Dendropanax trifidus belonging to the family Araliaceae, is a warm-temperate evergreen tree distributed in Jeju Island, Bogil Island, Geomun Island, Geoje Island, Wando, and Haenam in Korea. In June 2021, a root rot disease in which branches of Dendropanax trifidus seedlings turned brown and shrunk was discovered at the seedling cultivation facility in Naju-si, Republic of Korea. To identify the root rot fungus, three strains were isolated from the diseased tissues of seedlings and their mycological characteristics were investigated on potato dextrose agar. In addition, a molecular phylogenetic analysis was performed using sequences of the internal transcribed spacer (ITS) region and translation elongation factor 1-α (EF1-α) gene. The fungus was identified as Fusarium oxysporum. For pathogenicity test, the roots of seedlings were immersed in the conidia suspension of the strains and planted. After 20 days inoculation, root rot and browning symptoms were confirmed in the inoculated plants. This is the first report of F. oxysporum on D. trifidus in Korea.

Background : Angiogenesis is the proliferation of a network of blood vessels emanating from pre-existing vessels, supplying nutrients and oxygen and removing waste products. Angiogenesis occurs in a variety of normal physiologic and pathologic conditions and is regulated by a balance of stimulatory and inhibitory angiogenic factors. Excessive angiogenesis should be suppressed. However, if blood supply is insufficient, it should be encouraged. Hyul-Mek(血脈) or Hyul-Rark(血絡), known as blood vessels in western medicine, is deeply related to Chung-Ki-Hyul(精 氣 血). The goal of this study is to review the effects of herbal medicines on angiogenesis that is involved in wound healing and enhancement of blood supply. Methods : We conducted a systematic and comprehensive literature search for the identification, retrieval, and bibliographic management of independent studies to locate information on the topic. A computerized search of the published literature of Korea(KISS, RISS), China(CNKI), Japan(Kampo medicine, etc), and western countries(MEDLINE) was performed, and further supplemented with manual searches of print sources(1999 to 2003). Results : The herbal medicines with angiogenic activity were mainly found among herbs that carry replenish Shin-Cheng(補腎益精), foster Eum and improve the circulation of blood(養陰活血), or warm and circulate Kyung-Rark(溫經通絡). In particular, herbs with improve the circulation of blood and clear blood(活血化瘀) activity contain a significant amount of tannin, saponin, and pyrazine. Conclusion : Replenish Ki-Hyul(補氣血) and circulate Kyung-Rark(通經絡) could contribute to the induction of angiogenesis because various growth factors and proliferation, differentiation, and migration of vascular endothelial cells are involved in angiogenic activity.

Pectobacterium carotovorum subsp. carotovorum (Pcc) causes bacterial soft rot on a wide range of crops worldwide, especially in countries with warm and humid climates. This study was conducted to establish an efficient screening method for resistant cultivars of Chinese cabbage to bacterial soft rot. Resistance degrees of 65 commercial Chinese cabbage cultivars to the Pcc KACC 10225 isolate were investigated. For further study, three Chinse cabbage cultivars (Taebong, Hadaejangkun, CR Alchan) showing different level of resistance to the bacterium were selected. The development of bacterial soft rot on the cultivars was tested according to several conditions such as growth stage of Chinse cabbage seedling, inoculum concentration, and incubation temperature after inoculation. On the basis of the results, we suggest that an efficient screening method for resistant Chinses cabbage to Pcc is to inoculate twenty one-day-old seedlings with a bacterial suspension of Pcc at a concentration of 1×10⁷ cfu/ml, and to incubate the plants in a dew chamber at 25℃ for 24 hr and then to cultivate in a growth room at 25℃ and 80% relative humidity with 12-hr light per day.

This study is aimed at developing a cardiac rehabilitation program and enlightening the effects of the program on patient's health behavior compliance, cardiovascular functional capacity, and quality of life. Using a quasi-experimental approach the nonequivalent control group pretest - posttest design was accepted for this study. The subjects of this study consisted of 55 patients with ischemic heart disease at the Cardiac Center of 'G' Hospital located in Inchon from May 1, 1998 to April 30, 1999. The patients were divided into two groups: the experimental group, which participated in the cardiac program with 30 patients and 25 patients of a control group were not involved in the program. There were two phases in the cardiac rehabilitation program: the first phase was a team approach education. It focused on reducing the risk of ischemic heart problems. The second phase was individual training by using a home based exercise program, which was comprised of 8 weeks, three sessions per week, 40-60 minutes per session, and followed by consultation. Every session involved 20-40 minutes of aerobic exercise at 40-60% of heart rate reserve, 11∼13 RPE and 10 minutes of warm-up and 10 minutes of cool-down exercises. The experimental tools for the study were the health behavior compliance scale developed by Lee, Yoon-hee (1992), and quality of life scale developed by McGirr et al.(1990). RPPsubmax were measured by the treadmill. The collected data was processed by SPSS and analyzed by χ²test and t-test. The results of this study were as follows: 1. The health behavior compliance in experimental group was significantly increased (t=5.091, p=.000) when compared to the control group. 2. RPPsubmax also decreased significantly in the experimental group when compared to the control group(t=-2.109, p=.040). 3. The quality of life significantly improved in the experimental group (t=3.853, p=.000) as compared to the control group. As the above results of this study revealed, the effectiveness of the cardiac rehabilitation program of the study was confirmed. It increased the health behavior compliance for reducing the risk of further coronary events, enhanced the cardiovascular functional capacity, and eventually improved the patient's quality of life.

This study searched the philosophical and medical thought of mutual understanding and human body. Mutual understanding is a fundamental problem in all branches of oriental studies. In other words, mutual understanding becomes the existential foundation of heaven-earth-human(三才). So human beings, heaven and the earth can't exist if there is no mutual understanding. It comes out the problem of self-consciousness in philosophy, and qi movement pattern like upward, downward, inward and outward movement in traditional korean medicine. Human beings have mutual understandings with heaven and the earth from a macroscopic standpoint, on the other side the human body from a microscopic standpoint. Qi movement is the mutual understanding and response of qi in human body, so with which the physiological functions and pathologic changes of viscera and bowels comes out. Therefore we want to present how to complete qi movement between viscera-bowels and organs to examine mutual understandings in human body closely. The results was summarized as follows; First, upbearing the clear yang and down bearing the turbid yin of spleen-stomach is main pivot of upward and downward of qi movement, and it is true form of mutual understandings between viscera and bowels, so upward, downward, inward and outward movement of whole viscera and bowels can be controlled by spleen-stomach. Second, by restraining relationships between downward heart fire and upward kidney water, heart fire and kidney water have close communications physiologically and pathologically as upper-lower, yin-yang and water-fire. Third, by restraining relationships between upbearing and effusion of liver and purification and down-sending of lung, liver and lung are outer circles of upward and downward movement, so they have antagonistic functions. Firth, by the relationships between upbearing the clear and down bearing the turbid of spleen-stomach and free coursing of liver, free coursing of liver-gallbladder is the essential requirement that it certify transportation and transformation of spleen-earth, so the disease of liver-gallbladder induce spleen-stomach disease pattern to affect its function of transportation and transformation. Fifth, by spleen and kidney, spleen yang is based on kidney yang, so the weakness of kidney yang can affect the function of transportation and transformation of spleen-stomach as it can't warm spleen earth. Sixth, by homogeny of liver-kidney, essence and blood of liver-kidney and ministerial fire of liver-kidney have mutal generation and limitation physiologically and they mutually are affected in pathologically.

Scz1, an isolate of Sclerotinia homoeocarpa, was recently reported as a novel pathogen responsible for dollar spot disease in Zoysiagrass, a warm season turfgrass. Scz1 possessed different characteristics on mycelial pigment, mycelial affinity and host pathogenecity compared to those of Scb1, a typical isolate, obtained from creeping bentgrass, a cool season turfgrass. In this study, only three isolates, Scz1, Scz2(another analogous isolate of Sclerotinia homoeocarpa from zoysiagrass), and Scb1, were examined at the molecular level using the internal transcribed spacer(ITS) and random amplified polymorphic DNA(RAPD) assays to verify their identification and genetic variation. As a result of ITS assay, partial ITS sequences of three isolates showed 94-97% similarity with a standardized ITS sequence of S. homoeocarpa registered on BLAST. In the analysis of RAPD, range value through similarity matrix was 0.167 between Scz1 and Scb1, 0.139 between Scz2 and Scb1, and 0.713 between Scz1 and Scz2, respectively. Furthermore, tendegram analysis indicated that Scz1 and Scz2, unlike Scb1, were clustered together as accompanying a high genetic similarity. In in vitro fungicide bioassay, $EC_{50}$ value representing the sensitivity degree to propiconazole, a well-known fungicide for dollar spot disease, was 0.012 ${\mu}g/ml$ for Sczl, 0.003 ${\mu}g/ml$ for Scz2, and 0.030 ${\mu}g/ml$ for Scb1. From all data taken, we concluded that both Scz1 and Scz2 belonged to one group of S. homoeocarpa, since they exhibit the same host range and high level of genetic similarity, whereas their chemical competences to a fungicide were different. This study would provide further approach for assessing genetic diversity of S. homoeocarpa isolates as well as characterizing individual isolate against chemical exposure.

The purpose of this study was to find the effects of long-term combined exercise on regional bone mineral density(BMD) and cardiovascular disease(CVD) risk factors in the elderly with osteoporosis(OP). For the purpose, the subjects of this study were separated by two groups with thirty-one elderly women, who the first group was combined exercise group(CEG, n=16) and second group was non exercise group(CON, n=15). The combined exercise program was made up of warm-up (10min), work-out (aerobic; 30~45min/HRR 40~60%, resistance; 1RM * 50-70%, 8-10 * 2set ~ 10-15 * 1set), and cool-down (10min). Exercise group of the inspection have been trained 5 times a week for 1years. The results : At first, the variables of regional BMD were significantly different to pelvis, spine, trunk and T-score in two groups. At second, the variables of CVD risk factors were significantly different to SBP and DBP as well as TC, TG, LDL-C and HDL-C in two groups. As results of these conclusion, this study have positively effect shown that CEG was superior to CON in regional BMD(pelvis, spine, trunk and T-score), blood pressure(SBP, DBP) and plasma lipids(TC, TG, and LDL-C). Especially, the long-term combined exercise was provides a striking overall health quality of life with improving BMD and reduced CVD risk factors in the elderly with OP. In the future, other researches should deal with specific measures that reduction in mortality due to chronic disease and improvement quality of life for the development of programs in multiple researches of osteoporosis and chronic diseases.

Nature of herbs and properties and flavors that were used in the case records were classified and frequency of each nature of herbs were analyzed. Applicable case records were interpreted and suggested prescriptions, pulse feelings, pattern classification were analyzed and described. Results : Among the 5254 case records stated on the complete collection, it is researched that there are 63 case records for the symptom complex of dyspnea as 1.2% of the whole case records, and the case records on the symptom complex of wheezing asthma are 14 as the 0.27% of the total examples. 63 case record examples related with symptom complex of dyspnea were pattern identified and classified. As a result, deficiency syndrome of the Kidney(33 %), deficiency syndrome of the Spleen(26.0%), Wind-Cold(12.3%), phlegm turbidity(12.3%), Heat in the Lung(8.2%), asthenia of the Lung(8.2%) were investigated as above order. 14 case record examples related with wheezing asthma were pattern identified and classified. As a result, phlegm-Heat(26.3%), upper excess and lower deficiency(26.3%), external affections Wind-Cold(15.8%), Dampness-phlegm(10.5%), Lung asthenia(10.5%), Cold phlegm(5.3%), mutual deficiency and detriment of Heart and Kidneys(5.3%) were investigated as above order. Symptom complex of dyspnea has 67.1% of deficiency syndrome, 32.9% of excess syndrome resulting more deficiency syndrome than excess syndrome. Symptom complex of wheezing asthma has 42.1 % of deficiency syndrome and 57.9% of excess syndrome resulting more excess syndrome than deficiency syndrome. In case of symptom complex of dyspnea prescription used in the case record, the order of frequency is as following. Palmijihwang-tang, Bojung-ikgitang, Yungmijihwang-tang, Ijintang, Sojaganggitang, Igongsan. In case of symptom complex of wheezing asthma prescription in the case record, Yungmijihwang-tang, Ohotang, Dodamtang were mostly used. Herbs used in case records of symptom complex of dyspnea are Ginseng Radix, Poria, Glycyrrhizae Radix, Aconiti Iateralis Preparata Radix, Atractylodis Macrocephalae Rhizoma, Dioscoreae Rhizoma, Angelicae Gigantis Radix, Rehmanniae Radix Preparat, Pinelliae Rhizoma, Zingiberis Rhizoma Recens are mostly used. Nature of herb properties used for symptom complex of dyspnea and symptom complex of wheezing asthma are herbs that are warm properties. When the symptom complex of dyspnea and the symptom complex of wheezing asthma were treated. if the patient felt tenderness at Pyesu, doctors conducted pricking blood around the opposite Pyesu or Sipseon acupoint. when the patient didn't have tenderness at Pyesu by soft press, pricking blood was performed both sidees, right and left Pyesu. In case of the treatment of symptom complex of dyspnea and symptom complex of wheezing asthma, when they got treatment, when the symptom complex of disease is severe, a doctor cauterized the opposite Pyesu while the other Pyesu felt tenderness, and decided how the above treatment is performed whether the degree of the symptom compolex of disease is severe or not. In case of the treatment of symptom complex of dyspnea and symptom complex of wheezing asthma, if the person felt tenderness at Pyesu and is caught by the Wind-Cold pathogen, slight acupuncture is treated at relevant Pyesu with Fire needling. When patient with symptom complex of dyspnea and symptom complex of wheezing asthma cannot hawk sputum up from the oral and laryngopharynx, suction method is treated. Conclusion : With this study, actual traditional and clinical pattern identification form and characteristics of symptom complex of dyspnea and symptom complex of wheezing asthma were recognized. Modern case report utilizing in clinical application need to be secured and an incurable disease asthma need to be diagnosed and improvement for treatments have to be searched through other case records.
