Autologous bone marrow grafts in dogs treated with lethal doses of 1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea. 1978

J Abb, and B Netzel, and H V Rodt, and S Thierfelder

Hematological and immunosuppressive effects of various single doses of 1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea (CCNU) were evaluated in the preclinical canine model. Immune function appeared not to be impaired by treatment with CCNU, but severe myelotoxicity contributed to the death of 3 of 4 dogs given 10 mg CCNU per kg and 5 of 5 dogs given 15 mg CCNU per kg within 10 days after drug administration. Infusions of autologous bone marrow protected 6 of 6 dogs receiving 15 mg CCNU per kg and 6 of 6 dogs receiving 20 mg CCNU per kg from lethal marrow failure. Dogs given 30 mg CCNU per kg and autologous marrow died within 7 days from severe gastrointestinal toxicity. We conclude that autologous bone marrow support may allow the use of high-dose CCNU regimens and thereby increase its therapeutic efficacy in the treatment of advanced cancer.

D007111	Immunity, Cellular	Manifestations of the immune response which are mediated by antigen-sensitized T-lymphocytes via lymphokines or direct cytotoxicity. This takes place in the absence of circulating antibody or where antibody plays a subordinate role.

D008130	Lomustine	An alkylating agent of value against both hematologic malignancies and solid tumors.	CCNU,Belustine,Cecenu,CeeNU,NSC-79037,NSC 79037,NSC79037
D009163	Mycobacterium bovis	The bovine variety of the tubercle bacillus. It is called also Mycobacterium tuberculosis var. bovis.	BCG,Calmette-Guerin Bacillus
D009607	Nitrosourea Compounds	A class of compounds in which the core molecule is R-NO, where R is UREA.	Compounds, Nitrosourea
D001853	Bone Marrow	The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001500	BCG Vaccine	An active immunizing agent and a viable avirulent attenuated strain of MYCOBACTERIUM BOVIS, which confers immunity to mycobacterial infections. It is used also in immunotherapy of neoplasms due to its stimulation of antibodies and non-specific immunity.
