Article
Hyperthermia can be used as a possible adjuvant therapy in treatment of cancer patients. In this study, the direct effect of hyperthermia on osteosarcoma derived cell lines HOS85, MG-63 and SaOS-2 was investigated. Heat shock at 42 degrees C inhibited proliferation significantly in all three cell lines tested. Furthermore a sub-lethal heat shock (4...
Article
Artificial ligaments are a useful tool in ligament reconstruction. Although the new generation of artificial ligaments shows encouraging clinical results, in contrast to earlier generations studies on the biological properties are lacking. Biopsies were taken from a ligament advancement reinforcement system (LARS) 6 months after implantation and in...
Article
Neoadjuvant chemotherapy in osteosarcoma improves the survival dramatically, but there is currents drug resistance in about 25% of patients, leading researchers to investigate alternative therapy forms. Suramin has in the last two decades been used as salvage therapy in some cancers. This study was undertaken to investigate suramin as a possible sa...
Article
To determine serum levels of TNF-beta and soluble TNF-R in patients with primary highly malignant bone tumours. Sera of 27 patients with highly malignant osteosarcoma and Ewing sarcoma were taken at the time of diagnosis and analysed by ELISA. Both TNF-beta and sTNF-R levels were lower in sera from osteosarcoma patients as compared to those from Ew...
Article
The aim of this study was to evaluate serum levels of both soluble CD30 (sCD30) and soluble CD40 ligand (sCD40L) in patients with malignant bone tumours and to determine their ability to serve as serum markers. Sera of 31 patients were taken at the time of diagnosis, analysed by ELISA, and the results were correlated with clinical features and comp...
Article
Cytotoxic drugs used in neoadjuvant chemotherapy may exert their effect by activation of apoptosis. Both APO-1/Fas and Interleukin-1beta-converting (ICE)/caspase-1 are believed to act as mediators of apoptotic cell death. The sera of 21 patients with high-grade osteosarcoma were tested at the time of diagnosis by ELISA and compared with clinical da...
Article
As an adjuvant to chemotherapy hyperthermia has proven to be successful as a treatment for osteo- and chondrosarcoma patients. The aim of this study was to investigate whether hyperthermia could increase cellular expression of heat-shock-protein 72 in human osteo- and chondrosarcoma cells and how heat treatment would affect their susceptibility to...
Article
Heat shock proteins (HSPs) have been shown to represent potential target molecules for T-cell-mediated allograft rejection in heart and kidney transplants. In the present study, we therefore investigated the expression of HSP subtypes 60, 72, and 73 in normal kidneys and qualitative and/or quantitative changes in rejected renal allografts. Six norm...
Article
Heat shock proteins (hsp) are involved in tumor immunity, and a correlation with survival, occurrence of metastases, and drug resistance has been reported. It was the aim of this study to investigate the expression of heat shock proteins in chondrosarcomas and chondromas. Hsp expression was investigated immunohistochemically on paraffin-embedded se...
