The effects of platelet lysate on maturation, fertilization and embryo development of NMRI mouse oocytes at germinal vesicle stage.

Purpose: Improving in vitro maturation could increase the rate of pregnancy from oocytes matured in vitro. Consequently, patients will be prevented from using gonadotropin with its related side effects. In this study, the maturation medium was enriched by platelet lysate (PL), then maturation and subsequent developments were monitored.

Identification of site of morphine action in pregnant wistar rat placenta tissue: a c(14)-morphine study.

Objective: In previous studies it has been emphasized that the site of morphine action may be either in the embryo or the placenta. In the present study, we attempt to identify the site of morphine action on the fetal section of Wistar rat placenta by using C(14)-morphine.

Materials And Methods: IN THIS STUDY (EXPERIMENTAL), FEMALE WISTAR RATS (WEIGHTS: 170-200 g) were mated with male rats and their coupling times recorded.

The effect of morphine consumption on plasma corticosteron concentration and placenta development in pregnant rats.

Background: Previous studies have shown that morphine consumption during pregnancy may delay embryo development or cause abnormal nervous system function.

Objective: The present study focused on the effect of maternal morphine consumption on development of placenta and blood corticosteron concentration in addictive pregnant mothers.

Materials And Methods: 24 female rats, 170-200g weight, were used.

Milled Stress Reduces Morphine-Induced Locomotion in F2 NMRI Mice.

Unlabelled: In the present study, the effects of pregnant NMRI mice restraint stress on the responsibility of their children to the behavioral properties of morphine, sulpiride and dextromethorphan were investigated in the F2 generation.

Twenty Four Pregnant Nmri Female Mice (w: 25 g) were divided into the experimental and control groups (n = 12/group). Animals in the experimental group were kept in the restraint cylinder (ID = 6 cm, L = 20 cm) for 60 min/day for 15 consecutive days, while the control group did not receive stress.

Effect of extract on in vitro maturation and developmental competence of immature mouse oocytes.

Purpose: This experiment examined the effect of L. extract on in vitro maturation, in vitro fertilization (IVF) and subsequent developmental competence of mouse oocytes.

Materials And Methods: Cumulus oocyte complexes (COCs) at germinal vesicle stage were collected from female Naval Medical Research Institute (NMRI) mouse ovaries.
