  • Various endometrial genes in ruminant ungulates are regulated by conceptus interferon tau (IFNT). However, the effect of each IFNT isoform has not been carefully evaluated. In this study, the effects of 2 IFNT isoforms, paralogs found in utero, and interferon alpha (IFNA) on uterine epithelial and Mardin-Darby bovine kidney (MDBK) cells were evaluated. Expression vectors of the bovine interferon (bIFNT) genes bIFNT1, bIFNTc1, and bIFNA were constructed, and recombinant bIFNs (rbIFNs) were produced by 293 cells. Bovine uterine epithelial or MDBK cells were cultured in the presence or absence of increasing concentrations of each rbIFN for 24, 48, or 72 h. Transcript levels of the IFN-stimulated genes (ISGs) ISG12, ISG15, MX1, and MX2 were analyzed using quantitative reverse transcription-polymerase chain reaction. These messenger RNAs were up-regulated by rbIFN in a time- and concentration-dependent manner. In the epithelial cells, the ISG12 transcript level increased at 48 h after rbIFN treatment but slightly decreased at 72 h, whereas the transcript level of ISG15 increased at 24 h and was maintained through 72 h. Expressions of MX1 and MX2 increased at 72 h after rbIFN treatment. MX1 expression increased in all treatment groups, but MX2 increased only by bIFNTc1. In MDBK cells, the expression of ISG12 was increased by bIFNT1 and bIFNTc1 after 24 and 72 h; however, it was unchanged by rbIFNA. ISG15 increased following the same pattern as that seen in uterine epithelial cells, and MX1 showed a similar expression pattern. MX2 expression was increased by bIFNTc1 treatment in uterine epithelial cells, and its expression was increased by both bIFNT1 and bIFNTc1 in MDBK cells. These results show that epithelial and MDBK cell responses to IFNs differ, suggesting that IFNs possess common functions, but may have acquired different functions following gene duplication.

  • B$_2$O$_3$ added Ba(Mg$_{1}$3/Nb$_{2}$3/)O$_3$ (BBMN) ceramics were not sintered below 900 $^{\circ}C$. However, when CuO was added to the BBMN ceramic, it was sintered even at 850 $^{\circ}C$. The amount of the $Ba_2$B$_2$O$_{5}$ second phase decreased with the addition of CuO. Therefore, the CuO additive is considered to react with the B$_2$O$_3$ inhibiting the reaction between B$_2$O$_3$ and BaO. Moreover, it is suggested that the solid solution of CuO and B$_2$O$_3$ might be responsible for the decrease of the sintering temperature of the specimens. A dense microstructure without pores was developed with the addition of a small amount of CuO. However, a porous microstructure with large pores was formed when a large amount of CuO was added. The bulk density, the dielectric constant ($\varepsilon$$_{r}$) and the Q-value increased with the addition of CuO but they decreased when a large amount of CuO was added. The variations of those properties are closely related to the variation of the microstructure. The excellent microwave dielectric properties of Qxf = 21500 GHz, $\varepsilon$$_{r}$ = 31 and temperature coefficient of resonance frequency($\tau$$_{f}$) = 21.3 ppm/$^{\circ}C$ were obtained for the Ba(Mg$_{1}$3/Nb$_{2}$3/)O$_3$+2.0 mol%B$_2$O$_3$+10.0 mol%CuO ceramic sintered at 875 $^{\circ}C$ for 2 h.h.2 h.h.

  • Sexual dimorphism is the most conspicuous difference between the sexes. This study examines possible sexual dimorphism and the relative growth patterns of morphometric characteristics in the marine medaka, Oryzias dancena for their potential to help differentiate between males and females of this species. The von Bertalanffy growth parameters estimated by a non-linear regression method were $L_{\infty}=30.2mm$, K=3.22/year, and ${\tau}_0=-0.05$. All 18 characteristics measured showed a difference between males and females from 70 days after hatching. Each of these characteristics were significantly different between sexes (ANCOVA, P<0.05), and the ratio of standard length between sexes showed that males were larger than females for all five morphometric measurements. Fin length measurements were taken for 21 distances of anal fin and 7 distances of dorsal fin between landmarks. There were all differences for all dorsal fin rays between the males and the females and there is significant difference in 70 days after their hatch when the sexual dimorphism is presented. The significant difference (P<0.05) in fin ray for male and female was more greatly seen as they grow. Male marine medaka showed more rapid growth than females, with longer length, dorsal fins and anal fins. Differences in these characteristics will be useful during experiments when it is necessary to differentiate between sexes of marine medaka.

  • Medical Internal Radiation Dose(MIRD) schema was developed for calculating the absorbed dose from the administered radiopharmaceuticals. With the biological distribution data and the physical properties of the radionuclide we can estimate the absorbed dose by the MIRD schema. For the thyroid cancer patients received $^{131}I$ therapy, the absorbed dose to the bone marrow is the limiting factor to the administered dose, and the duration of admission is deter-mined by the retained activity in the whole body. To monitor the whole body radioactivity, we used Eberline Smart 200 system using ionization chamber as a detector. With the time activity curve of the whole body, total body residence time was obtained. From the ICRP publication 53, the residence times of the source organs, such as kidney, urinary bladder content and stomach, were used to calculate the absorbed doses of the target organs, such as stomach, red marrow, bladder wall and remaineder total body. In 8 thyroid cancer patients with 175 mci of $^{131}I$ administered orally, the mean absorbed dose in the bladder wall was 375.1, in the stomach 285.1, red marrow 25.4 and total body 22.4 rad respectively. For the monitoring of the large administered activity, this method seemed to be quite useful.

  • The study was carried out to develop the powdered smoked-dried anchovy products as a natural flavoring substance. The processing conditions, chemical and taste compounds of products were as follows: The raw anchovy were washed, and then boiled 5 minutes in $5{\sim}6%$ NaCl and 1.0% sodium erythorbate solution. Boiled anchovy were smoked in smoking house at $40^{\circ}C$ for 4 hours as the first stage, and then increased temperature up to $80^{\circ}C$ as the second stage, and finally smoked 8 hrs at $80^{\circ}C$ to maintain the moisture content between 9 and 10 percent. The smoked-dried anchovy were pulverized and screened to be 50 mesh of particle size, and finally packed in PET/Al/CPP film bag. The moisture, crude lipid content and salinity of powdered smoke-dried anchovy were 9.4%, 9.6% and 6.9%, respectively. Fatty acid composition of product was mainly consisted of polyenes (43.4%) such as 22 : 6 and 20 : 5, followed by saturates (36.9%), monoenes (19.7%). The principal taste compounds of product were IMP, 466.5 mg/100g; free amino acids such as His, Tau, Pro, Lys, Ala and Glu, 1179.2 mg/100g; non-volatile organic acids such as lactic acid and succinic acid, 617.9 mg/100g; total creatinine, 595.9 mg/100g; small amount of betaine and TMAO. To make a instant soup, it was desirable for taste of products that powdered smoked-dried anchovy were mixed with 20% salt, 4.0% sugar, 3.0% MSG, 1.0% onion powder, 1.0% garlic powder and 1.0% black pepper.

  • The purpose of this study was to investigate health promotion lifestyle profiles of the Korean elderly in Japan. The subjects of this study were 202 elders in Aichi prefecture. The method of this study questionnaires interviews, and a self-administered questionnaire from the 1st to the 20th of April in 2000. This study tool was based on Walker et al. (1987)'s Health Promotion lifestyle Profiles (HPLP). Analysis of the data used an SPSS/pc+ WIN 9.0 program. Data analyses were conducted by using frequency, percentage, t-test, ANOVA. Pearson correlation, Kendal tau and Stepwise Multiple Regression. The results were as follows: 1. The average score of Health Promotion Lifestyle Profiles of Korean elderly in Japan was 2.72(SD=0.40). On the sub-scale of Health Promotion Lifestyle Profiles: nutrition(M = 3. 06), self-actualization(M =2.99), interpersonal support (M=2.81), stress management (M=2.68) revealed higher scores, whereas the scores of health responsibility(M=2.52), and exercise(M=1.92) were lower. 2. Health Promotion Lifestyle Profiles were significantly different by age (F = 11. 02, p = .000), religion(F=2.96, p=.033), occupation(F=6.91, p=.000), living family status(F=13.07, p=.000), living family number(F=11.74, p=.000), monthly pocket money(F=18.79, p=.000), the source of pocket money (F=7.18, p=.000), and the length of residence(F=9.79, p=.000). 3. Health Promotion Lifestyle Profiles was significantly predicted by monthly pocket money($r^2$ change =0. 188, p=.000), sex($r^2$ change= 0.066, p= .000), the length of residence($r^2$ change = 0.059, p = .000), the source of pocket money($r^2$ change=0.036, p= .000), age ($r^2$ change=0.018, p=.000). These variables showed a positive correlation with health promotion lifestyle profiles of the Korean elderly in Japan. These variables explained 36.7% of the variance of Health Promotion Lifestyle Profiles. On the basis of the above findings, Health Promotion Lifestyle Profiles programs for Korean elderly in Japan needs be to developed with Japanese social-culture perspectives and needs to develop an intervention method to improve Health Promotion Lifestyle Profiles. It is also suggested that further research is required.
