Changes In The Esophageal Epithelium In Rabbits Treated By Cis-Dichlorodiammineplatinum As Studied By Electron Microscopy, M. Albertsson, C. -H. Hakansson, M. Palmegren Nov 1989

Changes In The Esophageal Epithelium In Rabbits Treated By Cis-Dichlorodiammineplatinum As Studied By Electron Microscopy, M. Albertsson, C. -H. Hakansson, M. Palmegren

Scanning Microscopy

The esophageal mucosa of the rabbit was investigated after a single dose of 5 mg Cis-Dichlorodiammineplatinum (Cis-DDP). Specimens were taken for scanning electron microscopy, transmission electron microscopy, and light microscopy. Examination was performed daily for 20 consecutive days. A cytotoxic effect was observed already the first day after injection with an intracellular oedema. Thereafter the height of the esophageal epithelium and the basal cell layer steadily decreased to a minimum day 11. This parallels the damaged microridges and an increased cell loss as revealed by scanning electron microscopy. At the end of the observation period the esophageal mucosa had completely …


The Effect Of 10 And 20 Gy Single Dose Irradiation On The Esophageal Mucosa Of The Rabbit. An Electron Microscopic Study, C. H. Hakansson, M. Albertsson, M. Palmegren Nov 1989

The Effect Of 10 And 20 Gy Single Dose Irradiation On The Esophageal Mucosa Of The Rabbit. An Electron Microscopic Study, C. H. Hakansson, M. Albertsson, M. Palmegren

Scanning Microscopy

The mucosa of rabbit esophagus was irradiated with single doses of 10 and 20 Gy respectively. Specimens were taken for scanning electron microscopy (SEM), and light microscopy investigations. Examinations were made 1-14 days after 10 Gy and 1-17 days after 20 Gy. Irradiation resulted in edema during the first days. The thickness of the epithelium was at its lowest value around day 5 after the administration of 10 Gy, and on days eight to ten after the administration of 20 Gy. Damage of the epithelium surface, as scored on SEM micrographs, was most pronounced on days eight to eleven after …


Esophageal Vasculature In The Guinea Pig: A Scanning Electron Microscope Study Of Vascular Corrosion Casts, S. Aharinejad, P. Franz, A. Lametschwandtner, W. Firbas Aug 1989

Esophageal Vasculature In The Guinea Pig: A Scanning Electron Microscope Study Of Vascular Corrosion Casts, S. Aharinejad, P. Franz, A. Lametschwandtner, W. Firbas

Scanning Microscopy

The esophageal vascularization of adult male and female albinotic Guinea pigs (Cavia porcellus) is studied by means of light microscopically evaluated serial sections and by scanning electron microscopy (SEM) of vascular corrosion casts. Bronchoesophageal artery (cervical portion), direct branches of tha aorta, recurrent branches of the intercostal arteries (thoracic portion) as well as of the left gastric artery (abdominal portion) supply the esophagus; internal jugular vein, inferior thyroid vein (cervical portion), azygos vein, intercostal veins (thoracic portion) and portal vein, gastroepiploic vein and cranial pancreatoduodenal vein (abdominal portion) drain it. Longitudinally arranged arterioles, venules and capillaries lying at …
