Polymeric micelles incorporating cisplatin (CDDP) were prepared through the polymer-metal complex formation between CDDP and poly(ethylene glycol)-poly(glutamic acid) block copolymers, and their utility as a tumor-targeted drug delivery system was investigated. CDDP-incorporated micelles (CDDP/m) had a size of 28 nm with remarkably narrow distribution.(More)
Neuropeptide Y (NPY) was continuously administered to Wistar rats in the normal and glioma bearing conditions intracarotidly via the external carotid artery and local cerebral blood flow (LCBF) was measured by a [14C] iodoantipyrine technique. In the normal rats, the LCBF at the injecting side of NPY markedly reduced in 2 minutes after beginning of drug(More)
Neuropeptide Y (NPY) was continuously administered to Wistar rats intracarotidly via the external carotid artery and local cerebral blood flow (LCBF) was measured by a quantitative autoradiography using [14C]iodoantipyrine. A remarkable reduction in LCBF was observed in the NPY infused hemisphere. This depression was irregular and was particularly evident(More)
Since 1984, we have treated 11 malignant glioma patients with intracarotid infusion of ACNU [1-(4-amino-2-methyl-5-pyrimidinyl)-methyl-3-(2-chloroethyl)- 3-nitrosourea hydrochloride] in addition to surgical removal and irradiation. We experienced three patients, who showed clinical manifestation of leukoencephalopathy and computed tomographic (CT) findings(More)
Since the first reports of pituitary oncocytoma by Kovacs and Horvath, and Landolt and Oswald increasing numbers of cases have been reported with the advent of electron microscopy. It has been posturated that more cases were not precisely diagnosed because of lack of electron microscopic study. We reported two cases of pituitary oncocytoma and discussed(More)
