Objectives: This study analyzed the relationship between dietary behavior and health-related characteristics and experiences of major oral disease symptoms using online raw data on adolescent health behavior. Methods: Using the raw data on 61,858 adolescents collected through the 13th Adolescent Health Behavior Online Survey, a complex samples logistic regression analysis was conducted to assess risks of major oral diseases. Results: The less one consumes sweet drinks and the more one eats vegetables per day, the less likely one is to experience symptoms of tooth decay and periodontal diseases. Undergoing scaling and oral health education help prevent major oral diseases. Brushing after school lunch prevents periodontal diseases and foul breath, and using dental floss and interdental brush also help prevent periodontal diseases. Conclusions: To minimize experiences of oral diseases during adolescent years, it is necessary to periodically scale teeth and provide knowledge regarding the personal management of dental plaque through school oral health education.

Purpose: Obstructive and inflammatory disease often occurs in the major salivary glands, and no predictive treatment has yet been developed for this condition. The aim of this report was to introduce an intraductal irrigation procedure and to illustrate its application to practical patient cases. Materials and Methods: Two patients complaining of pain and swelling in the parotid gland during meals who underwent sialography were diagnosed as having sialodochitis with sialadenitis. Intraductal irrigation was then performed on the parotid gland on the side of the complaint. The irrigation procedure was conducted in the same manner as the sialography procedure, except that saline was used as the filling solution. Symptom severity was evaluated with a numerical rating scale (NRS) at the initial visit and a month after the irrigation. Results: The initial NRS value of patient 1 was 10. The value decreased to 6 and then to 0 after 2 irrigation procedures. The NRS value of patient 2 regarding the symptoms involving the left parotid gland decreased from 4-5 to 1 after 4 irrigation procedures performed at 1-month intervals. Conclusion: Intraductal irrigation of the salivary gland may be a simple, safe, and effective treatment option for patients with obstructive and inflammatory disease of the salivary gland that is capable of resolving their symptoms.

Erythema multiforme (EM) is an inflammatory immune-mediated mucosal disease. EM is classified as EM minor or EM major, depending on the severity of symptoms. Most patients with minor or major forms of EM have oral lesions. EM can occur as a result of adverse drug reactions but this is difficult to establish. Several indicators have been developed that can be used as a criterion of evaluation to ensure objectivity in identifying the causality of adverse drug reactions. The Naranjo algorithm was used in the evaluation to ensure objectivity in identifying the causality of adverse drug reactions. There were two cases of patients suspected of having EM induced by drugs. They were both assessed using the Naranjo algorithm to confirm the causality of the disease.

In oriental medicine, the fruit of Actinidia polygama has long been used to alleviate the symptoms of gout, arthritis, and inflammation. In this study, it was to designed to analyze the antibacterial activity of A. polygama ethanol extract (APEE) against Streptococcus mutans, one of the major strains for dental caries, and Porphyromonas gingivalis, one of the critical strains for periodontal disease. The antibacterial activity of APEE was analyzed by disk diffusion, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) assays. In addition, it was also analyzed the inhibitory effect of APEE on bacterial growth and biofilm formation against both oral pathogens. APEE exhibited its antibacterial effect through the inhibited bacterial diffusion as well as low concentration of MIC and MBC. In addition, APEE significantly inhibited not only bacterial growth but also biofilm formation in a dose-dependent manner. Consequently, APEE showed potent antibacterial activity against both S. mutans and P. gingivalis, which indicates that APEE might be used as a potential antibacterial material for the improvement of oral healthcare.

Pepper anthracnose is one of the major limiting factors in pepper production. Boring last over 10 years, Colletotrichum gloeosporioides has been known as the most prevalent species among five Colletotrichum spp. involved as anthracnose causing agents. Recently, however, the change of major species with pepper anthracnose has been proposed. Identification study was peformed on 12 test isolates collected from anthracnose disease symptoms on pepper during 2001-2002 and 25 reference isolates obtained from several other host plants. The identification of the isolates with morphological observation and IfS region sequence comparison resulted that 11 ones from 12 test isolates colleted from pepper anthracnose during 2001-2002 were identified as C. acutatum. PCR using species-specific primers designed from ITS region sequence suggested a rapid diagnosis method in identifying C. acutatum from C. gloeosporioides.

Systemic lupus erythematosus (SLE) is an episodic, multi-system, autoimmune disease characterized by widespread inflammation of blood vessels and connective tissues and by the presence of antinuclear antibodies (ANAs), especially antibodies to native (double-stranded) DNA (dsDNA). Its clinical manifestations are extremely variable, and its natural history is unpredictable. Untreated, SLE is often progressive and has a significant fatality rate. The most widely used criteria for the classification of SLE are those of the American College of Rheumatology (ACR), which were revised in 1982 and modified in 1997. The presence of four criteria have been diagnosed as a SLE. Rashes are common at onset and during active disease. The oral mucosa is the site of ulceration with SLE. Arthralgia and arthritis affect most children and these symptoms are short in duration and can be migratory. Lupus nephritis may be more frequent and of greater severity in children than in adults. The initial manifestation of nephritis is microscopic hematuria, followed by proteinuria. The most common neuropsychiatric symptoms are depression, psychosis(hallucination and paranoia) and headache. CNS disease is a major cause of morbidity and mortality. Pericarditis is the most common cardiac manifestation. Libman-Sacks endocarditis is less common in children. The most frequently described pleuropulmonary manifestations are pleural effusions, pleuritis, pneunonitis and pulmonary hemorrhage. During the active phase ESR, CRP, gamma globulin, ferritin and anti-dsDNA are elevated. Antibodies to dsDNA occur in children with active nephritis. Antibodies to the extractable nuclear antigens (Sm, Ro/SS-A, La/SS-B) are strongly associated with SLE. Specific treatment should be individualized and based on the severity of the disease. Sepsis has replaced renal failure as the most common cause of death.

A leaf blight disease was found on Fatsia japonica plants growing in the first author's apartment garden in May, 2003. Major symptoms were leaf blight and petiole rot. A species of Phytophthora was isolated from the lesions. The isolate readily produced sporangia and sex organs on V8 juice agar plates. Sporangia were papillate, ovoid to subspherical and caducous with a pedicel. Sporangia were 33.6-38.4 ${\times}$ 33.6$\mu\textrm{m}$ with 1/b ratio approximately 1.14, papillae 4-5$\mu\textrm{m}$ high, pedicels also 4-5$\mu\textrm{m}$ long. Oogonia were spherical, 28.8$\mu\textrm{m}$ in diameter. Antheridia were globose, 14.4$\mu\textrm{m}$ in diameter and mating with oogonia paragynously. Mycelia grew best at 30$^{\circ}C$ and did not grow at 35$^{\circ}C$ or above, and at 5$^{\circ}C$. The morphological characteristics conformed to P. cactorum (Leb. And Cohn) Schroeter.

Tempormandibular Joint pain and dysfunction is a common and important clinical problem. With the recent advances in imaging technology, radiologists have made major contribution to the understanding of TMJ disease. The MRI has several advantages over the conventional imaging methods. It is possible to obtain surprisingly precise images of internal hard and soft tissues with MRI. It is not invasive without ionizing radiation. The abnormal disk position has been thought as the cause of TMJ internal derangement. But there are few methods to relate disk position to TMJ internal derangement quantatively. The object of our study is to determine the amount of anterior displacement fo articular disk in symptomatic patients related each symptoms. Using the method of Dr. Drace, we studied the 38 joints of 22 persons with susceptable TMJ internal derangement. 1. In determining the anterior displacement of TMJ articular disk, the junction between the posterior band and bilaminar zone was useful. 2. The mean anterior displacement of disk in reduction group and without reduction group were $51.0^{\circ}C$ and $81.1^{\circ}C$ respectively. The difference was significant. 3. In the mean anterior displacement of disk, the pain without clicking group showed $84.8^{\circ}C$ and the clicking and pain group $70.8^{\circ}C$, the clicking group respectively.

This study aims to analyze the oral health status of the elderly. Study subjects were 9,340 elderly aged over 65 who took the health examination (the first) for the local insured when the National Health Insurance Corporation carried out its survey from January to December, 2002. The subjects took an oral examination and filled in the questionnaire. Major results from the analysis are as follows: 1. Analysis of Oral Health Behavior For oral health behavior, 38.2％ of total subjects had visited a dental hospital (or clinic) in the last one year in the order of the elderly of big cities (48.3％), the elderly of medium cities (43.9％), and the elderly of rural areas (29.0％)(P<0.001). Elderly men had a higher rate than elderly women, and the younger age had a higher rate(P<0.01). For experience of oral prophylaxis, 12.3％ of the total elderly had experienced it in the order of the elderly of big cities (18.8％), the elderly of medium cities (16.0％), and the elderly of rural areas (6.4％) (P<0.001). For elderly men, the younger age had a higher rate of oral prophylaxis. The number of toothbrushing in order was twice(47.5％), once (26.7％), three times (25.0％), and none (0.7％). The younger age brushed their teeth more often (P<0.001). 2. Analysis of Oral Health Status The rate of caries was 10.6％ of the elderly surveyed. By area, the elderly of rural areas had a higher rate of caries than the elderly of cities (p<0.001) and elderly men were higher than elderly women (p<0.001). By age, many elderly aged over 80 had more than two caries. For missing teeth, the elderly of rural areas had a higher rate than the elderly of cities (p<0.001) and the older age had a higher rate(p<0.001). The rate of periodontal disease was 43.2％ of the total elderly. By area, the elderly of big cities (46.2％) had a higher rate of periodontal disease than the elderly of medium cities (39.4％) and rural areas (43.6％)(p<0.001), and elderly men (46.4％) were higher than elderly women (40.2％)(p<0.001). By age, the lower age had a higher rate of peridontal disease (p<0.001). Dental abrasion was observed in 16.9％ of the total elderly. The elderly of cities (21.0％) had a higher rate than the elderly of rural areas (12.0％)(p<0.001) and elderly men (21.3％) were higher than elderly women (12.8％)(p<0.001). Also the lower age had more dental abrasion symptoms (p<0.001). For needing a denture, the rate among the elderly was 48.5％ and was higher for the elderly of rural areas(20.9％), than the elderly of big cities(7.0％) and medium cities (10.5％)(p<0.001). For the rate of denture wearing, the elderly of rural areas(41.8％) were higher than the elderly of big cities (27.7％) and medium cities (28.2％ )(p<0.001). For the relation of drinking and smoking to oral health, the elderly who had a higher frequency of drinking, had a higher rate of caries (p<0.001)periodontal disease(p<0.001) and missing teeth(p<0.001) Smokers had a higher rate of caries (p<0.001), periodontal disease (p<0.05), and missing teeth (p<0.001) than nonsmokers.
