[Capacity of nitroblue tetrazolium-reduction of neutrophilic granulocytes (author's transl)]. 1975

C Eschenbach, and G Seebach, and S Müller-Lissner

A modification of the NBT-reaction is described which allows a differentiation of the NBT uptake and NBT-reduction. By means of this method it has been shown that the capacity of NBT-reduction of neutrophil granulocytes taken from hematologically healthy persons is independent of the probands' age and, moreover, of the presence of acute infections and their etiology. It has been shown, that the increase in the NBT-reduction of neutrophilic granulocytes of newborns and persons with acute bacterial infections results from an increased NBT-ingestion. To grive an example of a strongly reduced capacity of NBT-reduction of the neutrophilic granulocytes 2 patients suffering from fatal granulomatous disease in childhood have been examined.

D008431	Maternal-Fetal Exchange	Exchange of substances between the maternal blood and the fetal blood at the PLACENTA via PLACENTAL CIRCULATION. The placental barrier excludes microbial or viral transmission.	Transplacental Exposure,Exchange, Maternal-Fetal,Exposure, Transplacental,Maternal Fetal Exchange
D009504	Neutrophils	Granular leukocytes having a nucleus with three to five lobes connected by slender threads of chromatin, and cytoplasm containing fine inconspicuous granules and stainable by neutral dyes.

D009580	Nitroblue Tetrazolium	Colorless to yellow dye that is reducible to blue or black formazan crystals by certain cells; formerly used to distinguish between nonbacterial and bacterial diseases, the latter causing neutrophils to reduce the dye; used to confirm diagnosis of chronic granulomatous disease.	Nitro-BT,Nitrotetrazolium Blue,Tetrazolium Nitroblue,Blue, Nitrotetrazolium,Nitroblue, Tetrazolium,Tetrazolium, Nitroblue
D010084	Oxidation-Reduction	A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471).	Redox,Oxidation Reduction
D011247	Pregnancy	The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.	Gestation,Pregnancies
D001724	Birth Weight	The mass or quantity of heaviness of an individual at BIRTH. It is expressed by units of pounds or kilograms.	Birthweight,Birth Weights,Birthweights,Weight, Birth,Weights, Birth
D005260	Female		Females
D006105	Granulomatous Disease, Chronic	A defect of leukocyte function in which phagocytic cells ingest but fail to digest bacteria, resulting in recurring bacterial infections with granuloma formation. When chronic granulomatous disease is caused by mutations in the CYBB gene, the condition is inherited in an X-linked recessive pattern. When chronic granulomatous disease is caused by CYBA, NCF1, NCF2, or NCF4 gene mutations, the condition is inherited in an autosomal recessive pattern.
