Biometric characterization and tetrazolium test in Campomanesia phaea O. Berg. Landrum seeds

Antioxidant and Antihyperlipidemic Effects of Campomanesia adamantium O. Berg Root

Campomanesia adamantium O. Berg, popularly known as guavira, has been used in Brazilian traditional medicine for reduction of serum lipid. The present study was carried out to investigate the antioxidant and antihyperlipidemic effects of Campomanesia adamantium root aqueous extract (ExCA). Phenolic compounds were quantified in the ExCA and gallic and ellagic acids were identified by HPLC. ExCA ...

Campomanesia adamantium (Cambess.) O. Berg seed desiccation: influence on vigor and nucleic acids.

The aim of this study was to evaluate the sensitivity of Campomanesia adamantium seeds to desiccation by drying in activated silica gel (fast) and under laboratory conditions (slow). To assess the sensitivity of the seeds to desiccation, we used drying with silica gel and drying under laboratory conditions (25 °C), in order to obtain seeds with moisture content of 45, 35, 30, 25, 20, 15, 10 and...

Nitroblue tetrazolium test in experimental syphilis.

The reduction of nitroblue tetrazolium (NBT) by phagocytic leucocytes in peripheral blood has been examined in rabbits injected intratesticularly with Treponema pallidum, T. pallidum-free supernatant of orchitic testes, or normal rabbit testes supernatant. A significant (P less than 0.01) increase in NBT reduction was observed only in the infected animals.

Modification of the Berg acid phosphatase test.

The granulocyte nitroblue tetrazolium reductase test.

The nitroblue tétrazolium (N B T ) test is most useful for the diagnosis of chronic granulomatous disease and a few other rare metabolic abnormalities of neutrophils. It may be helpful in suggesting the presence of infection when values of both percentage of N BT positive neutrophils and total number of N BT positive neutrophils are markedly increased. Each patient must be inter­ preted with ca...
