Experimental Methods and Clinical Examination Techniques

Abstract

Anatomical investigative techniques for the spinal vascular system are based upon preparations using macroscopic-microscopic inspection, histological serial sections and numerous methods of vascular injection. The latter are especially valuable for demonstrating continuous vessel courses. In addition to non-hardening staining fluids such as ink, usually mixed with gelatin (Bolton, 1939; Herren and Alexander, 1939; Suh and Alexander, 1939; Gillilan, 1958; Corbin, 1961; Vuia and Alexaniu, 1969), many hardening substances were used as well. Adamkiewicz (1881) and Kaydi (1889) injected stained glutin and a Teichmann cement of chalk and linseed oil. Other notable substances are PANSCH-mass (Noeske, 1958; Roll, 1958), celloidin (Bolton, 1939), latex solution (Gillilan, 1958; Clemens, 1961; Jellinger, 1966a; Domisse, 1975) or neoprene latex solution (Perese and Fracasso, 1959), synthetic resin (Lazorthes, 1958; Corbin, 1961) or polymerized plastics such as plastoid (Gillilan, 1958; Piscol, 1972). These and other substances which harden out well facilitate corrosive preparations after maceration in potassium hydroxide solution.
