(Aphyllophoromycetideae) and Vitamin E Supplementation on Enzyme Activities in the Liver and Plasma of Normal and Chemically Induced Hepatocarcinogenic Rats JF International Journal of Medicinal Mushrooms JO IJM YR 2000 FD 2000-06-01 VO 2 IS 2 OP 7 AB Ganoderma tsugae Murr. and vitamin E (α-tocopherol and γ-tocotrienol) were supplemented, alone and combined, to normal rats and rats chemically induced with cancer using a single injection of diethylnitrosamine followed by 0.2% (w/v) 2-acetylaminofluorene and partial hepatectomy. The rats were treated for 16 weeks before they were killed. The activities of alkaline phosphatase (ALP), γ-glutamyl transpeptidase (γGTP), glutathione S-transferase (GST), and uridyldiphosphate glucuronyltransferase (UDPGT) in plasma and subcellular fractions were determined. Blood glutathione levels were also determined. The activities of γGTP and placental GST were determined histochemically in the liver. The ratio of liver to body weight was significantly increased in the cancer-induced rats compared with normal controls. The ratios were unchanged after G. tsugae and vitamin E supplementation. Blood glutathione levels were significantly higher in the cancer-induced rats than normal controls. Supplementation of G. tsugae and vitamin E lowered blood glutathione levels to normal values. The enzyme activities in the subcellular fractions were higher in the cancer-induced rats than in normal controls. The activities were substantially attenuated upon G. tsugae and vitamin E supplementation. Attenuation of the enzyme-positive foci was also evident upon G. tsugae and vitamin E supplementation in the cancer-induced rats. G. tsugae supplementation that started 3 weeks after cancer induction resulted in a similar effect to G. tsugae supplementation started simultaneously with cancer induction.
