Sildenafil citrate modifies fetoplacental development in a rabbit model of intrauterine growth restriction

The failure of fetuses to achieve the ir full growth potential is known as intrauterine growth restriction (IUGR). Silde nafil citrate (SC) is a phosphodiesterase 5 (PDE 5) inhibitor, which enhances nitric oxide (NO) dependent vasodilatation, adn it may have a potential therapeutic role in the treatment of IUGR.

Feto-placental development in the rabbit is altered by maternal food restriction from early pregnancy

Feto-placental development in the rabbit is altered by maternal food restriction from early pregnancy Maternal under-nutrition can induce Intrauterine Growth Restriction by placental insufficiency. To determine the consequences in the rabbit feto-placental unit, 32 pregnant rabbits were allocated in three feeding groups: ad libitum diet (Group C; n=9); restricted to 50% of their ad libitum intake during the pre-implantational period (Day 0 to Day 7) (Group PR; n=11) or restricted from Day 0 to Day 28 (Group TR; n=12).
