A study of  ̄(99m)Tc- EC in mice and its preliminary clinical application[J]. Nuclear techniques, 1994, (5).
研究显示了99mTc-EC的化学量对小鼠肾放射量浓聚有很大的影响,只有当鼠接受1.25mg/kg剂量时肾的放射量最高.肾/肝达3.2。它的小鼠毒性和与血浆蛋白的结合率均低.14例健康志愿者肾显像表明99mTc-EC是一种有用的锝标记肾功能显像剂.
Mouse experiment revealed that the concentration of 99mTc-EC in kidney was highly dependent on the chemical amount of the injected tracer.A highest concentration in kideney was found at a dose of 1.25 mg per kg of body weight
with a kidney/liver ration as high as 3.2.Its toxicity was low and only a small percentage was bound to plasma protein. Preliminary study on 14 healthy volunteers suggests that 99mTc- EC is a hopeful functional imaging agent for kidney.
