At the altitude of approximately 250 of Mt. Sori located in Kyung-gi Co, Korea authers have made a field collection of Drosophila during June, 1 and 15, 1961, and found about 30 specimens which seemed to be a new species belonging to Genus Drosophila, Subgenus Hirtodrosophila. AUthors have named the species : D. macromaculata sp. nov. " Its Korean name is given , : Uluck-muni-chopari". This species is very similar to Drosophila cheda in its external feature and especially it that each of four stripes in the mesonotum is cut into tow, and it also resembles with Drosophila calloptera in that it has three distinct spots in the wing. Its first segment of abdomen is yellow-brown in color while both end points are black. The second segment is black and in its middle part there yellow-brownish strips of V form, the peripheral part of which are found two spots of yellow brownish color. On third to fifth segments of male and on third to sixth segments of female there are fod-form spots, one on each segment, and on both sides of these rods two smaller spots are found in each segment. This species is clearly a fungus feeder and its breeding in authers laboratory is at present, not attained. Holotype : male , Kwang-nung, Kyung -gi Do, South Korea, 1 Male June, 1, 1961. Allotype : female, collected together with holotype. Paratype : Kwang-nung, Male 16 and female 12. Distribution : South Korea. Collecting method : Net sweeping on the decayed trees.yed trees.

In the present study we investigated the peripheral function of capsaicin and KR-25018, a newly synthesized capsaicin derivative, which was demonstrated to have a potent analgesic activity through different mechanism from morphine and nonsteroidal antiinflammatory drugs. Capsaicin (10-8~10-5 M) and KR-25018 (10-8~10-5 M) produced concentration-dependent contractions of the isolated guinea pig bronchi. There were no significant differences in the maximum response and the EC50 values (EC50: 0.137$\pm$0.025 $\mu$M and 0.097$\pm$0.031 $\mu$M for capsaicin and KR-25018, respectively, P>0.05). Phosphoramidon (10 $\mu$M) and indomethacin (10 $\mu$M) had no significant effect on contractile response to the submaximal concentration range of capsaicin and KR-25018 (3$\times$10-9~3$\times$10-7 M). The response to KR-25018, like that to capsaicin, was significantly inhibited by ruthenium red with reduction in the maximum response, which is indicative of non-competitive antagonism. A further common feature of the responses to capsaicin and KR-25018 in the guinea pig bronchi was their sensitivity to capsazepine. Capsazepine caused a rightward parallel shift in concentration-response curves obtained by capsaicin and KR-25018. the pA2 values of capsazepine were 5.90 and 5.99 against capsaicin and KR-25018 response, respectively. In conclusion, KR-25018 and capsaicin exert their contractile effects in the isolated guinea pig bronchial muscle by common mechanisms, probably via the activation of a specific receptor.

In this paper, a novel approach is addressed to facilitate the browsing of large collection of digital photos associated with specified person(s) in the photos. The goal of the proposed method is to exploit additional person-identity features as incorporating facial regions and peripheral clothes region associated with them. For more effective incorporation of the clothes and facial features, situation-based photo clustering is also proposed. To evaluate the efficacy of the proposed method experiment was performed with 1120 generic home photos. The experiment results showed that the proposed method outperformed the conventional method us El.g only face feature as showing the average performance of about 92% contrary to the average performance of about 70% in the conventional method.

Eosinophils are known to be important effector cells in pathogenesis of asthma. The elucidation of mechanism by which eosinophil survival is regulated in vivo at sites of inflammation is critical tn our understanding of asthma pathogenesis. The maintenance of these cells at site of inflammation depends upon tile balance between its tendency to undergo apoptosis and tile local eosinophil-viability enhancing activity, Qualitative and quantative phenotypic differences have been observed between bronchoalveolar lavage (BAL) and peripheral blood (PB) eosinophils (EOS). We hypothesize that BAL EOS Possess altered functional feature compared to PB EOS. BAL and PB EOS were obtained from ragweed allergic asthmatics after segmental antigen challenge (SAC) at 24 hour or one week, and purified over percoll and CDl6 negative selection. Cells were cultured in duplicate in RPMI, 15% FCS and 1% penicillin/streptomycin without exogenous cytokines. Eosinophil purity and viability was >92%. BAL. EOS viability was 69${\pm}$4.4% versus 39${\pm}$1.6% for PB EOS (p<0.005) at 48 hour time point, and this difference was maintained through day 5 (32${\pm}$7.6% vs. 3.0${\pm}$ 1.4%, p<0.05), Among BAL EOS, those harvested one week after SAC appeared to have an prolonged survival compared to those harvested at 24 hour. Coculture of BAL and PB EOS resulted in significant viability enhancement than expecteed. Direct neutralization of GM-CSF activity, not IL-3 and EL-5, markedly decreased tile survival of BAL EOS in culture, and abrogated tile viability enhancing activity of their culture supernatants in a dose dependent manner. We conclude that BAL EOS activated in vivo possess enhanced viability compared to PB EOS. Mixing and neutralization experiments suggest a role for autocrine production of GM-CSF.

Background: Behçet disease is a chronic inflammatory disorder with a varying etiology. Herein, we report the involvement of peripheral veins in Behçet disease and discuss the treatment thereof. Methods: Thirty-four patients with venous involvement in vasculo-Behçet disease were retrospectively analyzed over 15 years. We reviewed the clinical manifestations, treatment choices, and complications of these patients. Results: Deep vein thrombosis (DVT) was observed in 24 patients (70.59%) and varicose veins in 19 (52.94%). Immunosuppressive treatment was administered to all patients due to the pathological feature of vein wall inflammation. In patients with DVT, anticoagulation therapy was also used, but post-thrombotic syndrome was observed in all patients along with chronic luminal changes. Eleven patients with isolated varicose veins underwent surgery; although symptoms and lesions recurred in half of these patients, no cases of secondary DVT occurred. Conclusion: When DVT was diagnosed in patients with Behçet disease, there was no cure for the lesions. Ultrasonographic abnormalities were observed in all patients, and post-thrombotic syndrome remained to varying degrees. In cases of isolated varicose veins in patients with Behçet disease, DVT did not occur after surgical treatment. If the activity of Behçet disease is controlled, surgical correction of varicose veins is preferable.

The musculoskeletal system is mainly composed of the bones, muscles, tendons, and ligaments, in addition to nerves and blood vessels. The greatest difficulty in an ultrasonographic freeze-frame created by the examiner is recognition of the targeted structures without indicators, since an elephant's trunk may not be easily distinguished from its leg. It is not difficult to find descriptive ultrasonographic terms used for educational purposes, which help in distinguishing features of these structures either in a normal or abnormal anatomic condition. However, the terms sometimes create confusion when describing common objects, for example, in Western countries, pears have a triangular shape, but in Asia they are round. Skilled experts in musculoskeletal ultrasound have tried to express certain distinguishing features of anatomic landmarks using terms taken from everyday objects which may be reminiscent of that particular feature. This pictorial review introduces known signature patterns of distinguishing features in musculoskeletal ultrasound in a normal or abnormal condition, and may stir the beginners' interest to play a treasure-hunt game among unfamiliar images within a boundless ocean.

The advance of the immunobiology clarifies the nature of non-Hodgkin's lymphoma(NHL). In addition the proceed in the immunophenotyping renders the classification of NHL. According to the Revised European American Lymphoma(REAL) classification, classified by the etiologic factors, molecular biological characteristics, immunophenotype, cytogenetics and histologic feature, nasal T/NK-cell lymphoma(=angiocentric lymphoma) belongs to the category of peripheral T-cell and natural killer cell lymphoma. Nasal T/NK-cell lymphoma is a distinct clinicopathologic entity characterized by progressive necrotic lesions in the nasal cavity, nasopharynx, and palate. The cellular origin of this tumor has been controversial. Although most nasal T/NK-cell lymphomas are of NK-cell lineage, being CD56+, negative for surface CD3(Leu4), and unassociated with rearrangements of the T-cell receptor genes, other minor variants have been reported. This lymphoma is a rare disease and usually experienced in adult. Recently, we experienced a rare type lymphoma, nasal T/NK-cell lymphoma, in 14 years old boy. His soft mass occupied the right nasal cavity including the nasal septum and turbinate. Pathologically this nasal mass showed the infiltration into the vascular wall, illustrating angiodestructive lesion. The cellular origin was NK-cell lineage, being CD56+ and negative to CD3. Now, we report the case with a brief review of related literatures.

Background: The purpose of this study was to investigate the correlation of contrast-enhanced ultrasonographic (CEUS) features with microvessel density (MVD) in papillary thyroid carcinomas (PTCs). Materials and Methods: Contrast-enhanced ultrasonography (CEUS) was performed in 62 patients (17 men and 45 women) with PTC. Tomtec software was applied to analyze the time intensity curve of CEUS. Immunohistochemistry was performed to evaluate the level of MVD in papillary thyroid carcinoma. Then the relationship between quantitative feature and the level of MVD was analyzed using SPSS 16.0 software. Results: The mean peak intensity of PTC tissues was lower than that of peripheral thyroid parenchyma ($61.9{\pm}11.8%$ vs 100%, p<0.05). The MVDs of CD34 and CD31 antibodies staining were $38.0{\pm}6.1$ and $37.9{\pm}5.1$ respectively in 62 PTC samples. A significantly positive correlation was observed between peak intensity and MVD in PTC tissues ($P_{CD34}$<0.01, $r_{CD34}$=0.838, $P_{CD31}$<0.01, $r_{CD31}$=0.837). Conclusions: The peak intensity in CEUS could reflect the MVD in PTC tissues. Therefore, quantification of CEUS seems to be helpful for assessment of MVD in PTC tissues.

Alagille syndrome is a autosomal dominant disorder characterized by intrahepatic bile duct paucity and resultant chronic cholestasis in combination with cardiac(mainly peripheral pulmonary stenosis), skeletal, ocular, and facial abnormalities. In addition to the pulmonary stenosis, in large series, anecdotal reports of vascular lesions have concerned the renal artery, aorta, hepatic artery, carotid artery, celiac artery or subclavian artery. Theses diffuse vascular abnormalities, which appear to be a feature of Alagille syndrome, suggest Notch signaling pathway defects affect angiogenesis. The associations of Alagille syndrome with moyamoya disease, the chronic cerebrovascular occlusive disease, were reported and suggested as additional evidence of vasculopathy of Alagille syndrome. We report another 25 month-old Alagille syndrome girl who presented with acute left hemiparesis and was diagnosed with moyamoya disease through the cerebral angiographic study.
