Re: Hot flashes/phytoestrogensFrom: Terrence.Jones@ncal.kaiperm.orgThu Jan 30 21:17:42 1997
"Kinch" (One of the Heroes?), I'm no ophthalmologist - but did you pluck Voltaire's 'I' out? Our pharmacy is compounding from sources similar to Bryan's - i.e. from isoflavone in soybean. Our source is Pharma-Tek (NY), who I'm told are supplied by UPJOHN (so I guess we won't be having any Industry-supported clinical trials to facilitate FDA approval). An additional source of micronized powder for doses in HRT (200-400mg/day) is Paddock Labs (Minn). As you mentioned, mammalian enzyme systems currently employed are unable to perform the conversion :) . However, that does not discount a potential value of soy/miso protection of certain other conditions -- particularly genistein and certain neoplastic tendencies (Barnes, J Nutr 3/95, 125 (suppl 3):777s-783s. Watch over the next year for more definitive studies on soy-based isoflavones and preferential susceptibility of neoplastic cells to tyrosine kinase inhibition. Meantime, can maybe someone invent a form of tofu that tastes any better? Right now it ranks a close second to metamucil! <--which bring up the issue of diminished progesterone absorption secondary to high dietary fibre.....Y'all wanna' pass that granola :) tj. --------------------------( Enclosure 1 follows )---------------------------- Date: Sunday, 26 January 1997 1:04pm --------------------------( Enclosure 1 follows )---------------------------- From: lkinchel@icnet.net (Kinch) --------------------------( Enclosure 1 follows )---------------------------- Subject: Re: Hot flashes/phytoestrogens Sender: ob-gyn-l@obgyn.NET To: Multiple recipients of list <ob-gyn-l@talk.obgyn.NET> Errors-to: ob-gyn-l-request@obgyn.NET Precedence: bulk Originator: ob-gyn-l X-Comment: list for discussion of obstetrics and gynecology X-Listprocessor-version: 6.0c -- ListProcessor by Anastasios Kotsikonas Reply-To: lkinchel@icnet.net
Yams contain pure natural
>estrogen and progesterone, and yam extract is available in health-food
Bryan S. Jick, M.D., F.A.C.O.G.
>Pasadena, CA Bryan, I would agree with everything you said EXCEPT the above quote about Yams and natural progesterone. Most natural progesterone is made from Diosgenin, a plant sterol that is found in large amounts in the Mexican Yam. Manufactors convert Diosgenin to the identical progesterone that the body produces. Plain Mexican Yams containonly Diosgenin which the body can not convert to progesterone. It is like trying to put crude oil in your car and expecting it to run like gasoline. This Yam crean stuff that people are selling by the tons is another way that the good solid evidence of CAM gets distorted by those wanting to make a buck.

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.
