BACKGROUND
Mucin (MUC)1 and MUC4 (MUC1, 4) are high molecular weight glycoproteins expressed in normal and malignant epithelial cells, and these expressions are related to the prognosis of some carcinomas. In non-small cell lung carcinoma (NSCLC), the relationship between MUC1, 4 expressions and their prognostic significance is not well known. We evaluated these relationships in a series of NSCLC: 1) between MUC1, 4 expression levels and histologic subtypes, and 2) between high expression of MUC1, 4 and their prognostic significance.
METHODS
We performed immunohistochemical staining for MUC1, 4 in paraffin-embedded tissues from 165 NSCLC cases arranged in a tissue microarray.
RESULTS
We found a significant correlation between MUC1, 4 expressions and NSCLC histologic subtypes (p < 0.05). High MUC1 expression was characteristic of adenocarcinoma. Low MUC1, 4 expressions were characteristic of squamous cell carcinoma. In adenocarcinoma, we found significant association between diffuse MUC1 expression and short patient survival (p = 0.005). In squamous cell carcinoma, diffuse MUC4 expression showed long patient survival trend (p = 0.128).
CONCLUSIONS
MUC1, 4 expression levels were significantly correlated with NSCLC histologic subtypes. Diffuse MUC1 expression was significantly associated with shortened survival in NSCLC patients, especially in adenocarcinoma.

Abstract PDF: Lung cancer is one of the most common types of malignancy in western nations with serious health problem, and it has become the leading cause of cancer death of males, second only to stomach cancer, in Korea. A review of the histopathology of 1363 cases (1231 patients) of lung carcinoma, diagnosed at the Keimyung University Medical center from 1987 to 1996, was performed to reclassify the type of carcinomas and to investigate the change in the distribution of histologic types of lung carcinoma according to age, sex and year. Among the 1363 cases, 132 patients underwent a surgical operation after biopsy. The diagnosis of each case was proven by histopathologic analysis of surgical specimens (13.2%) and biopsy materials (86.8%). The histologic types in our study were basically based on modified WHO classification (1982) and on new WHO classification (1999). The classification of small cell carcinoma was based on International Association for the Small Cell Lung Cancer (IASLC, 1988). Of the 1231 patients with lung carcinoma, 1012 were male and 219 were female (male to female ratio was 3.6:1). According to the analysis of age distribution, the most prevalent age group was 60~69 years in both sex as (n=516, 42.0%). Changing trends in sex distribution of lung carcinoma patients showed that the proportion of men had decreased throughout the years, whereas the proportion of women had significantly increased. Histologically, squamous cell carcinoma was the most common (n=624, 50.7%), followed by small cell carcinoma (21.1%), adenocarcinoma (18.1%), large cell undifferentiated carcinoma (2.1%), adenosquamous carcinoma (0.4%), and large cell neuroendocrine carcinoma (0.4%), in order of frequency. In men, squamous cell carcinoma was the most frequent type (55.1%). In women, adenocarcinoma was the most frequent type (39.7%). In both sexes, adenocarcinoma was the most common type in patients under the age of 40 (n=12, 41.4%), while squamous cell carcinoma proved the most frequent type in patients over the age of 40 (n=617, 51.3%). Changing trends of histologic types of lung cancer showed that the incidences of squamous cell carcinoma had significantly decreased throughout the years, whereas those of adenocarcinoma and small cell carcinoma had increased. In conclusion, the results showing increases in the percentage of female patients and in the number of cases of adenocarcinoma were noteworthy, and well correlated with other related reports.

Abstract PDF: Chronic bronchiolitis is a condition associated with cigarette smoking, and later associated with pulmonary parenchymal alteration and progressive deterioration of lung function. Early respiratory bronchiolitis was produced in Sprague-Dawley rats by indirect inhalation of cigarette smoke daily in a smoke exposure chamber designed by authors for 1 month. Experimental group A (n=5) was sacrificed after having smoked 30 cigarettes, group B (n=5) after 80 cigarette, and group C (n=7) after 140 cigarettes, respectively. Examination of morphologic changes in the lungs was done on light microscope, transmission and scanning electron microscopes. Light microscopically, increase in number of goblet cells in the bronchial mucosa, brown-pigmented macrophages in the alveoli, multifocal alveolar collapse adjacent to the bronchioles, dilatation of alveolar ducts and alveolar spaces were observed. Transmission electron microscopically, irregularly shaped Clara cells, alveolar wall collapse, and focally type I epithelial cell injury were seen. Scanning electron microscopically, scattered alveolar collapse, irregular dilatation of alveolar ducts, alveolar spaces and interalveolar pores (pores of Kohn) were seen. The terminal and respiratory bronchioles showed morphological alteration of Clara cells, but no evidence of cellular bronchiolitis or bronchiolar obstruction. We conclude that sidestream smoke induces an early respiratory bronchiolitis including aggregates of brown pigmented macrophages and varying degrees of structural alteration of adjacent pulmonary parenchyma.

Abstract: This study was designed to identify expression of calcium-binding proteins and synaptic reorganizations of dentate mossy fibers in hippocampal sclerosis of human temporal lobe epilepsy. Hippocampal neuronal density was quantitively analyzed in temporal lobe epilepsy group (n=50) to investigate the degree of hippocampal sclerosis and it was compared with that of autopsy control (n=3). To verify the distribution of calcium-binding proteins in neurons of epileptic hippocampi, the parvalbumin (PV)-immunoreactive and calbindin-D28K (CB)-immunoreactive neurons were quantitively analyzed in each area of Ammon's horn by immunohistochemical stain. Also, to clarify synaptic reorganizations of the dentate mossy fibers, a part of each hippocampus was examined under light microscopy and transmission electron microscopy using Timm sulphide silver method. In epileptic hippocampi, severity of hippocampal sclerosis (HS) was graded four, which consisted of 3 cases with no HS, 6 mild HS, 12 moderate HS, and 29 severe HS. The hippocampal neuronal loss was most prominent in CA1, followed by CA4 and CA2. Expression of calcium-binding proteins was more prevalent in CA2 of all groups. The proportion of PV-immunoreactive neurons in CA1 and CA4 significantly increased in the moderate and severe HS group, whereas the proportion of CB-immunoreactive neurons did not correlated with the severity of HS. Timm granules were noted in inner molecular supragranular layer of dentate gyrus of epileptic hippocampi and they tended to increase in proportion along with the severity of hippocampal sclerosis. Transmission electron microscopy showed that supragranular Timm granules corresponded to synaptic terminals of mossy fibers. These results suggest that parvalbumin appears to have more protective effect against neuronal loss and that mossy fiber synaptic reorganization seems to play a major role in pathogenesis of hippocampal sclerosis of human temporal lobe epilepsy.
