Nigrostriatal dopaminergic neurons undergo sprouting around the margins of a striatal wound. The mechanism of this periwound sprouting has been unclear. In this study, we have examined the role played by the macrophage and microglial response that follows striatal injury. Macrophages and activated microglia quickly accumulate after injury and reach their(More)
Patients who undergo percutaneous transluminal coronary angioplasty (PTCA) by the femoral approach are usually required to lie flat in bed for 6 to 24 hours, which may result in significant discomfort. This study was performed to evaluate the safety and benefit of a flexible sheath that enables patients to sit at a 60-degree angle while the sheath is in(More)
The rate of iron absorption of Fe2+-succinate orally applied with multivitamins, was measured by means of whole-body counter in 45 subjects. The dosage was 330 mg ferrous succinate (115 mg Fe2+). Absorption was generally 4.5% (5.2 mg) in normal subjects, 8.6% (9.9 mg) in subjects with latent iron deficiency, and 29.6% (34 mg) in subjects with manifest iron(More)
