Abstract
  1. The effect of tocotrienol and tocopherol on glutathione S-transferase (GST) and gamma-glutamyl transpeptidase (GGT) activities in cultured rat hepatocytes were investigated. 2. Tocotrienol and tocopherol significantly decreased GGT activities at 5 days in culture but tocotrienol also significantly decreased GGT activities at 1-2 days. 3. Tocotrienol and tocopherol treatment significantly decreased GST activities at 3 days compared to the control but tocotrienol also decreased GST activities at 1-3 days. 4. Tocotrienol showed a more pronounced effect at a dosage of greater than 50 microM tocotrienol at 1-3 days in culture compared to the control.
摘要
  1. 研究了生育三烯酚和生育酚对培养的大鼠肝细胞中谷胱甘肽S - 转移酶(GST)和γ-谷氨酰转肽酶(GGT)活性的影响。2. 生育三烯酚和生育酚在培养5天时显著降低了GGT活性,但生育三烯酚在培养1 - 2天时也显著降低了GGT活性。3. 与对照组相比,生育三烯酚和生育酚处理在3天时显著降低了GST活性,但生育三烯酚在1 - 3天时也降低了GST活性。4. 与对照组相比,在培养1 - 3天时,剂量大于50微摩尔的生育三烯酚显示出更显著的效果。
