Rhabdomyosarcoma is the most common soft tissue sarcoma in childhood and acounts for 6% to 15% of all cases of childhood cancer, Rhabdomyosarcoma in seventh most common form of childhood neoplasms, following acute leukemia, tumors of the central nervous system, lymphoma neuroblastoma, Wilm`s tumor, bone tumor. Rhabdomyosarcoma can arise anywhere in the body, but primary site in the thorax is relatively rare. We experienced a case of aveolar rhabdomyosarcoma arising from intercostal muscle, A 12 year-old woman was suffered from the intermittent left chest pain radiating to the scapular area and dyspnea, On physical examination, pulmonary friction rub was heard on the left upper lobe area. Qn adimission, the chest simple radiography revealed a 7 x 6, 5cm sized radio-opaque mass with pleural effusion in the superior mediastinum and the CT showed a well difined radio-opaque mass including the destructed 2nd rib and pleural effusion. The percutaneous tra-nsthoracic needle aspiration biopsy was likely to show blastoma. After the chemotherapy[vincristine, actinomycin-D, cyclophosphamde] was done to treat blastoma, the pleural effussion was subsided and the mass was slightly decreased by 4.5x 4. 5cm. For treatment and diagnosis, we performed en-bloc resection and the defected chest was reconstucted with Gortex patch. Grossly, the specimen was colored graysh-white and arised in between two ribs The microscopic findings showed that the tumor cells were small round with scant pinkish cytoplasm on the H-E stain and the tumor cell nests were grouped by reticulum fibers and showed alveolar pattern on the silver stain The electromicroscopic finding presented that the cytoplasm contained tangled fibrillar and flocculent materials. The histopathologic findings were compatable with laveolar rhabdomyosarcoma. She was discharged without any complication. After discharge, she has been treated with radiation theraphy and chemotheraphy, and not recurred untill last follow-up We report a case of alveolar rhabdomyosarcoma arising to intercostal muscle, developed in 12 year-old waman, with brief review of literatures.

The purpose of this study is to investigate the modulatory effect of emodin on hydrogen peroxide production in human blastoma SH-SY5Y cells induced by the synthetic analog of double-stranded RNA [polyinosinic-polycytidylic acid]. Hydrogen peroxide production was measured by dihydrorhodamine 123 (DHR) assay. Emodin significantly inhibited the polyinosinic-polycytidylic acid (PIC)-induced production of hydrogen peroxide for 0.5, 2, 12, 18, and 24 hr incubation at the concentrations of 5, 10, 25, and 50 uM in SH-SY5Y (P < 0.05) in dose dependent manner. These results suggest that emodin has neuroprotective property related with its inhibition of hydrogen peroxide production in PIC-induced neuronal cells.

Osteoblastoma is an uncommon lesion of bone that occurred in jaw bone. The etiology of the Osteoblastoma is still undiscovered. The most frequent symptom is consistent pain which is often severe, and localized swelling and bone expansion mat occur. We experienced a case of osteo-blastoma which occurred on the lingual surface of mandibular body. It resembled tours mandibularis clinically, alveolar abscess radiologically. Biopsy was done to evaluable the tours-like bony mass. The results of excisional biopsy demonstrated an osteoblastoma. The symptoms are subsided and no signs related with recurrence have been noted. Our experience and many literatures demonstrated that Osteoblastoma must be included in differential diagnosis of bone-producing lesion.

A case of dento-maxillofacial abnormality involving a 10-year-old male patient with a history of esthesioneuro-blastoma is presented. This patient had been treated with 54 Gy /sup 60/Co-gamma-radiation to the nasal cavity for 6 weeks and 6 cycles of combination chemotherapy of Cyclophosphamide, Cisplatin, Adriamycin, VM-26 (Tenipo-side), and DTIC (Dacarbazine) when he was 16 months of age. Five years after cessation of cancer therapy, he was disease free and transferred for extensive dental care to Kyung Hee University Dental Hospital. A clinical and radiologic follow-up over last 4 years showed root stunting, premature closure of the root apices, microdontia, developmental arrest, small crowns, and partial anodontia. Maxillofacial morphology evaluated by cephalometric analysis showed deficiency of maxillary development.

Congenital pulmonary airway malformation (CPAM), previously known as congenital cystic adenomatoid malformation, is a rare developmental lung abnormality associated with rhabdomyosarcoma, pleuropulmonary blastoma, and mucinous adenocarcinoma of the lung. We report an unusual case of a 10-day-old male newborn with a left lower lobe pulmonary cyst who underwent lobectomy, which revealed type II CPAM complicated by multifocal mucinous adenocarcinoma. KRAS sequencing revealed a somatic mutation in Codon12 ($GGT{\rightarrow}GAT$), suggesting the development of a mucinous adenocarcinoma in the background of mucinous metaplasia. Mucinous adenocarcinoma is the most common lung tumor associated with CPAM, but it generally occurs in older children and adults. Further, all cases in the literature are of type I CPAM. This case in a neonate indicates that malignant transformation can occur very early in type II CPAM.

Fucoidan, that is high-molecular-weight sulfated polysaccharides extracted from brown seaweeds has been shown to elicit various biological activities. Here, we investigated the effects of fucoidan on cell proliferation and nitric oxide (NO) production in neuronal blastoma cell (SH-SY5Y). In the present study, we demonstrated that fucoidan treatment resulted in increase of cell proliferation and NO production. When cells were treated with amyloid-${\beta}$ (A${\beta}$) in the absence or presence of fucoidan, fucoidan recovered the cell viability decreased by A${\beta}$ peptides. To further determine whether nitric oxide synthase (NOS) is involved in proliferative effect of fucoidan, cells were treated with NOS inhibitors in the absence or presence of fucoidan. Selective constitutive nitric oxide synthase (cNOS) inhibitor, diphenylene iodonium chloride (DPI), caused a decrease of cell viability, whereas cell viability was increased by specific inducible nitric oxide synthase (iNOS) inhibitor, S-methylisothiourea (SMT), in the fucoidan-untreated cells. Treatment with fucoidan inhibited the cell viability decreased in DPI-exposed cells. In contrast, fucoidan had no effect on cell growth in SMT-treated cells, indicating that cNOS may not play a role in the proliferation of fucoidan-treated cells. The present data suggest that fucoidan has proliferative and neuroprotective effects and these effects may be associated with iNOS.

Fetal adenocarcinoma is a rare adenocarcinoma subtype of pulmonary blastoma. A 48-year-old male patient is being referred to our hospital due to progressive dyspnea. A chest X-ray showed a lung mass of unknown origin that was obstructing the right main bronchus. After relieving the airway obstruction with stent insertion via bronchoscopy, a diagnosis of fetal adenocarcinoma is being confirmed through thoracoscopic biopsy. Due to the locally advanced state of the lung cancer, it seemed to be inoperable, and concurrent chemo-radiation therapy was being administered with docetaxel. The stent was removed after improvements in the airway obstruction followed by a lung mass shrinkage. Comparing to other contexts which describe fetal adenocarcinoma as lower grade malignancy with low-associated mortality, herein, we describe a case of locally-advanced fetal adenocarcinoma (T4N3M0). This is the first documented case being treated with concurrent chemoradiation therapy. The followed-up image studies represent a partial response and the patient is currently under further observations.

Objectives: This study was carried out in order to examine the effects of Gastrodiae rhizoma(GR) ethanol extract on neuronal apoptosis in intracerebral hemorrhage(ICH)-induced rats. Methods: ICH was induced by the stereotaxic intrastriatal injection of bacterial collagenase type VII in Sprague-Dawley rats. GR was orally given once a day for 3 days after ICH. Histological changes of the peri-hematoma regions were observed by cresyl vioIet staining. Bcl-2-associated X protein(Bax), B-cell blastoma 2(BcI-2) and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling(TUNEL) expressions in the affected regions were performed by immunohistochemistry. Results: 1. GR reduced apoptotic bodies and swelling neurons in the peri-hematoma regions of ICH-induced rats. 2. GR significantly reduced TUNEL positive cells in the peri-hematoma regions of ICH-induced rats. 3. GR significantly reduced Bax positive cells in the peri-hematoma regions of ICH-induced rats. 4. GR did not influence Bcl-2 expression in the peri-hematoma regions of ICH-induced rats. Conclusions: These results suggest that GR has neuroprotective effects against ICH-induced apoptosis.
