美国每年约有5万人患肝癌,平均只能存活4-6月。美国Infusaid公司制成一种植入式药液泵,可用来延长肝癌病人的存活期。该泵的形状大小如曲棍球,由软金属管和贮液室两部分组成。药液泵埋植在腹壁陷凹处的皮肤下面,它通过管子稳定地将抗癌药液输入动脉,随血液进入肝脏。大部分药液能迅速地为肝脏所吸收,而不损伤人体的其它器官。使用这种泵,药物在肝脏里的浓度要比用口服或静脉注射法高400倍,这就大大提高了杀伤癌细胞的效率。药物引起的副作用如脱发和(口恶)心亦大为降低。它还可通过埋
Approximately 50,000 people in the United States suffer from liver cancer each year, with an average of only 4 to 6 months of survival. Infusaid company made a kind of implantable liquid pump, can be used to extend the survival of patients with liver cancer. The shape of the pump, such as hockey, consists of a soft metal tube and a reservoir of two parts. The medicinal fluid pump is embedded beneath the skin of the abdominal wall in a recess. It pumps the anticancer liquid through the tube into the artery and enters the liver with the blood. Most of the liquid can quickly be absorbed by the liver, without damaging the body’s other organs. Using this pump, the concentration of the drug in the liver is 400 times higher than that of oral or intravenous injection, which greatly increases the efficiency of killing the cancer cells. Drug-induced side effects such as alopecia and (bad heart) are also greatly reduced. It can also be buried
