OBJECTIVE
The aim of this study was to evaluate changes in the endometrium by using echotexture parameters during and after treatment of endometritis with intrauterine administration of an intrauterine antiseptic solution (Lotagen®, 3% metacresolsulphonic acid and formaldehyde) in cows which became pregnant after treatment.
MATERIAL AND METHODS
According to the severity of endometritis 21 cows were divided into three groups: E1 (slight, n = 7), E2 (moderate, n = 8), E3 (severe, n = 6). The control group (C, n = 11) consisted of cows without endometritis that did not receive an intrauterine medication. A software (Bs200 Pro®) was used to evaluate echotexture parameters Contrast (CON), Gradient (GR), Homogeneity (HOM), Mean Gray Level (MGL) of images taken during the examinations at hours (h) 0, 1 and 6 and days (d) 2, 3, 5 and 10.
RESULTS
At 0 h, GR was significantly lower in group E2 than in groups E1 and C (p < 0.05). There was an increase in GR values between 0 h and 10 d in group E2 and E3, but a decrease during the same time interval in group C (p < 0.05). In contrast, CON values of group E2 were lower (p < 0.05) at 0 h compared to other timepoints of examination and lower than in group C. HOM values were lower (p < 0.05) in groups E1, E2 and E3 than in group C on d 5 and d 10. HOM values were higher at 1 h compared to 6 h, d 2 and d 10 in group E3 (p < 0.05). By contrast to GR values, HOM values were higher in group C at 6 h and d 10 than they were in group E3. MGL values of group E2 were higher (p < 0.05) than in group C until d 10 and higher (p < 0.05) in group E3 than in group C at 6 h after treatment. In group E2 an increase of MGL values until d 2 was followed by a decrease (p < 0.05).
CONCLUSION
Echotexture parameters determined by the evaluation of sonographic B-mode images reflect changes in the endometrium and could be used for the evaluation of the recovery period after treatment of endometritis.
目的
本研究旨在通过超声纹理参数评估在对患子宫内膜炎的奶牛子宫内施用子宫内抗菌溶液（Lotagen®，3%间甲酚磺酸和甲醛）治疗期间及之后，且治疗后怀孕的奶牛子宫内膜的变化。
材料与方法
根据子宫内膜炎的严重程度，将21头奶牛分为三组：E1组（轻度，n = 7）、E2组（中度，n = 8）、E3组（重度，n = 6）。对照组（C组，n = 11）由未患子宫内膜炎且未接受子宫内用药的奶牛组成。使用一款软件（Bs200 Pro®）评估在0小时、1小时和6小时以及第2天、3天、5天和10天检查期间所拍摄图像的超声纹理参数对比度（CON）、梯度（GR）、均匀性（HOM）、平均灰度值（MGL）。
结果
在0小时时，E2组的GR显著低于E1组和C组（p < 0.05）。E2组和E3组在0小时至10天期间GR值升高，但C组在同一时间间隔内GR值降低（p < 0.05）。相比之下，E2组在0小时时的CON值低于其他检查时间点且低于C组。在第5天和第10天，E1组、E2组和E3组的HOM值低于C组（p < 0.05）。在E3组中，1小时时的HOM值高于6小时、第2天和第10天（p < 0.05）。与GR值相反，C组在6小时和第10天的HOM值高于E3组。在第10天之前，E2组的MGL值高于C组（p < 0.05），治疗后6小时E3组的MGL值高于C组（p < 0.05）。在E2组中，MGL值在第2天之前升高，之后降低（p < 0.05）。
结论
通过超声B模式图像评估确定的超声纹理参数反映了子宫内膜的变化，可用于评估子宫内膜炎治疗后的恢复期。
