The pre-implantation embryos, whose stages were late morula on early blastocyst, were located in the centre of ultrasound beam certainly by using closed microdroplet culture. Experiments were done under various conditions of ultrasound intensity, irradiation time and temperature of circumference. The statistically significant increase of morphological abnormality was observed when 3.0 W/cm2 continuous wave for 60 minutes of 0.65, 1.0 or 1.8 W/cm2 continuous wave for 720 minutes was irradiated. The statistically significant developmental retardation was observed when 2.0 or 3.0 W/cm2 continuous wave for 60 minutes or 0.65, 1.0 or 1.8 W/cm2 continuous wave for 720 minutes was irradiated. Pulsed ultrasound irradiated groups showed neither increase of morphological abnormality nor developmental retardation significantly. The reading of thermistor sonde located in the centre of beam was raised during irradiation. No significant change were observed between warming and irradiated groups, temperature of which were similarly raised. Similar results were seen when 3.0 W/cm2 continuous wave for 60 minutes were irradiated during cool circumference, in which temperature of the centre of ultrasound beam didn't raise more than 37 degrees C. These results suggest that thermal effect of ultrasound is most effective during various effects including cavitation in this study.","PeriodicalId":75398,"journal":{"name":"Acta obstetrica et gynaecologica Japonica","volume":"33 7","pages":"969-78"},"PeriodicalIF":0.0,"publicationDate":"1981-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18315037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Deuterium labeled 3,4,4-d3-DHA, 3,4,4-d3-16 alpha OH-DHA and 2,4-d2-E3 were newly synthesized and highly specific method for determination of serum DHA, 16 alpha OH-DHA and E3 was developed by GC-MS. The mean total steroid concentrations in the third trimester (III), in the stage when patients had irregular contraction (P) and during the first stage of labor (1st) were as follows; DHA, 612.9 +/- 265.3, 877.5 +/- 365.6 and 1522.5 +/- 580.6, 16 alpha OH-DHA, 30.2 +/- 20.2, 49.4 +/- 21.9 and 161.3 +/- 43.6, E3, 50.9 +/0 25.7, 70.4 +/- 19.8 and 108.6 +/- 44.5 ng/ml (mean +/- S.D.). The values of these three steroids increased significantly from the III to the 1st. Correlation between the levels of total DHA and total E2 measured in ten patients individually in the III was 0.8665 (p less than 0.001) which changed to -0.6650 (p less than 0.01) and -0.5362 (p less than 0.05) in the stage of P and 1st. ACTH was given to eight pregnant women in the third trimester, and response of these steroids to ACTH was studied. In addition to these steroids, cortisol (F) levels were also measured by RIA. Following the administration, F increased significantly whereas no changes of DHA, 16 alpha OH-DHA and E3 levels were noticed suggesting that these steroids may not be influenced by maternal adrenal secretion. From the results obtained above, it is suggested that the endocrinological environment in maternal blood as indicated by correlations between DHA and E3 levels, changes prior to the onset of labor.","PeriodicalId":75398,"journal":{"name":"Acta obstetrica et gynaecologica Japonica","volume":"33 7","pages":"935-44"},"PeriodicalIF":0.0,"publicationDate":"1981-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17517582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Serum mean levels of hLH in non pregnant women were 248.5 ng/ml serum before the first injection of LH-RF. The first injection caused an increase in the serum hLH level to 2185.0 ng/ml serum. After the second injection of the hormone, serum hLH levels increased further than the first peak, indicating the \"self-stimulating\" or \"priming\" effect of the first LH-RF on the second peak. Serum mean values of hLH-beta in normal menstrual women were 2.60 ng/ml before the first injection. The hLH-beta response to the second injection was significantly greater than to the first. The first peak of hLH-beta was 4.30 ng/ml serum and the second peak was 5.07 ng/ml serum.

The value of the serum mean levels of hLH-beta during pregnancy were between 0.57 and 0.81 ng/ml and showed no significant increase through two LH-RF stimulations, suggesting that pituitary gonadotropins synthesis and release were depressed during gestation.

Intrauterine resting tonus in 148 primigravid and 74 multigravid women tended to increase towards the onset of labor, with maternal mean blood pressure elevating in close relation to the intrauterine pressure. Especially in primigravid women there was a strong tendency and intrauterine resting tonus was higher value in primigravidas than that in multigravidas. The increasing of intrauterine pressure by uterine contraction caused an elevation of maternal blood pressure by about 10% in pregnant women, and caused a decrease of placental blood flow by about 30% respectively, but it did not show any definite pattern in renal cortical blood flow in experimental animals. On the other hand, the increasing of intrauterine resting tonus with intraamniotic saline injection in 47 cases of experimental animals brought about a decrease of placental blood flow by about 30%, at the same time caused a decrease of renal cortical blood flow by about 20% and an elevation of maternal blood pressure by about 10% respectively. These findings support the concept that increasing of uterine resting tonus could play a role in mediating late pregnancy induced hypertension.","PeriodicalId":75398,"journal":{"name":"Acta obstetrica et gynaecologica Japonica","volume":"33 7","pages":"925-34"},"PeriodicalIF":0.0,"publicationDate":"1981-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18315035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Histological, ultrastructural investigations together with immunofluorescent antibody examinations revealed the following results. Ultrastructurally yolk sac endodermal cells prior to the 7th week of pregnancy were proved to have microvilli, abundant glycogen which formed rosette, parallel arranged rough endoplasmic reticulum (rER), mitochondria closely associated with rER and ovoid electron dense amorphous granules which showed positive diastase-resistant PAS-reaction. Morphologically endoderm after the 8th week of pregnancy showed degenerative changes. Light microscopically the tumors showed Schiller-Duval body, endodermal sinus structure and clear-cells endoblastic pattern, but ultrastructurally the tumor cells of these three types showed approximately similar appearances. Ultrastructural features of the tumor seem to resemble those of the yolk sac endoderm before the 7th week of pregnancy. The tumor cells which form the epithelial mantling of Schiller-Duval body closely resembled the endodermal cells facing the yolk sac cavity with respect to the presence of abundant glycogen granules, rER, mitochondria, short irregular microvilli on the cell surface and remarkable nucleolus with thread-like nucleolonema. Both the tumor cells facing the endothelial cell and those which form the endodermal sinus structure and clear-cells endoblastic pattern resembled the endodermal cells facing the mesenchyma in view of the features of intracellular organelles, the presence of extracellular basement membrane-like substances and tubular structure.","PeriodicalId":75398,"journal":{"name":"Acta obstetrica et gynaecologica Japonica","volume":"33 7","pages":"916-24"},"PeriodicalIF":0.0,"publicationDate":"1981-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17236825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
