Nitric oxide concentrations in mammary quarters during heifer mastitis.
The aim of this study was to evaluate nitric oxide (NOx) concentration in infected and non-infected mammary quarters of dairy heifers before and after calving. The relationship between bacterial species and NOx concentrations, as well as correlation between NOx concentrations and postpartum somatic cell count (SCC), was assessed. Coagulase-negative staphylococci, Staphylococcus aureus and Esche...
متن کاملEvaluation of nitric oxide level in prepartum heifer mastitis
This study was carried out for detection of nitric oxide (NO) levels in healthy (Group 1, n:78) and infected (Group 2, n:63) quarters of pregnant heifers. The mean nitric oxide (NO) concentrations were calculated of about 15,58 ± 2,21 μM/ml and 42,69 ± 6,03 μM/ml for Group 1 and Group 2, respectively. A significant difference was found between two groups, statistically (p<0,001). The mean NO co...
متن کاملSteady-state nitric oxide concentrations during denitrification.
Three species of denitrifying bacteria, Paracoccus denitrificans, Pseudomonas stutzeri strain JM300, and Achromobacter cycloclastes, were allowed to reduce nitrate or nitrite in anaerobic, closed vials while the equilibration of gases between aqueous and gas phases was facilitated by vigorous stirring. The gas phase was sampled and analyzed for NO with use of a chemiluminescence detector calibr...
متن کاملSubclinical mastitis causes alterations in nitric oxide, total oxidant and antioxidant capacity in cow milk.
The aim of this study was to investigate total antioxidant (TAC), and oxidant capacity (TOC) and nitric oxide (NO) levels in milk of cows with subclinical mastitis. Brown Swiss and Holstein breed cows were screened with California Mastitis Test (CMT) to determine mammary glands with subclinical mastitis. Moreover, somatic cell counts (SCC) were determined electronically in all milk samples. Mam...
متن کاملNitric oxide metabolite concentrations in maternal plasma decrease during parturition: possible transient down-regulation of nitric oxide synthesis.
To elucidate the possible involvement of nitric oxide (NO) in parturition, we measured the maternal plasma concentrations of the NO metabolites, atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP) and guanosine 3',5'-cyclic phosphate (cGMP) in pregnant women at various gestational ages including those at vaginal and elective Caesarean deliveries. The plasma cGMP and NO metabolite ...
