Outline of Final Research Achievements

Many studies of lipid mediators which are produced from omega 3 fatty acids as precursor have shown the positive effects on periodontal disease and cardiovascular disease related periodontal disease. In this work, linseed oil/κ-carrageenan/chitosan core shell particles could be prepared using linseed oil containing rich α-linolenic acid, namely omega 3 fatty acids and chitosan with nontoxic and biocompatible properties crosslinking by κ-carrageenan. The obtained particles might be use for the oral care materials that have both oxidative stability and antibacterial activity.

Academic Significance and Societal Importance of the Research Achievements

カラギーナンは海藻などに多く含まれる天然多糖であり、カラギーナンの油脂を乳化させる作用と、カラギーナンの硫酸基とキトサンのアミノ基とのイオン結合を形成する作用に着目し、アマニ油とカラギーナン及びキトサンを混合するという単純な方法で複合し、アマニ油/κ-カラギーナン/キトサンコアシェル粒子の調製に至った。アマニ油/κ-カラギーナン/キトサンコアシェル粒子を摂食することで、歯周病進行に伴って口腔で増加するグラム陰性細菌へのキトサンの抗菌効果と、アマニ油中に多く含まれるオメガ3脂肪酸が代謝され、歯周病や循環器疾患に対して生理活性をもつという両方の側面から、歯周病へのアプローチが期待される。
