  2. Abstract

  3. 雌鼠 • all → 死亡率↑ 2~3倍 • 雄鼠 • Only 3groups →All results were hormone and sex dependent, and the pathological profiles were comparable

  4. Introduction • 政府 • 沒有要求長期動物餵食研究 • 產業界 • 90天老鼠餵食試驗的研究 →2年期的詳盡的老鼠餵食研究

  5. Materials • 玉米品種 • 抗草甘膦轉基因玉米NK603 • 接近的同基因非轉基因作物 • 草甘膦除草劑農達

  6. Methods

  7. Result – Mortality

  8. Result-Anatomopathologicalobservations

  9. 雄鼠肝臟 雄鼠腎臟 雌鼠乳腺 雌鼠垂體

  10. 草甘膦除草劑農達最低劑量的影響 對照組肝實質細胞 轉基因玉米22%

  11. Result - Biochemical analyses • ferulicacid • 減少了16-30% • caffeic acid • 21–53%

  12. Discussion 90天餵食試驗的不足 ↓ 長期研究評估測量

  13. THANKYOU
