title: [Quantitative analysis of the expression of insulin receptor and tyrosine protein kinase of patients with hepatic cirrhosis].
abstract: OBJECTIVE
  To investigate the relationship between the expression of insulin receptor (IR) and the content of tyrosine protein kinase (TPK) in patients with hepatic cirrhosis.
  
  
  METHODS
  Glucose tolerance test (GTT), insulin, c-peptide, insulin antibodies in serum, the expression of IR and TPK were quantitively analysed in patients with hepatic cirrhosis. The amount of IR and TPK was evaluated by immunohistochemical quantitative analysis using image analyzer in 12 patients with positive HBV marks and cirrhosis. Insulin and c-peptide in serum were determined by immunoenzymemetric assay (IEMA) and insulin antibodies in serum determined by RIA.
  
  
  RESULTS
  IR amount in normal and abnormal GTT patients with hepatic cirrhosis was signifficantly less than that in control group (P<0.01). TPK amount in liver of patitents with abnormal GTT was less than that of normal GTT (P<0.01).
  
  
  CONCLUSIONS
  IR decreases in cirrhotic patients. Abnormal GTT has relation to reducing TPK activity.
