  • Lipoblastoma is a rare benign tumor that usually originates in children from the embryonic lipid cells of the extremities. This condition shows an early childhood occurrence, a benign nature without metastasis, a cellular composition of mainly mature lipid cells and an ability to differentiate into a simple lipoma. We have experienced a 15 month old girl who had developed a lipoblastoma in the right anterior mediastinum. Surgical resection was carried out without complications. Her postoperative course was uneventful. She has been well 6 months after the operation.

  • Lipid contents and fatty acid compositions of 16 kind sea algaes in the southern sea coast of Korea were analyzed to evaluate nutrient significance of total polyene, n-3 polyenes and n-6 polyene fatty acids. Total lipid contents were 0.58 ∼ 3.00% in 9 kinds of brown algaes, 0.47 ∼ 2.16% in 5 kinds of red algaes and 0.55 ∼2..99% in 2 kinds of green algeas. N-3 polyenes and n-6 polyenes of the fatty acid compositions were 1.46∼25.67% and 0∼48.51% in the brown algaes, 1.17∼21.91% and 0.28 ∼29.35% in the red algaes, and 3.67%∼ 10.61% and 4.10 ∼ 8.66% in the green algaes, respectirely. The fatty acid contents and compositions of n-3 polyenes and n-6 polyenes, monoenes and saturates were vary different in the algae groups and sepecies.

  • Multiple symmetric lipomatosis is a rare disease characterized by progressive growth of subcutaneous fat masses which are located symmetrically at neck, shoulders, chest, abdomen and groin. Recent surveys revealed a high incidence of combined somatic and autonomic neuropathy. The exact cause of the disease is not known. We have experienced one case of multiple symmetric lipomatosis with mediastinal involvement with symptomatic compression of trachea. The patient was a 55-year-male, complaining of dyspnea and slowly enlarging multiple symmetric masses at the neck, shoulders, chest, abdomen, flank and groin over a period of 10 years. He had a habit of excessive alcohol intake for many years. The fatty masses in the neck and the upper mediastinum including peritracheal region were excised through transverse cervical incision. But, because of the incomplete excision of peritracheal fatty tissue, we performed reoperation for the relief of residual tracheal compression at the 15th postoperative day. Two days later emergent tracheostomy was performed due to postoperative pneumomediastinum and subcutaneous emphysema. He could discharge with permanant tracheostomy.

  • To search for myrmecochorous plant species, related ant species and diaspore selecting behaviour, collecting fruits and diaspores of four Corydalis species, cafeteria experiments, and the related ant species were studied from May 2013 to July 2014. Four Corydalis species recording in Korea were proved myrmecochorous (seed attached elaiosome) plants newly. Elaiosome shape of these species is spatulate-shaped, but their size is varied considerably in length and width. Significant differences is proved between four plant species in weight of diaspores, seeds and elaiosomes, and elaiosome ratios. Mean values of diaspores weight showed 4.08 mg, 2.56 mg, 2.49 mg and 2.06 mg in Corydalis grandicalyx, C. remota, C. turtschaninovii for. pectinata and C. turtschaninovii var. linearis, respectively. Mean values of seed weights showed 3.68 mg, 2.03 mg, 1.90 mg and 1.67 mg in Corydalis grandicalyx, C. remota, C. turtschaninovii for. pectinata and C. turtschaninovii var. linearis, respectively. Elaiosome ratio of C. turtschaninovii var. linearis was the highest, followed by C. remota, C. turtschaninovii for. pectinata and C. grandicalyx. Ant's preference for the diaspores is ordered as same as elaiosome ratio's order. Major ant species transporting the diaspores of Corydalis species are Formica japonica, Lasius alienus, Lasius japonicus and Tetramorium tsushimae. Formica japonica transports the diaspores most frequently. Ant's preference for the diaspores among plant species or individuals might be influenced on the survival rates of concerned species. Further studies on the myrmecochorous plant and related ant species, cafeteria experiments should be needed.

  • Candida속 효모 27종이 표준 균주를 대상으로 세포내 지방산 조성을 기체 크로마토그래피로 분석하여, 함유 지방산의 종류와 함량비를 근거로 27종이 균주를 3개의 분류군으로 나누었다. 이들 지방산 분석에 의한 분류군을 Candida속의 다른 분류학적 결과들인 coenzyme Q 분자종의 종류, DNA 염기함량 분석, ITS 부위의 제한효소 절단 다형질의 양상, 리보좀 소단위 RNA 유전자의 염기배열 보고와 비교 분석하였다. 그 결과 같은 분류군에 위치하는 균주들 사이의 연관 관계가 거의 일치하였다. 다라서 세포내 지방산 분석은 Candida속 규준들을 유전적 동질성을 갖는 균주들로 분류하는 수단으로 사용될 수 있으며, 유전적으로 매우 다양한 균주들의 집단으로 알려진 Candida속에 관한 분류적 고찰에 일차적으로 사용될 수 있는 유용한 수단임을 알 수 있었다.

  • Mediastinal lipoblastoma is a rare benign tumor originating from embryonic lipid cells and it almost always occurs during infanthood or early childhood. It is a tumor with a good prognosis despite its potential for local invasion and rapid growth. We report here on a three years old girl who was treated for a benign lipoblastoma in the anterior mediastinum. CT scanning showed a fat containing mass without internal calcification or fluid component, and the mass showed a compressive effect on the adjacent structures. The mass was located between the pericardium and right mediastinal pleura and it was removed completely without complication. Pathologic examination revealed a benign lipoblastoma. The patient showed no evidence of recurrence at the time of the report.

  • Purpose: Hibernoma is a very rare benign soft tissue tumor of the hypervascularized brown fat tissue with no malignant potential. Materials and Methods: However, it is difficult to differentiate a hibernoma from other malignant tumors, such as liposarcoma using computed tomography and magnetic resonance imaging, and a surgical resection with histological confirmation is the treatment of choice. Results: Histopathologically, hibernoma is composed of brown adipose cells that are polygonal and multivacuolated with a centrally located nucleus and granular cytoplasm, unlike white adipose cells. Conclusion: This article describes a patient with a histologically-confirmed hibernoma of the right shoulder.

  • Parosteal lipoma is a rare benign tumor containing mature adipose tissue having an intimate relationship to the periosteum. Characteristically, this tumor presents as a lipomatous mass adjacent to bone, eliciting variable reactive changes in the underlying cortex. We report a case of parosteal lipoma of the foot. The MR findings consisted of juxtacortical lipomatous mass abutting to bony protuberance, with internal fibrous striations, and osseous reaction in the adjacent bone. By the aid of multiplanar imaging capability, high spatial and contrast resolution of MRI, characteristic features of parosteal lipoma can lead to diagnosis on imaging.
