Cyclin D1 overexpression is remarkably frequent in several human carcinomas and is believed to be a critical event in oncogenesis. We examined cyclin D1 expression, p53 expression, and the Ki-67 labeling index by immunostaining in human gallbladder mucosa in conditions varying from normal to malignant tissue. We also examined K-ras codon 12 mutations in(More)
Two-dimensional polyacrylamide gel electrophoresis combined with a non-enzymatic sample preparation technique is useful for analysing clinical tumour material. Using these techniques, we analysed the relationship between the histopathological findings in primary lung malignancies and the expression of a number of unidentified polypeptides that were detected(More)
The performance of the Lung Imaging Fluorescence Endoscope (LIFE) system was compared with conventional bronchoscopy in 158 patients: 68 patients with invasive cancer, 42 patients with abnormal sputum cytology findings (12 early cancer and 26 dysplasia), 17 cases with resected lung cancer and 31 smokers with symptoms. The respective results of conventional(More)
TA01 (molecular weight 35.0 kDa, isoelectric point 5.45) and TA02 (molecular weight 35.0 kDa, isoelectric point 5.29) polypeptides were detected using two-dimensional polyacrylamide gel electrophoresis (2-DE). A previous study has shown that these polypeptides are distributed in primary adenocarcinomas and some large-cell carcinomas of the lung. However,(More)
The result of the clinical trial using the lung imaging fluorescence endoscope (LIFE) was reported. A total of 77 biopsy confirmed sites from 30 patients were evaluated. The sensitivity for metaplasia detection by the LIFE system was 96% compared to 28% by conventional bronchoscopy. The LIFE system was found to be useful in detecting subtle(More)
We report a case of non-Hodgkin's lymphoma found at the orifice of right B2 accompanied by peripheral lung cancer in a 66-year-old asymptomatic man. Chest X-ray films showed a mass shadow in the left lower lung field. Transbronchial lung biopsy of left S9 demonstrated squamous cell carcinoma. Simultaneously wall thickening at the orifice of the right B2 was(More)
Respiratory papilloma is a rare lesion that arises in the larynx, trachea and bronchus. We describe a patient with laryngeal papilloma that spread to the trachea and which was effectively treated by Nd-YAG laser. Two years after the initial treatments of the laryngeal and tracheal papillomas, a recurrent lesion (solitary papilloma) was observed on the(More)
