Immunological Studies of Tumors

Histological and Immunological Evaluation of Gastrointestinal Stromal Tumors

Background: Gastrointestinal stromal tumors (GISTs) constitute the majority of gastrointestinal mesenchymal tumors. They usually express a proto-oncogen protein called CD117 detected by immunohistochemistry. This study investigated the differentiation of GISTs as well as the risk of aggressive behaviors in GISTs from surgically-treated patients in university affiliated hospitals. Methods: The c...

Immunological Studies in Pneumonia

The serum derived from human cases of pneumonia has been used to sensitize guinea pigs passively. As antigen an autolysate of a pneumococcus culture was employed. By means of Dale's method it has been possible to show with considerable regularity that the blood contains sensitizing antibodies during the course of pneumonia, but none after the crisis. Patients suffering from other diseases have ...

Immunological Studies of Insect Metamorphosis

1. The cell-free blood of the Cecropia silkworm produces a maximum of nine bands of antigen-antibody precipitate when reacted in antiserum-agar tests with antisera prepared by injecting Cecropia extracts into rabbits. The blood antigens producing these bands of precipitate have the properties of proteins in that they are non-dialyzable, labile at 75 degrees C., and salted out by 75 per cent sat...
