In this study, we investigated the anticancer activity of the fin of Thunnus Thynnus (TT ). TT was extracted with methanol (TTM ), and then further fractionated into four subfractions by using solvent partition method, affording hexane (TTMH ), methanol (TTMM ), butanol (TTMB )and aquous (TTMA )soluble fractions. We determined the cyto-toxicity of these four fractions in four kind of cancer cell lines, such as HepG2, MCF-7, B16-F10 and HT29 by MTT assay. The TTMM showed the strongest cytotoxic effect at the concentration of 150 microgram/mL, displaying 95% on the HepG2 cell lines and 82% on MCF-7 cell line. The morphological changes such as membrane shirinking and blebbing of cells were also observed by TTMM treatment in HT29 cell. In addition, we observed that quinone reductase (QR ) activity was elevated by only TTMM and TTMH treatments in HepG2 cell. QR activity was increased to around 2.0 and 1.8 times in TTMM and TTMH treated HepG2 cell at 100 microgram/mL, respectively, compared to that in control. Although further studies are needed, the present work could suggest that the fin of TT has a potential to be usable as a chemo-preventive agent against cancer.

Celastrus orbiculatus (CO) has been used as a traditional herb medicine to treat fever, chill, joint pain, edema, rheumatoid arthritis and bacterial infection in China and Korea. In this study, we investigated anticarcinogenic effects of Celastrus orbiculatus (CO). CO was extracted with methanol (COM), and then further fractionated into four different types: methanol (COMM), hexane (COMH), butanol (COMB) and aqueous (COMA) partition layers. We determined the cytotoxicity of these four partitions in four kind of cancer cell lines, such as HepG2, MCF-7, HT29 and B16F10 Cells by MTT assay. Among various partition layers of CO, the COMM showed the strongest cytotoxic effects on cancer cell lines we used. We also observed quinone reductase (QR) induced effects in all partition layers of CO on HepG2 cells. The QR induced effects of COMM on HepG2 cells at 80 microgram/mL concentration indicated 3.28 to a control value of 1.0. The COMM showed the highest induction activity of quinone reductase on HepG2 cells among the other partition layers. Although further studies are needed, the present work suggests that CO may be a chemopreventive agent for the treatment of human cells.

The H19 gene, located at human chromosome 11p15.5, is imprinted in most normal human tissues. However, imprinting is often lost in tumors suggesting H19 is a putative tumor suppressor. We analyzed the single nucleotide polymorphisms (SNPs) of a 16 kb region that includes the H19 gene and its imprinting control region (ICR) in the Korean population. To identify SNPs, we directly sequenced this region in 18 Korean subjects. We identified 64 SNPs, of which 7 were in the exons of H19, 2 were in the introns, 14 were in the 3' intergenic region and 41 were in the 5' intergenic region. Of the 64 SNPs, 21 had not previously been reported and thus appear to be unique to the Korean population. The identified SNPs of H19 in the Korean population may eventually be useful as genetic markers associated with various diseases. In this study, 7 of the 64 identified SNPs were at CTCF binding sites in the ICR and may affect regulation of H19 gene imprinting. Thus, several genetic variations of the H19 gene may be important markers in human diseases that involve genomic imprinting, including cancer.

Ocular contrapulsion refers to a syndrome of static ocular deviation and saccadic hypermetria toward the intact side, and saccadic hypometria and impaired smooth pursuit toward the lesion side. It has been reported in patients with lesions in the rostral cerebellum and caudal medullary hemorrhge. We report a 60-year-old man who showed ocular contrapulsion with unilateral upper medial medullary infarction. Ocular contrapulsion may be a sign of medial medullary infarction. In our patient, the climbing fibers may be damaged before crossing the midline in the upper medulla.

Eight cases of chondroblastoma were studied by analyzing the clinical and pathologic findings. The age of eight cases ranged from 17 to 38 years old(median age, 22.7 years old). The tumors developed in the femur (3 cases), patella (2 cases), tibia( 1 case), fibula (1 case), and ulna (1 case). The mean diameter of tumors was 4.0 cm (range, 1.5 to 8.0 cm). Grossly, tumors showed grayish brown solid area with foci of secondary aneurysmal bone cyst. Histologically, the tumor cells were round or polygonal in shape with nuclear groove. And there were chondroid differentiation(7 cases), mitosis(3 cases), calcific deposits(3 cases), secondary aneurysmal bone cyst(4 cases), hemosiderin deposits(4 cases), necrosis(3 cases), vascular invasion(1 caes) and foamy histiocytes and cholesterol cleft(1 cases). All cases showed no metastasis to lymph node and distant organ. Seven cases (87.5 %) were immunoreactive for S-100 protein. None were immunoreactive for cytokeratin.

Congenital lipoid adrenal hyperplasia (CLAH) is a rare autosomal recessive disorder characterized by the marked accumulation of lipids and cholesterol in the adrenal cortex, and the failure of adrenal steroids to synthesise. We report the ultrasound (US), computed tomographic (CT), and magnetic resonance (MR) imaging findings in a four-day- old female neonate with CLAH.

A 61 year-old male patient admitted with the complaint of chest pain. During the evaluation, immature cells were found on the peripheral blood smear. Bone marrow aspiration and biopsy were performed. Diagnosis of acute myelogenous leukemia(FAB classification, M2) was made. In the chromosome study using peripheral blood and bone marrow, 47,XYY karyotype was established. Acute myelogenous leukemia has rarely been diagnosed in patients with 47,XYY karyotype, and the effect of extra Y chromosome on oncogenesis is not clear. More studies are needed to be done to clear up the relation between XYY karyptype and leukemia.

To evaluate the effects on the restoration of proprioception, we compared joint position sense (JPS) after meniscal allograft transplantation. Nine patients who underwent meniscal allograft transplantation between March 2008 and January 2010 were evaluated at preoperation and 6 months post-operation. International Knee Documentation Committee (IKDC) subjective score and Lysholm score were evaluated. The peak torque of the isokinetic flexor and extensor strength test was performed using Biodex system III. Passive JPS was assessed to evaluate proprioceptive function. In the results, IKDC subjective score and Lysholm score were improved (p=0.05). The flexor and extensor power decreased, however there was no statistically significant difference. In the assessment of JPS, there was improvement from 6.56degrees and 4.11degrees to 4.89degrees and 1.89degrees, however, this was not statistically significant. Although, proprioception was improved in JPS at 6 months after meniscus transplantation, it did not show statistic significance. Therefore, future studies using combined methods will be needed to evaluate proprioceptive function after meniscal allograft transplantation.
