'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.

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.

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.

Dairy farm efficiency was estimated by data envelopment analysis(DEA) method using farm records surveyed over '94∼'97. The results revealed that dairy farm efficiency was lowered over '94∼'96 and turned upward in 1997 but fell short of the level in 1994. This implies that the various efforts to enhance the dairy farm efficiency in the post Uruguay Round period were not necessary successful. In addition, it turned out that dairy farm efficiency can be better ameliorated by eliminating inefficiency than by scale expansion.

This report studied 31 male patients who were in one hospital in Kwangju or came to a prosthesis clinic and are 15 normal control group to analyze the gait characteristics according to the stump length in the prosthesis users with the unilateral below-knee amputations. The patient group was divided into a short stump subgroup of 13 patients and a long stump subgroup of 18 patients according to the stump length, the control group was randomly sampled from 15 males who have similar age, height and weight to the experimental group. The results of analysis are summarized as follows. 1. There were no significant statistical differences of the general characteristics between patient and control groups and there was no difference of characteristics by patient groups except the mean gait distance a day. 2. Of 33 patients with amputation, 18 patients (57.8%) had phantom pain and 25 cases (80.6%) had neuroma. 3. Gait velocity, stride length of the affected side, step length of the sound side and base support among gait characteristics show a significant difference according to the stump length in the state excluding the effects of other factors (p<05) and the group with long stump showed closer gait characteristics to normal persons than those with short stumps. In conclusion, among the patients of unilateral below-knee amputations, the stump length affects the gait characteristics such as gait velocity, stride length, step and base of support and it is found that as the stump length gets longer, it shows the similar characteristics to gait characteristics of normal persons and long unilateral below-knee amputation can secure better gait characteristics.

The influence of environmental temperature on the acid base balance of frog(Rana Temporaria Chosenica) blood was investigated at 25℃ all the year round. pH of blood was measured by means of Artrup method and Sigaard- Anderson's nomogram using pH meter(Corning) and tonometer. Buffer value, actual bicarbonate concentration and OH^-/H^+ ratio were calculatedd by the measure buffer line, pH and CO2 gas tension which was used(low CO_2 was 4-5% and high C0_2 was 8-9% balanced with 0_2). Results obtained are as follows: 1. Buffer line was shift to the upper and-right side during winter season and the differences was statistically significant. 2. Buffer value was higher during winter season than summer value and the difference was significan (p<0.001). 3. The actual blood pH was 7.42±0.01 in September and 7.78±0.03 in January. Generally the pH was higher during winter season than that of summer. The difference between two seasons was statistically significant(p<0.05). 4. The blood PCO_2 value has a seasonal changes with low PC0_2 during winter season and the differences were statistically significant. 5. The plasma bicarbonate concentration was 17.00±1.07mM/L in September and the value were decreased with cold weather of 12.33±1.29mM/L in January. Seasonal changes were significantly different(p<0.05). It is concluded from this findings that the acid-base changes of blood in frog were related to the temperature of living habitat and the corresponding changes in the tissue energy store and buffers.

Orostachys malacophyllus F. is a kind of ,Chinese medicine to grow on the tiled roof of the house or on the rock of the mountain. The chemical compositions and actions have not been reported, but, sometimes, it was used as a folk remedy for the treatment of cancerous diseases. This study was attempted to investigate the effects of water fraction separated from alcohol extract of Orostachys malacophyllus F. on the contractilities of cardiac and intestinal muscles comparing with those of the water extract. The muscles used for this study were the ventricular muscle of turtle and the intestinal muscle of mouse, and their contractilities were represented as a change of the muscle tension detected by myograph. The results were summarized as follows: 1. The water fraction decreased the contractility of ventricular muscle, and increased the intestinal contractility. But the water extract was observed the opposite effects on the contractility of each muscle. 2. Sympathetic or parasympathetic blocker and alpha-or beta-blocker had no effect on the decreased or increased contractility of each muscle. 3. Calcium antagonist(verapamil) inhibited significantly the contractility in the case of the water fraction to the intestinal muscle and the water extract to the ventricular muscle. From the above results, it was suggested that the action of water fraction or the water extact affected to calcium transport: release into the sarcoplasmic fluid or active influx into the sarcoplasmic reticulum in the case of the cardiac muscle, and release from ECF or cisternae of reticulum into the muscle cell in the smooth muscle.
