Abstract:
PURPOSE: A hydrogel containing enzyme is provided to prevent infection and to effectively enable wound healing. CONSTITUTION: A hydrogel of a three-layered structure comprises: a first layer containing biocompatible polymers, polyvalent alcohol, and glucose; a second layer containing the biocompatible polymers, polyvalent alcohol, glucoseoxidase(GOD); and a third layer containing the biocompatible polymers, polyvalent alcohol, and horseradish peroxidase. The first layer contains 1-15 wt% of polyvinyl pyrrolidone and 1-30 wt% of carageenan as a biocompatible polymer, 0.1-10 wt% of glycerin as the polyvalent alcohol, and 0.001-3 wt% of glucose as a substrate. The second layer contains 1-15 wt% of polyvinyl pyrrolidone and 1-30 wt% of carageenan as the biocompatible polymers, 0.1-10 weight of glycerin as the polyvalent alcohol, and 0.01-5 wt% of glucose oxidase as the enzyme.
Abstract:
PURPOSE: A patch agent for the local anesthetic including a cross-linked drug free hydrated gel layer is provided to maintain patch form even in reduction of physical property. CONSTITUTION: A patch agent for the local anesthetic comprises a support layer(1), drug-containing hydrated gel layer(3) and peeling layer(4). The drug free hydrated gel layer(2) attached to the affected part opposite surface of the drug content hydrated gel layer is included. The drug free hydrated gel layer emits 30-70 % of the initial drug to the hydration according to the concentration of the drug contained in the drug content hydrated gel layer without the material property degradation of layer after the affected part attach within 1 hour. The drug content hydrated gel layer is the polyvinyl alcohol material of 5-40 weight%, and skin permeation enhancer of 1-20 weight%.
Abstract:
A biochip for measuring phosphorylation is provided to measure the phosphorylation through a simple process with the minimum amount of a sample using radioisotope compared to a conventional method using an antibody and analyze the sample within short time, thereby being usefully used for analyzing the kinase activity. A biochip is characterized in that a substrate of kinase, which is selected from the group consisting of Aurora kinases, tyrosine kinase, PTK(protein tyrosine kinase), MAPK(MAP kinase), MAPKK(MAP kinase kinase), PKA(protein kinase A), PKC(protein kinase C), ERK(extracellular signal-regulated kinase), CAM KII(calcium/ calmodulin-dependent protein kinase II), MEKK(MAP/ERK kinase kinase), JNK(c-Jun N terminal kinase), SAPK(stress-activated protein kinase), p38K(p38 kinase), phosphatase 2B, cPKC(conventional protein kinase), Serine Kinase IKKbeta, Ab1K(Ab1 kinase), BTK(Bruton tyrosine kinase), CDK(cyclin-dependent kinase), VEGF-RTK(Vascular endothelial growth factor-receptor tyrosine kinase), AKT1 kinase, AKT2 kinase, AKT3-kinase, PK(Pyruvate kinase), and Tumor M2-pyruvate kinase, is integrated onto the surface of a substrate such as glass, plastic, metal and silicone, wherein the surface of a substrate is coated with an active group such as amine, aldehyde, carboxyl and thiol. A method for detecting phosphorylation comprises the steps of: (a) mixing a sample to be tested with [gamma-P^32]ATP; (b) treating the biochip with the mixed sample to be tested to induce phosphorylation; (c) washing the biochip; and (d) sensitizing the biochip to measure the phosphorylation degree.
