本实验研究沙土鼠脑缺血预处理中转化生长因子β_1(transforming growth factor-betal,TGFβ_1)在海马CA1区的表达,并探讨TGFβ_1在脑缺血预处理中的作用。 材料和方法 动物及分组 63只成年健康沙土鼠(9~12周,50~70g),雌雄不拘,随机分成四组:非缺血对照组(A组,n=5);预
This study was designed to investigate the expression of transforming growth factor-betal (TGFβ_1) in hippocampal CA1 region of gerbil during cerebral ischemic preconditioning and to explore the role of TGFβ_1 in cerebral ischemic preconditioning. Materials and Methods Animals and Groups 63 adult healthy gerbils (9-12 weeks, 50-70 g) were randomly divided into four groups: non-ischemic control group (group A, n = 5)
