The present study is intended to observe the chronologic changes of experimental sparganosis by histopathological observation and detection of circulating anti-sparganum IgG antibody using ELISA. Each of 25 mice was infected with aye spargana, and they were examined after 1, 2, 4, 10 weeks or 6 months from infection. The followings are summarized results. - 1. The plerocercoids were detected in the subcutaneous tissue of the trunk, neck or axilla, but a few often extended into the skeletal muscle. The recovery rates were 72% at the first week, 80% at the second week, 95% at the fourth week, 92% at the tenth week and 100% at .the sixth month. The larvae grew slowly in both length and weight until 6 months. 2. Histopathologically, most of the larvae were observed alive in the soft tissue or skeletal muscle. Numerous eosinophils, neutrophils, Iymphocytes and plasma cells were infiltrated focally around the worms by the second week, but they surrounded the worms to form a layer of inflammatory reaction after 4 weeks of infection. Also histiocytes and fibroblasts began to appear around the inflammatory cells at 4 weeks. After 10 weeks, the worms encircled by a thin fibrous layer were found. After 6 months, the worms were surrounded by either fibrous tissue or active inflammatory cells. The inflammation looked more severe in the tracks left by the worms, rather than around the worms. 3, The level of anti-sparganum IgG antibody in the serum showed an increase by the fourth week, and a rapid and continuous increase was observed thereafter by the tenth week after infection. The high level of the IgG antibody was maintained up to 6 months forming a plateau curve. The present results suggest that the tissue reaction and antibody production in subcutaneous sparganosis become distinctive by the fourth week after infection.

A 1-year-old female hedgehog was presented with subcutaneous mass in the right forelimb. Grossly, an elevated subcutaneous mass approximately 4 cm in diameter was located in forelimb. Central dark brown area was surrounded by peripheral milky white zone in the cut surface of mass. Histopathologically, numerous neoplastic cells formed irregular cords or sheets in dermis. Most of neoplastic cells showed palisading features to basement membrane with or without central caseous necrosis. These neoplastic cells showed invasive tendency to adjacent tissues. According to immunohistochemistry, the neoplastic cells demonstrated strong positive signals for pancytokeratin, and negative for vimentin. Based on the gross, histopathology and immunohistochemistry, this mass was diagnosed as basal cell carcinoma in a hedgehog.

The development of subcutaneous emphysema is a well-known complication that has been reported after dental extraction, endodontic treatment, or restorative preparation. Gaseous invasion, leading to swelling, crepitus on palpation, is commonly restricted to the connective tisssues immediately adjacent to the entry site. However, the use of compressed air- and water-cooled turbines may allow large amounts of air and water to be driven through the fascial planes into the mediastinum, pleural space, or even the retroperitoneum. This case report is about the patient who presented with subcutaneous emphysema that occurred after fracture line inspection. Possible cause, treatment, and prevention of emphysema will be discussed.

Angiomatoid fibrous histiocytoma is a rare soft tissue tumor that generally affects children and young adults. We report a case of angiomatoid fibrous histiocytoma in an 11-year-old boy who complained of a back mass for 3 years. Surgical excision was performed. The excised specimen showed a $4.0{\times}3.6{\times}3.0cm$, well circumscribed, grayish white tumor, with multicystic changes. Histological examination showed proliferation of spindle or round shaped tumor cells. There was a dense fibrous pseudocapsule with prominent chronic inflammatory cell infiltrates.

This study was carried out to obtain fundamental data on the metabolism of hibernant fish loach, Misgurnus mizolepis. Main focus was on the compositon of muscle components and its changes in fresh - water loach before and after spawning season and before and after hibernation. Distributional changes of carbohydrate, protein and lipid in the muscle tissues were also investigated. Change patterns of miosture and crude protein, and moisture and crude lipid were in inversely proportional, i.e. : moisture amount showed the lowest value after spawnig season, the highest just after hibernation, but crude protein and crude lipid were the highest values after spawning season, and the lowest just after hibernation. Carbohydrate showed the highest value just before hibernation and tended to decrease thereafter. Muco layer of epidermis and muscle cell of hypodermis layer in loach were remarkable in its PAS dyeing degree after sapwning season, and it was presumed to include high percentage of protein or carbohydrate. Dermis layer became thinner before spawning hibernation. Lipid component in female tended to distribute relatively widely in the muscle cell layer before spawning season, but in case of male mainly in muco layer and epidermis layer. It appeared that lipid was spreaded mainly in epidermis and hypodermis tissue after spawning season, while it prevailed in almost all tissues but tended to decrease after hibernation.

A rat is the most common experimental animal used for the realization of the radiation injury model. The certain thickness of rat skin was prepared by peeling off a rat skin. Radiation level was measured by using this rat skin. Also, The schematic of the formula was made that can predict the radiation absorbed dose (RAD) as a function of the thickness of the rat skin. Consequently, we will provide the RAD information in the realization of in-vitro experimental model regarding the rat's skin thickness by applying the formulas. Moreover, the results from this study can be effectively used for the in-vitro experiment of the rat subcutaneous tissue which was exposed to radiation.

피부는 신체를 둘러싸고 있는 하나의 막이다. 이것은 우리의 생명 보존에 절대 불가결한 것이며 그 사람이 살아온 과정과 연륜을 말해주는 것으로 나무의 나이테와 같은 것이라고 할 수 있다. 피부의 총 면적은 개인에 따라 약간씩 차이는 있지만 평균 1.5~2.0㎡ 정도이고 피부의 두께는 평균 2mm이며 피하조직을 제외한 두께는 약 1.4mm정도이다. 신체 부위 중 가장 얇은 곳은 눈꺼풀이며 가장 두터운 곳은 손, 발바닥이다. 인체의 신비를 보여주는 우리 몸의 기관 그 세 번째 피부에 대해서 한림대학교 성심병원 피부과 김철우 교수, 리더스 피부과(강남 압구정점) 박병순 전문의의 도움말로 알아본다.

본 논문에서는 초고주파를 이용하여 하지정맥류(Varicose vein)의 초기증상인 모세혈관 확장증(Telangiectasia)을 치료하는 데에 목적을 두었다. 유전율 차이에 따라 전자파(Electromagnetic waves)를 흡수하는 양이 다르다는 것을 전제하에 다리 모델링에 필요한 피부, 혈관, 혈액, 피하조직의 유전율을 구하였고, 혈관과 피부의 유전율에 비해 혈액의 유전율이 높다는 것을 통해 다른 조직에 비해 혈액의 전자파 흡수율이 높다는 것을 확인하였다. 피부의 구조와 유전율을 이용하여 모델링 한 후, 시뮬레이션을 통해 SAR(Specific Absorption rate)분포를 확인하였다.

Despite the many advantages of magnetic resonance imaging in orthopedic prosthetic body image distortion to the differences in the magnetic susceptibility occurs. Attached to the phantom and pork produced by the same $65{\times}15{\times}2mm$ stainless steel and titanium specimen examined the relationship between magnetic resonance imaging and phantom images, the signal intensity changes of the subcutaneous tissue, fat-suppressed quantitative assessment of the degree through the length of image distortion and pig bones. Stainless steel to titanium to 2.8 times 4.4 times in the longitudinal direction than in the direction of the height of large image distortion, signal strength is relatively low 58.5%. Normal 56.2% compared to the subcutaneous tissue, fat-suppressed, were stainless steel 16.04%, 54.53% titanium. Experimental results than the diagnostic value of magnetic resonance imaging (MRI) images of stainless steel with a titanium metal if better could see.
