Adenine nucleotides and adenosine levels measurement in serum of Complete Freund’s Adjuvant (CFA)-induced arthritis rats and treated for 45 days with Uncaria tomentosa extract (150 mg/kg; 2 times/day). Purine levels measurement were log-transformed and are reported as log of nmol/ml. Groups: C (control), E (extract), A (arthritis) and A + E (arthritis + extract). Bars represent mean ± S.E.M
(^a,b) Indicates difference among the groups, P < 0.05 with n = 7 (two-way ANOVA-Newman-Keuls Multiple Comparison Test)
