Friction melanosis is frequently developed in thin, young woman, on thc covered skin of spinc, rib, elbow, knee and tibia. These lesions range from brown to rcddish-brown in color, appear in either band shapes or reticular patterns, and exhibit no overt syrnptoms. They do not show any inflamatory changes, and the skin remains smooth. According to histopathological findings, the main changcs arc perivascular melanophages on the papillary derrnis and upper dermis, and also increased melanin granules on the basal layer. The following case concern a relatively thin 20-year-o1d female patient. She had a syrwptoniless brown color changcs above the ribs of back, growing in dircction of the ribs for a period of three years. This change was band shaped, but there were no signs of inflammatory reaction, leaving the skin smooth. A biopsy was performed on the relevant tissue, and clinical-histopathological analysis was resulting in diagnosis of friction melanosis.

Cervical tuberculous lymphadenitis is a commonly encountered disease, expecially in adults, Differentiation from other lymphadenopathy and benign conditions such as cystic neck masses is important. CT findings of tuberculous lymphadenopathy in the abdomen and thorax are reported in many literatures. But there are only a few articles concerning cervical tuberculous lymphadenopathy. The authors retrospectively analyzed CT findings of 33 cases with cervical tuberculous lymphadenitis regarding distribution, contour, enhancing pattern, changes of adjacent fascial plane, and dermal and subcutaneous manifestations. We concluded that the presence of conglomerated nodal masses with central lucency, thick irregular rim of contrast enhancement and inner nodularity, varying degree of homogenous enhancement in smaller nodes, dermal and subcutaneous manifestations of inflammation such as thickening of overlying skin, engorgement of the lymphatic and thickening of adjacent muscles, and diffusely effaced fascial plane are suggestive of tuberculous lymphadenitis. However, some CT patterns of tuberculous adenitis may be seen in other disease; for example, enhancement can occur in hyperplastic nodes, vascular metastasis(thyroid, melanoma, and hypernephroma), lymphoma, granulomatous disease, and Castleman's disease.

We report a caae of hepatic and intestinal infestation with paragonimus wewstermani complicating abscess formation. The pathway by which the paragonimus westermani reaehea liver and intestine is not well understood. However, there was possiblity that it may become lodged in other organs that the lung because of polonged larval migrations through the diaphragm or into various sites in the abdomen. The patient, 52-year-old female gave a history of having reyeatedly consumed raw crabs. An x-ray film of the chest showed clear lunga Skin test for paragonimus-westermani was positive. Abdominal ultrasonogram showed enlargement of the liver with multiple hypoechoic lesiona ERCP revealed multiple ie lesions in the right lobe of the liver. Abdaminal CT showed multifocal abscess cavities with slight rim enhancements. Above meetioned diagnostic procedures suggested liver abscess or hepatoma. Then, an exploratory laparotomy was done for a definite diagnosis, Frozen biopsy, from liver and surgically exe mass from ileocecal region revealed extrpulmonary paragnomiasis involving liver and cecum. Thus, the patient was treated with prasiquantel. Three months later, abdominal ultrasonogram demonstrated slight enlargement of the liver but no evidence of abnormal mass like lesions.

In order to search for anti-Herpes simplex virus (HSV) type-1 agents from Korean medicinal herbs and Korean traditional prescriptions (herb complexes), we selected 80 medicinal herbs and 45 prescriptions, based on a review of the Korean traditional medicine books. Both methanol extracts and boiling-water extracts were tested by means of the MTT assay (tetrazolium based colorimetric assay). Ten of the 125 methanol extracts: CM-11, CM-18, CM-19, CM-21, CM-22, CM-39, MM-3, MM-18, MM-29, MM-73 (see explanation of nomenclature below), showed efficacy against HSV-1. Twelve of the water extracts: CW-2, CW-3-I, CW-3-II, CW-18, MW-3, MW-5 MW-6, MW-12, MW-47, MW-69, MW-73 and MW-75 were active. #3 (individual herb) and #73 (individual herb) were interesting because both water and methanol extracts were active. Especially, #3 is a part of composition of Hong-il-laksamd ngbang and Hojanghaedokt'ang which have anti-HSV-1 activitives. The SI value of MW-69 and CW-18 was relative high as 10.2+/-0.7 and 11.8+/-2.2. The cytotoxic effect on Vero cells of Panch' n-ch' ngbang, Taraxacum platycarpum H. Dahlst. and acycloguanosine was determined by MTT assay. Water extracts of Panch' ngch' ngbang (prescription) and Taraxacum platycarpum H. Dahlst. showed very weak cytotoxic effects on Vero cells at > 100 mug/ml but acycloguanosine showed strong cytotoxic effects on Vero cells at > 100 mu g/ml. As a result, #3, #73, MW-69 and CW-18 are considered as potentially useful for anti-HSV-1 agent and will be the focus of further research. Abbreviations: CM - methanol extracts of traditional prescriptions; CW - water extracts of traditional prescriptions; MM - methanol extracts of individual herbs; MW - water extracts of individual herbs.

The development of a safe method of transfer of the greater toe for thumb reconstruction, using dorsalis pedis artery and the great saphenous vein, suggested the possibility of one stage microvascular transfer of the second toe for reconstruction of surgery. Based upon our part experience with microsurgical experiments, limb transplantation and toe-to-thumb transplantation since 1975, we accomplished the second toe-to-index transplantation done in Korea on October 24, 1979, and succeeded in one stage second toe-to-index transplantation in two cases. Following results were obtained. I. Free second toe-to index transplantation on making a index is the most excellent method of index reconstruction with results in minimum functional and cosmetic impairment. 2. Technically, skin incision, isolation of blood vessels and flexor tendon in preparation for transplantation of second toe is more difficult than that of greater toe. 3. The specialized microsurgical training with skillful technique is essential for success.

The femoral fracture, occurred associated with the cemented hip arthroplasty, is well-known cornplication but the proximal femoral fractures of the noncemented hip arthroplasty, were occurred more than those. Among the 290 patients, who were treated by the noncemented hip arthroplasty from Dec. 1987 to April 1992, the 24 cases of the femoral fracture were experienced and the results were as follows: 1) of the 24 cases, the male was nine and the female was fifteen. The age distribution was mostly occurred between 41 and 60 years old and most fracture were developed in 1 1mm stem size. In revision cases, 225mm stem length (Wagner) was common. The locations of fracture were proximal 1/3 (type I: 19 cases), tip (type II; 1 case), distal 1/3 (type III; 1 case) and comminuted (type IV; 3 cases) by Johansson; siclassification. 2) The femoral fracture was mostly developed during the stem insertion and the fracture site in anatomical stem was only proximal femur. 3) 1n cases of revision, most of the fractures were occured on the anterior or lateral side of the femur. It was difficult to manage the fracture because of the severe osteoporosis and comminution. 4) As the problem of the operative technique, the fracture incidence can be decreased by accurate preoperative measurement and it must be cautious in the stem more than 225 mm length, which were used in revision case. 5) The circumferential wiring for proximal and plate & screws in middle and distal were done as the treatment of fracture and the results were all good, but stem tip fracture in osteoporotic patients was troublesome. We think that long plate(>8 holes) & both cortex purchase and bone graft are best methods so far.

PURPOSE: This study was conducted to know the applications and limitations of three dimensional volume rendering virtual endoscopy of the ossicles using a multi-row detector CT. MATERIALS AND METHODS: This study examined 25 patients who underwent temporal bone CT using a 16-row detector CT as a result of hearing problems or trauma. The axial CT scan of the temporal bone was performed with a 0.6 mm collimation, and a reconstruction was carried out with a U70u Sharp of kernel value, a 1 mm thickness and 0.5-1.0 mm increments. After observing the ossicles in the axial and coronal images, virtual endoscopy was performed using a three dimensional volume rendering technique with a threshold value of -500 HU. The intra-operative otoendoscopy was performed in 12 ears, and was compared with the virtual endoscopy findings. RESULTS: Virtual endoscopy of the 29 ears without hearing problems demonstrated hypoplastic or an incomplete depiction of the stapes superstructures in 25 ears and a normal depiction in 4 ears. Virtual endoscopy of 21 ears with hearing problems demonstrated no ossicles in 1 ear, no malleus in 3 ears, a malleoincudal subluxation in 6 ears, a dysplastic incus in 5 ears, an incudostapedial subluxation in 9 ears, dysplastic stapes in 2 ears, a hypoplastic or incomplete depiction of the stapes in 16 ears and no stapes in 1 ear. In contrast to the intra-operative otoendoscopy, 8 out of 12 ears showed a hypoplastic or deformed stapes in the virtual endoscopy. CONCLUSION: Volume rendering virtual endoscopy using a multi-row detector CT is an excellent method for evaluation the ossicles in three dimension, even though the partial volume effect for the stapes superstructures needs to be considered.
