A testing system of medicine with bio artificial liver

摘要

A drug testing system using any number of bio-artificial organs, for example liver-slices based in a culture apparatus. The apparatus has a chamber with plasma and gas valves, animal organ slices being positioned securely in the chamber so as to maximize the surface area of organ slices exposed to the culture medium. Plasma is supplied to the chamber so that it rises to contact the organ slices, and is alternately removed from contacting the organ slices. Gas is supplied to the top of the chamber. The system also includes a reservoir for containing media entering and exiting the chamber. Methods are provided for assessing the toxicity of a drug or drug candidate.
