The purpose of present study was to observe the radiographic finding and histologic response by Confocal Laser Scanning Microscopy(CLSM) on interface of the bone and titanium implant coated by chitosan. The tissue of rabbit tibiae to the surgical placement titanium implant coated by chitosan was examined at 3, 9 and 24 days postoperatively. The radiographic finding showed that surrounding bone density of implants was not significantly different compare with the bone on 3 and 9 days group. A large amount new bone was formed on 24 days group, the reason was osteconduction activity by chitosan. The CLSM analysis show that the surface coating by chitosan filled the gap between bone and implant on 3 days group and filled by mew born on 9 days group. On 24 days group, the bone and titanium surface was filled by lamella bone. This results indicated that this enhanced the initial stability of implant significantly and chitosan induced osseointegration around implant. CLSM allows the non-destrutive histo-tomography of bone biopsy as well as clinical practice. We conclude that CLSM allowed a good comprehension of the nature of bone-implant contact, avoiding artifacts due to the thickness of the specimen.

PURPOSE: Caveolin-1 is proposed to represent a novel tumor suppressor protein and expression of recombinant caveolin-1 is sufficient to restrict the growth potential of transformed cells isolated from primary tumors of the breast, lung, and ovaries. We examined the relationship of caveolin-1 and Ki-67 expression to clinicopathological variables in patients with clear cell carcinomas of the kidney. MATERIALS AND METHODS: We examined caveolin-1 and Ki-67 expression in 119 clear cell carcinomas of the kidney using immunohistochemistry, and analyzed its relationship with tumor size, nuclear grade, TNM stage, vascular invasion, capsular invasion, metastasis, and metachronous metastasis were investigated. RESULTS: Of the 119 tumors analyzed, lymph node and distant metastasis (synchronous metastasis: 7, metachronous metastasis: 15) occurred in 3 and 22 cases, respectively. Caveolin-1 expression correlated with the T stage(p=0.004), TNM stage(p=0.013), metastasis(p=0.013), and metachronous metastasis(p=0.001). Ki-67 expression correlated with the T stage(p=0.041), nuclear grade(p=0.011), and vascular invasion(p=0.043). Caveolin-1 and Ki-67 expression showed similar changes, but there was no statistical significance(p=0.050). CONCLUSIONS: Caveolin-1 is expressed frequently in patients with metachronous metastasis, and may predict metastasis after surgery for clear cell carcinoma of the kidney.

PURPOSE: To experimentally investigate the effect for muscle weakness after superior rectus Z-myotomy and histological changes. METHODS: Superior rectus muscle fibers of rabbits (16 rabbits, 32 eyes) were cut transversely with scissors across 75% of the muscle in two different positions on opposite sides. In group 1 (16 eyes), myotomies were performed at 2 and 7 mm from the muscle insertion (5 mm gap) and in group 2, performed at 2 and 5 mm (3 mm gap). The change of mark, eyeball position, and muscle tension after myotomy and 4 weeks postoperatively was evaluated, the location of the mark was examined, and muscle tissue biopsy was performed. RESULTS: After Z-myotomy, the marks of the two groups moved significantly posteriorly from insertion within groups (p<0.05), with no significant differences between groups (p=0.469). Eyeball positions of the two groups moved significantly inferiorly (p<0.05); the amount of position change of group 1 was greater than group 2 (p<0.05). When the globe was pulled in opposite directions for muscle action, the degree of change decreased with significant difference within groups (p<0.05), but there were no significant differences between groups (p=0.32). CONCLUSIONS: Z-myotomy of the superior rectus muscle affected the recession of eyeball position and weakened the muscle action. Muscle weakening affected by the different gaps between myotomies did not show consistent results.

BACKGROUND/AIMS: Fibromyalgia (FM) is a common rheumatologic disease characterized by chronic widespread pain, along with various clinical manifestations including atypical autoimmune characteristics. Despite its high prevalence, there remain no approved laboratory tests to identify specific manifestations of FM, or to rule out FM from other rheumatic diseases. Anti-dense fine speckled 70 (anti-DFS70) antibodies were initially identified as a form of anti-nuclear antibodies in a patient with interstitial cystitis. Anti-DFS70 antibodies are found in ≤ 10% of healthy individuals, but have suggestive negative association with autoimmune diseases; however, the clinical significance of these autoantibodies in FM patients remains poorly understood. METHODS: We examined 39 patients with FM, along with 17 patients with systemic lupus erythematosus (SLE), and 19 healthy individuals (HI). Patients were compared based on physical measurements, disease duration, tender point counts, FM Impact Questionnaire (FIQ) scores, visual analog scale (VAS) for pain, somatic symptoms, and anti-DFS70 antibodies. RESULTS: Levels of anti-DFS70 antibodies were significantly higher in the FM and HI groups than in those with SLE. Both anti-DFS70 antibodies and VAS scores were positively correlated with FM. Within the FM group, patients with arthralgia had higher anti-DFS70 antibody values compared to those without arthralgia (p = 0.024); antibody levels were also higher in patients with sleep disturbances relative to those without sleep issues (p = 0.024). In contrast, there were no correlations between anti-DFS70 antibodies and age, body mass index, disease duration, tender point counts, FIQ, short-form health survey results, or other clinical manifestations. CONCLUSIONS Anti-DFS70 antibodies may represent a useful biomarker for differentiating between FM and other autoimmune diseases. The levels of anti-DFS70 antibodies were also significantly higher among patients with arthralgia and sleep disturbances. Further investigations are necessary to evaluate the relationships between anti-DFS70 antibodies and other cytokines as a predictive marker for pain.

Acute thyroid abscess is an uneommon type of neck infection. We experieneed a case of staphylococcal thyroid abscess in 29 year old man, diagnosed by needle aspira~tion and culture of the aspirate. The patient had complained fever and slowly growing anterior neck swelling. Needle aspiration of the cold nodule prior to broad spectrum antibiotics was performed. After Surgical excision combined with antibiotics, he was discharged with elinical improvement. The laboratory diagnosis and clinical course was summarized and is reported with relevent references.
