  • Chinese cabbage is a vegetable of Cruciferous family. It was usually consumed as Kimchi. It was known to have amount of vitamin c. Recently the trend for the development of functional food combined with oriental herbs. For this aim the study was performed to evaluate the hepatoprotective effect via antioxidant activity of leaf and root of Sanchon Chinese cabbage(Brassica campetris L.) comparatively. The methanol extracts of Chinese cabbage were tested for investigating the effects on the formation of lipid peroxide and the activities of free radical generating enzyme in vitro in bromobenzene-treated rats. The methanol extracts of chinese cabbage reduced bromobenzene-induced hepatic lipid peroxidation and inhibited the activity of xanthine oxidase. The methanol extracts of chinese cabbage did not activate amionopyrine N-demethylase, aniline hydroxylase and glutathione S-transferase. Epoxide hydrolase activity was decreased by bromobenzene, which was restored by pretreatment of the methanol extracts of chinese cabbage. The results suggest that the methanol extracts of Chinese cabbage is reduced by enhancing the activity of epoxide hydrolase.

  • The genomes of Chinese native chicken populations were screened using microsatellites as molecular markers. A total of, 528 individuals comprisede12 Chinese native chicken populations were typed for 7 microsatellite markers covering 5 linkage groups and genetic variations and genetic distances were also determined. In the 7 microsatellite loci, the number of alleles ranged from 2 to 7 per locus and the mean number of alleles was 4.6 per locus. By using fuzzy cluster, 12 Chinese native chicken populations were divided into three clusters. The first cluster comprised Taihe Silkies, Henan Game Chicken, Langshan Chicken, Dagu Chicken, Xiaoshan Chicken, Beijing Fatty Chicken and Luyuan Chicken. The second cluster included Chahua Chicken, Tibetan Chicken, Xianju Chicken and Baier Chicken. Gushi Chicken formed a separate cluster and demonstrated a long distance when comparing with other chicken populations.

  • To investigate the genetic diversity of seven Chinese indigenous meat goat breeds (Tibet goat, Guizhou white goat, Shannan white goat, Yichang white goat, Matou goat, Changjiangsanjiaozhou white goat and Anhui white goat), explain their genetic relationship and assess their integrity and degree of admixture, 302 individuals from these breeds and 42 Boer goats introduced from Africa as reference samples were genotyped for 11 microsatellite markers. Results indicated that the genetic diversity of Chinese indigenous meat goats was rich. The mean heterozygosity and the mean allelic richness (AR) for the 8 goat breeds varied from 0.697 to 0.738 and 6.21 to 7.35, respectively. Structure analysis showed that Tibet goat breed was genetically distinct and was the first to separate and the other Chinese goats were then divided into two sub-clusters: Shannan white goat and Yichang white goat in one cluster; and Guizhou white goat, Matou goat, Changjiangsanjiaozhou white goat and Anhui white goat in the other cluster. This grouping pattern was further supported by clustering analysis and Principal component analysis. These results may provide a scientific basis for the characteristization, conservation and utilization of Chinese meat goats.

  • The purpose of this study was to compare and analyze the assessment of salty taste and high-salt dietary behaviors of Korean university students and their Chinese counterparts. The researchers developed a taste assessment computer program focusing on preference for salty taste, and it was applied to 300 university students, including 100 Korean students, and 100 Chinese students in Daegu of South Korea, and 100 Chinese students in Shenyang of China (144 males and 156 females). The results of the taste assessment of Chinese and Korean university students are as follows. Among males, Koreans (36.0%), Chinese students in Korea (36.2%), and Chinese (40.4%) scored highest in the "a bit salty" followed by "normal." Among females, Koreans (36.0%), Chinese students in Korea (49.1%), and Chinese (28.3%) scored highest in the "normal". In terms of salt concentration in solution, among the male subjects, most Koreans favored the salt concentration of 0.31%, which is considered to be a "normal" concentration; most Chinese students in Korea favored 0.63%, which is considered to be "a bit salty", and most Chinese favored the concentration of 1.25%, which is considered to be "salty". As for the female subjects, Koreans, Chinese students studying abroad, and Chinese favored 0.31%, the "normal" level of concentration. Korean students scored higher than Chinese students in Korea and Chinese students both in males and females (p < 0.001, p < 0.01), in terms of high-salt dietary behaviors favored salty taste. This study suggests that Chinese university students need nutrition education in terms of modifying eating behaviors to reduce dietary salt intake.

  • The study was conducted to investigate the dietary behaviors and lifestyles of Korean university students and Chinese international students in the Jeonbuk area. Self-administered questionnaires were collected from 241 Korean university students and 198 Chinese international students. Statistical data analysis was completed using SPSS v. 12.0. Breakfast-skipping among subjects was very common, and the most frequently given reason for skipping this meal was 'lack of time'. More than 85% of Korean male students and 75% of Korean female students reported regularly eating lunch in university canteens or restaurants around campus, whereas 86% of Chinese male students and 82% of Chinese female students regularly ate their lunches in university canteens or at home. About 62% of Korean male students, 72% of Korean female students, 48% of Chinese male students, and 70% of Chinese female students responded that they do not regularly eat dinner, the main reasons cited for this being 'irregularity of lifestyle' and 'part-time work'. Snack intake by the subjects was high. Beverages were the snack item most frequently consumed by Korean and Chinese male students, whereas cookies and fruits were most frequently consumed by Korean and Chinese female students. About 28% of Korean male students and 44% of Chinese male students were smokers, respectively. Half of Chinese female students drank alcohol once or twice a week. About 42% of Korean male students and 65% of Chinese male students played sports, respectively. Dietary behaviors and lifestyles of Korean and Chinese students tended to be very similar. Chinese students performed more health-oriented activities in comparison to Korean students. In conclusion, a practical and foreigner-friendly nutritional education program should be devised in order to correct the dietary behaviors and health-related lifestyles of Korean and Chinese students.

  • The genetic diversities of 10 Chinese pig populations were analyzed by using microsatellite DNA polymorphisms. The results showed that the mean heterozygosities of the 10 populations were between 0.4561 and 0.6446, the mean polymorphism information contents were 0.4241-0.6184 and the mean effective number of alleles were 2.4295-3.7573. These indicated that the genetic diversity of local Chinese pigs was high. The clustering of the 10 populations was nearly inaccordance with their geographical distributions.

  • The starch properties of two chinese yams were evaluated in this study. Amylose content ranged 13.5% to 19.3%. The swelling power of starches varied 10.98% to 11.43%. Water binding capacity in chinese yam starches ranged 93.46% to 107.21%, high WBC was observed in Ma 1. The onset temperature (To) of two chinese yam starches ranged 62.9 to $75.0^{\circ}C$, peak temperature (Tp) ranged 76.2 to $84.7^{\circ}C$. The PHI(peak height index) was about 4-fold higher in Anwon cultivar than in Ma 1 cultivar. SEM revealed that starches has a presence of large oval or spherical to small irregular-shape granules. Starch granule size ranged 15.23 to 15.52 ${\mu}m$, showing a typical C-type X-ray pattern.

  • The purpose of this study was to clarify the impact of national and corporate brand image of Korea on chinese consumers' purchasing Intention, also the impact of China on korean consumers' purchasing Intention. And the second aim of the research is to provide Korean businessmen who are interested in chinese market with information about chinese consumers' purchasing behaviour. Data from 205 chinese and korean consumers were analysed. As the result of analyses, it was found that Korean country image positive affects corporate brand image(samsung) and Chinese country image negative affects corporate brand image(haier) and product image. Korean corporate brand image only affects product image on chinese consumers. The product image affects Korean and Chinese consumer's purchasing intention.
