Salicylate from plant foods and histamine from animal foods have been suggested to cause various food allergic symptoms. Salicylate regarded as one of the inducing agents f3r chronic urticaria and asthma in allergic patients was studied. There is much interest about the effects of salicylate in food allergy. It it recently suggested that the intake of salicylate from foods may have contributed to chronic urticaria and asthma. The purpose of this study is to analyze the salicylate content in various foods. 153 ingredients commonly used in Korean foods were analyzed by HPLC. Among the vegetables, chard(8.22$\mu\textrm{g}$/g), soybean sprout(5.13$\mu\textrm{g}$/g), perilla lean3.03$\mu\textrm{g}$/g), Chinese cabbage(2.25$\mu\textrm{g}$/g), carrot(2.16$\mu\textrm{g}$/g), and squash(1.33$\mu\textrm{g}$/g) con-rained higher amounts of salicylate as compared to other vegetables. Among fruits, oranges(5.13$\mu\textrm{g}$/g), grapefruits(2.90$\mu\textrm{g}$/g), and plums(1.65$\mu\textrm{g}$/g) contained the most. In animal foods, almost no salicylate was found except in chocolate milk(0.32$\mu\textrm{g}$/g). It was also found in black pepper(8.2$\mu\textrm{g}$/g), coffee(can)(5.00$\mu\textrm{g}$/g), mustard(4.16$\mu\textrm{g}$/g), curry powder(3.24$\mu\textrm{g}$/g), kochujang(2.37$\mu\textrm{g}$/g), cream powder(1.19$\mu\textrm{g}$/g), brown rice(1.04$\mu\textrm{g}$/g) and sesame oil(1.00$\mu\textrm{g}$/g). All information found in this study can be used as nutritional education materials in potentially allergic people for a prudent diet plan and can also provide proper dietary guidelines for these allergic patients.

This study was undertaken to evaluate the gastrotherapeutic effects of the extract of Rosa rugosa. It can be regarded that the antigastric and anti-ulcerative effect of Rosa rugosa is originated from the reduction of total acid output identified by gastric secretion test. To clarify the protective mechanism of the Rosa rugosa extract, the gastropathy was induced in rats with alcohol-salicylate and the activities of the free radical scavenging enzymes were examined. The acitivity of superoxide dismutase and glutathione peroxide were significantly increased and the total content of glutathione was recovered. We concluded that the protective effect of the extract of Rosa rugosa on gastropathy in rats is its ability increased the activities of the free radical scavenging enzymes.

Garlic has been known to be effective against the gastrointestinal diseases which can be induced by production of oxygen-derived free radical. It has been shown that bamboo salt is effective on the treatment and prevention of various gastrointestinal disorders. Bamboo salt is a processed salt invented by a Korean, ll-Hoon Kim. It has been reported that garlic and bamboo-salt are useful to the treatment of gastric disorders in Korea. To clarify the protective mechanism of the garlic-bamboo salt mixture, the gas-tropathy was induced in rats with alcohol-salicylate and the activities of the free radical scavenging enzymes were examined. In this study, we found that the garlic-bamboo salt mixture reduced the severity of hemorrhagic lesion in gastric mucosa in the rats. In addition, the activities of superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione reductase (GR) were significnatly increased and the total content of GSH was recovered. From those results, we concluded that the protective effect of the garlic-bamboo salt mixture on gastropathy in rats is its ability to recover the level of GSH and to increase the activities of the free radical scavenging enzymes (SOD, GPx, GR).

This experiment was conducted to find out suitable extraction time of available fragrant component in Lilium Oriental Hybrida 'Casa Blanca' based on qualitative and quantitative variation of its fragrant component in its flowering stages. The content of essential oil in its flowering stages increased with the progress of flowering stages except flower bud stage and it had the most oil content in its stage after full bloom. The analysis of the essential oil in Lilium Oriental Hybrida 'Casa Blanca' in its flowering stages shows that its main constituents were farnesol (18.96%), benzyl salicylate (13.81%), butyl-hydroxy toluene (12.87%), geranyl linalool isomer (7.46%), isoeugenol (7.17%) in its each stage. Benzenoids had much content at half bloom stage and full bloom stage while fatty acid derivatives had much content at initial flowering stage and after flowering stage. Most benzenoids such as butyl-hydroxy toluene and isoeugenol, which are some of main constituents of Lilium Oriental Hybrida 'Casa Blanca' had strong antioxidant effect. So they were expected to be used as antioxidant agents for food, feed, vegetable oil. The content of monoterpene compounds like geranyl linalool isomer increased at its later stage. Sesquiterpene such as farnesol, which is main component of lily existed only at full bloom stage. Therefore farnesol and geranyl linalool isomer of Lilium Oriental Hybrida 'Casa Blanca' are expected to be used for important spices with good fragrance. The suitable extraction time for the usable main constituents of Lilium Oriental Hybrida 'Casa Blanca' is as follows; farnesol and benzyl salicylate: at full bloom stage, butyl-hydroxy toluene: at half bloom stage, geranyl linalool isomer and isoeugenol: at stage after full bloom. Finally there was variation in essential oil components and contents of Lilium Oriental Hybrida 'Casa Blanca' in its flowering stages and they are expected to be used usefully for flavor industry, food industry, aromatherapy, when they are extracted at their suitable extraction time.

A bacterium which degrades efficiently synthetic detergents was isolated from the polluted waters, activated sludge of wastewater treatment plants or polluted soil. This bacterium showed considerably higher growth rate in the agar plate containing $2,000{\mu}g/ml$ of synthetic detergents than any other isolated strains, was identified as a Pseudomonas fluorescens or strains similar to it. The strain was named as a Pseudomonas fluorescens S1. Optimum pH and temperature for the growth of the Pseudomonas fluorescens S1 were pH 7.0 and $30^{\circ}C$, respectively. The strain was resistant to streptomycin and gentamycin, but sensitive to kanamycin. The strain was greatly resistant to zinc chloride, lead nitrate and copper sulfate, but unable to grow in the presence of relatively low concentrations of mercury chloride and silver nitrate. This strain utilized benzene, catechol, cyclohexane and xylene as a sole carbon source. The strain was well grown in the medium containing ABS 10,000${\mu}g$/ml. Degradation of ABS was 55% and 60% at 20${\mu}g$/ml and 100${\mu}g$/ml of ABS, respectively. Benzene ring was degraded 45% in 100${\mu}g$/ml of ABS. During the incubation of the strain in the medium containing ABS 100${\mu}g$/ml and COD 10,000${\mu}g$/ml for 4 days, degradation of ABS and COD were reduced to 40${\mu}g$/ml and 3,200${\mu}g$/ml, respectively. Total amino acid content of the Pseudomonas fluorescens S1 grown with 1,000${\mu}g$/ml of ABS was 115mg/g cell, whereas its content was decreased in the bacterium grown without synthetic detergent by 9.4%.
