One of the possible mechanisms of multi-drug resistance found in cancer cells is the over-expression of P-glycoprotein (P-gp). Studies have shown that compounds found in plants including vegetables and fruits not only have anticancer activities but may also modulate P-gp activity. The effect of flavonoids and organic isothiocyanates on P-gp activity was studied in human uterine sarcoma cell lines, MES-Sa (sensitive) and MES-SD/DX5 (resistant). The accumulation of daunomycin (DNM), a P-gp substrate, was approximately 10 times greater in the sensitive cell as compared to the resistant cells over the entire time course (up to 2 hrs).

The purpose of this study was to investigate basic data on the degree of parents' recognition and satisfaction with the use of environment-friendly agricultural products. The conclusions of this study are as follows. The survey on the use of environment-friendly products in households showed that 68.7% of the respondents used environment-friendly products at home. The frequency of purchasing organic products by household consumers showed that 25.1% of the respondents bought organic products one to two times per week. The most popular items of the environment-friendly agricultural products used were vegetables, comprising 63.9%. The households with more than 3,000,000 won of monthly income tended to consume more domestic livestock products (p < 0.05). In comparison to general agricultural products, environment-friendly agricultural products users showed higher satisfaction level with a better quality in term of safety, quality, nutrition, taste, appearance, diversity and price. The degree of satisfaction with safety was the highest ($3.8{\pm}0.68$), and price showed the lowest ($2.76{\pm}0.79$). The degree of parents' recognition of the governmental support for environment-friendly agricultural products showed that those who were aware of the supporting policy were 44.5%, but 55.5% of them didn't know about the fact that 46.6% of the respondents agreed that environment-friendly agricultural products should be used in more than 50% of the foods used for school food service. The respondents pointed out that vegetables (45%) sprayed with pesticide are the most urgent food item that need to be replaced by environment-friendly farm products.

Pectobacterium carotovorum subsp. carotovorum was found to be highly virulent to various vegetables, including Chinese cabbage. The antibacterial isolate CAB12243-2 was tested in a field bioassay for suppressing soft rot disease. The nucleotide sequencing of the 16S rRNA gene identified, the CAB12243-2 strain used in this study as Bacillus toyonensis. B. toyonensis CAB12243-2 inhibited the pectate lyase process by soft rot pathogens, and used trehalose and glucose as carbon sources. In field tests, the antibacterial isolate B. toyonensis CAB12243-2 suppressed soft rot disease with 73.0% control efficacy on the spring cultivar "Norangbom" and with 68.9% efficacy on the fall cultivar "Bulam 3". These results suggest that B. toyonensis CAB12243-2 can be used as a biological control agent for the control of soft rot diseases on vegetables.

A questionare survey was performed to investigate the citizen's attitude toward garbage composting and compost. Most people considered that the food waste treatment problem is serious and 91.1% of people know that it is possible to make compost out of food waste. Also, people think that compost made from food waste is better than the compost made from manures. People favor vegetables grown by organic compost than those grown by chemical fertilizer and was willing to pay 10~20% more prize. Most people was willing to cooperate in source separation for garbage composting and throught that the most desirable treatment method for garbage would be composting.

To investigate the perception and consumption of imported and organic produce, a survey was conducted using a questionnaire in Seoul, Taejon and Cheongju from February to March in 1995. The responses of 350 housewives were analyzed. Most of the subjects (96.8%) know an increase of imported produce, and 86.3% thought that imported produce was not safe. Ninety-two percent of the subjects preferred domestic produce to imported produce. The reasons were for the support of domestic farming (36.7%), hazardous chemicals in imported produce (25.0%), good taste (24.1%) and high quality of domestic produce (13.1%). Seventy-eight percent of the subjects had purchased imported produce. The reasons for purchase were cheap price (67.7%), high quality (16.2%), and good taste (5.4%). Imported produce were purchased in the following order ; fruits such as banana, kiwi, orange and grapefruit, seasonings such as garlic and sesame, vegetables such as onion, braken and green onion, and beans and grains such as soybean, red bean, and barley. Most of the subjects (94.3%) had been informed on organic produce. Among these, 45.2% obtained the information by TV or radio. However, son for purchase was low residual chemicals (64.6%). The reasons against purchase were inconvenience of purchase (42.3%), high price (25.4%), and disbelief of low residual chemicals (19.7%). Therefore, domestic produce should be good in quality and taste, and be safe without residual chemicals in order to compete with imported produce with cheap price. Informations on organic and imported produce should be provided to consumers, and the distribution system of organic produce should be improved for consumers convenience.

This study was conducted to examine the levels of total and organic mercury in the scalp hair of the elementary school children and adults, and their relationship with the consumption pattern of fishes and shellfishes. The scalp hair samples were collected from the occipital part of 115 children and 131 adults in costal, urban and rural areas of Kyungpook province from June to August 1991. The mercury content was analysed by the atomic absorption spectrophotometer (model IL. 555) with atomic vapor accessory (model IL. 440). The total and organic mercury contents of hair were significantly higher (p<0.01) among the children who prefer fish and/or shellfish (7.728 ppm, 6.610 ppm), and canned fish and/or fish pastes (6.969 ppm, 5.885 ppm) than those who prefer meat (4.822 ppm, 3.905 ppm) and vegetables (3.974 ppm, 3.224 ppm). The children who prefer to eat the canned fish without cooking showed a higher mercury content than the children who prefer to eat it as stew or mixed with vegetables (p<0.01). There was a dose-response relationship between the intake frequency of canned fish, raw fish and cooked fish and the content of total and organic mercury of hair, the children who eat fish almost everyday showed 2 times higher than those who eat rarely (p<0.01). The mercury content in the hair of the children who eat raw fish was significantly higher than that of the children who eat boiled or broiled fish (p<0.01). The total and organic mercury contents of adult scalp hair increased with age up to the forties and slightly decreased in the fifties. The mercury contents of those who were engaged in the fishery and raw fish restaurant were 2 times higher than those of the farmers. The mercury content of the persons who were favorite dishes of fish and shellfish were most high, and who prefer raw fish were 2 times higher than those of the persons who prefer vegetables and broiled fish. The contents of total and organic mercury in adult scalp hair showed also a increasing tendency with the intake frequency of raw and cooked fish.

Soil trace elements and their bioaccumulation in agricultural products have attracted widespread concerns, yet the crop uptake characteristics of trace elements in different soil-plants systems have been rarely investigated. Experiments were carried out to investigate the effect of soil properties on trace element concentrations in cabbage and radish. Soil pH and total organic matter were major factors influencing trace elements transfer from soil to vegetables. Inclusion of other soil properties in the stepwise regression analysis improved the regression models for predicting trace element concentrations. Consideration of other soil properties should be taken into account for more precise prediction of trace element concentrations in the two vegetables, which could help quantitatively evaluate the ecologic risk of toxic trace elements accumulation in crops.

Soil residues in a tobacco field yearly treated with a soil insecticide, Heptachlor, was analyzed by GLC equipped with electron capture detector(ECD). In addition, translocation of the heptachlor residues into two staple vegetables, radish and chinese cabbage was also studied under field conditions. The results were summarized as follows; 1. The Heptachlor residues in the soil of tobacco plots were less than 0.010 ppm. 2. The Heptachlor residues in radish and chinese cabbages cultivated in the tobacco plot were also below 0.010 ppm. 3. Amount of Heptachlor residues translocated into the vegetables were not related to the concentrations of the residues in the soil.
