Study design. a Three experimental groups were injected with [11C]PBR28, subjected to PET imaging of the abdomen and sacrificed for ex vivo biodistribution to determine standardized uptake values (SUV) in various organs and tissues. The healthy control group (n = 6, white) was terminated at day 4. 2,4,6-Trinitrobenzenesulfonic acid (TNBS) [30 mg/rat]-treated rats were terminated at either at day 4 (n = 6, gray) or day 11 (n = 6, black). b A group of rats (n = 6) was investigated by PET imaging of the brain 14 days before TNBS injection (baseline) and 4 and 11 days after TNBS injection.
