[Radiation tolerance of normal lung-pulmonary radiation syndrome].

Radiation pneumonitis and radiation fibrosis are two distinct syndromes with probably different target cells. The ultrastructural changes occur rapidly and current evidence suggests that damage to the type II pneumocyte and the endothelial cell is linked to the pneumonia process than the fibrotic. The fibrosis process may be related to the basement membrane of both endothelial cells and alveolar type I cells. Dose time and volume data for tolerance dose are well documented in animals. Many antineoplastic agents enhances radiation lung damage. The pneumonitis and fibrosis will be discussed.

[Three dimensional CT reconstruction image using a personal computer].

Three dimensional (3D) images were reconstructed from axial CT slices using the personal computer. Some devices of the program made it possible to decrease the image processing time and to produce the realistic images with cubic effect. The thresholding in the conventional 3 D imaging was not practical especially in the display of the soft tissues. The employment of the volume rendering technique and MRI data will give a clue to the solution of these problems.

A case report of Paget's disease of the breast treated with radiotherapy alone.

Paget's disease of the breast is a rare form of breast cancer. Patients with nipple-areolar disease alone and no palpable mass have an excellent prognosis. Although there is some argument about the treatment of this type of Paget's disease, only two reports have been published on the role of conservative treatment. This report discusses a case of limited Paget's disease of the nipple and areola of the breast which was treated by radiation alone without limited surgery.
