Biochemical markers in carbon-tetrachloride-and galactosamine-induced acute liver injuries: the effects of dihydroquinoline-type antioxidants.

The pharmacological action and possible therapeutic uses of some recently developed synthetic, non-toxic dihydroquinoline-type antioxidants were studied. The effect of the lipid-soluble 6,6-methylene-bis (2,2,4-trimethyl-1,2-dihydroquinoline) (n = 1, 2 or 3) (MTDQ) on carbon-tetrachloride-induced acute liver injuries was investigated, and that of the water-soluble 6,6-methylene-bis (2,2-dimethyl-4-methansulphonic acid sodium-1,2-dihydroquinoline) (MDS) on galactosamine-induced acute liver injuries in CFLP mice (Lati, Hungary). MTDQ was found suitable for the prevention of acute CCl4-induced liver injuries and MDS for that of acute galactosamine-induced liver injuries. Disappearance or significant diminution of the morphological signs and lesions of lipid degeneration and centro-lobular liver necrosis, decrease of serum GOT activities, and also inflammatory changes induced by galactosamine were observed.
