The incidence, type arid distribution of polyneuropathy in patients with chronic obstructive pulmonary disease (COPD) were assessed and also analyzed the causative factors. Forty-four patients, mean age 66.1 years (42 male, 2 female), have been investigated with arterial gas analysis, pulmonary function test, clinical and electrodiagnostic studies. None of them had conditions known to affect the peripheral nervous system such as metabolic disorders or drugs. In a selected group of 44 patients, electrophysiological findings of polyneuropathy were found in 22 patients(50%), clinical polyneurtpathy were diagnosed in 13 patients(9 patients were diagnosed by electrophysiological studies, 4 patients were normal by electrophysiological studies). These findings indicate that subclinical polyneuropathy( 13 patisnts, 30%) more conimorily occurs than clinical polyneuropathy( 9 patients, 20%) in associated with COPD. In the patients with polyneuropathy, the lesions were predominant axonal degeneration, the changes were more involved in leg than arm, more frequently affected sensory fibers. We could not find etiologic factor to cause polyneuropathy in COPD patients.

An aortic aneurysm is described as a permanent localized dilatation of the aorta having a diameter at least 1.5 times that of the expected norrnal diameter of that given aortic segment. Thoracic aortic aneurysms are much less common than are aneurysms of the abdominal aorta. Thoracic aneurysms are classified by the portion of aorta involved, I.e., the ascending, arch, or descending thoracic aorta. We experienced a case of saccular arteriosclerotic aortic aneurysm associated with thrombus in aortic arch in a 78 year-old male who had history of hypertension. He was admitted to Kwangju Veterans Hospital complaining of drowsy mental state and swelling of left foreann. The chest X-ray, chest CT and echocardiogram showed saccular dilatation(maximal diarneter ; 7.67~7.86cm) associated with thrombus in aortic arch. He refused operation because of old age, so he was conservatively rnanaged including propranolol. We report this case of saccular arteriosclerotic aneurysm of aortic arch with a brief review of literature.

BACKGROUND: Cathepsin D, an aspartic lysosomal proteinase, is believed to be involved in local invasion and metastasis of tumor cells by its proteolytic activity and has been described to be associated with tumor progression and prognosis in some human malignancies including breast cancer. But, its prognostic value for human lung cancer remains to be determined. The purpose of this study is to determine clinicopathological and prognostic significance of cathepsin D expression in non-small cell lung cancer. METHOD: Using a polyclonal antibody, immunohistochemical analysis of cathepsin D was performed on paraffin embedded sections of tumors obtained surgically from 54 patients with non-small cell lung cancer (37 squamous cell carcinoma, 14 adenocarcinoma, 2 large cell carcinoma, and 1 undifferentiated carcinoma). RESULTS: Eighteen patients (33.3%) showed positive immunoreactivities of cathepsin D in tumor cells. No significant correlation of cathepsin D expression in tumor cells was found in p-stage (surgical-pathologic stage), tumor size, tumor factor, nodal involvement, and differentiation. Of 54 patients, 29 (53.7%) patients showed moderate to massive cathepsin D-positive stromal cells within the tumor tissues, while the rest (46.3%) showed few cathepsin D-positive stromal cells within the tumor tissues. Cathepsin D expression n stromal cells was significantly associated with p-stage in non-small cell lung cancer (p=0.031). No significant correlation of the degree of cathepsin D-positive stromal cells was found in tumor size, T-factor, nodal involvement, differentiation. Cathepsin D expression status in tumor cells and stromal cells was not significantly associated with prognosis expressed by survival rate. The results of multivariate analyses of variables possibly associated with progonosis showed that nodal involvement was the only independent prognostic factor in all patients. CONCLUSION: Cathepsin D expression in stromal cells was significantly associated with p-stage in non-small cell lung cancer. However, it was not related to other clinicopathologic features and prognosis, and Cathepsin D expression in tumor was not related to p-stage and prognosis.
