B-型超声波诊断猕猴早期妊娠

Diagnosis of Early Pregnancy in Rhesus Monkey by Ultrasonography

采用便携式Ｂ型超声波检查了３８例早孕猕猴，其中孕期在１８～３０ｄ的猴２３例，确诊２２例，可疑１例；孕期在３１ｄ～６０ｄ的猴１５例均得以确诊。Ｂ超显示妊娠早期猕猴宫内有一均匀的强回声区，妊娠囊多数为圆形或椭圆形，数目单一，大小与孕期相符。随着孕期延长，可见胎芽、胎心搏动等现象。正常猴子宫的长度在２８ｍｍ以下，宽度在２２ｍｍ以下，未见强回声区。

UltrasonicB was used for the diagnosis of early pregnancy in Rhesus monkey,23 cases at 1830 days of gestation were confirmed in 22 with one suspected,15 cases at 3160 days of gestation were all confirmed by the diagnosis.In early pregnancy monkeys,a region of even and strong echogram and single gestational sac(GS) may be seen in their uteri.Most of the GS were round or oval in shape and the size increased with the length of the gestational period.With the advance of the gestation,fetus and heartthrob of the embryo may be seen.The size of the uterus in normal monkey during breeding season was less than 28mm in length and 22mm in width,no strong echogram region was found in the uterus.
