Abstract | OBJECTIVE: METHODS: The gestational rats (15-17days) were randomly divided into sham operation group and transient intrauterine ischemia group. For transient intrauterine ischemia group, the gestational rats' bilateral uterine arteries were clamped for 30 min, followed by reperfusion. For sham operation, animals were subjected to the same surgical procedures, except that bilateral uterine arteries were not clamped. Samples were collected at 24, 48, and 72 h after reperfusion. The whole brain tissues were dissected for Nissl stain and Caspase-3 immumohistochemical. The expressions of GSK-3 beta and beta-catenin protein in the two groups were analyzed with Western Blotting. RESULTS: The Nissl body of the transient intrauterine ischemia group decreased and the masculine cell of Caspase-3 was significantly higher than sham operation group at each time point (P < 0.05). The sham operation group is 12.71 +/- 1.42 (24 h), 11.45 +/- 1.50 (48 h), 14.10 +/- 1.29 (72 h) and the transient intrauterine ischemia group is 26.29 +/- 1.64 (24 h), 32.38 +/- 1.05 (48 h), 39.20 +/- 1.88 (72 h). beta-catenin expression between the two groups was no statistically significant difference. However, expression of GSK-3 beta in transient intrauterine ischemia group increased (P < 0.05). The sham operation group is 1.75 +/- 1.07 (24 h), 1.34 +/- 1.03 (48 h), 1.48 +/- 1.10 (72 h) and the transient intrauterine ischemia group is 3.25 +/- 1.34 (24 h), 2.99 +/- 1.26 (48 h), 3.10 +/- 1.35 (72 h).
