RediHeal Wound Care by Avalon Medical Innovative Veterinary Surgical Products in Stillwater, Minn., is a borate - based
biological glass material that imitates fibrin and traps blood platelets, forming a wound cover to support healing.
The control of
biological material must have been a bit more lax in the late 1970s (maybe cautiousness inversely correlates with lapel width), because she was somehow able to sneak a piece of my (our) umbilical cord to her lab microtome, where she carved two thin sections and mounted them on
glass slides, just for fun.
