Platelet-derived growth factor(PDGF) is known to accelerate soft tissue fracture and periodontal bone healing, but little information is available for characterizing the healing of articualr cartilage. This study was designed to demonstrate the regeneration potential of pasteurized autogeneous osteochondral graft when PDFG was applied locally in vivo. Eighteen rabbits in two groups were used in the experiment. The free osteochondral fragment(1x1x1 cm) were taken from distal femur. The fragment were pasteurized in 65degrees C for 5 minutes. In experimental group(group II), the fragment were soaked in 0.25 mg/ml of recombinant human PDGF mixed 5 ml normal saline and reimplanted to the resected site, and followed with local administration of 0.25 mg/ml PDGF to knee joint. In control group(group I), the pasteurized fragment were reimplanted in the resected site without any treatments. The histologic characteristics of the transplanted autografts for three rabbits in each group were observed at 3, 5 and 7 weeks postoperatively. The results were as follows; Group II revealed the more favorable regeneration of articular cartilage, less arthritic changes and more mature arrangement of chondrocytes than group I. Even thought the cartilage is avascular and the regeneration capacity of pasteurized cartilage is severely limited, the regeneration of grafted articular cartilage is thought to be accellerated by increased newly formed blood vessels and soft tissues due to the diffusion of PDGF on grafted cartilage, and probably also by differentiation of mesenchymal cells in the initial stage of experiment. The results of this study suggest that local administration of PDGF could be used for the treatment of posttraumatic or degenerative arthritis and various cartilage damages.

A 50 year old woman has lost her vision on the right eye abruptly, after subcutaneous Paraffin injection on-the forehead, for cosmetic correction of skin folds. The cause of blindness seems to be due to central retinal artery occlusion and probably to the thrombosis of ophthalmic vein too. It is likely that occlusion of the artery has develoded by compression of tile vessels from outward, but spastic occlusion of the arteries in hypersensitive reaction could not be ruled out.

Purpose:
Pulmonary sarcomatoid carcinoma (PSC) is a rare aggressive subtype of non–small cell lung cancer (NSCLC) with limited therapeutic strategies. We attempted to elucidate the evolutionary trajectories of PSC using multiregional and longitudinal tumor samples.
Materials and Methods:
A total of 31 patients were enrolled in this study and 11 longitudinal samples were available from them. Using whole exome sequencing data, we analyzed the mutational signatures in both carcinomatous and sarcomatous areas in primary tumors of the 31 patients and longitudinal samples obtained from 11 patients. Furthermore, digital droplet polymerase chain reaction (ddPCR), and programmed death-ligand 1 (PD-L1) immunohistochemistry using the Ventana SP263 assay were performed.
Results:
TP53 was identified as the most frequently altered gene in the primary (74%) and metastatic (73%) samples. MET exon 14 skipping mutations, confirmed by ddPCR, and TP53 mutations were mutually exclusive; whereas, MET exon 14 skipping mutations frequently co-occurred with MDM2 amplification. Metastatic tumors showed dissimilar genetic profiles from either primary component. During metastasis, the signatures of APOBEC decreased in metastatic lesions compared with that in primary lesions. PSC showed higher MET and KEAP1 mutations and stronger PD-L1 protein expression compared with that recorded in other NSCLCs.
Conclusion
Decreased APOBEC signatures and subclonal diversity were detected during malignant progression in PSC. Frequent MET mutations and strong PD-L1 expression distinguished PSC from other NSCLCs. The aggressiveness and therapeutic difficulties of PSC were possibly attributable to profound intratumoral and intertumoral genetic diversity. Next-generation sequencing could suggest the appropriate treatment strategy for PSC.

There has been growing concern about the role of sugar-sweetened beverages (SSBs) in the development of obesity. This study investigated factors associated with SSB intake among Korean children (7-12 years) and adolescents (13-18 years). We examined associations between SSB intake and demographic and dietary factors using nationally representative data from the 2008-2011 Korea National Health and Nutrition Examination Survey, and 3,179 children and 2,242 adolescents were included in the final analysis. We calculated adjusted odds ratios (ORs) for factors associated with high SSB intake (> or = 300 ml/day) by multivariable logistic regression. The mean daily SSB intake of school children was 98.7 ml/day, with a mean of 64.7 ml/day for those aged 7-12 years and 120.2 ml/day for those aged 13-18 years. SSB intake of > or = 300 ml/day was found in 12.0% of the children and adolescents. Factors associated with a greater OR for high SSB intake were high energy intake (> or = 125% of EER; OR = 3.17 for boys aged 7-12 years, OR = 2.74 for girls aged 7-12 years, OR = 3.0 for girls aged 13-18 years), low milk consumption (< 1 cup/day; OR = 1.93 for boys aged 7-12 years; OR = 2.53 for girls aged 7-12 years; OR = 1.83 for boys aged 13-18 years), and not meeting the recommended fruit and vegetable intake (< 400 g/day; OR = 1.71 for boys aged 7-12 years). Being overweight and obese was significantly associated with greater ORs for high SSB intake among boys aged 7-12 years (OR = 1.72). These findings may be used to develop targeted education programs for reducing SSB intake and encouraging healthier food choices.

BACKGROUND AND PURPOSE: Different mutations in the Cu/Zn superoxide dismutase 1 (SOD1) gene have been reported in approximately 10% of cases of familial amyotrophic lateral sclerosis (ALS). The aim of this study was to analyze for mutations in the SOD1 gene and clinical characteristics in Korean family of ALS. METHODS: A subpopulation of the family reported here has been described previously. In the present study, we analyzed the SOD1 gene in the proband and his immediate family members, who were not reported on previously. Genomic DNA was isolated from the leukocytes of whole blood samples and the coding region of the SOD1 gene was analyzed by PCR and direct sequencing. RESULTS: The genetic alterations were a GGC-to-GTT transition at codon 10 in exon 1 and [IVS4+15_16insA; IVS4+42delG; IVS4+59_60insT] in intron 4. Patients with these mutations exhibit diverse clinical onset symptoms and acceleration of the age at onset in successive generations, which is called anticipation. CONCLUSIONS: We have described a family with familial ALS that showed autosomal-dominant inheritance and two distinct genetic alterations in Cu/Zn-SOD1. The affected family members had different phenotypes and anticipation.

Mucormycosis is an uncommon, frequently fatal, opportunistic fungal infection. Rhinocerebral and pulmonary involvement are the most common forms and usually occur in immunecompromised patients. Gastrointestinal involvement is extremely rare, the stomach being the most frequently involved site among them. When gastric mucormycosis presents as an invasive fungal infection the prognosis is extremely poor. Alternatively when the fungus may colonize the gastric mucosa without invasion of the blood vessels, the prognosis is good. Early diagnosis and tirnely institution of aggressive treatment is essential for the patients with mucormycosis. We report a 72-year-old man of gastric mucormycosis confirmed by histologic examination of endoscopic biopsy specimen. The patient was admitted. to intensive care unit under the diagnosis of adult respiratory distress syndrome and sepsis. He has been suffered from 5 years of end stage renal disease and 4 months of pulmonary tuberculosis and managed by continuous ambulatory peritoneai dialysis and anti-tubereulosis medications. On the 5th hospital day, esophagogastroduodenoscopy was underwent to remove the pieces of thermometer accidentaly broken, which revealed the 1.0 cm ulcerative lesion on the posterior wall of the upper body of stomach. The base of ulcer was coated with whitish-yellow dirty exudates and slightly irregular and the margin was nodular. The mucosae were friable and easily bled with light touch. The histologic examination of biopsy specimen revealed the multiple non-septated fungal hyphae branching right-angle.
