Pleomorphic adenoma of the palate is the most common of all intraoral salivary tumors. It can occur at any age but it presents most commonly in the 40∼60 age group, and there is no significant sex preponderance. It grows slowly and is usually painless, firm, well-circumscribed nodule. Because of high rate of recurrence, extra-capsular excision including the overlying mucosa and margin of normal tissue is recommended. We report 10 cases of palatal pelomorphic adenoma which have been successfully treated by extra-capsular excision. The surgical defects smaller than 3㎝ in diameter were covered with palatal acrylic splint for the secondary healing. The larger defects were repaired using palatal island flap in 3 cases, rotation flap and buccal fat graft in each 1 case. No patient showed any recurrence or malignant change during the mean follow-up period of 4 years and 9 months. These repair methods seem to be simple, reliable and uncomplicated procedures in the palatal surgical defects.

The skin flap, which has been frequently used in the maxillofacial soft tissue defects, can be failed due to insufficient blood supply to the flap. To increase its survival rate, antithrombotic agents has been used. The agents have, however, been restrictly used because of their side effects, such as bleeding tendency or hematoma formation on the operation site. The present study aimed to the effect of pentoxifylline, aspirin, and heparin on the skin flap survival rate and bleeding tendency. Twelve adult white rabbits, weighing about 2.0 kg, were used. Five random skin flaps, which is 1mm thickness, were prepared on the dorsal surface of each rabbit by using 1.5 X 7.5 cm prefabricated template. The animals were divided into 4 groups on the basis of drugs used: Control group, animals in which no drug was given (n=3); Pentoxifylline group, animals in which pentoxifylline was given intraorally (n=3); Aspirin group, animals in which aspirin was given intravenously (n=3). On the 3rd and 7th day after operation, prothrombin time (PT) and activated partial thromboplastin time (aPTT) were measured to evaluate the bleeding tendency. The animals were sacrificed on the 7th day and the mean skin flap survival rate of each group was measured. The results obtained were as follows : 1. The skin flap survival rates of pentoxifylline (84.3±7.9%) and heparin (79.5±10.9%) groups were significantly increased, compared with control group (68.0±10.8%)(ㅔ<0.05). The survival rate of aspirin group (73.0±11.1%) was not increased. 2. In bleeding tendency, the PT values were prolonged in heparin and aspirin groups at the 3rd day after operation (p<0.05), and prolonged in order of heparin group, aspirin group, and pentoxifylline group at the 7th day after operation. The aPPT values in heparin and aspirin groups were also prolonged at the 3rd day after operation (p<0.05), and prolonged in order of Aspirin group. Heparin group, and Pentoxifylline group at the 7th day after operation. These results suggest that pentoxifylline may be the most useful drug among three drugs to increase skin flap survival rate and less increase the bleeding tendency.

세계적으로도 '92년 리우 환경회담 이후 점차적으로 환경에 대한 규제가 엄격해지고 있고, 선진국에서는 recycling과 연계되어 모든 분야의 과학발전이 이루어지고 있다. 더구나 최근 EC의 유럽회의에서 가까운 시기에 역내에서 사용되는 포장용기의 90%이상을 재생사용토록 의무화하는 새로운 리사이클링 규정안을 통과시켰으며 국내에서도 쓰레기 종량제가 전국적으로 실시되어 폐플라스틱의 수거, 처리 방안이 문제시 되고 있다. 이러한 상황에서 적절한 대비책으로 폐플라스틱의 수급현황, 자원화전망 그리고 개발중인 여러 가지의 처리 방안을 제시하였다. 그리고 지금까지는 아무리 우수한 기술이 있어도 경제성이 없으면 상업화가 이루어지지 않았으나, 향후의 리사이클 방향은 조금씩 바뀔 것으로 생각되며 이는 우선 플라스틱의 발생 및 사용량의 절약에서 시작하여 재생이용을 추진하고 최종적으로 소각에 의한 열이용의 순서로 이루어져야 할 것이다.

This is clinical study on 113 patients who were treated for parotid tumors at Chonnam National University Hospital over a period of 5 years from January 1996 to December 2000. The results were as follows ; The mean ages were 42.6 years old (12∼73 years) for benign parotid tumor patients and 43.9 years old (2∼74 years) for malignant patients. The ratio of male to female was 1:2 in malignant parotid tumors, but there was no difference in benign tumors. There was no difference in mean mass size and duration of illness between benign and malignant tumor patients. The combined usage of fine needle aspiration biopsy and computed tomogram was common as the diagnostic methods of parotid tumor. The parotid tumors were commonly located in the superficial lobe (69%). The ratio of benign and malignant tumors was 4:1. The most common benign tumor was pleomorphic adenoma (72% of benign tumor), followed by Warthin's tumor and monomorphic adenoma. The most common malignant tumor was mucoepidermoid carcinoma (45% of malignant tumor), followed by adenoid cystic carnoma, carcinoma ex pleomorphic adenoma, and adenocarcinoma. The most common operations were superficial parotidectomy (72%) for benign parotid tumor and total parotidectomy (45%) for malignant tumor. The most common postoperative complication was temporary facial nerve weakness (82%), followed by Frey's syndrome (14%) and permanent facial palsy (4%). Postoperative radiation therapy was done in 12 patients (60%) and the mean radiation dose was 5550±620 cGy. Of 113 cases, tumor recurrence developed in 12 cases (10%). These results suggest that the successful management of parotid gland tumors needs adequate surgical treatment on the basis of knowledge of parotid gland anatomy and preoperative diagnosis.

자동차 산업의 부산물로 발생되는 각종 폐고무류와 폐타이어 그리고 일반 제화공업이나 공산품의 제조공정에서 필연적으로 발생되는 합성 천연고무 폐기물은 국내에서만도 년간 16만톤이 발생되는 것으로 추정되고 있어 이로 인한 환경 및 사회적인 문제가 이미 심각한 상황에 도달해 있는 실정이다. 이러한 상황은 자동차 산업의 선진국인 미국의 경우에서 뿐만아니라 국토가 비좁은 구주의 경우도 폐타이어등 폐고무류에 의한 문제가 사회적으로 점차 심각하게 대두되고 있어 이의 처리에 대한 당위성은 이미 오래전부터 제기되어 왔다. 따라서 국내에서만도 년간 1200만개 이상 발생되는 폐타이어로 인한 환경문제를 해결하고 아울러 이를 에너지로 또는 유용한 자원으로 재환원하여 사용함으로써 국가에 크게 이바지할 수 있는 기술에 대한 실용화 연구는 꼭 필요하다.
