Is this correct? Is there any indication of how this "fluid" is involved with the fusion of the amnion and chorion? Thanks for your very interesting and informative input. Terry J.

Terry J DuBose > >--------------------------------------------------------- Terry, >--------------------------------------------------------- Current experience (Dr Jauniaux, UCL, London, UK) suggests that aspiration >--------------------------------------------------------- (transvaginal US and 20G needle, the technique is similar to ovum pick-up) of coelomic fluid is close to 100% between 6-10 weeks. the more viscous coelomic fluid is most probably due to differences in total protein levels between the amniotic and coelomic compartments. Between 6 and 12 weeks the mean level of total protein is 54 times higher in the coelomic cavity than in the amniotic cavity. These observations, in my view, may well be the explanation of the low level echoes in the coelomic cavity. ***************************************************************** The-Hung Bui, M.D. Senior Consultant -- Director, Fetal Diagnosis Programme Department of Molecular Medicine Clinical Genetics Unit Karolinska Hospital S-171 76 Stockholm, Sweden phone: +46 8 517 74989 or 517 72472 (secretary) fax: +46 8 32 77 34 E-mail: The-Hung.Bui@ks.se ****************************************************************** Next message: The-Hung Bui: "Re: Extracoelomic cavity" Previous message: The-Hung Bui: "Re: Extracoelomic cavity"

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
