Results: The numbers of Bombesin positive pulmonary cells, the lamina propria S-l00 protein, neuron-specific enolase positive nerve fibers, IgE positive cells, mast cells and IgE positive mast cells significantly increased in bronchiectasis. The changes of pulmonary endocrine cells, nerve fibers and IgE positive cells were more significantly in hyperplastic BALT areas. The S-100 and NSE were found in lymphoid tissue and BALT. A close contact was found between mast cells and the S-100 positive nerve fibers. An IgE positive outer zone was found on MC surface. Mast cells and IgE positive cells were seen in the bronchial epithelium and alveolar septa.

Theurinary IL-6 level positively correlated with density of glomerular matrix membrane, global sclerosis, fiber or fibrocellular crescents and interstitial fibrosis (p. 05). According to the degree of density of glomerular matrix membrane and interstitial fibrosis, urinary Col-IV level had better correlation than urinary TGF-betal and IL-6 levels.In IgAN, Col-IV showed increased expression in diseased renal tissue whereas the site of expression of TGF-betal was mainly localized within the cytoplasm of tubular epithelial cells. Interstial expressionwas also present but glomerular TGF-betal expression was found only in patients with heavy mesangial proliferation. There was a significant correlation between glomerular positivity for Col-IV and severity of histological damage. There was also a significant correlation between positivity for TGF-betal and Col-IV in the tubular epithelial and interstitial lesions. In contrast, there was no ralationship between glomerular positivity for TGF-betal and severity of histological damage.The urinary TGF-betal level paralleled tubular TGF-betal expression.

objective the aim of this study is to investigate the expression and the distribution of the nerve growth factor during the period of neural tube development of human embryo.method early development of neural tube was studied in human embryos about 35 gestational days by using immunocytochemical abc technique.result there were ngf immuno-positive substances in the cytoplasm and nuclei of neuroepithelial cells in the ventricular zones of neural tube.in the intermediate zone of neural tube,ngf immunoreactivity was detected in the nuclei of some neurons,or the processes of other neurons which contained no ngf-immunoreactive substances in their nuclei;the expression pattern of ngf in the marginal zone of neural tube was similar to that of the intermediate zone.the density of ngf-immunorecative particles was higher on the rostrum side of neural tube than on the caudal side.the ngf immuno-positive cells were also observed among the somites of embryo under the neural tube.conclusion these results suggest that ngf was an important signal molecule to induce neural tube differentiation,and that ngf may play a significant role in regulation of the biological function of neurons in developing neural tube.
