  • Fig leaves were extracted with methanol and then fractionated with ethyl acetate and various buffers to get active fractions and determined the antimicrobial activities. The acidic and phenolic fractions fractionated from the methanol extract of fig leaves showed the strong antimicrobial activities, but the basic and neutral fractions did not show any activities. The degree of antimicrobial activities of phenolic fraction against tested bacteria was higher than those of acidic fraction, but these against yeasts and mold were almost equivalent to those of acidic fraction. Especially, phenolic fraction was mostly affected on Staphylococcus aureus and Pseudomonas aeruginosa. Four antimicrobial substances purified from the phenolic fraction which showed the strongest antimicrobial activities among the fractions from fig leaves, were identified as psoralen($C_{11}H_{6}O_{3}$, MW. 186), bergapten($C_{12}H_{8}O_{4}$, MW. 216), ${\beta}$-sitosterol($C_{29}H_{50}O$, MW. 414) and umbelliferone ($C_{9}H_{6}O_{3}$, MW. 162).

  • In this thesis, we took some stalks, flowers, and leaves of the Hypericum ascyron L. which are able to propagate as mass in our wild to extract the dyeing solution, and cotton and silk were dyed using them in many different conditions. Silk was dyed darker than cotton with increasing the pH density. Silk was dyed darkest among Hypericum ascyron if pH was neutral. We found there was not a big difference between silk and cotton in the given condition considering 'Y' values vs. dyeing temperature. However cotton was dyed darker in hypericum ascyron. There was a rapid decreasing of 'Y' values after one to two hours and almost all of dyeing was completed at these times. We found there was a dyeing acceleration at the higher dyeing density and the lower 'Y' value. If the density was low, dyeing attachment was reduced by dyeing ability via the density of liquid in this plants. Silk was affected higher by mordant dyes in this plants. Fe and Cu had no effect on Hypericum ascyron.

  • The purpose of this study is to apply fashion design to developing dress design of mobile-phone game characters. As for the research methodology, first, market research has been carried out to extract main images from dress designs of game characters and to understand their socio-cultural meanings. Second, the fashion design, which ran be compared to the extracted images of game characters were selected. Third, analyses were done to find out the gap between the game character's dress designs and the fashion designs. The main images of game characters are revealed as erotic, romantic, heroic, grotesque. These images have been formed by psychological and socio-cultural effects such as stimulation, empathy, compensation, increase of female game player. The differences between the game character's dresses and the fashion designs are as follows; With regard to style, game dresses have silhouette distinguished from background, but fashion collection have blurred silhouette. In the aspect of color, while strong colors are mainly used in game dress, neutral rotors are preferred in fashion collection. As for texture, the expression of 'textures in game character's dress is so far limited due to the insufficient level of the concerned technology. However, the fashion design applying drape of fabrics are well-developed. Mobile-phone game players want reality in game design. Therefore, the effort to overcome the gaps between game dress and fashion design can contribute to the growth of game character design.

  • Two experiments were conducted to establish a digestible energy (DE) content prediction model of rapeseed meal for growing-finishing pig based on rapeseed meal's chemical composition. In experiment 1, observed linear relationships between the determined DE content of 22 rapeseed meal calibration samples and proximate nutrients, gross energy (GE) and neutral detergent fiber (NDF) were used to develop the DE prediction model. In experiment 2, 4 samples of rapeseed meal selected at random from the primary rapeseed growing regions of China were used for testing the accuracy of DE prediction models. The results indicated that the DE was negatively correlated with NDF (r = -0.86) and acid detergent fiber (ADF) (r = -0.73) contents, and moderately correlated with gross energy (GE; r = 0.56) content in rapeseed meal calibration samples. In contrast, no significant correlations were found for crude protein, ether extract, crude fiber and ash contents. According to the regression analysis, NDF or both NDF and GE were found to be useful for the DE prediction models. Two prediction models: DE = 16.775-0.147${\times}$NDF ($R^2$ = 0.73) and DE = 11.848-0.131${\times}$NDF+0.231${\times}$GE ($R^2$ = 0.76) were obtained. The maximum absolute difference between the in vivo DE determinations and the predicted DE values was 0.62 MJ/kg and the relative difference was 5.21%. Therefore, it was concluded that, for growing-finishing pigs, these two prediction models could be used to predict the DE content of rapeseed meal with acceptable accuracy.

  • An experiment was conducted to evaluate the effect of replacing barley and soybean meal in finishing diets with sesame hull (SH) on growth performance, digestibility, and carcass characteristics of Black goat kids. Twenty-one Black goat kids were assigned randomly to 0%, 10%, or 20% SH diets (7/diet). The study lasted for 63 d. Intakes of dry matter (DM), organic matter (OM), and crude protein (CP) of kids fed the 10% diet were greater (p<0.05) than for the 0% and 20% SH diets (p<0.10). Neutral detergent fiber (NDF) and acid detergent fiber (ADF) intakes were highest (p<0.05) for kids fed the 10% SH diet when compared to 0% and 20% SH diets. Ether extract (EE) intake was greater (p<0.05) for kids fed 10% and 20% SH diets when compared to 0% SH. Digestibilities of DM, OM, CP, NDF, and ADF were similar among all diets. However, sesame hull inclusion increased (p<0.05) EE digestibility. Final body weight, total gain, average daily gain (ADG), and feed conversion ratio were comparable among all diets. Cost of gain was lower (p<0.05) in kids fed 20% SH than the 0% SH diet, while there was no difference between the 10% SH diet and the other two diets. Dressing percentage, hot and cold carcass weights, non-carcass components, carcass cut weights, and meat quality parameters were not influenced by SH. Total fat percentage in the leg was greater (p<0.05) on 0% SH than on the 10% SH diet. Results of this study demonstrated that inclusion of sesame hull at levels of 10 or 20% did not influence the performance of Black goat kids, but the cost of gain was lower.

  • This study estimated the fermentation characteristics and nutrient value of corn-lablab bean mixture silages relative to corn silages. The effects of feeding corn-lablab bean mixture silages on nutrient apparent digestibility and milk production of dairy cows in northern China were also investigated. Three ruminally cannulated Holstein cows were used to determine the ruminal digestion kinetics and ruminal nutrient degradability of corn silage and corn-lablab bean mixture silages. Sixty lactating Holstein cows were randomly divided into two groups of 30 cows each. Two diets were formulated with a 59:41 forage: concentrate ratio. Corn silage and corn-lablab bean mixture silages constituted 39.3% of the forage in each diet, with Chinese wildrye hay constituting the remaining 60.7%. Corn-lablab bean mixture silages had higher lactic acid, acetic acid, dry matter (DM), crude protein (CP), ash, Ca, ether extract concentrations and ruminal nutrient degradability than monoculture corn silage (p<0.05). Neutral detergent fiber (NDF) and acid detergent fiber (ADF) concentrations of corn-lablab bean mixture silages were lower than those of corn silage (p<0.05). The digestibility of DM, CP, NDF, and ADF for cows fed corn-lablab bean mixture silages was higher than for those fed corn silage (p<0.05). Feeding corn-lablab bean mixture silages increased milk yield and milk protein of dairy cows when compared with feeding corn silage (p<0.05). The economic benefit for cow fed corn-lablab bean mixture silages was 8.43 yuan/day/cow higher than that for that fed corn silage. In conclusion, corn-lablab bean mixture improved the fermentation characteristics and nutrient value of silage compared with monoculture corn. In this study, feeding corn-lablab bean mixture silages increased milk yield, milk protein and nutrient apparent digestibility of dairy cows compared with corn silage in northern China.

  • The objective of this study was to investigate the effects of partial replacement of wheat hay with sun-dried (SOC) or acid-treated SOC (ASOC) olive cake on nutrient intake and performance of Awassi lambs. An additional objective was to study the effects of acid treatment of olive cake (OC) on its chemical composition and nutritive value. On DM basis, sun-drying of OC did not dramatically affect its chemical composition. On the other hand, treating SOC with phosphoric acid decreased (p<0.05) SOC contents of neutral detergent fiber. Twenty seven male lambs ($17.6{\pm}0.75$ kg body weight) individually housed in shaded pens were randomly assigned to one of three dietary treatments (9 lambs/treatment). Dietary treatments were formulated to be isocaloric and isonitrogenous by replacing 50% of wheat hay in the control diet (CTL) with SOC or ASOC and to meet all nutrient requirements. Dietary treatments had no effects on nutrient intake or digestibility except for ether extract. Lambs fed the SOC diet had (p = 0.05) faster growth rate, greater final body weight, and greater total body weight gain in comparison with the CTL diet, but not different from the ASOC diet. Additionally, lambs fed the SOC diet had greater (p = 0.03) hot and cold carcass weights than the ASOC diet, but not different from the CTL diet. However, feed conversion ratios and dressing percentages were similar among dietary treatments. In conclusion, replacing half of dietary wheat hay with SOC improved performance of Awassi lambs with no detrimental effects on nutrients intake or digestibility. No further improvements in the nutritive value of SOC and lambs performance were detected when SOC was treated with acid.

  • Pharmacological and preventive properties of Petroselinum sativum seed extracts are well known, but the anticancer activity of alcoholic extracts and oil of Petroselinum sativum seeds on human breast cancer cells have not been explored so far. Therefore, the present study was designed to investigate the cytotoxic activities of these extracts against MCF-7 cells. Cells were exposed to 10 to $1000{\mu}g/ml$ of alcoholic seed extract (PSA) and seed oil (PSO) of Petroselinum sativum for 24 h. Post-treatment, percent cell viability was studied by 3-(4, 5-dimethylthiazol-2yl)-2, 5-biphenyl tetrazolium bromide (MTT) and neutral red uptake (NRU) assays, and cellular morphology by phase contrast inverted microscopy. The results showed that PSA and PSO significantly reduced cell viability, and altered the cellular morphology of MCF-7 cells in a concentration dependent manner. Concentrations of $50{\mu}g/ml$ and above of PSA and $100{\mu}g/ml$ and above of PSO were found to be cytotoxic in MCF-7 cells. Cell viability at 50, 100, 250, 500 and $1000{\mu}g/ml$ of PSA was recorded as 81%, 57%, 33%, 8% and 5%, respectively, whereas at 100, 250, 500, and $1000{\mu}g/ml$ of PSO values were 90%, 78%, 62%, and 8%, respectively by MTT assay. MCF-7 cells exposed to 250, 500 and $1000{\mu}g/ml$ of PSA and PSO lost their typical morphology and appeared smaller in size. The data revealed that the treatment with PSA and PSO of Petroselinum sativum induced cell death in MCF-7 cells.

  • The aim of this study was to determine the nutritive value of some legume species in salt-affected soils of South-East Anatolian region using chemical composition and in vitro gas production kinetics. In this study, Lotus corniculatus, Trifolium alexandrinum, Medicago sativa were sown and tested in four different locations. A 3 by 4 factorial design with 3 legume species and 4 salt levels (non salty electrical conductivity (EC)<4 dS/m; low salt: 4 dS/m>EC<8 dS/m, medium saline: 8 dS/m>EC<16 dS/m and high salt: 16 dS/m>EC) was used in the study. Results indicated that salinity and plants had no significant effect on ash and ether extract. Dry matter (DM), acid detergent fiber, digestible dry matter, dry matter intake (DMI) were affected by plant, salinity and plant${\times}$salinity interaction. On the other hand neutral detergent fiber, relative feed value (RFV), and DMI were affected by salinity and plant${\times}$salinity interaction. Mineral contents were affected by plant species, salinity and salinity${\times}$plants interactions. In vitro gas production, their kinetics and estimated parameters such as were not affected by salinity whereas the gas production up to 48 h, organic matter digestibility, metabolizable energy (ME), and net energy lactation ($NE_L$) were affected by plant and plant${\times}$salt interaction. Generally RFVs of all species ranged from 120 to 210 and were quite satisfactory in salty conditions. Current results show that the feed value of Medicago sativa is higher compared to Lotus corniculatus and Trifolium alexandrinum.

  • Ficin, a proteolytic enzyme in Fig latex, was extracted and purified with using ammonium sulfate and CM-cellulose column chromatography, respectively, and studied for its chemical properties. The disc gel electrophoresis showed one major and three minor bands for $(NH_4)_2SO_4$ extract and only one band showed after CM-cellulose chromatography. The optimum conditions for ficin activity was found to be pH 7.0 and $50^{\circ}C$. The amino acids composition of the purified ficin were 21.8% as acidic, 3.5% as basic and 74.7% as neutral amino acids. The amino acids analysis indicated that the ficin was composed of 174 amino acids residue having molecular weight of 19,500.
