  • A series of experiments were designed to determine the feasibility of single dose of FSH as an effective superovulation method in rabbits. The superovulation treatments examined comparatively were as follows: 1) a single injection of 100 IU PMSG, 2) Multiple injections of 1 IU Super-OV of 2X daily for 3 days, 3) Multiple injections of 6.6 rng Folltropin-V 2X daily for 3 days, 4) Multiple injections of 13.3 rng Folltropn-V l$\times$ daily for 3 days, 5) Single injection of 40 mg Folltropin-V solved in 10% PVP, and 6) Single injection of 40 mg Folltropin-V dissolved in 25% PVP. The results obtained were as follows: The nurnher of ovulation points in the single injection of 40 mg Folltropin-V dissolved in 25% PVP and multiple injections of 6.6 mg Folltropin-V 2X daily for 3 days was averaged 44.6 and 39.2, respectively, which were significantly (P<0.05) more than in a single dose of PMSG or multiple doses of Super-OV. The number of total ova recovered in the single injection of 40 mg Folltropin-V dissolved in 25% PVP and multiple injections of 6.6 mg Folltropin-V 2X daily for 3 days was averaged 30.4 and 25.9, respectively, which were significantly (P<0.05) more than in the single dose of PMSG or multiple doses of Super-OV. A similar result was obtained for the number of fertilized ova recovered from the above six treatments. From the above results it was concluded that a single injection of 40 mg Folltropin-V dissolved in 25% PVP could be an effective and simple method for superovulation in rabbits.

  • At present, it is very common to use techniques beyond the 2D (two-dimensional) in animations which are found in motion pictures, OVA and TV series. As you can see, PIXAR and Disney have reduced their 2D departments and recently put more effort into 3D (three-dimensional) animation. There is no doubt that producing 3D animation is the big trend. Along with this trend, the national education institutions and the national support policies are also changing to be supportive of 3D animations. We, however, should ask ourselves, if we are on the right track with this change. Through the analysis of the methods of creating 2D animation which we should keep as it is, but instead we import and incorporate with 3D techniques of Japanese 2D animation, I would like to present the importance and the significance of the 2D animation and also to suggest an effective way to create 2D fused with 3D computer graphics techniques.

  • Objectives : The aim of this study is to investigate the antiallergic effects of YTT on allergic rhinitis by regulation of peroxisome proliferator-activated receptor gamma (PPAR-$\gamma$). Methods : The thirty rats were divided into three groups : normal group, control (allergic rhinitis elicited) group, sample (Yeotaectonggi-tang treated after allergic rhinitis elicitation) group. To induce allergic rhinitis in control group and sample group, rats were sensitized intraperitoneally with 0.1% ovalbumin(OVA) solution 3 times at intervals of 1 week. Then intranasal sensitization was performed by diffusing 0.1% ovalbumin(OVA) solution 3 times at intervals of 2 days. After that time rats in sample group were oral administration treated by YTT for 7days. The change of the amounts of eosinophil, substance P, MIP-2, PPAR-$\gamma$, IL-4, iNOS were observed in each group. we used the statistical method of ANOVA test(p<0.05). Results : The number of eosinophil in sample group noticeably decreased than control group. And the decrease of substance P and MIP-2 positive reaction were observed in mucosa. YTT inhibited IL-4 and iNOS production, mucus secretion, activation of mast cells and fibrosis remodeling by regulation of PPAR-$\gamma$ activation. Conclusion : According to the above results, it is considered that YTT mitigated mucosa damage on the mice model with allergic rhinitis by regulation of PPAR-$\gamma$.

  • Background: Immunomodulators enhancing MHC-restricted antigen presentation would affect many cellular immune reactions mediated by T cells or T cell products. However, modulation of MHC-restricted antigen presentation has received little attention as a target for therapeutic immunoregulation. Here, we report that lectins isolated from mushroom Fomitella fraxinea enhance MHC-restricted exogenous antigen presentation in professional antigen presenting cells (APCs). Methods: Lectins, termed FFrL, were isolated from the carpophores of Fomitella fraxinea, and its effects on the class I and class II MHC-restricted presentation of exogenous ovalbumin (OVA) were examined in mouse dendritic cells (DCs) and mouse peritoneal macrophages. The effects of FFrL on the expression of total MHC molecules and the phagocytic activity were also examined in mouse DCs. Results: DCs cultured in the presence of FFrL overnight exhibited enhanced capacity in presenting exogenous OVA in association with class I and class II MHC molecules. FFrL increased slightly the total expression levels of both class I (H-$2K^b$) and class II (I-$A^b$) MHC molecules and the phagocytic activity of DCs. Antigen presentation-enhancing activity of FFrL was also observed in macrophages isolated from mouse peritoneum. Conclusion: Lectins isolated from the carpophores of Fomitella fraxinea increase MHC-restricted exogenous antigen presentation by enhancing intracellular processing events of phagocytosed antigens.

  • An investigation was carried out to obtain basic information needed to develop methods for artificial propagation and conservation of the mottled skate Raja pulchra, an important food resource in western Korea that has declined from overfishing. In this paper we provide evidence of multiple spawning and describe properties of the ovary, and morphology of the egg capsule and the fully-formed offspring. The vitellogenic follicles in the ovary was $179.8{\pm}57.1$ (54~247) and can be classified into five size groups, which the last group of ova are considered as the moving to the capsule gland where fertilization and encapsulation of ova take place. The morphology of the egg capsule of R. pulchra is unique among the species of the family Rajidae and showed multi-embryo characteristics, having two to six yolks in each capsule. The adaptive morphological changes of larvae developing inside the egg capsule are described based on specimens extracted from the capsule.

  • Objectives : To clarify the possible effect of Lycium chinese Mill (LC)., Morus alba L (MA)., and Lycium chinese Mill. +Morus alba L. (LC+MA), we have examined their influence on the development of pulmonary eosinophilic inflammation in the asthmatic murine model. Methods : Female Balb/c mice (5weeks) were immunized on two different days (21 days and 7 days before inhalational exposure) by intraperitonial injections of 0.2ml alum-precipitated Ag containing $100{\mu}g$ of OVA bound to 4 mg of aluminum hydroxide in PBS. Seven days after the second sensitization, mice were exposed to aerosolized ovalbumin for 30 minutes/day on 3 days/week for 8 weeks (at a flow rate of 250 L/min, 2.5% ovalbumin in normal saline) and, LC, MA, and LC+MA (500 mg/kg) were orally administered 3 times per a week for 8 weeks. Results : The suppressive effect of LC, MA, and LC+MA were demonstrated by the accumulation of eosinophills into airways, with the reduction of eosinophil, total lung leukocytes numbers. These were correlated with the marked reduction of IL-5, IL-13 and IL-4 levels in the BALF and serum. OVA-specific IgE levels were also decreased in serum and BAL from these mice. LC, MA, and LC+MA decreased eosinophil CCR3 expression and CD11b expression in lung cells. Conclusions : These results indicate that LC, MA, and LC+MA have high inhibitory effects on airway inflammation and hyper-responsiveness in the asthmatic murine model. The suppression of IL-5, IgE, eosinophil CCR3 expression and CD11b expression, and the increase of IFN-${\gamma}$ production in BALF seem to contribute to this effect. Hence, the results indicated that LC, MA, and LC+MA could act as a immuno-modulator which possesses anti-inflammatory and anti-asthmatic property by modulating the imbalance between Th1 and Th2 cytokines.

  • Fine wool sheep (n=18) maintained in a tropical environment were allocated to three treatment groups. Estrus was induced with two injections of $PGF_{2{\alpha}}$ (10 mg. im) at 10 days interval. Superovulation treatment started 2 days prior to the second injection of $PGF_{2{\alpha}}$. Each ewe was treated with a total dose of 25 units FSH (Super-OV) i.m. every 12 hover 3 days; Group 2 were also injected i.m. with 200 IU PMSG at the first injection of FSH; Group 3 was treated as in Group 2 and also with GnRH ($4{\mu}g$ Buserelin) at the onset of estrus. The ewes in estrus were mated with a fertile ram. Ovarian examination and recovery of embryo and ova were performed at laparoscopy and laparotomy on day 3 or 4 after mating. Data for onset of estrus, duration of estrus, number of corpora lutea (CL), number of unnovulated large follicle (LF), embryo recovery rate, embryo quality and fertilization recorded for the 3 groups. Ewes in the Group 1 set in estrus later (p<0.05; $50.0{\pm}7.29h$) than the ewes in Group 2 ($24.5{\pm}3.58$) and 3 ($32.5{\pm}3.58h$). The duration of estrus, ovarian size and ovarian response (number of CL and LF) did not differ significantly (p>0.05) among the 3 groups. The proportion of ewes with a superovulatory response (${\geq}2$ CL) was the lowest (50%) in Group 1 treated with FSH alone but ova/embryo recovery (100%) and fertilization (100%) was significantly (p<0.05) higher than Group 2 (58.3 and 85.7%, respectively) and Group 3 (48.6 and 50%, respectively). It is concluded that in tropical fine wool sheep, there is no difference in the 3 treatments for yield of good quality embryos but ovarian response and ovulation rate increased on additional use of PMSG and GnRH respectively to FSH alone.

  • Objective: The purpose of this study was to evaluate the effect of Samjawhadam-jeon (SJHDJ; 三子化痰煎) on immune cells in OVA-induced asthmatic mice. Material and Methods : C57BL/6 mice were injected, inhaled and sprayed with OVA for 12 weeks (four times a week) for asthma induction. Two experimental groups were treated with different concentrations of SJHDJ group (400 mg/kg) extracts and cyclosporin A (10 mg/kg) for the latter 8 weeks. At the end of the experiment, the mouse lung. peripheral lymph node (PLN) and spleen were removed and immune cells were analyzed by flow cytometer. Results : Lung weight, total cells in lung, PLN, and spleen of the SJHDJ group decreased significantly compared with that of the control group. Number of $CD3e^+/CD69^+$, $CD3e^+/DX5^+$ cells in lung, PLN and spleen, number of $CD3^+$ cells in PLN and spleen, number of $CD3e^-/CCR3^+$ cells in lung and PLN, and number of $B220^+/IgE^+$ cells in PLN of the SJHDJ group decreased compared with that of the control group. Number of $CD4^+/CD25^+$ cells in PLN and spleen of the SJHDJ group increased compared with that of the control group. Conclusion : These results demonstrate that SJHDJ will be a desirable alternative therapy for allergic asthma by inhibiting the expression of immune cells.

  • An enzyme-linked immunosorbent assay (ELISA) was established for the detection of zearalenone by using monoclonal antibodies produced by Z-M-26 hybridoma cells when injected into a mouse and zearalenone-oxime-OV A conjugate. Zearalenone-oxime-OV A conjugates were diluted with carbonyl buffer, coated to 96 well microtiter plates at $4^{\circ}C$ overnight and blocked with 1% BSA overnight. One thousand times diluted antibody solution together with standard zearalenone or sample was added to 96-well microtiter plates and stood overnight. A secondary antibody conjugated with HRP was added and an hour later, enzyme substrate (TMBZ) solution was added for color develpment. Mter 30 minutes, coloring reaction was terminated by adding 2 N $H_2S0_4$ and the O.D. was measured at 450 nm. Detection range of this method was about 0.1~100 ppb. The established indirect competitive ELISA method was suitable for a rapid and effective analysis of zearalenone in agricultural products.

  • A B cell-specific growth substance (BGS) was isolated from the slime layer of Bacillus licheniformis E1. Unlike LPS, the BGS was not affected by polymixin B, an inhibitor of LPS, or by TLR4, and resulted in the growth of B cells. When BALB/c mice were treated with the BGS, the B cell population was found to increase in both the bone marrow and the spleen, with a marked increase after 24 h in the bone marrow and after 48 h in the spleen. When using antibodies to B cell lineage-restricted surface molecules to analyze the B cell population changes resulting from treatment with the BGS, an increase in immature B cells ($IgM^+$ and $AA4.1^+$) and mature B cells ($IgM^+$ and $IgD^+$) was found in the bone marrow 24 h after treatment with the BGS, whereas a decrease in mature B cells and increase in $IgG^+$ B cells were found in the spleen. When the BGS and OVA antigen were injected into the peritoneal cavity of BALB/c mice, this resulted in a high OVA-specific antibody titer in the sera, similar to that induced by aluminum hydroxide. Therefore, it is anticipated that the mass production of the BGS by B. licheniformis E1 could be used for studies of B cells in immunology, and contribute to the development of a new adjuvant for vaccine manufacture.
