본 연구는 면역화된 산란계로부터 생산된 계란 난황중에 들어있는 S. mutans균주의 specific IgY를 분리하여 면역화 여부, Specific IgY 농도별 및 균수별에 따른 항균력을 현미경적 및 탁도측정에 의한 IgY의 항균력 효과를 검토하고자 실시하였다. 면역화 여부에 따른 탁도시험 결과 면역처리된 처리구에 crude IgY를 10%와 20% 첨가에 의해 항균 효과가 있었다. 면역을 하지 않은 닭에서 생산된 계란으로부터 추출한 IgY를 10% 첨가구와 대조구에서는 응집반응을 나타내지 않았다. 그러나 S. mutans로 면역화된 닭에서 생산된 계란에서 추출한 IgY의 10%첨가구는 상등액과 침전물에서는 균들이 응집되는 현상을 보였다. 면역화된 조난황 specific IgY를 첨가한 처리구가 대조구 보다 S. mutans균들이 응집되는 정도에 있어서 확실한 효과를 나타내었다. 조 난황 specific IgY의 농도별 시험에서는 5%이상 첨가구 들에서는 전반적으로 균체들의 응집현상이 나타났으며 IgY를 2.5% 이하로 첨가한 처리구와는 확연한 차이를 보였다. 탁도에 있어서도 조 난황 specific IgY 농도별 시험에서는 첨가농도에 따라 차이가 있었지만 10% 이상 첨가구에서는 탁월한 효과를 나타내었다. 응집된 균괴의 크기는 IgY첨가량이 증가할수록 점점 더 커져가는 현상을 나타내었다. 균수별에서는 $10^5\;cfu/mL$ 이상 접종구에서는 균체들이 응집되는 현상을 보였으며 균수가 많을수록 더욱 응집되는 현상을 나타내었다. Plaque 형성력은 감소하는 경향을 보였으며 IgY 농도 15%에서는 plaque 형성이 약 75%가 저해되었다. 따라서 면역화된 닭으로 부터 생산된 계란에서 추출된 crude IgY를 사용하여 S. mutans균으로부터 발생된 충치를 예방할 수 있을 것으로 사료되었다.

Purpose : This study aimed to analyze the antibacterial activity of Liriope platyphylla ethanol extract (LPEE) against Streptococcus mutans and Porphyromonas gingivalis and to validate its potential for the prevention and treatment of dental caries, gingivitis, and periodontal disease. Methods : To verify the antibacterial effect of L. pulsatilla ethanolic extract (LPEE) against S. mutans and P. gingivalis, the disk diffusion method was used to determine the inhibition zones at concentrations of 50, 100, 200, and 300 mg/㎖. To determine the minimum inhibition concentration (MIC), the final dose of LPEE was .2, .4, .8, 1.6, 2.5, and 5.0 mg/㎖, and the minimum bactericidal concentration (MBC) was determined based on the MIC results. To confirm the growth inhibitory effect of LPEE on both pathogens, the absorbance was measured at 600 nm after each incubation for 0, 3, 6, 12, and 24 hr at concentrations of .8, 1.6, 2.5, and 5.0 mg/㎖. Results : The cytotoxicity of LPEE was evaluated and the cell viability was more than 70 % at 400 mg/㎖. Therefore, concentrations of 50, 100, 200, and 300 mg/㎖ were used in this study. The antimicrobial effect against S. mutans was seen at 100 mg/㎖ and grew in a concentration-dependent manner, while P. gingivalis was effective at 50 mg/㎖ with the dose dependency. The MIC was .8 mg/㎖ for both strains, and the MBC was 1.6 mg/㎖ with the same results. The growth inhibitory effect of LPEE on S. mutans and P. gingivalis was observed, even at low concentrations. Conclusion : The antibacterial effect of LPEE was evaluated through the analysis of MIC, MBC, and growth inhibition effect on S. mutans and P. gingivalis, which suggests LPEE might have the possibility of utilization as a preventive and therapeutic composition for oral diseases.

How can the educator help learners to learn? The old way was to tell learners as much as possible, passing on the educator's knowledge. Now the educator acts as a helper. She will organise experiences which allow the learners to do health behaviors, she may utilize instructional materials, she may write downsome questions for a group of learners to discuss. In all these ways the teachers is helping learning. Some educators feel that they must do all the talking themselves. They feel that they are not really teaching the learners some new information, but this is quite wrong. In fact if a educatorgives a lecture and learners do not learn, then the educator is talking not teaching. So the devlopment of instructional materials is much needed to be a learner education. And the selection of materials may be very important for the level of maturity of the learners in interest, complexity of ideas, opportunity for self-identification, speed of learners' ability to observe and length of concentration. Author studied the several instructional materials which can be utilized in the field of dental health education and also studied their values, limitations and considerations when they are used. The learning activities are poster, puppet, model, mock-up, specimen, flannel board, chalk board, bulletin board, psychodrama, role play, field trip, exhibition, laboratory method.
