Acetabular erosion, intrusion of the prosthesis into the pelvis, is the most serious late complication of hemiarthroplasty. For the detailed observation on this lesion, the authors reviewed 55 patients who underwent femoral head replacement and were followed up to at least 1 year after operation. The acetabular erosion were present in 18 patients(32.7%) out of the total 55 patients. Based on the results of this study, the authors presented a new classification of acetabular eorsion: Stage I(erosion of the cartilage only) was seen in 11 patients, stage II (evidence of the initial bony erosion) in 4 patients,and stage III(intraosseous intrusion of the metallic head) in 3 patients. Revision arthroplasty was obligatory in two of the three stage III patients. The severity of symptoms did not always correspond with the radiological changes. The acetabular erosion was more common in younger patients, in male patients and in patients with avascular necrosis of femoral head than in older patients, in female patients, and in patients with femoral neck fracture. The tendency of acetabular erosion occurring mainly in younger and male patients is probably attributed to their better survival and greater activity.

BACKGROUNDS: An inhibitory effect of magnesium L-ascorbyl-2-phosphate (VC-PMG, a stable derivative of ascorbic acid) on melanogenesis has been described. Furthermore, glabridin in licorice is known to have inhibitory effects on melanogenesis and widely used for raw materials for depigmenting agents. OBJECTIVE: The purposes of this study are to provide objective data by measuring the visual clinical effects of VC-PMG with the colorimeter and to promote the development of de-pigmenting agents. METHODS: 20 volunteers joined the study. With an artificial UVB irradiation, eight tanned areas were made on the inner side of the forearm. During two months, each tanned area was treated with five whitening cosmetics with 3% VC-PMG and increasing concentration of licorice from 0% to 3%. Darkness degree of each area was measured weekly by the colorimeter and the visual assessment. RESULTS: For all cosmetics, whitening effect was measured by colorimeter and visual as-sessment. The cosmetic containing VC-PMG 3% and licorice 1% had more whitening effect than any other cosmetics of different concentrations. Moreover, VC-PMG 3% alone also had whitening effect in some volunteers. CONCLUSION: VC-PMG was clinically found to have whitening effect.

Castleman's disease(Giant lymph node hyperplasia) is a pathologic entity of unknown etilogy, as attested to bythe number of names it has received, lymphoid hamartoma, angiomatous hamartoma, and giant lymph node, etc.Although the mediastinum is its most common location, it also occures in other areas of the body, usually wherelymph nodes are normally found. Authors have been experienced 2 cases of histologically porven Castleman's diseaseduring recent 3 years in Kyung Hee University Hospital, and present its radiological and pathological findings asmediastinal mass.

Total anomalous pulmonary venous return(connection) is a congenital heart disease. Especially, the reports of the patients with double connections of all pulmonary veins were rare. An infant who underwent operation for total anomalous pulmonary venous return had double drainge of all pulmonary veins to both left vertical vein and anomalous descending vein. This second lesion was not diagnosed preoperatively, but in operative field. Operative treatments were performed by ligation of left vertical vein and central pulmonary vein-to-left atrium anastomosis without ligation of the descending anomalous vein. For these less common variants fo total anomalous pulmonary venous return,a more detailed and precise understanding of morphology can facilitate accurate surgical repair. And also, early detection of the disease is an another issue for a good prognosis.

There has been few papers regarding the pathologic changes of kidney induced by contrast media, especially in terms of iodine concentration or osmolarity. In order to evaluate histopathologic changes, a series of rat kidneys, after injection of iodinated contrast media, were examined. A total of 220 rats were divided into two groups: those given Urografin-60% by 6.3 ml/Kg(1840mg/6.3ml):those given Urografin-76% by 5ml/Kg(1850mg/5ml). (the same amount of iodine but at different iodine concentration). The kidneys were removed and microscopically examined on 1, 2, 3, 5, 7, 10th days, 2nd, 3rd, 4th, 6th and 12th weeks after injection of contrast media, respectively. The results were as follows: Renal pathologic changes induced by contrast media were congestion and ectatic change of the interstitial vessels, epithelial degeneration and necrosis of the collectiong ducts. Congestion of interstitial vessels and epithelial degeneration and necrosis of the collecting ducts were severe in the higher iodine concentration Urografin-76% group(2100 Osm/Kg H2O) than the Urografin-60% group(1500 Osm/Kg H2O). And above pathological changes persisted for 12weeks without significant interval changes. The authors conclude that the renal damage induced by ionic contrast media becomes more severe in higher concentrations or osmolarities in spite of the same amount of iodine and that the pathologic changes persisted until 12 weeks without improvement.
