Portal and Hepatic Vein Embolization versus Portal Venous Embolization Alone in Cirrhotic and Noncirrhotic Swine: A Pilot Study.

Purpose: To evaluate the effectiveness of combined portal vein embolization (PVE) and hepatic vein embolization (HVE) compared with that of PVE alone in cirrhotic and noncirrhotic swine.

Materials And Methods: Sixteen Yorkshire pigs were included in this study. In the cirrhotic group (n = 8) and noncirrhotic group (n = 8), subjects underwent embolization according to established protocols.

Mucoadhesive plasticized system of branched poly(lactic-co-glycolic acid) with aciclovir.

Commercially available antibacterial semisolid preparations intended for topical application provide only short-term drug release. A sustained kinetics is possible by exploitation of a biodegradable polymer carrier. The purpose of this work is to formulate a mucoadhesive system with aciclovir (ACV) based on a solid molecular dispersion of this drug in poly(lactic-co-glycolic acid) branched on tripenterythritol (PLGA/T).
