As the use computed tomographic (CT) scanning spread, the diagnosis of blowout fractures of the medial orbital wall increased. Now, the diagnosis of blowout fracture in the medial wall are not uncommon. Conventionally, the surgery of blowout fractures in medial orbital wall was performed by the various approach with external incision. The conventional method had seveal possible disadvantages, including an external scar, incomplete reduction, increased mobidity rate and general anesthesia. Recently, endoscopic reconstruction of the medial orbital wall has provided good functional and cosmetic results. We performed endoscopic transnasal reduction surgery without external incision in 12 cases of medial blowout fracture under local anesthesia. The fractured bony fragments were removed after the intranasal ethmoidectomy and the entrapped medial rectus was released. And then a sheet of silicone late or uncinate process were placed on the fracture site. For the maintain of the position of fractured wall, Merocel packing or urinary ballon catheter were used in orbital fracture site for 1-3 weeks. There were no specific complications related to this procedure. Result of the surgery in all cases were satisfactory. In this article, we discussed the surgical procedure, the benifit of the transnasal endoscopic approach, the indications for surgery, and possible comlications.

PURPOSE: Bone and cartilage were manufactured by using tissue engineering of mesenchymal stem cell (MSC) which can differentiate into variety of cell types. MATERIAL AND METHOD: MSC was isolated and cultured from the rabbit weighing 500g, and it was seeded into PGA mesh and pre-cultured for 1 week with different TGF- beta 3 treated conditions. It was implanted into nude mice and tissues generated were recovered from 1, 2, 3, 4, 8 ,and 12 weeks respectively. Degree of bone and cartilage formation was analyzed with histology and immunohistochemistry assay. RESULT: Pre-culture condition with TGF- beta 3 treatment showed early start of chondrogenic differentiation, and degree of bone and cartilage formation was promoted as time passed. But both of the cases differentiated into complete bone after 12 weeks. CONCLUSION: The results show that pretreatment of TGF- beta 3 promotes the differentiation process in vivo condition under the in vivo system where MSC differentiate into bone via cartilage formation.

The glucose uptake rate by Fasciola hepatica was a mean value of 9.62 +/- 0.54 micro-mole/hr/g, and total CO(2) production rate by the flukes averaged 24.28 +/- 4.26 micro-mole/hr/g wet wt. The relative specific activity of respiratory CO(2) showed a mean value of 79.89 +/- 1.78 per cent. The rate of CO(2) production derived from medium C(14)-glucose was a mean of 19.55 +/- 3.56 micro-mole/hr/g of we wt. Therefore, the average value of 32.72 +/- 4.8 percent of glucose utilized by the flukes from the medium C(14)-glucose was oxidized to respiratory CO(2). The tissue concentration of glycogen in F. hepatica was a mean of 38.36 +/- 2.91 mg/g or 3.84 +/- 0.29 %/g of wet wt, and the turnover rate of glycogen pool was a mean of 1.6+/-0.22 %/hr or 0.65 +/- 0.13 mg/hr/g. The average value of 37.26 +/- 3.86 per cent of glucose utilized by the fluke from the medium C(4)-glucose was incorporated to the glycogen. These data account for that approximately 70 per cent of the utilized glucose by the flukes participated in furnishing the oxidation into respiratory CO(2) and the synthetic process into glycogen.

OBJECTIVE: The purpose of this study was to compare the skeletal, dental, and soft-tissue treatment effects of nonextraction therapy using the modified C-palatal plate (MCPP) to those of premolar extraction (PE) treatment in adult patients with Class II malocclusion. METHODS: Pretreatment and posttreatment lateral cephalographs of 40 adult patients with Class II malocclusion were retrospectively analyzed. The MCPP group comprised 20 patients treated with total arch distalization of the maxillary arch while the PE group comprised 20 patients treated with four PE. Fifty-eight linear and angular measurements were analyzed to assess the changes before and after treatment. Descriptive statistics, paired t-test, and multivariate analysis of variance were performed to evaluate the treatment effects within and between the two groups. RESULTS: The MCPP group presented 3.4 mm of retraction, 1.0 mm of extrusion, and 7.3° lingual inclination of the maxillary central incisor. In comparison, the PE group displayed greater amount of maxillary central incisor retraction and retroclination, mandibular incisor retraction, and upper lip retraction (5.3 mm, 14.8°, 5.1 mm, and 2.0 mm, respectively; p < 0.001 for all). In addition, the MCPP group showed 4.0 mm of distalization and 1.3 mm of intrusion with 2.9° distal tipping of the maxillary first molars. CONCLUSIONS: These findings suggest the MCPP is an effective distalization appliance in the maxillary arch. The amount of incisor retraction, however, was significantly higher in the PE group. Therefore, four PE may be recommended when greater improvement of incisor position and soft-tissue profile is required.

Purpose: This study aimed to determine the incidence of male breast cancer (MBC) and its survival outcomes in Korea, and to compare these results to those for female breast cancer (FBC). Materials and Methods: We searched the Korea Central Cancer Registry and identified 227,122 breast cancer cases that were diagnosed between 1999 and 2016. Demographic and clinical characteristics and overall survival (OS) rates were estimated according to sex, age, histological type, and cancer stage. Results: The 227,122 patients included 1,094 MBC cases and 226,028 FBC cases. Based on the age-standardized rate, the male: female ratio was 0.0055:1. The most common ages at diagnosis were 60-69 years for MBC and 40-49 years for FBC (p < 0.001). Male patients were less likely than female patients to receive adjuvant radiotherapy (7.5% vs. 21.8%, p < 0.001) or adjuvant chemotherapy (40.1% vs. 55.4%, p < 0.001). The 5-year OS rates after diagnosis were 88.8% for all patients, although it was significantly lower for MBC than for FBC (76.2% vs. 88.9%, p < 0.001). In both groups, older age (≥ 60 years) was associated with shorter survival. The 5-year OS rates for the invasive histological types were 75.8% for men and 89.0% for women. The 5-year OS rates in both groups decreased with increasing cancer stage. Conclusion MBC was diagnosed at older ages than FBC, and male patients were less likely to receive radiotherapy and chemotherapy. The survival outcomes were worse for MBC than for FBC, with even poorer outcomes related to older age, the inflammatory histological types, and advanced stage. It is important that clinicians recognize the differences between FBC and MBC when treating these patients.

BACKGROUND: We evaluated the role and effects of prolotherapy in patients presenting with lower back pain and detected sacral asymlocation, by retrospectively analyzing the results of prolotherapy performed at our institute. METHODS: Twenty-three patients with referred pain in the lower back rather than distinct radiculopathy, were detected to have sacral asymlocation by simple X-ray from May 2004 through July 2005. The patients were treated with prolotherapy and manipulation by the Ongley's method around the lumbosacral junction, iliolumbar ligament, and sacroiliac joint. They were treated for approximately one to two week intervals, and during this period were rechecked by X-ray and evaluated using the visual analogue scale (VAS). RESULTS: A total of 23 patients were included in the study (10 male and 13 female), and the average age was 41 years. The average VAS at the time of visit was 8.5, the average treatment time was 4.7 days, and the average VAS after treatment was 2.1. CONCLUSIONS: Back pain, and associated leg and buttock pain, originate from several causes. In these case analyses, instability around the lumbosacral area and sacral asymlocation might have been important causes of patient back pain and associated buttock and leg pain. We therefore applied prolotherapy as well as manipulation techniques devised by Ongley to these patients, and obtained good results.

Nitric oxide (NO) has been considered as an important mediator in inflammatory phases and in loss of cartilage. In inflammatory arthritis, NO levels are correlated with disease activity and articular cartilage is able to produce large amounts of NO with the appropriate inducing factor such as cytokines. The old animals are shown to have a greater sensitivity to NO than young animals. This study evaluated the basal production of NO in normal and OA-affected chondroyctes from young and old patients and compared the levels of NO formation in response to IL-1beta. The results showed that the basal levels were 7-fold higher in old chondrocytes than those of young cells. However, the IL-1beta induced NO production was seen to decrease with age. Aminoguianidine (AG), a competitive inhibitor of iNOS, inhibited NO formation completely in both chondrocytes from young and old individuals. However, at the same concentration of AG it caused partial inhibition of NO and iNOS formation in chondrocytes from OA-affected individuals. In addition, although the IL-1beta induced NO production was much lesser than that of young chondrocytes, the inhibition of collagen production by IL-1beta was prominent in old chondrocytes and OA-affected chondrocytes. These results suggest that age-related differences in the regulation of NO production and collagen production, which may affect the ageing cells and osteoarthritic changes in some way.
