The sublabial approach for transseptal transsphenoidal surgery of pituitary tumors has been the most popular procedure since Cushing first introduced this technique in early 1900's. In recent years, various modifications for transseptal route and their obvious advantages over the sublabial approach have been reported. Currently, in our institute, the preferred method is the external rhinoplasty approach, suggested by Braint and descried by McCurdy. After experiencing 54 cases since 1995 DEC, we found this technique simple, providing good exposure and short distance for instrumentation, preserving nasal tip projection, avoding postoperative numbness of upper teeth and especially beneficial to revision surgery when septal cartilage has been removed by a previous sublabial approach and to surgery for acromegaly patients.

PURPOSE: Carpal boss of the hand is a rare lesion. This study was conducted to recognize the clinical patterns of this disease entity and to evaluate the diagnosing modalities, differencial diagnosis, and results after operative treatment. MATERIALS AND METHODS: We report upon 7 operative cases of carpal boss of the hand. There were 5 females and 2 males with an aver-age age of 35.4. The mean follow up period for patients in this study was 15 months. The dominant hand was affected in 4 cases and the small ganglion was associated with the carpal boss in 4 cases. RESULTS: The average duration of conservative treatment before surgical treatment was 8.3 months. All of the patients had taken NSAIDs prior to surgery and 4 patients had received a corticosteroid injection at least once. All of the patient had surgical treatment and complete symptomatic relief was achieved in 6 cases. One patient had no symptomatic relief. CONCLUSION: We operated upon patients who did not respond to conservative treatment or in whom the carpal boss associated with a ganglion, 5 of 7 cases showed a satisfactory result. In view of these results, we recommended that operative treatment should be con-sidered in such cases.

OBJECTIVE: The transfection efficiencies of gynecologic cancer cell lines were investigated by different mediated transfection methods using recombinant LacZ plasmid (pRcCMVLacZ and pAAVCMVLacZ). METHODS: In this study, the gynecologic cancer cell lines were used CaSki, SiHa (cervical, HPV16+, wild type p53 gene), HeLa, HeLa S3 (cervical, HPV18+, wild type p53 gene), C33A, HT3 (cervical, HPV-, p53 mutant), HckE6/E7 (cervical, HPV16 immortalized keratocyte), PA-1 (ovary, wild type p53), SKOV-3, A2774 (ovary, p53del) and OVCAR-3 (ovary, p53 mutant). The pRcCMVLacZ and pAAVCMVLacZ plasmid transfection were performed by using liposome system such as Ca2+-phosphate, Fugen6(TM), Lipofection(TM), Lipogen(TM) and N-stearyl lactobionamide (N-SLBA) with X-gal staining. The LacZ gene was used the reporter gene for the transfection efficiencies evaluation. RESULTS: Each of cell lines were showed different transfection efficiencies by Ca2+-phosphate, Fugen6(TM), Lipofectin(TM), Lipogen(TM) and N-SLBA. Each of cell were revealed that HeLa S3, HT3 and A2774 were high transfection efficiency using the pRcCMVLacZ by the Lipogen(TM), SiHa, HeLa, QGU, OVCAR-3 and PA-1 were high efficiency using the pAAVCMVLacZ by Lipofectin(TM), CaSki was high efficiency using the pRcCMVLacZ by the Lipogen(TM), A2774 and Cx16.2 were high efficiency using the pRcCMVLacZ by the Lipofectin(TM), SKOV-3 and HkcE6/E7 were high efficiency using pAAVCMVLacZ by the Lipogen(TM). CONCLUSION: As a result, We proved that each of cell lines differed trasnfection efficiencies according to mediated transfection and recombinant LacZ plasmid style. Above all, Lipofectin(TM) mediated transfection was showed high efficiency at the most of cell lines.

BACKGROUND: The basic treatment of malignant tumors is surgery, radiotherapy, chemotherapy. Even though, the object of these treatments is to kill cancer cells, they have limitations. So, in future studies of treatment of cancer, we should look into increasing human immune response using gene therapy in order to induce damage to tumor cells. OBJECTIVE: The cell growth inhibitory effect of cervical cancer cells was investigated by direct transfection using liposome(pRcCMVp53/lipofectin). and by indirect transfection using Adenovirus(AdCMVp53). METHODS: The cervical cancer cell lines we used in this study were HPV16 positive, having inhibitory gene, wild p53 gene, CaSki, SiHa, HPV18 positive HeLa, HeLaS3 and HPV negative C33A, HT3, LacZ gene was used as the marker gene for the transfection efficacy. Direct transfection was done by using lipofectin (pRcCMVp53/lipofectin) and indirect transfection was done by using virus, AdCMVp53. The effect of tumor cell growth inhibition was measured by cell counting assay. RESULT: Inhibition of growth of cervical cancer cells in cell counts of direct transfection was CaSki(88.5%), SiHa(59.1%), HeLa(86.0%), HeLaS3(78.0%), C33A(91.3%) and HT3(74.0%). Inhibition of growth of cervical cancer cells in cell counts of indirect transfection was CaSki(97.4%), SiHa(91.6%), HeLa(95.8%), HeLaS3(99.7%), C33A(97.3%) and HT3(87.4%). CONCLUSION: The inhibition of cell growth of cervical cancer cells by direct and indirect transfection was significantly reduced, and showed little differences depending on the type of cells. These results will have a great meaning in treating cervical cancer patients using gene therapy by direct or indirect transfection
