Fascioliasis has not been confirmed as a human disease entity until now in Korea despite of sporadic discovery of ova of Fasciola sp. in human fecal materials being never traced to the confirmation of infection. Almost all of the cases with ova in their stool have been related with consumption of cattle liver whether eaten in raw or processed. The present authors confirmed a human fascioliasis case who was a Korean housewife of 42-year-old living in Seoul, during the exploratory laparotomy. The patient had been healthy until October 1975 when abrupt onset of urticaria, dyspepsia, epigastric discomfort developed. And the fluctuation of these symptoms was followed by epigastric colicky pain attacks from December 4, 1975. A complete worm of Fasciola sp. was removed during the bile-duct exploration with stone forceps in lower half of common bile duct, on January 20, 1976. The patient only agreed that she had eaten some raw liver of cattle on September 1975 but denied any possible sources of infection such as drinking of untreated water, handling of water flower and grass, and eating of raw watercress. The measurements of the removed worm: 35. 61 mm in body length, 14.00 mm in maximum body width(Length/width ratio, 2.54:1), distribution of testes to body length 33.9 per cent , number of branches of ovary 22, the size of intrauterine ova 157.2 x 108. 4 micrometer in average. These findings are not compatible with the classical descriptions of both Fasciola hepatica and F. gigantica, and it was concluded it is so-called Fasciola sp. which is intermediate between two species as proposed by many Japanese workers.

PURPOSE: The purpose of this study is to compare the frequency with which pseudole-sions around the gallbladder (GB) fossa are revealed by multiphasic CT, by CT during arterial portography (CTAP), and by CT during hepatic arteriography (CTHA) and to determine their radiological characteristics. MATERIALS AND METHODS:Multiphasic CT, CTAP, and CTHA examinations of 81 patients without pathology of the GB and around the GB fossa were evaluated for pseudolesion around the GB fossa. The definition of pseudolesion was as follows: 1) hyperattenuation during the arterial phase and isoattenuation during the delayed phase of multipha-sic CT, or perfusion defect on CTAP and hyperattenuation on CTHA; 2) no Lipiodol tagging on Lipiodol CT; 3) all findings observed adjacent to the gallbladder fossa; and 4) no interval change on follow-up CTAP and CTHA. We compared the frequency of pseudolesions around the GB fossa, as seen on multiphasic CT, CTAP, and CTHA, and determined their size, location, and shape, as revealed by CTHA. RESULTS: The frequency of pseudolesion was 2.5% (2/81) on multiphasic CT, while on CTAP or CTHA, the frequency was 53.1% (43/81), and 58 pseudolesions were identi-fied. Of 58 pseudolesions, 56 were revealed by CTAP and 57 by CTHA. Forty-nine of 58 pseudolesions were larger and all pseudolesions showed more contrast to parenchyma on CTHA than on CTAP. The location of pseudolesions was segment V(32 of 58), IV (25 of 58), and VI (1 of 58), and their size ranged from 5 to 30 (mean, 17.5)mm. Pseudolesions were wedge-shaped (48 of 58), oval (6 of 58), bandlike (3 of 58), or round (1 of 58). CONCLUSION: CTAP and CTHA frequently revealed pseudolesion around the GB fossa. The radiological characteristics of these modalities help differentiate pseudolesions from true tumoral hepatic lesions.

PURPOSE: The purpose of this study is to show the total survival rate of implants with maxillary sinus floor elevation and the effects that reach the survival rate by classifying types of graft materials, implant surface, operation method, bone height. METHODS: In a total of 131 patients, 251 implants with sinus floor elevation were installed simultaneously or after regular healing. Various bone grafts (autograft, xonograft, allograft, alloplast) and implant surface (MTX-HA implant, chemical etching implant, Titanium oxide surface implant, resorbable blasting media implant, resorbable blast texturing implant, HA-coated implant) were used. All implants were investigated clinically and radiographically, being with 1 to 5 years follow-up period after installation. RESULTS: The survival rate of 251 implants with maxillary sinus floor elevation was 94%. The types of implant, surface, graft material, bone height have no statistically signi-ficant differencies. CONCLUSIONS: It can be suggested that maxillary sinus floor elevation may have predictable result with various bone graft materials and implant surface.

PURPOSE: The purpose of this study was to evaluate 2 years cumulative survival rate of implants on augmented sinus area using MBCP, mixture of MBCP and ICB, and mixture of MBCP and autogenous bone by means of clinical and radiologic methods. MATERIALS AND METHODS: In a total of 37 patients, 41 maxillary sinuses were augmented and 89 implant fixtures were installed simultaneously or after a regular healing period. The patients were divided in 3 groups: MBCP only, MBCP combined with ICB, MBCP combined with autogenous bone. After delivery of prosthesis, along 2 years of observation period, all implants were evaluated clinically and radiologically. And the results were as follows. RESULTS: The results of this study were as follows. 1. A 2 year cumulative survival rate of implants placed with sinus augmentation procedure using MBCP was 97.75%. 2. Survival rate of implants using MBCP only was 97.62%, MBCP and ICB was 100%, MBCP and autogenous bone was 95%. There was no statistically significant difference between 3 groups. 3. Only 2 of 89 implants were lost before delivery of prosthesis, so it can be regarded as an early failure. And both were successfully restored by wider implants. CONCLUSION: It can be suggested that MBCP may have predictable result when used as a grafting material of sinus floor augmentation whether combined with other graft(ICB, autogenous bone) or not. And the diameter, length, location of implants did not have a significant effect on 2 year cumulative survival rate.

The role of the donor and recipient gender have been a controversial point in the outcome of renal transplantation and the pathophysiologic mechanisms are not understood clearly. In order to evaluate the effect of gender on the renal graft survival, we reviewed our 400 consecutive living donor renal transplantation. The patients were divided into four groups, Group 1; male donor and male recipient(n=152), Group 2; female donor and male recipient(n=61), Group 3; male donor and female recipient(n=135), and Group 4; female donor and female recipient(n=52). To estimate the transplant outcome between the groups, we analyzed patient and graft survival, acute tubular necrosis, BUN, creatinine and rejection episode for maximum 5 years after transplantation. The level of BUN(34.7+/- 26.4, 19.8+/- 6.4, 30.5+/- 14.6, 23.1+/- 10.5 in group 1,2,3,4 respectively) and serum creatinine(2.62+/- 2.3, 1.48+/- 1.1, 2.24+/- 1.2, 1.65+/- 0.9 in group 1,2,3,4 respectively) were higher in male recipient groups regardless of donor gender. However, donor and recipient gender had no influence on post-graft blood pressure and acute tubular necrosis(p>0.05). Acute rejection episode was predominent at female donor graft than male donor graft(36.4% vs 30.1%). The 5 year graft survival in group 1,2,3,4 were 67.8, 67.2, 60.1, 72.7% and patient survival were 76.9, 75.6, 72.6, 80.5% in their orders. These results suggest that donor and recipient gender might play a role in the outcome of renal transplantation. The mechanism of these results must be analyzed by further evaluation using larger patient group.
