Abstrakt: Objectives: Intracerebral hemorrhage (ICH) occurs mostly in the striatum. In ICH, blood prolactin level increases 3-fold. The effects of intracerebroventricular injection (ICV) of prolactin on motor disorders will be investigated.
Materials and Methods: This study was performed on 32 male Wistar rats in 4 groups: sham, ICH, and prolactin with 1 μg/2 μl (P1) and 2 μg/2 μl (P2) doses.
Results: The weight of animals on days 1 ( P ˂0.01), 3, and 7 ( P ˂0.05) in the sham and P2 groups increased compared with the ICH group. Neurological Deficit Score (NDS) in ICH and P1 groups decreased, and increased compared with sham and ICH groups ( P ˂0.001), respectively. NDS in the P1 group increased compared with the P2 group on days 1 ( P ˂0.0 5), 3, and 7 ( P ˂0.001). The duration time of rotarod in ICH and P1 groups decreased and increased compared with sham and ICH groups ( P ˂0.001), respectively. The duration time of rotarod in the P1 group on days 3 and 7 increased compared with the P2 group ( P ˂0.001). Travel distance in days 1( P ˂0.01), 3( P ˂0.001), and 7( P ˂0.01) decreased in the ICH group. Prolactin receptor (PRL receptor) expression in ICH, P1, and P2 groups increased compared with sham and ICH groups ( P ˂0.001). Glial fibrillary acidic protein (GFAP) expression ( P ˂0.001) and apolipoprotein E (APOE) ( P ˂0.01) expression in the ICH group increased compared with the sham group. GFAP and APOE expression in the P1 group increased compared with the ICH group ( P ˂0.001). APOE expression in the P1 group increased compared with the P2 group ( P ˂0.001).
Conclusion: According to the results, prolactin reduces movement disorders.
