Study on health

我们调查了口腔健康状况与健康促进因素之间的相关性。我们认为，口腔区域的健康促进因子将发挥重要作用，以防止一个人感染严重的疾病，通过呼吸和喂养。我们按照WHO口腔检查程序，对80岁时保留自己牙齿20颗的老年人（我们称之为8020人）进行了口腔检查。检测口腔细菌植物群组成、唾液成分、唾液容量、唾液缓冲能力。通过对血液成分、饮食习惯、运动能力等指标的研究，探讨其与口腔健康状况的关系。研究的细菌种为白色念珠菌、变形链球菌。远缘链球菌、肺炎链球菌、铜绿假单胞菌、金黄色葡萄球菌。此外，我们还对唾液中的抗菌肽，如防御素和组胺素进行了定量分析。

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.
