摘要:
A sustained release sheet that includes a drug for treating nerve injury, wherein the sheet is applied to a nerve injury site, can maintain a high concentration of the drug over a long period, and promotes nerve regeneration without stimulating the nerves, even when the sheet is implanted in the periphery of the nerve injury site. Also provided is a production method for the sheet. This sustained drug release sheet for treating nerve injury is a sheet including a non-woven fabric that is formed from nanofibers each containing a drug such as vitamin B12 and a biocompatible polymer such as a biodegradable aliphatic polyester, and is implanted in the periphery of the nerve injury site to promote nerve regeneration.

摘要:
A Schwann cell differentiation promoting agent, a peripheral nerve regeneration promoting agent, or the like contain an extract from inflamed tissues inoculated with vaccinia virus. The extract from inflamed tissues inoculated with vaccinia virus promotes differentiation of Schwann cells and regeneration of a peripheral nerve. Therefore, a preparation containing the extract from inflamed tissues inoculated with vaccinia virus is useful as a Schwann cell differentiation promoting agent, a peripheral nerve regeneration promoting agent, or the like.
摘要:
A method of treating a central nervous system disease, the method including administering an agent including a therapeutically effective amount of vitamin B12 to a patient with a central nervous system disease to treat the central nervous system disease. This disclosure also relates to a method of promoting M2 macrophage/microglia induction, inhibiting M1 macrophage/microglia induction, and/or reducing the ratio of M1 macrophage/microglia to M2 macrophage/microglia in a patient in need thereof, the method including administering an agent including a therapeutically effective amount of vitamin B12 to the patient to promote M2 macrophage/microglia induction, inhibit M1 macrophage/microglia induction, and/or reduce the ratio of M1 macrophage/microglia to M2 macrophage/microglia. This disclosure also relates to a pharmaceutical product including vitamin B12.
摘要:
The object of the present invention is to provide a test method using a novel administration method of an extract from inflamed tissues inoculated with vaccinia virus or a preparation containing the extract. It has been demonstrated that by sustainedly administering an extract from inflamed tissues inoculated with vaccinia virus or a preparation containing the extract by using a continuous administration device according to the present invention, a comparable effect is exerted at a very low dose compared with conventional administration methods such as oral administration. Therefore, the present invention can provide a test method using animals requiring less burden on a researcher, a treatment of patient at a low dose, and the like.
摘要:
A resistance switching device having a high resistance variation ratio, an excellent response characteristic, an excellent resistance memory characteristic (retention characteristics) and an excellent repeat resistance. The resistance switching device comprises an n-type oxide semiconductor and first and second electrodes which are disposed so as to interpose at least a part of the n-type oxide semiconductor therebetween wherein a Schottky junction which provides resistance variation/memory characteristics by the application of voltage having different polarities between the first and second electrodes is formed at an interface between the n-type oxide semiconductor and the first electrode; and the first electrode is positioned such that it is in contact with the n-type oxide semiconductor, and has a lower layer which is formed from Au oxide or a Pt oxide or Au or Pt containing oxygen having the thickness of 1-50 nm.
