These lecithin levels were statistically compared with the levels in a control (Wilcoxon test). It emerged that the lecithin levels in the long-term beta-mimetic therapy group were significantly lower, i.e., from 33/0 to 39/6 (33/0-34/6, p less than 0.05; 35/0-39/6, p less than 0.01). The answer to the question how often levels occur in the long-term group which are below the as critical described level of 3 mg Lec/100 ml amniotic fluid appears to be clinically important. It is shown that values below the critical level from 33/0 to 39/6 are much more frequent in the long-term beta-mimetics therapy group than in the control group. There is no known explanation for this. It was concluded that the application of beta-mimetics in cases of long-term tocolysis should only be discontinued when the lecithin content of the amniotic fluid lies above the critical limit of 3 mg Lec/100 ml.</p>","PeriodicalId":75889,"journal":{"name":"Gynecologic investigation","volume":"9 4","pages":"205-9"},"PeriodicalIF":0.0,"publicationDate":"1978-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000300985","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11949707","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}

Following observations of normal transport, muscular activity of the ampulla was inhibited pharmacologically with Acepromazine, a preanesthetic tranquilizer. With muscle contractions blocked, egg transport continued but in a dramatically altered fashion; in the final two thirds of the ampulla the motion changed from rapid to-and-fro movements to a slow uniform prouterine movement which was attributed to ciliary activity. However, the net velocity of transport did not change when the smooth muscle was inhibited indicating that muscle contractions are at least unnecessary and perhaps ineffective for ampullary egg transport in the rabbit.","PeriodicalId":75889,"journal":{"name":"Gynecologic investigation","volume":"7 5 1","pages":"306-20"},"PeriodicalIF":0.0,"publicationDate":"1977-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1097/00006254-197708000-00015","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"61917684","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}
