Abstract Objective To observe the effect of Naoxueshu Oral Liquid on the expression of zonula occludens 1 (ZO-1), aquaporin-4 (AQP4) in brain of model rats with intracerebral hemorrhage. Methods A model of intracerebral hemorrhage was produced by injection of collagenase Ⅶ into the caudatum of rats. Healthy male SD rats of SPF grade (8 weeks) were divided into three groups by random number table: the sham group, the model group and the Naoxueshu group, with 8 rats in each group. Naoxueshu Oral Liquid was administrated intragastrically by 0.27 mL/(100 g·d), while saline was administrated to the sham group and model group by the same way. The histopathological change of brain tissue was tested by HE staining and transmission electron microscopy on the 7 d after intracerebral hemorrhage. The expression of ZO-1 and AQP4 in perihematoma tissue was detected by Western blot. Results Compared with the sham group, HE staining showed that large necrosis in perihematomal and the cells were irregular, loose, swollen, and the nuclear structure was unclear and undistinguishable in the 7-day model group. Transmission electron microscopy revealed that the gap between cerebral blood vessels and surrounding tissues was widened, and vacuolar changes were observed, and the astrocyte podocyte edema was obvious. The expression of ZO-1 protein in the brain tissue of the 7-day model group was decreased and AQP4 protein was increased (P ＜ 0.05). Compared with the model group, the pathological structure of the cerebral blood group was significantly improved, and the expression of ZO-1 protein was significantly increased, while the expression of AQP4 protein was significantly decreased (P ＜ 0.05). Conclusion Naoxueshu Oral Liquid can effectively increase the expression of ZO-1 protein and inhibit the expression of AQP4 protein, thereby reduce the permeability of blood-brain barrier and relieve encephaledema, and play a protective role in brain of model rats with intracerebral hemorrhage.
