[Catalase activity in Paramecium aurelia]. 1975

N Gros, and H Planel

The catalase activity of Paramecium aurelia was determined by the procedure of Sinha after bacteria elimination from culture medium. A significant level of catalase activity was shown, higher than in other cell kinds. The role of catalase activity in Paramecium sensitivity to low doses of ionizing radiations is discuted.

UI	MeSH Term	Description	Entries
D010247	Paramecium	A genus of ciliate protozoa that is often large enough to be seen by the naked eye. Paramecia are commonly used in genetic, cytological, and other research.	Parameciums
D011830	Radiation Effects	The effects of ionizing and nonionizing radiation upon living organisms, organs and tissues, and their constituents, and upon physiologic processes. It includes the effect of irradiation on food, drugs, and chemicals.	Effects, Radiation,Effect, Radiation,Radiation Effect
D002374	Catalase	An oxidoreductase that catalyzes the conversion of HYDROGEN PEROXIDE to water and oxygen. It is present in many animal cells. A deficiency of this enzyme results in ACATALASIA.	Catalase A,Catalase T,Manganese Catalase,Mn Catalase
D004754	Enterobacter	Gram-negative gas-producing rods found in feces of humans and other animals, sewage, soil, water, and dairy products.
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.
