The endocardium ultrastructure of 13 embryonic day old hamsters was examined, especially in relationship with the atrial myocytes. The endothelial morphology was described, including the junctional attachments and their relationships with subjacent…
The surface epithelium of 28 gallbladders removed during elective cholecystectomies and pathology collection was studied ultrastructurally. Focusing on 10 of the 28 cases that were diagnosed as cholecystitis, we found that the epithelium displayed…
In view of the lack of sufficient data regarding the morphology of the cystic duct and the extensive focus on the gallbladder, a preliminary examination of the cystic duct response to female sex steroid treatment was conducted to follow up a detailed…
Atrial natriuretic factor (ANF)-immunoreactivity was identified with peroxidase-antiperoxidase staining and immunoelectron microscopic gold labeling techniques in atrial tissues of fetal, newborn and adult Syrian hamsters.
The current study has documented changes in the ultrastructure as well as in the intranucleolar distribution of rDNA and rRNA in RT4 (human transitional cell bladder carcinoma) cell nucleoli following a 3-h exposure to toxic doses of 50 microM…
In the present study we examined the ultrastructural modifications as well as the precise distribution of DNA and RNA in RT4 cell nucleoli following a 3-h exposure to nontoxic or toxic doses of ametantrone (AMT), poly(adenylate-uridylate)…
