To study putative teratogenic effects of a T cell-mediated immune response versus an endotoxic challenge , 10-d-pregnant rats received a single intraperitoneal injection of 5 x 10 ( 8 ) human red blood cells ( HRBC ) or gram-negative bacterial endotoxin ( Escherichia coli LPS : 30 micrograms/kg ) .
