The authors reviewed both the clinical and radiographic results of 36 bipolar hemiarthroplasty using the porous-coated Harris-Galante uncemented femoral stem performed for avascular necrosis in 30 patients from January 1985 to June 1992. The average age was about 45.6 years and the average follow-up was fifty-four months. Clinical results by the Harris evaluation method were excellent in 33 cases, good in 2 cases, and fair in 1 case. The radiographic fixation of the femoral stem at final follow-up was bony ingrowth fixation in 31 cases, fibrous ingrowth fixation in 4 cases, and unstable fixation in 1 case. There was neither medial nor superior migration of the bipolar cup of more than two millimeters.

Terrys nail(TN) might be causally associated with cirrhosis or other disorders, but his criteria have been proved to be inadequate reflection of systcmic disorders. Modified criteria of Holzberg and Walker were introduced in TN examination in 1984. Using these criteria, fingernails were studied in 444 medical inpatients with chronic systemic diseases at Taegu Catholic Hospital from March 1991 to March 1992. There were 136(30.6%) patients with TN and 308(69.4%) patients without TN, respectively. Ninety-three patients with TN showed a signifiart association with cirrosis(49/86, 57%, p<0.01 by the x-test), congestive heart failure 18/35, 515, p<0.05), and diabetes mellitus(25/51, 49%, p<0.05), and otherwise not;ignificantly associated with chronic renal failure(19%), and cancer(18%). Male and female patients with TN were affected about equally. Age distribution in The patients with TN showed 35(25.8%) the age group from twenty to fortynine and 101(74.2%) in the age group from fifty and above with a mean age of 57.3+14.0, whereas the patients without TN had 178(57.8%), and 130(42.2%), with 47.4+16.9, respectively. The greater part was distributed in the older group(p<0.001 by student t-test), suggestive of an increased risk in older group. The average number of nails affected per patient was tending to be higher in frequency close to the thumb, with an equal frequency in six. Thirty-nine patients(28.7%) had all nails affected. The distal band with was 0.5 to 3.0mm averaging 1.0+0.5mm with no difference, in sex. The distal band was pink in 43(31.6%) of the 136 patients with TN, brown in 62(45.6%) and intermediate in color in 13(22,8%). The results of routine laboratory test such as hemogram, eiythrocyte sedimenation rate, liver enzyme, triglyceride, protein, albumin, blood urea nitrogen and creatinine were statistically insignificant between the patients with and without TN.

Thirteen guinea pigs and 23 rabbits were challenged with 300 metacercariae of Clonorchis sinensis each and the recovery of adult worms and egg counts in feces were compared at 11-13 weeks post-infection in guinea pigs and at 7-9 weeks post-infection in rabbits. The recovery rate of adult worm was 23.5 percent in guinea pigs and 20.l-30.5 percent in rabbits. The mean E.P.G. of these animals in above period of infection was 106 in guinea pigs and 121 in rabbits. When one hundredth of E.P.G. was expressed as X and the number of adult worms as Y, the relationships between X and Y were as follows; Y=0.8X+10.8 in guinea pigs and Y=0.7X+6 in rabbits.

We report herein a case of lymphomatoid papulosis in a 23-year-old female who had recurrent erythematous pinhead to pea sized papules and nodules on the both inner thighs and forearms for 4 years. Some lesions showed central hemorrhagic necrosis or scale formation. Individual lesions persisted for several months and showed spontaneous regression leaving pigmentation or depigmented atrophic scar. Histopathologically, there was marked cell infiltration, especially in the dermoepiderrnal junction and perivascular area. Infiltraled cells consisted of sorne ncutrophils and numerous atypical cells that had variable sized and irregular shaped nuclei. Electronmicroscopically, some atypical cells had cerebriform nuclei with marked peripheral condensation of chromatin and cytoplasm contained a few organelles, many polyribosomes and some dense bodies.

Wilson disease gene (WND) locus is presumed to be located in chromosome 13q. There are studies on the clinical heterogeneities and variations between ethnic groups in Europe, North America, and the Middle East and it requires the study of another ethnic group, especially Asian population for the confirmation. This study was an anlysis of restriction fragment length polymorphism of the Wilson's disease with the probes on D13S26, D13S31, and D13S59, The subject was 34 persons of seven families. The serum ceruloplasmin and the serum copper were also measured. The results were as follows: 1) The Wilson disease gene was also presumed to be located in chromosome 13q area in Korean patients and D13S25, D13S26, D13S31 and D13S59 gene loci were also linked to Wilson disease of Koreans. The lod score of D13S25 was 1.45 (theta =0: D13S59, 1.13 (theta =0): D13S26, 247 (theta =0). 2) Three siblings of Wilson disease patients were diagnosed as carriers by the analysis of restriction fragment length polymorphism. 3) In Wilson disease patients, the serum ceruloplasmin and copper was 6.8+/1.8dl, and 64.7+/-38.6microg/dl respectively and it is 18.8+/-6.1 mg/dl and 65.3+/-10.6microg/dl respectively in heterozygotes.

The purpose of this study was to investigate the gaps of bone-acetabular component interface, the initial mechanical stability and the effects of adjuvant screw fixation in the press-fitted two different shaped porous-coated acetabular components. Semi-hemispherical Harris-Galante II cup and full hemispherical Trilogy cup were press-fitted with or without adjuvant screw fixation in 40 bovine femur. The gaps of bone-implant interface were measured in each radiography of all specimen and axial compression tests and rotational stability tests were performed using servohydraulic tension-compression machine. There was significantly smaller gap at polar 1/3 region in the specimen implanted with Trilogy cup. But the adjuvant screw fixation did not affect the amount of gap. There was no significant statistical difference in axial load and rotational stability test in each situations of fixation. This study demonstrates that the initial mechanical stability is not influenced by the shape of semi-hemispherical Harris-Galante II cup and full hemispherical Trilogy cup and also independent of adjuvant screw fixation. But smaller gap of Trilogy cup at the polar 1/3 region indicates the possibility that less amout of wear debris of polyethylene or metal will be deposited and therefore less osteolysis or cup loosening will occur, but this hypothesis should be confirmed by the long-term clinical follow-up.

We studied the natural history of asymptomatic early avascular necrosis of the femoral head in forty-three patients(forty-three hips) who had been treated with arthroplasty due to progressed avascular necrosis of femoral head but had no symptoms in the other side. All initial lesions were classified with Ficat staging and International classification(ARCO). The duration until symptom onset and radiologic evidence of disease progression were evaluated. The average follow up period was over 37 months. Among forty-three hips, twenty-nine cases(67.4%) remained asymptomatic until last follow up but fourteen cases(32.6%) were symptomatic during the follow up, and twenty-six cases(60.5%) did not progress on the radiography but seventeen cases(39.5%) progressed to Ficat stage 3 or 4. Fifteen cases of IA, IIA, IB-cental and II B-central without lateral lesion did not occur symptom and didnt progress to Ficat stage 3 or 4 over a period of average 47 months(24-71 months). But fourteen cases of IB, IC, g B and II C progressed to Ficat stage 3 or 4 and they were all lateral lesion. These results suggest careful observation only can be done in the case of small involvement(less than 15%) and medial or central lesion relatively over a long period of time but for the large involvement(more than 30%) and especially lateral lesion, aggressive surgical treatment may be considered even though the early stage of disease for the prevention of progression. However it will need more period of time to accurately compare the results of various methods of treatment.
