  • The authors have observed clinically and histopathologically on two cases of rhabdomyosarcomas occurred in the oral cavity. The results were as follow: 1. A case of adult pleomorphic rhabdomyosarcoma, involving the right mandibular third molar area of 52 year old male, revealed pathological fracture of the right mandibular angle area. Microscopically, sections of this tumor showed cross striations by staining of phosphotungstic acid hematoxylin. 2. A case of embryonal alveolar rhabdomyosarcoma, involving the right buccal area of one year and ten months old female, revealed severe bone destruction on the right mandibular body area. Microscopically, sections of this tumor did not show cross striations.

  • We report a rare case of rhabdomyosarcoma spontaneously arising in an anterior mediastinal teratoma in a 47-year-old male. The patient was found to have an anterior mediastinal mass on a chest X-ray, which was taken two months before his presentation to Asan Medical Center. A subsequent computed tomography scan revealed an $8.9{\times}7.1{\times}8.0$ cm heterogeneous mass in the anterior mediastinum. He underwent an excision via median sternotomy. The histopathologic study identified a mature teratoma with embryonal rhabdomyosarcoma.

  • 후두는 호흡기가 시작되는 부위로 후두의 태생학적 연구는 타장기에서와 같이 정상 후두의 해부학적 이해, 후두 기형의 병인의 이해 및 치료에 기초 자료가 된다. 그러나 사람 배아의 후두 발생에 관한 연구는 재료확보가 용이하지 않고 해부학적 난이성으로 매우 드물다. 이에 저자는 사람 배아의 후두 발달을 연구하고자 배령이 확인된 20례의 배아(배령 4 주에서 8 주 까지)의 연속절편에서 광학현미경하에 후두 발달의 형태학적 관찰을 시행하여 다음과 같은 결과를 얻었다. 1. 배령 4 주에 median pharyngeal groove, laryngotracheal sulcus 와 tracheoesophageal septum 이 관찰되었다. 2. 배령 5 주에 hypopharyngeal eminence, epithelial lamina of larynx와 arytenoid swelling이 관찰되었다. 3. 배령 6 주에 hyoid condensation과 tracheoesophagealfistula가 관찰되었다. 4. 배령 7 주에 epiglottis 가 확인되었고 hyoid bone, thyroid lamina 와 cricoid cartilage 의 condensation 및 muscular condensation 이 관찰되었다. 5. 배령 8 주에 laryngeal cartilage의 chondrification과 ventricle이 관찰되었으며, vestibulotracheal canal과 pharyngotracheal canal 의 교통은 관찰되지 않았다.

  • 횡문근육종은 간배세포에서 발생한 비교적 드물고 악성도가 극히 높은 종양이다. 환자는 50세 남성으로 약 2개월간의 사성을 주소로 내원하였다. 검사결과 우측 성대의 전 1/3부위에 0.5 cm$\times$0.3cm크기의 종물을 볼 수 있었다. 전신마취하에서 종물을 절제하였으며 생검결과 배상형의 횡문근육종임 이 확진됐다. 저자들이 알기로는 후두부횡문근육종의 증례는 현재까지 전세계적으로 24례의 보고가 있었다. 후두부에서 발생한 횡문근육종의 1례를 문헌적고찰과 함께 보고하는 바이다.

  • Primary mediastinal immature teratoma is a rare germinal tumor which includes various elements of mature teratoma, choriocarcinoma, yolk sac carcinoma, embryonal carcinoma, and seminoma in some proportions. The tumor is virtually restricted to young man and the response to surgery and radiotherapy are poor. Recently, we experienced a case of primary mediastinal immature teratoma with elevated serum [-HCG and [-fetoprotein in 18 years old man. The well-encapsulated mass, weighing 4.5 kg, was completely resected and then adjuvant combination chemotherapy was tried with Vincristine, Bleomycin, and Cisplatin. Radical excision of tumor and adjuvant chemotherapy would appear to produce better result than have been reported in other cases. The postoperative course was uneventful and the tumor markers were returned to normal range.

  • LBD-005, a newly developed recombinant granulocyte-macrophage colony-stimulating factor, was at dose levels of 0, 20, 80 and 320ng/kg/day administered subcutaneously to pregnat New Zealand White rabbits during the organogenetic period. The dams were subjected to caesarean section on day 28 of pregnancy. Effects of test substance on dams and embryonal development of fetuses were examined. No treatment-related changes in clinical signs and necropsy findings of dams were observed in all groups. At 80 and 320 ng/kg, a significant decrease in food consumption followed by a loss in body weight was found.

  • LBD-007, a newly developed recombinant human interferon alphaA, was at dose levels of 0.3 $\times$$10^6$ , 6 $\times$ $10^6$ and 12 $\times$ $10^6$ IU/kg/day administered subcutaneously to pregnant New Zealand White rabbits during the organogenetic period. Cyclophosphamide was used as a positive control. All pregnant females were subjected to the caesarean section on day 28 of pregnancy. Effect of test substance on dams and embryonal development of fetuses were examined. 1. No treatment-related changes in clinical signs, food consuption, body weight and necropsy findings of dams were observed.
