Effect of Uncaria tomentosa (UT) on metabolic parameters of ob/ob animals. Adult ob/ob mice fed with standard chow were divided into two groups: control (ob/ob) and UT (ob/ob+UT), which received 50 mg.kg−1 b.w. of crude plant extract (UT) diluted with saline, for 5 consecutive days, once a day, via gavage. The animals were isolated in CLAMS chambers. After two days of adaptation, the mice received either vehicle (saline) or UT, 50 mg.kg−1 b.w., once a day for 5 days (ob/ob+UT), via gavage. During the last 3 days, food intake to calculate the caloric intake (A), O2 consumption (VO2) (C), CO2 production (VCO2) (D), and the respiratory coefficient (RER) (E) were measured. Body mass index was calculated at the end of the period (B). The results are represented as mean ± SEM, n = 4 to 5. The statistical difference was analyzed by Student’s t-test or two-way ANOVA.
