Our purpose was to determine whether the measurement of hCG levels in vaginal fluid is useful for the diagnosis of premature rupture of membranes(PROM). 81 pregnant women participated in the study. Second trimester(12 cases) and third trimester normal pregnant women(40 cases) who had no evidence of placenta previa, premature rupture of membranes(PROM) or preterm labor were enrolled in the control group. Consenting patients(n=29) with complaint membrane rupture between second and third trimester of gestation who had no evidence of placenta previa or labor were enrolled in the study group. The diagnosis of membrane rupture required at least two of the following findings on vaginal examination: vaginal pooling of fluid, positive Nitrazine paper test, or positive fetal fibronectin test. As this results, confirmed PROM group(18 cases) and suspicious PROM group(11 cases) is divided. After irrigating the posterior vaginal fornix with 3 mL of sterile saline, we measured hCG levels. Data analysis included Fisher-Exact test, χ² test, t-test. The mean and standard deviation of vaginal fluid hCG level of normal pregnant women were 43.08±42.61, 21.60±22.63 mIU/mL during the second and third trimesters, respectively. That of women with confirmed PROM and suspicious PROM were 565.5±884.23, 12.73±7.64 mIU/mL, respectively. Using a hCG threshold value of 50 mIU/mL, sensitivity was 83.3%, specificity 66.7%, positive predictive value 78.9%, negative predictive value 72.7%, accuracy 76.7% between the second trimester normal control and confirmed PROM group; and sensitivity was 83.3%, specificity 95.0%, positive predictive value 88.2%, negative predictive value 92.7%, accuracy 91.4% between the third trimester normal control and confirmed PROM group; sensitivity was 83.3%, specificity 100%, positive predictive value 100%, negative predictive value 78.6%, accuracy 89.6% between confirmed and suspected PROM group. The hCG level in the vaginal fluid is a useful additive marker of PROM during third trimester when the rupture is only suspected.

Objective: This research investigated the effects of human chorionic gonadotropin (HCG)-producing peripheral blood mononuclear cells (PBMCs) on the implantation rate and embryo attachment in mice. Methods: In this experimental study, a DNA fragment of the HCG gene was cloned into an expression vector, which was transfected into PBMCs. The concentration of the produced HCG was measured using enzyme-linked immunosorbent assay. Embryo attachment was investigated on the co-cultured endometrial cells and PBMCs in vitro. As an in vivo experiment, intrauterine administration of PBMCs was done in plaque-positive female mice. Studied mice were distributed into five groups: control, embryo implantation dysfunction (EID), EID with produced HCG, EID with PBMCs, and EID with HCG-producing PBMCs. Uterine horns were excised to characterize the number of implantation sites and pregnancy rate on day 7.5 post-coitum. During an implantation window, the mRNA expression of genes was evaluated using real-time polymerase chain reaction. Results: DNA fragments were cloned between the BamHI and EcoRI sites in the vector. About 465 pg/mL of HCG was produced in the transfected PBMCs. The attachment rate, pregnancy rate, and the number of implantation sites were substantially higher in the HCG-producing PBMCs group than in the other groups. Significantly elevated expression of the target genes was observed in the EID with HCG-producing PBMCs group. Conclusion: Alterations in gene expression following the intrauterine injection of HCG-producing PBMCs, could be considered a possible cause of increased embryo attachment rate, pregnancy rate, and the number of implantation sites.

The incidence of uterine arteriovenous malformation (AVM) is rare. However, it is clinically significant in that it can cause life-threatening vaginal bleeding. We report a case of a large uterine AVM with positive serum beta-human chorionic gonadotropin. A presumptive diagnosis was made; a uterine AVM accompanied by, early pregnancy or retained product of conception. Because this uterine AVM was extensive, transcatheter arterial embolization of both uterine arteries and extra-uterine feeding arteries was performed. Three months after undergoing transcatheter arterial embolization, complete resolution of the uterine AVM was confirmed without major complication.

Maghraby, Hassan Ali,Agameya, Abdel Fattah Mohamed,Swelam, Manal Shafik,El Dabah, Nermeen Ahmed,Ahmed, Ola Youssef The Korean Society for Reproductive Medicine 2022 Clinical and Experimental Reproductive Medicine Vol.49 No.2

Objective: This study investigated the impact of two stimulation protocols using highly purified human menopausal gonadotropin (HP-hMG) on the endocrine profile, follicular fluid soluble Fas levels, and outcomes of intracytoplasmic sperm injection (ICSI) cycles. Methods: This prospective clinical trial included 100 normal-responder women undergoing ovarian stimulation for ICSI; 55 patients received concomitant follicle-stimulating hormone (FSH) plus HP-hMG from the start of stimulation, while 45 patients received FSH followed by HP-hMG during mid/late follicular stimulation. The primary outcome was the number of top-quality embryos. The secondary outcomes were the number and percentage of metaphase II (MII) oocytes and the clinical pregnancy rate. Results: The number of MII oocytes was significantly higher in the concomitant protocol (median, 13.0; interquartile range [IQR], 8.5-18.0 vs. 9.0 [8.0-13.0] in the consecutive protocol; p=0.009); however, the percentage of MII oocytes and the fertilization rate were significantly higher in the consecutive protocol (median, 90.91; IQR, 80.0-100.0 vs. 83.33 [75.0-93.8]; p=0.034 and median, 86.67; IQR, 76.9-100.0 vs. 77.78 [66.7-89.9]; p=0.028, respectively). No significant between-group differences were found in top-quality embryos (p=0.693) or the clinical pregnancy rate (65.9% vs. 61.8% in the consecutive vs. concomitant protocol, respectively). The median follicular fluid soluble Fas antigen level was significantly higher in the concomitant protocol (9,731.0 pg/mL; IQR, 6,004.5-10,807.6 vs. 6,350.2 pg/mL; IQR, 4,382.4-9,418.4; p=0.021). Conclusion: Personalized controlled ovarian stimulation using HP-hMG during the late follicular phase led to a significantly lower response, but did not affect the quality of ICSI.

Objective : Our purpose was to determine the association between unexplained elevation of maternal serum human chorionic gonadotropin (hCG) in the second trimester and adverse pregnancy outcomes. Material and methods : Between February 1995 and July 1999, we evaluated 1566 pregnant women who have underwent second trimester triple marker screening tests (alpha-fetoprotein, unconjugated estriol, human chorionic gonadotropin) and delivered at Severance Hospital, Yonsei Medical Center. Multiple pregnancies, abnormal fetal karyotypes, fetal anomalies, and abortions were excluded from the study. One hundred twenty-one women with hCG levels greater than 2.0 multiples of the median (MoM) were included in the study group while 1389 women with hCG levels less than 2.0 MoM served as the control group. Pregnancy outcomes were obtained from the delivery and neonatal records in our institution. Adverse pregnancy outcomes between the two groups were compared using chi-square test and Fisher's exact test. Results : Women with unexplained elevation of human chorionic gonadotropin levels were associated with statistically significant increased risks for preeclampsia, preterm delivery, and low birth weight (p<0.05). However, there were no significant differences between the study and control groups with respect to preterm premature rupture of membranes, abnormal fetal heart rate tracing, abruptio placentae, intrauterine fetal death, and neonatal death. Conclusion : An unexplained elevation in human chorionic gonadotropin level in the second trimester may increase the risk for preeclampsia, preterm delivery, and low birth weight but not for other adverse pregnancy outcomes such as preterm premature rupture of membranes, abnormal fetal heart rate tracing, intrauterine fetal death, or neonatal death.

Objective: This study was designed to evaluate whether maternal serum human chorionic gonadotropin(hCG) level measured during second trimester could be used as a predictor of pregnancy-induced hypertension. Methods: Between March 1996 and November l997, 505 pregnant women undergoing second trimester(14-22 weeks of amenorrhea) triple marker screening for neural tube defect and Down syndrome who delivered at our institution were reviewed. All samples were assayed in the same laboratory and medical records were reviewed about medical and obstetrical history. Results: Maternal serum human chorionic gonadotropin level(multiples of the median, MoM) was significantly higher in the pregnancy-induced hypertension group than in the control group. With the use of 2. l multiples of the median as a cutoff value, the sensitivity of human chorionic gonadotropin as a screening marker for development of pregnancy-induced hypertension was 38.7%, the specificity was 95.9%, positive predictive value was 38.7% and negative predictive value was 95.9%. Conlusion: We suggest that second trimester maternal serum human chorionic gonadotropin levels can be used clinically as an early predictive marker for pregnancy-induced hypertension.

For the evaluation of hormonal control of sperm in cultured fish a method to quantify the spermiation response of mature flatfish to hormonal therapy is described. Spermatocrit was determined after 30 min. in centrifuge condition of 12,000rpm. Sperm density was estimated by a standard hemacytometer method. However, sperm density can be predicted from spermatocrit since their relationship is linear as described by the re-gression equation. Y=1.14X-0.04 (r=0.91. P<0.0001. n=50), where Y is spermatocrit and X is sperm density. Sperm density levels ranged from 21.5 to 98.4×10^(4) spermatozoa per ㎕ milt corresponding to spermatocrit values of 12 to 95%. Milt production by mature flatfish was highest (7.4ml per kg body weight) at 24h after injection of 1,000IU of human chorionic gonadotropin(HCG) per kg body weight and coincided with low spermatocrit (63%) and sperm density (67.4×10^(4) spermatozoa per ㎕ milt) levels. No significant differences was appeared in milt production, spermatocrit and sperm density between control and HCG-treated fish at 48h after HCG injection. These results demonstrate that spermiation in mature flatfish can be reliably evaluated by a spermatocrit method and that HCG is effective in stimulating of spermiation in this species.

넙치(Paralichthys olivaceus)에서 호르몬 처리에 의한 효과적인 인공산란 연구의 일환으로 human chorionic gonadotropin(HCG)에 의한 성숙 넙치에서의 spermatocrit법에 의한 배정(spermiation)효과를 연구하였다. 안정된 spermatocrit치를 위한 정액의 분획조건은 12,000rpm, 30분간의 원심분리가 적절하였으며 spermatocrit(Y)는 정자밀도(X)와는 Y=1.14X-10.04(r=0.91, P<0.0001, n=50)의 관계식을 나타내었다. 정자밀도는 21.5∼98.4×10??정자/㎕정액으로 12∼95%의 spermatocrit치에 해당하였다. 성숙넙치의 정액생산은 1,000IUHCG/㎏BW의 주사시 24시간후에 가장 높았고(7.46㎖/㎏BW), 낮은spermatocrit치(63%)와 낮은 정자밀도(67.4×10??정자/㎕정액)수준과 일치하여 정액점도는 매우 낮게 나타났다. 이와같은 낮은 정액점도는 HEG처리에 의한 정소의 수화(hydration)에 기인된 것으로 여타 lobular형 정소에서의 호르몬 처리시 결과와 일치하였다. 48시간후의 HCG처리군과 대조군간의 정액생산, spermatocrit치 및 정자밀도에서는 유의한 차이를 보이지 않았다. 본 연구결과 성숙넙치의 배정은 spermatocrit법에 의해 명확히 판별될 수 있으며 HCG는 본 종에서 배정을 효과적으로 촉진시킬 수 있음이 나타났다.

Development and Immunochemical Properties of Two Monoclonal Antibodies Specific to Human Chorionic Gonadotropin

Kim, You-Hee,Koh, Kwan-Sam Korean Society for Biochemistry and Molecular Biol 1999 Journal of biochemistry and molecular biology Vol.32 No.5

Using a hybridoma technique, spleen cells of Balb/c mice immunized with human chorionic gonadotropin (hCG) were fused with NS-1 mouse myeloma cells. Two hybrid cell lines, clones KS-8 and KS-19, secreting monoclonal antibodies to hCG, were isolated. KS-8 and KS-19 belong to the immunoglobulin $G_1$ subclass. With the aid of a double-antibody radioimmunoassay, it was established that the KS-8 monoclonal antibody recognizes an immunodeterminant of the $\beta$-subunit of hCG, whereas the KS-19 monoclonal antibody recognizes an epitope present on the $\alpha$-subunit of hCG. The KS-8 monoclonal antibody specifically reacts with human chorionic gonadotropin and shows cross-reactivity of less than 0.3% to other related human glycoprotein hormones. On the other hand, using a hemagglutination test based on antibody-induced agglutination of sheep red blood cells coated with hCG, It was shown that only the KS-19 monoclonal antibody was capable of inducing a positive reaction, although both monoclonal antibodies had similar binding capacity to the coated cells. The results from the dual screening procedures demonstrate that KS-8 and KS-19 monoclonal antibodies show high sensitivity in two different assays, and are hence useful for the qualitative and quantitative determination of hCG by both radioimmunoassay and hemagglutination inhibition tests.
