Adult Clonorchis sinensis were collected from the biliary passage of nine cases of medico-legal autopsies. The worms were washed repeatedly with tap water and rinsed twice with physiological saline. Incubation took place in Tyrode's medium in order to recover live worms. The number of worms surviving in the medium was determined. The rate of surviving worms showed an unexpectedly high percentage (22.8%) in those cases autopsied 2 days after death. The surviving worm burden dropped sharply to 6.3 and 9.2 percent for those samples taken 5 days after death.

We observed a 51-year-old male, who developed depigmented patches on the lower abdomen after photochemotherapy(PUVA) of psoriasis without evidence of phototoxic reaction. The depigmented patches did not orginate from the sites of previous psoriatic lesions. Fontana-Masson stain of the biopsy specimen revealed nearly absent melanin pigments in the epidrmis of the hypopigmented patch, while lots of pigments were obsereved on the surrounding hyperpigmented area. Electron micrograph showed no melanocytes in the hypopigmented patch. Thus we report this case as having vitiliginous patches induced by photochemotherapy of psoriasis.

PURPOSE: To find the rebleeding factors in bronchial arterial embolization for treatment of hemoptysis, a retrospective study was performed. MATERIALS AND METHODS:Medical records, anglographic findings and embolic materials of 35 patients who had undertaken arterial embolization for control of hemoptysis were reviewed. The period of follow-up for rebleeding was from 3 to 32 months after arterial embolization. We investigated the anglographic findings of extravasation, neovascularity, intervascular shunt, aneurysm and periarterial diffusion. Neovascularity was classified as mild(numerable neovascularity) and severe(innumerable). RESULTS: Rebleeding occured in 15(43%) among 35 cases. Only two of 11 cases with no past episode of hemoptysis showed recurrence, while 9 of 15 cases who had more than three episodes did. Severe neovascularity were seen in 11 of 15 recurred cases, but seven of 20 non-recurred cases showed severe neovascularity. More than three anglographic findings representing hemoptysis were seen on 11(73%) among recurred 15 cases and seven(35%) among non-recurred 20 cases. The lesion was supplied by more than two different arteries on 8(54%) of the recurred cases, but only three(15%) of the non-recurred cases. Six of seven cases persistent neovascularity after arterial embolization were recurred. CONCLUSION: The history of repeated hemoptysis, severe neovascularity, variable anglographic findings, and post-embolization persistency of neovascularity were the factors related with the rebleeding after arterial embolization for hemoptysis. Careful and active arterial embolization are required on these conditions.

The purpose of this study was to evalute the corrosion resistance of chemically and thermally recycled metal brackets. In vivo, two types of recycled metal brackets and new brackets were directly bonded for 1 year, and then the microstructure of bracket surface was examined by S.E.M. (J.S.M.-840 Scanning Electron Microscope, Japan). The following results were obtained. 1) The microstructure of new and chemically recycled metal bracket surfaces showed regular structure without island formation and recrystallization; and after 1 year, the same appearance except some scratches. 2) The microstructure of thermally recycled metal bracket surfaces showed a beginning of island formation and recrystallization by annealing, and after 1 year, a typical corrosive appearance, completely island formation with some metal grains by recrystallization. 3) Chemically recycled metal brackets showed better corrosion resistance than thermally recycled metal brackets.

Studies were conducted to determine the ecology of the snail, Parafossarulus manchouricus, the seasonal variation of the snail population, and the infestation rates of these snails with the cercariae of digenetic trematodes, in the snail habitat of river Kumho, in Dongchon of Taegu city, in Kyungpook Province, Korea, from 1975 to 1979. The earliest time the snails were found was early in April every year. At that time the water temperature ranged from 13 to 14 degrees C. The population density of snails ranged from 2 to 8 per square meter. The highest population density of snails was encountered in late June and the water temperature was between 24 and 26 degrees C. The snails disappeared in early and mid-November, when the water temperature dropped to 10-13 degrees C. The average snail population in June was 115.9 per square meter in 1975 but in 1976 dropped abruptly to 30.5 and remained at approximately the same level in 1977. It then decreased at considerably lower rates, with the average of 18.7 in 1978 and 14.5 in 1979. The snails collected in the habitat were examined for the presence of cercariae of digenetic trematodes. Of these, four species, Clonorchis sinensis, Cyathocotyle orientalis, Exorchis oviformis, and Loxogenes liberum were found. The most frequently liberated cercaria was L. liberum 43.3 per cent, followed by E. oviformis 6.2 per cent and C. orientalis 1.5 per cent. The least frequently liberated was C. sinensis 0.1 per cent. In the monthly liberation rates for larval trematodes, the higher rates were observed in June, July and August every year, and the cercarial rates for Clonorchis sinensis, Cyathocotyle orientails and Exorchis oviformis demonstrate a fairly consistently fluctuating downward trend over the five-year period, except for Loxogenes liberum. Summarizing the results, this study indicated that the population density of snails in the habitat and the infection of the snail with the cercariae of digenetic trematodes has decreased over the five-year period from 1975 to 1979.

PURPOSE: To evaluate outcome and morbidity in patients with vulvar cancer treated with radiotherapy, concurrent chemoradiotherapy or postoperative radiotherapy. MATERIALS AND METHODS: The records of 24 patients treated with radiotherapy for vulvar cancer between July 1993 and September 2009 were retrospectively reviewed. All patients received once daily 1.8-4 Gy fractions external beam radiotherapy to median 51.2 Gy (range, 19.8 to 81.6 Gy) on pelvis and inguinal nodes. Seven patients were treated with primary concurrent chemoradiotherapy, one patient was treated with primary radiotherapy alone, four patients received palliative radiotherapy, and twelve patients were treated with postoperative radiotherapy. RESULTS: Twenty patients were eligible for response evaluation. Response rate was 55% (11/20). The 5-year disease free survival was 42.2% and 5-year overall survival was 46.2%, respectively. Fifty percent (12/24) experienced with acute skin complications of grade III or more during radiotherapy. Late complications were found in 8 patients. 50% (6/12) of patients treated with lymph node dissection experienced severe late complications. One patient died of sepsis from lymphedema. However, only 16.6% (2/12) of patients treated with primary radiotherapy developed late complications. CONCLUSION: Outcome of patients with vulvar cancer treated with radiotherapy showed relatively good local control and low recurrence. Severe late toxicities remained higher in patients treated with both node dissection and radiotherapy.

The congenital cataract is the relatively common cause of the blindness in childhood, and its etiology is multiple but most of etiology is unknown. The inheritance is the largest single category of cause of congenital cataract. The modes of the inheritance are autosomal dominant, autosomal recessive and X-linked. The autosomal dominant inheritance is the most common type. We experienced hereditary congenital cataract, which transmitted with autosomal dominant inheritance. So we reported this patients with review of literatures.
