Objectives : The aim of the study is to investigate the effects of moxibustion on the pain behavior and expression of TRPM8 in the dorsal root ganglion(DRG) in the rat model of ambient cold(AC) exposed osteoarthritis(OA). Methods : OA was induced by the injection of $50{\mu}l$ of 2% monosodium iodoacetate(MIA) into the knee joint cavity. To examine the level of pain, weight bearing forces(WBFs) of affected limb was measured. For the AC exposure, the animals were housed in 6 h/day at $4^{\circ}C$ for 14 days after MIA injection. Moxibustion treatment was performed at EX-LE4 and EX-LE5 with 5 cons(1, 7 or 10 mg) per day for 13 days from 5 days after MIA injection. The expressions of TRPM8 in DRG were measured by western blotting analysis. Results : The WBFs of MIA-AC group were decreased significantly compared to MIA group at 2, 3, 6, 7, 8 and 9 days after arthritis induction. After the first 6 h-AC exposure, expressions of TRPM8 in MIA-AC group were increased significantly compared to those of naive group. After moxibustion treatment, only the WBFs of 7 mg treated group were restored significantly. Moreover, the over-expressions of TRPM8 were attenuated by the moxibustion treatment in AC exposed rats. Conclusions : The data suggest that AC can increase arthritic knee pain via up-regulated TRPM8 and moxibustion treatment improve the arthritic pain via modulation of TRPM8 expression in DRG in the rat model of AC exposed MIA induced arthritis.

Objectives : The studies on variation in diagnosis on the neck and nuchal pain has not been done thoroughly as we can use it in clinical practice of these days. For this reason, I examined the variation in diagnosis mentioned in the classics of Oriental Medicine as the preceding study on standardization of variation in diagnosis on neck and nuchal pain. Methods : I gathered the twenty kinds of classics of Oriental Medicine that were computerized, the textbooks on Oriental Medicine which are being used these days, and the theses on current clinical research. After gathering these data, I analyzed these according to the variation in diagnosis. Results : The classics of Oriental Medicine on the neck and nuchal pain mentioned very much about the neck and nuchal pain occurred by the pathogenic factor of Wind, Cold, and Dampness, disharmony created by deficiency of Liver and Kidney, and pathogenic state of Meridians of Taiyang. According to the texts of these days, the differentiation of syndromes can be divided into four kinds of items such as Wind-Cold pathogen, Wind-Dampness pathogen, Phelgm-Heat, and disharmony between Qi and Blood. The theses of these days rarely mentioned about variation in diagnosis on the neck and nuchal pain. Conclusions : The differentiation of syndromes on the neck and nuchal pain can be divided into four kinds items as affection by exopathogen like Wind, Cold, Dampness, Heat, and so on, stagnation of Qi and the coagulation blood, deficient syndrome of Liver and Kidney, and deficient syndrome of Qi and Blood.

The purpose of this paper is to derive the features of cold damage clinical medicine during the early days of the Chosun(朝鮮) period by analyzing discussions on cold damage published in the official medical book of the Chosun period, Compendium of Prescription from the Countryside(鄕藥集成方, CPC). Cold damage was one of the typical diseases in East Asia where there was constant seeking of the utilization of prescriptions, ways of preparations, and awareness regarding cold damage as shown in Zhang, Zhongjing(張仲景)'s Treatise on Cold Damage Disease(傷寒論, TCDD) below. Traditional Korean medicine which possessed the medical universality of East Asia also was no exception and through an analysis of the part on cold damage in CPC, it is expected that medical features of cold damage in Korea passed down from the Koryo(高麗) Dynasty to the early Chosun period will be revealed. For this, first there needs to be an organization of past discussions on cold damage surrounding the existence of infection and after checking the issues, exploring which of the writings related to TCDD and editions are being utilized through an analysis on citing literature of Cold Damage Disease Literature(傷寒門) and Heat Pathogen Disease Literature(熱病門) which have developed discussions on cold damage in CPC. In addition, by comparing Peaceful Holy Benevolent Prescription(太平聖惠方, PHBP) and Complete Record of Sacred Benevolence(聖濟總錄, CRSB), known to have greatly influenced CPC and Cold Damage Literature and Heat Pathogen Disease Literature, features of form and content used by CPC were analyzed. Features of form were examined through pattern of organization and number of citing literature were examined and for features of content, cold damage infection, classification, syndrome differentiation method, and utilization of materia medica among prescriptions were examined. Discussions on cold damage as being uninfectious as stated in Treatise on the Pathogenesis and Manifestations of All Diseases(諸病源候論) unlike pestilence, epidemic pathogen(時氣), warm pathogen disease(溫病), and heat pathogen disease were excluded in PHBP. PHBP opened the possibility of cold damage infection and later writings, CRSB and CPC also follow this. As a result of analyzing citing literature of the part on cold damage in CPC, it is uncertain which edition of TCDD is being utilized; however, the most distinctive feature was that Classified Emergency Materia Medica(證類本草) and not writings specializing in cold damage are in use. In general, although CPC in terms of form is similar to CRSB, content creation predominantly depended on PHBP. More specifically; first, in terms of the existence of cold damage infection, arguments of PHBP and CRSB are maintained. Second, in terms of cold damage classification, although CRSB is followed, heat pathogen disease is classified separately developing PHBP as is. Third, in terms of method, as Book of Keep Healthy(南陽活人書) and CRSB compiled in later times are cited, it is deemed that arguments were raised to a certain extent regarding six-meridian syndrome differentiation(六經辨證). Fourth, although the majority of utilized materia medica among cold damage prescriptions utilize Materia Medica from the Countryside(鄕藥本草) in CPC and materia medica from Korean Peninsula, this is due to the desire for the compilation performance of CPC to be propagated to ordinary citizens and not the ruling class. CPC as the official medical book compiled in the early days of the Chosun period was greatly influenced by the Song(宋) Dynasty's medical books, PHBP and CRSB shows that cold damage medicine in the early Chosun Period indeed possesses the medical universality of East Asia. Furthermore, the features of published medical theory and prescriptions reveal the existence of the cold damage medical tradition of the Chosun period serving as clues for cold damage research tradition among Korea's medical history.

An anomalous cold-weather period occurred during January 2011 in East Asia, and this study investigates the event by focusing on the blocking phenomena formed at Northeastern Asia. The area of cold weather is determined to represent the characteristic features of abnormal cold temperature. The 2010/11 winter is divided into three periods P1, P2 (cold period), and P3. For the cold area ($30-50^{\circ}N$, $115-135^{\circ}E$) the corresponding cold period P2 is determined to be 39 days from 23 December 2010 through 30 January 2011. During P1 and P3 temperature anomalies from the climatological mean are small with large standard deviation compared to those of P2, which has large negative anomaly and small standard deviation. The period P2 is dominated by blocking, which was determined by distributions of 500-hPa geopotential height and potential temperature on the 2 PVU surface. Correlation-coefficient analyses show that during P2 the temperature in the cold area is related with pressure of Northeastern Asia, while the temperature during P1 and P3 is related with pressure of Northwest of Korea. Also, during P1 and P3 the temperature pattern shows eastward propagation, but during P2, a stationary pattern. All the observations imply that, during the cold period P2, the temperature in the cold area is related with blocking in Northeastern Asia. During P1 and P3 temperature pattern is related with 500-hPa geopotential height in Siberia, and this relationship is also observed in the climatological mean state.

This study reports the relationship between life-style and physical, mental health status in college students. The questionnaire survey was carried out from September to October, 1991. The questionnaire included life-style, physical health condition centered on unhealthy habits and complaints about physical symptoms, and mental condition which was assessed by Zung's self-rating depression scale(SDS). Days absent from school during the last year in males(3.6) were significantly more than those in females (1.0). Days catching the common cold were more in females than in males. The amount of complaints and the SDS score were significantly higher in females than in males. In the relationship between physical and mental health status and individual health habits, abscence-days from school significantly correlated with regular life, snacking, physical exercise, smoking, drinking. The amount of complaints and the SDS score were significantly associated with regular life, regular meal-time, eating breakfast, nutritional balance and physical exercise. In the relationship between health practice index to health status, the group having good habits showed significantly less days catching the common cold, less complaints, less SDS score and less amount of stress. It was also shown that life-style correlated with physical and mental health status.

This study was conducted to compare differences in fruit quality by harvest time of 'Fuji' apple fruit that was frozen on tree by unusual low temperature in that air temperature was under $-3.5^{\circ}C$ for 7 hours. Fruits were harvested at 1 day before, and 2 days and 6 days after freezing damage, respectively. Harvest's soluble solid contents in all treatments was over $14^{\circ}Bx$. Firmness and titratable acidity of fruit harvested after freezing damage was lower than those of fruit harvested before freezing damage. During cold storage, ethylene production of fruit harvested after freezing damage was higher than that of fruit harvested before freezing damage. The reduction in the level of fruit quality during cold storage of fruit harvested after freezing damage was more serious than that of fruit harvested before freezing damage. The reduction of fruit quality during subsequent ambient temperature for 1 week after cold storage of fruit harvested after freezing damage was higher than that of fruit harvested before freezing damage. In comparison of treatments that were harvested at different times after freezing damage, ethylene production and reduction in the level of fruit quality until 8 weeks of cold storage of fruit harvested at 6 days after freezing damage was lower than that of fruit harvested at 2 days after freezing damage. However, this difference by harvest time after freezing damage disappeared after 8 weeks of cold storage. Incidence of flesh browning was not affected by freezing at air temperature under $-3.5^{\circ}C$ for 7 hours.

Effects of harvest date, number of the leaves remained on stump after flower cutting, duration of cold treatment on the growth and flowering of L. elegans 'Connecticut King' bulb were tested. Shoot emerging rate increased over 90% by delayed cold treatment, late harvesting time and more leaves remained. Flowering rate increased over 90% when conducted cold treatment of 90 days to the premature bulb at flowering date, the bulb matured for 50 days with 10 leaves and the bulb matured for over 30 days with 20 leaves, and when conducted cold treatment of 50 days to the bulb matured for over 30 days with all leaves. Delayed cold treatment duration shortened days needed to shoot emergence and flowering. Especially days to flower of the premature bulb at flowering date were the shortest of all treatments, and can be flowered within 100 days after planting. In generally, plant height, number of flowers per plant and stem diameter generally increased by longer bulb maturing period after flower cuting, and the premature bulb harvested at flowering date showed poor growing and flowering responses. But, if used the larger size bulb, it is believed that the prematured bulb can be forced to flower normally in current year without bulb maturing period.

To clarify the relationship between ambient water temperature and heading characteristics of rice (Oryza sativa L.), twelve of varieties rice were grown in a cold tolerance screening field where water temperature was controlled by continuous cold water irrigation system to test the cold tolerance of rice. When cold water was continuously irrigated with 5 cm of water depth, the water had stagnated for about three hours, and the water temperature increased gradually from inlet toward outlet in the experimental plot. The fluctuation of water temperature was well synchronized with that of ambient air temperature, and the water temperature near outlet became higher than the air temperature at the vegetative phase, while became lower at the reproductive phase of rice plant community. The leaf development rates on main culm increased by increased water temperature. The rice varities, Fukuhikari, Sangpungbyeo and YR3486-16-2 were more sensitive than the others in the response of leaf development to water temperature. However, Janack and Milyang 42 were comparatively less sensitive to water temperature in leaf development. Janack and Paro -white rices required longer days to develop one leaf on main culm at reproductive phase than at vegetative phase. Varietal difference in days required to develop one leaf on main culm of rice plant was more distinctive at the reproductive phase when water temperature was relatively lower than at the vegetative phase with relatively higher water temperature condition. No difference was found between the growth phases, vegetative and reproductive, in the response of average leaf developmental rates to water temperature under the similar air temperature condition. The estimated average days required to develop one leaf on main culm decreased by 1.3 day by 1$^{\circ}C$ increase in water temperature. Varietal differences in the total number of leaves on main culm depended upon the water temperature, in which the varieties such as Fukuhikari, Gwangmyeon-gbyeo, China 988, and YR3486-16-2 showed increased one leaf by increased water temperature, while Sobaekbyeo, Paro-white, Sangpungbyeo, Pungsanbyeo, Samgangbyeo, and Milyang 42 were kept at the same leaf number regardless of water temperature. However, the total leaf number on main culm and days to heading of Janack increased by increased water temperature. The other varieties showed the shortened days to heading by the increase in water temperature with noticeable varietal differences regardless of the variation in the total number of leaves on main culm.

Objective : We have studied to know effects of Ligigeopoongsan(LGS, 理氣祛風散) on mechanical allodynia, cold allodynia and c-Fos protein expression in the model of neuropathic pain of rats. Methods : The model of neuropathic pain was made by injured tibial nerve and sural never while common peroneal never was maintained. After 2weeks, we performed behavioral test for 7 days to try out mechanical allodynia using von frey filament and cold allodynia using acetone, which are calculated by counting withdrawal response on foot. Rat brains removed and sliced on 8th days. Serial sections were immunohistochemically reacted with polyclonal c-Fos antibody. The numbers of c-Fos protein immunoreactive neurons in the central gray were examined using scion image program. Results : 1. Mechanical allodynia in LGS-2, LGS-3 groups were significantly diminished compared with the control group. 2. Cold allodynia in LGS-3 group was significantly diminished compared with the control group. 3. c-Fos protein expression on the central gray LGS-2, LGS-3 groups were significantly lower than that of control group. conclusions : We have noticed that LGS(理氣祛風散) diminished mechanical and cold allodynia in the model of neuropathic pain compared with the control group. c-Fos protein expression in the central gray of that group was also decreased compared with the control group. Pain control group were LGS was accumulated time goes by. This study can be used as a basic resource on a study and a treatment of pain.
