Effect of propranolol on SEM structure of phenytoin-treated rabbit’s liver. A, Scanning electron micrograph of a liver section of a rabbit in the control group shown normal hepatic cords (HC) and sinusoids (S) (4300X). B, PHY treated group showing distinctly distorted hepatic cords (HC) with sinusoidal (S) dilations. Bleb formations on hepatocyt membrane were also observed (thick arrow) (2000X). C, PHY and PRL treated group showing partial restoration of hepatic architecture. Blebs were almost absent (2000X).
