Tuberous sclerosis is usually characterized by the triad of epilepsy, mental deficiency and adenoma sebaceum of the face. A 18-year-old girl was reported in which retinal phakoma, angiofibromas of the face and history of epilepsy occured with normal intelligence. On X-ray film multiple calcifications were, found in skull series. Also literatures were reviewed.

When blow-out fracture repair is performed, many implants including Silastic, Supramid, Porous polyethylene and others have been used to pervent reherniation of orbital tissue. Complications associated with implants include implant extrusion, orbital infection, fistula formation, implant migration, extraocular muscle entrapment, globe elevation, protosis and orbital cyst formation. The latter was known as a rare late complication of blow-out fracture repair. We report two cases of orbital cyst which developed after blow-out fracture repair with alloplastic implants. These patients developed diplopia and unliateral proptosis 7 and 10 years after repair of blow-out fracture, respectively. In these cases, orbital CT scan revealed retrobulbar cyst-like structures surrounding the orbital implant. At sufgery, a fibrous capsule surrounded the previously inserted orbital implants and was filled with dark brown mucoid material in both cases. These cysts were lined by squamous epithelium with cholesterol cleft and hemosiderin laden macrophage collection. Proptosis and diplopia were resolved after surgical removal of the cyst. These cases illustrate that it is important for us to be aware of the complication of late cyst formation around alloplastic implants after repair of blow-out fracture.

Each three rabbit corneas were stored in McCarey-Kaufman medium at 4 degrees C for 5, 9 and 14 days and used as donor materials in 6mm partial penetrating corneal allografts. These results were compared to that group of penetrating keratoplasties with corneas stored conventional moist chamber at 4 degrees C for 5 days. All the M-K media stored corneas for 5 and 9 days were in clear graft after keratoplasty during the observation period of 6 months but the corneas stored for 14 days were developed eventvally irreversilde opaque after grafts. At 6 months after keratoplasties allthe rabbits eyes were enucleated and sectioned for histopathologic study of endothelia with the light and electron microscopes. Endothelia of the corneas stored for 5 and 9 days showed rarely endothelial degenerative changes. But the corneas stored up to 14 days showed significant changes including of disappearanee of most endothelial membranes and cytoplasms in light microscopies and swelling of nucleus, dispersed chromatin clump, multiple small and large vacuoles in cytoplasm and occasional autolysis of cytoplasm were observed in electron microscopies.

The authors ana lysed statistically seventy-five cases of the eye injuries in childhood under the age of 20 years old during a full year of 1972. 1. Incidence of eye injuries under 20 years old was about 1.1% of total out-patients and 39.9% of total eye injuries. 2. The most common objects to the injury were iron pieces or iron made materials (24%) such as needle, nail, flying iron piece, toy, wire and bar etc. 3. The most common nature of eye injuries was traumatic cataract (14.2%) 4. Seasonally the high peak of injuries was in summer (33.3%) and winter vacation (30.7%) 5. Blindness(under20/200 of corrected VA) was occured finally in 10.8% of total 75 cases.

BACKGOUND: General anesthesia was known to induce hypercoagulable status during major orthopedic surgery. This study was designed to analyze effects on hemostatic reponse in patients receiving general or spinal anesthesia for total knee arthroplasty, using the thromboelastography (TEG). METHODS: Among women that were scheduled to total knee arthroplasty without both no medical or surgical history and no chronic systemic disorder, ten patients were selected at each group (general or spinal anesthesia). TEG was measured at 4 times around the each surgery (before skin incision after induction, before bone manipulation, after bone manipulation, 1 hour after operation). RESULTS: There was no difference statistically between two groups in first and second measures of TEG. But, significantly different r time, k time, alpha angle, and maximum amplitude was noted between two groups after bone manipulation and 1 hour after operation (P < 0.05). Conculusions: After the release of tourniquet following bone procedures the patients receiving general anesthesia had relatively high hemostasis compared with the spinal anesthesia group. This phenomenon was also noted in 1 hour after operation.

PURPOSE: The medial meniscus is injured much more than the lateral meniscus. Because the medial meniscus is much larger in diameter, is thinner in its periphery and narrower in body than the lateral meniscus, and does not attach to either cruciate ligament. We evaluated correlations with sites of tear and history of trauma. METHODS AND MATERIALS: We reviewed retrospectively in 43 patients with meniscal tears on MRI(51 cases) and correlated them with history of trauma. RESULTS: The most common site of injury was the posterior horn of the medial meniscus(32/51), but high incidence of lateral meniscal tear compared with previous reports was seen. In the cases which had history of trauma, the posterior horn of medial meniscus was most commonly injured(26/34) and 5 meniscal tears were combined with meniscal tear in the other site. The tear in the anterior horn of the medial meniscus was seen only in a patient which had history of trauma and combined with meniscal tear in the other site. But in the meniscal tears without definite history of trauma, the incidence of meniscal tear was different from the meniscal tear with history of trauma. The incidence of lateral meniscal tear(11/17) was highter than medial meniscal tear and the posterior horn of lateral meniscus was commonly injured. CONCLUSION: We concluded that the medial meniscus was commonly injured, especially posterior horn, but in the cases which had no definite history of trauma, the lateral meniscus was commonly ipjured. An awareness of prevalent site of meniscal injuries may be helpful in the diagnostic interpretation of MR imaging of knee.

Recently, an increasing number of bisphosphonate related osteonecrosis of the jaw(BRONJ) is being reported. A guideline has been already established in the US, but it does not seem to be fully recognized by clinicians in Korea. Therefore, a survey study was done to inform and have clinicians realize the seriousness of BRONJ. 1,341 practitioners were randomly selected out of 13,405 practitioners(by Feb of 2008, KDA) in Korea. A questionnaire was given to them between May to July in 2008. Questions were designed to investigate each respondent's experience term years in the clinic, occupation, speciality, awareness on risk of bisphosphonate, experience on treating osteonecrosis patients, awareness about the guideline on BRONJ suggested by AAOMS and whether if they ask about bisphosphonate medication history to patients before invasive treatment. 45.1% of the clinicians have reported on experiencing delayed healing on bone exposed site after extraction both in the maxilla and the mandible. However, clinicians have asked the patients whether if they are on bisphosphonate or not in only 15.1% of these cases. 56.5% of the clinicians simply knew about BRONJ but only 28.9% of the clinicians were aware that bisphosphonate can cause osteonecrosis after invasive dental treatment. Only 19.3% knew about the contents of guideline on BRONJ and 57.2% were aware of the seriousness of BRONJ. Clinicians with shorter clinical experience term were more aware of BRONJ and the guideline on BRONJ than the experienced clinicians. But awareness of the possibility of BRONJ after invasive dental treatment were about the same regardless of their clinical experience. The results show that Korean clinicians need to be more aware about BRONJ. Data on BRONJ cases in Korea should be collected and provided with additional education to let Korean clinicians know and be more aware about BRONJ

A number of case reports on occupational asthma caused by herbal medicines have been issued, for example, on Sanyak, Chunkung, Banha, and Brazilian ginseng. Recently, cases of occupational asthma induced by Sanyak and Korean ginseng have been reported, but the pathogenic mechanisms involved are unknown. This study was carried out to evaluate the immunologic mechanism underlying Korean ginseng-induced occupational asthma. A patient engaged in Korean ginseng wholesale was referred for recurrent dyspnea, wheezing, and nasal symptoms, which were aggravated at work. Allergen bronchial provocation testing to Korean ginseng extract showed a typical immediate response, and skin prick testing to Korean ginseng extract also showed a strong positive response. Moreover, serum-specific IgE levels to Korean ginseng extract were significantly higher than in controls. Enzymelinked immunosorbent assay (ELISA) inhibition tests showed a dose-dependent inhibition by Korean ginseng, but not by Dermatophagoides farinae, wheat flour, or Chinese balloon flower. Sodium dodecylsulfate-poly-acrylamide gel electrophoresis (SDS-PAGE) and immunoblotting revealed four specific Immunoglobulin E (IgE) binding components at 26, 30, 47, and 60 kDa, which were not bound by control sera. These results strongly suggest that occupation asthma induced by Korean ginseng is induced via an IgE-mediated mechanism.

BACKGROUND: Mucosa-associated lymphoid tissue(MALT) lymphoma has an indolent natural course. However, extra-gastric MALT lymphoma has been reported to have more frequent relapses and shorter time to progress than gastric MALT lymphoma. We performed this study to analyze clinical features of extra-gastric MALT lymphoma. METHODS: We retrospectively reviewed the medical records of the patients who were diagnosed as extra-gastric MALT lymphoma at the Samsung Medical Center from March 1995 to January 1999. The survival was analyzed by Kaplan-Meier method. RESULTS: During the study period, extra-gastric MALT lymphoma was diagnosed in 50 patients. The median age was 51(28-87)yaers. The male to female ratio was 22:28. Commonly involved sites were conjunctiva (25/50, 50%), lung (6/50, 12%) and intestine(6/50, 12%). Histopathologically, low to high grade ratio of extra-gastric MALT lymphoma was 47:3. Among 41 patients who were staged, 32 patients(78%) had stage I or II and 9 patients(22%)had stage IV. B symptoms were seen in only 3 patients. Bone marrow involvement was observed in 4 patients. The duration of median follow up was 22 months. The 1-year and 2-year survival rates were 95.1% and 91.4% retrospectively. CONCLUSION: Majoity of our cases with extra-gastric MALT lymphoma had low grade, early stage, good treatement reponse and good prognosis.

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.
