  • Ozone effects were studied by plant growth chamber to evaluate the impact of ozone ($O_3$) on the physiology of two hot pepper, Capsicum annuum L., cultivars, 'Dabotab' and 'Buchon'. Forty-day old plants with $5{\sim}7$ leaves were exposed to $O_3$ of <20 and 150 nL/L for 8h/d for 3 days. Net photosynthesis and stomatal conductance were measured and foliar injury was described. Foliar damage due to the treated $O_3$ was different from the varieties. 'Dabotab' was most sensitive to $O_3$ and 'Buchon' was resistant. Symptom of ozone damage on the leaves was bifacial necrosis. Decreases of net photosynthesis by $O_3$ were 56% and 40% on 'Dabotab' and 'Buchon', respectively. Decreases of stomatal conductance by $O_3$ were 66% and 63% on each variety. $O_3$ damage on net photosynthesis was started at the low levels of light on the two hot peppers. In addition, assimilation-internal $CO_2$ concentration curves were not different from the two varieties. In conclusion, $O_3$ closed the stomata and decrease net photosynthesis on hot peppers regardless of the ozone sensitivity on leaf injury, but the difference of ecophysiological responses between the two varieties was not found clearly.

  • Purpose: Various gastrointestinal factors may contribute to maladaptive behavior in children with autism spectrum disorders (ASD). To determine the association between maladaptive behavior in children with ASD and gastrointestinal symptoms such as severity, intestinal microbiota, inflammation, enterocyte damage, permeability and absorption of opioid peptides. Methods: This observational cross-sectional study compared children with ASD to healthy controls, aged 2-10 years. Maladaptive behavior was classified using the Approach Withdrawal Problems Composite subtest of the Pervasive Developmental Disorder Behavior Inventory. Dependent variables were gastrointestinal symptom severity index, fecal calprotectin, urinary D-lactate, urinary lactulose/mannitol excretion, urinary intestinal fatty acids binding protein (I-FABP) and urinary opioid peptide excretion. Results: We did not find a significant difference between children with ASD with severe or mild maladaptive behavior and control subjects for gastrointestinal symptoms, fecal calprotectin, urinary D-lactate, and lactulose/mannitol ratio. Urinary opioid peptide excretion was absent in all children. Children with ASD with severe maladaptive behavior showed significantly higher urinary I-FABP levels compared to those with mild maladaptive behavior (p=0.019) and controls (p=0.015). Conclusion: In our series, maladaptive behavior in ASD children was not associated with gastrointestinal symptoms, intestinal inflammation (no difference in calprotectin), microbiota (no difference in urinary D-lactate) and intestinal permeability (no difference in lactulose/manitol ratio). ASD children with severe maladaptive behavior have significantly more enterocyte damage (increased urinary I-FABP) than ASD children with mild maladaptive behavior and normal children.

  • As the results of investigation, the noise level was between 60 dB and 80 dB in the area of explosion. The residents living within 1 Km would feel uncomfortable. However, hearing loss is not happened by this range. The maximum range that the human can hear is 20,000 Hz and the maximum range that the dog can hear is between 20 Hz and 40,000 Hz. The auditory range for humans to be uncomfortable toward noise is between 1,000 Hz and 2,000 Hz. As the result of this experiment, the auditory range of dog is more wide than of a human. The change of hair cells in the Corti's organ occurred when the dog was exposed to 1,000 Hz at 100 dB for 1 month. Therefore, the structure change of the ear could happen by hearing loss because of noise, but the structure change of hair cells is the worst symptom by hearing loss because of noise.

  • Objectives : "The purpose of this study is to report the effectiveness of Soshiho-tang(小柴胡湯)" on the patient suffered from nausea, retching, vomiting and postprandial fullness. Methods : We diagnosed the symptoms and the signs of the patient as Soshiho-tang syndrome(小柴胡湯證) according to "Treatise on Cold Damage Disease(傷寒論)". We prescribed Soshiho-tang with acupuncture and moxibustion for about 2 weeks. Results : The subjective assessments of the nausea and postprandial fullness had improved. And the frequencies of the retching and vomiting had decreased. Conclusions : We suggest that Soshiho-tang has effectiveness on nausea, retching, vomiting and postprandial fullness in patient diagnosed as Soshiho-tang symptom.

  • Objectives : In acute stage of CVA, many patients experience Bugibultong as a symptom. Daesiho-tang is one of the most useful prescriptions for constipated stroke patients. This study investigated the effects of Daesiho-tang extracts on hypoxic E18 cortical neuroblast. Methods : To evaluate the effect of Daesiho-tang extracts on enuronal death caused by hypocia the neuronal viability and protein expressions of NMDA receptor subunits, ${\alpha}CaMK$ II PDE2 PSD95 densin-180, $eEF-l{\alpha}$ and GFAP were investigated. Results : We guessed that Daesiho-tang extracts worked to protect against cell damage through effecting on the protein expression of PSD(post synatpic density), especially increase of ${\alpha}CaMK$ II, $eEF-l{\alpha}$ PDE2, PSD95 and densin-180 Conclusions : According to the above results, it is supposed that Daesiho-tang is clinically applicable to stroke patients in the acute stage.

  • The diagnosis of juvenile rheumatoid arthritis (JRA) is based on patient's age at disease onset, symptom duration, gender, and clinical manifestations. JRA is of unknown origin, begins under the age of 16, and persists for a minimum of 6 weeks. JRA is categorized into three principal types, systemic, oligoarticular and polyarticular. Infection, other connective tissue diseases, malignancy, trauma, and immunodeficiency are discussed as differential diagnoses for JRA. Because of joint damage, focusing on early diagnosis and intervention, a vigorous initial therapeutic approach must be taken in patients who have poor prognostic factors. A multidisciplinary team approach is also important for the care of patients with JRA.

  • Main tobacco diseases were surveyed on major flue-cured leaf tobacco fields throughout South Korea in 2006. Mosaic caused by potato virus Y and bacterial wilt caused by Ralstonia solanacearum were most severe during harvest season. During last ten years, the damage by tobacco mosaic virus was reduced but the incidence of bacterial wilt increased. These changes of the disease incidences coincide with release time of the tobacco cultivar resistant to the tobacco mosaic virus but susceptible to bacterial wilt pathogen. Wild fire(Pseudomonas syringae pv. tabaci strain ungulate) occurred severely at Kangwon province, though the symptom of wild fire with yellow halo was not observed.

  • Headache is symptom of many people suffered. It caused simply by fatigue, stress, but it also caused by inflammation, mechanical or chemical stimulus, circulation disorder, brain damage. Modern societies develop rapidly by traffic system. But lately it suffering with many traffic problem. Traffic accident is most important of many traffic problem. We experienced a 35 year-old female who complained headache, caused by a traffic accident that happened 22 month ago. We treated the patient by the way of Eo-hyeol (瘀血) type of headache with Herbal medication and Acupuncture. After being treated, the patient show that symptoms(headache, insomnia, anorexia) was improved considerably. This result suggests that oriental medicine treatment has good effect on headache due to traffic accident.

  • An epidemic of the white dusty covering of grape clusters and canes by dust-like particles occurred in many vineyards near Gimcheon, Gyeongbuk area since 2000. Although the covering was severe, it seldom resulted in appreciable damage to vine health except drastical reduction of grape quality. It appears that the abnormal growth of a resident yeast Hanseniaspora (Kloeckera) sp. is related to the white dusty covering on the grape surface.

  • Physilogical disorders of P. ginseng occurred in farmer's field were reviewed in relation to symptom. In root, red skin, rough skin, rust, root rot complex, round root, fine root stripe, freezing injury, cracking, sleeping and uneven emergence were frequently appeared. In leaf and stem, yellowing, early defoliation, leaf bum, Papery leaf, white freezing injury, wind injury, stem cracking were the main troubles. Red skin of root and leaf yellowing gave the greatest negative impact on ginseng production. Some cases of damage by pesticides, excess boron and industrial pollutants were reported. Physiological disorders related to quality factors, such as inside cavity, inside white sponge-like ect. after processing were discussed.
