황명석,조창희,박종희,Whang, Myung-Suk,Cho, Chang-Hee,Park, Jong-Hee 한국생약학회 2000 생약학회지 Vol.31 No.2

'Ha Go Cho (夏枯草)' is one of the Chinese crude drugs used mainly as a diuretic. With regard to the botanical origin of 'Ha Go Cho', it was reported by Su et al. that those from China were originated from the fruited spica of Prunella vulgaris L. of Labiatae. It was, however, for the herba or spica of Prunella vulgaris L. var. lilacina Nakai from Korea. According to survey of markets in Korea, most of the materials collected in the markets seemed to be originated from Prunella plant, while some seemed to be Thesium plant of Santalaceae. To clarify the botanical origin of 'Ha Go Cho', the anatomical characteristics of Prunella vulgaris L. var. lilacina Nakai and Thesium chinense Turcz. were studied. As a result, it was clarified that some 'Ha Go Cho' from Korea were the herba or spica of Prunella vulgaris var. lilacina, whereas some others were the herba of Thesium chinense.

Chungtaejeon is a traditional tea introduced in the age of the Three States and is the only “Don-cha” culture in the world that survived on the southwestern shore of Korea. To restore Chungtaejeon and to make the tea with consistent quality, the microorganisms involved in traditional type fermentation of Chungtaejeon were isolated, and the tea was prepared with high fermentation ability starters. The sensuous characteristics of Chungtaejeon were also examined. Only Bacilli were found in 3 and 5 year aged Chungtaejeon samples. The Lactobacilli were isolated from properly fermented kimchi and one of them showed high growth capability in media containing green tea extract and also showed strong antagonistic activity against methicillin-resistant Staphylococcus aureus, S. aureus, Salmonella, and E. coli. It was identified and named Lactobacillus plantarum CHO25. Chungtaejeon was fermented with a single starter of L. plantarum CHO25 and with a mixed starter (L. plantarum CHO25, Saccharomyces cerevisiae and Bacillus amyloliquefaciens CHO104). The single fermented sample had the highest cell growth after 5 days of inoculation and the level decreased slowly thereafter. The mixed fermented sample showed strong growth of S. cerevisiae. The highest hunter values were the a value of the single fermented sample and the b value of the mixed sample. The single fermented tea showed the best incense score.

This is to investigate the posibility of home manufacturing of heavy chemical industry machines, such as rotary kiln, crusher, blower, cooler, electrostatic precipitator and weighing feeder of cement plant. It is concluded that even though we can not make all of them (some of them are made now and some others are going to be made in the near future, some of them are made whole and some others are made partially), we can build or export the cement plant by importing the important machines which we can not make now and by substituting them with ours gradually.

Cho, Eun-Sang,Choi, Kun-Ho,Kim, Min-Gyu,Lim, Hoi-Jeong,Yoon, Suk-Ja,,Kang, Byung-Cheol 대한구강악안면방사선학회 2005 Imaging Science in Dentistry Vol.35 No.4

Purpose : This study was aimed to compare skin entrance dose of digital radiography with that of film radiography and to show the dose reduction achievement with digital systems at 11 dental schools in Korea. Materials and Methods : Forty six intraoral radiographic systems in 11 dental schools were included in this study. Digital sensors were used in 33 systems and film was used in 13 systems. Researchers and the volunteer visited 11 dental schools in Korea. Researchers asked the radiologic technician (s) at each school to set the exposure parameters and aiming the x-ray tube for the periapical view of the mandibular molar of the volunteer. The skin entrance doses were measured at the same exposure parameters and distance by the technician for each system with a dosimeter (Multi-O-Meter : Unfors instruments, Billdal, Sweden). Results : The median dose was 491.2 μGy for digital radiography and 1,205.0 μGy for film radiography. The skin entrance dose digital radiography was significantly lower than that of film radiography (p<0.05). Conclusion : Fifty-nine percent skin entrance dose reduction with digital periapical radiography was achieved over the film radiography in Korean dental schools.

Reduced glutathione (GSH) has been reported to be effective in some hepatic disorders and also in protecting the body against a certain toxic agents including ionizing radiation. However, little is known whether GSH is also effective in acute ethanol intoxication. In the present study, an effort was directed to clarify the possible effectiveness of GSH in the state of excessive ethanol ingestion to the point of acute intoxication. The protein, GSH and GSSG (oxidized glutathione) levels of the liver, and the GSH and GSSG levels of the blood as well as hematocrit (Hct) and blood ehtanol concentration were chosen as the parameters of the hepatic or blood metabolism. The healthy and fully matured albino rats of either sex were used, and 1.5㎖ of 50% ethanol per 100gm of body weigilt was given by oral intubation to produce the acute ethanol intoxication (EOH group). GSH in the dose of 5mg per 100gm body weight for three days was intraperitoneally injected either alone (GSH group) or prior to the ethanol intoxication (GSH+EOH group) which was initiated immediately after the last injection of GSH. The rat was sacrificed at 1, 3, 6, 12 and 24 hours in all the group by cutting the carotid arteries and the blood sample was obtained. The liver was immediately excised and placed into an ice-cold saline until ready for use. The protein of the liver was measured by the method of Lowry, et at, GSH level of the liver and blood by Ellman's method and GSSG by the electrolytic reduction method described by Dohan and Woodward. Hematocrit was determined by the conventional microhematocrit method using Adams microhematocrit centrifuge and reader, and the blood ethanol concentration was measured by the method of William, et al. The results obtained were compared with the normal and summarized as follows. The blood ethanol concentration in both EOH and GSH+EOH groups reached the highest level of 712.0±10.9mg% and 668.0±16.Omg%, respectively, at one hr and gradually declined until 24 hrs after the ethanol ingestion, but all the experimental hour showed a significant increase from the normal value of 145.0±12.Omg%. Between GSH+EOH group and EOH group, the former showed a slightly lowered value than the latter, though the difference was not significant. The highest Hct values were obtained at 6th hr and significantly elevated values continued throughtout the experiment in both EOH and GSH+EOH group, but GSH+EOH group showed a lower level of Hct comparing with EOH group. The blood GSH level in GSH group showed elevated value in the first part of the experiment followed by a gradual decline to the normal value of 6.85±0.40μmo1/㎖ at 24 hrs. EOH group, however, showed significantly lower value throughout the experiment with a recovery to the normal virtue at 24th hr. In GSH+EOH group, all the value was higher than in EOH group. The blood GSSG level in GSH group showed higher values at 1-3 hrs with a tendency of recovering to the normal value of 11.90±1.04μmo1/㎖ at 24th hr. Both EOH and GSH+EOH groups showed elevated values throughout the experiment, but GSH+EOH group showed a tendency of higher value than EOH group. The liver protein levels in both EOH and GSH+EOH groups showed significantly elevated values throughout the experiment with a tendency of higher value in GSH+EOH group comparing with EOH group. The liver GSH level in EOH group was significantly decreased comparing with the normal value of 9.2±0.72μmo1/㎖ with the lowest value at 6th hr. In GSH+EOH group, the liver GSH level was generally higher than in EOH group. The liver GSSG level in EOH group showed the highest value at 6 and 12 hrs while GSH+EOH group showed the highest value at 1 and 3 hrs with a tendency of recovering to the normal value of 5.21±0.48μmol/㎖ at 24 hrs. From the above, it may be concluded that the administration of GSH is effective to a certain degree in acute ethanol intoxication.

한국인의 언어의식 : 언어접촉과 관련된 사회언어학적 연구

The present study is an attempt to provide a rough profile of lingustic consciousness, as reflected in the day-to-day use of present-day Korean. The underlying assumption throughout is that the drastic socio-political changes in post-Liberation Korea must have left strong imprints in the popular Korean psyche and that there must be linguistic reflexes for these imprints, The present study does indeed come up with an interesting assortment of linguistic changes attributable to such socio-political changes as ① the coming of democracy and the nuclear family and ② an ever increasing encounter with other dialects and languages. As such, the present study can serve as a basis for a systematic formulation of language policy or for a principled 'purification' of Korean. A 50-item questionnaiare is used for the present study. The 784 respondents range from middle-school students to college graduates and represent both sexes and most of the major dialects of Korean.
