한국산 육생민달팽이유(Limaxpouus와 상ciluria hhstoferi)의 체강벽을 배측부, 복측부 및 외투천 등 3부분으로 나누어 관찰하였으며, 그 결과는 다음과 같다. 1, Limaxpouus의 배측부 체강벽은 많은 모지상돌기 형 태의 근조직과 체강벽상피세포로 구성되어 있으나, 복측부 체강조은 많은 수의 중성점액질 형성세포와 근섬유들로만 형성되었다. 2. Incilaria hhstoferi의 배측부와 복측부는 공히 중성점액질 형성세포와 근섬유들로만 형성되고, 체강상피세포는 관찰되지 않았다. 3. Incilorlo jruhstor$\ulcorner$sri의 병투막측 체준벽은 불규칙한 모양의 단층 체강상피세포와 많은 근섬유로 구성되었다.

Intramuscular lipid of longissimus dorsi muscle(white muscle), soleus muscle(red muscle) and cardiac muscle were autooxidized at $37^{\circ}C$ for 20 days, and the rancidity development and the effect of various factors on rancidity development were compared. Although the myoglobin content of red muscle was about 5 times as high as that of white muscle, the degree of autooxidation occurred in intramuscular lipid did not differ between red muscle and white muscle, when they had the same lipid content. Accordingly, it was suggested that the susceptibility of muscle tissues to lipid oxidation depends mainly on the lipid content of muscle tissue, regardless of muscle types. Lipid oxidation was not a major quality deterioration for dried-pork product, when it contained adequate amount of sodium nitrite and was air-tight vacuum-packed.

Inflammatory myofibroblastoma is a solid tumor, occurring mainly to children and young adults, and occupying 0.7% of total isolated pulmonary nodules. Since 1973, several cases about inflammatory myofibroblastoma have been reported. Firstly, this tumor was found in lungs. Then, tumors have been founded and reported in mesentery or cardioesophageal region. Histologically, this tumor can be classified as a benign tumor. However, since this tumor has two characteristics showing malignancy, that is, local invasion and recurrence, malignancy can not be completely excluded. Recently, a patient with pulmonary inflammatory myofibroblastoma underwent surgical resection without any signs or symptoms of recurrence.

This study is to characterize the effects of swimming exercise on the composition of muscle fibers in rats lower limb tissue. By comparing the exercised group (4, 8 weeks) with the control group, we analyzed the difference histologically, histochemically and morphometrically. The obtained results are as follows ; 1. In the histological view, the distance between the individual muscle fibers and the muscle bundles in exercised group was shorter than that of control group. The irregular shape of sarcolemma in exercised group was observed. 2, In the histochemical view(NADH-TR. and Myosin ATPase reaction analysis), the increased populations of red and intermediate fibers were observed, whereas the white fiber was decreased. 3. In the morphometrical view, the red and intermediate fibers of tibialis anterior and gastrocnemius in exercised group were quantitatively increased, compared with control group. However, the white fiber and connective tissue in exercised group were decreased.

Inflammatory myofbroblastic tumor in the lung is a rare tumor. The etiology is not clear. This tumor in children is a benign tumor rarely presented with local invasiveness, recurrence, distant metastasis or malignant changes can occur. The complete surgical resection is chosen as the optimal management. A 12-years-old boy visited the outpatient clinic with a 4 cm sized pulmonary mass in left upper lung field. The patient underwent left upper lobectomy. Histopathologically, inflammatory myofibroblastic tumor was confirmed. The patient was discharged without any problems and there was no evidence of recurrence during 3 months follow-up.

Inflammatory myofibroblastic tumors (IMTs) are rare. They are characterized by myofibroblastic spindle cell proliferation with a varying degree of inflammatory cell infiltration. IMT can occur in any anatomic location but has been reported in the lung, mesentery, and omentum, mainly in children or young adults. It rarely occurs in the pancreas and is often difficult to distinguish from other tumors, including some malignant ones. Therefore, it can be challenging to make a radiological diagnosis of IMT. Here, we present a case of IMT that occurred in the pancreas head of a middle-aged female. The patient's ultrasonography, computed tomography, and magnetic resonance imaging findings are presented along with a review of the literature.

Purpose: We analyzed the oncologic characteristics and outcome of patients with inflammatory myofibroblastic tumor of extremities. Materials and Methods: Among the soft tissue tumor patients who were treated between 1999 and 2012, 5 patients who were pathologically confirmed as the inflammatory myofibroblastic tumor of extremities were analyzed retrospectively. Results: There were 1 man and 4 women with mean age of 44 years (37-55 years). The average follow up was 34.6 months (8-87 months). All patients underwent surgical treatment. Only 1 patient had wide resection margin and remaining 4 had marginal (3) or intralesional (1) resection margin. All of 4 patients without wide resection margin developed local recurrence at 10.3 months (8-19 months). Malignant transformation to fibrosarcoma was occurred in 2 patients who developed local recurrence, and 1 patient developed multiple metastases to lung, liver and lymph nodes and expired at 37 months. Three of 5 patients had tumor location abutted to or invasion to major arteries and 1 patient had tumor invading sciatic nerve. Conclusion: It is observed that inflammatory myofibroblastic tumor of extremities is usually located near the major neurovascular structure. Wide resection should be considered as the initial surgical treatment because this tumor showed a high local recurrence rate and possibility of malignant transformation.

This study examined the histochemical and physiological characteristics during Korean native Ogol chickens (KNOC) development. The body weight, Pectoralis major and soleus muscle weights, and muscle samples were taken at hatching as well as at 3, 5, and 15 weeks of age. The fiber characteristics of the Pectoralis major and soleus muscles from the KNOC at hatching to 15 weeks of age were determined, and the deoxyribonucleic acid (DNA), ribonucleic acid (RNA), and protein concentrations were measured from the left Pectoralis major muscles. A greater increase in body and muscle weights was detected between hatching and 3 weeks of age than during any other period. Moreover, the cross sectional area (CSA) of the fibers, as well as the total concentration of DNA, RNA, and protein also showed a greater increase betweenhatching and 3 weeks of age than during any other period. The KNOC breed is a dual purpose breed, however, the it has lower body and muscle weights than commercial meat type chickens or layer type chickens. Moreover, the KNOC breed has a small muscle fiber CSA of and a low nucleic acid concentration.

우육으로부터 제조된 수리미유사물의 낮은 pH는 가열된 수리미유사물의 젤 강도를 강하고 단단하게 하는 것과 관련이 있는 것으로 나타났다. 계육과 돈육은 근섬유가 더 굵고 직경이 큰 것으로 나타났고, 가열된 수리미유사물내 무정형 단백질의 부분적인 입자가 더 크게 형성하고 있는 것으로 나타났다. 가열된 수리미유사물의 젤 형성력과 조직감은 근원섬유단백질내 마이오신의 비율에 영향을 받는 것으로 나타났다. 마이오신의 비율은 우육으로부터 제조된 수리미유사물에서 가장 낮게 나타났고, 그 결과 수리미의 단단한 조직감과 젤 내 작은 덩어리가 많은 것으로 나타났다.

Octopus variabilis의 흡반을 광학현미경과 주사전자현미경 그리고 투과전자현미경을 이용하여 그 미세구조를 관찰하였기에 이에 보고하는 바이다. 또한 내측상피 부위 돌기구 조물 속에서 관찰된 세포들은 핵을 둘러싼 세포들이 공포화 현상으로 인하여 해면처럼 보였다. 이 세포들은 감각과 수축에 관여하는 해면질성인 세포로 생각된다. 외측 상피조직에서는 2종의 분비성인 감각세포(A 및 B형세포)차 2종의 상피성인 감각세포(C 및 D형세포)가 관찰되었다. 분비성인 감각세포는 감각이외에 점액분비 기능을 소지하였으며, 상피성인 감각세포는 상피의 지지와 감각기능을 수행하는 것으로 생각되었다. 흠반을 구성하고 있는 근섬유는 중앙이 기린 도나스 형태로서 10-15개의 종선이 나타났다. 또한 부위에 따라서는 근섬유들은 서로 집결하여 원주형의 근육 기등을 형성하기도 했는데 이들은 신경섬유에 의하여 서로 연결 되고 통제되었다.
