BACKGROUND: the prediction on changes in the lung function after lung surgery would be an important indicator in terms of the operability and postoperative complications. In order to predict the postoperative FEV1 - the commonly used method for measuring changes in lung function- a comparison between the quantitative CT and the perfusion lung scan was made and proved its usefulness. MATERIAL AND METHOD: The subjects included 22 patients who received perfusion lung scan and quantitative CT preoperatively and with whom the follow-up of PFT were possibles out of the pool of patients who underwent right lobectomy or right pneumonectomy between June of 1997 and December of 1999. The FEV1 and FVC were calibrated by performing the PFT on each patient and then the predicted FEV1 and FVC were calculated after performing perfusion lung scan and quantitative CT postoperatively. The FEV1 and FVC were calibrated by performing the PFT after 1 week and after 3 momths following the surgery. RESULTS: There was a significant mutual scan and the actual postoperative FEV1 and FVC at 1 week and 3 months. The predicted FEV1 and FVC(pneumonectomy group : r=0.962 and r=0.938 lobectomy group ; r=0.921 and r=913) using quantitative CT at 1 week postoperatively showed a higher mutual relationship than that predicted by perfusion lung scan(pneumonectomy group : r=0.927 and r=0.890 lobectomy group : r=0.910 and r=0.905) The result was likewise at 3 months postoperatively(CT -pneumonectomy group : r=0.799 and r=0.882 lobectomy group : r=0.934 and r=0.932) CONCLUSION: In comparison to perfusion lung scan quantitative CT is more accurate in predicting lung function postoperatively and is cost-effective as well. Therefore it can be concluded that the quantitative CT is an effective method of replacing the perfusion lung scan in predicting lung function post-operatively. However it is noted that further comparative analysis using more data and follow-up studies of the patients is required.

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.

Transitional cell carcinoma of the urinary bladder is the most common cancer of the urinary tract and is characterized by frequent recurrence. Like the other malignant tumor, the genetic alterations leading to neoplastic transformation of the urothelium are related with the activation of oncogenes and loss of functional tumor suppressor genes. Cyclin D1 is a putative protooncogene as cell cycle regulator essential for G1 phase progression and is frequently overexpressed in several human tumor. In this study we performed immunohistochemical stainings of cyclin D1 and p53 in both primary and recurrent transitional cell carcinomas of urinary bladder from 56 patients including 20 cases of recurrent tumor, and compared their results with histopathologic features. The results were as follows. Cyclin D1 immunoreactivity was found in 10 of 10 cases (100%) of grade 1, 25 of 41 (61%) cases of grade 2, and 11 of 25 (44%) cases of grade 3 transitional cell carcinomas. p53 immunoreactivity was found in 40% of grade 1, 63% of grade 2, and 87% of grade 3 lesions. Cyclin D1 expression was significantly higher in Ta and T1 lesions than T2 to T4 by pathologic tumor stage. Conversely p53 immunoreactivity was increased in proportion to the T classification. Cyclin D1 was de creased in recurrent transitional cell carcinomas, compared with primary transitional cell carcinomas. However, there was no statistical significance. In conclusion, cyclin D1 immunoreactivity is associated with low histologic grade and low tumor stage. And there is inverse relationship between the cyclin D1 and p53 overexpression.

Based on our experience with 23 frontotemporal reconstructions performed, this paper attempts to provide guidelines for appropriate selection among the four most commonly employed materials (e.g., autogenous parietal bone, silicone rubber, methylmethacrylate, and porous polyethylene) so that optimal results can be achieved. Clinical follow-up ranged from 6 to 91 months (mean 32 months). Every patient was analyzed clinically by ordinary scale method. The mean defect size was 134.8 cm2 in the silicone rubber, 36.5 cm2 in the methylmethacrylate, 17.4 cm2 in the autogenous bone graft and 7.3 cm2 in the porous polyethylene. The clinical assessment was excellent (mean, 29.3 points) in silicone rubber, excellent (mean, 28.6 points) in autogenous bone, excellent (mean, 26.8 points) in methylmethacrylate, and good (mean, 24.8 points) in polyethylene. To sum up, a large bony defect of congenital calvarial anomaly produced an excellent result using custom-made silicone implant. A relatively small bony defect with a scarred bed produced an excellent result using autogenous parietal bone grafting. Unexpected and medium-sized defect was reconstructed successfully through a simple procedure using methylmethacrylate. Porous Polyethylene was used at an incidental small defect because of its expensiveness.
