This experiments 's aim consist in observe absorb medical membrane be used for prevent operation behind adhesion 's effect. It means adopt watchdog do knee joint prevent adhesion performance test; Adopts Japan big white rabbit difference do intestines adhesion, Tendon damages prevent adhesion experiment. Experiments group use absorb medical membrane prevent adhesion, Masculine contrasts group use other prevent adhesion material prevent adhesion 's take place. Blank group does not do disposal. Kills prove absorb medical membrane prevent adhesion effect obviously. 1, Knee joint prevents adhesion performance 　　 Will absorb medical membrane implant watchdog knee joint, Establishes oneself contrast model, Passes generally observation, Histology observe and knee joint act situation come evaluate glue gram TM membranous organization consist with sex and prevent adhesion effect. Pass experiment indicate: Membrane organization consists with sex good, 4 week time although already obviously degeneration, But basic keeps membranous shape, Experience slanting nothing but singularity inflammation reaction, Shares middle muscle with surrounding organize exist natural clearance, And, Experiences lean knee joint straighten measured obvious than contrast side slightness. Absorbs medical membrane possess good prevent adhesion performance. 2, Intestines adhesions experiment 　　 1.5% Wu barbitone marries ( 30mg/ kg) Rabbit ear fate intravenous anesthesia, Has not germ dirty abdomen midmost cut 6cm long, Brings up caecum and part ascending colon, Uses physics means result in colon chorion to intestines a dot Chuang bleeding, 3% tincture of iodine burns intestines has been one minute. Experiments group use absorb medical membrane cover injured area; Contrasts group use other prevent adhesion material cover injured area; Blank group uses physiological saline spread the cloth injured area. Comes back marry intestines a section close abdomen. 　　 Test result: Have operated behind and 12 week each group animal average survive for 7 week. Experiences behind naked eye do not see granulation tissue environment group operation, Naked eye does not see membrane, Intestinal canal lubricity, Between intestinal canal, Intestinal canal with not see adhesion and cicatrice peritoneum between does. Experiences group, Masculine contrasts group with blank contrast group comparation: P< 0.01; Experiences group with masculine contrast group comparation: P< 0.05. Absorbs medical membrane adversaryart hind gut adhesion 's affection Blank has contrasted group photo for 4 week: Part appears membranous 's adhesion: Has experienced group photo for 4 week, Has not adhesion under cut, Has not adhesion between intestinal canal. 3, Tendon adhesions experiment 1.5% Wu barbitone marries ( 30mg/ kg) Rabbit ear fate intravenous anesthesia, Has not germ dirty rabbit cut upper part thigh, Separates subcutaneous tissue and shallow a layer tendon membrane, Debunks come out thigh muscle and tendon, Dissociate come out muscle and tendon, Cuts break stitch sew up break hold behind tendon. Experiences group membrane cover in tendon suture; Masculine contrasts group use other prevent adhesion material cover tendon suture; Blank group does not do any disposal. Test result: Experiences group tendon, Muscle gradation clear, Not see adhesion and cicatrice organization tendon surrounding does. Experiences group, Masculine contrasts group with blank contrast group comparation: P< 0.01; Experiences group with masculine contrast group comparation: P< 0.05.
