  • Abstract
  • Look Inside

Induction in vivo of resistance of C6 rat glioma and 9L rat glioma to ACNU [1-(4-amino-2-methyl-5- pyrimidinyl) methyl-3-(2-chloroethyl)-3-nitrosoureahydrochloride) was studied and ACNU-resistant rat meningeal gliomatosis models were developed by using these resistant glioma sublines. Rapid acquisition of resistance to the agent was present at 2nd transplant generation in both glioma lines.

Cellular resistance to ACNU remained unchanged in the absence of drug over 5 transplant generations in vivo in spite of the fact that the drug treatment was discontinued at the 5th generation after a complete resistance was induced.
