  1. 6. Treatment of malignant tumors with histamine. Clinical and experimental studies

    Författare :Magnus Rizell; Göteborgs universitet; []
    Nyckelord :histamine; histamine H2-receptors; microdialysis; pharmacokinetics; ; neoplasm; sarcoma; melanoma; immunotherapy;

    Sammanfattning : For metastatic melanoma there is no treatment to prolong life. Histamine has in experimental tumors shown tumor inhibiting effects. In vitro, histamine inhibit phagocyte-derived radical oxygen species to protect natural killer and cytotoxic T-lymphocytes. LÄS MER

  3. 7. Cell signalling in cancer. A functional and immunochemical investigation of purinergic,adrenergic, nitrergic, and prostaglandin mediated signalling mechanisms in experimental and human cancer

    Författare :Gunnar Nylund; Göteborgs universitet; []
    Nyckelord :adenosine-5´-triphosphate; colon cancer; extracellular acidification; melanoma; ; microphysiometer; nitric oxide; noradrenaline; prostaglandin E2; sarcoma; tumour cell; metabolism; uridine-5´-triphosphate;

    Sammanfattning : Disturbed cell signalling is a hallmark of the cancer cell, being one important mechanismbehind uncontrolled cell growth. In the current study, we have investigated cancer cellsignalling with the focus on some first messenger and/or their receptors, in the murine celllines, MCG 101, and K1735-M2, and the human colon cancer cell line, HT-29.

  4. 8. Photodynamic therapy in the head and neck

    Författare :Mathias von Beckerath; Claes Möller; Göran Laurell; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Photo Dynamic Therapy; Cancer; Skin; Larynx; 5-ALA; UVradiation; sarcoma; squamous cell carcinoma; porfimer sodium; temoporfin; voice; Kirurgi; Surgery;

    Sammanfattning : Photodynamic therapy, PDT, is a method to diagnose and treat cancer. In PDT a sensitizer is administered to the patient and this sensitizer is accumulated in tumors. If the sensitizer-containing tumor is subjected to a laser of a specific wavelength the tumor is fluorescing allowing diagnostics. LÄS MER

  5. 9. Hormonal regulation of liver and tumor growth

    Författare :Ville Wallenius; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Liver; cytokine; interleukin-6; tumor necrosis factor; primary liver growth promoter; cyproterone acetate; nafenopin; hepatocyte growth factor; HGF receptor; tumor; sarcoma; N-terminal; truncated;

    Sammanfattning : The aims of this thesis were to investigate the regulatory functions of interleukin-6 (IL-6) and tumor necrosis factor-a (TNF-a) on liver growth, and the importance of hepatocyte growth factor (HGF) and the HGF receptor (Met) for growth of mesenchyme-derived tumors. The studies on different types of liver growth, measured as weight, DNA and protein content, and DNA synthesis, were performed on mice lacking the IL-6 or the TNF receptor-1 gene back-crossed to the C57bl/6 strain.

  7. 10. Clinical and Biological Patterns in Soft Tissue Sarcoma

    Författare :Emelie Styring; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiosarcoma; radiation-associated sarcoma; irradiated; RET; KIT; MYC.;

    Sammanfattning : Soft tissue sarcomas (STSs) are rare malignant tumors, of which 3/4 are high-grade and 1/3 metastasize. For optimal management, STSs should be treated at multidisciplinary sarcoma centers. LÄS MER
