Abstract: Biodegradable polymer microparticles bearing a steroid drug and a preparation method therefor. In the method, a steroid drug and a biodegradable polyester-based polymer are dissolved in an organic solvent and sprayed into a low-temperature hydrocarbon solution to form frozen microparticles that are then immersed in a low-temperature, aqueous salt solution to deprive the microparticles of the organic solvent, thereby preparing biodegradable polymer microparticles bearing a steroid drug. The steroid drug or steroid sex hormone drug-bearing biodegradable polymer microparticles were found to have excellent biocompatibility, biodegradability, porosity, and mechanical strength and to release the steroid drug or steroid sex hormone drug for a long period of time.

Abstract: Provided herein are a membrane-type artificial scaffold for guided bone regeneration (GBR) and a method for fabricating the same. The membrane-type artificial scaffold according to the present invention comprises: a first layer made of at least one fiber layer arranged in parallel with each other with a first spacing therebetween such that the fiber layer contacts a bone tissue in vivo; and a second layer stacked on the first layer and made of at least one fiber layer arranged parallel to each other with a second spacing therebetween such that the fiber layer contacts a soft tissue in vivo. The first spacing is larger than the second spacing.
