  • Eighteen multiparous and 8 nulliparous cows with cystic ovarian disease (19 having follicular cysts, 7 with luteal cysts) were administered either 3000 I. U. HCG or $300{\mu}g$ LHRH. Ten animals responded satisfactorily leading to normal estrus within a period of 15 to 30 days and subsequent conception. In 8 animals cysts recurred and no effect of treatment was observed in 3 patients. Plasma progesterone concentration was significantly lower in animals having follicular cysts compared to those with luteal cysts.

  • The followings are the results obtained from the investigation of isolation and cultural conditions of a fungus producing antibiotic from humus, spring soil, paddy, field and etc. 1. Among fungi which were capable of antimicrobial sub stance producing at the $45^{\circ}C$, Strain H-3 was selected as test st rain because of its efficiency in antimicrobial substance producing. 2. Strain H-3 was identified as a Aspergullus fumigatus by the mophological properties. 3. The compositions of optimun media for the production of antimicrobial substance were followed;glucose 20g, $NaNO_3$ 3g, $K_2HPO_4$ 1g, $CaCl_2$ 0.5g, $MgSo_4$ 0.5g, $FeSO_4$ 0.005g. 4. Optimum culture conditions were founded to be pH 5.0, $40^{\circ}C$ respectively. 5. The maximum antimicrobial substance producing obtained in this study was showed 14mm of clear zone after 72 hrs incubation under the optimum conditions. 6. AF-c substance was active against Gram-positive, Gram-negative bacteria, and yeast but not mold in its biological properties.

  • This paper presents a compact structure composed of an upper high-impedance transmission line, a middle extended parallel coupled line, and a pair of inter-coupled symmetrical stepped impedance stubs. Detailed investigation into this structure based on an equivalent circuit analysis reveals that this proposed structure exhibits a quasi-elliptic low-pass filtering response with three transmission zeros. Moreover, the positions of the three transmission zeros can be tuned and reallocated flexibly by choosing the proper circuit parameters. Finally, the design concept is validated through the design, fabrication, and measurement of two exemplary low-pass filters (LPFs) with one single unit and two cascaded asymmetric units. The measured results agree well with the simulated results. In addition, in the range of $1.42f_c$ to $7.03f_c$, the fabricated quasi-elliptic LPFs experimentally demonstrate a very wide upper-stopband of 20 dB using a compact size of only $0.0089{\lambda}_g{^2}$, where ${\lambda}_g$ is the guided wavelength of a $50{\Omega}$ transmission line at the central frequency.

  • Physiological effects of Korean black soybean pigment were investigated. Major anthocyanin pigments of Korean black soybean were extracted with 1% HCl for 24 hours at $4^{\circ}C$. Inhibitory effects of angiotensin converting enzyme ($IC_{50}$) were 0.22 mg/mL (Kumjungkong #1), 0.28 mg/mL (Ilpumkumjungkong) and 0.38 mg/mL (Milyang #95). Inhibitory effects xanthine oxidase ($IC_{50}$) were 0.118 mg/mL (Kumjungkong #1), 0.165 mg/mL (Ilpumkumjungkong) and 0.163 mg/mL (Milyang #95). The cPLA2 inhibitory effects ($IC_{50}$) were $19.7\;{\mu}g/mL$, $10.7\;{\mu}g/mL$ and $25.3\;{\mu}g/mL$. The cytotoxic effects of anthocyanins from Milyang #95 were 66.0% against human colon cell line (HT29), 58.2% against human liver cell line (HepG2) and 64.4% against mouse liver cell line (Hepa), respectively.
