SUMMARY 2000 ,Tehran schoolaged children, were included in a randomized trial to evaluate the risk factors for otitis media with effusion through interviews, a written questionnaire, otoscopy pneumatic and tympanometry. We found that the incidence of OME increased in children with parents who smoke (P<0.001) and were bottle fed as babies (P<0.005). Others factor such as, allergy, sinusitis, p...

The urethral muscle of diabetic pregnant rats is affected by long-term mild diabetes and short-term severe diabetes, which plays a crucial role in the pathogenesis of pelvic floor disorders. We hypothesized that muscles outside the pelvis are subject to similar changes. The current study aimed at analyzing the effects of long-term mild and short-term severe diabetes on the structure and ultrast...

The physiological changes of pregnancy tend to reset glucose homeostasis in the direction of diabetes. About 2-3% of all pregnant women develop abnormal glucose tolerance in pregnancy. Pregnancy complicated by diabetes leads to increased perinatal mortality and morbidity. Functional and morphological changes are present at cellular and tissue level. Furthermore, there are implications for the l...

Obstetrical and neonatal data were analysed for pregnancy outcome in 259 deliveries complicated by first or second trimester vaginal bleeding. There was a high incidence of low birth weight, low gestational age, perinatal death, asphyxia, breech delivery, placental infarcts and small-for-dates term infants. Fetal anomalies were slightly though not significantly increased. Combined suboptimal pr...

BACKGROUND When compared with the conventional surgical evacuation for the treatment of miscarriage, medical evacuation has been largely accepted as an effective and safe management. However, there is a lack of data on the long-term reproductive outcome of these two treatment modalities, which is crucial in patient counselling. The current study evaluates and compares the long-term fertility an...

A full-term pregnancy early in life reduces lifetime risk of developing breast cancer, and the effect can be mimicked in rodents by full-term pregnancy or short-term treatment with exogenous estrogen and progesterone. To gain insight into the protective mechanism, 15 3-mo-old postpubertal virgin Lewis rats were randomly assigned to three groups: control (C), pregnancy (P), or hormone (H). The P...

This experiment was conducted to determine the reproductive performance of Arabian ewes treated with short and long-term progesterone devices in addition to low doses of equine chorionic gonadotropin (eCG) during the anoestrus season. A total of 36 ewes were divided into three groups: in group I vaginal sponges (60 mg medroxy progesterone acetate; (MAP)) were applied and removed after 6 days; i...
