In order to facilitate the molecular characterization of the Herpes simplex Virus types 1 and types 2 genome DNAs, a gene library of cloned restriction frtgments have been produced. The Vero cells were infected with HSV-1 and HSV-2. 48 hours after infection, the infected cells Ivere Iysed, and multinucleated giant cells were observed approximately at seventy-two hours postinfection. The multiplication of HSV-1 and HSV-2 was observed in Vero cells using electromicroscopy. The nucleocapsids in nuclei were obseryed, and the assembled virions were budded out through the vacuole, and the virions were released from the cells. HSV-1 and HSV-2 was analyzed by digestion of their genome DANs with restriction ensymes. HSV-1 and HSV-2 genome DNAs were digested with BarnHI, Bgfl respectively. The BarnHI rlestriction fragments of HSV-1 and HSV-2 genome DNAs were twenty-seven fragments and thair molecular sizes were ranging $0.70{\sim}15.08$, $4.4{\sim}31.0$ tilobases. The BglII restriction fragments of HSV-1 and HSV-2 genome DNAs were sixteen, eighteen fragments and thair molecular sizes were ranging $4.8{\sim}30.0$, $1.2{\sim}25.0$ kilobases. And then BglII restriction frgments were cloned in Escherichia coli(E.coil) using the plasmid vector pBacPAK9.

Herpes simplex viruses(HSV) are one of the most common infectious virus of man. Though chemotherapies and antibiotics against HSV have been developed in many countries, but anti-HSV agents were not satisfactory to mankind by their toxic reaction and side effects. In order to search for anti-HSV agents from Korean traditional prescriptions, we extended the number of specimens. Both methanol extract and boilling water extract of the Korean traditional prescriptions were screened to detect anti-HSV activities by MTT assay. Korean traditional prescriptions showing anti-HSV activities as methanl extracts were Paekyopsan, Chesupwilyungtang, Yongdamsagantang, and prescription 11. Four methanol extracts showing anti-HSV activities were freationated by hexane and their efficacies were tested. Hexane freationations of Paekyopsan, Chesupwilyungtang, and prescription 11 showed in anti-HSV activities both haxane and methanol fractionation.

향약집성방 및 동의보감등 한의학 서적을 기초로 하여 선택한 탕제 45종과 단미제 80종의 메탄올과 열수추출물을 가지고 MTT assay를 실시하여 항Herpes simplex virus-1 (HSV-1)에 대한 활성을 조사하였다. 열수추출 탕제 45종 중 백사전방, 현람방I, 현람방II, 반천청방 4종에서 항 HSV-1 활성을 나타냈고, 이들의 SI (selective index)값은 $2.1{\pm}0.5$에서 $11.8{\pm}2.2$ 범위의 값을 가졌으며 메탄올추출 탕제 45종 중에서는 단치시호탕III, 반천청방, 정향울금방, 대황오배자고, 홍인락삼등방, 호장해독탕에서 활성을 보였고 이들의 SI값은 $1.7{\pm}0.2$에서 $10.5{\pm}3.1$ 범위의 값을 나타냈다. 열수추출 단미제 중계지, 관중, 구인분, 대황, 자화지정, 포공영, 호장근, 황백등 8종에서 항 HSV-1 활성이 나타났고, 이들의 SI값은 $1.6{\pm}0.1$에서 $10.2{\pm}0.7$ 범위의 값을 가졌으며 메탄올추출 탕제 중에서는 계지, 목방기, 상지, 호장근에서 활성을 보였고 이들의 SI 값은 $2.9{\pm}1.5$에서 $9.3{\pm}0.5$ 범위의 값을 나타내었다. 처방제 중 반천청방은 열수추출물과 메탄올 추출물 모두에서 항바이러스 활성을 나타냈고, 단미제 중 계지와 호장근도 열수와 메탄올 추출물 모두에서 항바이러스 활성을 보였다. 이들 탕제 및 단미제는 분획 및 분석실험을 실시하여 활성성분을 추적하고 있다. In order to search for anti-Herpes simplex virus (HSV) type-1 agents from Korean medicinal herbs and Korean traditional prescriptions (herb complexes), we selected 80 medicinal herbs and 45 prescriptions, based on a review of the Korean traditional medicine books. Both methanol extracts and boiling-water extracts were tested by means of the MTT assay (tetrazolium based colorimetric assay). Ten of the 125 methanol extracts: CM-11, CM-18, CM-19, CM-21, CM-22, CM-39, MM-3, MM-18, MM-29, MM-73 (see explanation of nomenclature below), showed efficacy against HSV-1. Twelve of the water extracts: CW-2, CW-3-I, CW-3-II, CW-18, MW-3, MW-5 MW-6, MW-12, MW-47, MW-69, MW-73 and MW-79 were active. #3 (individual herb) and #73 (individual herb) were interesting because both water and methanol extracts were active. Especially, #3 is a part of composition of Hong-il-$laksamd{\check{u}}ngbang$ and Hojanghaedokt'ang which have anti-HSV-1 activitives. The SI value of MW-69 and CW-18 was relative high as $10.2{\pm}0.7$ and $11.8{\pm}2.2$. The cytotoxic effect on Vera cells of $Panch'{\check{o}}nch'onch'{\check{o}}ngbang$, Taraxacum platycarpum H. Dahlst. and acycloguanosine was determined by MTT assay. Water extracts of $Panch'{\check{o}}nch'onch'{\check{o}}ngbang$ (prescription) and Taraxacum platycarpum H. Dahlst. showed very weak cytotoxic effects on Vero cells at > $100\;{\mu}g/ml$ but acycloguanosine showed strang cytotoxic effects on Vera cells at > $100\;{\mu}g/ml$. As a result, #3, #73, MW-69 and CW-18 are considered as potentially useful for anti-HSV-1 agent and will be the focus of further research. Abbreviations: CM - methanol extracts of traditional prescriptions; CW - water extracts of traditional prescriptions; MM - methanol extracts of individual herbs; MW - water extracts of individual herbs.

Ti과 Si의 비가 서로 다른 종류의 타 을 $Ar/N_2$의 혼합기체를 사용하여 rf magnetron sputtering방법으로 증착된 Ti-Si-N박막의 증착특성에 대해 연구하였다. Ti-Si-N박막의 조성과 증착률은 각 타 Ti/Si의 비율과 증착시의 질소기체의 유량에 따라 크게 변하였다. 이것은 Ti과 Si의 nitriding 정도의 차이로 인한 서로 다른 sputter yield에 의한 것으로 나타났다. Si이 비교적 적게 포함된 Ti-Si-N박막은 증착시부터 박막내 TiN의 결정화가 일어났으며, 낮은 비저항을 나타내었다. N의 함량의 증가는 박막의 밀도와 압축응력을 증가시켜 Ti-Si-N박막의 확산방지 능력에 큰 영향을 미치는 인자로 나타났다. 본 연구에서 $N_2$의 유략과 타 의 Ti/Si비율을 조절함으로써 효율적인 확산방지막인 Ti-Si-N 박막의 공정조건을 확립할 수 있었다. 박막의 공정조건을 확립할 수 있었다. We have investigated the deposition characteristics of Ti-Si-N films obtained by rf magnetron sputtering with ratios of Ti/Si targets in an $Ar/N_2$ gas mixture. The growth rate and stoichiometry dependence of the Ti-Si-N films on the ratio of Ti/Si and $N_2$ flow rate ratio were found to be due to the different nitriding rate of Ti and Si targets. Additionally, their different sputtering yield of nitrified Ti and Si make a reason as well. Lowering Si content in the film favored the formation of crystalline TiN, leading to the low resistivity. Increasing N content led to the Ti-Si-N films having a higher density and compressive stress, suggesting that the N content in the film is one of the most important factors determining the diffusion barrier characteristics. In the current work, the optimum process conditions for the formation of efficient diffusion barrier of Ti-Si-N film has successfully obtained by manipulating the Ti/Si ratio of target and $N_2$ flow rate ratio.

In order to search for anti-HSV agents from natural complex products, we extended the number of specimens. Both methanol extract and boiling water extract of the natural complex products were screened to detect anti-HSV activity by MTT assay. Anti-HSV activities of thirteen natural complex products extracted by methanol and boiling water were screened. Three of 13 natural complex products extracted by methanol showed efficacy against HSV. Natural complex products showing anti-HSV activities as methanol extracts were No.3, 6, 11 and their Sl were 323.809, 2811.041 and 708.20. As water boiling extracts, No.8 and No.11 have displayed Sl of 16.45 and 60.39 respectively. Especially anti-HSV activities of natural complex products extracted by methanol No.6 was stronger than other ones.

Obesity is caused by imbalance of energy intake and expense. If energy intake is more than its expenditure, body does fat accumulation and affects body weight. It can be fetal disease although obesity is not disease in itself. Central regulatary system is affected by many neurotransmitters regulating .food intake in brain. Hypothalamus was known as one of food intake regulation in CNS. In order to investigate gene expression difference in hypothalamus by different nutrient, we used C57/BL6 control mouse and db-/db- mouse. They divided each of two group with mouse, and fed control diet and high-fat diet for 4 weeks. Each of control and high-fat diet contained 11.7% and 59.7% fat, respectively. Then we performed microarray assay with them. We compared among changed genes in hypothalamus region. In the results, we observed that increased genes were more than decreased genes. Although hypothalamus size of db-/db- mouse is smaller than that of C57/BL6, more genes were affected in db-/db- mouse. In this study, many genes are affected by nutrient in hypothalamus region.

In the course of our search for anti-Herpes simplex virus type I (HSV 1) substances from natural sources, we screened crude drugs for their antiviral activity using SRB assay. The methanol extract from herb of Brassica rapa (Cruciferae) was found to inhibit HSV-1. Though bioassay-directed fractionation of the extract, anti-HSV-1 agent was isolated by chromatographic separation using Amberlite XAD-4 and Sephadex LH-20. The structure of compound I was elucidated by spectral means including 1H-1H COSY, HMQC and HMBC to be isorhamnetin 3-O-beta-D-glucopyranoside (compound I). Compound I was active against HSV-1 with the 50% effective concentration of O.42mg/ml and the 50% cytotoxicity of 5.0mg/ml.
