Mycosis fungoides(MF) is a cutaneous T-cell lymphoma of low-grade malignancy characterized by the proliferation of small to medium-sized cerebriform lymphoid cells confined to the skin. It usually shows favorable prognosis, but morphologic transformation occurs in some cases and is often associated with a more aggressive clinical course. Herein we report a case of Ki-1 positive large cell lyrnphoma (Ki-1 LCL) which developed in the plaque stage of mycosis fungoides. Although the lesions responded well to low-dose methotrexate therapy and there was no evidence of local or systemic recurrence until now, continuous follow-up is needed because the prognosis of transformed MF is known to be poor compared with primary cutaneous Ki-1 LCL. We also discussed the differential diagnosis of primary cutaneous Ki-1 positive lymphoproliferative disorders.

Double contrast arthrography has been widely accepted as a method to diagnose the internal derangement of the knee. It is a safe and technically simple procedure permitting accurate diagnosis of lesions of the menisci. In 20 cases operated upon, with the diagnosis of internal derangement of the knee, we performed double contrast arthrography before surgery. We analysed the cases concerning the diagnostic accuracy of arthrography, its clinical significance and discrepancies between arthrographic findings and postoperative lesions. The results were as follows: 1. The cases consisted of 16 cases of meniscal lesion, 4 cases of ligamentous lesion and 3 cases of loose body. 2. In the meniscal lesions, 14 of the 16 cases (87.5%) were diagnosed accurately by arthrography, Therefore arthrography was more useful in diagnosing meniscal lesions as compared with clincal symptoms (69%). 3. In cases of ligamentous lesions arthrography was not significant-ly helfpful, in contrast clinical signs afforded important clues. 4. We encountered 1 case of false positive and 1 case of false negative.

To evaluate the cardiac functions we examed the M-mode echocardiography with measurements of blood pressure, heart rate and body surface area in 55 normal Korean adults(male 30 persons, female 25 persons) of mean age, 41.7+/-12.3 years. (1) Interventricular septal thickness is 9.5+/-1.7mm and left ventricular posterior wall thickness are 8.6+/-1.5mm at end-diatole, 14.0+/-2.1mm at end-systole. (2) Diastolic and systolic left ventricular internal dimensions are 49.1+/-4.8mm and 31.3+/-5.0mm, respectively. (3) Left ventricular mass by Penn Convention method is 174.4+/-52.1g and left ventricular mass index is 103.2+/-28.8g/m2. (4) Relative wall thickness is 0.35+/-0.06. (5) Left ventricular volumes by Teichholz's method are 114.9+/-27.6ml at diastole and 40.2+/-17.2ml at systole. Therefore, stroke volume is 74.7+/-16.9ml and stroke volume index is 44.5+/-10.7 ml/m2. (6) Cardiac output is 4944+/-1058 ml/min and cardiac index is 2951+/-666 ml/min/m2. (7) Total peripheral resistance is 1454+/-356 dynes-sec-cm(-5) and total peripheral resistance index is 2472+/-623 dynes-sec-cm(-5).m2. (8) Fractional shortening is 36.5+/-6.0% and pressure-volume ratio is 3.27+/-1.19 mmHg/ml. (9) End-systolic wall stress is 61.3+/-19.7x10(3) dynes=cm2. (10) Atrial emptying index is 0.66+/-0.18.

This study was done to present a criterion in selection of the most proper light sources and materials by measuring metamerism index(MI) of the light curing composite resins with spectrocolorimeter. Metamerism is defined when two objects appear to be the same color in one illuminant but different in another. This is due to the fact that they have different spectral curves that fail to match under the second illuminant. In this study, A1 & A3 shade of five light curing composite resins (Esthet-X, Filteck Z250, Filteck A110, Charisma, Vitalescence) were chosen based on Vita shade. Five samples were made for shade of each product with Teflon mold (diameter: 15mm, thickness: 2mm). Metamerism index of each samples on a Barium sulfate plate (L*=96.54, a*=0.19, b*=0.01) prepared for sample fixation were measured with spectrocolorimeter(Miniscan XE plus, Model 4000s, Hunter Lab, USA) by applying standard light source D65, C, Fcw, TL84 and A. Standardization was done with reference standard (X=80.8, Y=85.7, Z=90.8) and light trap. The results were as follows. 1. Different resins with same Vita shade showed recognizable color difference(DeltaE*>2). 2. All composites had MI below accepted value 0.5 between standard illuminant(D65, C, & A) and below 1.5 under fluorescent condition (Fcw & TL84). 3. MI value between D65 and A showed higher value than MI value between other source of light(p<0.01). 4. All resins except Z250 showed MI value that A3 is higher than A1 between D65 and A(p<0.05).

STUDY DESIGN: Retrospective study. OBJECTIVES: To conduct an analysis of the union rate and union patterns of local autogenous bone grafts using metal cages, allogenic bone, and local autogenous bone around the cages in posterior lumbar interbody fusion (PLIF). SUMMARY OF LITERATURE REVIEW: Local autologous bone grafting using metal cages is regarded as an effective method for union during PLIF without iliac bone harvesting. There are few studies about the additional bone grafting except using metal cages. MATERIALS AND METHODS: Thirty-nine patients (68 segments) with postoperative computed tomography (CT) results from 6 to 18 months after PLIF were included. We used 2 metal cages filled with local autogenous bone intraoperatively (region C). We also grafted allogenic bone between 2 cages (region A) and local autogenous bone at the side of the cages (region B). Retrospective analyses of the coronal CT sections were performed using the modified Bridwell criteria for assessing the presence of union. A quantitative evaluation was performed using a scoring system that assessed the proportion of radiopaque parts of the union mass. RESULTS: Among the 68 segments, union was observed in 64 segments, resulting in a union rate of 95.6%. The union rates in regions A, B, and C were 86.8%, 89.7%, and 94.1%, respectively. Trabeculation and the quantitative evaluation of union bone showed a statistically significant trend for improvement from regions A to C (p<0.001). CONCLUSIONS: In this study, the complementary effect of additional bone grafting other than local bone grafting was not proven, but it was effective in increasing the fusion area at around 90%. Keeping the height of disc space with the cages, additional bone grafting using local autogenous and allogenous bone may be used as an effective method for stable union.

Fifty-four adenocarcinomas of stomach were investigated to assess the expression of p21 and p53 using an immunohistochemical method. The relationship between p21 and p53 expression and the clinicopathologic parameters were analysed. The staining pattern of p21/p53 were: p21+/p53+, p21-/p53+, p21+/p53-, and p21-/p53- in 30, 12, 8, and 4 cases, respectively. Loss of p21 expression was observed in 16 of 54 tumor tissues (29%). p21 expression, however, had an inverse correlation with vascular invasion and depth of tumor invasion. The p21 and p53 protein expression showed intratumoral heterogeneity. In 63% of the adenocarcinoma, a proportional relationship was found between p21 and p53 immunostaining. The present results suggest that p53 independent induction of p21 expression may be involved in the molecular mechanism of these tumors, and expression of p21 protein may be related to a favorable prognosis in gastric adenocarcinomas.
