  • This study was carried out to elucidate the effect of different rearing system on cortisol level, stress hormone, and fatty acid composition in the edible muscle tissues. These steers were reared in two different systems including antibiotic-free (ARS) and conservative system (CRS). In the M-Longissimus tissue, cortisol level was significantly lower in ARS than CRS, (p=0.0176). But, the levels of total saturated and unsaturated-fatty acids does not differ in ARS as CRS (p >0.05). However, the total saturated fatty acid levels tended to be greater in CRS and the total unsaturated fatty acid levels tended to be greater in ARS. However, the level of n-6 unsaturated fatty acid was higher in ARS than CRS (p=0.004). Especially, levels of linoleic acid (LA) and ${\gamma}$-linolenic acid (GLA) were significantly higher in ARS (p <0.01). Cortisol level and the n-6 fatty acid content in muscle tissue were negatively correlated (at p=0.00140.) In conclusion, ARS may produce beef with higher quality which contains lower cortisol and greater n-6 fatty acids, such as ALA and GLA.

  • Three different diet were made with meat for Crossbred pig ($^{\circ}_{+}$, 195 days old, $l15{\pm}5\;kg,\;Landrace{\times}Yorkshire{\times}Duroc$) and used as feed for rats after transformed into 12% protein, These diets include a pork not fed with tangerine peel during finishing period (Control, $T_0$), a pork fed with 3 and 5% tangerine peel during growing and finishing period, respectively ($T_1$), and a pork fed with 6 and 10% tangerine peel during growing and finishing period respectively($T_2$). The effects of the diet on physiological activities of rats were studied by feeding 17 weeks-old Sprague-Dawley rats with the three diets for 4 weeks. The feed intake, weight gain, feed efficiency ratio, and weight of liver, kidney, spleen and epididymal fat pad for the rats was similar among the diets. The total lipid level of liver was similar among $T_0,\;T_1\;and\;T_2$. However, it was found that $T_1\;and\;T_2$ had significantly lower triglyceride and cholesterol level than $T_0$(p<0.05). All the diet groups showed similar trends in terms of the serum total lipid, phospholipid, triglyceride, total cholesterol, HDL-cholesterol and LDL-cholesterol level, and atherogenic index, hemoglobin level, and ${\gamma}-GTP$, ALT, AST and ALP activities.

  • This study aims at providing exercisable basic data for the management of protection areas in China by investigating into their legal system such as current laws, regulations, other relevant laws and international treaties and the management system such as history, classification, organization, personnel, funds and main management work.. In People's Republic of China (1954), several laws have been enacted in succession, such as Environment Law (1989), Regulations of Natural Reserves (1994) and Land Management Methods of Natural Reserves (1995). The development process of China's natural reserves is divided into the following five phases. In the initial phase (1956-1965), about 20 natural reserves were established; in the lag phase (1966-1978), a part of the natural reserves was destroyed under the influence of the Great Cultural Revolution; in the development phase (1979-1998), a normative legal system began to appear after the reform and opening up; in the leap phase (1999-2006), the number of natural reserves increased dramatically; in the stable phase ( 2007-present), the protection and restoration of the ecological environment have been implemented, and the supervision and management have been strengthened. China has established natural reserves of national, provincial, municipal and county levels according to the relevant laws. According to the resource categories, natural reserves can be divided into natural ecosystem reserves, wildlife reserves and natural relic reserves. The Ministry of Forestry is in charge of 1,958 natural reserves which account for 74.2 % of the total natural reserves in China. In China, there are 1,384 natural reserves (52.4 %) for which management institutions have been set up. 1,702 natural reserves (64.47 %) are equipped with management staff, showing a higher ratio than the natural reserves which have set up management institutions.

  • To prepare useful foods from Acanthopanax koreanum, extraction of major constituents by water and ethanol solutions were investigated Reflux extractions of 300 g of dried material of particle size less than 0.5 cm, were carried out in 7.5 L of water, or ethanol solutions (30 -95% v/v) for 9 hr at $100^{\circ}C$. The pH values of extracted solutions were 4.0-6.5. The Color b-value of extracted solutions increased as ethanol concentrations dropped and with longer extraction times. The amounts of material in extracts increased rapidly in the first 2-3 hr of extraction. The extract levels from 30-70% ethanol solutions were 0.27-0.47 g/100 g. The main free sugars of extract were sucrose, fructose and glucose. Eleutherosides were extracted rapidly (within 3 hr), and eleutheroside extraction was best in water or in 30-70% ethanol 95% ethanol solutions were less effective. The eleutherosides were extracted to 97% by water or 30-70% ethanol solutions after 3-5 hr. Acanthoic acid extraction was more affected by ethanol level than by extraction time water achieved only trace extinction. In summary, reflux extraction in 40-70% ethanol for 3-5 hr was adequate for the extraction of functional materials from Acanthopanax koreanum.

  • This study was conducted to establish technologies for plug seedling production using somatic embryos-derived regenerants and their seeds in Bupleurum falcatum L. Among distilled water, GA (0.1mg/l) and putrescine (0.lmg/l) treated to regenerants for acclimatization, GA was most effective to develop shoots and roots, 1/2X MS medium and NAA 0.1mg/l + BA 0. 5mg/l enhanced the growth rates of the regenerants and increased dry weight. Activated charcoal effected to grow markedly leaves and roots of the regenerants at the level of 0.4 %. Regenerants increased their plant height, root length and dry weight at $30^{\circ}C$. Plug seedlings originated from seeds of the tissue culture regenerants showed the maxium growth on the mixture of peatmoss soil (2) and mountain sand (1) .Root length, leaf area and dry weight of plug seedlings increased significantly when No.1, 2 and 3 of Wondergrow solution were mixed in the ratio of 1.3 - 0.9 - 0.1. Light supplement (4%) and high tem­perature $(30^{\circ}C)$ promoted the growth of plug seedlings as well as dry weight. Ninety days seedlings were more vigorous and adaptable for transplanting than other seedlings.

  • This study is a study on how to revitalize social and economic organizations in the Chungnam region. For this, the following major results were presented in literature studies based on prior studies. First, it is necessary to upgrade the social economic organization promotion system and system in Chungnam. Second, there is a need to advance the measures to revitalize various social and economic organizations in cities and counties by building an integrated support system for social and economic organizations. Third, it is necessary to expand the public purchase of products of social economic organizations. Fourth, it is necessary to strengthen the business competency of the social economy organization and promote education. Fifth, it is necessary to upgrade the network for social economic organizations and create differentiated businesses. On the other hand, the social economic organization in Chungnam region shown through this study is as follows. First, social and economic organizations should share their willingness to implement policies in the provincial and provincial areas of Chungnam Province and cities and counties in terms of solving and improving various problems in the region. Based on this, it is required to upgrade the social and economic organization area. Second, the Chungnam region needs a shift in awareness that it is a social and economic organization that is a key factor in overcoming changes in the demographic structure due to industrial weakness and aging. Third, a positive shift in awareness is required by shifting awareness and strengthening education on social and economic organizations. To this end, it is necessary to raise the awareness level of local residents through public education and joint public-private education.

  • Aim: To investigate the effects of tetramethypyrazine (TMP) on proliferation and apoptosis of the human gastric carcinoma cell line 7901 and its possible mechanism of action. Methods: The viability of TMP-treated 7901 cells was measured with a 3-(4, 5-dimethyl-thiazol-2-yl)-2,5-diphenyltetrazolium bromide assay (MTT) and cell apoptosis was analyzed by flow cytometry. The distribution of cells in different phases of cell cycle after exposure of TMPs was analyzed with flow cytometry. To investigate the molecular mechanisms of TMP-mediated apoptosis, the expression of NF-${\kappa}Bp65$, cyclinD1 and p16 in SGC-7901 cells was analyzed by reverse transcription-polymerase chain reaction (RT-PCR) and western blotting. Results: TMP inhibited the proliferation of human gastric carcinoma cell line 7901 in dose and time dependent manners. Cell growth was suppressed by TMP at different concentrations (0.25, 0.5, 1.0, 2.0 mg/ml), the inhibition rate is 0.46%, 4.36%, 14.8%, 76.1% (48h) and 15.5%, 18.5%, 41.2%, 89.8% (72h) respectively. When the concentration of TMPs was 2.0mg/ml, G1-phase arrest in the SGC-7901 cells was significant based on the data for cell cycle distribution. RT-PCR demonstrated that NF-${\kappa}Bp65$ and cyclin D1 mRNA expression was significantly down-regulated in 7901 cells treated with 2.0 mg/ml TMP for 72h (p<0.05), while the p16 mRNA level was up-regulated (p<0.05). The protein expression of NF-${\kappa}Bp65$ and cyclin D1 decreased gradually with the increase in TMP concentration, compared with control cells (p<0.05), while expression of protein p16 was up-regulated (p<0.01). Conclusion: TMP exhibits significant anti-proliferative and pro-apoptotic effects on the human gastric carcinoma cell line SGC-7901. NF-${\kappa}Bp65$, cyclinD1 and p16 may also play important roles in the regulation mechanisms.

  • Background and Aims: Liver cancer is a major health problem in low-resource countries. Approximately 55% of all liver cancer occurs in China. Hebei Province is one of the important covering nearly 6% of the population of China. The aim of this paper was to explore liver cancer mortality trends during past 30 years, and provide basic information on prevention strategies. Methods: Hebei was covered covered all the three national surveys during 1973-1975, 1990-1992, and 2004-2005 and one provincial survey during 1984-1986. Subjects included all cases dying from liver cancer in Hebei Province. Liver cancer mortality trend and geographic differences across cities and counties were analyzed. Results: There were 82,878 deaths in Hebei Province during 2004-2005 with an average mortality rate was 600.9/10,000, and an age-adjusted rate of 552.3/10,000. Those dying of cancer were 18,424 cases, accounting for 22.2% of all deaths, second only to cerebrovascular disease as a cause of death. Cancer mortality was 133.6/100,000 (age-adjusted rate was 119.2/100,000). Liver cancer ranked fourth in this survey with a mortality rate of 21.0/100,000, 28.4/100,000 in males and 13.35/10,000 in females, accounting for 15.7%, 17.1% and 13.4% of the total number of cancer deaths and in males and females, respectively. The sex ratio was 2.13. Since the 1970s, liver cancer deaths of Hebei province have been increasing slightly. The crude mortality rates in the four surveys were 11.3, 16.0, 17.4, 21.0 per 100,000, respectively, with age-adjusted rates fluctuating during the past 30 years, but the trend also being upwards. There is a tendency for the mortality rates to be higher in coastal than mountain areas, and is relative lower in the plain area, with crude mortality rates of 25.3, 22.1, and 19.1 per 100,000, respectively. There were no notable differences in cride data between urban and rural, but the age-adjusted mortality rate in rural was much higher. Conclusion: Our study indicated that the mortality of liver cancer in Hebei Province is lower than the national average level. There is a slightly increase trend, especially in some counties. Liver cancer is a major health problem and it is necessary to further promote prevention strategies in Hebei province.

  • This study investigated oxygen consumption rate (OCR), $Q_{10}$ coefficient and ammonia excretion rate of the greenling, Hexagrammos otakii Jordan et Starks with the average body weight of 250 g in a semi-recirculated respiratory measuring system. The experiment was done under three different water temperatures (10, 15, $20^{\circ}C$) and five different ambient ammonia concentrations (0, 2.5, 5, 10, 20 mg/L). As the water temperature and ambient ammonia concentration increased the OCR has significantly increased (P<0.05). Given experimental conditions, the OCR of greenling were $50.8{\sim}159.4\;mg\;O_2\;kg^{-1}\;hr^{-1}$ and the relationship of water temperature (T) and ambient ammonia concentration (C) on the OCR were following: OCR = 41.3 - 1.87T - 7.38C + $0.463T^2$ + $0.66lC^2$ + 0.642TC - $0.011T^3$ - $0.010C^2$ - $0.031TC^2$ - $0.001T^2$C ($r^2$= 0.9226). $Q_{10}$ coefficients were $1.88{\sim}3.50$ for $10^{\circ}C$ to $15^{\circ}C$, $1.03{\sim}2.73$ for $15^{\circ}C$ to $20^{\circ}C$ and $1.40{\sim}1.90$ for $10^{\circ}C$ to $20^{\circ}C$, respectively. In general, the ammonia excretion rate tended to increase with increasing of the water temperature within normal ambient ammonia concentration. However, interestingly, it was observed that ammonia was absorbed rather than excreted above the ambient ammonia concentration of $2.5\;mg\;L^{-1}$, regardless of the water temperature. Thus, the largest ammonia absorption rate (AAR) was obserbed at the level of $98.4\;mg\;TAN\;kg^{-1}\;hr^{-1}$. The relationship ambient ammonia concentration (C) on AAR was following: Y = 1.61 + $10.9X^{0.7}$ ($r^2$ = 0.889).
