“…Another commonly used surgical model involved PCA plus hepatic artery ligation. This has been described in rats, rabbits, dogs, and pigs, though not in mice, presumably because it is made more impracticable by their size ( Fick, Schalm & de Vlieger, 1987 ; Bonato et al, 1989 ; Ash et al, 1993 ; Argibay et al, 1996 ). PCA may be done at the same time as arterial ligation or separately.…”
