    Scanning electron microscopy of the subarachnoid macrophages after subarachnoid haemorrhage, and their possible role in the formation of subarachnoid fibrosis (1979)
    Springer
    Acta neurochirurgica 50 (1979), S. 273-280 
    Details
    ISSN: 0942-0940
    Keywords: Macrophage ; subarachnoid haemorrhage (SAH) ; subarachnoid fibrosis ; scanning electron microscope (SEM)

    Topics: Medicine
    Notes: Summary Sixty dogs with experimental subarachnoid haemorrhage (SAH), repeated SAH, and subarachnoid fibrosis (examined three weeks and three months after SAH, and treated with urokinase or dexamethasone) were examined by scanning electron microscope (SEM). The authors observed the resting and activated macrophages, the erythrophagocytosis, and giant cells in the subarachnoid space after SAH. They consider that the macrophages play an important role in the formation of subarachnoid fibrosis, similar to the role of macrophages in fibrosis in other sites.

    Arachnoid villi affected by subarachnoid pressure and haemorrhage (1979)
    Springer
    Acta neurochirurgica 51 (1979), S. 63-72 
    Details
    ISSN: 0942-0940
    Keywords: Arachnoid villi ; subarachnoid hemorrhage (SAH) ; increased subarachnoid pressure ; scanning electron microscope (SEM)
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary The arachnoid villi of 18 dogs were studied. The authors confirmed the pressure gradient changes of the morphology of arachnoid villi of dogs with the scanning electron microscope (SEM). A subarachnoid infusion with 5–10 times higher pressure gradient than the physiological one, tore the superficial endothelial layer from the villi, and the inner part could also be observed stereoscopically. On the surface of the arachnoid villi the authors observed microvilli, openings of vacuoles and intercellular gaps, but did not find openings of preformed channels. After subarachnoid haemorrhage (SAH) generally the villi were blocked but the authors have observed a red blood cell escaping from a villus intercellularly.

    Enhanced melanogenesis of murine melanoma cells cultured on or in collagen gel (1990)
    Springer
    Archives of dermatological research 282 (1990), S. 263-266 
    Details
    ISSN: 1432-069X
    Keywords: B16 melanoma cell ; Collagen gel ; Tyrosinase ; Melanogenesis ; Cell growth

    Topics: Medicine
    Notes: Summary To elucidate the interaction between melanoma and its matrix, we cultured B16 murine melanoma cells on and in type I collagen gel and evaluated specified functions of melanoma cells; tyrosinase activity and melanin-synthesizing capacity. Proliferation of cells cultured in these environments was markedly suppressed compared with that of cells cultured conventionally on plastic. On the other hand, the tyrosinase activity of cells cultured in or on collagen gel was two to three times higher than that of cells cultured on the plastics, while their melanin production was approximately double that achieved during conventional culture of cells. In conclusion, collagen gel influenced the growth and cell-specific functions of the melanoma cell. The culture system using collagen gel as substrate may be useful for the investigation of the interaction between melanoma and its matrix.
