonica seed and leaf extracts have a antidiabetic effect by controlling of blood glucose and decrease of size of adipocytes in db/db mice and seed extract is more effective in hypoglycemic action than leaf extract.

  • Objectives: Allium jesdianum (Aj) is a medicinal plant that has highlighted pharmacological features. In this study, the effects of Aj extract were examined on acetaminophen (APAP)-induced hepatic failure in rats. Methods: Methanolic fraction of hydro-alcoholic extract of Aj was obtained by silica gel column chromatography method. Animals were randomly divided into four groups each containing six rats and treated by gavage as follows: the first and second groups received normal saline, the third and fourth groups were received with 50 and 100 mg/kg of Aj extract, respectively. After two consecutive weeks, the groups 2-4 were given a single dose of APAP (2 g/kg). After 48 hours, blood and liver samples were collected for biochemical and histological examinations. Results: The findings of the study demonstrated that APAP caused a significant increase in ALT (P < 0.001), AST (P < 0.001), LDH (P < 0.001), ALP (P < 0.001) serum levels, hepatic lipid peroxidation (LPO; P < 0.001) and nitric oxide (NO; P < 0.001). In this regard, APAP led to the depletion of the total antioxidant capacity (TAC; P < 0.001), glutathione and total thiol groups (TTGs; P < 0.001), and structural change in the liver. In the Aj extract groups, a considerable improvement was found in the hepatic function alongside the histopathologic changes. Conclusion: This investigation indicated that the influential effects of Aj extract in APAP-induced hepatic failure might depend on its effect on improving oxidant/antioxidant balance in hepatic tissue.

  • In this study, the bio-phytoremediation and phytoremediation technologies were applied to the soils contaminated with total petroleum hydrocarbons (TPH) and heavy metals to evaluate the remediation efficacy from May 2012 to December 2013. Poplar (Populus bonatii Levl.) and Sun Hemp (Crotalaria juncea L.) were selected and planted in phytoremediation practice. These plants were also utilized in the bio-phytoremediation practice, with the addition of earthworm (Eisenia fetida) and petroleum-degrading bacteria (Pseudomonos sp. NKNU01). Furthermore, physiological characteristics, such as photosynthesis rate and maximal photochemical yield, of all testing plants were also measured in order to assess their health conditions and tolerance levels in adverse environment. After 20 months of remedial practice, the results showed that bio-phytoremediation practice had a higher rate of TPH removal efficacy at 30-60 cm depth soil than that of phytoremediation. However, inconsistent results were discovered while analyzing the soil at 100 cm depth. The study also showed that the removal efficiency of heavy metals was lower than that of TPH after remediation treatment. The results from test field tissue sample analysis revealed that more Zinc than Chromium was absorbed and accumulated by the tested plants. Plant height measurements of Poplar and Sun Hemp showed that there were insignificant differences of growth between the plants in remediation plots and those in the control plot. Physiological data of Poplar also suggested it has higher tolerance level toward the contaminated soils. These results indicated that the two testing plants were healthy and suitable for this remediation study.
