  • The aim of this study is to investigate the effects of hot water soluble extract from Angelicae Radix on the components of serum and liver and the effects on the antioxidant system. For this purpose, five experimental groups were set up. And for fat source, perila oil enough with unsaturated fatty acid and beef tallow enough with saturated fatty acid were supplemented to the rats together with hot water soluble extract from Angelicae Radixs. Five experimental groups kept eight Sprague-Dawley rats respectively. They were CO group supplemented with basic diet of AIN-93, PO group supplemented with perila oil, POA group supplemented with perila oil and hot water soluble extract from Angelicae Radix, BT group supplemented with beef tallow, and BTA group supplemented with beef tallow and hot water soluble extract from Angelicae Radix. The results were; 1) Final weight, weight gain, fluid intake and FER were not different significantly among the experimental groups, 2) Significant difference of food intake was observed(p<0.05) in BTA group only, 3) No significant difference was observed in serum total lipid, serum triglyceride and HDL cholesterol among experimental groups. Serum total cholesterol and LDL cholesterol were significantly low(p<0.05) in the group supplemented with beef tallow which was with hot water soluble extract from Angelicae Radix (BTA group). 4)Liver total cholesterol in liver was low in groups supplemented with perila oil and hot water soluble extract from Angelicae Radix. In summary, hot water soluble extract from Angelicae Radix did not affect the weight gain, fluid intake and food efficiency ratio among the experimental groups, but had an effect of lowering food intake, serum total cholesterol and serum LDL cholesterol significantly in the groups which were supplemented with beef tallow and hot water soluble extract from Angelicae Radix. The effect of lowering liver total cholesterol with the supplementation of hot water soluble extract from AnRelicae Radix was observed in perila oil group only. The effect of lowering cholesterol with the supplementation of hot water soluble extract from Angelicae Radix was observed both in serum and in liver.

  • This study investigated the synergy effects of hot water soluble extract from Eleutherococcus senticosus and dietarty carnitine on the lipid metabolism and antioxidant defense system of rats on hypercholesterol diets. Sprague-Dawley male rats were fed either a hypercholesterol diet with water or a hot water soluble extract from Eleutherococcus senticosus and dietarty carnitine. The experimental groups consisted of the control group (CO), the group supplied with hot water soluble extract from Eleutherococcus senticosus(ES), and the group supplied with hot water soluble extract from Eleutherococcus senticosus and dietarty carnitine(ESC). Eleutherococcus senticosus was extracted, made into 0.5% solution, and fed to the ES and ESC groups. A 3% carnitine diet was supplied to the ESC group. Hypercholesterol diets contained 18% beef tallow and 5% cholesterol. After 4 weeks of administering these diets, serum and liver were obtained and the level of serum lipid and the activities of GOT and GPT were measured. In addition, the level of liver lipid and TBARS and the activity of GSH-Px were measured. The results were as follows: 1) Weight gain and FER in the group supplied with hot water soluble extract from Eleutherococcus senticosus and dietarty carnitine(ESC) was low significantly(P<0.05). 2) In the groups supplied with hot water soluble extract from Eleutherococcus senticosus(ES) and the group supplied with hot water soluble extract from Eleutherocorcus senticosus and dietarty carnitine(ESC), total serum cholesterol levels were both significantly low (P<0.05,P.0.01). 3) Serum GOT activity was significantly low(P<0.05) in the group supplied with hot water soluble extract from Eleutherococcus senticosus(ES) and in the group supplied with hot water soluble extract from Eleutherococcus senticosus and dietary carnitine(ESC). There was no difference between serum GPT activity in the control group and the groups supplied with hot water soluble extract from Eleutherococcus senticosus or dietary carnitine. 4) Liver triglyceride was low (P.0.05) in the group supplied with hot water soluble extract from Eleutherococcus senticosus and dietarty carnitine(ESC). No difference was observed in other lipid composition, TBARS level, and GSH-px activity in liver between the control group and the experimental groups. In summary, the effects of hot water soluble extract from Eleutherococcus senticosus and dietarty carnitine on the lipid metabolism and antioxidant defense system (such as weight gain, FER, total serum cholesterol and liver triglyceride) were low when Eleutherococcus senticosus and dietarty carnitine were supplied simultaneously.

  • To investigate the effects of hot water soluble extract from Angelicae Gigantis Radix on lipid metabolism and antioxidant defense system in rats fed hypercholesterol diet, Sprague-Dawley male rats were fed either hypercholesterol diet with water or hot water soluble extract from Angelicae Gigantis Radix. Hypercholesterol diet contained 18 % beeftallow and 5 % cholesterol. After 4 weeks of experimental periods serum and liver obtained. The level of serum lipid and the activities of GOT and GPT was measured. The level of lipid and TBARS and the activity of GSH-Px was measured also. The results obtained were: 1) Food intake in the experimental group supplied hot water soluble extract from Angelicae Gigantis Radix was low significantly. 2) In the experimental group supplied hot water soluble extract from Angelicae Gigantis Radix of serum total lipid and total cholesterol was significantly low. 3) Serum GOT activity was significantly low in the experimental group supplied hotwater soluble extract from Angelicae Gigantis Radix. There was no difference of serum GPT activity between control and experimental group supplied hot water soluble extract from angelical Gigantis Radix. 4) There was no difference of lipid composition, TBARS level and GSH-px activity in liver between control and experimental group. The result of this study indicates that the hot water soluble extract from Angelicae Gigantis Radix was effective in decreasing the food intake of the experimental animals in the hypercholesterol diet and also effective in decreasing the levels of serum total lipid, total cholesterol and GOT activity. However it was not effective to change the level of lipid, TBARS and GSH-Px activity of liver.

  • Recently, due to environmental and toxicity issues, there has been increasing attention on research regarding natural products that can reduce the use of chemical fertilizers. Wood extracts derived from the biorefining process contain various fertilizer ingredients. HPLC analysis revealed that wood extract contains approximately 5.2% hemicellulosic sugar. The growth of lettuce (Lactuca sativa) upon treatment with wood extract (extract obtained from steam-exploded pine) or water-soluble fertilizers containing different nutrients was analyzed in this study. After two weeks, the growth characteristics of lettuce as affected by wood extract or water-soluble fertilizers were significantly different. The effect of water-soluble fertilizers containing ascorbic acid, magnesium sulfate, citric acid, potassium nitrate, amino acids, or seaweed extract was less desirable than that of wood extracts regarding plant height (18.6 cm), number of leaves (10), leaf length (14.1 cm), shoot fresh wight (9.8 g/plant), root fresh weight (0.8 g/plant) and shoot dry weight (0.6 g/plant). The plant height, number of leaves, leaf length, shoot fresh wight, root fresh weight, shoot dry weight of water-soluble fertilizers containing wood extract were significantly different compared to the control (plant height :13.5 cm, number of leaves : 7, leaf length : 9.4 cm, shoot fresh wight : 5.3 g/plant, root fresh weight : 0.7 g/plant, shoot dry weight : 0.4 g/plant, root dry weight : 0.07 g/plant). From these results, it was concluded that wood extract can be used as a potential water-soluble fertilizer to increase the yield of leafy vegetables.

  • Against the mutagen MNNG and NOPD with SOS chromotest, the antigenotoxic activity of MeOH-soluble extract was much more effective than that of the water-soluble one. When the extract was added to the certain concentration, the antigenotoxic acivity was enhanced. Against the mutagen NOPD with Ames test, the antimutagenic activity of MeOH-soluble extract was better than that of the water-soluble one. The 60.4% of the inhibition ratio for the revertant colony-forming unit was shown at 5 mg of MeOH-soluble extract per plate. Antimutagenecity test with SOS chromotest and Ames test were performed using water-soluble and MeOH-soluble extracts from of Gleditsia sinensis. The antioxidant activity of MeOH-soluble extract with the NBT method was higher than that of the water-soluble one.

  • Objectives : Methicillin-resistant Staphylococcus aureus (MRSA) CCARM 3251 and S. aureusKCTC 1928 have been known to be resistant to many kinds of antibiotics. The extract of Glycyrrhizae Radix showed antibacterial activity against MRSA and antibiotics-resistant S. aureus. Methods : We examined the effects of the water-soluble extract and the methanol-soluble extract of Glycyrrhizae Radix on MRSA and antibiotic-resistant S. aureus. The methanolic extract was further fractionated with organic solvents such as hexane, chloroform, and ethyl acetate in that order. Results and Conclusions : The methanol-soluble extract of Glycyrrhizae Radix showed relatively high antibacterial activity against MRSA and antibiotic-resistant S. aureus. However, the water-soluble extract of Glycyrrhizae Radix showed no antibacterial activity against MRSA and antibiotic-resistant S. aureus. Among the fractions tested, the chloroform fraction showed the highest antibacterial activity against MRSA and antibiotic-resistant S. aureus. The methanol-soluble extract of Glycyrrhizae Radix minimal inhibitory concentrations (MICs) against MRSA and antibiotics-resistant S. aureus were $5{\;}mg/m{\ell}$ in both. The methanol-soluble extract of Glycyrrhizae Radix was separated using thin-layer chromatography and detected with UV -detector. Further study should be carried out to identify which effects cell growth inhibition of MRSA and antibiotics-resistant S. aureus.

  • We evaluated the biological activities of five water extracts of tissue of the mottled anemone Urticina crassicornis. Most extracts exhibited broad-spectrum antimicrobial activity as determined by ultrasensitive radial diffusion assay (URDA) against gram-positive and -negative bacteria, including a fish pathogen, Aeromonas hydrophila, but no activity against fungi. The activity of the extracts was abolished by tryptic digestion, indicating that protein compounds were responsible for the antimicrobial activity. Furthermore, in a 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical-scavenging activity assay, only the visceral tissue extract showed activity. However, no extract had hemolytic activity against human red blood cells. Consequently, this study suggests the water-soluble extract of mottled anemone to be a promising source of proteinaceous antimicrobial compounds that can be utilized for development of novel antibiotics.

  • Antigenotoxicity test (SOS chromotest), antimutagenecity test (Ames test), and antioxidant test (NBT method and xanthine-xanthine oxidase method) were carried out using water-soluble and methanolic extracts from Puerariae Flos. Against the mutagens MNNG and NQO, antigenotoxic activity of methanolic extracts were much more effective than that of water-soluble ones. When the methanolic extract was added to the certain concentration $(100{\mu}{\ell}/tube)$, antigenotoxic acivity against the mutagen MNNG was enhanced. Contrary to the water-soluble extract, the methanolic extract showed high antigenotoxicity against the mutagen NQO with increment of the extract. Against the mutagen MNNG with Ames test, antimutagenic activity of the methanolic extract at $300{\mu}{\ell}/tube$ was 96% as an inhibition ratio of revertant forming CFU/plate. The antioxidant activity of water-soluble extract was comparatively higher than that of the methanolic one.

  • This study is to find out effects of hot water soluble extract from green tea, one of the Korean favorites, on the calcium metabolism and bone strength in body. To do so, calcium, phosphate, creatinine concentration and ALP activity in blood and the content of calcium and ash in the organ, the length, weight, strength in bone were measured. In addition, to find the calcium metabolism, the level of calcium intake, excretion, retention were measured. Twenty male Sprague-Dawley rats were divided into two groups and isoloated soy protein was provided as the source of protein and CaCO₃ was provided as the source of calcium. 0.5% hot water soluble extract from green tea was provided to the green tea groups and for the control group deionized water was provided. The results are as follows ; 1. There is no difference between the experimental groups in diet intake, weight gain, and the feed intake. 2. Feed efficiency ratio was low in the group which hot water soluble extract from green tea was provided. 3. There is no difference between groups the level of calcium, phosphorus, creatinine and ALP activity in serum. 4. There is no difference between groups weight, contents of ash and calcium in kidney and liver. 5. There is no difference between groups in calcium intake, absorption, excretion, and retention. 6. There is no difference between groups weight, length and strength in bone. In summary, when hot water soluble extract from green tea was provided with the amount of 150-200mg, which is taken when people generally drink as favorite tea, weight gain was reduced due to the decrease of feed efficiency ratio. However, it did not affect the availability of calcium in body at all. Thus, even if a big quantity of green tea powder or solid of hot green tea extract is not provided, the quantity obtained when people drink green tea lowers the feed efficiency ratio without reducing availability of calcium in body.
