    Notes: Summary Pituitary cells were isolated from adult human pituitary glands obtained at autopsy 4–12 h postmortem by enzyme treatment (collagenase and dispase) and by Percoll density gradients. Cells thus isolated were maintained in culture for more than 6 months. By immunoperoxidase staining methods using rabbit sera monospecific against various pituitary hormones, a large number of cultured cells reacted positively. The hormones identified in these cells were growth hormone, prolactin, adrenocorticotropin, follicle-stimulting hormone, luteinizing hormone and thyrotropin. Electron-microscopic examination of cultured cells revealed the presence of secretory granules in cytoplasm characteristic of in vivo human pituitary cells.

    Notes: Summary Ionizing irradiation induced marked morphological alterations in the Purkinje cell axons and axonic terminals in vitro. The myelinated segments demonstrated a very poor development of the myelin sheath. The axoplasm demonstrated various alterations of the mitochondria, and the smooth endoplasmic reticulum and the numerous elongated presynaptic terminals contained large aggregates of tubulovesicular structures and neurofilaments arranged in parallel and reticular array.

    Notes: Summary Cultured cells of neural origin (PC-12, pheochromocytoma cell line) respond to nerve growth factor (NGF) by extending neurites. These cells whether treated with NGF or not can be infected with herpes simplex virus and produce progeny virus. Viral antigens are detected on the cell surface and fusion of cells to form polykaryocytes takes place. Nucleocapsids are found within the cell nucleus and enveloped virus in present both in the cytoplasm and extracellular space. Virus was not observed within the neurites but alterations in the neurite microtubular structure occurred after infection.
