The biocompatibility of the titanium has been estabilished through various experimental studies such as cell culture toxicity test, pyrogen test, mutagen test and others. In order to confirm biocompatibility after fabrication of titanium and to clarify the difference between the bone reaction after insertion of the lathed titanium rods and the bone reaction after insertion of the finished and polished rods, both rods were implanted into the proximal femur of a rabbit. Histologic reactions in the bone were observed according to the ASTM standards at the intervals of 6 weeks, 12 weeks and 26 weeks after implantation. The result were as follows In 6 weeks after implantation of lathed titanium rods, inflammatory reactions, such as minimal degree infiltration of polymorphonuclear leukocytes and lymphocytes were observed in all cases. This was thought to be caused by surgical trauma. However, inflammatory cell infiltration was not seen after implantation of polished and finished rods in all cases. The cellular infiltration and the histologic reaction of the bone after implantation of lathed group were significantly more pronounced than those after implantation of the finished group. In 12 weekt after implantation of lathed rods, two of four cases revealed a minimal degree of cellular infiliration and histologic reaction seemed to be more pronounced in the lathed group, but they were not significant statistically.

8.Aortic Root Replacement with Homograft in Behcet's Disease: A Case Report.
The Korean Journal of Thoracic and Cardiovascular Surgery 1997;30(1):92-96
The prognosis of Behcet's disease characterized by recurrent orogenital ulcers and ocular and skin lesions depends upon the complications in the central nervous system, the gastrointestinal tract and the vascular system. Cardiac involvement, especially aortic regurgitation, is quite uncommon and hemodynamic instability is usually treated with open heart surgery. But serious postoperative complications had been reported in many cases, which are prosthetic valve detachment, paravalvular leakage, conduction disturbance, and false aneurysm. Many efforts to prevent the complications have been made such as application of cryopreseved homograft. We have described an experience of root replacement with homograft in a 39 year-old male patient for prosthetic valve detachment because of Behcet's aortitis with a review of the literatures regarding treatment, complication, and prognosis.

OBJECTIVES: Obstructive sleep apnea (OSA) syndrome is diagnosed through history, physical examination, imaging studies and polysomnography. Clinical examination of this condition may point to hypertrophic tonsils and crowded oropharynx. The objective of this study is to investigate the usefulness of modified Mallampati grade (MMG) and tonsil grade (TG) in predicting the severity of obstructive sleep apnea. METHODS: MMG and TG were divided into 4 and 5 groups, respectively, according to their severity. Medical records were collected from 94 patients who had received polysomnography and otorhinolaryngologic examination for snoring and sleep apnea at Keimyung University Dongsan Medical Center from March 2002 through April 2004. Patients were divided into two groups according to the apnea-hypopnea index (AHI) : control (n=24), and patients with sleep apnea (n=70). RESULTS: Patients with higher MMG and TG had higher AHI, and MMG and TG proved to have a statistically significant correlation with AHI (p< 0.05) CONCLUSION: MMG and TG were reliable predictors of OSA and helpful parameters in deciding treatment method.
