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 lower ureter is not so frequent site of the urinary tract obstruction. In lower ureteral obstruction, the obstruction should be relieved by any method for maintaining renal parenchyme. A clinical studies were made on the 24 ureters of the lower ureteral obstruction. This studies were mainly focused on the method of management by internal stent indwelling. The following results were obtained. 1. In etiology, acquired lower ureteral strictures were most common ; tuberculosis in 10 ureters, radiation in 6 ureters, pelvic lymphadenopathy in 4 ureters, and iatrogenic stricture in 3 ureters. Congenital UVJ stricture was only one ureter. 2. In the method of management, open surgeries were done in 10 ureters and endourologic methods in 14 ureters. 3. In 5 failures of the first management, open surgeries were done in 3 ureters and endourologic methods in 2ureters. The tuberculosis was the most of their etiology. 4. Complications in internal stent indwelled cases were flank pain, severe vesical irritation, migration into the bladder and the obstruction of the lumen of stent.
