Human Adjuvant Disease(HAD) is a connective tissue disease occuring after cosmetic surgery with a foreign substance. It was first reported by Miyoshi in 1964. There have been specific connective disorders such as systemic lupus erythematosus, rheumatoid arthritis, progressive systemic sclerosis and mixed connective tissue disease. Scleroderma is the single most commonly reported disease. A 55-year-old woman was seen for evaluation of dypnea. Four years previously, she underwent cosmetic surgery with silicone injected directly into eyelid, forehead, both hand and monspubis. The patient presented the classic feature of systemic sclerosis and pericardial effusion. Following pericardiocentesis, she felt somewhat better and became less dyspneic. Seventeen days later, however, she progressively deteriorated and died in spite of intensive medical therapy and supportive care.

Immunohistochemical staining on paraffin sections for S-100 protein improved diagnostic accuracy for melanocytic tumor. But specificity of S-100 protein in the diagnosis of melanocytic tumor is very low, because S-100 protein was also expressed in neurogenic tumor and salivary gland tumor. To investigate a specific tumor marker for the malignant melanoma, immunohistochemical staining for HMB-45 and S-100 protein was performed on the paraffin sections of 25 cases of malignant melanoma and 46 cases of nevi. Positive reaction for HMB-45 and S-100 protein was diffusely identified in the cytoplasm of tumor cells. Positive ratio for HMB-45 was 100% in malignant melanoma, 92% in junctional component of compound nevus and 0% in intradermal nevus. Positive ratio for S-100 protein was 92% in malignant melanoma, 100% in compound nevus and 100% in intradermal nevus. The sensitivity and specificity for HMB-45 in malignant melanoma were 100%, but those for S-100 protein were 92% in sensitivity and 86.7% in specificity. These results indicate that HMB-45 has a high sensitivity and specificity for malignant melanoma cells and it can be quite useful for the histopathological diagnosis of malignant melanoma.

5.Shear bond strength of orthodontic bonding resins to porcelain; an in vitro study.
Korean Journal of Orthodontics 1992;22(1):43-65
Bonding orthodontic adhesive resins to glazed porcelain surface is not attainable. The aim of this investigation was to examine, in vitro, the effect of three methods of porcelain surface pretreatment on the shear bond strength of orthodontic adhesives, and to compare the shear strength of orthodontic bracket bonding to porcelain surface by the best results that to human enamel. Porcelain disks (Ceramco((TM)) and Vita((TM))) baked in the laboratory were roughened by sandpapers, #320, #600, #800, #1000 and #1200, and were pretreated with silane and dried at the various temperatures, room temperature, 50degreesC, 70degreesC and 90degreesC, and were etched by 3% hydrofluoric acid solution for 1, 3, 5, 7, and 9 minutes, orthodontic adhesives (System 1 +((TM)) and Unite((TM))) were applied on them, and shear bond strengths were measured by Instron. The best results of pretreatment of each method were determined by the shear bond strengths. Again, porcelain disks were pretreated by the determined best results and human enamel were etched by 37% hydrofluoric acid solution, orthodontic brackets were bonded on them by the orthodontic adhesives, and the shear bond strengths were measured and compared between them. 1. Roughening porcelain surfaces with coarse sandpaper (#300) showed higher shear bond strength than that with finer sandpapers, but it (22.44 Kgf/cm2) was distinguishably low compared to that from etched human enamel (144.11 Kgf/cm2). 2. There were disparities in shear bond strengths upon the orthodontic resins, which was presumably related to the contents of fillers in orthodontic adhesive resins. Also there were disparities in shear bond strength upon the porcelains which had different composition. 3. Silane enhanced the shear bond strength of orthodontic resins to porcelain surfaces (25.20 Kgf/cm2 at 50degreesC), which was markedly low compared to that from etched human enamel. 4. Etched porcelain surface with 3% hydrofluoric acid solution for 1 to 9 minutes showed no difference in shear bonding strength of orthodontic adhesive resins. Shear bond strength from etched porcelain (97.43-120.72 Kgf/cm2) were as high as clinically available, but low compared to that from etched human enamel. 5. Roughening with #300 sandpaper and etching by 3% hydrofluoric acid followed silane application on porcelain surface showed lower shear bond strength than etched human enamel, but were as high as clinically useful. 6. The results suggest that etching porcelain surface by 3% hydrofluoric acid solution might provide comparatively high shear bond strength as much as clinically favorable.

Surgical endarterectomy has been shown to be superior to medical treatment in the management of severe carotid stenosis. Endarterectomy, although effective, does have limitations, and percutaneous transluminal angioplasty with stent may offer an alternative modality of treatment. We report on a patient with severe coronary disease that femoral arterial cannulation was not possible due to aorto-femoral shunt operation and absent pulse. The transradial approach was used for aortography, bilateral carotid angiography and successful elective stent deployment in the left internal carotid artery. The transradial approach might be useful alternative in case of problems with femoral approach.

The present study has been conducted to assess the possible mechanism of cultured rabbit lens epithelial cell(LEC) damage and generation of oxygen free radicals after UVB exposure as well as to investigate the role of antioxidants to the survival rate of epithelial cells. Cultured rabbit LECs were exposed to various fluences of UVB radiation. The release of oxygen radicals(superoxide radical and hydrogen peroxide) and the activity of antioxidants(SOD, catalase) were also measured. The protective effects of various antioxidants on LECs damage after UVB exposure were measured. UVB radiation brought about a decrease in the survival fraction of cultured rabbit LECs. Exposure of the cells to fluences of 400 mJ/cm2, 1,600 mJ/cm2 and above 2,400 mJ/cm2 of UVB radiation resulted in 50%, 10%, nearly 0% in cell survival fraction, respectively. Cultured rabbit LECs exposed to UVB and hydrogen peroxide. The activity of intracellular SOD(esp. Cu, Zn-SOD) was significantly increased, but the activity of intracellular catalase was not changed. Antioxidants pretreatment(SOD, catalase, purpurogillin and allopurinol) ameliorated the cytoxoxic effect of UVB on the cultured rabbit LECs. These rusults indicate that the release of oxygen radicals are enhenced by exposure of LECs to UVB radiation. The oxygen radicals seem to play a specific role in the cytotoxic effect of LECs after UVB exposure.

Coronary stent embolization is a rare event but may result in clinically relevant cardiac ischemia or peripheral embolization during the procedure. We report a case of systemic embolizations of two coil stents during the primary PTCA in acute myocardial infarction, who were treated successfully with a double wire helix technique and a gooseneck snare. Although in our experience this rare complication did not produce any clinical complications, care should be taken to prevent this possibility, especially in patients with significant vessel tortuosity, calcification, total occlusion, or mild stenosis proximal to the target lesion.

We observed sisters who showed the classical symptoms and signs of the pulseless disease, which were the absence of the radial pulsation, arteriovenous anastomoses around the optic disc and intermittent dizziness. The main changes in the fundus of them were as follows. 1) wreath-like anastomoses of the central retinal artery and vein around the disc. 2) almost complete disappearance of the visible vessels beyond five disc diameters from the optic disc. 3) multiple microaneurysms and hemorrhages.
