Airway irritation effects after single and repeated inhalation exposures to aerosols of beta-glucan (grifolan) were investigated in mice. In addition, the effects on serum total immunoglobulin E (IgE) production and histopathological inflammation in the respiratory tract were studied. The beta-glucan aerosols provoked slight sensory irritation in the(More)
Using a highly sensitive chemiluminescent enzyme immunoassay, we have evaluated the measurement of serum prostate-specific antigen (PSA) as a potential diagnostic test for differentiation between women with breast cancer and those with benign breast disease. In a controlled study consisting of 284 women with well-documented patient files and matched for age(More)
Several malignant tumors accumulate hyaluronan, a matrix component suggested to promote cancer cell migration and growth. To explore the potential clinical importance of this concept, we assessed the hyaluronan levels in epithelial ovarian cancer. A biotinylated affinity probe specific for hyaluronan was prepared and applied to histological sections of 309(More)
The possible involvement of dopaminergic neurons in dementia of Alzheimer type (AD/SDAT) was studied in autopsied brains from 20 patients with AD/SDAT. Dopamine (DA) concentrations were decreased significantly in the temporal cortex, hippocampal cortex and hippocampus in AD/SDAT patients. Levels of homovanillic acid (HVA) were not altered compared to(More)

Hyaluronan (HA) is a linear high molecular weight extracellular polysaccharide. It is thought to be involved in mitosis and the enhancement of wound healing, tumor invasion, and metastasis. Because its clinical relevance in cancer has not been explored, we scored HA in colorectal adenocarcinoma and studied its relationship with patient survival. A specific(More)
To investigate changes in the somatostatinergic neurons of patients with Alzheimer's disease (AD), we determined the somatostatin-like immunoreactivity (SLI) in post-mortem brain tissue of histopathologically confirmed AD patients and in CSF of probable AD patients (according to DSM III). The CSF values were then correlated with psychological test scores.(More)
Hyaluronan (HA), an extracellular high-molecular-mass polysaccharide, is supposed to be involved in the growth and progression of malignant tumours. We studied the cellular expression of HA in 215 operated stage I-IV gastric cancer patients using a specific biotinylated probe. Most (93%) of the tumours showed HA staining in their parenchyma, whereas the(More)
A retrospective analysis of 321 gastric cancer patients was made to assess the prognostic value of TNM classification, tumour differentiation, Laurén classification, proliferative rate, inflammatory reaction and tumour invasion in vascular or neural structures of the gastric wall. The TNM classification showed the strongest correlation with survival in(More)
We have studied 118 renal cell carcinomas to analyse the expressions of cyclins A and D1 and p21(waf1/cip1), and their relationship to clinical and histopathological parameters as well as to clinical outcome. Cyclins A and D1 and cyclin-dependent kinase inhibitor p21 (waf1/cip1) were not expressed in normal renal tissue. Staining signals of cyclin D1 and(More)
The role and prognostic value of the tumour suppressor p21/WAF1 expression in epithelial ovarian cancer has not yet been defined. Therefore, the expression of p21/WAF1 was assessed immunohistochemically (IHC) in 316 epithelial ovarian malignancies in relation to p53, cell proliferation and patient survival. p21/WAF1 expression was inversely correlated with(More)
