Objective: To evaluate the usefulness and prognostic value of reactive hyperemia - peripheral arterial tonometry in patients with sepsis. Moreover, we investigated the association of reactive hyperemia - peripheral arterial tonometry results with serum levels of certain inflammatory molecules. Methods: Prospective study, conducted in an 18-bed mixed intensive care unit for adults. The exclusi...

hyperemia directly after release of the blood pressure cuff. As stated in our article, we did not measure reactive hyperemia but performed our measurements in all groups after 20 min of reperfusion. It is, therefore, unlikely that reactive hyperemia caused the observed differences between groups. We agree that further studies are needed to clarify more the mechanisms of helium preconditioning i...

During reactive hyperemia following a brief coronary artery occlusion, excess arterial inflow exceeds the blood flow debt incurred during occlusion by 300-600T. The present study was performed to determine whether this marked reactive hyperemia is essential for restoration of coronary vascular tone. Coronary blood flow was measured in unanesthetized dogs with electromagnetic flowmeters and hydr...

objective: salmonellosis is a bacterial disease with a rising prevalence in the cattle industry. it is most common in dairy calves one to ten weeks of age. salmonellosis has a serious economic impact on the cattle industry worldwide. methods: in may 2013, a three months old male holstein calf with the history of lateral recumbency was referred to veterinary hospital with severe depression, cach...

Because adenosine is commonly used for inducing maximal coronary hyperemia in the clinic, it is imperative that adenosine-induced hyperemia (AH) resembles coronary hyperemia that can be attained by endogenous stimuli. In the present study we hypothesized that coronary reactive hyperemia (RH) is limited compared with AH due to the presence of the glycocalyx and that the AH response is therefore ...

A utoregulation and Hyperemia of Cerebral Blood Flow as Evaluated by Thermal Diffusion • A thermal diffusion flow probe gave a quantitative dynamic recording of cerebral blood flow (CBF) during bleeding and transfusion in experimental animals. Autoregulation was readily demonstrated in nine of 12 animals and was found only with gradual hypotension. After autoregulation was lost, no increase in ...

OLSON, RAY A., AND DONALD E. GREGG Myocardial reactive hyperemia in the unanesthetised dog. Am. J. Physiol 208(2): 224230. I g65.-Studies of myocardial reactive hyperemia in dogs 5-24 days after the implantation of electromagnetic flowmeters on coronary artery branches reveal that the duration of occlusion and the control flow rate are independent determinants of the volume of reactive hyperemi...

Erratum After publication of the original article [1], the authors found that there was an error in describing "hyperemia", one of the three parameters of the macroscopic grading system of synovitis in the "Methods" section, an important description for the study. In the final third of the second paragraph of the "Macroscopic assessment of synovitis with arthroscopy" subsection of the "Methods"...
