Abstract
Pigs deficient in vitamin E and selenium had a decreased contrast of the intracellular membranes compared with pigs supplemented with vitamin E and selenium. Other common changes in the deficient animals included a reduced number of microvilli, with a short and irregular appearance, numerous swollen mitochondria with empty spaces and intercellular oedema. It is suggested that these morphological changes are attributed to the insufficient supply of vitamin E and selenium, though it is not excluded that particular intestinal factors may participate in the development of the lesions.
摘要
与补充了维生素E和硒的猪相比，缺乏维生素E和硒的猪细胞内膜对比度降低。缺乏维生素E和硒的猪的其他常见变化包括微绒毛数量减少，微绒毛短且形态不规则，大量线粒体肿胀且有空泡，以及细胞间水肿。这些形态学变化被认为是由于维生素E和硒供应不足所致，不过也不排除特定的肠道因素可能参与了病变的发展。
