The purpose of this study was to investigate the acute (4 hours) and repeated-dose (6 hours a day, 5 days a week, 4 weeks) toxic effects of I -hexene on Sprague- Dawley (SD) rats which were treated by inhalation. The results were as follows; I. The median lethal concentration (LC_(50)) was estimated 52,694 ppm (confidence limit 95%; 49,494~55,447 ppm) in acute inhalation. Abnormal clinical signs related to the l-Hexene were not observed with the acute inhalation dose. Gross findings of necropsy revealed on evidence of specific toxicity related to the 1-hexene, II. By repeated inhalation exposure the body weight of male were more or less reduced by the dose of 2,500 ppm and 5,000 ppm compared with control group. However there were no significant variation hematology and blood biochemistry for the exposed rats compared with the control rats. Abnormal clinical signs and gross findings of necropsy related to the 1-hexene were not shown. In conclusion when we exposed I-hexene to SD rats for 4 weeks, 5 days per week, 6 hours per day, the Lowest observed effect level (LOEL) was over 2,500 ppm and Non observed effect level (NOEL) was below 500 ppm.

Exarticulation includes all cases in which the tooth has been totally displaced out of its socket. The main etilogies in the permanent dentition are direct blows and traffic accident, while in the primary dentition are fall-downs. The prognosis of tooth which has been recieved endodontic treatment after replantation is better than received endodontic treatment before replantation. Ca(OH)₂as a initial canal filling material diminishes undesirable replacement root resorption, so in the cases of compelted and uncompleted root formation, the pulp is extirpated and then a Ca(OH)₂dressing is placed until optimal stage for final canal filling with gutta percha cones. Storage media and storage period of avulsed tooth is very important things for prognosis after replantation. A strong relationship has been found between dry storage or storage in non physiologic media (c.g tapwater) and root resorption. Physiologic saline and/or fresh milk is one of the best storage media.

In this study, uptake and translocation of 2,4,6-trinitrotoluene(ThT) by plant in a hydroponic culture was quantified with two indigenous plant species, Aeschynomene indica and Abutilon avicennae on various initial concentrations of TNT ranging from 20 to 80 ㎎TNT/L. Experiments were sterilized to exclude the activity of microorganisms and conducted in duplicate. Weight loss of two plant species in added TNT culture media was higher than in control. At over 20㎎TNT/L, there appeared to be phytotoxicity from TNT as indicated by severe yellow-chlorosis and increase of falling leaves. TNT removal rate normalized(K) to the plant fresh weight of Abutilon avicennae and Aeschynomene indica was that the higher TNT concentrations resulted in lower TNT removal rate normalized(K) to the plant fresh weight. Approximately 96% of the TNT in viable microflora-hydroponic culture was removed after 96h of the experiments.

<목적> 간세포암으로 인한 간외담관폐쇄는 간세포암의 1∼5% 정도에서 관찰되는 비교적 드문 병변이다. 이러한 병변은 수술적 절제가 가능한 경우가 많아(?) 수술전 진단이 중요하나 지금까지의 영상진단 방법으로는 간외담관암과의 감별이 어려웠다. 이에 연자 등은 간외담관협착으로 유도선하 관강내 세경초음파검사(intraductal US, 이하 IDUS)를 시행한 환자 중 간세포암으로 인한 간외담관폐쇄 소견을 보인 환자들을 후향적으로 조사하여 IDUS상 특징적인

Distribution patterns of two pine sawyer species (Monochamus alternatus which is the main vector insect and M. saltuarius which is the potential insect vector of the pine wood nematode) were investigated in Korea. The data were collected at 89 study sites which were chosen to cover the whole region of South Korea. The selected pine trees were killed in early April and left for I year in the pine stands to be egg-laid by the pine sawyers. Emergence of the beetles from the dead pine trees was checked from early April to late July. M. saltuarius was the most abundant in the mid to northern areas of South Korea, whereas M. alternatus in Jeju-do, southernmost island of Korea. Considering temperature distribution patterns in areas where the two species occur, their thermal distribution boundary may be formed around $13.2^{\circ}C$ of annual mean temperature. The hypothesized distribution map of the two Monochamus species under the invasion of pine wilt disease is suggested on the base of thermal distribution of Korean peninsula.
