In the present study we investigated the effects of 11 kinds of edible seaweeds (6 brown and 5 red algae) which contain characteristic seaweed dietary fibers on the induction of D-GalN (D-galactosamine)-hepatopathy in rats (Exps. 1 and 2). Then, the efficacy of various components prepared from Gelidium sp., which was found to alleviate the hepatopathy in Exps. 1 and 2, was examined (Exp. 3). The rats were fed the diets containing various kinds of seaweeds (Exps. 1 and 2), or several components of Gelidium sp. such as total dietary fiber (TDF), soluble dietary fiber (SDF), insoluble dietary fiber (IDF) and dietary fiber-free components (DFFC) (Exp. 3), for 8 d. The rats in all experiments were injected with D-GalN (800 mg/kg body weight) intraperitoneally at the 7th day to induce liver injury and were sacrificed 24 h after the injection of D-GalN. The serum transaminase activities (ALT and AST) and lactate dehydrogenase (LDH) were determined to evaluate the levels of hepatopathy.
