Study on health

我们调查了口腔区域健康状况与健康促进因素的相关性。我们假设口腔区域的健康促进因子在防止男性通过呼吸和进食感染严重疾病方面发挥了重要作用。我们根据who口腔检查程序，对80岁时保留20颗牙齿的老年人（我们称之为8020人）进行口腔检查。详细检查口腔细菌菌群组成、唾液成分、唾液量、唾液缓冲作用。研究血液成分、饮食习惯、运动能力与口腔健康状况的关系。研究的细菌种类有白色念珠菌、变形链球菌。链球菌，肺炎链球菌，铜绿假单胞菌，金黄色葡萄球菌。血友病、流感等。此外，我们还关注了唾液中的抗菌肽，如防御素和组蛋白，并对这些肽进行了定量分析。

We investigated correlation between health status and health-promoting factors in the oral region. We assumed that health-promoting factors in the oral region would play an important role to prevent a man from infecting serious diseases through respiration and feeding. We performed oral examination of elderly people who keep their own teeth of 20 at the age of 80 (we call them 8020 people), according to WHO oral examination procedures. In detail, composition of oral bacterial flora, saliva constituent, saliva volume, salivary buffering were examined. Blood constituent, diet convention, athletic capacity were studied to clarify their relation with oral health status. Bacterial species studied were Candida albicans, Streptococcus mutans. Streptococcus sobrinus, Streptococcus pneumoniae, Psedomonos aeruginosa, Staphylococcus aureus. Haemophilias oarainfluenzae, etc. Furthermore, we put our attention on antibacterial peptide in saliva, such as defensin and histatin, and did quantitative analysis of these peptides.
