Abstract:
The present invention relates to a surgical instrument for an iliac vein surgery includes a pressurizing part for fixing an iliac vein, an inclined part inclinedly formed on the end of one side of the pressurizing part, a height control part, for controlling the height, formed on the end of the opposite side to the one side of the pressurizing part, and a handle part formed on the end of the height control part. The present invention has the effects of minimizing interference of a surgical instrument and the hands of an operator at the time of anastomosis during iliac vein surgery, and accordingly reducing operation time and costs.

Abstract:
The present invention relates to a collimator for flow pixel proton therapy, comprising an irradiation region for controlling the intensity of protons to be irradiated by directing shapes of various spaces, wherein a plurality of micro-motors arranged at both sides and a plurality of spread panels arranged in the center are connected to each other, one to one, by an elastic reel, relatively far micro-motors and spread panels are connected to each other by a ratio of the same number, and the plurality of spread panels arranged in the center, which are divided in half and moved to both sides by the opposite micro-motors, are allowed, by the micro-motors, to be in a stress release state of being unwound by the elastic reel. A method for manufacturing a damper and a compensator for proton therapy, which have been conventionally manufactured by hand, is provided to use reverse collimation through a collimator, thereby collimating spread panels at a section requiring spread at the Bragg peak, determining the shape of the section and a damping section through a program, and applying the same to tumor treatment.
Abstract:
The present invention relates to a radiation treatment collimator having a multilayered linkage structure, the collimator providing various shapes of spaces and configuring a radiation area, which transmits radioactive rays, the collimator including: a fixed frame disposed on a plate; multiple pixel board layers fixedly stacked at predetermined intervals on top of each other inside the fixed frame, each pixel board layer being configured in a lattice form and having pixel covers disposed correspondingly to the respective lattices in such a manner as to be open and closed individually; control units disposed on both sides of the fixed frame to individually control the operations of the pixel covers of the pixel board layers; and power source units disposed on the front and rear sides of the fixed frame to supply the pixel board layers with operating power. The collimator is inexpensive and exhibits good treatment results; each pixel can be open/closed separately to form a radioactive ray radiation area; and the collimator is capable of, in real time, converting the shape of the radiation area and adjusting the intensity of the radioactive rays.
Abstract:
Provided is a method for preventing or treating hepatitis C by administrating a composition including, as an active ingredient, a Vitidis Vinferae Radix extract or a fraction thereof and, more specifically, to a Vitidis Vinferae Radix extract which is extracted with water and alcohol or a mixed solvent thereof, or a fraction thereof, which have remarkably low hepatotoxicity and exhibit an excellent effect of selectively inhibiting genome replication of a hepatitis C virus, and thus can be useful for preventing or treating hepatitis C.
Abstract:
Provided is an automatic detection kit for automatically detecting HLA alleles using a real-time polymerase chain reaction (PCR). The real-time PCR is performed on DNA isolated from a sample using a primer which is able to specifically bind to HLA alleles and a fluorescent probe which is able to detect amplification of the HLA alleles in real time, and the HLA allele typing is performed by analyzing a fluorescence value obtained from the real-time PCR using an HLA automatic typing.
Abstract:
The invention relates to a stereovision optometry apparatus comprising: a 3D display unit for displaying 3D image; a reference 2D display unit for displaying reference 2D image; an eyepiece in opposite side of the 2D display unit configured to view the images; a reflective minor in opposite side of the 3D display unit configured to move toward and away from the 3D display unit; and a half minor arranged between the 3D display and the reflective mirror and disposed at a point where propagation paths of the 2D image and the 3D image intersect; wherein the 2D image penetrates through the half mirror to reach the eyepiece; wherein the 3D image penetrates the half mirror to be reflected on the reflective mirror and then the reflected image is reflected on the half mirror to reach the eyepiece.
Abstract:
The invention relates to a composition for angiogenesis inhibition comprising a peroxidasin inhibitor as an effective ingredient, and more particularly, to a method of screening angiogenesis inhibitor, which includes steps of treating a test agent, and analyzing peroxidasin gene expression or protein activity, and comparing peroxidasin gene expression or protein activity between a case treated with the test agent and a case not treated with the test agent. Accordingly, since the inhibitor of the peroxidasin expression or protein activity according to the present invention can effectively inhibit migration, proliferation and tube formation of endothelial cells, the inhibitor can be effectively used for preventing or treating a variety of diseases or conditions of the diseases derived from abnormal regulation of angiogenesis.
Abstract:
Provided are a method for fabricating a human nasal turbinate-derived mesenchymal stem cell-based 3D bioprinted construct, and a use thereof, wherein the human nasal turbinate-derived mesenchymal stem cell-based, 3D bioprinted construct is advantageous over conventional mesenchymal stem cell-based, 3D bioprinted constructs in that the former can survive and proliferate stably in vitro and/or in vivo and shows high osteogenic differentiation ability as well, therefore is expected to make a great contribution to the practical use of cellular therapeutic agents.
Abstract:
A method for treating a cerebrovascular disease according to an embodiment of the present disclosure includes administering a composition comprising at least one of melittin and magnetic iron oxide nanoparticle loaded with melittin as an effective component to a subject in need thereof. A composition according to an embodiment of the present disclosure for preventing, ameliorating, or treating a cerebrovascular disease includes melittin or magnetic iron oxide nanoparticle loaded with melittin as an effective component. The melittin or magnetic iron oxide nanoparticle loaded with melittin not only can reduce the diameter of cerebral arteries, increase the thickness of cerebral arteries, increase the content of elastin and smooth muscles, and reduce the content of abnormal collagen but also has an effect of suppressing the expression of the factors which mediate an inflammatory response.
