Objective: To investigate the effect of Salvianolic acid B (Sal B) on the apoptosis of human umbilical vein endothelial cells (HUVECs) induced by intermittent high glucose and to explore the possible mechanisms.
Methods: HUVECs were preincubated with Sal B for 24 h, followed by incubation with intermittent high glucose (IHG, 5.5 mmol/L 12 h, 33.
Objective: To investigate the protective effect of sesamin on myocardial ischemia reperfusion injury in rats, and to study the possible mechanism.
Methods: 50 SD rats were randomly divided into control group, sham operated group, model group, high-dose sesamin group( 160 mg / kg) and low-dose sesamin group( 80 mg / kg),with 10 rats in each group. Rats in sesamin groups were administered intragastrically with sesamin for 7 d.
Objective: To investigate the effect of Danzhi Jiangtang Capsule on myocardial fibrosis in diabetic rats with fluctuated blood glucose and the possible mechanisms implicated.
Methods: Following induction of diabetes with intraperitoneal injection of streptozotocin (STZ), rats were administered with insulin or glucose at different time during a day to induce blood glucose fluctuation. After treatment with Danzhi Jiangtang Capsule for six weeks, rats were sacrificed and the hearts were collected for the determination of cardiac mass index.
Objective: To investigate the effect of serum containing sesamin on angiotension II (Ang II)-induced apoptosis in rat cardiomyocytes and the possible mechanisms.
Methods: H9c2 rat cardiomyocytes were preincubated with serum containing sesamin or blank serum for 12 h, followed by incubation with Ang II for 24 h. Cell viability was assessed by MTT assay and cell apoptosis was evaluated by flow cytometric analysis.
