[Use of immunohistochemical analysis of antigen expression and exfoliative cytology of biliary epithelial cells in diagnosis of mechanical jaundice].

Imaging biliary strictures may suggest malignancy, but cytology can provide final diagnosis. In the present evaluation we studied the importance of immunohistochemical analysis of antigen expression in sensitivity and specificity of cytological evaluation of bile duct epithelium cells. Thirty three patients with biliary strictures were examined prospectively.

[Preoperative autotransfusion and hemodilution and its value in reconstructive vascular surgery].

Autotransfusion and haemodilution are the most safe and well known methods of blood protection in patients planned for vascular operations. During reconstructive vascular surgery autotransfusion with hypovolemic or normovolemic haemodilution were used. In the I group of patients hypovolemic haemodilution was done.
