Effects of beta-lactam antibiotics on intestinal microflora and bile acid metabolism in rats.

abstract：:The purpose of the present investigation was to test whether permanent skeletal muscle cells (rat L6 cells) could serve as an in vitro model for alpha-tocopherol (alphaTocH) biodiscrimination studies. L6 cells were incubated in the presence of high density lipoprotein (HDL), low density lipoprotein (LDL), and very low...
