[Effect of GnRHa controlled ovarian hyperstimulation on mouse embryo implantation and its mechanism].

The purpose of the present study was to investigate the effects and underlying mechanism of gonadotropin-releasing hormone agonist (GnRHa) controlled ovarian hyperstimulation (COH) on embryo implantation in mice. Forty female Kunming mice aged 9 weeks were randomly divided into two groups (control and COH groups). The COH group received intraperitoneal (i.

Impacts of exposure to 900 MHz mobile phone radiation on liver function in rats.

Objective: To study the impacts of exposure to electromagnetic radiation (EMR) on liver function in rats.

Methods: Twenty adult male Sprague-Dawley rats were randomly divided into normal group and radiated group. The rats in normal group were not radiated, those in radiated group were exposed to EMR 4 h/ d for 18 consecutive days.

[Effect of Bushen Tiaojing Recipe containing serum on FSH/cAMP-PKA pathway in in vitro cultured human ovarian granular cells].

Objective: To explore the potential molecular mechanisms for Bushen Tiaojing Recipe (BTR) improving the endocrine function of ovarian granular cells by observing the effect of BTR containing serum on follicle stimulating hormone/cyclic adenosine monophosphate-protein kinase A (FSH/ cAMP-PKA) pathway in in vitro cultured human ovarian granular cells.

Methods: The primary ovarian granular cells collected from in vitro fertilization-embryo transfer patients were cultured for 24 h. The human and rat serum containing different concentrations of BTR (low, medium, high dose), and their normal serums were co-incubated with ovarian granular cells for 48 h respectively, and then they were divided into the low, medium, high dose BTR groups and the control group.

[Effect of resveratrol on heart function of rats with adriamycin-induced heart failure].

Objective: To observe the protective effects of resveratrol (RES) on the heart function of the rats with adriamycin-induced heart failure.

Method: Thirty adult male SD rats were randomly divided into 5 groups: normal control (NC) group, adriamycin (ADR) group, RESL + ADR group, RES(H) + ADR group and RES group. RES of 30, 120, 120 mg x kg(-1) x d(-1) was given intraperitoneally (ip) once a day for 3 days in RES(L) + ADR group, RES(H) + ADR group and RES group respectively.

[Roles of potassium channel in effects of resveratrol on isolated myocardial contractility and heart rate research in guinea pig].

Objective: To study the effects of resvaratrol derivatives on spontaneous HR and CF of isolated guinea pig atrium.

Method: The dose-effect curve of resvaratrol was observed. The possible mechanism of potassium channels responsible for changes of CF and HR after administering with resvaratrol was measured.
