Misonidazole and potentially lethal damage. 1982

M Korbelik, and B Palcic, and K Skov, and L Skarsgard

The existence of potentially lethal damage (PLD) is demonstrated in exponentially growing CHO cells exposed to misonidazole in hypoxia. The method of hypertonic post-treatment of cells was used in these studies. Misonidazole-induced PLD differs in many characteristics from radiation-induced PLD. The repair kinetics of misonidazole-induced PLD are much slower than for the repair of radiation-induced PLD (hours vs. minutes). No significant repair of misonidazole-induced PLD took place at 25 degrees C. Other differences are discussed. Hypertonic post-treatment of irradiated cells which had been pre-incubated with misonidazole to non-toxic levels, gave survival data consistent with the interpretation that no radiation PLD can be induced in such cells.

UI	MeSH Term	Description	Entries
D008920	Misonidazole	A nitroimidazole that sensitizes normally radio-resistant hypoxic cells to radiation. It may also be directly cytotoxic to hypoxic cells and has been proposed as an antineoplastic.

D009593	Nitroimidazoles	IMIDAZOLES having a nitro moiety.	Nitroimidazole
D010053	Ovary	The reproductive organ (GONADS) in female animals. In vertebrates, the ovary contains two functional parts: the OVARIAN FOLLICLE for the production of female germ cells (OOGENESIS); and the endocrine cells (GRANULOSA CELLS; THECA CELLS; and LUTEAL CELLS) for the production of ESTROGENS and PROGESTERONE.

D002470	Cell Survival	The span of viability of a cell characterized by the capacity to perform certain functions such as metabolism, growth, reproduction, some form of responsiveness, and adaptability.	Cell Viability,Cell Viabilities,Survival, Cell,Viabilities, Cell,Viability, Cell
D002478	Cells, Cultured	Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others.	Cultured Cells,Cell, Cultured,Cultured Cell
D003412	Cricetulus	A genus of the family Muridae consisting of eleven species. C. migratorius, the grey or Armenian hamster, and C. griseus, the Chinese hamster, are the two species used in biomedical research.

D006224	Cricetinae	A subfamily in the family MURIDAE, comprising the hamsters. Four of the more common genera are Cricetus, CRICETULUS; MESOCRICETUS; and PHODOPUS.	Cricetus,Hamsters,Hamster
D000332	Aerobiosis	Life or metabolic reactions occurring in an environment containing oxygen.	Aerobioses
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.
