  • A single specimen (220.4 mm SL) of the bandfish Acanthocepola indica was collected near Maemul Island, off southeastern Korea. This species is characterized by having a serrated posterior margin of preopercle and a black blotch on anterior part of dorsal fin. It differs from two other species, A. limbata and A. krusensternii, in having a deeper body, 88 dorsal fin rays, and 101 anal fin rays. Our specimen of A. indica is the first record of the species from Korea, for which we propose the new Korean name "Nam-bang-hong-gal-chi."

  • Calocybe indica, a tropical edible mushroom, is popular because it has good nutritive value and it can be cultivated commercially. The current investigation was undertaken to determine a suitable substrate and the appropriate thickness of casing materials for the cultivation of C. indica. Optimum mycelial growth was observed in coconut coir substrate. Primordia initiation with the different substrates and casing materials was observed between the 13th and 19th day. The maximum length of stalk was recorded from sugarcane leaf, while diameter of stalk and pileus, and thickness of pileus were found in rice straw substrate. The highest biological and economic yield, and biological efficiency were also obtained in the rice straw substrate. Cow dung and loamy soil, farm-yard manure, loamy soil and sand, and spent oyster mushroom substrates were used as casing materials to evaluate the yield and yield-contributing characteristics of C. indica. The results indicate that the number of effective fruiting bodies, the biological and economic yield, and the biological efficiency were statistically similar all of the casing materials used. The maximum biological efficiency was found in the cow dung and loamy soil casing material. The cow dung and loamy soil (3 cm thick) was the best casing material and the rice straw was the best substrate for the commercial cultivation of C. indica.

  • Raphiolepis indica (R. indica) is one of evergreen shrubs belonging to the Rosaceae and is grown wildly in Jeju. This study was performed to evaluate the hepatoprotective effect of different fractions (n-hexane, dichloromethane, ethyl acetate, butanol, water) from R. indica. Anti-oxidative effects were determined using 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging activity and total phenol contents. Hepatoprotective effect was identified by 3-[4, 5-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium bromide (MTT) assay in Huh7 cells. Among various fractions, ethyl acetate and butanol fractions showed the lowest DPPH remained rate reaching approximately 78.7 and 65.5% at $400{\mu}g/mL$. Ethyl acetate and butanol fractions showed the total phenolic content at 164.5 and 137.3 mg GAE/g extract. The ethyl acetate and butanol fractions were resistant against oxidative stress in MTT assay and showed higher hepatoprotective effect than other fractions. Therefore, these results suggest that the ethyl acetate and butanol fractions of R. indica might have therapeutic value in liver damage.

  • Opuntia ficus-indica has traditionally been used in prevention and treatment of various diseases such as diabetes mellitus. The current study was performed to determine whether Opuntia ficus-indica is associated with diabetes. Diabetic rat models were induced with streptozotocin (STZ). This study divided rats into 1 day (short-term) and 4 consecutive weeks (long-terms) of daily administration. These groups were subdivided into four groups each other for assessment of blood glucose level as follows: Group 1, untreated rats given distilled water; Group 2, untreated rats given Opuntia ficus-indica; Group 3, STZ-induced diabetic rats given distilled water; Group 4, STZ-induced diabetic rats given Opuntia ficus-indica. Blood glucose level was measured for one day and four weeks. In addition, serum markers of alanine aminotransferase (ALT), aspartate transaminase (AST), cholesterol, and creatinine were determined, and total protein triglycerides were measured at four weeks. Blood glucose level was highest in both groups (Group 3 and Group 4) at 30 minutes and two weeks and gradually decreased in a time-dependent manner. The difference in blood glucose among the four groups was significant (p < 0.05). Additionally, the levels of ALT, AST and triglycerides were significantly decreased by Opuntia ficus-indica.

  • The effects of air temperature on the grain filling stage of indica-japonica crosses were studied in artificial temperature-controlled cabinets, using Indica-Japonica crosses (Suweon 264, Suweon 258 and Milyang 29), Indica IR 36 and Lengkwang) and a Japonica rice (Jinheung). The optimum temperature to achieve maximum grain weight during the grain-filling stage was $26/18^{\circ}C$ for all varieties. Within the temperature range of 13 to $28^{\circ}C$, the grain filling period was shorter as the temperature was increased. At the highest temperature $(32/24^{\circ}C)$ the upper-position grains ("special spikelets") of IR 36 required 13days after flowering to reach the maximum weight, in Jinheung 23 days, in indica-japonica varieties (Suweon 264, Suweon 258, and MiIyang 29) 18 days, and in Lengkwang, 23 days. In the case of Lengkwang, at $32/24, \;29/21^{\circ}C$ and $26/18^{\circ}C$temperature range the upper-position grain also required same 23 days after flowering to reach the maximum weight. At the lowest temperature range of $17/9^{\circ}C$, Jinheung required 68 days and Lengkwang 53 days after flowering to reach maximum grain weight. The whole panicle took 10 to 15 days later than the special spikelets to reach the maximum weight. At lower-than-optimum temperature range $(l7/9^{\circ}C\;and\;20/12^{\circ}C)$, all IR 36 plant died within 15 days after flowering. In the case of indica-japonica varieties all plants died within 15 days only at $17/9^{\circ}C$. There were more chalky grains when the temperature was higher and lower than optimum. The highest and lowest temperature range produced dead rice (black and dark red rice). Lower than optimum temperature ranges $(17/9^{\circ}C\;and\;20/12^{\circ}C)$ affected grain quality (length, width and depth) at these temperature ranges, grains were shorter, narrower, and thinner than grains at the optimum temperature of $26/18^{\circ}C$. With regared and the effects of temperature on frequency of grain weight at grain filling stage of indica variety IR 36, the highest $(32/24^{\circ}C)$ and lowest $(23/15^{\circ}C)$ temperature ranges matched the frequency of grain weight curves. In Japonica variety Jinheung, at the three temperature ranges, that is, lowest $(17/9^{\circ}C)$ highest $(32/24^{\circ}C)$ and optimum $(26/18^{\circ}C)$, the frequency of grain weight curve showed very different patterns, In the case of indica-japonica variety Suweon 258, the frequency of grain weight curve was midway between that of IR 36 and Jinheung.

  • In this study, the extracts from the leaves of Rhaphiolepis indica(R. indica) and Quercus salicina(Q. salicina) confirmed antioxidative effects. The antioxidative and cytotoxic effects of the two extracts were analyzed according to varied concentrations and time. The extracts of R. indica and Q. salicina showed dose-dependent DPPH radical scavenging activities. The extracts of R. indica and Q. salicina at concentrations of 5 mg/mL showed DPPH radical scavenging activities at 89.93 and 92.41%. Therefore, Q. salicina were confirmed to have higher antioxidative effects than R. indica. Total phenolic contents were 65.20 mg GAE/g for R. indica and 85.20 mg GAE/g for Q. salicina. The result that Q. salicina have higher total phenolic contents than R. indica suggested a correlation between total phenolic contents and DPPH radical scavenging activity. The cell protective effects of HepG2 and A549 cells under oxidative stress, both the extracts showed relatively low cell protective effects at around 10%. The Cytotoxic effects of A549 Cells did not show cytotoxicity at concentrations of $100{\mu}g/mL$ or below. The results of this study are likely to be used as basic data to develop antioxidants using the extract of R. indica and Q. salicina.

  • Objectives: The aim is to identify any anti-tumor effects of Duchesnea indica(Andr.) Focke on colon cancer cells. Materials & Methods: Colo201 human adenocarcinoma cells were obtained from American Type Culture Collection. The boiled extract of Duchesnea indica(Andr.) Focke was added (10 and 20 microliters) to cultures and observed at 0, 6, and 12 hours, and at 12-hour intervals thereafter. Morphological changes in colon cancer cells were observed through an inverted microscope, Destruction of colon cancer cells was measured through Trypan blue exclusion testing. Suppression of the viability of colon cancer cells were measured via MTT assay. Anti-cancer mechanisms in the cell cycle of colon cancer cells were analysed via flow cytometry. Results: After introduction of Duchesnea indica(Andr.) Focke to cultures several changes were seen. Significant atrophy of the nucleus and cytoplasm of colon cancer cells was observed, indicating cell injury. Destruction of colon cancer cells was observed in direct proportion to dosage and duration. Suppression of viability of colon cancer cells for each test group was greater than that of the control group increasingly over time(36h, 48h, 60h, 72h), which was statistical significant (p<0.05). Cell numbers of the mitosis phase of the colon cancer cell cycle reduced. Conclusions: Statistcally significant anti-tumor effects of Duchesnea indica(Andr.) Focke were observed in this in vitro experiment. Results support a role for Duchesnea indica(Andr.) Focke in treatment of colon cancer. though it will required progressive research to develop a practical treatment.

  • The pigment extraction of Opuntia ficus-indica has been conducted to develop useful natural dyes in place of synthetic dyes which are suspected to bring serious environmental pollutions. The dyeing ability on wool fabric by addition of ascorbic acid and several mordants were investigated by means of color measurement. In addition, the fastness of washing, perspiration, rubbing, light, dry cleaning, effect on bacterial reduction and UV-B protection were also investigated. From these investigation, it is suggested that the pigment extracted from Opuntia ficus-indica can be used as a source of natural dyes and the obtained result are as follows. 1. Maximum absorption band (${\lambda}max$) of Opuntia ficus-indica extract is 533nm. 2. The wool fabric dyed with Opuntia ficus-indica extract has stable color by the addition of ascorbic acid and is achieved with addition of 0.1% ascorbic acid, 0.5% several mordant, and three repeated dying at $50^{\circ}C$ for 1.5hr. 3. The wash fastness of the dyed wool fabric when it is washed with neutral detergent is more effective than alkaline detergent. The dry cleaning fastness of the dyed wool fabric is more excellent. In addition, the perspiration fastness of the dyed wool fabric is increased by mordanting method. And than the rubbing fastness of the dyed wool fabric is showed excellent under dryness and wetness. Light fastness of the dyed wool fabric, however is showed inferiority. 4. The wool fabric dyed with Opuntia ficus-indica extract is showed effective bacterial reduction and UV-B protection is increased remarkably.

  • The dual effectiveness of Opuntia ficus indica extracts for browning inhibition and microbial inactivation on fresh-cut apples was investigated. Prepared apple slices were treated with 25, 50, 100, 200 mg/mL Opuntia ficus indica extracts, packaged in polyethylene bags, and stored for 10 days at 4, $21^{\circ}C$. Results indicate that Opuntia ficus indica extracts significantly (P < 0.05) inhibited the browning reaction of fresh-cut apples. This treatment also reduced peroxidase activities. The populations of Staphylococcus aureus significantly decreased with increasing extract concentration (p < 0.05). In particular, S. aureus was reduced to non-detectable levels after 2 days in 100 mg/mL treatment at $4^{\circ}C$ and $21^{\circ}C$. Opuntia ficus indica extracts therefore have antibacterial and antibrowning effects. The results suggest that Opuntia ficus indica extracts could be useful as a natural food preservative.
