摘　　要：为阐明氯前列烯醇治疗奶牛持久黄体的作用机理,通过直肠检查结合超声仪探查确诊16头患持久黄体的奶牛,分为治疗组(n=10)和空白对照组(n=6),治疗组采用氯前列烯醇给予治疗,空白对照组则不给予药物处理。结果发现采用氯前列烯醇治疗后,治疗组总有效率为90%,而空白对照组自愈率为16.7%,二者差异极显著(P<0.01)。结果表明,氯前列烯醇确实对黄体有特异性溶解作用,对子宫机能恢复起到理想的作用。试验期间,应用超声仪对患畜黄体及卵泡的变化进行监测,从超声影像诊断结果来看,治疗组奶牛黄体在停药后1~2 d直径下降明显,其卵泡直径在停药后1~2 d呈现明显上升趋势,而空白对照组平均黄体直径在整个监测周期内总体趋势基本保持不变。The aim of the present study was to expose the underling mechanisms of the therapeutic effect of cloprostenol on persistent corpus luteum in dairy cows. A total of 16 dairy cows with persistent corpus luteum confirmly diagnosed by rectal examination and uhrasonography examination were randomly assigned to one of two groups such that experimental group （n=10） received cloprostenol treatment and blank control group （n=6） received no treatment. The results revealed that there were significant differences between the total effective rate of the cloprostenol treatment group （90%） and the spontaneous cure rate of blank control group （16.7% ,P〈0.01 ）, indicating that cloprostenol had a specific luteolytic effect and was helpful for the functional recovery of uterus. The morphological changes of corpus luteum and follicle were monitored by ultrasonography examination. The results of the ultrasonography examination demonstrated that during the two days after drug withdrawal, the diameters of the corpus luteum and follicle of the dairy cows in cloprostenol treatment group was obviously decreased and increased, respectively; no obvious changes of corpus luteum diameters of the dairy cows in blank control group were observed during the whole monitoring period.
