Steven-Johnson syndrome (SJS) and toxic epidermal necrolysis(TEN) are severe mucocutaneous reaction which are most frequently caused by drugs. Although the incidence of SJS and TEN is known to be relatively low, outcomes may be fatal. A systematic approach is required because morbidity rate is currently increasing and oral lesion is frequent. We investigated the clinical features and outcomes of 6 patients diagnosed as SJS and TEN and referred from the department of dermatology, Chonnam National University Hospital for oral care. Ketoconazol, Ofloxacin, Chlorphenesin, Amoxicillin, Pontal, Harnal, and Ciprofloxacin were suspected as the causative drugs. Average treatment period was 3.2 weeks, and two patients were referred to 'burn-patients' hospital. Most of oral lesion were cured be normal tissue, but scares with discoloration were observed. For intraoral management, antibiotic disinfection and steroid application were performed according to systemic treatment principles. Additionally, ingestion of zinc, antioxidants, and vitamin was recommended. The establishment of oral treatment principles is demanded because it has not been yet. Also, through investigation of drug side effect and careful prescription are required.

Objectives: To compare and evaluate the degree of abrasion of the denture base resin according to the type of denture cleansers. Methods: Denture base resin specimens were prepared and dried. The resin specimens were installed in the automatic brushing machine so that the toothbrush weighed 200 g. The brushing was performed 1,000 times each, a total of 10,000 times using (1) distilled water (DW), (2) non-abrasive cleanser (NAC), and (3) toothpaste (TP), respectively. Thirty specimens were allocated for each group. The thickness of abrasion by brushing was calculated by converting the weight of the specimen. Results: In all DW, NAC, and TP groups, significant differences were found in the average amount of abrasion of the resin specimen due to 1,000 to 10,000 brushings (p<0.001). The average abrasion amount of the resin specimen due to brushing 10,000 times was 2.31±1.20 ㎛ in DW group, 2.52±0.25 ㎛ in NAC group, 6.50±0.60 ㎛ in TP group, and the amount of abrasion in the TP group was statistically significant compared to other groups (p<0.001). Conclusions: The use of TP is not recommended as a method for maintaining the longevity of dentures and for oral health, and NAC was considered to be possible to be used as a denture cleanser because it had a similar amount of abrasion of that of DW.

With the change of medical environment, people are taking interest not just in treatment but in the prevention of oral diseases. As people's interest in oral diseases increases, the number of dental institutions is increasing continuously and this is heightening the necessity and importance of professional dental hygienists equipped with expert knowledge of oral health. Thus the present study purposed to survey and analyze the current state and weight of works carried out by dental hygienists, and to propose dental hygienists' works desirable in the medical environment changing its focus from treatment to prevention. The results of this study are as follows; 1. In the results of dividing dental hygienists' works into oral examination and preliminary examination, preventive works, assistance to dental treatment, oral health education, hospital administration and management, and surveying the performance rate of these works, the work of the highest performance rate in preliminary examination was collection of patients' systemic history (87.6%). It was also scaling (96.9%) in preventive dental treatment, preparation for treatment (96.5%) in assistance to dental treatment, education on the toothbrushing method (92.3%) in oral health education, and tool disinfection and management (72.2%) in hospital administration and management. 2. When the performance rate was surveyed according to age, institution, and work experience, the performance rate by work area was highest in dental hygienists aged between 27~28, those working at a dental clinic, and those with 4~6 years' work experience. 3. The weight of dental hygienists' works was high in order of assistance to dental treatment (59.1%), observation of oral health condition and preliminary examination (12.4%), oral health education (12.4%), hospital administration and management (10.4%), and preventive dental treatment (5.8%), but in the results of surveying perception on the importance of works, the importance was high in order of oral health education (34.7%), preventive dental treatment (29.0%), observation of oral health condition and preliminary examination (19.3%), assistance to dental treatment (11.2%), and hospital administration and management (5.8%), showing that the weight of works carried out current was different from perception on the weight of works regarded as important. 4. To the question on parts to be developed in response to the change of medical environment, the most frequent answers were the establishment of their roles as preventive dental practitioners (75.7%), and the establishment of their roles as oral health educators (74.9%). This was consistent with the works that dental hygienists gave the highest weight to, and suggested that dental hygienists regarded preventive dental treatment as most important. Development of abilities to give counsel to patients was 55.2%, acquisition of theoretical knowledge of dental treatment 42.1%, improvement in quality as a hospital manager 28.2%, and acquisition of skills to assist dental treatment 23.2%. These show that, even with regard to the development of future oriented dental hygienists' capacities, assistance to dental treatment was perceived less important as it was with regard to the importance of work.

Objectives: To investigate the link between cigarette smoking and muscle strength in Japanese men. Methods: We used data on 4249 Japanese men, aged $43.3{\pm}13.9$ years, in this cross-sectional investigation study. Grip strength and leg strength were measured as indicators of overall muscle strength. Meanwhile, subjects' cigarette smoking habits were recorded by trained medical staff. The effect of cigarette smoking on muscle strength was evaluated. Results: A total of 1618 men (38.1%) were smokers and 1481 men (34.9%) exercised regularly. Significant differences in muscle strength were noted between men with and without a Brinkman index of 400 or greater, after adjusting for age. After adjusting for age, height, body weight and exercise habits, associations between the Brinkman index and leg strength and the ratio of leg strength to body weight were attenuated. Conclusions: Cigarette smoking might be negatively associated with muscle strength, especially grip strength in Japanese men.

Objectives: This study aimed to identify the level of occupational and organizational retention intention and related factors among new dental hygienists. Methods: The participants were 195 dental hygienists employed for less than 24 months. A t-test and one-way analysis of variance were conducted to determine the level of intention to stay according to an individual's major-related characteristics and work environment awareness level. Pearson's correlation analysis was performed for each item, and stepwise multiple regression was performed for factors related to retention intention. Results: In the work environment, the organizational support network had the highest occupational retention intention (β=0.513). Organizational retention intention (β=0.351), working infrastructure (β=0.293), cooperation relationship (β=0.165), and management justice (β=0.151) were factors related to organizational retention intention (p<0.001). Employment at the practice hospital was related to occupational (β=0.167) and organizational retention intention (β=0.138), and satisfaction with clinical practice was related to occupational retention intention (β=0.327). Conclusions: New dental hygienists are expected to be actively utilized for long-term tenure in both occupations and organizations by actively reflecting on the results obtained through this study in the curriculum and working environment of dental hygienists.

Former studies dealing with combined effects caused by chemical compounds in the metabolically competent hepatoma cell line Hep G2 indicated that Hep G2 cells are useful and sensitive indicators for the identification of synergisms of promutagens, comutagens and antimutagens which are relevant in eukryontic (human) cells. In the present study we examined the modulation of DNA damages by the suspected antimutagens ascorbic acid, beta-carotene, alpha-naphthoflavone and beta-naphthoflavone in Hep G2 cells.(omitted)
