Spontaneous reversibility of advanced toxic liver cirrhosis

The spontaneous restoration of liver cirrhosis induced by 6 and 9 month CC14 treatment has been studied. The OH-proline content of the liver stroma, the DNA content of the parenchyma, and the Co/DNA ratio were determined. Observations lasted for 4 months after completion of treatment. Cirrhosis developed after 6 month, CC14 administration was reversible in 3--4 months after the discontinuation of treatment; the normal stroma parenchyma ration had gradually normalized. Nine month treatment exhausted the capacity of the stroma for spontaneous recovery and the parenchyma regenerated to a lesser extent. Fibrosis remained practically irreversible 4 months after CC14 administration.
