| Popis: | White pelicans were each given 100 mg of polychlorinated biphenyls (Aroclor 1254) per day for 10 weeks. After the treatment period, the bird's food supply was decreased 50% for 2 weeks. Measurements taken from transmission electron micrographs of the pelican's liver tissue revealed hepatocytes of the treated birds averaged 22% larger in cross-section area than those of controls. The number of vacuoles (lysosomes, microbodies) per hepatocyte was 22% greater. The number of mitochondria per hepatocyte was 25% greater while 25% fewer cristae per mitochondrion were present in treated as compared to control birds. |
