Abstract
  1. The feeding of 0.5% (3,5,5-trimethylhexanoyl)ferrocene (TMH-ferrocene) in rats resulted in a severe and progressive liver siderosis (total liver iron, 30 mg/g liver wet weight, after 30 weeks). 2. High concentrations of an iron-rich ferritin (up to 250 mg/l) were detected in serum of heavily iron-loaded rats forming a large fraction of non-transferrin-bound-iron (5000 micrograms/dl in maximum). 3. Ferritin and not haemosiderin was the major iron storage protein in the liver. 4. The total liver iron concentration (from 0.4 to > 30 mg Fe/g wet wt) but not the cytosolic low-molecular-weight-iron fraction (from 0.5 to 2.5 microM) was extremely increased during iron-loading.
摘要
  1. 给大鼠喂食0.5%(3,5,5-三甲基己酰基)二茂铁(TMH-二茂铁)会导致严重且进行性的肝脏铁沉着症(30周后肝脏总铁含量为30毫克/克肝脏湿重)。2. 在铁负荷严重的大鼠血清中检测到高浓度的富含铁的铁蛋白(高达250毫克/升),其构成了非转铁蛋白结合铁的很大一部分(最高达5000微克/分升)。3. 铁蛋白而非含铁血黄素是肝脏中的主要铁储存蛋白。4. 在铁负荷期间,肝脏总铁浓度(从0.4毫克铁/克湿重增至>30毫克铁/克湿重)极度升高,但胞质低分子量铁组分(从0.5微摩尔至2.5微摩尔)并未升高。
