  • Reactive oxygen species(ROS) are produced at a high rate continuously as a by-product of aerobic metabolism. Several lines of evidence provided that ROS appears to cause to develop aging and various diseases. High level of hyaluronic acid with decreased molecular weight has been detected in patients with inflammatory diseases including rheumatoid arthritis. Hyaluronidase is an endohexosaminidase that initiates the degradation of hyaluronic acid with high molecular weight. Prunus persica Batsch var. davidiana Maximowicz has been known as a korean folk medicine for treatment of neuritis and rheumatism. (omitted)

  • In this essay, following final conclusions have been drawn by analyzing medical ideology and research system of Yi cheon in Yi hak yip mun("醫學入門"). Firstly, even though the existing medical history researchers are not noting the system of Yi-cheon's medical ideology, this essay has proved the man as a doctor who succeeded the (main system) based on the content of Yi-hak-yip-mun("醫學入門") by Ju-Dan-Gae(朱丹溪). The outline of this proof is as follows. 1. Those doctors who had actively researched in Myung era(明代), were basically taking over the medical studies and result of Gum-Won era(金元代). However, depending on whose theory is to be followed, the followers are largely divided into two groups of Ju-Dan-Gae Academics(丹溪學派) and On-Boe Academics(溫補學派). In addition, both Ju-Dan-Gae Academics(丹溪學派) and On-Boe Academics(溫補學派) hold contradictory ideologies to that of the main medical system. In Yi-hak-yip-mun("醫學入門"), Yi-cheon(李?) ties The Text of Whang-Jae-Nae-Kyung("黃帝內經"), Jang-Jung-Kyung(張仲景), Yu-Ha-Gun(劉河間), Yi-Dong-Won(李東垣), Ju-Dan-Gae(朱丹溪) into one pedigree. With regard to the main system, he especially marks Ju-Dan-Gae(朱丹溪) for his efforts in gathering various medical theories into a large compilement. 2. When Yi-Cheon(李?) was writing Yi-Hak-Yip-Mun("醫學入門"), he made references to various medical publishings, among those book which he had utilized, books by Ju-Dan-Gae Academics(丹溪學派) had affected him more than anything else in terms of both quality and quantity. 3. Yi-Cheon(李?)'s "Congested Phlegm Theory(痰鬱論)" had succeeded "Congested Phlegm Theory(痰鬱論) of Ju-Dan-Gae Academics(丹溪學派). His Yi-Hak-Yip-Mun("醫學入門"), carries a more complete form of "Congested Phlegm Theroy(痰鬱論) which was made into a more systemic and widely applicable method which was by Ju-Dan-Gae Academics(丹溪學派). Secondly, Yi-Hak-Yip-Mun("醫學入門"), is a medical book which was written in the process of systemic reorganization of medical theories of various academic parties in Myung 명 era. Since this process was hearing its completion in the period of Yi-Cheon(李?), he chose specific ways of reshuffling, whilst seeking ways to efficiently utilizing existing medical information . He provided a standard to specific ways. He rearranged the existing medical theories based upon these standards. He also contributed to clinical medicine by providing description of symptoms focused upon the symptoms differentiated In Conclusion, Yi-Hak-Yip-Mun("醫學入門") holds systematic medical information which was developed by Ju-Dan-Gae Academics(丹溪學派). Also, Yi-Cheon(李?) uniformly classified the clinical experiences of existing Ju-Dan-Gae Academics(丹溪學派). He had contributed in the clinical use of Ju-Dan-Gae Academic(丹溪學派)'s clinical experience by providing main points from differentiation of symptoms.

  • Ground beetle fauna of Wangpi-cheon watershed in Yeongyang-gun to Uljin-gun, Gyeongsangbuk-do was investigated from May to October in 2012. Ground beetles were collected by pitfall trapping. A total of 38 species of 20 genera belonging to 8 subfamilies were identified from 2,486 collected ground beetles. Species richness was high in Pterostichinae (16 species), Carabinae (8 species), Harpalinae (5 species), Callistinae (3 species), Nebriinae (3 species) and others (1 species). Dominant species were Synuchus cycloderus (1,025 individuals) and Aulonocarabus seishinensis seishinensis (332 individuals), Pristosia vigil (133 individuals), and Coptolabrus smaragdinus branickii (117 individuals) in order. Monthly changes in abundance of upper dominante genera Pterostichus, Aulonocarabus, Coptolabrus species and Synuchus, Pristosia, Colpodes species showed that the former had the highest number in August whereas the latter increased in June and September. The genus Pterostichus species were preferred in deciduous forest in Wangpi-cheon watershed, while the genus Synuchus species were collected in mixes forest adjacent to farmland and recreation facilities and the genera Chlaenius, Harpalus species were collected in mixes forest adjacent to farmland nearby stream. Non-metric multidimensional scaling (NMDS), ground beetles and sites could be divided into two distinct groups: St. 1, St. 2, St. 3 group and St. 4 group. Some species such as Pterostichus orientalis orientalis, P. vicinus and P. bellatrix were particularly abundant at St. 4.

  • We studied the anti-oxidant and anti-aging activities of Sericinjam Gland Hydrolysate (SJGH) in the human dermal fibroblasts. SJGH effectively defended cell death and ROS generation under high H2O2 in human dermal fibroblasts. Moreover SJGH reduced the expression of SA-${\beta}$-Gal and MMP-1 under low concentration of $H_2O_2$ whereas biosynthesis of procollagen-I was increased. This results demonstrate the anti-oxidant and anti-aging activities of SJGH. SJGH could be a good candidate for anti-aging cosmetics ingredient.

  • Background : The hospital-acquired pneumonia is the most common nosocomial infection. Recently, the Acinetobacter baummannii infections are rapidly increasing, especially the frequency of Multi-drug resistant A. baumannii. Therefore we assessed clinical features and prognosis of patients in the ICU with Multi-drug resistant A. baumannii from the sputum culture using the Clinical Pulmonary Infection Score(CPIS). Method : The medical records of 43 patients with Multi-drug resistant A. baumannii from sputum culture who were suspected had clinically pneumonia and admitted to the ICU from January 2000 to July 2002 were retrospectively analyzed. Results : 19 patients were CPIS greater than 6 and 24 patients were CPIS less than or equal to 6. Mean age for the former was $71{\pm}11$ years old, and the latter was $61{\pm}19$ years old. The mean APACHE II score on admission and on sputum study was not different between two groups($17.4{\pm}5.7$ vs $18.5{\pm}6.1$, p=0.553, $20{\pm}6$ vs $17{\pm}8$, p=0.078). But the mortality rate was 73.7% for the former, and 16.7% for the latter(p<0.001). Conclusion : In ICU patients who had clinically suspected pneumonia with sputum culture positive for Multi-drug resistant A. baumannii, the mortality was significantly higher if CPIS was greater than 6.

  • This study was conducted to improve the postharvest storage techniques of managing and storing seeds, to test qualities and viabilities of the seeds and to examine the germination rate and the protein expression of Achyranthes japonica Nakai. The seeds collected from different areas of Je-Cheon and Gwang-Ju were stored with different temperatures and durations. Two plant growth regulators and two seed priming were treated to investigate their effect on the germination rates and the days required for germination. The weight of one hundred seed collected in Gwang-Ju was heavier than those in Je-Cheon. Seed length collected in Gwang-Ju was also longer about 5.12 mm than those in Je-Cheon about 4.90 mm and seed width was longer in Gwang-Ju than those in Je-Cheon. The rates of seed germination in two different collection areas were higher about 2.9 to 13.0% in Gwang-Ju compared to those in Je-Cheon. Comparing its rates with the storing temperatures and durations, they were not clearly different in between $4^{\circ}C$ and $25^{\circ}C$ and they also were gradually decreased with getting longer storing durations. The germination rates treated by plant growth regulators were higher with $GA_3$ than those with Kinetin. The highest seed germination rate was appeared at 50 ppm of $GA_3$. Comparing its rates with different seed priming, they were relatively higher with $KNO_3$ than those with PEG6000. In protein expression patterns between before the germinating and after the germinating of seeds, more and clear bands were appeared in the seed after the germination compared to those before the germination of seeds, especially 10 ~ 20 kDa. These results showing more and clear bands were more clearly appeared in Gwang-Ju compared to Je-Cheon. Comparing the protein expression with plant growth regulators and seed primings, $GA_3$ was better expression than those with Kinetin and $KNO_3$ was better than those with PEG6000. More and clear bands were closely related to the germination rates of seeds and more detailed studies would be required.
