  • Treasures patterns are simplified designs of vessels used in everyday life, which were symbols of luck. Treasures patterns on textiles are largely assorted into four groups: eight auspicious patterns of Buddhism, eight immortal patterns of Taoism, seven treasures patterns of King Chakravarti in the Buddhist Scriptures and normal treasures patterns. Among them normal treasures patterns are most commonly used. Records in the Joseon documents show these patterns as being composed of seven treasures patterns or eight treasures patterns. But observation of the actual relics show that these patterns ranged from four to ten patterns. Korean traditional textiles treasures patterns began to appear in Korea on the relics of the last of Goryeo period. They were used as sub-patterns among main patterns of dynamically rising cloud patterns with five heads. Treasures patterns in the early Joseon period were commonly used as sub-patterns, and cloud and treasures pattern were prime examples of this. In the 16th century, lotus vine pattern, small flower vine pattern, or small flower pattern were often used as main patterns and treasures patterns were regularly used as sub-patterns. The robe of the Great Monk of Seo San was unique, in that both main and sub patterns consisted of the treasures patterns. From the 17th century, treasures patterns began to be used as main patterns. For example, a relic with eight alternatively arranged treasures patterns were found. Though there were still some cases where the patterns were used as sub-patterns, they begin to appear bigger than the previous period and became similar to main patterns in size. In the 18th and 19th centuries, there were various cases where treasures patterns were combined with flowers, fruits, animals, and letter patterns and used as main patterns. And there are many different methods of representing and developing the patterns.

  • Henoch-Sch$\ddot{o}$nlein purpura (HSP) is a leukocytoclastic vasculitis of small vessels with deposition of IgA, commonly resulting in skin, joint, gastrointestinal, and kidney involvement. HSP is an uncommon disorder in adults and accounts for 0.6% to 2% of adult nephropathy. We report a case of HSP with acute renal failure successfully treated with corticosteroid. In this case, the patient presented with vasculitic purpuric rash on lower extremity, arthralgia in the wrist, abdominal pain, hematochezia, oliguria and azotemia. Abdominal CT showed wall thickening of the small and large bowels. Skin biopsy revealed leukocytoclastic vasculitis. Percutaneous renal biopsy showed no crescent formation, but mesangial IgA and $C_3$ deposits were observed by immunofluorescence. The patient was treated with corticosteroid (1mg/kg per day) and hemodialysis. After treatment, renal function improved and purpuric lesion, arthralgia and abdominal pain disappeared. Thus, when adults present with purpuric rash and rapidly progressive glomerulonephritis (RPGN), HSP should be a diagnostic consideration.

  • Endothelial progenitor cells (EPCs) are known to play an important role in the repair of damaged blood vessels. We used an endothelial progenitor cell colony-forming assay (EPC-CFA) to determine whether EPC numbers could be increased in healthy individuals through regular exercise training. The number of functional EPCs obtained from human peripheral blood-derived AC133 stem cells was measured after a 28-day regular exercise training program. The number of total endothelial progenitor cell colony-forming units (EPC-CFU) was significantly increased compared to that in the control group (p=0.02, n=5). In addition, we observed a significant decrease in homocysteine levels followed by an increase in the number of EPC-CFUs (p=0.04, n=5), indicating that the 28-day regular exercise training could increase the number of EPC colonies and decrease homocysteine levels. Moreover, an inverse correlation was observed between small-endothelial progenitor cell colony-forming units (small-EPC-CFUs) and plasma homocysteine levels in healthy men (r=-0.8125, p=0.047). We found that regular exercise training could increase the number of EPC-CFUs and decrease homocysteine levels, thus decreasing the cardiovascular disease risk in men.

  • A 7-year-old castrated male Yorkshire Terrier was presented with a palpable intra-abdominal mass. In radiography, a large radioopaque renal mass and small abdominal mass were found on dorsal area of the abdomen. Grossly, red to brown color mass and a cystic structure (hydronephrosis) were embedded in the right kidney. Histopathologically, the mass had many irregular shaped neovascular channels lined by polygonal or oval shaped endothelial cells. These vessels and neoplastic cells had great invasive tendency to adjacent connective or fat tissues. Small abdominal mass had identical morphologic features as in renal mass. According to immunohistochemistry, the neoplastic cells in renal mass demonstrated strong positive signals for vimentin and CD31, and weak positive for von Willbrand factor. However, there were no positive reactions for cytokeratin. Based on the gross, histopathology and immunohistochemistry, this mass was diagnosed as primary renal hemangiosarcoma in a Yorkshire Terrier dog.

  • Henoch-$Sch\ddot{o}nlein$ Purpura (HSP) is a systemic vasculitis involving small vessels with the deposition of immune complexes containing IgA and C3, which is characterized by associated skin, joint, renal, and gastrointestinal manifestations. Although there were several causes such as autoimmunity, infection, and drugs, it also can be presented as a form of vasculitidies associated with malignancies. We report a case of HSP developed during treatment for non-small cell lung cancer in a 66-year-old man. Multiple purpuric skin lesions occurred in both legs after the first cycle of chemotherapy, which was diagnosed as HSP by clinical and pathologic examinations. Due to the itching sensation, topical steroid was applied and the patient was improved 3 weeks later without a scheduled change in chemotherapy.

  • The present study was conducted to investigate the possible role of the sympathetic nervous system in two-kidney, one clip (2K1C) and deoxycorticosterone acetate (DOCA)-salt hypertension. 2K1C and DOCA- salt hypertension were made in Sprague-Dawley rats. Four weeks after induction of hypertension, systolic blood pressure measured in conscious state was significantly higher in 2K1C $(216{\pm}18\;mmHg)$ and DOCA-salt $(205{\pm}29\;mmHg)$ groups than that in control $(128{\pm}4\;mmHg).$ The third branches (<300 ${\mu}m$ in outer diameter) of the mesenteric artery were isolated and cut into ring segments of $2{\sim}3$ mm in length. Each ring segment was mounted in tissue bath and connected to a force displacement transducer for measurement of isometric tension. The arterial rings were contracted by application of norepinephrine (NE) in a dose-dependent manner. The amplitude of the NE-induced contraction of the vessels was significantly larger in hypertension than in control. The NE-induced contraction was significantly enhanced by neuropeptide Y (NPY) in hypertension. Reciprocally, NPY-elicited vasocontraction was increased by NE in hypertension. These results suggest that the sympathetic nervous system contributes to the development of 2K1C and DOCA-salt hypertension.

  • Among many kinds of introduced free flaps, scapular freeflap is one of the most popularly using modalities in fasciocutaneous defect coverage with minimal donor defect and easier procedure and constant vascular patterns of the donor. Many surgeons who had experience of this flap pointed out deficit of the reliable sensation of the transplanted flap is the main shortcoming of the scapular free flap. If we can subjugate that point, scapular free flap is the most excellent procedure in such a cases as heel pad reconstruction and hand reconstruction which are relatively important to have skin with protective sensation. Author performed anatomical literature review, 10 cadaveric dissections and 12 clinical dissections. In surgical anatomical aspect, the upper six dorsal rami of the thoracic nerves have medial branches which pierce Longissimus thoracis and Multifidus muscle with small cutaneous twigs which pierce Latissimus dorsi and Trapezius muscle. Among that cutaneous twigs, several twigs distribute to the skin of the back from midline to lateral aspect which territory is identical to scapular free flap. We analysed clinical experiences of that sensory bearing scapular free flap surgical anatomy and one year follow-up studies with several results. 1) Two to three cutaneous twigs which pierced from the Trapezius muscle over the scapular free flap region. 2) Each twigs has two to four nerve fascicles with small artery. 3) The nerve distributed to the ordinary scapular free flap and large enough size and pedicle length to neurorrhapy with various recipient site nerves. 4) The inconvenience of this procedure is the vascular pedicle and nerve pedicle have opposite directions, vascular pedicle of that comes from lateral direction from subscapular vessels, but nerve pedicle comes from medial direction from trapezius muscle. Author can found constant cutaneous nerve branches which come from piercing the Trapezius. This nerves are helpful for protective sensation in transplanted scapular free flap. We can't had enough follow-up and evaluation of the nerve function of this procedure, we need continuous research works to application of this procedure. The in conveniences come from directional differences of pedicle can solve with longer harvest neural pedicle and change direction of the neural pedicle.

  • Background Single free flaps are a commonly used reconstructive method for multiple soft tissue defects in digits. We analyzed the flap size, division timing, and degree of necrosis in cases with various types of flap division. Methods We conducted a retrospective review of the medical charts of patients who had undergone single free flap reconstruction for multiple soft tissue defects across their digits from 2011 to 2020. The flap types included were the lateral arm free flap, venous forearm free flap, thenar free flap, hypothenar free flap, anterolateral thigh free flap, medial plantar free flap, and second toe pulp free flap. Flap size, anastomosed vessels, division timing, and occurrence of flap necrosis were retrospectively investigated and then analyzed using the t-test. Results In total, 75 patients were included in the analysis. The success rate of the free flaps was 97.3%. All flaps were successfully divided after at least 17 days, with a mean of 47.17 days (range, 17-243 days) for large flaps and 42.81 days (range, 20-130 days) for the medium and small flaps (P=0.596). The mean area of flap necrosis was 2.38% in the large flaps and 2.58% in the medium and small flaps (P=0.935). Severe necrosis of the divided flap developed in two patients who had undergone flap division at week 6 and week 34. Conclusions In cases where blood flow to the flap has been stable for more than 3 weeks, flap division can be safely attempted regardless of the flap size.

  • In this study, pilot study on the introduction of stationary fishery was performed to solve the problem of fisheries resource reduction. The Fyke net, which is a test fishing net was selected considering the environment, operation and management costs of Ulleungdo, conditions that can be operated by small fishing vessels and personnel. As a result of 11 times survey using Fyke net from April to May 2017, 2,735 individuals and 983.4 kg caught and the dominant species were red seabream, yellowtail, olive flounder, mitra squid, horse mackerel, filefish, etc. In conclusion, if the production of squid, which is one of the major fisheries resources of Ulleungdo, is continuously decreased, it is considered that introduction of small-scale stationary fishery such as Fyke net would be useful as a means replace income of fishermen.
