The cases of spina bifida cystica with(More)
The effect on mouse typhoid infection of a 3-day treatment of female virgin mice with 1 mg/day of female sex hormones (estrogen or progesterone), maintaining the same hormonal levels observed in pregnant mice for 30 days, was investigated in order to clarify the mechanisms of altered resistance during pregnancy. Estrogen-exposed mice were more susceptible(More)
