[Angioarchitecture of gliomas. 1: Models of cerebral vessels, casting materials, preparation methods, changes in...

A report is given on the study of cerebrovascular systems in experimental animals and corpses and the demonstration of cerebral tumours be means of models of vascular system. After a survey of the development of model representation, the technique of the vessel injection, the various injection materials and methods of preparation are described in detail. Advantages and disadvantages of the individual methods and certain peculiarities in model representations of transplantation tumours and various human brain tumours are presented. Besides, a multitude of pictures which document the results of the experiments, general laws of the tumour development, angioarchitectufe of the cerebral tumours and the changes in pre-existing and newly formed vessels in and around the tumour are briefly dealth with. The individual results of systematic investigations into the vascular system of cerebral tumours--of human brain vessel models, of transplantation tumours and special angioarchitecture of gliomatous brain tumours--will be published in individual articles appearing later.
