Histological study of the atrioventricular node and bundle in the heart of ovine fetus
This study was conducted on the atrioventricular node (AVN) and atrioventricular bundle (AVB) of fivefour-month-old ovine fetuses. The histological structure of these components was studied by routinehistological techniques and use of specific staining methods. The AVN was caudally located adjacent to theroot of the aorta. It was almost spherical in shape and consisted of twisty cells. The node...
متن کاملUltrastructure of the human atrioventricular node.
Ultrastructure of the A-V node was studied in two human hearts. Fine details of intranodal cellular organization were then resynthesized on the basis of light microscopic examinations of over 250 human hearts. There are four different types of cells and no anatomic syncytium in the human A-V node: (1) a simple rounded cell identical to P cells of the sinus node, (2) a slender transitional cell ...
متن کاملThe dissection of the atrioventricular node, bundle and bundle branches in the human heart.
The A-V node, bundle and bundle branches were grossly dissected in 41 human hearts. The method for this dissection is described. Given also are the sizes of the individual structures with advancing age. These structures grow more slowly than the remainder of the myocardium. T HE dissectability of the A-V node, bundle, and bundle branches in the human heart has been questioned. Retzer1 originall...
متن کاملMolecular Investigation of the Human Adenovirus in Retinoblastoma Patients
Background and Aims: Retinoblastoma tumors are the most common intraocular malignancy in childhood, leading to death after two years. The Human Adenovirus (HAdV) infection could be critical in the retinoblastoma pathogenesis due to the virus and retinoblastoma 1 interactions. The objective of the current study was to investigate the possible presence of the HAdV genome in the retinoblastoma pat...
متن کاملFatal heart block due to mesothelioma of the atrioventricular node.
A fit young man of 23 was symptom free until the time of his death despite a narrow complex complete heart block, with resting heart rates down to 35 beats/min, that was first diagnosed when he was 10. The clinical diagnosis remained congenital heart block. Necropsy showed extensive infiltration of the atrioventricular node and proximal bundle by mesothelioma tissue. Pacing had not been advised...
