Objective To investigate the effect of grape seed proanthocyanidin extract (GSPE) on learning and memory ability after cerebral ischemia/reperfusion injury in rats and its mechanism. Methods 72 healthy male Sprague-Dawley rats were divided into sham group (n=18), model group (n=18) and GSPE groups (20 mg/kg, 200 mg/kg, n=18 for each group). The GSPE groups were administered GSPE orally for 4 weeks, while the sham group and model group were given water 10 ml/kg. Then their middle cerebral arteries were obstructed for 2 h and reperfused, excepted the sham group. 6 rats from each group were selected to test with Morris water maze 12 h, 24 h and 48 h after reperfusion respectively. And then, their brain tissues were stained with Hematoxylin-Eosin staining to observe under optical microscope. The level of superoxide dismutase (SOD) and malondialdehyde (MDA) in the brain tissues were measured. Results Compared with the sham group, the latency significantly prolonged, and the incidence of crossing the area the platform located reduced in the model group in the Morris water maze test, with the SOD decreasing and MDA increasing (P<0.05). Compared with the model group, the latency reduced and the incidence of crossing the area increased in the GSPE 200 mg/kg group, with the SOD increasing and MDA decreasing (P<0.05). Conclusion GSPE may suppress peroxidation after the cerebral ischemia/reperfusion to protect brain and learning and memory ability from injury.

Objective To explore the effect of endoplasmic reticulum stress (ER stress) in uric acid?induced phenotypic change in renal tubular epithelial cells (HK?2). Methods (1) HK?2 cells were cultured with 0, 75, 150, 225, 300 mg/L uric acid for 24 h in vitro. (2) The cells were divided into normal control group, ER stress inhibitor 4?PBA (5 μmol/L) group, uric acid (150 mg/L) group and 4?PBA+uric acid group for 24 h. Morphological changes of HK?2 cells were observed under inverted microscope. MTT assay was used to detect the proliferation of HK?2 cells treated with 150 mg/L uric acid for 24, 48 and 72 h. The protein expressions of α?smooth muscle actin (α?SMA), vimentin, snail, glucose regulated protein 78 (GRP78) and the phosphorylation of eukaryotic initiation factor 2α(p?eIF2α) in HK?2 cells were measured by Western blotting. Results Compared with the control group, HK?2 cells in uric acid groups (150, 225, 300 mg/L) showed fibroblast?like appearance. The protein expressions of α?SMA, vimentin, snail, GRP78 and p?eIF2α in 150 mg/L and 225 mg/L uric acid groups were higher than those in the control group (all P<0.05). The proliferation of HK?2 cells in 150 mg/L uric acid group was lower than that in control group at 48 and 72 h (all P<0.01). Compared with the uric acid group, the cell morphology in 4?PBA+uric acid group was improved, and the protein expressions ofα?SMA, vimentin, snail, GRP78 and p?eIF2α were decreased (all P<0.05). Conclusions Uric acid may induce the phenotype transformation of renal tubular epithelial cell, and ER stress is involved. 4?PBA may inhibit the uric acid?induced ER stress response and phenotypic transformation, and may be beneficial in attenuating uric acid?induced renal tubular damage.
