| Abstract: | To clarify the factor(s) responsible for changes in the plasma cyclic GMP concentration in liver diseases, we measured the plasma levels of cyclic GMP, along with cyclic AMP, in various clinical stages of chronic liver diseases and acute hepatitis. The level of cyclic GMP was found to increase significantly in the early stage of acute hepatitis, in the decompensated stage of liver cirrhosis, and in malignant diseases. In the former two states, it is postulated that decreased hepatic mass is responsible for the changes in the plasma cyclic GMP concentration. The retention rate of indocyanin green (ICGR15) was highly correlated with the plasma cyclic GMP level. The result suggests that the determination of plasma cyclic GMP is useful as an index of the reserve function of the liver in disease states. |
