Vascular arrangement in the oral mucosa of Rana esculenta. Scanning electron microscopy of corrosion casts.

Scanning electron microscopy of vascular corrosion casts--standard method for studying microvessels.

Scanning electron microscopy (SEM) of vascular corrosion casts (microvascular corrosion casting/SEM method) is a standard method, which allows three-dimensional visualization with good resolution of the normal and abnormal microvessels, including the capillaries of various organs and tissues. SEM of vascular corrosion casts can obtain qualitative as well as quantitative informations important t...

Porcine liver vascular bed in Biodur E20 corrosion casts.

BACKGROUND Pigs are frequently used as animal models in experimental medicine. To identify processes of vascular development or regression, vascular elements must be recognised and quantified in a three-dimensional (3D) arrangement. Vascular corrosion casts enable the creation of 3D replicas of vascular trees. The aim of our study was to identify suitable casting media and optimise the protocol...

L6-3 Scanning Electron Microscopy of Vascular Corrosion Casts and 3D-Morphometry – State-of-the-Art and Perspectives

Maturation of the gastric microvasculature in Xenopus laevis (Lissamphibia, Anura) occurs at the transition from the herbivorous to the carnivorous lifestyle, predominantly by intussuceptive microvascular growth (IMG): a scanning electron microscope study of microvascular corrosion casts and correlative light microscopy

The microvascular bed of the stomach of Xenopus laevis and the changes it undergoes when the herbivorous tadpole becomes a carnivorous adult were studied by scanning electron microscopy of vascular corrosion casts and light microscopy of stained tissue sections. In tadpoles an upper and a lower gastric artery supplied, and upper, middle and lower medial and lateral gastric veins drained the ver...

Renal microcirculation of the bullfrog, Rana catesbeiana. A scanning electron microscope study of vascular casts.

The microcirculation of the bullfrog kidney was studied by scanning electron microscopy of the corrosion casts. The bullfrog kidney derives its blood supply from a dual origin: one is from the posterior half of the body via the renal portal veins and the dorso-lumbar veins, the other is from the urogenital arteries. The renal portal veins are linked with the hepatic portal system through the an...
