    The Sounds Of fetal heart and umbilical vessels (fast sound), the sound of uterine ar teries (slew sound) and the sound of fetal movements were used as indications of pregnancy. 64 goats were tested at different stages following mating (302 cases in total) by Doppler ultrasonic technique. When any of the above four sound signals was recognized, positive diagnosis was made. The results showed that 58 animals (274 cases) were pregnant and all the goats pregnant more than 50 days had been detected; pregnancy was...

    The Sounds Of fetal heart and umbilical vessels (fast sound), the sound of uterine ar teries (slew sound) and the sound of fetal movements were used as indications of pregnancy. 64 goats were tested at different stages following mating (302 cases in total) by Doppler ultrasonic technique. When any of the above four sound signals was recognized, positive diagnosis was made. The results showed that 58 animals (274 cases) were pregnant and all the goats pregnant more than 50 days had been detected; pregnancy was confirmed later by lambing. Six (28 cases) were nonpregnant and no pregnant signal wes found except one estrous case in which slow sound was received.

    The hearts of normal fetus between 18 and 40 weeks of gestation were examined by cross-section and M-mode echocardiography. The common used cross-section was four chamber long axis, left ventricular long axis, short axis of aortic and pulmonary valve, and the specific plane of fetal. First, the image of the fetal heart of the examining site should be observed by crosssection echocardiography, then the M-line must be positioned by accurate cross-sectional guidance and the image was froze, measured, and recorded....

    Morphological features of the developing human fetal cardiac muscle cells in culture was observed with scanning electron microscope. Myocardial tissue masses were isolated from three human fetus of 10, 13 and 16 week's gestation. They were cultured in vitro. New cardiac muscle cells grew and detached from the tissue masses. In the early stage (about one week) the cardiac muscle cells which detached from the tissue masses and grew on the glass slide were spherical or short spindle in shape. There were various processes on the surface of the cells. In the middle stage (about two to four weeks) the cells became irregular in shape. The processes extended from the surface of the cells and formed the intercellular connection. In the later stage (more than one month) part of the cells in culture developed and appeared rod shape. The intercellular connection was composed of the intercalated disc-like structure, the rod-shaped cells joined together and formed branched structures. In the development of human fetus in culture a continuous process of the formation of the intercalated disc-like structure was observed. It was found that the developed cells were gradually arranged in bundles running parallel to their long axis. This kind of structure looked like normal mature morphological feature of cardiac muscle cells. It is therefore considered that the cardiac muscle cells in culture may have possibility to differentiate into mature cardiac muscle.

    本文报告用扫描电镜观察体外培养的人胎儿心肌细胞发育的形态特征。材料来自妊娠10、13、16周人胎儿心脏。首先进行组织块培养,然后观察由培养团块上新生并脱离团块贴璧生长的心肌细胞。培养早期(脱落贴壁生长1周左右),细胞呈球形、短梭形,表面有各种突起。中期(脱落生长约2~4周)细胞呈扁平不规则形。细胞间由突起相连接。晚期(脱落生长超过1个月)部分细胞可发育成带状、柱状,由闰盘样结构连接成分支状。体外培养的胎儿心肌细胞,在发育过程中,可见闰盘样结构形成的过程,通过这种连接,使一群细胞相互连接,平行排列成束,近似于成熟心肌细胞的形态及排列。本文研究提示,体外培养的人胎儿心肌细胞似有分化、发育成熟的趋向。
