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-&#x3b1; (TNF-&#x3b1;), 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, CD4CD25foxp3cell) 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.

The present invention relates to a polyimide film and a preparation method thereof. According to the present invention, a polyamic acid solution having a high weight-average molecular weight may be obtained by adjusting viscosity and solid content of the polyamic acid solution, and thus, a desired polyimide film may be prepared therefrom. Furthermore, since a length of carbon chains rearranged during graphitization is increased, a graphite sheet having excellent thermal conductivity can be prepared from the polyimide film of the present invention. Also, since the polyimide film has improved windability by further including inorganic particles as a filler, it may facilitate the wind operation.
