摘　　要：为探究低聚糖硫酸酯(DEAE)及右旋糖酐硫酸酯(DS-4000)对临床型奶牛乳房炎的治疗效果,将56头患临床型乳房炎奶牛随机分为5组(DEAE组、DS-4000组、DEAE+青霉素组、DS-4000+青霉素组及青霉素对照组),进行药物乳房灌注治疗,每天2次,连用3d,并在治疗前后分别采集奶样进行细菌学检测。临床观察统计各治疗组有效率,细菌检测统计细菌转阴率。结果显示,奶牛乳房灌注DEAE、DS-4000、DEAE+青霉素、DS-4000+青霉素及青霉素进行治疗3d后,总有效率分别为:10.00%、20.00%、58.33%、75.00%和50.00%;乳汁细菌转阴率分别为:0、12.50%、50.00%、54.55%和44.44%。结果表明,DEAE及DS-4000对临床型奶牛乳房炎有一定的治疗作用,但效果不理想,与青霉素联用可以增强抗生素的疗效。In order to detect the clinical efficacy of oligosaccharide sulfate（DEAE）and dextran sulfate （DS-4000）against bovine mastitis,56 cows with bovine mastitis were divided into 5 groups （DEAE group,DS-4000 group,DEAE＋penicillin group,DS-4000＋penicillin group and penicillin group）,and their breasts were perfusion with different drugs twice one day for 3 days. The effective rates of drugs were observed by clinic symptoms.Milk samples were collected before and after treatment of drugs,and the bacterial negative conversion rate of each group were detec-ted by microbial examination.The results showed that total effective rates of 5 groups were 10.00%,20.00%,58.33%,75.00% and 50.00%,respectively,and the bacterial negative conver-sion rates were 0,12.50%,50.00%,54.55% and 44.44%,respectively.In conclusion,the curative efficiencies of the polysaccharides against bovine mastitis were weak,but it could be improved by combination with penicillin.
