  • A total of 225 ISA Brown layers, 63-wk-old, were used in a 5-wk feeding trial to measure the effect of dietary canthaxanthin(0, 50, 100, 200, and 300mg/kg feed) on its accumulation in various body parts and the egg yolk. There were three replications per treatment and 15 birds per replication. The redness(a$\^$*/) and yellowness(b$\^$*/) of wing and thigh skin significantly(P<0.05) increased when canthaxanthin was fed at 2200 and 250mg/kg feed, respectively. However, the color of breast skin was not significantly affected by the canthaxanthin supplementation. Skin lightness(L$\^$*/) was not influenced by the dietary canthaxanthin. The dietary canthaxanthin supplementation did not significantly affect the redness or the yellowness of breast and thigh muscles. However, feeding canthaxanthin at 300mg/kg, compared to the control(0mg/kg feed), significantly(P<0.05) decreased the lightness of wing and breast muscles. Feeding of canthaxanthin for 1-3d also significantly increased the color of egg yolks. In conclusion, canthaxanthin can be used to improve the color of skin and egg yolks, but it should be used cautiously because too intense egg yolk redness could be rejected by consumers.

  • We performed a study to obtain kinematic data on the characteristics of spike serving techniques used by volleyball players, including other basic data that will be useful for in-field applications. We used three-dimensional videography to compare good tough serves and serve errors. The subjects were 3 left attackers whose spike serves were videographed (60 fileds/s). The three-dimensional coordinates were calculated using the direct linear transformation method and then analyzed using the Kwon 3D software program version 3.1. There was no difference in time elapsed. However, the vertical displacement of the center of body mass(CM) differed between the 2 types of serves: in successful serves, the CM tended to be lower, as did the maximum ball height at the time of hitting. Further, the higher the level of the hitting hand was at the moment of impact, the higher was the likelihood of scoring points. In good serves, the players tended to accelerate their CM movement just before jumping to hit the ball and descend rapidly at the moment of hitting. The hand speed along with ball velocity during the impact was proven to be higher in successful serves. Moreover, in successful serves, the shoulder angles increased to a greater extent while the elbow angles were maintained constant. This possibly resulted in faster and more precise serves. An important observation was that the angle of trunk inclination during the jump did not increase with the swing of the shoulders, muscle tendon complex.

  • This study was conducted to investigate the dietary effects of germinated and fermented (with Monascus pupureus) soybean screenings (GFS) on growth performance and meat quality in broiler chicken. A total of 750 1-day-old Ross ${\times}$ Ross male broiler chicks were randomly allocated into five groups (five replications with 30 birds each) and fed experimental diets for 5 wks as follows: Group 1, negative-control (antibiotics-free diet); Group 2, positive-control (negative-control with 10 ppm of Avilamycin); Group 3, negative-control with 0.3% GFS; Group 4, negative-control with 0.5% GFS; Group 5, negative-control with 1% GFS. The final body weight of each group fed a diet containing 1% GFS was significantly higher than that of the negative-control group. The feed conversion ratios of all groups fed diets containing GFS and the positivecontrol group were significantly improved compared to the negative-control group during the whole period (p<0.05). The relative weights of various organs along with the activities of serum glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) were not influenced by the dietary treatments. The levels of total serum cholesterol in groups fed diets containing 0.5% and 1% GFS were more significantly lowered compared to those of the control groups without GFS (p<0.05). There were no significant differences in the cecal microflora profiles among the groups. Further, the dietary treatments did not influence the physico-chemical properties of the edible meat, including the shear force, pH, meat color (CIE $L^*$, $a^*$ and $b^*$), and content of malondialdehyde (MDA). Cooking loss of breast muscle in the groups fed GFS was significantly lowered compared to that of the negative control group (p<0.05). These results indicate that dietary GFS could improve growth performance in broiler chicken and may affect meat quality in some instances.

  • Anabolic steroids have similar structures to testosterone, both of which promote the growth of muscle mass and increase strength. However, the side effects of anabolic steroid use may lead to heart attacks or strokes. Additionally, the excessive use of steroids inhibits the production of the sex hormones in the body via a negative feedback loop, which results in testicular atrophy in males and amenorrhea in females. Currently, the method of choice used to test for the presence of anabolic steroids is GC-MS. However, GC-MS methods require chemical derivatization of the steroid sample to ensure compatibility with the analytical method; therefore, analysis of many different samples is difficult and time consuming. Unlike GC-MS, the liquid chromatography-quadrupole-time of flight mass spectrometry (LC-Q-TOF-MS) method is suitable for many samples. Twenty-two different anabolic steroids were analyzed by LC-Q-TOF-MS with various collision energies (CE). Accurate mass spectral data were obtained using a Q-TOF-MS equipped with an electro-spray ionization source and operated in the positive MS/MS mode for several classes of steroids that are often the targets of testing. Based on the collected data, fragmentation pathways were carefully elucidated. The high selectivity and sensitivity of the LC-Q-TOF-MS instrument combined with these fragmentation pathways offers a new approach for the rapid and accurate screening of anabolic steroids. The obtained data from the 22 different anabolic steroids will be shared with the scientific community in order to establish a library to aid in the screening of illegal anabolic steroids.

  • In this study, we investigated the changes in the physiological and histological traits of a sea squirt (Halocynthia roretzi) with the emergence of the soft tunic syndrome induced by the water temperature control (6, 9, 12, 15, 18, 21, 24 and $27^{\circ}C$). It was observed that the induction rate of the soft tunic syndrome was highest at $15^{\circ}C$, but lowest at $24^{\circ}C$. Based on the tunic color condition and contraction strength, the whole process were classified into 4 stages as S0, S1, S2 and S3. Interestingly, there were significant differences in oxygen consumption and filtration rate were observed during S0-S3. The most distinctive aspects were change of blood cell composition at stage S3, whereas multi-vacuole cell ratio was decreased by 1/2 and morula cell ratio expanded about 10 times during S0-S3. Further, change of organ structure started following the syndrome such as degeneration of epithelial cells, microfilaments, increment in hemocytes and damage in muscle fiber have been detected in tunic, siphon, branchial sac, body wall musculature and pyloric gland. Briefly, our study results indicated that the normal physiological functions of the sea squirt can be affected due to the soft tunic syndrome induced by water temperature.

  • This experiment was conducted to investigate the effects of dietary garlic powder (GP) on growth performance and mRNA expression of hepatic 3-hydroxy-3-methylglutaryl-CoA reductase (HMG-CoA reductase) in broiler chickens. Day-old male chicks (Ross, n=270) were fed diets containing 0% [positive control (PC) with antibiotics or negative control (NC) without antibiotics], 1%, 3% and 5% GP for 6 wks. There were no significant differences in feed intake among the treatments throughout the experimental period. Body weight gains in groups fed dietary GP at 3% and 5% were significantly higher than that of NC group (P<0.05). Feeding GP up to 5% did not exert any adverse effect on weight gain and feed intake. There were no significant differences in the relative weights of liver, spleen, cecum and breast muscle. The content of meat cholesterol in GP containing dietary groups tended to be reduced as compared to NC group. Average infectious bronchitis antibody titers in chicks fed GP containing diets were significantly higher than that of NC group (P<0.05). The mRNA expression of hepatic HMG-CoA reductase was reduced by dietary GP. These results indicate that dietary GP has growth promoting effects and tended to alter cholesterol metabolism in broiler chickens.

  • In the Encyclopedia Medica Koreana(Dongeuibogam), I have researched 245 prescriptions in which Panax Ginseng plays an important role. And I have got the following results. The healing scope and frequency of ginseng-mainly-included prescriptions are Child Part 29(11.83%), Violent Cough Part 23(9.38%), Sick-by-Cold Part 21(8.57%), Oncosis Part 16(6.53%), Overwork Part 14(5.71%), Gynecologic Part 14(5.71%), Internal Part 13(5.3%), Apoplexy Part 11(4.48%), Mind Part 10(4.08%) and Fecal Part 10(4.08%) prescriptions. And also each of Nausea Part, Anger Part, and Spirit parts has the same 5 (2.04%) prescriptions. And each of Qi Part, Diabetes Meatus Part, Malaria Part, and Humoral Part has 4(1.63%) prescriptions. And each of Foot Part, Choleraic Part, Genital Part, Blood Part, and Voice Part has 3 (1.2%). All of these prescriptions cover 88.88%. And besides listed parts above, Panax Ginseng is all used in 48 Parts: Body-Mind Part. Mouth-Tongue Part, Breast Part, Muscle Part, Swelling Part, Urine Part, Epidermis Part, Heat Part, Anus Part, Stomach Part, Eye Part, Laryngopharynx Part. Uterus Part" Heavy Stomach Part, Head Part, Pulse Part, Hair Part, Navel Part, Emetic Part, Costal Part, Edema Part, Vomiting Part, Superstitious Part, and Cardiac Part, etc. Of the prescriptions in which Panax Ginseng plays an important role, the most representative diseases, which more than 86.8% prescriptions cure, are shock, numbness from cold, Taeeum disease, oncosis, overwork, sick from eating, numbness of extremities, diarrhea, tachycardia, forgetfulness, nausea, heat from kidney, nocturnal emission, short breath, diabetes meatus, malaria, sweating, sweating overnight, beriberi, cholera, insomnia from enervation, sialitis, navel pain, hemorrhage, and loss of voice. The pathology of the prescriptions in which Panax Ginseng plays an important role is divided into the organ problems, six natural factors, seven extreme feelings, unbalanced humoral status, overwork, and, unbalance of qi and blood. Spleen, heart, and uterus is the main cause of organ problems; wind and cold are the main cause of six natural factors; heavy humors are the main cause of unbalanced humoral status; the stasis of seven feelings are the main cause of seven extreme feelings; the lack of stamina and overwork are the main cause of the overwork; the lack of qi, the lack of blood, and, the lack of qi and blood are the main cause of the unbalance of qi and blood. After I have researched the contents of the prescriptions in which Panax Ginseng plays an important role, I could understand the addition of the different prescriptions, combination of medicines, and the role of medicine groups associated with Panax Ginseng. So from now on, the results I have got could be used as the data which show the theoretical basis on the prescriptions.

  • The augmentation of soft tissue defects is one of the critical problems in the oral and maxillofacial surgery. Various types of graft materials, both autologous and non-autologous, have been used for the augmentation of soft tissue in the facial region. However, it is not easy to choose an ideal material for soft tissue augmentation because each has its advantages and disadvantages. An ideal graft material should meet the following criteria : it should not leave a scar at the area from which it was taken; should have less likelihood of causing infection; should feel natural after implanted; and should be not absorbed. Among the materials meeting these criteria, human dermis and artificial dermis are commonly used for clinical purposes. The present study was aimed to investigate and compare the resorption rate and the histological change following the use of the autologous dermis, the human homogenous dermis $Alloderm^{(R)}$, and the artificial dermis $Terudermis^{(R)}$ to reconstruct the soft tissue defect. Twenty mature rabbits of either sex, weighing about 2 ㎏, were used. Each rabbit was transplanted with the autologous dermis, $Alloderm^{(R)}$, and $Terudermis^{(R)}$ size $1{\times}1-cm$ at the space between the external abdominal oblique muscle and the external abdominal oblique fascia. They were then divided into 4 groups (n=5 each) according to the time elapsed after the surgery: 1, 2, 4, and 8 weeks. The resorption rate was calculated by measuring the volume change before and after the transplantation, and H-E stain was preformed to observe the histological changes. The resorption rate after 8 weeks was 21.5% for the autologous dermis, 16.0% $Alloderm^{(R)}$, and 36.4% $Terudermis^{(R)}$, suggesting that $Alloderm^{(R)}$ is the most stable while $Terudermis^{(R)}$ is the most unstable. In microscopic examinations, the autologous dermis graft was surrounded by inflammatory cells and showed foreign body reactions. The epidermal inclusion cyst was observed in the autologous dermis graft. $Terudermis^{(R)}$ and $Alloderm^{(R)}$ demonstrated neovascularization and the progressive growth of new fibroblast. The results suggest that $Terudermis^{(R)}$ and $Alloderm^{(R)}$ can be availably for substituting the autologous dermis.

  • Mccroorchis spinuLosw Ando, 1918 (Digenea: Nanophyetidael is redescribed based on adult flukes recovered from experimental mice, rats and cats which were fed with metacercariae encysted in the muscle of the crayfish, Cambnroines similis. A total of 117 adult flukes were harvested from the small intestine of the experimental animals at S-21 days post-infection. The worm recovery rate was 31-37%, not significantly different among the three kinds of animals. The metacercariae were round, 0.18 mm in average diameter, encysted with two layers of thick walls, and possessing a stylets on the oral sucker and Y- shaped exc retory bladder. The adult flukes were oval, 0.66-0.71 mm long and 0.36-0.41 mm wide, and characterized by the presence of a stylet on the oral sucker, variable location of the ovary near the mid-portion of the body, bilobed seminal vesicle, and anterolateral location of two testes. These morphological features were a little different from the original description, hence, an emended version of M. spinulosw was given. M. spinuLosw is a new intestinal trematode of animals and possibly man in Korea.
