    摘要: The present invention relates to an apparatus and a method for separating single cells, and the apparatus includes: a fluid channel which has an upper panel and a lower panel and has a flow path which is formed between the upper panel and the lower panel and configured to convey a sample including a single cell; a single cell measuring unit which includes first and second electrodes which are provided on the fluid channel so as to be spaced apart from each other at a predetermined interval and apply electrical signals to the sample being conveyed through the flow path of the fluid channel, and a detection electrode which is provided between the first electrode and the second electrode and detects the single cell in the sample being conveyed through the flow path, such that the single cell measuring unit applies the electrical signals to the sample being conveyed through the flow path, detects the electrical signals of the sample to which the electrical signals are applied, and detects whether there is the single cell in the sample; and a single cell separation control device which outputs a single cell separation control signal when the single cell is detected by the detection electrode. Therefore, there is an effect of effectively separating, within a short time, the single cells from the sample including the single cells.

    摘要: Provided is a semi-cylindrical osteotomy device including: a guide portion where a tibia accommodating space in which a tibia is accommodated is formed; a cutter portion moving in the tibia accommodating space and cutting the tibia while moving along an inner circumferential surface of the guide portion; and a driving unit driving the cutter portion. According to the semi-cylindrical osteotomy device, stability of a surgery is increased by inserting the guide portion by approaching a side surface of the tibia to minimize an exposed portion of a bone. Also, a wire saw moves along a slit of the guide portion, and thus a cut bone surface of a semi-cylindrical shape is easily and quickly formed.

    摘要: A pharmaceutical composition for preventing or treating an ocular surface disease is disclosed, wherein the pharmaceutical composition includes, as an active component, collagen type II α1 based peptide GQDGLAGPK isolated from chondrocyte-derived extracellular matrix (CDEM). In an alkaline burn animal mode treated with peptide GQDGLAGPK, the occurrence of corneal opacification is reduced as well as the expression of angiogenic factors (e.g., CD31 and VEGF). In addition, the expression of inflammatory markers (e.g., macrophages, TNFα, ICAM-1, VCAM-1, and MMP-9) is reduced while the expression of inflammation-inducing factor (e,g,, NF-κB) is suppressed. The peptide GQDGLAGPK according to the present invention may be applied to a pharmaceutical composition for preventing or treating an ocular surface disease (e.g., a corneal disease).

    摘要: The present invention relates to a cell model for diseases associated with corneal neovascularization by using Epstein Barr virus (EBV)-infected human corneal epithelial cells (HCECs). Provided are a method for preparing a cell model for diseases associated with corneal neovascularization by using EBV-infected HCECs, the method including: infecting HCECs with EBV; culturing the infected HCECs; and determining whether the cultured HCECs are infected with EBV. In addition, provided is a method for screening diseases associated with corneal neovascularization prepared by the cell model for diseases associated with corneal neovascularization.
