Abstract: The present invention relates to a pharmaceutical composition for preventing or treating rheumatoid arthritis, and a stem cell therapeutic agent for treating rheumatoid arthritis, comprising nasal inferior turbinate-derived mesenchymal stem cells as an active ingredient. Nasal inferior turbinate-derived mesenchymal stem cells of the present invention have the effects of reducing the production of interleukin-17A (IL-17A), tumor necrosis factor-α (TNF-α), immunoglobulin G2 (IgG2a) which is an inflammation-inducing factor, and/or the proliferative ability of lymph node T cells, increasing interleukin-10 (IL-10) and/or regulatory T-cells (Treg, CD4+CD25+foxp3+ cell) that contribute to immune tolerance in spleen cells, and inhibiting the proliferation of human T-cells. The nasal inferior turbinate-derived mesenchymal stem cells have a safer acquisition process than existing mesenchymal stem cells and can be acquired in sufficient amounts within a desired period of time, thus allowing mesenchymal stem cells to be acquired at low cost and high efficiency. Moreover, since the nasal inferior turbinate-derived mesenchymal stem cells have the same genetic origin as individuals administered therewith there are few side effects, the nasal inferior turbinate-derived mesenchymal stem cells can be usefully used for preventing or treating in individually tailored immunocompatible rheumatoid arthritis.

Abstract: A method for producing a bis(fluorosulfonyl)imide lithium salt is disclosed. The method includes the steps of: (a) reacting bis(chlorosulfonyl)imide with NH4F(HF)n (n=0-10) to prepare ammonium bis(fluorosulfonyl)imide; and (b) reacting the ammonium bis(fluorosulfonyl)imide with a lithium base, wherein in at least one of steps (a) and (b), after the reaction, a process of adding an alkoxy trialkyl silane to the reaction solution to remove a fluorine anion is performed.

Abstract: The present invention relates to a cell therapy composition for preventing or treating immune disease comprising mesenchymal stem cells and immunoregulatory T-cells as an active ingredient. By infusing mesenchymal stem cells and immunoregulatory T-cells, which are the cellular therapeutic agent of the present invention, into bone marrow transplant animals, rejection to the host is suppressed after the engraftment of the transplanted bone-marrow to thus obtain the effect of reducing graft-versus-host disease and immune disease. Moreover, the effect of such GVHD reduction is much greater than the one obtained when only mesenchymal stem cells are infused. Accordingly, the cell therapy composition of the present invention having the above-mentioned effects can be useful in the prevention or treatment of immune disease.

Abstract: The present invention relates to a method for culturing limbal tissues on an amniotic membrane slide scaffold, thereby enabling the proportion of limbal stem cells in a limbal tissue-derived epithelial cell sheet to be effectively increased, and the same to be cultured. According to the present invention, the proportion of limbal stem cells in in a limbal tissue-derived epithelial cell sheet can be stably and rapidly increased, and thus the success rate can be increased when in limbal tissue-derived epithelial cell sheets are transplanted into a patient with limbal stem cell deficiency.

Abstract: The present invention relates to a composition comprising a probe for detecting six representative causative viruses of acute enteritis (norovirus genogroup I and genogroup II, rotavirus, hepatitis A virus, coxsackievirus, astrovirus, and adenovirus), and a DNA microarray, a kit, and a detection method comprising the composition. The present invention is effective due to high specificity and sensitivity to viruses. In addition, since the causative viruses can simply be detected at low cost compared to conventional detection methods, without expensive diagnosis devices or specialists, the present invention may be effectively used as a method for diagnosing viruses causing acute enteritis.
