For many years, healing membranous bone fractures have been known to show a persistent lucency at the fracture interface. Radiographic follow-up has proven to be of little value as a guideline for healing of mandibular fractures. Recently, a fracture has been treated by rigid internal fixation by metallic plate and screws rather than closed reduction and wire fixation, we expected that some difference in the radiographic features of fracture healing. To investigate these questions we undertook a retrospective radiographic and clinical analysis of 33 followed patients with fractures of the body and angle of the mandible from 1993 to 1997. There were 26 male and 7 female patients ranging in age between 5 and 74 years, with an average of 29.7 years. All patients were managed by open reduction with metallic plates and screws. The length of follow-up ranged from 9 to 187 weeks. Total 81 radiographic follow-up films were obtained and divided into 3 grades according to the degree of radiolucency of fracture lines; grade 0 radiolucent fracture line and no evidence of fracture interface calcification, grade 1 decreased radiolucent area and evidence of fracture interface calcification, and grade 2 disappearance of fracture line.Until follow-up of 8 weeks, all of the radiographs showed grade 0. From 8 weeks to 16 weeks, 62.5 percent showed grade 0 and 37.5 percent showed grade 1. From 16 weeks to 48 weeks, 38.5 percent showed grade 1 and 61.5 percent showed grade 2. After follow-up of 48 weeks, all showed grade 2.In this study we have shown that the radiographic disappearance of mandibular fracture lines was usually accomplished by 48 weeks. We feel that radiographic union of the mandible is lagging well behind clinical union, but disapperance of the fracture line in rigidly fixated mandibular fracture was occurred earlier than healed by fibrous union. We propose that radiographic union of the mandible by approximately 1 year can be a guideline for the normal mandibular bone healing.

PURPOSE: To determine the efficacy of CarnitilR (acetylcarnitine, Hanmi, Korea) therapy in idiopathic oligoasthenospermic men. MATERIALS AND METHODS: Forty-four subfertile men with abnormal semen parameters were treated between March, 2003 and March, 2004 with 3 g of CarnitilR daily for 3 months. Changes in semen parameters were evaluated 3 months after this therapy. RESULTS: The mean age was 34.2 years and the mean follow-up duration was 3.7 months. In asthenospemic patients (n=28), semen analysis before and after CarnitilR treatment showed an increase in volume (2.64+/-1.65 ml vs. 3.10+/-1.60 ml), motility (35.1+/-17.7% vs. 45.9+/-20.4%) and viability (51.4+/-20.3% vs. 59.3+/-13.6%) respectively. In oligoasthenospermic patients (n=16), semen analysis before and after CarnitilR treatment showed an increase in sperm count (10.7+/-54.4 million/ml vs. 38.4+/-32.5 million/ml) respectively. CONCLUSIONS: These results suggested that in idiopathic oligoasthenospermic men the empirical medical therapy with acetylcarnitine may be considered as primary treatment.

Under specific circumstances the appendix vermiformis may be an appropriate organ for replacement of a large ureteral defect or efferent loop in continent urinary diversion. Since 1995 we have applied the appendix in ureteral substitution (3 cases) and continent urinary diversion (3 cases). Primary diagnoses included complete lower ureteral stricture due to urinary tuberculosis (3 cases), invasive bladder tumor (1 case), areflexic neurogenic bladder (1 case), and contracted bladder (1 case). In all patients who have been replaced the ureter with appendix, clinical symptoms were markedly improved and degree of hydronephrosis decreased. Other patients with continent urinary diversion using appendix achieved dryness and low postoperative complications. we anticipate that the appendix will be used more commonly in the future as a ureteral substitute or continent urinary diversion as more urologists become more comfortable with it through its use in various reconstructive procedures.

Wegener's granulomatosis is a disease of unknown etiology that is characterized by the clinicopathologic complex of necrotixing granulomatous vasculitis of the upper and lower respiratory tract, glomerulonephritis, and variable degrees of small vessel vasculitis. Recently Antineutrophil Cytoplasmic Antibody (ANCA) has been reported to be a highly specific test for the diagnosis of Wegener's granulomatosis. We have experienced a patient of Wegener's granulomatosis in a 11 year old girl who was admitted with complaints f arthralgia, hematuria, convulsion and associated with otitis media and sinusitis. Serologic test of C-ANCA was positive and histologic findings of the kidney showed crescentic glomerulonephritis with sclerosis and surrounding infiltration of multinucleated giant cells. Patient was treated with pulse methylprednisolone without improvement. The clinical course progressed rapidly and expired due to the renal failure, gastrointestinal bleeding and status epilepticus. A brief review of literatures was made.

Journal of Bacteriology and Virology 2015;45(3):256-261
The Bombyx mori decapentaplegic gene is one of the conserved genes in vertebrate and invertebrates. The TGF-beta superfamily contains conserved polypeptide growth factors that play important roles in different cellular processes such as proliferation, apoptosis, differentiation and cell-fate determination. The B. mori dpp gene shares genetic homology with hBMPs and Drosophila dpp. Until now, only few studies have been conducted to examine the functions of B. mori dpp; and hence, its function is not yet well understood. In this study, the baculovirus expression vector system (BEVS) was used for expression of the recombinant B. mori dpp protein and in which the recombinant baculovirus is recovered in the host Sf9 cells. The selected pure recombinant baculovirus containing B. mori dpp gene (rBV-egfp-Bm dpp) was used to increase the effective protein purification by using His-tag extraction strategy. After selection of recombinant baculovirus, recombinant B. mori dpp proteins were extracted from the re-infected cells with pure rBV-egfp-Bm dpp. Herein, we summarize the efficient expression and purification of B. mori dpp proteins from the insect cells using the BEVS. This recombinant protein could be suitable for functional test and various application studies.

OBJECTIVE: Our purpose was to investigate the relationship between the levels of IL-6 and tumor necrosis factor-alpha in the peritoneal fluid(PF) of women with and without endometriosis and infertile women. Design: Prospective and case-control study. Setting: University hospital. Patients: Twenty-nine women with laparotomy or laparoscopic findings of minimal to severe endometriosis, and twenty-eight women with no visual evidence of pelvic endometriosis and with benign gynecologic disease. Main Outcome Measures: PF IL-6 and tumor necrosis factor-alpha levels were determined using commercial ELISA. IL-6 and tumor necrosis factor-alpha concentrations were compared among women with and without endometriosis, and with infertile and fertile women, and then also compared according the revised American Fertility Society classification. RESULTS: IL-6 and tumor necrosis factor-alpha concentrations were higher than in the PF of women with endometriosis than in matched normal controls. Cyclic variations in IL-6 concentrations were seen in PF from patients with endometriosis: the concentrations in the secretory phase were significantly higher than those in the proliferative phase. IL-6 concentrations were higher than in the PF among of infertile women than in fertile women. A significant correlation between PF IL-6 and tumor necrosis factor-alpha concentrations and endometriosis stage III and IV was noted. CONCLUSIONS: Increased PF levels of IL-6 and tumor necrosis factor-alpha in patients with endometriosis may be relate to endometriosis-associated infertility and to the pathogenesis of endometriosis suggesting that partially contribute to the disturbed immune regulation observed in patients with endometriosis.

PURPOSE: To examine the effects of atropine therapy on myopic progression in myopic children. METHODS: Fifty myopic patients, aged from 7 to 14 years and less than -5 diopters, visited our clinic for correction of refractive error from August 2001, and were followed up for at least 1 year. Of these 50 patients, the atropine therapy group was 23 and the control group was 27. Right eye cycloplegic refraction and axial length changes of the two groups were compared and analyzed. RESULTS: There was a mean increase of myopia of 0.25+/-0.43 D/yr in the atropine therapy group and of 0.83+/-0.37 D/yr in the control group (P=0.000). There was a mean increase of axial length of 0.12+/-0.19 mm/yr in the atropine therapy group and 0.39+/-0.21 mm/yr in the control group (P=0.000). In refraction and axial length changes according to age, there was no statistically significant difference within the group, aged from 7 to 9 years. However, there was a statistically significant difference within the group, aged from 10 to 14 years. In refraction and axial length changes according to myopic grade, there were a statistically significant differences between the groups. CONCLUSIONS: Atropine therapy is effective in slowing the myopic progression in myopic children with refractive error less than -5 diopters.
