title: [Effect of tamoxifen on plasma proteins in diabetes mellitus type 1].
abstract: OBJECTIVE
  Considering that important scientific advances have been obtained through studies based on experimental Diabetes mellitus, and that tamoxifen action in humans remains unknown, the aim of the present work is to follow the modifications promoted by diabetes and tamoxifen in the electrophoretic profile of plasmatic proteins.
  
  
  METHODS
  It was used 27 Wistar female rats (180-250 body weight), randomicaly divided into five groups: C1 (n = 3, received vehicle), C2 (n = 3, no treatment), T (n =5, treated with tamoxifen, 0.3mg/Kg/day), D (n = 8, experimental diabetes by estreptozotocin, 45mg/Kg and DT (n = 8, diabetic treated with tamoxifen). The electrophoresis was accomplished in cellulose acetate. pH 8.6-8.8, TECNOW chamber, and the strains were stained by Ponceau S. The total proteins were determined by the Biuret method (Labtest). Proteinograms were obtained in densitometer BioSystems BTS-235.
  
  
  RESULTS
  Albumin decreased progressively in the groups T, D and DT; a1 fraction increased in groups T and DT; a2 fraction increased in groups T and D, including a synergic effect in group DT; a fraction increased in groups T and D; a fraction increased in groups T, D and DT.
  
  
  CONCLUSIONS
  The results indicate an acute phase resposta, with synergic effect of tamoxifen and diabetes, suggesting a probable hepatic lesion.
