The objective of this study was to determine the optimal cutoff value of serum adenosine deaminase (ADA) activity for diagnosing scrub typhus in acute febrile patients, especially in the autumn. A total of 715 febrile patients were included; 286 of them were diagnosed with acute scrub typhus. The mean serum ADA activities in patients with and without scrub typhus were 42.8 ± 13.4 IU/L and 17.2 ...

Adenosine deaminase has been measured in the lymphocytes of individuals with various types of solid tumors. The mean activity was found to be significantly lower when compared with control individuals of a similar age.

Adenosine deaminase (Enzymes Commission No 3.5.4.4) is an enzyme capable of catalysing the catabolism of purine bases. Previous studies have shown that this enzyme may be useful in recognition of a tuberculous aetiology of pleural, peritoneal, or meningeal effusions.-̀ s Adenosine deaminase assay is a simple, sensitive, and specific diagnostic procedure in these conditions but its use in diagnos...

The aim of this study was to determine the effect of exogenous GSH, an important antioxidant containing thiol group, on total antioxidant capacity (TAC) and total oxidant capacity (TOC), adenosine deaminase (ADA), a significant indicator of cellular immunity, and nitric oxide (NO) concentrations in rabbits. Sixteen healthy New Zealand rabbits were divided into 2 groups as control and GSH-treate...

The association of a human genetic deficiency of adenosine deaminase activity with combined immunodeficiency prompted a study of the effects of adenosine and of inhibition of adenosine deaminase activity on human lymphocyte transformation and a detailed study of adenosine metabolism throughout phytohemagglutinin-induced blastogenesis. The adenosine deaminase inhibitor, coformycin, at a concentr...

Objective: We have previously demonstrated that myocardium is capable of down-regulating its 0, requirements and thus avoiding ischaemia when 0, supply is limited. The present study tested the hypothesis that endogenous adenosine produced this protective response when 0, supply was decreased by moderate coronary hypoperfusion or moderate coronary hypoxaemia. Methods: In anaesthetised dogs, hear...

background :juvenile idiopathic arthritis (jia) is one of the most common chronic rheumatic diseases in children with unknown etiology and pathogenesis. it also has no diagnostic test and its clinical diagnosis is made through ruling out other types of arthritis. the aim of this study was to evaluate the level of ada (adenosine deaminase) in the serum of jia patients and to compare it with that...
