31. Methods 157 samples of chorionic villus in early pregnancy were analyzed by cytogenetic method.

32. Conclusion:Early detection of intramural pregnancy with the use of transvaginal ultrasound(TVS) and monitoring of serum human chorionic gonadotropin(HCG) is important.

33. There is a sudden rise of a hormone called human chorionic gonadotrophin during early pregnancy, which controls the production of other pregnancy hormones.

34. At present, the diagnosis of DS mainly depends on cytogenetic analysis through amniocentesis, chorionic villus sampling or puncture of umbilical vein to recovery fetal cell.

35. Confirmation with chorionic villus sampling ( CVS ), amniocentesis or other testing is still necessary.

36. Objective The aim of this study was to investigate the effect of luteinizing hormone and human chorionic gonadotropin on in vitro maturation of oocytes of Kunming mice.

37. Human chorionic gonadotropin ( hCG ) is a glycoprotein hormone.

38. The amniotic cavity, which is initially located dorsal to the germinal disk, grows rapidly and eventually encircles the fetus, obliterates the chorionic cavity, and envelops the umbilical cord.

39. A new method for the preparation of highly potent crude human chorionic gonadotropin of pregnancy urine is reported.

40. Serum alpha - fetoprotein ( AFP ) and beta - human chorionic gonadotropin ( ? ? - HCG ) levels were elevated.

41. Examples of diagnostic tests include amniocentesis and chorionic villus sampling.

42. For pregnancies at increased risk for nephropathic cystinosis, prenatal testing is also available biochemically, based upon elevated cystine concentration in both chorionic villi and amniocytes.

43. Objective: To investigate the content of NO, the activity of NOS in serum and chorionic villus, the content of VEGF in serum of recurrent spontaneous abortion (RSA) and control group. Sentencedict.com

44. Invasive prenatal diagnostic techniques include amniocentesis, chorionic villus sampling(CVS), fetal blood sampling and embryoscopy. In this article, we introduced the procedures of these met...

45. Objective To investigate the effect of human chorionic gonadotrophin on matrix metalloproteinase-19 (MMP-19) mRNA expression in trophoblasts.

46. Methods Decidua and chorionic tissues of 20 patients with spontaneous abortion (AP group) and 20 women with normal pregnancy (NP group) were collected.

47. When fertilized eggs implanted in the womb, pregnant women will produce a new hormone, called human chorionic gonadotropin, its function is to maintain pregnancy.

48. Objective: To find out the effect of human chorionic gonadotrophin on the invasiveness of trophoblast.

49. Human chorionic gonadotropic (hCG) and human placental latogen (hPL) are peptide hormones produced and excreted by placental trophoblastic cells during pregnancy.

50. Objective To investigate the DNA damage in human early chorionic villus cells in uterus induced by diagnostic ultrasonography.

51. Objective To discuss the comparability of human chorionic gonadotropin (HCG) results among different detection system.

52. We discovered that CAM EC on day 8,10, and 12 after incubation localized beneath the chorionic ectoderm, but with the age growing, EC gradually migrated toward ectoderm from mesenchyme.

53. Objective To evaluate the reliability of the dot gold immunofiltration assay (DGIFA) for quantitative determination of human chorionic gonadotropin (HCG) in serum or urine.

54. Do We Need to Follow Up Complete Miscarriages With Serum Human Chorionic Gonadotrophin Levels?

55. Objective To establish the analysis method of chorionic trophocyte chromosomes and its application in study of early spontaneous abortion etiology.

56. Methods The PCO rat models were established by pregnancy hormone combined with human chorionic gonadotrophin.

57. Sometimes it's an earlier test called CVS, or chorionic villus sampling, which collects a bit of tissue from the placenta.

58. As soon as a woman conceives, the embryo secretes human chorionic gonadotrophin or hCG, the hormone we check for in pregnancy tests.

59. Objective:To explore the primary culture method of human chorionic and decidual tissues in vitro and to study their growth regular.

60. Objective In order to explore the value of diagnosis ectopic pregnancy by HCG(human chorionic gonadotropin) qualitative analysis with urine HCG test paper in serum of abdomen cavity.
