摘要: Resume Vingt rats de souche Wistar, porteurs l'hepatome ascitique Yoshida, ont ete soumis a une infusion intraperitoneale, avec solution d'aldehyde L-erythro-α, β-dihydroxybutyrique. Pour l'examen des cellules tumorales au microscope electronique, on preleve echantillons liquide avant et la fin du traitement, ainsi que 2, 4, 6, 24 48 heures apres celui-ci. Les premieres alterations apparaissent traitement; elles se manifestent par formation longues excroissances cytoplasmiques peripherie l'apparition d'une substance tres dense l'interieur vesicules Golgi. Apres ces alterations, constate matrice mitochondriale devient l'espace intracristal dilate; ensuite le membrane exterieure disparait les mitochondries fragmentent. Ces sont evidentes 2 4 traitement. Enfin, observe nucleaires: chromatine condense noyau, tandis granules interchromatiniens groupent dans nucleoplasme. Ensuite, nucleaire fragmente contenu noyau disperse cytoplasme. presentent alors caracteristiques necrose. presentes ascitique, ou peu nombreuses apparemment normales.
