When cartilagenous surfaces interacted with silicone rubber that index was 3 to 6 times higher. Putting of 3-6 mg/cm<sup>2 </sup>of egg or synthetic polymerized phosphatidylcholone on the surface of silicone rubber considerably decreased the friction coefficient at interaction of rubber with the cartilagenous surface while the administration of the same quantity of egg phosphatidylcholine in the form of 10% aqueous suspension into the friction zone gave no effect. The data obtained indicate that the of phospholipids for the improvement of tribological characteristics of joint implants is a prospective one.</italic></p></abstract><trans-abstract xml:lang="ru"><p><italic>В модельных опытах установлено, что коэффициент трения при взаимодействии нативных суставных хрящей находился в пределах 0,02—0,07 (в зависимости от величины нагрузки). В паре трения хрящ-силиконовая резина этот показатель был в 3—6 раз выше. Нанесение на поверхность силиконовой резины яичного или синтетического полимеризуемого фосфатидилхолина в количестве 3—6 мг/см<sup>2</sup> существенно снижало коэффициент трения при взаимодействии резины с хрящом, тогда как введение в зону трения такого же количества яичного фосфатидилхолина в виде 10% водной суспензии было неэффективным. Полученные данные свидетельствуют о перспективности применения фосфолипидов для улучшения трибологических свойств эндопротезов.</italic></p></trans-abstract><kwd-group xml:lang="en"><kwd>phospholipids</kwd><kwd>articular cartilage</kwd><kwd>silicone rubber</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>фосфолипиды</kwd><kwd>суставной хрящ</kwd><kwd>силиконовая резина</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Белоенко Е.Д., Гончарова Н.В., Родненков В.Г. и др. //Ортопед. травматол. — 1989. — N 8. —С. 24-27.</mixed-citation></ref><ref id="B2"><label>2.</label><mixed-citation>Василенко И.А., Краснопольский Ю.М., Степанов А.Е. и др. //Хим.- фарм. журн. — 1998. — N 5. — С. 9-15.</mixed-citation></ref><ref id="B3"><label>3.</label><mixed-citation>Воронович И.Р., Купчинов Б.И., Родненков В.Г. и др. //Ортопед. травматол. — 1987. — N 4. — С. 71-73.</mixed-citation></ref><ref id="B4"><label>4.</label><mixed-citation>Ермаков С.Ф. //Трение и износ. — 1988. — Т. 9. — С. 322-327.</mixed-citation></ref><ref id="B5"><label>5.</label><mixed-citation>Ермаков С.Ф., Белоенко Е.Д. //Конф.
