title: [The influence of epidermal growth factor, neurotensin on cytosolic calcium and membrane fluidity in carbon tetrachloride-injured primary cultured hepatocytes].
abstract: OBJECTIVE
  To study the influence of epidermal growth factor (EGF), neurotensin (NT) on cytosolic calcium and membrane fluidity in carbon tetrachloride-injured primary cultured hepatocytes.
  
  
  METHODS
  A micro-model of carbon tetrachloride -induced primary cultured hepatocytes injury was established. EGF and NT were added to the cells 1 h ahead of carbon tetrachloride given. Twenty-four hours later, cytosolic calcium and membrane fluidity in hepatocytes were detected with fluorescence probe of Fura-2/AM and 1, 6-dihenyl-1, 3, 5-hexatriene (DPH).
  
  
  RESULTS
  EGF and NT could significantly antagonize the increase of cytosolic Ca(2+) and decrease of membrane fluidity in carbon tetrachloride-injured hepatocytes.
  
  
  CONCLUSIONS
  EGF and NT have a function of maintaining membrane fluidity and steady-status of cytosolic calcium of hepatocytes.
