Results By celioscopic diagnosis, 109 females (54.5%) found ill with chronic pelvic inflammatory disease, 55(27.5%) with endometriosis 18 with phase Ⅰ~Ⅱ, 37 with phase Ⅲ~Ⅳ, 12(6% with polycystic ovarian syndrome, 8(4%) with pelvic tuberculosis and 4(2%) with malformation of internal genitalia. The other 12 ones (6%) had normal pelves.

结果 200例中经腹腔镜诊断为慢性盆腔炎并输卵管病变109例(54.5%)；子宫内膜异位症55例(27.5%)，其中Ⅰ~Ⅱ期的18例，Ⅲ~Ⅳ期的37例；多囊卵巢综合征12例(6%)；盆腔结核8例(4%)；内生殖器畸形4例(2%)；正常盆腔12例(6%)。60例经腹腔镜治疗后妊娠(30%)。

The trophoblast blood flow spectrum could be easily detected with the guide of CDE.The ultrasonic findings were characterized by broad arterial flow spectrum,high diastolic component of the low resistance trophoblastic flow,RI＝0.40～0.51 with single or biphasic spectrum.The salpingian ring with high blood flow indicated early and complete salpingian pregnancy.

结果：①异位妊娠包块血流信号丰富，血管连续性好，能较完整显示血管床、血管网及范围广的低流速血流信号；②脉冲多普勒取样为滋养层周围性血流频谱，其特征为：频谱增宽、单相或双相持续存在、阻力降低(RI＝0.44±0.04)、舒张期血流丰富的动脉频谱；③具有鲜明丰富的滋养层周围性彩色血流频谱特征的&输卵管环&是早期输卵管妊娠的特征性表现，并提示是输卵管完整存在的标志。

Diestrus: Lasting 60 to 90 days, diestrus is the period when the reproductive tract is under the control of the hormone progesterone.

发情间期：这段时期持续约 2-3 个月。发情间期，母犬生殖系统处于妊娠激素的调控之下。

It was shown that: 1 MMP2 activity reached the highest level during proestrus, and was lowest during diestrus; 2 MM2 acti vity was increased from the first day of pregnancy, peaked on day 4 of pregnancy; but decreased significantly at day 7 of the pregnancy. 3 MMP2 activity was obviously higher on day 1 of pseudopregnancy than on the other days, and its activity decreased gradually, reached the very low level at day 4 of pseudopregnancy and maintained the low level until day 7; 4 MMP2 activity was decreased significantly 24 hours after injection of 17βestradiol ( 01 mg) at metaestrus, while MMP2 activity had no change after progesterone (04 mg) injection.

明胶酶A活性变化如下：1在大鼠的动情前期明胶酶A的活性最高，间情期最低；2在妊娠早期(1～7天)的卵巢中，明胶酶A的活性在妊娠第4天达到最高，第1～3天及第5、6天其活性也较高，但第7天则明显下降；3在假孕(1～7天)大鼠的卵巢中，明胶酶A的活性在假孕第1天最高，第2、3天略下降，从第4天到第7天，其活性都处于较低水平；4动情后期大鼠皮下注射雌二醇(0.1mg/只)24小时后，明胶酶A活性明显上升。
