The degeneration of intervertebral disc (IVD) is a major cause of low back pain. However, there is no satisfactory preventive treatment for degenerative disc disease (DDD). In this study, we examined the effects of a novel cross-linked hyaluronate hydrogel and cross-linked chondroitin sulfate (CS) hydrogel on a rabbit model of IVD injury. We injected 300(More)
For peripheral nerve regeneration, three-dimensional distribution and growth of cells within the porous scaffold are of clinical significance. We demonstrate that cultured rat Schwann cells and neurospheres grow in vitro on new artificial nerve conduits made with photocrosslinked hyaluronic acid (HA). HA tubular conduits have an inner diameter of 1.2 mm(More)
PURPOSE We investigated the possibility of applying cross-linked hyaluronate hydrogel (HA gel) during trabeculectomy in rabbit eyes. SUBJECTS AND METHODS 1. We injected 0.9% salt solution (n = 3), Opegan-HI (n = 3), or HA gel (n = 3) into the subconjunctiva to make a follicle, and investigated its size. 2. After making a limbal-based conjunctival flap and(More)
The n-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), found in fish oil, exert a number of beneficial effects, and they are used in the treatment of hyperlipidemia. In recent years, EPA and DHA have been found to affect cancer cell proliferation. In the present study, PC3 cells, which are androgen-independent prostate cancer cells(More)
