Carbon monoxide is colorless, oolorless, tasteless and non-irritating gas produced by the incomplete combustion of carbonaceous rnaterial. It combines with hemoglobin and displaces oxygen because the affinity of hemoglobin for carbon monoxide is two hundred times greater than oxygen. Symptoma and signs of carbon monoxide poisoning include headache, nausea, vomiting, dizziness, collapse, unconsciousness, blindness, convulsion, coma and skin lesions. Recently we have observed seven patients with carbon monoxide poisoning who expressed cutaneous syrnptoms. In this work we investigated the pathogenesis of cutaneous manifestations of carbon monoxide poisoning through clinical, histologic and electronmicroscopic study. The results are summarized as follows: 1. Mental states of the patients were comatose in two, Semicomatcse in two, stuporous in two, and drowsy in one patient. In routine laboratory tests, we observed elevated blood sugar in six, elevated sorum creatinine phosphokinase in four and abnormal findings in urinalysis in all patients. 2. Cutaneous lesions were vesicobullae, plaque or swelling, erythema, gangrene and 'ulceration in order of frequency and located in the dependent areas in six caies. 3. Histopathologically, the sites of the bullae were subepidermal in four cases and intraepidermal in. one case and there was one case with ulceration. 4. In electronmicroscopic findings, secretory and ductal cells showed degenerative

Lipomas are common soft tissue that are usually located in the subcutaneous tissue. And intramuscular lipomas commonly arise in the upper and lower extremities, where they usually involve the large muscles. Intramuscular lipoma, also referred to as an infiltrating lipoma, is an unusual benign slow growing tumor composed of mature fat cell interdigitating with skeletal muscle. However, intramuscular lipomas are exceedingly rare in the face. We have been experienced a case intramuscular lipoma that located in the malar area. Because of the rarity of these tumors and their propensity to recur without adequate surgery, the case report is presented here. Achievement of surgical margin is essential as the recurrent rate may be as high as 15% to 62.5% without complete excision.

We report 2 cases of midface defect reconstructed with latissimus dorsi myocutaneous free flap. In these cases, the main points to cover the defects were as follows: 1. For the contour of zygoma and maxilla, it was well preserved without bone graft which was not used for second stage reconstruction. In first case, for application of artificial eyes and in second case, for operation after full development. 2. For the drainage of paranasal sinuses, we made the nostril with skin graft, and it was well preserved without any complications during follow up. 3. It was sufficient to cover the defect with latissimus dorsi muscle well designed before surgery and thick enough to fill the defect. 4. In second case, the remained defect of palate and maxilla was not covered for the appropriate reconstructions after full development. In conclusions, we experienced two cases of midface defect reconstructed with latissimus dorsi myocutaneous free flap without any complication and with good results.

Desquamative gingivitis is characterized by a diffuse erythema of the free and attached gingiva associated with areas of vesiculation, erosion, and desquamation. Desquamative gingivitis is not a distinct disease entity but represents a reaction pattern of the gingiva to various stimuli. Pemphigus vulgaris, cicatricial pemphigoid, and lichen planus may presents as desquamative gingivitis. We observed 3 patients whose disease was limited to the gingiva, and studied them by light and direct immunofluorescence microscope. We classified them according to clinical, histologic, and immunopathologic observations. Identification of the underlying causes of desquamative gingivitis is of utmost importance and is dependent upon clinical, histologic, and immunologic criteria.

8.Microglia in the normally aged hippocampus.
Laboratory Animal Research 2011;27(3):181-187
The hippocampus plays important roles in the regulation and combination of short and long term memory and spatial navigation with other brain centers. Aging is accompanied by a functional decline of the hippocampus and degenerative disease. Microglia are major immune cells in the central nervous system and response to degenerative changes in the aged brain. In this respect, functional and morphological changes of the hippocampus have been closely related to microglial changes during normal aging with or without disease. Therefore, in this review, we discuss morphological and functional changes of the hippocampus and microglia in the aging brain.

BACKGROUND: The pathogenesis of atopic dermatitis is still unknown. Many reports have suggested that the house dust mite antigen may play a role in the pathogenesis of atopic dermatitis. The IgG4 allergen-specific subclass has been considered to be involved both in allergic reactions and associated with the appropriate response to allergen-specific immunotherapy. OBJECT: The purpose of this study was to evaluate the positive rate of the allergic prick test to D. farinae and the levels of D. farinae-specific IgE and Ig64. METHODS: We performed the allergy prick test, RAST for D. farinae-specific IgE and ELISA for D. farinae-specific IgG subclasses and compared the values between atopic dermatitis patients and normal controls. RESULTS: 1. D. farinae was the most common allergen in patients with atopic dermatitis and the positive rate of the allergic prick test was 61.0%. The positive rate of the allergic prick test and the positive rate to D. farinae increased as c]inical grading increased. 2. The Positive reaction rate of D. farinae-specific IgE(RAST) in those with atopic dermatitis was 68.8% and increased as the positive reactions of the allergic prick test to D. farinae and chnical grading increased. 3. Among the IgG subclasses, only the level of D. farinae-specific IgG4 was significantly higher in atopic dermatitis than normal controls. 4. The level of D. farinae-specific IgG4 showed a tendency to decrease in accordance with the clinical severity grades. CONCLUSION: These results suggested that D. farinae might play an important role in the development of atopic dermatitis and well-designed studies should continue to be performed in order to delineate the biological significance of IgG4.

A 6-day-old female infant had generalized superficial pustules which evolved into pigmented maucles, many of which had a peripheral collarvtte of scale. Histopsthologic stadies showed intracormeal aggregates of neutrophils. The appearance of the lesions and histopathologic finding fitted transient neonal pustular melanosis.
