[Changes in the sialomucin content of cells of the Yoshida ascites hepatoma after radiotherapy. Cytophotometric analysis].
The X-ray (400 R) action on the membrane glycoproteins, glycolipids and sialic acid residues was studied in Yoshida ascites tumour cells. Some cells were pretreated with neuraminidase and then all were submitted to the Hale's reaction; the stain intensity was determined by integrating microdensitometer at a wave length of 660 nm. A significant decrease of the Hale-positivity (P less than 0,05) has been observed in cells submitted either to radiation or to enzyme treatment.
