нашла таки, очень похоже, эта вторичная циркуляция называется "enterohepatic circulation", вот выдержка, ссылка внизу:
" ... This "waste disposal" system starts in your liver, which continuously filters your blood. As blood passes through the liver's network of tiny capillaries, liver cells remove toxins, cholesterol, medications, waste hormones, and whatever else your body figures it is better off without. These undesirables are then sent from the liver into a small tube, called the bile duct, which leads to your intestinal tract. There, fiber soaks up these chemicals and carries them out with the wastes. Now, there is plenty of fiber in vegetables, fruits, beans, and whole grains. So if these are a big part of your diet, your "waste disposal" system works pretty well. The liver pulls hormones out of the bloodstream, they slide down the bile duct, fiber picks them up, and out they go. But what happens if your lunch consisted of a chicken breast and a cup of yogurt? These products don't come from plants—and that means they have no fiber at all. Not a speck. So when your liver sends hormones or other chemicals into the intestinal tract, there is nothing for them to attach to. They end up being reabsorbed back into your bloodstream, and the whole process starts over again. This endless cycle—hormones passing from the bloodstream, through the liver, into the intestinal tract, and, unfortunately, back into the bloodstream—is called enterohepatic circulation. It keeps hormones circulating for longer than they should. Fiber stops this cycle by carrying hormones out once and for all. " http://www.cancerproject.org/resources/handbook/section2.pdf |

спасибо, я сейчас сама почитаю, давно не доводилось по-английски. про печень - да, именно она вырабатывает подобные ферменты. но мне казалось что гормоны не должны уничтожаться при первом же попадании в печень... это как-то нелогично.

ага, это уже более понятно. спасибо! не объяснили только, расщепляет ли в самом деле печень гормоны или нет... Если "hormones circulating for longer than they should"?
