title: Hypertrophy of the rat Golgi complex during enhancement of cholesterol and bile acids synthesis.
abstract: There are some evidences that the Golgi apparatus could be involved in bile salts transport. In this study we investigate the morphology of the Golgi apparatus in rats with a chronic bile fistula or treated with 4% cholestyramine, a bile salts chelating agent. In both models liver histology was normal by light microscopy. With electron microscopy--compared to sham groups--the only obvious change was the enlargement of the Golgi complex. Morphometric data confirmed that the Golgi rich area volume density was almost doubled after chronic bile fistula or cholestyramine treatment. These data give another support for the participation of the Golgi complex in bile salts transport.
