to test for the possible existence of a direct cytotoxic action of pq on endothelial cells , we have studied , for up to 5 days , the action of 10 ( -6 ) to 10 ( -4 ) m pq on primary cultures of pig aortic endothelial cells and compared these effects to those obtained with exposure to 95 % o2-5 % co2 .
