This research attempted to determine the efficacy of tetrazolium test in evaluation seed viability two varieties Coffea arabica L. (‘Castillo’ and ‘Cenicafé’). The fruits were obtained from crops located municipalities Salazar de las Palmas Arboledas (Norte Santander - Colombia). was carried out with embryos manually extracted seeds using tweezers. Three pretreatments established: distilled wat...

Endotoxin-stimulated nitroblue tetrazolium (NBT) reduction was evaluated in 853 individuals: 270 healthy controls, 334 with various non-neoplastic conditions, 220 with solid non-lymphomatous tumours, and 29 with lymphoma. Each of the above groups was divided into three age subgroups: less than 60, 60-69, and greater than or equal to 70 years. In the controls and in patients with nonmalignant di...
The nitroblue-tetrazolium (NBT) slide test has been applied widely to assist in the diagnosis of bacterial infection. The test involves mixing a small amount of heparinized blood with a solution of NBT and noting the percentage of neutrophils that contain reduced NBT after a fixed period of incubation. Although it has been recognized that anticoagulants can influence the scores obtained, the me...
1 . Washed buffy-coat preparations of human blood suspended in different media were exposed to the Nitroblue Tetrazolium (NBT) and the mechanism of entry of the dye into neutrophil polymorphonuclear leucocytes was investigated. 2. Stimulation of neutrophils with endotoxin and the presence of heparin and/or fibrinogen in the suspending medium were necessary for dye reduction. 3. NBT complexed wi...
A simple test for toxic chemicals has been developed. Rhizobium meliloti is combined with the toxic chemical. A tetrazolium dye, MTT (3-[4,5-Dimethylthiazol-2-yl]2,5diphenyl-tetrazolium bromide) is added. The bacterium reduces this dye, causing the optical absorbance to increase dramatically. The increase can be determined with a simple spectrophotometer. Toxic chemicals and minerals inhibit th...
