Abstract:
Objective To investigate the effect of curcumin on brain glucose metabolism in rat models of intracerebral hemorrhage ( ICH), and evaluate the therapeutic effect of curcumin. Methods Twenty-four healthy adult male SD rats were randomly divided into 4 groups ( 6 rats/group) by simple random sampling method:normal group ( group A) , ICH+curcumin group ( group B) , ICH +vehicle group ( group C) , and sham operated group (group D). ICH model was made by injecting collagenase (2 μl) into the right cau-date nucleus of rat. 18F-FDG with a dose of (17.8±0.4) MBq was injected through caudal vein at 6 h, 24 h, 48 h, 3 d, 5 d, 7 d, 14 d after the model was built successfully. 18F-FDG microPET/CT was performed 30 min post injection at each time point. ROI in the hematoma and peri-hematoma brain tissue was drawn, and its volume and SUVmean were measured and analyzed. Meanwhile, each rat was evaluated by neurological severi-ty scores ( NSS) . Analysis of variance for repeated measurement data and Pearson correlation analysis were used. Results NSS in group B were lower than those in group C from 6 h to 5 d (F=183.26, P<0. 01). MicroPET/CT showed decreased glucose uptake in the hematoma and peri-hematoma brain tissue after cere-bral hemorrhage. In group B, the 18 F-FDG uptake in peri-hematoma brain tissue of ICH decreased after 6 h, and reached the minimum at 24 h (1.20±0.08), and then increased. The glucose metabolism in group B was significantly lower than that in group D at each time point (F=7306.74, P<0.01), and significantly higher than that in group C ( F=471.50, P<0.01) . SUVmean within ROI had a significantly negative correla-tion with both ROI volume and NSS in group B at each time point( r values:-0.672 and -0.727, both P<0. 05) . Conclusions MicroPET/CT might visualize decreased glucose uptake of hematoma and peri-hema-toma brain tissue after cerebral hemorrhage. Curcumin might have a neuroprotective effect on ICH, and im-prove the glucose uptake in hematoma and peri-hematoma brain tissue.
