Executive Director of the Nevada State Athletic Commission, Marc Ratner and Chief Deputy Attorney General, Keith E. Kizer confirmed to ADCC that, ?Nathan Marquardt‘s drug test came back positive for nandrolone metabolite.? According to Ratner, Marquardt will be sent a letter and he will have a chance to appeal. Ivan Salaverry, the other participant in the Ultimate Fight Night?s main event, was the only other fighter to be tested that night and his test came back clean.Paul May, of the School of Chemistry in the University of Bristol defines the drug known as nandrolone (also known commercially as Deca-Durabolin) has the IUPAC name 17b-hydroxy-19-nor-4-andro-sten-3-one, and is an anabolic steroid (a muscle-building chemical) which occurs naturally in the human body, but only in tiny quantities. It is very similar in structure to the male hormone testosterone, and has many of the same effects in terms of increasing muscle mass, without some of the more unwanted side-effects such as increased body hair or aggressive behavior. As such, it is being actively examined in clinical tests as a possible treatment for wasting diseases, and to strengthen and increase body tissue and musculature in HIV infected men. In this form it is usually injected in its decanoate form, after first being dissolved in a suitable edible oil.Here is the breakdown of the medical suspensions from State of Nevada Athletic Commission:Chris Leben, who won a split decision against Patrick Cote, is suspended until his left thumb is cleared by an orthopedic doctor and his left ear is cleared by ENT doctor. If these matters aren?t taken care of, Leben will suspended until February 3 2006.Sam Hoger, Pete Sell, Gideon Ray and Drew Fickett are all suspended until September 6 2005, with no contact until August 28, 2005.Alex Karalexis must have his nose and right ribcage x-rayed to rule out a fracture or he can not compete until February 3 2006.
