PURPOSE: This study focused on in vitro cell differentiation and surface characteristics in a magnesium coated titanium surface implanted on using a plasma ion source. MATERIALS AND METHODS: 40 commercially made pure titanium discs were prepared to produce Ti oxide machined surface (M) and Mg-incorporated Ti oxide machined surface (MM). Surface properties were analyzed using a scanning electron microscopy (SEM). On each surface, alkaline phosphatase (ALP) activity, alizarin red S staining for mineralization of MC3T3-E1 cells, and quantitative analysis of osteoblastic gene expression, were evaluated. Actin ring formation assay and gene expression analysis of TRAP and GAPDH performing RT-PCR were performed to characterize osteoclast differentiation on mouse bone marrow-derived macrophages (BMMs). RESULTS: MM showed similar surface morphology and surface roughness with M, but was slightly smoother after ion implantation at the micron scale. M was more hydrophobic than MM. No significant difference between surfaces on ALP activity at 7 and 14 days were observed. Real-time PCR analyses showed similar levels of mRNA expression of the osteoblast phenotype genes; osteopontin (OPN), osteocalcin (OCN), bone sialoprotein (BSP), and collagen 1 (Col 1) in cell grown on MM at 7, 14 and 21 days. Alizarin red S staining at 21 days showed no significant difference. BMMs differentiation increased in M and MM. Actin ring formation assay and gene expression analysis of TRAP showed osteoclast differentiation to be more active on MM. CONCLUSION: Both M and MM have a good effect on osteoblastic cell differentiation, but MM may speed the bone remodeling process by activating on osteoclast differentiation.

The purpose of this paper is to study the effects of anti-inflammatory agents on the blood-aqueous-berrier in experimentally induced uveitis. 10% solution of sodium fluorescein was injection intravenously in the ear vein of rabbits (0.25 ml/kg) and fluorescein curve was drawn after the method of Amsler and Huber. Experimental uveitis was induced by the injection of 0.2 ml of human serwn into the vitreous body. After uveitis had been induced. three kinds of anti-inflammatory agents-Prednisolone, Benzyron and Methotrexate-were Biven oralIy. In control animals in which no uveitis was induced, no changes in fluorescein curve were demonstrated before and after the administrations of drugs. In animals with uveitis, maked increases of the blood-aqueous barrier were noted. When Benoyron and Prednisolone were given to these animals, normaliration of the fluorescein curves were demonstrated. Methotrexate had no effects on the fluorescein curves in uveitis animals, showing no improvements in the permeability of uveal vessela. This ineffectiveness seemed to be due to the resistance of rabbits to methotrexate.
