[GH secretion after L-dopa administration in hepatic cirrhosis].

A 500 mg L-Dopa administration in normal and cirrhotic subjects does not determinate a significant varation of plasma glucose and insulin level, while a peak plasma GH level in both cirrhotic and normal subjects occurred at 90' with a significantly greates values in cirrhotics. It is doubtful to affirm that a high plasma GH level is the only one factor which responsable of glucose intolerance in cirrhotic subjects, when there are many others factors contribute to it in synergic way. In order to elucidate the hypothesis on possible pathogenetic mechanism it is discussed some of our own experience and observations.
