摘要
The vaginal endoscopy was performed in two Labrador Retrievers from onset of vaginal bleeding until metestrus accompanying with vaginal smear and blood progesterone concentration to investigate estral changes, and the intrauterine infusion of radiopaque fluid using vaginal endoscope (rigid 25-degree endoscope, Karl Storz) was detected by radiogrphy to determine if theis technique is feasible for future artificial insemination in the dogs. During the proestrus vaginal mucous membrane folds were edematous and a large amount of clear red discharge was present. In the beginning of estrus, the mucous membrane folds was present and the amount of the red discharge was decreased. In the estrus there were obbvious shrinkage, angulation of the membrane folds and decreasing of the discharge. In metestrus the vaginal folds started to round out and the surface appeared moist and sticky. The endoscope used for endoscopic monitoring of the vaginal mucosa was advanced until the external os of the cervix could be visualized. A plastic catheter, 8Fr guage was manupulated into the cervical os and then advanced through into the uterus. The radiopaque fluid was injected into the uterus through the catheter and radiographs taken to detect the site of insemination using the endoscopic technique revealed the exact infusion of the fluid in the uterus, consequentlyto prove that this technique is usable for more successful artificial insemintion tn the bitch.

阴道内镜检查是从阴道出血开始到发生睾丸炎并伴有阴道涂片和血液中的孕酮浓度的两种拉布拉多犬进行的，以研究雌激素的变化，并使用阴道内窥镜（刚性25度内窥镜，Karl Storz）在子宫内输注不透射线的液体。通过放射线照相术检测以确定该技术是否可用于将来的狗的人工授精。在发情期间，阴道粘膜褶皱水肿，并且存在大量的透明红色分泌物。在发情期开始时，存在粘膜褶皱，红色排出量减少。在发情期有明显的收缩，膜褶皱成角和分泌物减少。在肠系膜中，阴道皱褶开始变圆，表面看起来湿润且发粘。用于内窥镜检查阴道粘膜的内窥镜已经发展到可以看到子宫颈的外部口。将一个塑料导管8Fr规线插入宫颈口，然后推进子宫。通过导管将不透射线的液体注入子宫，并使用内窥镜技术拍摄的放射线照片检查了授精的位置，揭示了子宫内液体的准确输注，因此证明该技术可用于母狗更成功的人工授精。
