쥐 간세포를collagenase perfusion method에 의해 분리한 뒤 collagen coated dish와floating collagen membrane에서 일차배양하여 간세포의 분화기능을 조사하였다. 두 경우 모두 간세포의 생존율은 5일 이후부터 점차 감소하였거나 간세포에 의한 암모니아 처리기능과 albumin생성기능은 약 7일간 유지되었다. 또 이러한 분화기능에 유지는 ollagen coated dish보다floating collagen membrane이 유리한 것으로 나타났다. -

Aluminum (Al) accumulation increases with aging, and long-term exposure to Al is regarded as a risk factor for Alzheimer’s disease. In this study, we investigated the effects of Al and/or D-galactose on neural stem cells, proliferating cells, differentiating neuroblasts, and mature neurons in the hippocampal dentate gyrus. AlCl3 (40 mg/kg/day) was intraperitoneally administered to C57BL/6J mice for 4 weeks. In addition, vehicle (physiological saline) or D-galactose (100 mg/kg) was...
